iPhone Slowdown

Jump to Guides Articles
Apple in iOS 10.2.1 introduced power management features for older iPhones to prevent unexpected shutdowns during times of peak power draw on devices with degraded batteries.

These power management features throttle the processor on older iPhones with less than optimal batteries, resulting in slower performance. Though introduced early in 2017, the power management features were not widely publicized until late 2017, leading many customers to feel deceived by Apple.

Apple has apologized for not better explaining how battery health could impact performance and has since implemented a policy offering no-questions-asked $29 battery replacements for the iPhone 6 and later.

iOS 11.3 will introduce much more detailed information about battery health, letting customers know if the state of their battery is impacting processor performance. The update will also allow the power management feature to be turned off. Currently, the iPhone 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus, and SE are affected, but the processor is only slowed down occasionally when the battery can't meet the power demands of system intensive tasks.

Replacing a degraded battery with a fresh battery successfully eliminates the power management feature and restores a device that was previously being throttled to its full performance capacity.

Apple is facing multiple lawsuits and government inquiries about its decision to throttle processor performance, but the company is adamant that the feature was not introduced to prompt customers to buy a new iPhone. Instead, it is meant to extend the life of an iPhone as long as possible, because in Apple's opinion, an iPhone that occasionally sees slower performance is preferable to one that shuts down.

How to Disable Apple's Performance Management Features in Older iPhones in the iOS 11.3 Beta

Starting with the second beta of iOS 11.3, Apple has introduced a new "Battery Health" feature that's designed to provide you with more information about the state of your battery and whether or not it's impacting device performance. If your iPhone has a degraded battery that is leading to throttling issues, the "Battery Health" section will let you know about it, and it will provide an option to turn off performance management to put a stop to any throttling that's going on. There are, however, some nuances to this feature that you need to know about, which we'll outline below. When Installing iOS 11.3 When you first install the iOS 11.3 update, all performance management features that might have been enabled are automatically disabled. So when you first install the beta, you don't need to do anything because performance management is turned off. You will, however, need to watch out for an unexpected shutdown that turns your device off, because if this happens and you have a bad battery, performance management will be turned back on. More on this below. Accessing Battery Health You can check out the status of your battery in the new Battery Health section, which will tell you the maximum capacity of the battery in your iPhone and whether or not it's running at peak performance capacity. Here's how to get to it: Open up the Settings app. Scroll down to "Battery" and tap it. Tap on "Battery Health." All the info you need to know about your battery is listed here. Maximum Capacity will let you know how your battery is performing overall, and it

Apple Did Not Consider How Battery Replacement Program Would Impact iPhone Upgrade Rates

During today's earnings call covering the first quarter of 2018, Apple CEO Tim Cook was asked whether investors should be concerned about slowing upgrade rates due to Apple's battery replacement program and the fact that consumers may opt to replace their batteries instead of purchasing a new iPhone. In response, Cook said that he couldn't answer because it wasn't something that Apple took into account. Apple "did not consider, in any way, shape, or form, what it would do to upgrade rates," said Cook.We did it because we thought it was the right thing to do for our customers. I don't know what effect it will have for our investors. It was not in our thought process of deciding to do what we've done.In the same answer, Cook said the iPhone has fantastic reliability, and that the previously-owned market is continually expanding, with customers handing down older iPhones and using trade-ins to get new devices. Cook said he believes customers handing their devices down is a positive, because "the more people on iPhone, the better." Following the revelation that Apple introduced power management features that slow older iPhones in order to prevent unexpected shutdowns in devices with degraded batteries, Apple was accused of planned obsolescence and deliberately slowing devices to prompt customers to upgrade. Apple has vehemently denied that the power management features were implemented to spur customers to upgrade, and the company has said that instead, the features were meant to expand the life of an iPhone for as long as possible. Apple has apologized for the

iOS 11.3 Beta to Get Throttling Kill Switch in February as Apple Trials 'Reserve a Battery' System in Canada [Updated]

Following a report that the United States government is investigating Apple's power management function that slows down some older iPhone models, Apple issued a statement on late Tuesday confirming that it has "received questions from some government agencies" and is "responding to them." In the statement, Apple also confirmed the timing of its promised power management toggle, allowing customers with an iPhone 6 through iPhone 7 Plus to disable the function: it will be rolling out in a future iOS 11.3 beta version in February. The software update will be publicly released later this spring. Apple's full statement was shared by Axios earlier today:About a year ago, we delivered a software update that improves power management during peak workloads to avoid unexpected shutdowns on certain iPhones with older batteries. We know that iPhones have become an important part of the daily lives of our customers and our intention was to improve the customer experience. We sought to further improve the customer experience in December by announcing a significant discount on replacement batteries for certain iPhones. We also announced that we began developing a new iOS feature to show battery health and which would recommend when the user should consider replacing their battery. These actions were taken to further assist our customers and help extend the life of their iPhones. In addition, users will be able to see if the power management feature is being used to prevent unexpected shutdowns, and turn if off if they so choose. These features will be included in a developer

U.S. Government Investigating Apple's Power Management Features That Slow Older iPhones

Apple is continuing to face scrutiny over the power management features it introduced in older iPhones last year, with the U.S Department of Justice and the U.S Securities and Exchange Commission launching an investigation into the company, reports Bloomberg. The DoJ and the SEC are aiming to determine whether Apple violated security laws "concerning its disclosures" when it launched an iOS 10.2.1 update that throttled some older iPhones with degraded batteries in order to prevent unexpected device shutdowns. According to Bloomberg's sources, the government recently requested information from Apple and the investigation is in the early stages. Apple in iOS 10.2.1 introduced a new power management feature to address complaints of unexpected shutdowns in iPhone 6 and 6s iPhones. The shutdowns were caused by batteries below optimal health drawing too much power. At the time, Apple did not make it clear that to solve the issue, it was throttling the iPhone's processor at times of peak usage to limit power draw, and that lack of information has led to the company's current predicament. The full details behind the power management feature implemented in iOS 10.2.1 were not explained until benchmark testing revealed older iPhones with degraded batteries were being deliberately slowed down, and without an adequate explanation from Apple, customers were outraged and dozens of lawsuits were filed. Apple has since apologized and made reparations in the form of a new no-questions-asked discounted battery replacement program available to customers who have an iPhone

iOS 11.3 Coming This Spring With New Animoji, Vertical ARKit, Health Records, Battery Info, and More

Apple today previewed iOS 11.3, its next major iPhone, iPad, and iPod touch software update. The first beta has been seeded to developers today, with a public beta coming soon, ahead of an official release this spring. iOS 11.3 introduces new Animoji on the iPhone X, including a lion, bear, dragon, and skull. There will now be 16 characters to choose from in total, including existing ones like a pig, fox, chicken, pile of poo, and robot. iOS 11.3 will feature ARKit 1.5. In addition to horizontal surfaces like tables and chairs, Apple's updated augmented reality platform will now be able to recognize and place virtual objects on vertical surfaces like walls and doors, and more accurately map irregularly shaped surfaces like circular tables. ARKit 1.5 can find and recognize the position of 2D images such as signs, posters, and artwork, and integrate these real-world images into augmented reality experiences, such as bringing a movie poster to life. In addition, the view of the "real world" will now be in 1080p HD, up from 720p currently. The software update will introduce Business Chat, a new way for users to communicate directly with businesses within the Messages app. This feature will launch in beta following the public release of iOS 11.3 this spring, with support from select businesses, including Discover, Hilton, Lowe's, and Wells Fargo. With Business Chat, it's easy to have a conversation with a service representative, schedule an appointment or make purchases using Apple Pay in the Messages app. Business Chat doesn’t share the user’s contact

iOS 11.3 Will Allow iPhone Users to View Battery Health and Disable Apple's Power Management This Spring

Apple today announced that iOS 11.3 will provide users with an iPhone 6 or newer with more information about the health of their device's battery, including a recommendation if it needs to be serviced. In the same menu, it will also be possible to see if Apple's power management feature is active and turn it off. Apple is delivering on its promise to provide iPhone users with more visibility about battery health as part of an apology over its lack of transparency about power management changes it made starting in iOS 10.2.1. Apple is also delivering on its promise of allowing users to disable the feature, although it doesn't recommend it. The power management changes fueled an argument that Apple intentionally slows down older iPhones at wholesale to encourage customers to upgrade to newer models. Apple denied it would ever do anything to "intentionally shorten the life" of any of its products, but some critics don't believe that to be true. Apple also reduced the price of replacement batteries to $29 for iPhone 6 and newer through December 31, 2018, as another part of its apology, although supplies are running low for some iPhone models. MacRumors put together a list of frequently asked questions about Apple's power management changes for those looking for more information. The first beta of iOS 11.3 will be seeded to developers later today, followed by a public beta soon. The software update will be released to the public this spring for iPhone 5s and newer, all iPad Air and iPad Pro models, the fifth-generation iPad, iPad mini 2 and newer, and the

Investigations into Apple's iPhone Battery Slowdowns Spread to Italy and South Korea

Italy and South Korea on Thursday joined a growing list of countries in which class-action lawsuits and government investigations into Apple's iPhone battery slowdowns are underway. Italy's antitrust body revealed it had opened a probe into allegations that Apple used iOS updates to slow older smartphones and push clients into buying new models (via Reuters). The Italian watchdog said Apple had failed to inform customers that the updates might have a negative impact on the performance of their phones, suggesting the company might have infringed four separate articles of the national consumers' code. In a first among the recent wave of battery probes, Samsung is also suspected of orchestrating "a general commercial policy taking advantage of the lack of certain components to curb the performance times of their products and induce consumers to buy new versions," said the Italian watchdog. If found guilty, the two companies risk multi-million euro fines. Meanwhile, a South Korean consumer group has filed a criminal complaint against Apple CEO Tim Cook, accusing his company of defrauding iPhone users by slowing down devices without warning to compensate for poor battery performance. In its complaint, filed Thursday, the advocacy group Citizens United for Consumer Sovereignty accused Apple of destruction of property and fraud. According to Reuters, the group also represents around 120 plaintiffs in a civil damage suit filed against Apple earlier in January. Apple has already admitted that it slows down some older iPhones with degraded batteries during times

Chinese Consumer Group Demands Answers From Apple Over Older iPhone Slowdowns

Apple's iPhone slowdown controversy extended to China on Tuesday after a Chinese consumer group asked the tech giant for information about iOS updates that reduce the performance of older iPhones (via Reuters). The Shanghai Consumer Council has written to Apple and requested an explanation for the slowdowns and information about what Apple planned to do to rectify the problem. The consumer group, which is a non-government organization approved by the Chinese authorities, demanded a response by Friday, according to state news agency Xinhua. The council explained that its query came in response to consumer feedback that old iPhones became sluggish after upgrading the operating system to iOS 10.2.1. It said it had received 2,615 complaints about Apple products and services in 2017, compared to 964 complaints in 2015. Last month Apple confirmed that it introduced power management features in the update to improve performance and prevent unexpected shutdowns as the battery in the devices starts to degrade. The company faces an increasing number of lawsuits that either accuse the company of intentionally slowing down older iPhones, or of failing to disclose power management changes it made starting in iOS 10.2.1. For more information about the power management system that Apple implemented in the update, check out our frequently asked questions.

Apple Sued Over Meltdown and Spectre in U.S. as iPhone Slowdown Lawsuits Now Total 45

Apple faces its first legal action over Meltdown and Spectre in the United States, even though the vulnerabilities were found to affect nearly all computers and other devices, according to court documents reviewed by MacRumors. Meltdown and Spectre are serious hardware-based vulnerabilities that take advantage of the speculative execution mechanism of a CPU, allowing hackers to gain access to sensitive information. All modern Intel, ARM, and AMD processors are affected, with many patches and mitigations already released. Anthony Bartling and Jacqueline Olson filed a class action complaint against Apple last week in a U.S. district court in San Jose on behalf of anyone who purchased a device with an ARM-based processor designed by Apple, ranging from the A4 to A11 Bionic chips used in iPhone, iPad, iPod touch, and Apple TV models. The complaint alleges that Apple has known about the design defects giving rise to the Meltdown and Spectre vulnerabilities since at least June 2017, and could have disclosed details to the public more promptly. An excerpt from the complaint:ARM Holdings PLC, the company that licenses the ARM architecture to Apple, admits that it was notified of the Security Vulnerabilities in June 2017 by Google's Project Zero and that it immediately notified its architecture licensees (presumably, including Apple) who create their own processor designs of the Security Vulnerabilities.The complaint added that it is unlikely Apple would be able to fully and adequately release fixes for Meltdown and Spectre without the performance of its processors

Office Depot and OfficeMax Offering $28 Aftermarket iPhone Battery Replacements Until February

Office Depot and OfficeMax today informed us they have lowered their iPhone battery replacement fee to $27.99 at select stores across the United States through February 4, 2018, undercutting Apple's $29 price by one dollar. The lower price, down from $49.99 regularly, is applicable to the iPhone 5c, iPhone 5s, iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone 7, iPhone 7 Plus, and iPhone SE, subject to battery availability and while supplies last. Office Depot and OfficeMax promise same-day battery replacements. If the order is not completed by the end of regular store hours, the customer receives a repair discount of $25, according to fine print on its website. One very important caveat is that Office Depot and OfficeMax are not Apple Authorized Service Providers, meaning their replacement batteries are not supplied by Apple, and having an aftermarket battery installed can void your iPhone's warranty, although iFixit argues that Apple cannot do so under U.S. law. A spokesperson for Office Depot and OfficeMax informed us that their iPhone batteries are built to Apple's specifications for each iPhone model and added that all of their batteries carry a one-year warranty against defects. We still highly recommend only having an Apple Store or Apple Authorized Service Provider replace your iPhone's battery, but Apple is currently running low on some batteries, and Office Depot and OfficeMax may be an option worth considering for customers with an iPhone that is already past its warranty. Office Depot and OfficeMax offer iPhone battery replacements

Apple Delays iPhone 6 Plus Battery Replacements Until March-April Due to Limited Supply

iPhone 6 Plus users hoping to take advantage of Apple's discounted $29 battery replacements may have to wait a few months. Apple says iPhone 6 Plus replacement batteries are in short supply and won't be available until late March to early April in the United States and other regions, according to an internal document distributed to Apple Stores and Apple Authorized Service Providers this week and later obtained by MacRumors. Apple's internal document quotes a shorter wait of "approximately two weeks" for iPhone 6 and iPhone 6s Plus battery replacements, and adds that batteries for all other models like the iPhone 6s, iPhone 7, iPhone 7 Plus, and iPhone SE are expected to be available "without extended delays" in most countries. Apple noted that lead times may vary in some regions, including the Middle East, Africa, Latin America, Russia, and Turkey. MacRumors has already received a few emails from readers with an iPhone 6 Plus who were quoted a late March to early April timeframe for the replacement service to be completed at Apple Stores in New York and North Carolina, in line with the information outlined in Apple's document. A reliable source at an Apple Authorized Service Provider indicated that they recently received a package with dozens of replacement batteries, the majority of which were for iPhone 7 and iPhone 7 Plus models. Apple lowered its battery replacement fee to $29 last month for any customer with an iPhone 6 or newer as part of an apology over its lack of transparency about slowing down some older iPhone models to prevent unexpected

U.S. Government Official Questions Apple Over iPhone Battery Slowdowns

Just two days after it emerged a French consumer fraud group is investigating Apple over its handling of battery-related performance issues on iPhones, Apple is now facing questions from government officials in its own country over the controversy. The Wall Street Journal reported on Wednesday that Senator John Thune (R–S.D.), chairman of the Commerce Committee, has sent a letter to Apple CEO Tim Cook asking a series of questions about how the company decided to throttle processing performance in iPhones with older batteries. In a letter to Chief Executive Tim Cook, a copy of which was viewed by The Wall Street Journal, Thune asked how Apple has tracked customer complaints of processing performance, and if Apple has explored offering rebates to customers who paid full price for a battery replacement before the company offered discounted rates last month.In the letter, Thune went on to note that Apple's decision to offer battery replacements at a reduced price had prompted further criticism from customers who believe that Apple should have offered the replacements for free. In addition to the senator's letter, Wednesday's WSJ report included official confirmation from the Paris prosecutor's office that it is overseeing an investigation into Apple's "alleged deception" that is being conducted by French consumer fraud group DGCCRF, which is part of the country's economy ministry. The investigation – which could lead to preliminary charges or be dropped – follows Apple's admission that it slows down some older iPhones with degraded batteries during times of peak

French Consumer Fraud Group Investigating Apple for 'Alleged Deception' and 'Planned Obsolescence'

French consumer fraud group DGCCRF, part of the country's economy ministry, last week launched a preliminary investigation into Apple over "alleged deception" and "planned obsolescence" of Apple products, reports Reuters. The investigation follows Apple's admission that it slows down some older iPhones with degraded batteries during times of peak power usage in order to prevent unexpected shutdowns. Apple introduced the power management feature in iOS 10.2.1 following complaints of unexpected shutdowns in the iPhone 6s, but Apple did not make it clear to consumers that it was due to battery deterioration nor did Apple inform customers that it could cause occasional performance slowdowns. Apple has since apologized for its lack of communication and introduced a new policy that allows iPhone 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus, and SE owners to receive a one-time no-questions-asked $29 battery replacement for their devices, as a device with a depleted battery that is affected by throttling will return to normal performance with a battery replacement. According to Apple, the power management features that prevent unexpected shutdowns by occasionally throttling older iPhones with batteries in bad condition are designed to preserve the life of the iPhone for as long as possible and were not implemented to force upgrades. From Apple:First and foremost, we have never -- and would never -- do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our

Apple Says $29 Battery Replacements Are One-Per-iPhone When Device Passes Diagnostic Test

iPhone users hoping to double dip on Apple's discounted $29 battery replacements this year may find themselves out of luck. While we previously confirmed that Apple is offering $29 battery replacements to any customer with an iPhone 6 or newer regardless of diagnostic result, Apple has indicated that this policy can only be taken advantage of once, according to new fine print on its iPhone service pricing page. In other words, after you've had your iPhone's battery replaced once this year, the device must explicitly fail the diagnostic test to qualify for any additional battery replacements for $29. If the test passes, a customer can still choose to have the battery replaced, but Apple's standard $79 fee applies. Apple says iPhone batteries are designed to retain up to 80 percent of their original capacity at 500 complete charge cycles, and this is likely the primary benchmark for its diagnostic test, but results may vary. While it's unlikely customers would need to have their iPhone battery replaced more than once in a year, some people may have planned on taking advantage of the $29 deal now, and then again near the end of 2018, as the combined $58 cost for two replacements would still be cheaper than the standard $79. Apple reduced the price of iPhone battery replacements as part of its apology over a lack of communication about the power management changes it made starting in iOS 10.2.1. The discount is effective immediately and available worldwide through December 31, 2018. Prices vary outside of the United States. To initiate the process, read our

Apple Now Faces 26+ Lawsuits for 'Purposefully' or 'Secretly' Slowing Down Older iPhones

Apple now faces over two dozen lawsuits around the world that either accuse the company of intentionally slowing down older iPhones, or at least of failing to disclose power management changes it made starting in iOS 10.2.1. The lawsuits include 24 class action complaints in the United States, with the latest two filed on Thursday by Marc Honigman and Lauri Sullivan-Stefanou in New York and Ohio respectively, according to electronic court records reviewed by MacRumors. Apple is also being sued in Israel and France. An excerpt from Sullivan-Stefanou's complaint:Unbeknownst to iPhone 6, iPhone 6 Plus, and iPhone 6s owners, Apple inserted code into iOS 10.2.1 that deliberately slowed down the processing performance of these phones by linking each phone's processing performance with its battery health. Absent the code inserted by Apple, the reduced battery capacity of these phones would not have negatively affected processing performance.Many of the lawsuits demand Apple compensate all iPhone users who have experienced slowdowns, offer free battery replacements, refund customers who purchased brand new iPhones to regain maximum performance, and add info to iOS explaining how replacing an iPhone's battery can prevent slowdowns. The legal action comes after Apple's revelation it may at times dynamically manage the maximum performance of some older iPhone models with chemically aged batteries in order to prevent the devices from unexpectedly shutting down, an issue that can be made worse by cold temperatures or a low charge. Apple never mentioned the power

Apple's $29 Battery Replacement Program Could Lead to 16M Fewer iPhones Sold in 2018

Apple's decision to offer $29 battery replacements to customers with older iPhones could cause iPhone sales to drop in 2018, according to Barclays analyst Mark Moskowitz (via CNBC). Customers opting for a battery replacement instead of upgrading an iPhone could be a "mild headwind" for iPhone unit sales, potentially resulting in millions of fewer iPhone purchases during the year. Moskowitz believes up to 77 percent of iPhone users are eligible to upgrade their batteries. In our base case scenario, 10% of those 519M users take the $29 offer, and around 30% of them decide not to buy a new iPhone this year. This means around 16M iPhone sales could be at risk, creating ~4% downside to our current revenue estimate for C2018.It remains to be seen if and how the battery replacement program will impact sales in practice despite analyst predictions, as there are other considerations that drive upgrades, such as new features. Apple began offering reduced-cost battery replacements following backlash from an admission that it slows down some older iPhone models with degraded batteries to prevent them from shutting down unexpectedly. The power management issue impacts the iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus, but only in situations where battery health has declined. Affected iPhones see throttling during times of peak power usage, such as when running a benchmark. iPhones that are running slower can be restored to their original condition with a fresh battery, which is why Apple has decided to offer $29 replacements

Brazil Demands Apple Explain How iPhone Owners Can Obtain Battery Replacements

Brazilian state agency Procon-SP today asked Apple to better explain why it has implemented power management features in older iPhones and how Brazilian iPhone users can obtain battery replacements, reports Reuters. In a blog post on the Procon-SP website, the agency says that it sent a notice to Apple on Wednesday demanding information on how iPhone customers can replace their batteries, what models are included in the action, how long replacements will be available for, and the cost in Brazil. Image via iFixit Procon-SP attempted to deliver a notice to Apple this morning, which Apple refused to sign, but the demand for information was left at the front desk and the agency is giving Apple 10 days to respond. It is not clear what will happen if Apple does not provide the info, but Reuters says Procon-SP has the power to levy fines or propose legal action against Apple. Apple first announced plans to begin offering reduced-cost battery replacements in late December to provide a fix for customers who have noticed their iPhones slowing down due to power management features impacting older devices with degraded batteries. Initially, Apple said that low-cost battery replacements would be available starting in late January, but later moved the timeline up. In the United States, battery replacements are priced at $29 and are available for the iPhone 6 and newer. Pricing on battery replacements varies in other countries. Customers in need of a battery replacement should contact Apple's support staff in their country to initiate the replacement process. Reduced

How to Get Your iPhone's Battery Replaced at Apple Store or Apple Authorized Service Provider

Apple has reduced the price of battery replacements for the iPhone 6 and newer to $29, down from $79, as part of its apology over a lack of communication about the power management changes it made starting in iOS 10.2.1. The discount is effective immediately and available until the end of 2018. iPhone users in most countries can initiate the battery replacement process online by scheduling an appointment with the Genius Bar at an Apple Store. The reduced price is also available at some third-party retailers and repair shops, as long as they are designated as an official Apple Authorized Service Provider. After this article was published, MacRumors received a tip claiming Apple has reduced the price it charges Apple Authorized Service Providers for iPhone batteries to $5, down from $55, but some repair shops are still charging more than $29 for replacements to maintain reasonable profit margins for time and labor.

FAQ: What to Know About Apple Slowing Down iPhones to Prevent Unexpected Shutdowns

By now, you've probably seen headlines about Apple slowing down your iPhone, but it's not nearly as simple or corrupt as it sounds. In this Q&A, we've taken the time to explain exactly what's going on. Why is Apple slowing down some older iPhone models? iPhones, like many other consumer electronics, are powered by lithium-ion batteries, which have a limited lifespan. As the battery in your iPhone ages, its ability to hold a charge slowly diminishes. A chemically aging battery can also have increased impedance, reducing its ability to provide a sudden burst of power when demanded by other components in an iPhone, such as the CPU and GPU. A battery's impedance will also temporarily increase when it has a low charge and/or in cold temperatures. A battery with a high enough impedance may be unable to provide power quickly enough to the iPhone when needed, and Apple safeguards components against the drop in voltage by shutting down the device. Apple recognized that iPhones unexpectedly shutting down on users is not a good experience, and starting with iOS 10.2.1, it quietly implemented a power management feature to prevent these shutdowns. The update was released in January 2017, and a month later, Apple said it saw a major reduction in shutdowns. How does Apple's power management feature work? Apple says it looks at a combination of an iPhone's internal temperature, battery percentage, and battery impedance, and only if a certain criteria is met, iOS will dynamically manage the maximum performance of some system components, such as the CPU and GPU, in order

Apple Will Replace the Battery in Your iPhone 6 or Later Even if It Passes a Genius Bar Diagnostic Test

Last week, Apple reduced the price of out-of-warranty iPhone battery replacements from $79 to $29, following a wave of controversy over power management features in older iPhones. In a note to customers, Apple said its new policy applied to "anyone with an iPhone 6 or later whose battery needs to be replaced", but failed to specify if this eligibility criteria was dependent on whether a given iPhone failed an official Genius Bar diagnostic test. This morning, French tech blog iGeneration reported that an internal Apple Store memo has been circulated which states that if a customer asks for a battery replacement on an iPhone 6 or later, then the Genius Bar should allow it, even if their phone passes Apple's own diagnostic test. Apple has since independently confirmed to MacRumors that it will agree to replace an eligible battery for a $29 fee, regardless of whether an official diagnostic test shows that it is still able to retain less than 80 percent of its original capacity. The concession appears to have been made to mollify the anger of customers stoked by headlines suggesting that Apple artificially slows down older iPhones to drive customers to upgrade to newer models. Anecdotal reports also suggest that customers who paid $79 to have their battery replaced before the new pricing came into effect on Saturday, December 30, will receive a refund from Apple upon request. Please let us know of your own experiences in the comments below. Apple last week was forced to apologize over a lack of transparency regarding its process of dynamically managing the peak

Apple Makes $29 Battery Replacements Available Immediately for iPhone 6 and Newer

Apple today announced it is making its reduced $29 battery replacements available immediately for iPhone 6 and all newer models. Apple previously said it would offer the cheaper battery replacements in late January, but it has removed that timeframe from its letter to customers, and has confirmed immediate availability in a statement to TechCrunch.We expected to need more time to be ready, but we are happy to offer our customers the lower pricing right away. Initial supplies of some replacement batteries may be limited.Apple normally charges $79 for out-of-warranty iPhone battery replacements, but it reduced the price by $50 following a wave of controversy over its process of dynamically managing the peak performance of some older iPhone models with degraded batteries to prevent unexpected shutdowns. Given a lack of nuance in some mainstream coverage, many headlines have fueled speculation that Apple artificially slows down older iPhones to drive customers to upgrade to newer models, but the actual issue was Apple's lack of transparency about the power management changes it made starting in iOS 10.2.1. When it released iOS 10.2.1 in February, Apple only vaguely said it made "improvements" to reduce occurrences of unexpected shutdowns. It only chose to explain that the changes it made may result in temporary slowdowns on some older iPhone models with degraded batteries after controversy recently reignited. The issue came into the spotlight in early December after a Reddit user claimed that his iPhone's performance significantly increased after replacing the
