Apple has announced that on Monday, September 9 it will hold its annual fall event, which means we are just days away from the launch of the iPhone 16. Like the iPhone 15 series, this year's lineup is expected to stick with four models – iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max – although there are plenty of design differences and new features to take into account.
To bring you up to speed ahead of Apple's "It's Glowtime" event, we've summarized below the biggest iPhone 16 rumors we've covered so far here on MacRumors. For more details, follow the links, or dive into our dedicated roundups for both iPhone 16 and iPhone 16 Pro models.
1. Larger Displays
Biggest Ever iPhones
This year's iPhone 16 Pro and iPhone 16 Pro Max are rumored to be getting bigger display sizes, increasing to 6.27- and 6.86-inches, respectively. For comparison, the iPhone 15 Pro and iPhone 15 Pro Max are equipped with 6.1-inch and 6.7-inch displays, respectively. The new display sizes would be the largest ever for the iPhone.
2. Vertical Camera Layout
iPhone 16 & iPhone 16 Plus
Apple's iPhone 16 base models will feature a vertical camera arrangement with a pill-shaped raised surface, instead of a diagonal camera arrangement like the iPhone 15. The new camera bump features two separate camera rings for the Wide and Ultra Wide cameras. The vertical camera layout is expected to enable Spatial Video recording, which is currently limited to the iPhone 15 Pro models.
3. Battery Changes
All iPhone 16 Models
Rumors suggest the iPhone 16 and iPhone 16 Pro Max will feature larger batteries than their predecessors, although the smaller iPhone 16 Pro device could see the biggest improvement, while the iPhone 16 Plus may have reduced capacity. The iPhone 16 is said to have a 6% increase over the iPhone 15, with the iPhone 16 Pro Max gaining a 5% increase, and the iPhone 16 Pro seeing a 9% increase. In contrast, the iPhone 16 Plus is rumored to have a 9% reduction in capacity. On the other hand, Apple could also potentially use stacked battery technology to increase energy density and prolong lifespan across the lineup.
4. Capture Button
New Camera Capabilities
All iPhone 16 models will have a new "Capture Button" dedicated to triggering image or video capture. The button will add features like the ability to zoom in and out by swiping left and right on the button, focus on a subject with a light press, and activate a recording with a more forceful press. The Capture Button will be located on the bottom right side of the iPhone 16, and will take the place of the mmWave antenna on U.S. iPhone models, with the antenna relocating to the left side of the device below the volume and Action buttons.
5. Ultra Wide Lens Upgrade
iPhone 16 Pro & iPhone 16 Pro Max
The iPhone 16 Pro models are expected to feature an upgraded 48-megapixel Ultra Wide camera lens, which should allow it to capture more light, resulting in improved photos when shooting in 0.5× mode, especially in low-light environments. This also means that iPhone 16 Pro models should be able to shoot 48-megapixel ProRAW photos in Ultra Wide mode. These photos retain more detail in the image file for more editing flexibility, and can be printed at large sizes. The iPhone 16 Pro Max is also rumored to boast a bigger main camera thanks to an advanced custom 48-megapixel Sony IMX903 sensor.
6. Super Telephoto Camera
iPhone 16 Pro Max
The iPhone 16 Pro Max could be the first to feature a super telephoto periscope camera for dramatically increased optical zoom. "Super" or "ultra" telephoto usually describes cameras with a focal length of over 300mm. The current telephoto lens is equivalent to a 77mm lens, so if accurate, there could be a notable increase in zoom capabilities. Super telephoto cameras are often used for sports and wild animal photography, but the extremely soft backgrounds they create also make them useful for portrait photography, providing there is enough distance between the subject and the photographer.
7. Faster Wi-Fi Support
Wi-Fi 6E & Wi-Fi 7
Apple's 2024 iPhone Pro models are expected to get Wi-Fi 7 in the Pro models, enabling data transfer over the 2.4GHz, 5GHz, and 6GHz bands simultaneously. This should result in faster Wi-Fi speeds, lower latency, and more reliable connectivity. With technologies such as 4K QAM, Wi-Fi 7 is also expected to offer peak data transfer speeds of over 40 Gbps, a 4× increase over Wi-Fi 6E. Meanwhile, the iPhone 16 and iPhone 16 Plus is rumored to support Wi-Fi 6E, which works with the 6 GHz band, enabling faster wireless speeds and reduced signal interference.
8. New A18 Series Chips
All iPhone 16 Models
Apple's next-generation A18 Pro chip is expected to be manufactured with TSMC's second-generation 3nm process, known as N3E. All four iPhone 16 models will be equipped with A18-branded chips, according to rumors, but Apple could still differentiate between the standard models and the Pro models, even giving the chips separate A18 and A18 Pro names. It makes sense for all four iPhone 16 models to have the same A18 chip because of the Apple Intelligence features set to debut in iOS 18. Apple Intelligence requires a high-powered chip for the AI features to run on-device. At this time, only the iPhone 15 Pro and Pro Max are able to use Apple Intelligence.
9. 5G Qualcomm Modem
iPhone 16 Pro & iPhone 16 Pro Max
Apple is expected to use Qualcomm's latest Snapdragon X75 modem in this year's Pro and Pro Max models. The Snapdragon X75 includes improved carrier aggregation and other technology advancements for faster 5G download and upload speeds compared to the X70, which is used in iPhone 15 models. The modem's combined mmWave and sub-6GHz 5G transceiver also takes up 25% less circuit board space, and is said to use up to 20% less power. The standard iPhone 16 and iPhone 16 Plus are expected to retain the Snapdragon X70 modem.
10. Tetraprism Lens
iPhone 16 Pro
Both iPhone 16 Pro models are expected to feature 5x optical zoom, which is currently exclusive to the iPhone 15 Pro Max. Apple's tetraprism lens system has a "folded" design that allows it to fit inside the smartphone, enabling up to 5x optical zoom and up to 25x digital zoom. In contrast, the current smaller iPhone 15 Pro is limited to up to 3x optical zoom, which is in line with the iPhone 14 Pro and iPhone 14 Pro Max.
11. Micro-Lens Technology
More Efficient OLED
Apple is said to be weighing up the use of micro-lens technology to maintain or increase the brightness of OLED displays on next year's iPhone 16 models while potentially reducing their power consumption. MLA works by using a uniform pattern of billions of lenses inside the panel that reduces internal reflections. These lenses turn the path of light reflected backwards from the inside of the panel towards the screen, which can serve either to increase perceived brightness while maintaining the same level of power consumption, or maintain brightness levels while consuming less power compared to conventional OLED panels at the same luminance.
12. Action Button
iPhone 16 & iPhone 16 Plus
The iPhone 15 Pro models include an Action Button, and in 2024, the Action Button is expected to be expanded to the standard iPhone 16 models. The Action Button used across the iPhone 16 lineup will be identical to the iPhone 15 Pro Action Button. The Action button, which replaces the traditional mute switch, can perform multiple functions such as activating the Flashlight, turning on the Camera, launching a Shortcut, enabling or disabling a Focus mode, using Translate, turning on/off Silent Mode, and more.
13. 40W Fast Charging and 20W MagSafe
Both iPhone 16 Pro Models
The iPhone 16 Pro and iPhone 16 Pro Max will support 40W wired fast charging and 20W MagSafe charging, according to a recurring rumor. Right now, iPhone 15 and iPhone 15 Pro models are capable of up to 27W peak charging speeds with an appropriate USB-C power adapter, while official MagSafe chargers from Apple and authorized third parties can wirelessly charge the iPhone 15 models at up to 15W. The charging boost is expected to balance and improve the problem of increasing charging time caused by the increase in battery capacity.
14. Upgraded Microphone
Enhanced Siri
Apple is said to be planning a significant upgrade to the iPhone 16 microphone to improve the new Apple Intelligence-enhanced Siri experience, which will include contextual awareness, semantic indexing, app control, and on-screen awareness. Apple's Siri AI ambitions will heavily rely on improved voice input processing, and the new mic is expected to offer significantly enhanced signal-to-noise ratio.
15. New Thermal Design
Reduced Heat
Apple is rumored to be working on a graphene thermal system for the iPhone 16 lineup, while the iPhone 16 Pro models could add metal battery casings to reduce overheating. Graphene has high thermal conductivity, surpassing that of copper, which is currently used in iPhone heat-sinks. Another source has claimed that iPhone 16 models will be equipped with a "larger graphite sheet" inside the chassis of the devices, to address potential overheating. The move could be in response to widely encountered overheating issues experienced with the iPhone 15 Pro, which Apple addressed through a software update.
16. Expanded Storage
Both iPhone 16 Pro Models
The iPhone 16 Pro and iPhone 16 Pro Max will be available with double the maximum storage capacity as the iPhone 15 Pro models, increasing from 1TB to 2TB, according to one rumor. The move is said to be a result of Apple's switch to higher-density Quad-Level Cell (QLC) NAND flash for higher storage models. Apple's use of QLC NAND could allow Apple to fit more storage into a smaller space and it is less expensive than Triple-Level Cell (TLC) NAND, which current iPhones use. On the downside, QLC has comparatively slower read and write speeds.
17. Increased Memory
iPhone 16 & iPhone 16 Plus
Apple's iPhone 16 and iPhone 16 Plus models have been rumored to both feature 8GB of RAM, an increase over the 6GB of RAM in the iPhone 15 and iPhone 15 Plus. More working memory should equate to improved performance for multitasking on the iPhone. Apple has hinted that plenty of RAM is required for Apple Intelligence features, so it is perhaps no coincidence that all devices in the iPhone 16 lineup will have at least 8GB of RAM.
18. Upgraded Neural Engine
Enhanced Machine Learning
Apple's next-generation A18 chips will feature an upgraded Neural Engine with "significantly" more cores, according to one Taiwanese report. An upgraded Neural Engine should improve the performance of Apple Intelligence features and machine learning tasks. Apple's iPhone 12 through iPhone 15 models all include a 16-core Neural Engine. Despite no difference in core counts across generations, Apple has still managed to improve their performance in successive models.
19. Ultra-Thin Bezel Technology
Maximized Display Size
Apple plans to maximize the display size on the iPhone 16 series by using a new ultra-thin bezel technology, according to one rumor. Apple will use Border Reduction Structure (BRS) technology to minimize the bezel at the bottom of the display. BRS achieves this by rolling up the internal copper wiring into a more compact package. Apple reportedly plans to apply the borderless display technology to all four iPhone 16 models, but the Pro models will have the thinnest bezels of any smartphone, beating the screen border thinness of even its latest iPhone 15 Pro devices.
20. New Polished Titanium Finish
iPhone 16 Pro & iPhone 16 Pro Max
Apple will use an improved finishing process for the titanium chassis on the iPhone 16 Pro models, according to one rumor. The new process will allegedly make the iPhone 16 Pro and iPhone 16 Pro Max look more polished than the iPhone 15 Pro models, which have a brushed finish. The improved manufacturing process will result in a glossy appearance that is more akin to the heavily polished stainless steel material used in previous Pro iPhones. However, the new titanium finish will be less prone to scratches compared to stainless steel.
21. Reduced Lens Flare
Less Photo Artifacts
Apple is said to be testing a new anti-reflective optical coating technology for its iPhone cameras that could improve the quality of photos by reducing artifacts like lens flare and ghosting. Apple plans to bring new atomic layer deposition (ALD) equipment into the iPhone camera lens manufacturing process to apply the coating. ALD-applied materials can also protect against environmental damage to the camera lens system without affecting the sensor's ability to capture light effectively.
22. New Colors
All iPhone 16 Models
The iPhone 16 Pro and iPhone 16 Pro Max are expected to be available in black, white or silver, gray or "Natural Titanium," and rose. This suggests that the iPhone 15 Pro's Blue Titanium option will be discontinued and replaced with a new rose or rose gold titanium color, which could even have a bronze appearance under certain lighting conditions. Meanwhile, the iPhone 16 and iPhone 16 Plus is said to be coming in black, green, pink, blue, and white. Compared to the iPhone 15, this means that white will replace yellow, with the other colors remaining the same.
23. 256GB Base Storage
Smaller iPhone 16 Pro Model
Apple is expected to offer both the iPhone 16 Pro and iPhone 16 Pro Max with a minimum of 256GB storage, doing away with the 128GB starting option on its smaller Pro model for the first time, according to TrendForce. Currently, Apple's 6.1-inch iPhone 15 Pro starts at $999 and comes with the minimum 128GB of storage, while the 6.7-inch iPhone 15 Pro Max starts at $1,199 with a minimum 256GB of storage. Ahead of the launch of the iPhone 15 models, there were rumors that the iPhone 15 Pro Max could start at $1,199, instead of the $1,099 starting price it charged for the iPhone 14 Pro Max. That did turn out to be accurate, but only because Apple eliminated the lower priced 128GB storage tier. The iPhone 15 Pro Max now starts at 256GB, and $1,199 is the same price Apple charged for the 256GB iPhone 14 Pro Max. TrendForce believes Apple will follow the same strategy for the iPhone 16 Pro model to cover the added cost of the new periscope lens coming to the iPhone 16 Pro.
Are you looking forward to the iPhone 16 series and plan to upgrade, or are you skipping this year's model?
