The iPhone has had a Power Reserve function that holds back a small amount of battery life to allow features like Find My and NFC unlocking to work even when your device has died, and in iOS 18, Apple seems to be improving the feature further for the iPhone 15 models.
As demonstrated on Reddit, when the battery on an iPhone running iOS 18 is exhausted, the phone can continue to show the time in the upper left corner of the device, which is a small but useful upgrade. The battery icon still shows up, and you'll see "iPhone is Findable" while reserve battery is left.
It appears that this feature is limited to the iPhone 15 models. We tested on an iPhone 14 Pro Max and were not ale to get the time to show up, but it did work as expected with an iPhone 15 Pro Max.
Power Reserve has been a feature on iPhones dating back to the iPhone XR and iPhone XS, so it's not clear what the limiting factor is in terms of showing the time on display when the battery has drained on older devices.
Apple's iPhone 17 Pro and iPhone 17 Pro Max models will feature a number of significant display, thermal, and battery improvements, according to new late-stage rumors.
According to the Weibo leaker known as "Instant Digital," the iPhone 17 Pro models will feature displays with higher brightness, making it more suitable for use in direct sunlight for prolonged periods. The iPhone 16 Pro and...

Because iPhone sales have been slowing down and people are keeping their iPhones longer and longer, Apple is becoming more and more aggressive in creating artificial restrictions to get users to upgrade - this is a classic example. The author even pointed this out in their article - "Power Reserve has been a feature on iPhones dating back to the iPhone XR and iPhone XS, so it's not clear what the limiting factor is in terms of showing the time on display when the battery has drained on older devices."
If you want further proof, look no further than these examples:
* Adaptive Charging limit ('https://www.macrumors.com/2024/06/12/ios-18-charging-limit-recommendations/') * Additional charging limit options ('https://www.macrumors.com/2024/06/10/ios-18-introduces-more-charging-limits/') * Apple Intelligence compatibility is restricted to iPhone 15 Pro and later (however, this also could be due to the increased RAM that are in these devices)

Maybe the reason none of the prior iPhone models have this exclusive to iPhone 15 series feature is because none of them have [s]A16 chip[/s] [s]6GB RAM[/s] [s]Dynamic Island[/s] USB-C port that's needed to enable the feature? ?♂️
Biggest design overhaul since iOS 7 with Liquid Glass, plus new Apple Intelligence features and improvements to Messages, Phone, Safari, Shortcuts, and more. Developer beta available now ahead of public beta in July.
