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 today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name.
The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

With just three days to go until the iPhone Duo is released, Apple is getting ready for the launch. Behind the scenes, the App Store now has screenshots of Apple's built-in apps running on the Duo. We've seen some apps in marketing materials, but images of the ones we haven't seen give us an idea of what it will be like using the iPhone Duo day to day.
Many apps are shown in landscape...

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.geekwebguides.com/2024/06/12/ios-18-charging-limit-recommendations/') * Additional charging limit options ('https://www.geekwebguides.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 A16 chip6GB RAMDynamic Island USB-C port that's needed to enable the feature? 🤷♂️
