iOS 18 has a hidden feature you’ll only see when your iPhone battery dies

It’s been just a few days since Apple released the first developer preview of iOS 18. Since then, developers and everyday users have discovered features in the first iOS 18 beta that Apple didn’t mention in its Worldwide Developers Conference (WWDC 2024) keynote. The most recent discovery concerns what happens when your iPhone’s battery becomes exhausted.

Apple iPhones have a power reserve feature that conserves a small amount of battery life to support essential functions like Find My and NFC unlocking when the battery is nearly depleted. In iOS 18, the feature appears to be extended.

According to a Reddit post, even when the battery is drained, your iPhone will continue to display the time in the upper-left corner of the screen. You’ll also see a message on the screen that notes, “iPhone is Findable,” as well as a depleted battery icon.

MacRumors says the new feature only works on the iPhone 15 and, undoubtedly, the upcoming iPhone 16 series. This limitation is strange given that iPhones back to the iPhone XS have had power reserve functionality. Regardless, it’s nice to discover tiny new features in iOS betas.

Earlier this week, we noted that iOS 18 offers a redesigned iPhone flashlight that allows you to make the flashlight beam wider or narrower. There are also plenty of new home screen customization features — some good and some bad.

No doubt, much more about iOS 18 will be discovered and discussed during beta testing. This process will likely be extended into September when new iPhones are announced and the first public version of iOS 18 arrives.

Apple officially announced iOS 18, iPadOS 18, macOS Sequoia, watchOS 11, and visionOS 2 earlier this week. Apple Intelligence will be the most significant update for each of these software updates and their devices. This AI technology from Apple is expected to revolutionize how we interact with our devices by impacting writing, image creation, and search. Siri will also undergo significant changes as part of the Apple Intelligence update.

The iPhone 16 might be a bigger upgrade than we thought

The iPhone 16 is due for some big upgrades if the latest rumors are to be believed. According to CTEE (per AppleInsider), Apple is planning on putting the latest and greatest A18 chip in both the iPhone 16 and iPhone 16 Pro models, which would close the performance gap that’s typically existed between devices in the lineup. This is a significant and fairly positive change for people who usually buy the base or Plus model due to cost reasons.

Sources also claim that Apple has upped its chip order from TSMC, its main supplier. The company is anticipating selling between 90 million and 100 million units of the iPhone 16, a step up from the 80 million to 90 million iPhone 15 and iPhone 15 Pro units it sold last year. If true, this would be a significant departure from what Apple has done in previous generations.

It’s been years since the iPhone 7 was released in 2016, but the class action lawsuit against Apple over audio issues has finally worked its way through the courts, resulting in a $35 million settlement. The good news is that if you weren’t aware of this settlement and you are an iPhone 7 or iPhone 7 Plus owner, you may still be able to claim the settlement money.

The original deadline for the settlement was June 3, 2024, but the United States District Court for the Northern District of California revised it to July 3, 2024, for unknown reasons.
