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 next iPhone SE, set for a 2025 market arrival, is shaping up to be one of the most interesting smartphones Apple has offered in years. But it seems there’s also a Plus-sized blockbuster planned for next year.

Japanese website Macotakara has shared images of what it claims to be the “3D printed mockup” of the upcoming iPhone SE. Once again, we are greeted by a familiar design that is nigh identical to the iPhone 14, something that has also been reported by Bloomberg.

Do you feel like your battery life has worsened since upgrading to iOS 18? If so, you aren't alone. Dozens of users are reporting excessive amounts of battery drain, specifically on the iPhone 16 and iPhone 16 Pro. But is there a fix? Unfortunately, not yet.

According to MacRumors, there's a long-running thread with hundreds of posts from users lamenting their battery's lack of joie de vivre. One user said their phone drops from 100% charge to 60% by midday, even though there was no heavy usage during that time. Another user reported a battery drain of around 1% every five minutes. Obviously, this isn't a great look for Apple.

Photographic Styles is the best iPhone feature I’ve used in years

What makes a good photo? For the average person, anything with tons of punchy colors and sharp lines that can elicit some envy-filled comments on social media is good enough. A few would argue that you need reality in a picture, perfect or otherwise, and not a saturated, computationally generated mess.

I recently spent $20 on the Halide app to find out what an AI-free, computation-free picture looks like. The results from the aptly named Process Zero were a revelation. But as any photographer would tell you, a camera is only as good as the hands using it.
