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.

Pixel 11 Pro Fold vs. Galaxy Z Fold 8 Ultra: Google plays it safe, Samsung goes all-in
Two expensive foldables, two very different takes on what your phone should actually do.
Electronics, Phone, Mobile Phone

Even though both Google and Samsung agree that a book-style foldable can replace your tablet while still retaining the best characteristics of a conventional flagship smartphone, they've built two very different machines to prove it. 

The Pixel 11 Pro Fold leans on Google's software intelligence and a genuinely rare durability rating, while the Galaxy Z Fold 8 Ultra leans on raw silicon, a 200MP camera, and Samsung's most mature multitasking software yet. So, which one is better for you? Let’s figure it out in this detailed comparison between the two.

I went hands-on with the Pixel 11, and Google’s cheapest flagship finally has it all
The Pixel 11 finally gives me almost everything I want from a base flagship
Electronics, Mobile Phone, Phone

Looking at any premium smartphone lineup, it's immediately clear that the love, care, and attention went towards the Pro or Ultra models. Base flagship models always have to hit a balance between being approachable and feeling premium. Apple's iPhone 17 was a great example of this, while the Galaxy S26 was another solid option (despite its various flaws).

Google, on the other hand, felt a little behind the competition with the Pixel 10. So during the short time with the Pixel 11, I expected that same reputation--and thankfully, the latest standard Pixel device is more competitive than ever before.

Scammers have been targeting WhatsApp users for years, and the numbers prove it. The FTC says victims reported losing $425 million to scams on WhatsApp alone, part of a broader $2.1 billion lost to social media scams in 2025.

Now Meta is fighting back with Scam Alert, a new optional feature rolling out in limited beta that flags suspicious messages using artificial intelligence, all without ever reading your actual conversations.
