While it's not a huge update, it does feature some important bug fixes for various iPhone 17 and iPhone Air models, so it's worth installing at your earliest opportunity. We covered the intermittent Wi-Fi and Bluetooth issues last week, which were causing users of the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air to lose active connections when unlocking their handsets. Google Pixel 10 owners have been reporting wireless charging problems with older chargers, for example. There's also a new iOS 18.7.1 update for older iPhones that don't support iOS 26 (that's anything before the iPhone 11 basically). However, these software upgrades can't do anything for your iPhone if you're seeing an excessive amount of scratching.
