The iPhone 17.0.3 update has just been released, and most of the attention has been on how it’s designed to stop the iPhone 15 Pro from overheating. But Apple has just confirmed that the update helped fix another bug that was causing iPhone batteries to drain far too quickly. A bug that is all the watchOS 10.1 beta’s fault.

According to Apple, users may have noticed “increased power consumption” if an Apple Watch running the beta was paired with an iPhone running the final version of iOS 17 — rather than the iOS 17 beta. Apparently the problem could also occur with an iPhone running the iOS 17.1 beta and the final version of watchOS 10.

Apple’s also tweaking the Action button on iPhone 15 Pro, with the aim of trying to avoid unwanted triggers when the phone is in your pocket. Obviously there are no settings for that, but it means you won’t accidentally switch on the flashlight or switch the phone out of silent mode without realizing it.
