Some iPhone 16 and iPhone 16 Pro owners are experiencing battery life problems after upgrading to iOS 18. Users have raised concerns on forums like MacRumors, Reddit, and Apple’s support pages, reporting that their phones seem to lose battery power even while in standby mode. This suggests that background activity could be causing the battery to drain unexpectedly. However, because different applications consume power at varying rates, it’s difficult to quantify how much battery life is typically lost in standby mode.
What’s Happening & Why This Matters
The iPhone 16 boasts a larger battery compared to its predecessor, with a capacity of 3561mAh — 6.3% larger than the iPhone 15. In tests, the iPhone 16 showed improved battery life, lasting 17 hours and 47 minutes compared to the iPhone 15’s 16-hour battery life. Yet, despite this improvement, some users are reporting that their devices are draining quickly even when they are not actively using them.
Users on older iPhone models who upgraded to iOS 18 are also encountering similar battery drain issues. However, some have found that upgrading to iOS 18.0.1 or the iOS 18.1 beta helped resolve the problem. The general consensus suggests that a forthcoming update, iOS 18.1, which is scheduled to release on October 28, may include a fix for this issue.
Although Apple has not yet issued an official statement about the battery drain, iOS 18.0.1 has already addressed various bugs, including problems with the touch screen, app crashes, and memory management issues.
TF Summary: What’s Next
As users await the official release of iOS 18.1, which may resolve battery performance concerns, many are hopeful that Apple will address the root cause of the battery issues. For now, users facing these problems can either try updating to iOS 18.0.1 or sign up for the iOS 18.1 beta, both of which have reportedly fixed the problem for some users.
