Apple has officially acknowledged a battery drain issue affecting iPhones after the recent iOS 26 update. Many users reported faster battery depletion and sluggish performance following the update. According to Apple, this is a temporary effect caused by background processes such as indexing and app updates that run after installing a major iOS upgrade.
Why Is Your iPhone Battery Draining Faster?
After updating to iOS 26, your device re-indexes files, updates apps, and optimizes system performance. These background activities temporarily consume more power, which might make it seem like your battery life has taken a hit. Usually, this extra drain lasts for a couple of days while your iPhone completes these tasks.
What Can You Do?
Apple recommends giving your iPhone a few days to finish these processes. Battery performance should return to normal after that. In the meantime, you can minimize battery use by reducing screen brightness, disabling unnecessary background app refresh, and closing unused apps. If the problem persists for more than a few days, consider restarting your device or checking for additional updates from Apple.
