iOS 26.1 Update Causing Temporary Battery Drain, Apple Says
Apple released iOS 26.1 yesterday, and users are reporting temporary increased battery drain following the update, a phenomenon Apple has acknowledged as normal.
The company stated that immediately after a major iOS release, devices require time to complete background processes such as data indexing, file downloading, and app updates, which can temporarily impact battery life and thermal performance. This is a common occurrence after significant software updates, as the system re-optimizes itself for new features and functionalities. Apple initially addressed this issue in a statement released in September, anticipating user concerns.
According to Apple’s support page, “This is normal, as your device needs time to complete the setup process in the background…Immediately after completing an update, particularly a major release, you might notice a temporary impact on battery life and thermal performance.” The company also notes that increased usage of new features within iOS 26.1 could also contribute to higher battery consumption.

While some battery drain is expected, Apple assures users the issue should resolve itself as the background processes complete. This update arrives as consumers increasingly rely on their smartphones for daily tasks, making battery performance a critical factor in user experience. Users experiencing persistent battery issues beyond the initial period are encouraged to consult Apple’s support resources or visit an Apple Store.
Apple released iOS 26.1 on Monday, and the update brings a few new settings to your iPhone, like another way to adjust the Liquid Glass on your device. If you downloaded the update and noticed your device’s battery is draining faster than usual, Apple wrote online that it’s normal and — most important — temporary.
Some people notice their iPhone battery drains quickly after downloading an update, and Apple released a statement in September saying it’s nothing to worry about.

“This is normal, as your device needs time to complete the setup process in the background, including indexing data and files for search, downloading new assets, and updating apps,” Apple wrote in a support page. “Immediately after completing an update, particularly a major release, you might notice a temporary impact on battery life and thermal performance.”
But your personal iPhone usage could contribute to battery drain. Apple said some features might need more resources to function, so depending on how much you use your iPhone, you might “notice a small impact on performance and/or battery life.”
So while your device might experience some additional battery drain at first, it should be a temporary issue after you download iOS 26.1. If you find you’re using your iPhone more after downloading iOS 26.1, that could be contributing to your battery drain, too.
