Apple recently released its latest major software update, iOS 26. While the update includes new features like call screening and Liquid Glass redesign, many users are experiencing battery drain and slowdown after installing it.
Since iOS 26’s release at the beginning of this week, iPhone owners have reported their batteries depleting rapidly—some within just a few hours. Social media is filled with complaints, and some users are reporting screen lags, app freezing, and difficulty using the new design. Apple has addressed these issues and explained why they persist.
According to Apple’s statement on its support page, iPhone users experiencing worse performance after the update should not be surprised. A major OS update demands intensive background tasks, including file indexing, data reorganization, and optimization. These processes put extra strain on the battery, making devices feel slower and hotter than usual.
Apple also noted that new features require more resources, leading to increased power consumption and sluggish phones. While these issues typically resolve within a few days, some users continue to report permanent battery life compromise due to more demanding features in iOS 26.
Despite Apple’s explanations, many remain frustrated, believing such issues should be resolved before the update is released. Users expect their devices to perform better or at least the same after upgrading, not worse. As complaints persist, many suggest waiting for the iOS 26.1 update before installing.
It’s normal for some glitches to arise after an update, and waiting a few weeks to assess performance would be a more prudent approach.
