Following the release of the new iOS 26 update, Apple users are reporting various issues. A common complaint is significant battery drain after the update’s installation. These issues are widespread across various online platforms.
Reports of the problems began appearing immediately after the update was made available.
Several users have detailed their experiences. One user observed their battery level dropping from full to 79% in a short period. Others have reported a noticeable decrease in their phone’s battery health since the update.
Further complaints involve phones running hotter than usual and exhibiting performance lags when rendering animations. Apple had advised users of potential temporary impacts on battery and thermal performance after installation.
A number of users on Reddit have reported similar issues. One user mentioned the indexing of a large number of items as a possible cause for increased heat. Some users suggest that Apple may have anticipated these thermal issues, citing the vapor chamber cooling systems in the new iPhone 17 models.
Although Apple has previously acknowledged the impact of software updates on battery life, the current level of post-update battery drain has not been explicitly addressed by the company before.
