If the installation of iOS 26 is causing your iPhone's battery to deplete, Apple indicates this is a temporary issue.
Apple has announced the release of its latest operating system, iOS 26, at the Worldwide Developers Conference in June. The update, which became available on September 15, includes new features such as call screening and a Liquid Glass redesign.
Upon downloading iOS 26, users might notice a temporary impact on battery life and thermal performance. Apple has addressed this issue on their website, explaining that the temporary battery drain is due to the device needing time to complete the setup process, including indexing data and files for search, downloading new assets, and updating apps.
Some users have reported a faster battery drain after downloading the update, which Apple says is temporary and normal. The company has issued instructions to fix a possible temporary battery loss, and users are advised to follow these steps to ensure their devices return to normal battery performance as soon as possible.
It is important to note that using the iPhone more after downloading iOS 26 could also contribute to battery drain. Some new features in iOS 26 might require more resources, potentially causing a small impact on performance and battery life. However, Apple expects the additional battery drain to be temporary.
Despite the temporary battery drain and thermal performance impact, users do not need to worry about the update. The new features and improvements offered by iOS 26 are expected to enhance the overall user experience. As with any major update, it is recommended to backup your data before installing iOS 26 to ensure your information is safely stored.
