With iOS 26, Apple is launching a major software update for iPhones and iPads. In addition to new features like Liquid Glass and improved multitasking, the company also reports some limitations. Right after installing iOS 26, battery life may noticeably decrease.
On September 15, 2025, Apple initiated the next wave of updates. Alongside iOS 26 for iPhones, iPadOS 26 and watchOS 26 were also released. Millions of users are downloading the software to test innovations like the Liquid Glass design, optimized multitasking, and numerous detailed improvements. However, the excitement over the new features in iOS 26 is tempered by one drawback: battery life.
Shortly after installation, users report a noticeably higher energy consumption. Some devices also generate more heat than usual. Apple has now officially confirmed these observations.
Reduced Battery Life from iOS 26 Only Temporary
In a support document, Apple explains that reduced battery life after major updates is normal. The reason is background processes such as re-indexing data, loading system files, and updating apps. These operations require additional energy and can take some time.

It states that immediately after a major update, battery life and heat generation may be affected. Once these processes are completed, the situation usually normalizes.
New Features Demand More Energy
Apple also acknowledges that some of the new features inherently require more power. However, the company emphasizes that the impact on energy consumption is limited and largely depends on usage behavior.
Those concerned about battery life do not need to switch to iOS 26 immediately. Staying with iOS 18 is still an option. Many experienced users are waiting for the first bug-fix updates, which Apple traditionally releases a few weeks after launch. These usually bring stability improvements and optimized battery performance.
