With iOS 26, Apple has released a new version of the iPhone operating system. In addition to improvements and new features, the company points out potential impacts of installing the update in the official release notes. Immediately after the update, battery life may temporarily appear shorter and the device's thermal performance may fluctuate. According to Apple, this is normal behavior.
After major iOS updates, there are regular discussions about perceived deterioration in battery life. This topic has resurfaced with iOS 26. To avoid misunderstandings, Apple has created a support document explaining why software updates can affect power consumption and why this isn't a permanent problem. While the document applies generally to iOS and iPadOS versions, Apple has highlighted it in the iOS 26 release notes.
Background processes after an update
Immediately after installing iOS 26, the iPhone starts various background tasks. These include indexing data and files for search, downloading new system assets, and updating apps. These processes ensure the device can operate efficiently and utilize new features. During this phase, energy consumption increases, which can be noticeable in reduced battery life. Increased heat generation is also possible while these tasks are running in the background.

Impact of new features on battery life
An update like iOS 26 brings not only optimizations but also additional features. These sometimes require more resources than previous versions. This can slightly impact performance or battery life. Depending on individual usage, this difference may be barely noticeable or significantly more noticeable. Apple emphasizes that hardware and software are perfectly matched and are continuously improved through further updates.
Transparency through a new support document
Apple is more transparent about battery life with iOS 26. While previous support documents have also indicated potential increased battery consumption after updates, this time the company is presenting this information with even greater clarity. Complaints about decreased battery life after an update are widespread, which is why Apple is now explaining the connection in more detail. The note in the iOS 26 release notes is intended to help better understand expectations.
Why updates are important despite everything
Despite the temporary impact on battery life, Apple emphasizes the importance of software updates. New iOS versions like iOS 26 not only bring features but also important security improvements. They ensure that devices remain reliable, secure, and efficient in the long term. Temporary battery life limitations are part of the setup process and disappear once background tasks are completed.
