Gofrixty [19 September 2025] – Apple has now officially warned users that the new iOS 26 update may have a temporary impact on iPhone battery life. Millions of people have already began installing the update, and some report that their phones are draining more quickly than usual. Apple has confirmed that this is to be expected and explained why.
After a big iOS update, iPhones perform all sorts of background tasks. This encompasses things like re-indexing files, updating apps, syncing photos and downloading system assets. All of that processing adds extra load to the system, which naturally drains the battery more rapidly. Apple clarified that this is not an iOS 26 glitch but a transient effect that will gradually improve over the first few days as iPhone boots its background activity.
The company also noted that some of the new features in iOS 26 — like enhanced widgets, smarter A.I. tools and more background processes — might require additional power initially. So for example, performance might also feel a tiny bit slower to some users immediately after the update. But Apple promises that iPhone battery life and performance will normalize once the update has fully been settled in.
