Many iPhone users reported a reduction in battery life after updating their phone, especially after significant updates like iOS 27. Complaints multiplied among Apple device owners.
Apple officially responded to these concerns, classifying this battery reduction as a "normal" and "temporary" behavior. The company did not specify exactly how long this situation may last.
This is not the first time the problem has appeared after major software updates. Normally, the operating system takes some time to optimize background processes and reindex applications after an update.
Apple recommends that users wait a few days for the device to adapt to the new version of the operating system before drawing conclusions about the actual battery performance.
