If your iPhone battery seems to drain faster after installing iOS 26.1, there’s no need to worry. Apple has officially confirmed that this drop in battery life is temporary and part of the normal post-update process.
Apple released iOS 26.1 earlier this week, introducing new features and performance upgrades, including additional settings for the Liquid Glass function. Soon after the rollout, several users reported that their iPhone battery was depleting more quickly than usual.
According to a statement from Apple’s support page, such behavior is common after major software updates. The company explained that the iPhone performs multiple background tasks after installation, which can temporarily affect both battery and thermal performance.
Apple noted, “This is normal, as your device completes setup tasks in the background, such as indexing files, updating apps, and downloading new system assets.” During this process, the iPhone battery is under heavier load, which leads to increased power usage. However, once these background activities are complete, the battery life should return to normal.
The company also mentioned that user habits can influence how much battery is consumed. Exploring new features, using the phone for longer periods, or testing out updated apps can all contribute to faster battery drain in the first few days after the update.
Apple reassured users that this situation is temporary and has been observed after previous iOS updates as well. Once the device finishes all background optimizations and recalibrations, performance and battery efficiency will stabilize automatically.

In summary, a faster-draining iPhone battery after installing iOS 26.1 is nothing to be alarmed about. Apple advises users to be patient and allow a few days for the system to adjust. Once the optimization process completes, normal battery life should resume.
