Sometimes, new software updates can cause compatibility issues with your apps or hardware, which can lead to increased battery usage. If this is the case, you may need to wait for an update from the app developer or contact Apple Support for assistance.

In addition to software updates, new app installations can also cause battery drain. It’s important to make sure that the apps you install are optimized for the latest version of iOS and that they have good reviews from other users.
