iPhone 17 battery drains quickly with normal use

📱 @Apple I recently upgraded to the #iPhone17 and the battery drain issue is really disappointing. Even with normal use, the phone loses charge way too fast. For such a premium device, this shouldn’t be happening.




Please address this with a fix/update soon. 🔋⚡

Why is this not common knowledge? Is there a way to test if that’s what’s happening or something else?

It is also detailed in the Apple Support Article here:

  • Immediately after completing an update, particularly a major release, you might notice a temporary impact on battery life and thermal performance. This is normal, as your device needs time to complete the setup process in the background, including indexing data and files for search, downloading new assets, and updating apps.

There is no message when the background processing is complete, but if you see a lot of Battery usage showing Home & Lock Screen, that is an indicator that it is still indexing. Usually it should be done in about 3 days, give it a week to be sure. The alternative is to include the indexing/setup in the update, which would dramatically increase the update time where your device would not be usable.
