iPhone battery draining fast right after an update
Your iPhone is reindexing Spotlight and rebuilding its system after the update. This drains battery for 24-48 hours while it works in the background. Wait a day or two. The battery will return to normal once the reindexing finishes.
When you update iOS, your iPhone rebuilds its system index in the background. This process, called Spotlight reindexing, uses a lot of power and makes the battery drain faster than normal. It finishes within 24-48 hours and battery returns to normal. You can speed it up by letting the phone charge overnight, or turn off background activity while waiting.
- ✓Keep your charger nearby for the next 24-48 hours
- ✓Avoid using the phone intensively while it's reindexing
- ✓Plan to charge it overnight to help the process finish faster

Skip, I just want a technicianCommon mistakes to avoid
- Assuming the battery is broken after an update. Reindexing always causes temporary drain.
- Restarting the phone repeatedly thinking it will help. This just makes reindexing take longer.
- Not updating apps to the latest versions that support the new iOS.
Signs you need professional help
- Battery is still draining fast after 48 hours even though no specific app shows excessive usage, the phone is very warm 48 hours after the update, or battery drain gets worse instead of better after 24 hours.
