Try This iOS 16.2 Battery Drain Fix

We’ve recently covered that a series of readers are hit by Apple Watch battery draining very fast after watchOS 9.2 update.

Some, even reported that the problem started after updating the paired iPhone to 16.2 and the Watch still on watchOS 9.1.

Many of them have managed to fix this problem by rebooting both devices and / or unpairing and re-pairing Apple Watch. That’s why we recommend the following:

1. Reboot iPhone

A fresh start could kill any lingering processes that might drain battery after the iOS 16.2 update. Use the force restart combo for quick results.

Tip: If you’re using an Apple Watch reboot it too in the same time with your iPhone!

2. Re-Pair Apple Watch

Also, make sure that a glitch involving the communication with a paired Apple Watch is causing the iOS 16.2 battery problems.

You can eliminate this potential cause by unpairing and re-pairing the watchOS device from the Watch app on your iPhone:

  • 1. Tap on All Watches in the top-left corner.
  • 2. Go for the ‘i’ icon, next to the name of your Apple Watch.
  • 3. Select Unpair Apple Watch. (A backup of your device will be automatically created and saved on your iPhone)
  • 4. Re-pair wrist-worn gadget and use it normally.

3. Remove Lock Screen Widgets

If iOS 16.2 battery issues persist, I recommend you to remove all Lock Screen widgets!

The Lock Screen has been completely revamped in iOS 16 and it might still not be fine tuned enough:
