How To Fix iOS 16.1.1 Battery Drain Problems

Battery issues have been reported ever since the release of iOS 16! While some consider that iOS 16.1.1 is the worst release when it comes to battery management, there are other that praise their iPhone’s battery performance after the update.

On thing is certain, Apple definitely has to optimize the new OS. Until then ,you can use the following tips to fix extreme battery drain on iPhone:

1. Restart iPhone

A reboot could flush any lingering processes stuck after the update. Before, you apply any other troubleshooting steps you should preform a force restart.

How to: Click & release Volume Up, followed by Volume Down and press & hold the Side button until the Apple logo is displayed on the screen. Be patient until your device reboots, provide passcode when asked and resume usage.

2. Tweak Siri Settings

Some users have reported huge Siri battery usage. If you’re experiencing the same in Settings -> Battery -> Battery usage by app do the following:

• Go for Settings -> Siri & Search.
• Turn Off Listen for ‘Hey Siri’.
• You can also try disabling Suggestions from Apple.

Fact: Siri might be indexing heavily after update. It might scan your photos for duplicates and more. If the situation persists 48 hours after installing iOS 16.1.1, you should try the above fixes.

3. Ditch Lock Screen Widgets

We’ve noticed that Lock Screen widgets can become important battery hogs.

One of the problematic widgets is the Weather widget. We’ve already covered that a Weather bug in iOS 16 is causing the app to update forecast with a significant delay.

We recommend you to remove all Lock Screen widgets for the time being and observe if screen time increases.

How to: Wake iPhone and touch & hold screen until the Lock Screen edit menu shows up. Tap Customize and remove widgets using the ‘–‘ symbol in the top-left corner of the item.

4. Switch To 4G Only

5G connectivity is burning extra battery especially when the signal strength is weak. Yesterday, I managed to lose 50% battery charge within 3 hours while having dinner in a location with poor cellular coverage. I barely used the phone.

Try to switch 5G completely off and let us know if you notice a difference:

• Open Settings and go for Cellular -> Mobile Data Options.
• Tap on Voice & Data.
• Select 4G instead of 5G Auto or 5G On.

Extra tip: If you spend more time in a location with poor carrier signal you can turn on Airplane Mode and enable Wifi and Bluetooth from Control Center. You shouldn’t miss calls as long as Wi-Fi calling is enabled!

5. Downgrade to iOS 16.1 / 15

If you can’t fix iOS 16.1.1 battery issues, your last option is to revert to a previous version!

iOS 16.1 is still signed, which means that you can downgrade without losing data if you consider that your iPhone’s battery performance was better with the previous version.

If that’s not the case, you can also downgrade to iOS 15.6 and stay on it, or update to iOS 15.7.1, over-the-air and remain on iOS 15 until Apple releases iOS 16.2 or a more battery friendly version!
