How To Fix Bad iOS 15 Battery Life

If you start noticing excessive battery consumption on your iPhone after installing the latest version of iOS 15, there are some steps you should take before downgrading your device or contacting customer service.

While moving away from Apple’s latest iOS 15 release, iPhone users are reporting various issues with iOS 15. One of the issues on the list is abnormal battery drain, a common issue that occurs after every iOS release.

Some of these battery problems may be hardware related, but others are likely related to Apple’s latest software update. In most cases, it’s probably an app causing the problem.

If you’re experiencing excessive battery life after upgrading to iOS 15, you may be considering reverting to the older iOS software. This is definitely an option, but you should try to fix the problem so that you can continue using the latest firmware.

Fixing iOS 15 battery life issues can be tricky, but we have some solutions that have worked for us and many other iPhone users in the past. Hopefully they will be of use to you.

Restart your phone

If you start noticing abnormal drainage after installing iOS 15, we recommend restarting your phone before doing anything else.

Turn off your iPhone, wait a minute, and then turn it back on. A quick reboot can have a tremendous impact on the performance of your device so this is the first thing to try.

Update Your iPhone

Apple will periodically release new iOS 15 software. Point updates (xxx) typically focus on fixing bugs, while landmark upgrades (xx) often offer a mix of features and fixes.

The company may not reveal battery life fixes in an iOS 15 update’s changelog, but new software always has the potential to help cure your device’s woes.

If a new software update is available, review feedback on its performance and then decide if it’s worth installing.

Control Your Apps

Apps, especially third-party apps, tend to take action after Apple releases new iOS software. So there’s a good chance that one or more of your apps is the source of your battery life issues.

Checking app performance is pretty simple on iOS 15 and it may only take you a few moments to find the app or apps that are causing the issue. Here’s what you need to do:

If you use an app on your phone a lot, it will definitely consume more battery than an app you never use. So if you see anything out of the ordinary, like an app you rarely use to drain the battery, you’ll want to investigate further.

If you find that one or more of your apps is consuming an abnormal amount of battery, try deleting the app from your device and see if that improves your iPhone’s performance.

If the app is important, we recommend downloading the latest updates. If that doesn’t work and you really need the app to spend your day, you may need to revert to an older iOS version if the option is available.

reset all settings

If you determine that your apps are not the source of your battery problems, you should now try resetting your iPhone’s settings.

Before doing this, be aware that it will cause your iPhone to forget known Wi-Fi networks (and Bluetooth connections); so be sure to type in your passwords if needed before touching reset.

Here’s how to reset all your iPhone’s settings:

You will need to reconnect to your Wi-Fi and Bluetooth devices once the process is complete.

downgrade

If you can’t find a solution to your problem and/or don’t want to wait for Apple’s next iOS 15 update, you can try reverting to an older iOS version.

Your downgrade options will change over time and downgrade may not be available as Apple stops signing in to older iOS software.
