iOS 14.2 battery drain bug

Is your iPhone battery draining faster since you updated to iOS 14.2? More, is your device taking longer than usual to charge? Apparently, this is a common problem especially for owners of older iPhone models. A bunch of reports regarding the iOS 14.2 battery drain issue have been mailed to us over the weekend and we could find a series of similar cases on Reddit and Apple’s Developers Forums.

iOS 14.2 Battery Drain Bug

The main symptom of this problem is represented by an accelerated battery drain that can’t be justified by the user’s iPhone usage. The quick battery loss comes in large drops of a short period of time, with up to 30% of a drop in less than 1 hour, of medium to light usage.

Users also report that severe battery draining occurs even overnight, with the device losing up to 49% in battery load over the span of 8 hours of idle time.

More, some report that the drop is sudden and usually happens after the battery percentage is stuck at a high level for a longer period of time. However, even this can’t explain a drop of 80 percentage points during a 30-minute voice call.

Fact: The issue is frequent in older iPhone models like the iPhone 6S, 7, 8 and even the iPhone X. Important: All these devices do have a Maximum Capacity reading of over 80% and the Battery Health is labeled as being at ‘Peak Performance Capability’!

How To Fix iOS 14.2 Battery Drain Issue

Unfortunately, there is not much that you can do at the moment to improve this issue. Some of the troubleshooting methods that we can suggest are:

  • 1. Reboot iPhone

    Some users have reported that restarting their devices caused a sudden gain in battery percentage, but this can only confirm that the issue is indeed caused by a software glitch and not a malfunctioning iPhone battery.

  • 2. Offload Apps

    Not all iPhones are affected by the iOS 14 battery drain bug, which means that the problem might be caused by a certain app or function that’s run by your device. Try to pinpoint the triggering factor. If you have any apps that you downloaded recently you should temporarily delete them. Test to see if severe battery draining continues. If the problem is solved, reinstall one app at the time and test if the battery drain issue reoccurs.
    How To: Settings -> General -> iPhone Storage -> tap on the app in question and offload it.

  • 3. Remove Widgets

    In some cases third-party widgets could be poorly coded and come with battery straining bugs. Try to delete all your Home Screen widgets and see if the the problem is fixed. If you get a positive result, start reading widgets one at a time to pinpoint the glance that’s causing the iOS 14.2 battery drain.
    Tip: The problem can also hide in the widgets available in the Today’s view, especially on iPads (mini, 2018 iPad Pro) running iPadOS 14.2.

  • 4. Disable Exposure Notifications

    Your local COVID-19 contact tracing app could also be the cause of the iOS 14.2 battery draining issue. You can temporarily disable Exposure Notifications and see if it makes any difference.

  • 5. Update To iOS 14.3

    Another option is to install the upcoming iOS 14.3 update on your device. iOS 14.3 is currently beta tested, but you can download it for free if you sign up for Apple’s Beta Software Program as detailed here.
    We don’t have a confirmation that the battery drain issue is fixed in iOS 14.3 Beta 3. Use the comments section to share your feedback if you try it out.

Fact: Using your iPhone in a cold environment could lead to increased battery draining, as Li-Ion batteries drop in performance when the temperature comes close to freezing levels. However, this isn’t the main cause of the iOS 14.2 battery drain issue!

Conclusion: While there are plenty complaints about severe iOS 14.2 battery drains, there are also iPhone users that claim that iOS 14.2 has improved the battery life on their devices when compared to iOS 14.1 and iOS 14.0.

If you recently installed iOS 14.2 while switching from iOS 13.x or during the process of restoring your iPhone, please give your iPhone a couple of days time to re-index your iCloud data and other settings. This procedure will cause quick battery drain and is normal. If the battery drain problem continues after this it means that you do need to attempt to debug it!
