How to Fix Battery Drain Issues After iOS 15 Update

If you have an Apple device, you probably updated to iOS 15 and rushed to use the widgets, designs, and automation features this new update offers. After the frenzy of design, you may have noticed that your iPhone started acting a bit weird.

Its battery was running out faster than usual, and you were finding yourself having more frequent charging sessions. Don’t worry. You are not alone.

Apple introduced iOS 15 in June 2021, which was then released to the public on September 20th. iOS 15 introduced new features for FaceTime calls, tools to reduce distractions, a new notifications experience, and much more. 

But these new updates came with a cost since several issues arose with battery life and the temperature climbs in heavy usage.

So in this article, we will give you the fixes. Let’s get started!

1. Turn off Background App Refresh

Background app refresh needs a lot of power to run, so it needs smart management no matter the device you are using.

  1. First, open your Settings app
  2. Then, tap General > Background App Refresh > Background App Refresh. Now, you can either choose to completely turn it off, which I wouldn’t recommend since you need apps like your email or iCloud to background refresh. To avoid that, you can turn off background refresh for specific apps.

You can also force quit apps when you don’t use them. 

  1. On Face ID devices, swipe up from the Home bar at the bottom, and hold along the middle of the screen to open the app switcher.
  2. On Touch ID devices, double press the Home button to open up the App Switcher. Then, swipe up on the app card to force stop an app.
