Written by admin

if your iPhone 12 miniiPhone 12iPhone 12 Proor iPhone 12 Pro Maxs the battery life starts to drain faster than it should, there are some steps to take before contacting apple customer support.

We haven’t seen widespread complaints about battery life, but some iPhone 12 users say their device’s battery is draining faster than it should.

Battery life issues are common, especially after Apple released new iOS 15 software, and we know that 5G drains batteries faster than LTE, so these complaints aren’t surprising.

If you find that the battery is draining severely, there are some steps you can take to fix the problem. In this guide, we will walk you through some solutions that can help you fix iPhone 12 bad battery life.

These are solutions that have worked for us over the years that can help you fix your battery issues in minutes and help you avoid a call to Apple customer service or a visit to the Apple Store.

Restart your phone

If your battery is draining faster than you think it should, we always recommend restarting your phone before doing anything else.

Turn off your iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max, wait a minute, and then turn it back on. If it still drains quickly, continue with these other steps.

Update your iPhone

Apple periodically releases iOS 15 software updates for the iPhone. Point updates (xxx) usually focus on fixing bugs, while milestone upgrades (xx) usually offer a mix of features and fixes.

The company may not list battery life fixes in the change log of an iOS 15 update, but new firmware always has the potential to help alleviate battery problems.

Refer to that guide to learn more about the latest version of iOS 15.

Turn off 5G

The iPhone 12 series supports 5G connectivity. While it is fast, it can drain your battery much faster than LTE. If you don’t need to use 5G all the time, go to the settings of your iPhone 12.

iOS has a few 5G settings that you want to commit to your memory bank. To find it, go to Settings, then Cellular, then Cellular Data Options, then Voice & Data.

If you are in the right place, you will see three options:

5G On means your iPhone uses 5G when it’s available, even if it could reduce your device’s battery life.

The 5G Auto option only uses 5G if your phone’s battery doesn’t drain significantly. 5G Auto is the default and option that most people should select.

Check your apps

Apps can sometimes negatively impact your phone’s battery life and you’ll want to check them out if you notice the battery draining abnormally.

Checking the app performance is extremely easy on iPhone 12 series. Here’s how to do it:

  • Go to your Settings app.
  • Select Battery.
  • Check your battery usage.

This battery usage tool shows you which apps are draining your iPhone 12’s battery and when they do.

If you use an app a lot, it will obviously use more battery than apps you never use. So if you see an app that you rarely use and consume a lot of power, you’ll want to explore it further.

If you see an app that is eating up a ton of battery life, try uninstalling the app from your device and see if everything goes well.

If the app is essential for your daily use, we recommend that you download the latest update from the developer. If that doesn’t help and you really need the app to get through your day, you may need to downgrade back to an earlier version of iOS 15.

Reset all settings

If you’re sure it’s not a problem with one or more of your apps, try resetting your iPhone 12’s settings.

Before doing this, keep in mind that your device will forget known Wi-Fi networks, so be sure to write down or save your passwords somewhere before doing this. Here’s how to do it on iOS 14:

  • Go to Settings.
  • Go to General.
  • Scroll and tap Reset.
  • Tap Reset All Settings and enter your passcode if it is enabled.

If you’re using iOS 15, here’s how to reset all your iPhone settings:

  • Go to Settings.
  • Go to General.
  • Scroll and tap Transfer or Reset iPhone.
  • Tap Reset.
  • Tap Reset all settings.

Once the process is complete, you will need to reconnect your iPhone to your Wi-Fi network(s) and Bluetooth devices.

Use power saving mode

Power saving mode helps you conserve battery life by turning off services (Hey Siri, automatic downloads, and email fetch) that can drain your battery.

You can turn the power saving mode on and off at any time and the operating system will also prompt you to turn it on when your iPhone reaches 20% battery.

If you haven’t already done so, add Low Power Mode to your Control Center. Control Center is the menu that appears when you swipe up from the bottom or, if you’re using a newer iPhone model, from the top right corner of the screen. Here’s how to do that:

  • Go to Settings.
  • Tap Control Center.
  • Tap Customize Controls.
  • Tap the green plus sign next to Energy Saving Mode.

The next time you open the Control Center on your phone, you will see a battery icon. Tap it to enable or disable Low Power mode on your device.

You can also enable Low Power Mode from your Settings. Here’s how to do that:

  • Go to Settings.
  • Tap Battery.
  • Tap Energy Saving Mode.
  • Turn it on.

Stop background refresh

Background App Refresh refreshes apps in the background to show you the latest data when you open them. It’s a useful feature, but it can also come at the cost of battery life. If you don’t need it, try turning it off. Here’s how to do that:

  • Go to Settings.
  • Tap General.
  • Tap Refresh app background.
  • Disable it for any applications you are not using.

You can also disable it altogether if you don’t want to go through your apps one by one.

Downgrade your iPhone 12 software

If you can’t find a solution to your problem and/or don’t want to wait for the next iOS 15 update from Apple, you can try downgrading your iPhone 12 software.
