How To Calibrate iPhone’s Battery

Iphone Battery Settings

The iPhone is notorious for having excellent battery life. However, that might not apply to every device. If you’ve been using your phone for a while, the chances are that your battery life is draining due to you not calibrating your iPhone’s battery.

Quick Answer

Here are all the methods you can use to calibrate your iPhone’s battery.

• Apple Automatic Battery Calibration.
• Manual Battery Calibration.

In this article, we’ll go over all the different ways you can calibrate your iPhone’s battery and why you need to do so in the first place.

What Is Battery Calibration, and Why Do You Need It? 

Battery calibration refers to the act of ensuring your battery is charged and drained at its maximum capacity. Generally, almost every device that has a lithium-ion battery requires calibration after 200-300 charge cycles.

In most cases, using your iPhone and charging it frequently will lead to slight inconsistencies between the actual battery life of your phone and what it’s being shown as. So, you might end up with your iPhone randomly dying out when it is at 10-20% or displaying signs of inferior battery life.

To circumvent that, battery calibration is necessary. With iOS 14.5, models newer than the iPhone XS do not require manual battery calibration, as Apple does it for you automatically.

However, you may still need to calibrate your battery manually once in a while, as we haven’t been able to spot a frequent pattern for automatic battery calibrations to make a difference.

When Do You Need Battery Calibration?

If you are experiencing any of the following issues, you need a battery calibration.

  • Frequent Battery Drains: If you’ve been using your iPhone normally but suddenly see its percentage dropping much faster than usual, calibration might be in order.
  • Shutdowns: A faulty battery might be to blame if your iPhone shuts down randomly and doesn’t seem to boot back up without a charge.
  • Performance Degradation: Often, Apple hinders your phone’s performance (underclocking) from ensuring you get decent battery life. If your battery is not calibrated, this may often happen for no particular reason. 

Method #1: Apple’s Automatic Battery Calibration

The advent of iOS 14.5 brought about the ability to calibrate your battery for the following phones.

  • iPhone 11.
  • iPhone 11 Pro.
  • iPhone 11 Pro Max.

You can now calibrate your battery in these phones if Apple allows you to. The reason why this option is limited to a few phones is due to Apple’s fault. With multiple updates, the iPhone 11’s Internal Battery Reporting generated false battery health reports.

To circumvent that, some phones had their batteries manually automatically recalibrated. You can check if your iPhone 11 series fits the bill by heading to Settings > “Battery” > “Battery Health“.

If you see the message above, your battery is automatically calibrated, and you should check back in a few weeks to see whether your battery performs better!

Note

Automatic Battery Calibration can also occur with newer models of iPhones. However, the trigger at which it happens is controlled by Apple, and there is no way for you to invoke the option manually. 

Method #2: Manual Battery Calibration

By draining your battery repeatedly, waiting for a while, and repeating the process, you can successfully calibrate your iPhone’s battery and get some of your performance back.

We’ve gone and tried these steps and have been able to solve issues like battery drain and our battery inexplicably dying out at about 10-15%. If you are suffering from these issues, the chances are that your battery isn’t charging correctly due to it not being calibrated.

Here’s what you can do to fix just that.

  1. Keep using your iPhone until it dies. If you have a battery that isn’t correctly calibrated, it’ll die much earlier than before it hits 1%.
  2. Do not use your iPhone for about 2-3 hours. During this process, keep it at room temperature and don’t let it be subjected to extreme climate.
  3. Charge your phone to 100%. Take a note of how long it takes to get to that level.
  4. Keep repeating the process until your iPhone dies at 1% and does not tap out earlier. Once that happens, you’d have successfully calibrated your battery.
Note

Contrary to popular belief, your battery health is not changed when manually calibrating. While you will sense an improvement in battery life – your battery health will remain the same

Conclusion

Calibrating your iPhone’s battery is essential if you have been using it for a year or so. Besides that, Apple has been improving its battery reporting to ensure your phone calibrates automatically in the first place.
