In this article, I will show you how to calibrate your iPhone’s battery for a more accurate percentage. Have you ever noticed how your iPhones battery percentage becomes unreliable or jumpy especially during the last few hours of usage before it runs dry? This is because your iPhone isn’t calibrated.

We all have problems with battery life and it’s not necessarily a problem for most, but there are a lot of people that get their percentages to around 20% and then the phone dies.

If your iPhone tends to switch itself off, it might be due to inaccurate estimations. Calibrating the iPhone battery is accomplished by fully discharging the iPhone through regular use but without using the phone itself and then charging it back to 100%. I will show you how to do this properly.

What does Calibrating a Battery Mean?

When your iPhone’s battery shuts down suddenly, this doesn’t mean that the battery is dead. When this happens, it means that the battery has merely dropped in voltage to a level that cannot keep the iPhone running stable.

This results in the software shutting down the phone. In simple terms, your Battery is not drained all the way, it is just at the lower limit of its usability. So, since you are not running the battery dead, draining the battery till it shuts off once a month to calibrate it, should not hurt the battery.

Battery calibration only makes your icon or percentage more accurate. It doesn’t physically do anything to your actual battery. Every time the battery is fully drained, a small percentage of remaining life is removed, which is why calibrating your iPhone’s battery more than once a month is not recommended.

How to Recalibrate your iPhone’s Battery

So, the first thing you want to do is:

  • Go in the Settings app from your home screen
  • Anything that you’ve set to full that affects your battery, turn it all the way down or Off
  • This can include the brightness, WI-FI, Bluetooth, mobile data, and volume

Just make sure that everything is as low as you can get it to. You don’t want to leave any settings on that affect your battery majorly.

The next thing you want to do is to:

  • Turn your music playlist On (iTunes or Spotify)
  • This can be any music app that plays music while the screen is off
  • Press your first song and hit shuffle
  • Leave your iPhone and wait for it to die completely
  • Once it dies, charge it to 100% without touching it completely

Once it hits a hundred percent, that should be it for the recalibration. If your iPhone still dies on a high percentage, this will indicate how healthy your battery is.

The lower the percentage your iPhone’s battery dies on after you’ve calibrated it, the better the health of your battery.

Bottom Line

Calibrating your battery will give you a better battery life and it will make your iPhone or iPad last longer rather than dying suddenly. If it doesn’t work the first time, do it again. If you see no success the second time, do it one more time.

Make sure that when you do this, everything is off. You want to find something that will use up your battery extensively and kill it without you being on it excessively which is why I suggested playing music.

Don’t touch your phone while you’re charging it because the calibration will not work at all. This is what causes calibration issues.

Whenever you have your phone on a charger and you decide to use it and play a game or use anything that can kill the battery while it’s charging, this will mess up the timing and the calibration of the battery, therefore, causing worse battery life than what you have now.
