iPhone dying before battery runs out

So, you’re using your iPhone and you seeing that your battery is going down quite quickly.

Before you have a chance to even charge your iPhone, it turns off because you thought you had plenty of battery left.

This can be a frustrating situation because you now have to wait for your iPhone to restart again.

In this article, I’m going to show you what to do when your iPhone turns off before the battery runs out.

This could be 50%, 30 %, 20%, or any low battery amount and this problem normally affects older iPhone models.

I’m going only going to show you reliable ways to fix this problem so that you don’t have to keep trying useless solutions.

Why Does my iPhone Die with Battery Left?

The reason your iPhone or even your iPad tends to switch off early is because your iPhone is incorrectly estimating the battery power left.

When your iPhone is showing you 20% before it turns off, for example, it’s actually on 1%.

That’s why when you charge your iPhone after it turns off, it goes back to the same percentage it was on before it turns off.

This is because your iPhone just thinks this is 1%.

This also doesn’t necessarily mean that there’s a problem with your battery.

Down below are a few ways to fix this problem and they’re not going to be very simple.

You can’t just restart your iPhone for example.

Let’s get started…

Calibrate iPhone Battery

The first way you can fix this problem is to calibrate your iPhone back to the real battery percentage.

This is a long process that the second method but it’s not as technical.

If you’re a patient person and you don’t like technical things, you should calibrate your battery by letting it drain.

First, you want to:

  • Go in the Settings app
  • 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

You’ll need to make sure that you reduce anything that can take away your battery.

This is going to be important for the next step.

To calibrate your iPhone battery by draining it:

Charge iPhone to 100% to stop it dying early

  1. Turn On a long music playlist (iTunes or Spotify)
  2. This can also be any music app that plays music while the screen is off
  3. Play the playlist and lock your iPhone
  4. Do not touch your iPhone and wait for it to die completely
  5. Once it dies, charge it to 100% without touching it completely
  6. Your iPhone should now drain to 1% before it turns off

After your iPhone has reached 100% battery, it should be calibrated, and you should no longer suffer from this problem.

This process does take some time which is why you need to be patient.

If you’re still experiencing this problem, try the next step.

Restore your iPhone

The next reliable way to fix this problem would be to restore your iPhone.

Restoring is a troubleshooting process Apple made in order to help you fix your device if it was experiencing problems.

Restoring your device is going to calibrate your iPhone battery.

If you’ve done this before and you can install iTunes on your PC, you can use this method over the previous method.

Restoring your device is going to wipe the data from it so you need to have a backup.

If you don’t have a backup, I’ll show you in the steps below.

To calibrate your iPhone by restoring:

  1. Go to iTunes on your PC
  2. Click on the Device icon on the left
  3. Go to the Summary tab
  4. Under Back Up and Restore, Click on Back Up Now
  5. After Backing up, Click on Restore iPhone at the top
  6. Wait for your iPhone to Restore and Turn on

After you’ve done this, you need to restore your iPhone during the setup when you see the Apps & Data section.

If you have no idea what I’m talking about, check out how to restore your iPhone from a backup.

You should now notice that your battery has fully calibrated with the iPhone.

Your iPhone should only turn off when it’s at 1%.

When you restore your backup, it’s going to take a long time for everything to go back onto the device.

If you don’t see your camera roll, don’t worry, it takes up to 24h for it to come back.
