Dealing with iPhone battery issues? Here's the best way to calibrate your iPhone's battery

How Can You Calibrate Your iPhone’s Battery?

If you’re interested in maintaining your device, it’s a good idea to calibrate your iPhone’s battery. Another term for this is resetting an iPhone battery, and it’s a crucial element of iPhone maintenance. You shouldn’t need to calibrate your iPhone’s battery regularly, but it’s worth a shot if your device is older or you’ve had battery troubles that other fixes haven’t helped.

There are certain preparatory steps you’ll need to follow before you take the first step to calibrate your iPhone’s battery. They are all focused on disabling features and services so that as few tasks as possible consume power during the process.

This makes sure you get an accurate readout later in the process. You may re-enable all of these options after you’ve successfully reset the battery. It’s also worth checking Settings > Battery to make sure you haven’t mistakenly enabled low power mode.

Turn off Location Services

Before you calibrate your iPhone’s battery, follow these steps to turn off location services on your iPhone:

  • Launch the Settings app
  • Scroll down and select Privacy
  • Choose Location Services
  • Switch the Location Services toggle to the Off position.

Don’t forget to re-enable location services once you’re done calibrating, because you’ll need them if you ever need to locate a lost iPhone.

Turn off Background Refresh

You’ll also need to disable the background app refresh before you calibrate your iPhone’s battery, so follow the steps below:

  • Launch the Settings app
  • Select General
  • Choose Background App Refresh
  • Tap Background App Refresh once more
  • Choose Off

Reduce Your Screen’s Brightness

Here’s how to reduce the brightness of your iPhone’s screen:

  • Launch the Settings app
  • Scroll down and click Display & Brightness
  • Slide the Brightness slider to the left.

Disable Automatic Updates

Finally, to disable automatic updates before you calibrate your iPhone’s battery, perform the following three steps:

  • Access the Settings app
  • Scroll down and tap the App Store option
  • Disable the toggle next to App Updates

Steps to Calibrate an iPhone Battery

At this point, you’re now ready to calibrate your iPhone’s battery. Be aware that it will take some time, and you will need to wait for a number of complete charge and drain cycles.

Fortunately, no third-party tools or programs are required. Pay no mind to any app in the App Store that claims to help calibrate your iPhone’s battery. At best, such apps are unnecessary and at worst, fraudulent or maybe even malevolent. The iPhone battery calibration process is simple, just follow these steps outlined below.

Step 1: Drain the Battery

The initial step to calibrate your iPhone’s battery is to completely drain it. Do this through regular use; if there’s a series you’ve been planning to binge watch or a game you’ve been longing to play, now is the time to do so.

Step 2: Wait Three Hours

Perhaps you’ve noticed that your iPhone shuts down automatically even if it still has a bit of battery charge left. This procedure is intentional; it gives your phone a chance to store the current state of your apps so you don’t lose data.

So after you’ve drained your battery in the first step, it’s crucial to let the battery’s remaining life get exhausted. The only way to accomplish this is to wait. The longer you wait, the better, but you should wait at least three hours. Allowing your phone to sit overnight without charge is best if you can afford to do this.

Step 3: Charge Your Device

The next step to calibrate your iPhone’s battery is to recharge the device. Follow these tips to achieve peak performance:

  • Use a wall outlet rather than a computer to charge.
  • Use an official Apple charger whenever possible. At the absolute least, use a reliable Lightning cord rather than a cheap counterfeit.
  • Continue to charge for a few hours even if your phone’s battery is completely charged. To guarantee that the calibration works properly, you must squeeze in every last drop of power.

Step 4: Repeat the Process

You must now repeat the entire procedure a second time, completely draining the battery again, then fully recharging your phone. Make sure to follow the exact same steps you took before, making sure to let your phone charge for a couple of hours after it’s full.

Finally, when you’ve completed all the steps to calibrate your iPhone’s battery, you’ll need to re-enable the previously disabled services and functions. Reactivate Location Services, Background Refresh, and Automatic Updates, and also increase the screen brightness.

That’s all there is to it. Your iPhone’s battery has now been re-calibrated successfully.

To conclude, I’m sure the tips I’ve provided in this guide will help you calibrate your iPhone’s battery easily. However, you may want to consider purchasing a new battery for your iPhone if recalibration did not resolve your battery issues. Visit Apple’s Battery Service page to schedule an appointment.
