Poor battery life is a perennial complaint of smartphone users.Whether you're an iPhone or Android user, if you're using your phone a lot during the day, it's nice to have a battery that lasts until sunset.

However, did you know that something as simple as calibrating your iPhone battery can help you?Let's take a closer look at how to calibrate an iPhone battery and why calibration is important.


Why you should calibrate your iPhone battery

Calibrating your iPhone battery (also known as resetting the iPhone battery) is a surprisingly important part of iPhone maintenance.Unfortunately, many people don't realize its benefits, and even fewer take the time to perform the necessary steps.

Without a properly calibrated battery, you're likely to experience inaccurate and erratic battery percentage readings, faster battery drain, and shorter overall battery life.If your iPhone unexpectedly shuts down at a single-digit battery life percentage, it's almost certainly caused by improper calibration.

Many factors can cause incorrect battery calibration.Software updates, background app refreshes, new features, and even normal day-to-day use can cause differences.Even if you don't notice an incorrect calibration, performing the steps below will ensure that all the ions in the battery are flowing, improving the battery's peak performance.

While you don't need regular calibration, it's worth a shot if you have an older iPhone or if you have battery issues that other steps didn't fix.

Preparing to Calibrate Your iPhone Battery

Before starting the calibration process, there are several steps you should take to prepare.They all revolve around disabling features and services, so as few tasks as possible consume energy.

This will help in getting accurate readings later in the process.After you reset the battery, you can re-enable all of these options.It's also worth making sure you haven't accidentally enabled Low Power Mode by going to Settings > Battery.

To disable location services on your iPhone, follow these steps:

1. Open the Settings application.

2. Scroll down and tap Privacy.

3. Select Location Services.

Remember, you can use location services to track a lost iPhone, so make sure you don't forget to re-enable this feature after you're done calibrating.

How to Calibrate iPhone Battery

Now you're ready to calibrate your iPhone's battery.Note that this requires considerable patience; you'll need to wait a few full charge/discharge cycles to complete.

Fortunately, you don't need any third-party tools or apps.Anything you see on the app store that claims to reset your iPhone's battery is, at best, unnecessary, and at worst a hoax.

Step 1: Drain the battery

The first step is to completely drain your iPhone battery.You can do this in normal use.If you want to speed up the process, you can play a long video on YouTube with the volume turned up to max.

Step 2: Wait Three Hours

You may have noticed that your iPhone automatically shuts down even when there is only a small amount of battery left.This process is by design; it gives the device a chance to save the current state of your app so you don't lose data.

It's important to let the last embers of battery life fade away.The only way to do this is to wait.The longer the better, but you should wait at least three hours.If you have time, it is best to leave it overnight.

Step 3: Charge Your Device

Now is the time to recharge the battery.To ensure optimal performance, make sure you follow these tips:

1. Use a wall outlet instead of a computer to charge.

2. Ideally, use an official Apple charger.At the very least, make sure you're using a trusted Lightning cable, not a cheap knockoff.

3. Even if your phone shows that the battery is XNUMX% full, keep charging it for a few hours.You need to make sure every drop of energy is squeezed in to make sure the calibration is working properly.

Step 4: Drain Your Device

Now you need to repeat the whole process a second time.This is the same exercise as before: completely draining your device's power.You can use it as usual, or loop the video to speed it up.

Step 5: Wait Another Three Hours

It's getting more and more repetitive now, but keep at it.Once again, you need to make sure to drain your iPhone's last bit of battery power.As before, the longer you can leave it on, the better.

Step 6: Charge Your Device

To complete the process, you need to charge your device.Following the same guidelines as before, make sure you keep your phone charging for a few hours, even after it's fully charged.

Finally, you need to re-enable the services and features you disabled earlier.Turn location services, background refresh, and automatic updates back on, and turn up the screen brightness.

That's it.Now your iPhone battery has been recalibrated.

Other battery-saving iPhone tricks

If recalibration doesn't fix your iPhone battery issues, it might be time to spend some money on a new battery.You can replace the battery yourself if you feel confident, but doing so will void your phone's warranty.

Alternatively, you can go to Apple's battery service page to make an appointment.A new battery and required labor isn't as expensive as you might think.
