How to calibrate the iPhone battery

Calibrating an iPhone's battery is a process carried out to ensure that the device's operating system has an accurate reading of the battery's capacity. This is fundamental, because an iPhone's battery does not charge or discharge in a linear way, but rather its capacity varies with time and use. If the iPhone's operating system does not have an accurate reading of the battery capacity, it may show an incorrect charge percentage or make decisions about when to turn off the device to save energy. For all these reasons, calibrating the iPhone battery can help improve the accuracy of the battery capacity reading and its overall lifespan.

6 Steps to calibrate your iPhone's battery

Calibrating your iPhone's battery is a fairly easy process and requires only some time and patience; you just need to follow these steps:

1. Make sure your iPhone is updated to the latest version of iOS.
2. Use your iPhone normally until the battery runs out completely and it turns off on its own.
3. Let it rest about 6 to 8 hours without connecting it to power.
4. Connect your iPhone to a charger and charge the battery completely turned off for 6-8 hours.
5. Once the time has passed, we leave it a couple of hours without using it and disconnected from power.
6. Turn it on, pressing the power button and the Home button (in the case of iPhone X or later, we press volume up, volume down and turn it on). And that's it! You now have your iPhone's battery calibrated.

Why is it important to calibrate the iPhone battery?

Once you have completed these steps, the iPhone's battery should be calibrated and the operating system should have a more accurate reading of the battery capacity. Keep in mind that calibrating the iPhone battery is not a process that needs to be done frequently. Once every few months should be enough, as long as the iPhone is working properly.

Remember, too, that over time your iPhone's battery may lose its charging capacity and need more time to fully charge. Calibrating the battery can help improve the accuracy of the remaining charge indication and prolong the battery's lifespan.

However, you should know that calibrating your iPhone's battery is not a magic solution for all battery problems. If your iPhone has a damaged battery or is experiencing problems, you may need to take it to a technical service specialized in iPhone to have it checked.
