If you want to know how to Calibrate an iPhone’s Battery, we have the original, complete guide based on information from Battery University and Apple. It’s too bad that you can’t reset the iPhone’s battery health without replacing the battery. If you want to know how to get an iPhone’s battery health back to 100%, calibration simply won’t help you. To fix the health of an iPhone battery, you have to replace it.
Calibration (or “recalibration”) of the battery on your iPhone will make the battery meter more accurate. An adjustment will fix your iPhone if it turns off before the battery level indicator shows 1%. If you want to know how to Calibrate an iPhone’s Battery, the only thing you can do is replace it. The health of your iPhone battery will not get better by recalibration.
What is battery calibration?
Every operating system, including Android and iOS, checks the battery level all the time. So, the screen can show how much power is left in the battery, whether it is full or empty. There were, however, problems that came after it. The information that is given isn’t always correct. So, the phone turns off all of a sudden for no reason, even though the battery level hasn’t dropped to 0%. This difference in data is usually due to the device being old.
This is because over time, all types of batteries lose some of their quality. For the most part, used batteries can’t hold as much power as brand-new ones. The issue is that the device’s operating system can’t explain why the quality is getting worse. So, the battery needs to be calibrated. Calibration of the battery is what makes sure that the operating system gets correct information. In this way, you can trust the data that shows up on the screen. You must now have a better idea of how important this method is based on what it does, right?

How to Calibrate an iPhone’s Battery
Charge Your iPhone
- Plug your phone into the wall instead of your computer to charge it.
- If possible, use an official Apple charger. If you have an iPhone 15 or later, at the very least, make sure you use a reliable Lightning cable or a good USB-C cable and not a cheap copy.
- Even if your phone says the battery is fully charged, keep charging it for another two hours. To make sure the calibration works right, you need to make sure you squeeze in every bit of power.

The next step is to drain your iPhone’s battery all the way down. During normal use, you can do that. You can speed things up by playing a long YouTube video with the volume all the way up.
Why is it important to calibrate your iPhone’s battery?
- Accurate Battery Percentage: Calibrating ensures that the battery percentage displayed on your iPhone is accurate. Over time, the battery’s capacity can change, and calibration helps your device accurately reflect the remaining battery life.
- Optimized Performance: Calibrating the battery can help your iPhone maintain optimal performance. When the battery percentage is correctly calibrated, the device can better manage power consumption and avoid unexpected shutdowns.
- Battery Lifespan: Proper calibration can extend the overall lifespan of your iPhone’s battery. It helps prevent overcharging and deep discharging, which can lead to battery degradation over time.
- Predictable Battery Life: Calibrated batteries provide a more predictable battery life. You’ll have a better idea of how long your device can run on a full charge, which is crucial for planning your usage, especially when you’re away from a charger.
- Software Functionality: Some software features, such as battery health monitoring and optimization, rely on accurate battery calibration. A well-calibrated battery allows these features to work effectively.
Questions and Answers
Click on “Battery Health” above your battery graph next. There is an important battery message at the top of this page. It lets you know that your iPhone’s maximum battery capacity and top performance are being re-calibrated. Tap “Learn Mode” to go to a help page where you can read more about it.
A lot of people, including Apple, say that you should try to keep your iPhone’s battery between 30% and 80% charged. Putting the battery back to 100% isn’t recommended, but it probably won’t hurt it. On the other hand, letting it run down to 0% all the time can cause it to die early.
Apple considers any iPhone with a battery capacity of 80% or above to be in optimal condition. In fact, Apple feels so strongly about battery health that its 1-year warranty covers any battery at 80% capacity or more. It’s not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above.
