How to Calibrate the battery of your Android Phone step by step

Do you feel like you’re running out of charge faster than ever when you use your cell phone? Is the battery draining faster than it should? If so, calibrating the mobile battery is the solution.

Calibrating a phone’s battery can help maintain its life over time and provide more accurate readings of remaining power. We’ll explore ways to properly calibrate your smartphone battery, as well as strategies to extend its life with proper use and maintenance.

How to calibrate the mobile battery step-by-step

The battery life of mobile phones changes over time and it all depends on how it is used during its useful life. The changes to which the battery is subjected can cause it to go out of calibration. That is, a percentage of energy is shown on the screen that is not the real one.

In other words, if you see that your device turns off when reaching 10% or significantly decreases power after a percentage, you need to calibrate the battery. By doing this, you can determine how well the life of this component is going.

Calibrating the battery is not difficult, since it involves carrying out a full charge in a strict manner. Next, we explain how to do it on Android. And if you have an Apple mobile, don’t miss our post on how to calibrate the battery on iPhone.

How to calibrate the battery on Android: the basic method

The classic method to calibrate the battery of your Android phone is as follows:

  1. Wait for your phone to discharge and turn off automatically fully.
  2. Do not charge your phone or use it for 6 hours.
  3. After completing the 6 hours of rest, connect the device to the charger and wait for it to reach 100% power.
  4. Once it has reached the maximum charge, you have to leave it connected to the electrical source for 2 more hours.

At this point, you can disconnect the phone and start using it normally. Your battery should be working properly. How to charge your mobile properly is key in this method.

How to calibrate the battery on Android with applications

If you find the previous method tedious and want to save steps, then you can use an application to perform battery calibration on Android. One of the most recommended is Calibrate and Repair Battery, which analyzes and stabilizes the battery quickly. To do this, you have to follow these steps:

  • Download and install the application.
  • Open the app and click “Accept” if it asks for permission.
  • Then, click “Start”, which is at the bottom of the screen.
  • Wait for the analysis to complete and click “Repair”.

This will help balance the ionic cells of the battery so it can be calibrated. Ideally, you should keep this application on your mobile to be aware of all the problems that may arise with your battery. It is recommended to do this at least once a month.

How to calibrate the battery on Android with root

There is another way to calibrate the battery on Android with the Root Explorer app, but it is a method recommended for advanced users only. The first requirement that you must meet is to have your Android rooted. Then you have to follow these steps:

  • Apply the first method of discharging the battery and recharging it.
  • Turn on your phone with the charger plugged in and keep it that way.
  • Download the Root Explorer app.
  • Enter Root Explorer and look for the “Data” folder.
  • Now, click on the “System” folder.
  • Delete the file named “batterystats.bin”.
  • Unplug the charger and wait for the phone to discharge until it turns off (you can use it normally while it discharges).

When it turns off, connect it to the power source and wait again for it to reach 100%. This way, your Android will get a deeper calibration and will last longer than the other methods.

It is important to note that both this and the other ways to calibrate that we have mentioned so far, work for all Android devices in general.

Calibrate the battery on Samsung: How does *#0228# work?

If you have wondered how to calibrate the battery on Samsung, one of the most commonly used methods is with the code *#0228#. It works in the following way:

  1. Charge your phone to 100% and disconnect it from the charger.
  2. Then you have to open the calling application.
  3. Write the code *#0228# and click on the call button.
  4. The “BatteryStatus” menu will automatically open and you must click the “Quick Start” button.
  5. If a warning window appears, click “OK”.
  6. Now, restart your device and check if the battery percentage remains the same as before. Otherwise, carry out the process again until it remains at 100% when it restarts.

If your battery has maintained exactly the same percentage of energy, it is already calibrated.

How to know if the battery is calibrated?

There are two ways to know if your mobile battery has been calibrated correctly. The first is to go directly to the “Settings” menu and look for the “Battery” option. If you go there, you can see detailed information about the current and historical battery usage.

On the other hand, the second method is using a third-party application which, in this case, the most recommended is AccuBattery. Best of all, it is very easy to use, as you just have to open it to see the actual percentage of the battery capacity and compare it with the power system indicator on your phone.

Why is my battery not calibrated correctly?

Have you already learned how to calibrate your mobile battery? If you have been successful, the next step to extend the useful life of your device is to know all those causes and bad practices that can cause a malfunction of the battery, or in other words, a decalibration of it.

Now, what is an uncalibrated battery? Well, the main characteristic of a decalibration is the error in the charge percentage, that is, what we see on the screen does not correspond to the real remaining percentage.

For example, the mobile phone may indicate that it has 60% left but it actually has less than 10%, so the battery suddenly drops in a few minutes and the terminal ends up turning off. A circumstance that can give us more than one annoyance, especially if we are doing something important.

Among the most common causes why our battery is out of calibration, we find:

  • Unsuitable ambient temperature: extreme temperatures can seriously damage the mobile battery. Without going any further, Apple warns on its website that its devices reduce performance if the temperature is lower than 0ºC or higher than 35ºC.
  • Battery overheating: certain chargers can cause the internal temperature of the mobile to increase disproportionately. As far as possible, always follow the manufacturer’s instructions and use an official charger in good condition. On the other hand, it is also highly recommended to use breathable covers.
  • Poor coverage: When the device is in an area with poor coverage, the battery exerts greater effort. If this happens regularly, the chances of it going out of calibration are much higher. In these cases, you can activate airplane mode.
  • Excessive consumption of some apps: in some cases, they can use a lot of mobile resources and drain the battery faster than normal. Check which ones consume the most or are in the background. It is a good trick to save battery on your mobile.
  • Outdated applications: Old versions of apps consume more battery and affect their functioning. It is important to update apps on Android and update apps on iOS.
  • Bad practices in mobile charging: fast battery charges usually cause greater degradation and decalibration of the battery. In this sense, the charges should reach a maximum of 80-90% and not be carried out before reaching the remaining 15-20%.

It must be taken into account that this degradation is inevitable even if the preventive measures mentioned are strictly followed. For this reason, we insist on the need to recalibrate every 1-2 months to ensure the proper functioning of the device.

However, the calibration process has a limit, since the longer the device is, the more it will cost us to fully recover the mobile battery. It’s a matter of shelf life, nothing lasts forever. Electronic components are no exception.

How to calibrate battery on Android: frequently asked questions

Although calibrating the battery of a phone or tablet is relatively simple, you may have questions in the process. However, you don’t have to worry, since in this section you can find all the answers to your questions.

What happens if I calibrate my Android battery?

Whether you have to reset the battery on a Xiaomi or calibrate the battery on a Huawei, your mobile will always benefit. Calibration will force your device to discharge and charge back up to 100%. This helps align internal energy levels with the levels displayed by the operating system.

If you haven’t calibrated your battery for a long time, you may have noticed a decrease in its ability to stay charged or an incorrect percentage of power displayed. For example, if your battery reads 80%, but is actually discharging quickly, then you need to calibrate it.

What is battery calibration?

Battery calibration is a process that seeks to synchronize the percentage of energy with what is displayed on the screen. This is a simple task, but crucial to preserving the life of your battery and ensuring you have a great user experience.
