How to Calibrate Battery on Android Smartphone

Learn how to calibrate the battery on your Android smartphone to improve its performance and accuracy. Follow these simple steps for better battery health.

Surely you have encountered a situation when the smartphone still has about half of the battery charge left, but it turns off on its own. This is due to a decrease in battery capacity. This phenomenon is quite typical for all modern batteries in gadgets, since with age, certain chemical processes occur in them, leading to their degradation.

Sometimes the problem can be solved at the software level. There are often situations when the system indicates a level that differs from the actual battery charge. In many cases, this “reading” problem leads to a reduction in the duration of a full charge. Here it is worth trying to calibrate the battery so that the system correctly determines its remaining capacity. At least this way you will not get into trouble and will not be left with a discharged phone due to incorrectly displayed percentages. And the calibration process itself will definitely not harm your smartphone.

When is battery calibration necessary?

If your smartphone is discharging abnormally quickly, and the battery percentage is “melting” before your eyes, you should at least try to calibrate it. Here you need to consider several factors:

  • The phone is no more than 2 years old;
  • You don’t load it with a bunch of background applications (messengers, games, navigators, etc.);
  • You have the latest firmware version installed for your device.

It is also worth paying attention to the following behavior that is not typical for smartphones:

  • The indicator shows a conditional 2%, but the device works for several more hours;
  • Charging does not reach 100%, but ends at a conditional 95% (if the charging limit is not enabled in the settings);
  • After disconnecting the smartphone from the power source, the charge immediately drops by several percent.

Google experts have encountered similar user problems more than once, so they have developed a short instruction on calibrating batteries in Android smartphones. It works in 99% of cases.

Here’s how you can perform the battery calibration procedure on Android:

  • Charge the device to 100% and leave it to charge for another 2-3 hours without using it;
  • Disconnect the charger and use your smartphone as usual until it discharges to 0% and turns off;
  • Charge it again to 100%;
  • Repeat the cycle 2-3 times.

That’s it! After a few cycles, the system will recalibrate and start displaying the battery level correctly. It is very important to use a high-quality charger and cable, and to prevent the smartphone from overheating under any circumstances. If this does not happen, then you should contact the service center for diagnostics and possible battery replacement.

How to Calibrate the Battery on Samsung Galaxy Smartphones

Unlike many other vendors, Samsung has provided a software feature to calibrate Galaxy smartphones. However, it is hidden in the engineering menu. Here is how to use this option to calibrate the battery on Samsung devices:

  • Discharge your phone’s battery to 5%;
  • Open the Phone app and enter the code *#0228#;
  • Click on Quick Start in the pop-up menu and confirm the action;
  • Wait for the display to turn on again and check that the battery percentage has decreased;
  • Charge the device to 100%, then disconnect the charger and reboot the smartphone;
  • Open “Phone” and enter *#9900#;
  • Scroll down to the BatteryStats Reset option and tap on it;
  • Exit the menu and reboot your smartphone.
  • Exit the menu and reboot your smartphone.

Done! You have successfully calibrated the battery in your Samsung smartphone. It is worth noting that not all Galaxy devices support these commands.
