Battery calibration is a process to normalize or realign the battery percentage indicator on a device (cellphone, laptop, etc.) with the actual battery capacity.

Simply put, calibration battery helps your device display more accurate information about remaining battery power.

Over time and use, your device’s operating system may lose “track” of the actual battery capacity. This can cause several problems, such as:

Inaccurate Battery Percentage: For example, the phone shows that it is still 20%, but suddenly dies. Or, the battery is fully charged faster than usual, even though it is not yet 100%,
Battery Performance Declines Dramatically: Battery feels like it's draining faster than usual.

Battery calibration helps the operating system to “re-learn” the actual battery capacity, so that the information displayed is more accurate.

If you are having problems with inaccurate battery percentage or decreased battery performance, battery calibration can be an effective solution. However, if the battery is physically damaged, battery replacement is the right solution.

Here are some ways to calibrate the battery. Samsung, summarized from various sources:

Using Secret Codes (Most Common)

This method is most often recommended and is relatively easy to do.

Open Phone App: Open the “Phone” or “Call” application on your Samsung phone;
Enter Code: Type the code *#0228# on the dial pad. After the code is entered, you will be automatically directed to the “Battery Status” or “Battery Information” menu;
Pay Attention to Battery Information: In this menu, you will see various detailed information about the battery, such as battery level, voltage, and temperature;
Perform a “Quick Start” (Optional): Some sources mention a “Quick Start” button in this menu. If there is one, press it. The screen will turn off for a moment, and the phone will adjust. This process can take a few minutes. However, on some Samsung models, this option may not be available;
Charge to Full: After (or if there is no “Quick Start”, just go ahead) the above process, charge your phone to 100% while it is on. Make sure to keep your phone connected to the charger for at least 30-60 minutes after reaching 100%;
Let the Phone Turn Off: Once full, unplug the charger and leave the phone in the off state for approximately 2 hours.
Restart the Phone: After 2 hours, turn your phone back on.

Manual Calibration Without Code

This method is simpler and does not require a secret code. Here are the steps:

Use Your Phone Until the Battery Runs Out: Use your phone until the battery is completely drained and it turns off by itself;
Charge Up to 100% Without Turning On Phone: After turning off, connect the phone to the charger and let it charge up to 100% without turning it on. Keep it connected for 1 hour after the indicator shows 100%;
Restart the Phone: After the charging process is complete, turn your phone back on.

Tips for Maintaining Battery Health

Use Original Charger and Cable

Using non-original or low-quality chargers and cables can damage the battery and even pose a potential hazard.

The original charger is specially designed for Samsung devices and provides optimal and safe power.

Avoid Extreme Temperatures

Exposure to excessive heat or cold temperatures can affect battery performance and lifespan. Do not leave your phone in direct sunlight, in a hot car, or in extremely cold places.

Reduce Screen Timeout

Set the screen timeout to a shorter duration. The longer the screen is on, the more power it consumes.

By calibrating the battery regularly and following the tips above, you can maintain the health of your Samsung cellphone battery and enjoy a more optimal cellphone experience. Hopefully this article is useful!
