Exploring Two Alternative Methods to Calibrate Your Samsung Phone Battery for Extended Longevity

If you've been using Samsung phones and tablets for a while, you probably know about the secret code #0228#*. This code was traditionally used to reset your phone battery to factory settings, known as "battery calibration". However, since the release of Android 13 (One UI 5), this feature is no longer available.

Many users are now facing difficulties in resetting the battery data on their Galaxy phones. Fortunately, there are alternative solutions available. In this article, we'll discuss why the #0228#* code has ceased to function and explore different methods to calibrate your Galaxy phone battery.

With the introduction of Android 13, Samsung has discontinued the functionality of the #0228#* dial code. The exact reason for this change remains unclear, but Samsung has moved this option to another accessible location using a different dial code.

In this article, we will guide you through the new method for calibrating a Galaxy phone battery, as well as a less conventional alternative. It's important to clarify that neither the *#0228# dial code nor newer methods actually "calibrate" the battery. The common belief that activating this option resets the battery to charge correctly is a misconception. There have been rumors circulating in forums suggesting that this process extends battery life or rejuvenates it, but these claims are not accurate.

What does the code #0228#* do?

The purpose of *#0228# and similar modern methods is to delete the "batterystats" file in the Android system, allowing the system to regenerate it. This ensures that Android accurately displays the remaining battery percentage on your phone, which can become less accurate over time. Consider a common scenario...

Have you ever noticed your phone showing a 100% charge, only to see it drain quickly afterward? This is a typical issue.

For users with older mobile phones, you may have observed rapid charging from 20% to 100%. While this is advantageous for fast-charging smartphones, older devices may not experience the same benefits.

After charging your phone to 100%, if you unplug it and notice the battery percentage quickly drops to 40% or 50%, the problem may be related to the battery itself or the malfunctioning "batterystats" file. This often results in inaccurate readings, where the phone shows 100% charge but the battery isn't fully charged.

What is the "batterystats" file?

Resetting this file is essential for restoring settings, but it's crucial to follow the correct procedure, which we'll outline below. Here's how to calibrate the battery of your Samsung Galaxy device running Android 13 or newer.

Currently, there are at least two methods available to recreate the "batterystats" file on your Galaxy phone. To ensure effectiveness, follow these steps meticulously:
  1. Charge your phone to full capacity.
  2. Once it reaches 100% charge, keep the phone connected to the charger for at least an additional half hour.
  3. Without disconnecting the phone from the charger, proceed with one of the following actions:

First method:

Dial the code *9900## in the calling app to access the SysDump menu. Find the "Batterystats reset" option and tap on it to delete the file and rebuild it by the Android system.

Second method:

Turn off your Samsung Galaxy phone completely, then enter Samsung's recovery mode by pressing together the volume up and power buttons or the Bixby button. Once you are in recovery mode, find and execute the "Wipe Cache Partition" option, then restart the device.

When using either of the mentioned methods, the "batterystats" file in the Android system will be deleted. However, if you delete the cache of your Galaxy device's system, it will also remove many additional files. There's no need to worry, as you won't lose any settings by doing so. On the contrary, it may help you resolve other minor issues that may arise.
