If you’ve been using Samsung phones and tablets for years, you might be familiar with the secret code *#0228#. By checking it, your mobile battery information has been restored to the operating system (Android) or as many say “battery fixed”. However, this option is no longer available for some time, especially since Android 13 (One UI 5).
Hence, many users have found that they cannot reset their Samsung Galaxy battery data, among them you are definitely there. Fortunately, there are still two solutions and we will explain why * # 0228 # does not work and how to fix your Samsung Galaxy battery.
*#0228# doesn’t work on Samsung Galaxy since Android 13, but does it fix the battery properly?
As we mentioned in the title and a little earlier, starting with Android 13 this special Samsung dialing code doesn’t work. *#0228# simply disappeared, no obvious reason why, but Samsung moved the option to another location where it is also accessible with a special dialing code.
In the following sections, we will tell you what the new code is for measuring your Galaxy battery, as well as another less orthodox option to find it. But, first we want to talk about the myth.
Both the dial code *#0228# and the new methods will never “calibrate” your mobile battery. Many believe that by activating this option, the battery is reset and starts charging properly. Moreover, rumors have spread on various forums that the battery has been renewed or the health (which is another thing) has even improved as if out of nowhere, the autonomy has increased.
What *#0228# did and the new methods continued to work was to delete the Android “batterystats” file so that the operating system could be rebuilt from scratch. This It allows Android to display the correct battery percentage. Something left on your mobile, out of control over time. Let’s look at a famous example…
Do you experience that your phone is charging 100% and draining quickly? This is what can happen.
If you have a slightly older cell phone, you may have experienced charging it and it will charge from 20% to 100% in no time. This would be fine on a very fast mobile phone but it is not the case because we are talking about an old device.
Then as soon as you see that the phone is 100% charged, you disconnect it and wonder if the battery is at 40% or 50% after a while. Yes, the battery can be bad, but often this is not the case.
Maybe what happened there is that the “batterystats” file is not working properly. So this tells the operating system to go from X to Y percentage of load from one instant to Y without having the actual value. When it reaches 100%, the load will automatically stop and that’s it The battery still has a lot to charge..
Deleting the file will help reset the settings, but you need to know how to do it and we will tell you below.
Here’s how you can fix your Samsung Galaxy battery on Android 13 or higher.
As we have already said, there are currently at least two ways to rebuild the “batterystats” file of your Samsung Galaxy mobile. We’ll explain them, but you’ll need to follow all of these steps below to make it work.
Charge your mobile phone fully. Dial the code *#9900# in the call app To enter the SysDump menu. There, scroll until you find the “Batterystats reset” option. Press it to delete the file and rebuild Android.
Method 2: Turn off your phone and enter your Samsung recovery Press the Power + Volume + Bixby buttons at the same time. When you enter the recovery, look for the “wipe cache partition” option and execute it, then reboot your device to make sure the charging percentage is set correctly and enjoy.
In both cases, the Android “batterystats” file will be deleted, although deleting your Galaxy’s system cache will remove many more files in addition to the recovery wipe. Don’t worry, you won’t lose any settings if you do this. On the contrary, you can fix other small problems that you may have.
