few months back I read the battery health from samsung battery health check using some codes. it showed 98% or 96%. Accubattery showed 89%.
Here's how:
*[Extensive Guide]*Check Your battery Health and Cycle Count on Samsung Devices
I have Checked Mine,
88% battery Health and 462 battery cycle count; bad for 1.4 year S23 i would say
Step 1: Dial *#9900# It will open SysDump (If the code is not working turn off Auto Blocker and Try again)
Step 2: Tap on Run dumpstate/logcat ( It will take 2-3 minutes be patient wait until its done, click ok after its done)
Step 3: Tap on Copy to sdcard(include CP Ramdump) ( Wait until done, click ok afterwards now you can close the menu)
Step 4: Now go to PlayStore and Install LogLog App
Step 5: Open the app click the bottom right corner icon go to your Internal storage there will be folder named log,
Go inside the folder scroll till you find file named dumpState_S911 tap it. (Note if your are confused here that S911 after dumpState_ is my model number. In your case your modelnumber will be there so its like dumpState_<yourModelNumber> hope you got it.)
Step 6: When inside the log file there will be a search option on top Search mSavedBatteryAsoc
Thats it mSavedBatteryAsoc will show your Battery percentage and mSavedBatteryUsages will tell your Battery cycle count. The number shown in BatteryUsages will be like 33248 you can take it as 332.48 battery cycle count.
