On a Samsung Galaxy phone, go to Settings > Battery and Device Care > Diagnostics > Battery Status to check your battery health. On other Android phones, dial *#*#4636#*#* in the phone app or download a third-party app to check your battery health
Whichever method you use, the result is the same: you get to check your phone or tablet’s battery health. As mentioned earlier, unlike iOS, you don’t get to see how much the battery has degraded with time in percentage points, but we can keep our fingers crossed that is something Samsung will bring over with future versions of One UI
In samsung member app , tap the Support button at the bottom of the opening screen, tap the View tests button, and then select the Battery status option there.
