Download devcheck app from playstore then open it and full charge your phone to 100% then go to battery and see here ( capacity estimated % ) thats your current battery health
Yeah! You can check your Samsung's battery health like this:
1. Use the Samsung Members app (the official way). Open it, tap Support, find Phone diagnostics, and check Battery status. It'll say "Good," "Normal," or "Weak."
2. Try this hidden code in the phone app: *#0228#. It shows battery info, but not a percentage.
3. Or, use apps like AccuBattery or Battery Guru from the Google Play Store for more details.
