I disagree with @Sonixxone & @Eng.reham for heating part.
Initially phone was not heating that much. But from last 3 days I’m facing the overheating issue. Phone ideally stays between 38 to 40 degrees. Just after normal usage. That’s weird. Already shared feedback with Nothing. Battery backup is good. Lasts 1 day. SOT 8.5 hours, +/- 1 in some cases.
