Seems like something not right, almost a week and my Nothing Phone 2 consistently have idle batt drain at night of average 11%.
I have DND and sleep standby optimisation turned on. In the morning when I check under battery usage details, no info is available.
I will turn off DND and Sleep Standby Optimisation today and see how many % batt drain tomorrow morning. Hopefully I can see which apps are draining power during the night with Sleep Standby Optimisation turned off.
Quite frustrating to see such significant batt drain every night. Factory reset will be last resort as Internet banking apps are a pain to setup all over again.
