So I have a couple month old OnePlus N30 phone, and one thing that drives me crazy with it is when I plug it in at night to charge, eventually it fully charges. You would think this is good, but then it decides to vibrate every 30 seconds or minute or so to tell me it’s fully charged. Over and over again till it wakes me up and I unplug it. So far it’s still mostly charged by the next morning but this is ridiculous - aren’t you supposed to charge the phone overnight?

I tried just turning off the notification but the phone is using the system UI to notify and won’t let me turn it off.

Does anyone know how to stop this?

    except that manufacturers account for that and calibrate such that what you think are 0 and 100% are actually closer to 20 and 80% respectively.

    It’s actually the other way around. A safe cutoff voltage to prevent battery degradation is about 4.2V, but most modern phones charge until 4.45V, so they can advertise a bigger battery capacity at the cost of long term battery health. Your phone essentially charges itself to more than 100%
