Battery discharging while power adapter connected to MacBook Pro M1
Hi there,
I have bought an Apple MacBook Pro M1 in December 2020, and in last day I have saw some strange behaviours:
Two weeks ago, I have fully charged the MacBook and next 2 days, I have saw a drop to 99% and charging, while all this time the power adapter was connected!
Yesterday I have fully charged my MacBook and leave it with the power adapter connected(100% battery)
-today I have checked my battery with coconutBattery and that app sayd that my battery was around 90%, but my battery in mb status bar was 100%. So, I have did a restart. After restart, the battery in mb status bar was to 91% and started charging ...
How is possible to discarge from 100% to 91% in a day(24 hours, from yesterday to today) while in all this time the power adapter was connected to my MacBook? And why I have saw this drop ONLY AFTER RESTART?
It is normal ? Can someone tell me if I need to go to service or is a normal behaviour ?
This is battery health management? Maybe apple doesn't show the discharging rate (only in case of restart, like mine) to not panic users and is normal ?
