    MBP 2015 battery drops from 50% to 0%?

    I recently bought a 2015 MBP from a private seller. The battery says it only has 4 cycles which leads me to believe they put a new battery in before selling it (I vaguely remember them saying something about this): It's been running fine (mostly in clamshell mode/plugged into power) but today...

    Aluminium PowerBook G4 15"—borked battery information

    14" MBP battery already dropped to 99%

    It's only got 21 cycles on it and 2 of them were already there when I got it. Coconut battery fluctuates between 95 and 97 but the system report now shows 99%. How could a brand new laptop battery drop that quickly with only 21 cycles? Anyone else seeing this?
