Hi,

Generally I think my M1 MBP battery is performing just fine. I have, however, never drained my MBP completely or below 10% until today. I have managed to get more than 17 hours (nearly 18 hours) of on-screen time from full charge and about 8% of charge still remains. However, I have noticed that once the battery had reached 17% it started to lose charge during sleep intervals rather quickly than usual. Force instance, I left my MBP for sleep with 16%-17% charge for an hour or so and came back 13% charge remaining. A little later I left my MBP to sleep for an hour & half or so with 11%-12% charge. When I woke it up it had 8% charge left. Losing 2%-3% charge is normal for my MBP but that happens during prolonged sleep, at least 8 hours. I have generally not noticed any drain during short interval sleeps. Has anyone noticed quick drain with the last 20%-10% charge remaining?
