8246 mAh after 34 cycles on my 16" 2019 MBP. That's a lot worse than I expected.
What's the best way to slow battery degradation if I use it for 8-10 hours daily for work? Run MBP from an outlet and do full discharges once a week? Run MBP from the battery and recharge the battery when it depletes? Run MBP from the battery, but charge it only to 80%?
- geoelectric 7y agoAt this point, I think anything you do is going to not be better than what the system could automatically do for itself. Their change will basically give you that 80% bit. There's something to be said for occasionally running the battery down to zero and charging it all the way back up, of course, but I wouldn't think of it as an effective regimen with current battery tech. I'm also not sure how quickly it's expected to drop in capacity. IIRC, batteries drop a notch when they start getting used, plateau there for a while where it mostly depends on environment (try not to charge them when it's 110deg ambient, for example, overheating will kill a battery fast); then eventually drop again and start heading on down. And, of course, all of this scales by how cold it currently is ambient because lithium batteries have reduced charging capacities cold (though I don't think it damages them permanently like heat does). For all I know, 95% (roughly where you're at) is the expected amount once all factors are concerned I wouldn't worry too much. Maybe just get some comparative specs on MacRumors or with one of the utilities (some benchmark against everyone else iirc)
