Hi guys, I've had my laptop for 3 weeks and the battery life has been okay. Last night, after charging to 100%, I shut it down. Today, I was watching a stream for about an hour and came back to find the laptop dead, needing charge. I then charged it and found on the battery health 2 app that the battery is 97% healthy. It has 21 charge cycles thus far. Is this a bad sign? Should I be taking it back to the Apple store?
