Macbook pro battery charging matter
The MBP (15", 2018, Sonoma 14)) never leaves the desk, so is always connected to the electricity power. The battery level stayed at 100% all the time. Lately, I started shutting off the MBP every night, and it stays unplugged for ~10 hours. This had been going on for ~ 2 weeks. Lately, the MBP started decreasing the battery power to 80% and leave it like that the whole day. I go out, just close the lid, come back and it is still at 80% - charging on hold. Now, if I shut down the MBP at night, and the next day, the battery level is still at 80%, but but itwould say that it will be charged to full by 10:30, and that happens. But, after a while, a few hours later, it goes slowly back to 80% and stays that way.
By the way, this MBP never gets heated up, I never hear the fans, except when an update is going on. There are few apps working, quite a lot of tabs open etc. Cool at touch and so on. battery cycle is at 207. It was bought in mid 2019.
Yesterday, I left it on all night, that is the lid closed, the MBP sleeping for ~10 hours. The battery level is still at 80%, charging on hold. I think, I'm going to keep it this way (always plugged in, but not shutting off, sleeping at night) till next Sunday, and then use it on battery the whole day on the Monday after, to give the battery some work experience, and then continue to use it for the next month always on power without shutting it off. And, give another full day's work on battery after that month.
Any thoughts? Thank you!
