I hadn't watched the video yet, but my phone's going the opposite way. It run slow charge overnight when it feels like it's going to be enough for it to be fully charged the next morning.
We really should let electronics and tight software take care of these little things.
If you'd watch the video you may realize it's not needed.
The point is that I never had to care about battery management for years. I just leave the phone doing its thing. Not that it's useful or not useful to do so.
The whole point is that I leave that in the hand of people that know.
Well not charging to 100% all the time will improve your battery life, and if you keep your devices a long time and have a usage pattern that allows charging it less like I do (I leave mine on a wireless charge pad at work), then it makes sense to make some adjustments to that particular setting.
Nah, I can't be bothered by that. And the only device's battery I really had issues with was a seven years old laptop, years ago. BMS and software will almost always know better than the user these days.
Max charge level is not something the BMS can decide for you because it's a trade off between battery health and daily charge level. That's why they ask you to choose.
