Is Fast Charging Killing the Battery? A 2-Year Test on 40 Phones (www.youtube.com)

TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.

And with that, hopefully we can put this argument to rest.

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.

    Who's doing the asking there? Neither my laptop nor my phones asked anything.

    According to the settings on my current phone, the automatic setting will decide by itself to limit the maximum charge overnight, then plan to go full charge around the time my alarm should fire.

    But, again, that's the kind of micromanagement that would yield a tiny fraction of "maybe improvement" over the lifetime of the damn thing. I'd rather have a device works all the time for 6 years than have a device that's sometime undercharged for 6.1 years.
