That chargie device is interesting!

The latest versions of Android and iOS have finally built in battery management that does basically the same thing (they will not rapid charge over night, and will sometimes limit charge below 100%).

I'm curious to see long term how much these changes will help.

Android, Samsung lower mid-range phone: set to maximum 85% charge thru the OS was a nice find in the menu.

Yep, called "Protect battery" or similar. Lots of phones have it, even quite old ones.

The Chargie is also useful if you want to set an arbitrary charge limit. iirc on Samsung you're stuck with 85%, can't change it.

Another key thing for the Chargie is that it will cut power after reaching its requested charge, and only resume charging again if power falls to a certain level. This prevents the "trickle charge to maintain the precise percentage" thing that is a real killer for batteries.

Latest version of LineageOS has a setting to limit charing up to a certain %, but also makes sure it hits the max when you wake up (based on your alarm).
