For android users, we can easily set notifications if battery level reach certain range by using apps like Tasker. Before this I set it for full charge. Change it to above 80% just now.

EDIT: tasker proj file in case anyone is interested. Link.

I know plenty of devices will stop charging when the battery is optimal and just say it's at 100% even though it's 80.

If 80% is enough, there is not much to loose that is usually where the battery health finds its plateau after some years. I rather change my battery once it hits 80% health after two years. I don't want to use it like it would behave when the battery is already dead.

Degraded battery life is rarely the thing that tanks a device for me (sure, it degrades, but it's rarely the reason I replace it). I mean it's great to know about this, but the last four phones I've replaced have been because (a) my old phone didn't work on my new network, (b) my camera failed, (c) my chipset wasn't up to the task of the most recent OS update, and (d) there was a fundamental flaw in my handset and the manufacturer offered a $50 upgrade to their newer model with trade.

Actually, thinking about it, a and b might be switched, but the point stands: it's probably been twenty years since battery life was the reason I upgraded (from a flip phone to another flip phone, iirc).

I still charge to 100, but I use a slow charger, so my phone doesn't start to spew flames while it's charging. I wouldn't be surprised if that helped as well (as heat is another battery killer).

I just can't be bothered to handle that shit manually.

I do this myself. I have mine set to 81% as the max and get a notification when it hits that level and then I get another notification when it hits 30% so I can plug it in.

There used to be a magisk module that would charge the battery intelligently and stop before b Full charge but I don't think it exists anymore sadly, or at least I haven't been able to find it
