Pixels can be configured to limit charging to 80% these days.

I’ve started using it and the difference between using 80% and 100% on a daily basis is negligible, I rarely if ever let my device go below about 35% anyway. So this change is basically free battery life for the device

Samsung have a setting to set the charger to only charge to a certain amount over night

So if you plug it in at 1800 at 0230 or whatever it won’t be charging until just it calculates that it will be full charged when you wake up
