These people didn’t take over half the world. The ones that conquered the ones that conquered the ones that conquered them did.

Do I understand correctly - you charge to 80%, have zero degradation, but also only use 80% of your battery at most because of that.

Your fast-charging friend, meanwhile, has been using all 100% down to 93% battery for these 1.5 years. Maybe, in a bad scenario his battery will degrade to 80% in 1-2 years and he’ll start using only 80% of his like you?

Where’s the upside in this, unless you’re both planing to use same phone in e.g. 5 years and you might get ahead in battery capacity finally?
