Re:Charging a lithium battery to 80% only? by tjoff on Tuesday November 21, 2023 @05:08AM (#38361687)
But that 20% that makes all the difference will only make a difference when the phone is new.

Otherwise the opposite is true. Refraining to charge fully makes all the difference and saves you from a tough spot.

Which in turn is why (was a bigger problem before) the sentiment that it doesn't matter how good/bad battery life I have as long as it lasts me a day. Well, if you do a complete cycle every day a year old phone will not last a day anymore...

This used to be an easy problem to fix, by replacing the battery.

Shame that seems to be harder and harder to find on new phones.
