    Doing that will prolong the life of your battery.

    Why? What is the difference between charging just upto 80% and 100%?

      To be honest I don’t know why. Manufacturers from Samsung to Apple to Microsoft say is the case, but I haven’t managed to find an answer with a better source than itself.

      I get the impression that it’s about staying at high levels of charge.

      For example, this page: https://support.microsoft.com/en-us/surface/caring-for-your-surface-battery-9ccdfa7b-d074-f629-425c-1c090ac66bed

      So when I go to bed I put my phone on the charger. After about 1.5 hours it is at 100%, then it spends the rest of the night on the charger at 100%. It spends 1/4of its life on the charger at 100%. From what I read of this, if it was taken off the charger and allowed to discharge, it would be less of an issue than having it at 100% then every time it drops to 99% the charger tops it up to 100% again.

      But TBH I have not found anything that backs up the idea of charging to 80% only vs charge to 100% and taking it off the charger (you can get apps that give you a notification when it gets to a certain charge level). Lot’s of people and articles talking about it as a known fact, but not so much in the way of sources.

      Because the battery is less stressed when it is in percentages near 50% than if it is in percentages near 100% or 0% AFAIK.
