I’ve read many articles suggesting that batteries should not cycle from 0-100% regularly, but keep them always around 80% and put them down to 20-40% before recharging them back .
I have also read that charging to 100% and being at 100% is also bad because it damages the life of the battery faster. Furthermore, I know many people who set charging limiters to avoid going up to 100% and keeping their batteries at 80%.
Personally, I have tablets and laptops running almost all day, and I always have them connected to the power cable.
But I always had one question:
It is better to keep cycling their batteries from 80 down to 20% and back to 80% all the day through?
Or it is better to install some software to set the charge to 80% and keep it there permanently with the power cord.
