NXG-3D yes, according to many experts who have tested this a lot, the best for lithium batteries longevity is to always keep them within 20% and 80%. With smaller incremental charges being the best.
Between 0 to 20%, and 80 to 100% is where the battery ages the fastest (physical damage/alteration).
Letting the battery drop down to 0% is the absolute worst. And always charging it to 100% is bad as well.
Charges to 100% should ideally only be for the special cases when you know you will need it.
The settings toggle to limit the charge to 80 or 85% is one of the features GOS is still missing compared to the major brand phones.
