Just got my HTC One. Looks like I will have no problem making it through a full day on one battery charge. I always charge my phones over night. My question with the One is whether I should be having the One plugged into a charger during the day? I'm near an outlet almost all the time. What is the best for Li-Poly batteries? Should I try to only charge when it gets below a certain percentage? Or is it OK to drain it down to say 75% and then charge it back up again?
