Generally I charge at 40% but I know you should let it drain all the way every once in a while for calibration. What is a good percentage to charge at? I know getting below 15% is bad...
Please don't troll my posts. I'm trying to make this phone as long as possible. I'm pregnant and I will be a single mother so I'm not really going to have the money to fork out for the next best expensive Samsung Galaxy phone that comes out, they seem to get more expensive each time there is a new one out, please have some respect.
I charge my phone as often as needed; it usually lasts all day. I plug it in overnight and start the day with a full charge. Once in a while I'll let my phone run down to around 20 percent before recharging.
I had an app that alerts you when you are over 80% and under 40%. I don't think there's any testing or proof to back that up, but I usually go by that. I only charge to 100% now if I know I'll be out and about and won't be near a charger anytime soon.
