Like what? When you plug it in for a long time and when you unplug it, the phone is at 93%? If that's what it is, that's normal. It's a sensor inside the phone that shuts off to prevent overcharging.
yes..I'm having the same problem. I charge my phone over night, then after I unplug it and use it throughout the day, the battery goes down and wont hold a full charge. I think I'll send it back...
