For the past few months my phones battery has been lasting a few hours before it would be completely dead even after being charged all night. As of today when I charge my phone it will only charge to 75%. I have had the phone for 2 years in July. Is my phone dying to where I need to replace it or can something be done at a Sprint store to fix the issue? I have insurance on it but don't want to get a new phone since I have came to get used to this one and don't know if I would want something besides the 3D.
