Upgrade Phone Battery
Great Phone Battery Replacement. Likes: 1. Fits into Phone Battery location that the original Phone battery goes in. 2. Well packaged. 3. This battery is new so your phone's possible original battery "Battery Not Staying Charged As Long As It Used To Problem" is now a thing of the past. Dislikes: 1. Generally with ALL NEW BATTERIES, There is the tedious process of having to recharge and discharge and repeat to Get the new battery used to the new factor of resistance being the phone that it has been introduced to. Make sure to follow the simple instructions. Helpful
