I have a nook HD and my brother broke the wall port so I have been using a Samsung but the nook was 2amp or voltage or something but the Samsung is .7 and I noticed when I use it dies after just 3 hours when it use to last 7 or 8 is this permanent and will the new charger if I buy one restore the battery.
