I'm hoping someone can help me with a problem I'm having with a OEM Authentic T-Mobile Universal microUSB Battery Boost I just purchased. I bought 2 of these battery boosters from Nomorerack.com for $13.00. I figured what the hell, they should at least give me a 50% boost when I need it. The problem is after I fully charge the booster and connect it, the phone has a vibrating pulse. You can count: 1, 2, pulse, 1, 2, pulse, 1, 2, pulse, etc. When I go to "settings" and check "battery" under the General tab, it changes from "charging" to "not charging" in the same rythym pulse.
The specs are:
Slim and portable design
Compatible with most micro-USB devices
Input: 5v/500 mA
Capacity: 1700 mAh
I'm hoping its a setting or an app that's causes this. Any help would be greatly appreciated.
