If my phone powers off due to no battery power, I occasionally will then have issues with it then charging and working correctly. If it is plugged in to the wall charger and the battery is in, it just continually cycles through the startup process and never stays on long enough for me to do anything. However, if I take the battery out, the phone works fine. Normally after several hours or so the phone charges fine again when I reinstall the battery but it's been a couple days this time and still no success. I haven't taken in to the store yet but I'm wondering if a factory reset might be the answer. Has this ever happened to anyone else?
