Just got my Atrix 2 weeks ago and it has been randomly shutting off, with no way to turn back on, other than a battery pull. It happened twice yesterday, two battery pulls- also battery was dead by 3pm. Woke up this morning- full charge, same thing- phone shuts off- battery pull to get it started again. So far I am not impressed with the batter life- I can't get through the day with a charge. Any ideas?
