okay... heres my issue... i have my droid ultra i just bought it in last april so its only 7 months old and its doing this weird thing where it dies and will come back on saying it has a charge but than dies again and the cycle is continuous... i dont really understand ive read forums and they say there is blockage but ive looked and there is no blockage... and ive tried numerous different chargers and as soon as it DIES again it says its charging... wtf?? HELP!
