This is just weird and I thought others were crazy when they mentioned it... Day 1: My 2150 took 2 1/2 hours for me to get the green light, I did the unplug/plug back in bump trick and the phone charged for another 1 hour before turning green again. (During this time I wiped my old battery stats) Day 2: I charged 8 hours during the night and went to work in the morning with the phone at 100%, the drive to work took just under 30 minutes, when I got there the phone was down to 92% already without being used. Day 3: (Where things get interesting) I get home from work and notice that after 3+ hours my phone is still charging, and going from 96 to 97% took about 15 minutes for 1%!!! Finally after getting to 100% (3 & a 1/2 hours with no unplug/bump method) that phone stayed at 100% for 30 minutes. Day 4: Same as day 2. 92% when I got to work after letting the phone charge for 8 hours overnight. Later Day 4: Same as day 3. Got home from work today and the phone took forever to charge (which is good) and after I unplugged it it stayed at 100% for a long time. Bottom Line: Is the battery is getting to 100% on every full charge for me, problem is if I leave the phone plugged in it seems to stop charging and in a way drain the charge that was already created. Edit: I took my phone off the charge tonight at 8pm just passed 9pm now and it is still at 100%. It's crazy that you can stay at 100% for over 1 hour, yet when you let the phone charge longer you drop from 100% ---> 92% in 30 minutes.
