. Seems that my pr1.1 battery drain is the IM services. using XMPP and Skype only. My battery was draining about 30% faster than usual. In an 8 hour work day with moderate use (about 2 hours of on device time) I'd close the work day at around 70%. With heavy use, I'd close at about 50-40%. Since the upgrade, Im closing with light, moderate or heavy use in the 40-30%. On a tip from Speedevil and the ever helpful Pupnik, I stopped using the IM services, and have been using pidgin. My battery life has actually now gone up a little bit, today after 8 hours of very heavy use, I closed the day at about 40%. I was probably on the device using IM, playing Angry Birds, and updating my blog, as well as RDP'ing into 2 desktops and a server, for about 6 1/2 hours, out of the 8. Certainly a huge upgrade from the upgrade . Still looking forward to a bigger Mugen battery, thats a must have with an always connected device like this. I mean, whats another 1/4" in thickness honestly?
... anyway i thought rare but ok ... may be the battery came fully charged? ... so i continue using without problem ...
...
... may be because that battery was fully charged many times with the older OS version? ... the original battery could be charged to 100% without problem and i can get nice time of usage and both indicator show the same info ... OS and 3rd party bat indicator ..
