I upgraded to the new facebook last week and I must say it is an improvement in user interface, however, since I have upgraded my battery consumption has more than doubled. My normal battery loss was about 4%/hour and according to meterberry, while I left it off the charger last night and did absolutely nothing, I lost 9.5%/hour. I have switched off the chat function and still see a large consumption. Does anyone else have this issue?
As for battery life, I haven't noticed much of a difference, but considering it forced me to battery pull at least twice a day, it's offset by any improvement from 1.9.
