Turned off Wi-FI (and uninstalled BatteryGuru) after leaving for work today at 0730h (Airplane mode activated throughout the night and so active cycle from 0630h and I pulled in about an hour of screen on time by 0900h.
Again, I did not touch the phone much from 1000h - 1200h and the drain was ok as evidenced by the graphs attached. For some reason the standby drain in the afternoon got a little bit worse but I ended up pushing the phone to less then 10% past 2000h which is an improvement.
I suppose that my leaving the phone untouched for long periods of time (such as between 0900h and 1130h) has kind of helped but there is still a reasonable amount of drain. I will do a factory reset and hold tight for the 4.2.2 update, otherwise it's just a matter of being judicious with usage in order to make till the evening, which is easier said than done with this beautiful handset
