I'm never using my device in such mode. I always have wifi is on, 2G/3G/H+, location services is on, 2 gmail and 1 imap (inbox check frequency - every hour), skype, icq, social networks etc etc... and for me the most important is the battery drain index when screen is off. On r141 (with my settings) it's about 0,5-0,9%/h.hi
what about deep sleep does r141 works well, i just got 4% drop with r135 in 24hrs
