dont know if this helps or hinders the conversation but: I too was noticing a reasonably high drain after the 1.1 update, but I had also installed a new widget (Facebook) on the desktop and recently had firefox installed too. In standby mode overnight, I had no connectivity other than 2g mobile, so effectively no internet but maybe some apps (facebook) and IM/SIP polling for connectivety.... In anycase, before update this was not really a problem, but now i was losing 1/4 battery overnight doing nothing. I have since removed Firefox and runtimes, Facebook from desktop and went offline from IM and SIP accounts plus set the phone to offline overnight results, still full battery when I awoke this morn. I will now start to 'turn on' one thing at a time to try to identify the culprit(s). Could be the IM/SIP polling ???????
