My net usage is usually that for 2 days, and usually get 36 hours approx between charges. I leave weather on 3 hours, sync and background data on 24/7, email/twitter set to manual haptic feedback on.
I have noticed when doing the screen dumps that suddenly under sensor (in spare parts) android system is at 75%. Never had anything under this since getting the phone, but have updated 6 apps yesterday so guessing one of them is the culprit. Otherwise partial awake and other as well as battery drain seem normal
It'd also be interesting to compare the battery model number with those experiencing issues, as a member bought an official battery and the model number differs from the one supplied, and they report much better battery life. Perhaps a batch issue with phones older than 45 days?
