I can say that it did pretty good yesterday as I was either at home or with a decent signal.
I did see where a lot of battery was used by Facebook. I disabled allllll of the push notifications. They were all checked.
Facebook was the number one power user on the battery screen.
I think that'll help a lot.
But, like these other guys said, I don't like to 'baby' this phone, but I tell you if I left location on, all those push notifications, syn, mulit window, full screen power, I seriously doubt I'd make it all day.
Again, especially since I work in a basement and it's searching all day for a signal down there.
It does say Android system is the most battery using. Not sure what all that entails.
Also, I remembered that it said some 'cloud' service (either Google or Verizon, it was VZW I think) was full the day after I got the phone. Not sure which one it was, but I told it ok.
I wonder if it's trying to upload something in the background to a service that's full.
I guess in that case, it'd be giving me warnings still.
