Good question - I'll check that out as I don't spend much time surfing; what I also notice is that I'll lose 2-3% for a 10 minute phone call as well...
In my experience there seems to be day to day inconsistency with battery life.
My experience has been if your phone is searching for WiFi it can run the battery down some too. You might want to turn that off when you are out of the house and stuff. Also, do you have anything like Skype running? I have heard it can use battery as a multitasking app, but I am not sure.
Wait until some charge cicles... Its tends to get better after the first weeks or so. Its very rare to have an faulty lithium battery. You´re probably OK
Everything uses battery life. I know people want to maximize it, but if you turn off everything, what is the point of having the phone to begin with?
Some of us are just curious as to which apps/processes drain battery life faster than others...for those of us who spend a good part of our day out & about without a charger, this sort of thing is definitely of concern.
Most battery problems are not necessarily anything wrong with the phone. When you are worried about the battery, how often do you unlock the screen to check the battery status? This screen drain alone can be a issue. I know when I first jailbroke, my battery took a HUGE dive. Of course this was because I was on the phone a ton of the time downloading and installing crap.
No I mean in standby it will sap the battery within a day. Normally we can go 2-3 days of him watching a movie hear and there or Netflix for a couple hours. But with Angry Birds in the background, especially when he opens 2 or 3 versions the battery is dead from a full charge by the end of the day.
