How......
I don't play with it all day in all honesty
I'll give you a rundown of my current stats.
since unplugged - 1d 12h 36m
Display 47% - 2h 7m
Maps 17% - CPU 3m1s GPS 40m
Cell Standby 15% - 1d 12h 36m
idle 14% - 1d 10h 28m
Andriod system 3% - CPU total 12%
ChompSMS 2% - CPU total 8m17s
Voice calls 2% - 1m39s
I have played some games on it too but not a great deal hence they don't show up on the stats.
As i said previously, my usage isn't typical for others smartphone users, its just typical for me. I work at a desk all day with a computer that has no restrictions on the internet, at home i have my PC and my Macbook Air. My phone also isn't syching emails and facebook all day since i'm at the desk. If i get an email i'll pick it up when i check or when i get home. If it was that important people would have called.
I have a smartphone because its very handy to be able to check the web for a restaurant or use the maps or whatever which I can't do on a normal phone.
I DON'T have a smartphone so that I can watch episodes of tv on the train, twitter my life away every 3 minutes and play games all day etc.
I'm also not a massive social monster. I have a phone at my work desk and a landline at home. I use my mobile for calls if I'm out and about or if I'm calling a mobile and am not at work.
It's best that i don't do phone reviews, they'd all get 5* from me for battery tbh lol.
