When im at home i have wifi on 24/7 yes, data i have turned off almost all of the time, unless im somewhere and badly need to check something and have no wifi in sight.
What i dont really get is that i have been sick for a few days now, been at home and have used the phone pretty much 100% the same both days, yesterday it was at 17% left by this time, today its around 50-55%, its not a huge deal, i mean as long as it can hold charge while im at work etc, it just goes in the charger when i get home.
Just for the hell of it i left my OLD iphone 3g on after a full charge and the damn thing lasts uses about 15-20% battery in 24h, granded thats when not using it at all, but wifi is on but with no sim card. thats still around 5 days, but then again older hardware etc etc.
Hoping for a future update to maybe fix some of the issues, but lets see!
