I am on iOS 6.1 from iOS 6.02, iphone 5 user here...

yesterday 12pm fully charged, up until now 9.08am left 54%... did play guardian cross, fb + normal surfing... 3G for 60% with wifi off... Edge for 40% with wifi on...

much much better from my side =)

you may see my reply here and see whether is it similar to your issue...

try place your phone beside the wifi router and get the phone wifi signal at full 3 bar... i guess it will download smoothly

it is the firmware !

but i notice when it bumping around 1bar to 2bar... there is where your connection will be mess up.. and you need to on and off the wifi toggle on yr phone to get it back to work...

but a while more, it will down again...

i'm using the stock DIR-615 router given by the unifi btw... partly i think cause by the router but my other idevices are working >< iphone 5 before update also work, but after uodate then dead...

will tried once i have wifi... i doubt the connectivity problem is still unsolved yet...
