firstly no one is a liar.
Secondly my usage time Doesn't go up 30 mins every 7hours of standby like yours does, if I leave my phone for 7 hours on standby usage time probably goes up a few minutes at most.
Thirdly I use my phone indoors mainly and 30% brightness is about right for the lighting indoors, 50% brightness is way too bright unless your in sunlight!
Next time I need to use my phone for 10/11 hours straight out of 13/14 hours I'll post you a screen shot as evidence ok
.. until then I couldn't care less if you believe the usage Im getting or not fella.. it's just doing slightly less than Apple says it can do
Cheers
Ps it's not a competition
.. so don't feel threatened
