is the battery life better on iPhone 5 compared to iOS6.0.2?

yes you can

i realized that on iOS 6.1, battery drains faster than iOS 6.0.2 anyone experiencing the same?

i charged my phone to 100% before going to bed at 2am.
woke up around 9am and only left 60%
3G was on but no notification, what could be the cause of the battery draining?
it wasnt as bad when i'm on 6.0.2

that doesnt answer my question, as i stated on 6.0.2 i did the same but battery didnt drain as bad as this.

if i do that, it already shows that iOS 6.1 has worsen the battery life.
im making comparisons base on exact same settings and user use on iOS 6.1 and 6.0.2

nothing to do with settings.
like i mentioned above, im using the same settings as i did on iOS 6.0.2
but my battery drained less compared to iOS 6.1

maybe its because you upgraded, try doing a restore next time when you want to update iOS
then restore back up

discussion is about iPhone 5, not iPhone 4.
unless you did a typo
