I saw a few posts on battery life on the iPhone 5, my question is how do you measure battery life accurately? the battery will obviously decrease when running different apps/browsing/checking email so it's forever changing, I've used my iPhone today for about an Hour listening to heart radio and every 2-3 minutes I notice 1% decrease, same when playing music, checking email, those apps are off , just normal use it doesn't decrease as much, I think it's a bit crazy to expect your phone to last 8hrs plus if you are doing any of the above off and on....
