Charged mine to 100% and took it off the charger as I slept. Woke up expecting 10% battery drain... And I was shocked to see these results! I had an alarm set all night as well. LTE and wifi are always on, Bluetooth is off. Location services on, and push email is on as well.
My best battery life so far! This is awesome! It was literally HARD for me to run this down to 1%. I had to genuinely try. I took this off the charger last night at 2:35AM (or around there) and it just hit 1% at 1:11AM the next day! Almost a full 24 hours of standby with over 6 hours of usage such as games, YouTube videos, browsing, downloading apps, Facebook, twitter, phone calls, texting... The whole bit and this 6+ hours of usage was with NO MUSIC PLAYING. My previous beat battery life was 9 hours standby with 4 hours of usage. This battery life is incredible. And this is with LTE and wifi always on, Bluetooth off, location services on for many apps, and push email on with one email account. Simply incredible battery life, and, not to mention, my black/slate iPhone 5 has no defects such as nicks, scuffs, scratches, etc.
