    Trying to "calibrate" the sensors which you apparently need to let your battery die then charge it again to get. So what's the fastest way besides the usual turn on every radio max brightness push notification stuff?

    Play some intensive games or watch some videos. That'll do the trick.

    Play Infinity Blade 2 then Infinity Blade 1 proceeding with music at full volume.
    Run more games and shut the device down.
    Turn it on again. Text a bit...

    haha now that I actually want to drain my battery it goes slow. Why when I need to use my phone the battery drains like a **** but when I want it to die its like 11% every 30 minutes

    GPS sucks battery life down pretty quickly as well.

    What I've noticed from laptop battery conditioning, is that you aren't going to get a good calibration if you're purposefully running the down the battery as fast as you can. You want to calibrate for your normal use cases, not for artificial loading.

    Take a video with flashlight and use GPS in background with a tracking app, and/or use 3G or LTE, especially if you have a bad connection.

    You can drain a full battery in 2:30 when video recording. And unlike a game, you don't need to actively be doing anything with the iPhone.

    Try FaceTime. That sucks my battery down to 0% within an hour.

    And calibration isn't affected by how quickly you discharge the battery. All you're doing is syncing the battery's actual charge and its reported charge by providing a baseline 0% charge level.

    after 3 hours of max brightness, all radios on, multiple videos, graphic intensive games, video recording, and texting/instagram my battery finally died. God damn Apple.

    This. Your iPhone will only last around 1-2 hours (from a full charge) if you leave your flashlight on.

    I find making calls runs it down the fastest, or a close second is 3/4g intensive browsing, downloading lots of pages/pics fast, and using the camera seems to use a lot of power.

    Come to think of it wifi browsing and music are about the only things that don't. :)

    Funny, my 5 was averaging a good 8 hours of actual usage, ie. no music, lately it's more like 7, not sure what changed. But hey, 7 is still pretty decent.

    And you know, If I'm spending more than seven hours on the phone in one day, my problems are probably not so much battery life, but actual life. :)

    Ah

    Find a spot distant from your city that is also distant from two towers. The resulting "distant tower reception battle" will cause your phone to keep renegotiating the cellular connection over and over and you'll not have much battery life left.
