    I don't have lte near work so if I turn it off will it save battery and stop searching or it doesn't matter?

    It should save you some battery I recommend you turn it off since there's no coverage anyways.

    I wish it would just not search for it If there was no coverage.

    How would the phone know if there was no coverage unless it looked for it?

    Unless you live in a fringe LTE area where it may be working hard to hold on to an LTE signal over a 3G signal, I don't know if it makes too much of a difference. Since all of the radios are on one chip, I don't think the battery savings is as dramatic as it is on phones where the LTE is on a second chip. But if I lived in an area with no LTE I would probably turn it off as it could not hurt to do so.

    The answer is yes. I tested this over the last 2 days. The first picture is with LTE on all the time. The second picture is with the same exact setup except with LTE off. Huge difference. I'm assuming about 12 to 14 hours of usage with LTE off.

    Brilliant testing! Thanks.

    What have you been testing now? Any other battery saving tips ...

    Mine is on LTE all day long after I leave the house and not using even half the battery after a days work.

    I bought the 5 because of LTE, I guess if you do not have it in your area you could turn it off. I doubt it uses that much power.

    The next test will be with Locations On vs Off. I think that could also change the battery life.

    Honestly I really don't need LTE because I have wifi at home and at work which is where I spend 80% of my time. Also, just for more clarity I setup my iphone from backup. I know there has been discussions about that being the reason for poor battery life. In my case, it's not true...

    Guys, really, some groundbreaking testing going on in here.

    Next, I say we test this potentially breakthrough battery saving idea.

    Step 1: Navigate your finger to the top of the phone.
    Step 2: Prod around for the power button.
    Step 3: Depress the button until the phone displays an 'off' slider.
    Step 4: Slide the 'off' slider, turning off the phone.
    Step 5: Cook some tri-color tortellini with roasted garlic alfredo sauce.
    Step 6: Partake in deliciousness.

    That sounds pretty good actually.

    It looks like the bluetooth was on in the first picture as well. I love logical, apples-to-apples tests like this, but I think the bluetooth could account for most of the battery drain difference.

    I use Bluetooth only when I'm in the car which is a about a total of 10 min a day. I will re-test.


    Thanks, but I'm on a diet...

    3 hours 10 min usage 34 percent. 8 hours stand by. I just realized iCloud was on push so I put it on manual. Cause I only use I cloud for contacts and colander. But question is how do I access I cloud to have it push

    Your screenshots differ. In one you are on a M-Cell which relies on broadband and with BT enabled. The second you are not.

    M-Cell was on for the same amount of time each time. I come home from work at 7PM and leave at 6AM everyday.

    I suspect this will be the greatest difference. I've noticed with iOS 6 that the location icon is in my menu bar much more often.

    You can also turn off location service for just Passbook alone.
