    I've disabled LTE on mine and will use it like I normally do throughout the day to see if it goes any better.


    I initially was doubting that LTE may have had anything to do with it because here in Brisbane, we only have one provider with LTE (which I am on) however we only have coverage in major areas. I was noticing my battery life was pretty bad at home which is a 3G area only with no overlap of LTE so I figured the phone would have been sitting on 3G without using much power for the LTE related components (just the occasional check or thereabouts).


    It could possibly be that the phone may be trying to check for available LTE connection more than it should or something along those lines? I don't know. Just some thoughts. I guess I'll see how this pans out today.

    This seems to be happening to a lot of people with the iPhone 5. I would hang in there and see if Apple has some type of six for this.

  • Canadajack Level 1 Level 1

    I did a full cycle charge on mine and its held up a lot better today... I haven't used it a ton today but i texted, surfed the web a bit and litened to some music. its been on for 12 hours now and i'm at 40 percent.


    Still hoping Apple patches their OS and it becomes more efficient

  • Delajosj Level 1 Level 1

    I have the 16 gig iphone 5 and the battery life is awful. It went from 100% to 45% in a out 3 hours. I ised it to text about 5 times.  I had email check for updates every 5 hours and wifi and bluetooth off.  I turned off lte just now and will let it charge overnight fo see if battery life is better.  My wifes 4s has double the battery life that my 3 dY old iphone 5.  :(

    Guys, Please provide critical feedback to Apple!

    They should know about this issue!

  • cytjoseph Level 1 Level 1

    I am also very dissatisified with the battery life of iPhone 5, the battery just drains so quickly. Claiming that they have done much to improve the battery life blah blah blah... APPLE did not make any improvement at all.

  • Delajosj Level 1 Level 1

    Thanks for the link I submitted the feedback on the poor battery. How sad waited for this iPhone five to come out & battery life is so poor!

  • Delajosj Level 1 Level 1

    I'm in the same boat as you on my iPhone five battery doesn't last 4hours and it gets down to 40%

  • Arkanok Level 1 Level 1

    I just submitted feedback to apple using that link. I hope this is just a software bug that can be fixed with a software update,I love the phone but don't want to use it to its fullest because it will just end up dying before I can charge it!


    Common apple, you're better than this.

  • jeffj4AU Level 1 Level 1

    When you first get a new iPhone, you need to run the battery down a few times and after a week or so, the battery life normally gets much better. I'm not being a SA, but most of the time these kinds of issues are user error.

  • DJKOR Level 1 Level 1

    Lithium-ion chemisty does not typically need to go though those types of cycles to "stabilise". If that was the case, every device of mine would have improved in battery life compared to when first used which is certainly not the case.


    Besides, my iPhone 5 has now been through 4 full charge cycles (as in down to 3% then up to 100%) and is showing no changes in its capacity. Also has had multiple partial charges gaining anywhere between 10-30% of charge without showing obvious signs of improvement.

    Try doing Settings > General > Reset > Reset All Settings. I had an overheating, battery-draining iPhone 5 yesterday, and the reset seems to have fixed that. Battery life was reasonable today, and the back of the phone was no longer hot.


    A restore would probably also work, but a reset takes much less time.


    It seems to be similar to the bug that hit many people in the iOS 4 -> 5 update last year.

  • DJKOR Level 1 Level 1

    Well, haven't hit the full end of the day, but have reached the end of the working day.


    Disabling LTE has made a rather large difference to my battery life. I would estimate it to be about 1.5 to 2 times better than when I had it enabled. Not exactly a conclusive or accurate test or anything, but just stating my own experience here.


    I guess the next step would be to turn it back on tomorrow and try and use it about the same as today to see if it goes back to how it was before or whether something else has changed.

  • Mad4Macs Level 1 Level 1

    Feel the same.  On day 1 the % abttery left semed to just dissapear while I was using it.  My 4 always seemed to stick at 100% for a while then go down at a reasonable rate this gos from 100% to 99% right out of the gate.  Did a video test this am - 2hrs of video takes 24% battery - should be 20% so maybe within spec.  Main culprit is anyhting using the radio - even WiFi surfing brings the % down as you watch over a period of minutes.

  • Arkanok Level 1 Level 1

    Alright so I tried something, I left my phone to charge to 100%, disabled LTE so that it was on 3G and WiFi only, then at 11:25 pm EST I pulled the power cord out and just left it on the desk overnight, completely untouched for the entire duration. At 7:45 am EST I checked the battery level, it had dropped to 90% in just over 8 hours. Then I checked the usage times in the settings, I was fairly surprised:


    Usage: 5 hours, 38 minutes

    Standby: 8 hours, 22 minutes


    Really? 5 hours and 38 minutes of usage time? Nothing happened to the phone overnight so I don't know where over 5 hours of usage came from, but my only conclusion is that there must be some processes that shouldn't but running, running. I mean, for more than half the time it was just sitting there, it seems to have been doing something all by itself.


    Does anybody know what's going on here? Is this something that could just be fixed with an update to make things a bit more efficient? I'm not very happy about this.
