    I'm finding my batt life is improving each day I leave my settings alone and let the phone settle as per jamiesons posts earlier

    Ended up with around 6 hours 50 mins usage

    Should I be returning this phone? I upgraded from the original Droid whose battery had been dying with data constantly on and it had better battery life than this.

    Handsfull is completely right. Wifi is no problem. It lasts for hours on wifi. If you're gonna post your screen caps here, use your phone 3G/4G/Lte and THEN let us know what you got. Showing a screencap of wifi usage isn't really showing us anything. My battery is dying one percent every 8 minutes on wifi right now. Every 2 mins on LTE and 4G... Use your phone in only cellular for one cycle and see how you do! Cheers

    If you have some time to spare.. I'd wait to see if something is released that fixes this... If you're at your cut off point then yea, I'd return it.

    Hi Guy!

    1/ The first thing i would like to say LTE ( not sure for 100%, but 85%) cause IP5's battery drain quick.

    2/ I rememered my first IP5 battery drained super dumper quick after Its battery is 100%. I turned powered OFF and left it overnight ( battery is 100%). On the next morning, it drained 30%. Later, I turned it to get  new one.

    3/ One my second IP5 , I did primary test battery that I used all of 75% when i got new replacement ones to 1%. Then, I plugged  until 100%. Again, turn OFF power ( 100% ), left it overnight.The result was 100%.

    4/ Note: this is the primary test on IP5's battery when you got the new ones. This test indicate how battery can be hold overnight ( 8 hours), For me, it's battery can hold 100%. This mean your battery is seemed good so far

    5/ Then, I used it untill battery was 75% ( or 85% or whatever you want). Again, Turn OFF POWER  ( it took about 8 hrs or less ). For this result was that is 75%. This shows that battery can hold when power was OFF.

    6/  Do not stop testing your battery, even your phone's battery can hold 100% as same as before.

    I have tested my IP5's battery for 2 weeks (14 days) after.  The result that battery was better.

    7/  On the day of 17, My result was Usage: 5h ++, standby : 1 day 5 hrs.  with 2% of battery life

    8/  After 3 weeks, right now, my result is Usage: 3 hrs 43 min and Standby: 1 day 13 hr. With 38% of battery.

    9/ you need write record on the paper when you take battery test. For me, I wrote it in order like Usage, standby, Times ( time is on the clock ). You will see  interesting number on Usage and Standby.

    I'm on my 2nd iPhone 5 now. My first one got an average of 4.5 hours of moderate usage on 3G/LTE. I restored, reset everything, and did all of the tricks but it was to no avail. My second one seems to be doing a bit better, but not by much. Like many others here, my phone lasts forever on wifi, which leads me to believe that this is not a hardware issue. But I'm still only averaging about 6 hours of moderate usage on 3G/LTE. I went for a 45 minute jog last night using the Nike+GPS app and it drained over 20% in that time. That doesn't seem so bad, but considering the same run using the same app on my iPhone 4 only drained about 8-10% of the battery, it is very clear that there is a problem.

     

    My 2 year old iPhone 4 still gets better battery life than my iPhone 5. I used it with the same carrier on the same network in the same region, and the iPhone 5 performance is undoubtedly worse for me. Really hope this can be addressed in an iOS update, and soon!

    Also just to mention I used no wifi on above stats only 3G with everything switched on apart from wifi and Bluetooth off.

    True. I'll try running again tonight or tomorrow with LTE off. But I have tried turning off LTE and only using 3G when I don't have access to wifi and I'm just out and about town, and my battery drain is still much faster than my iPhone 4. Just like everyone here, 1% every two minutes or so. I do believe that LTE is the real killer, but there is also a problem with 3G.

     

    Overall, I love what this phone can do. I love the way it looks and feels, and it is lightning fast. But as of right now I can honestly say I regret getting it. I'm not livid and I'm close to just accepting the fact that I'll need to buy a couple extra chargers and have one a work, but it is certainly not ideal. In fact, it's pretty ridiculous.

    fsuman110,

     

    You cannot compare the i5 to an i4.   They have nearly the same battery, but the i5 is much more power hungry (processor and LTE chip).   For those of us who had a 4s, there is little difference between the two when it comes to battery performance.   I can't really tell any difference after a month with the i5.

     

    For those of you who are seeing terrible battery life (1% drop every minute or two), I would suggest that SOMETHING in your configuration is not playing well with some poorly designed coding in iOS6.   Hopefully, 6.01 will address that.   Until a new release is available to us, you really have but three choices:

     

    1. Keep a charger with you.

    2. Turn off as many features as possible.

    3. Return the phone.

    I've been doing a ton of testing on my iPhone 5's battery. After muliple restores, replacments, and talking to several Apple engineers, I can only conclude that we will have to be patient and wait for a software update that addresses the issue. My iPad 3, iPhone 5, iPhone 4S, and iPhone 4 are all heavily affected and get a few hours on standby max. All have been restored without a backup and the iPhone 5 has been replaced 4 times (there is no need to replace the other devices as I know they worked fine before the iOS 6 upgrade so it's definitely not a hardware issue for them). The strange thing is that a restore or a replacement does fix the battery life issue until I charge the device again. I swapped my iPhone 5 out yesterday for a replacement (it was at 80% at the store) and 5.5 hours later after exessive use I'm at 55%. Of course, I thought the battery issue was fixed and plugged my phone in overnight. Got up in the morning and after just 2 hours of the phone sitting in my pocket it was at 70%. Did a clean restore and the battery life was fixed again...until I plugged it in. Don't know why it is doing this. I suspect the iPhone 5 still thinks it is plugged in when it is actually not thus it uses more power than it is suppose to. Anyways, we just need to be patient for a software patch from Apple.

    I don't see any mention of the battery life issue being addressed by this update.  That's not too encouraging for those having issues.

    Maybe they just aren't going to say it but the fix is there? Did they ever admit to it? I dont know but an update definitely is needed regardless lol

    Would be an absolute joke if this update doesn't address the battery problems. Come on, Apple.
