    Posting somewhat acceptable battery results: I've got 11 hours of standby with 80% left and 1.5 hrs of use. Running 6.0.1, Location services ON for all of the apps I use, iCloud ON, Push every 15 minutes. I'm just happy my iPhone isn't draining battery on standby like some report!

    Hmm, LTE? Thats actually pretty good. Im assuming you meant fetch every 15 minutes.

     

    Forgot to say what I run. iCloud on in manual for: Reminders, contacts and find my iphone.

    3 exchange accounts on push.

    Location services on for: Maps, Reminders, Find my iphone, Mobile network search and setting time zone.

    No offense taken whatsoever.   The LTE chip, PLUS the circuitry to manage the dual antenna system that the addition of LTE required, IMO is the culprit.   It appears that this system is somewhat diabled when connected to wifi, which cuts down on the heavy battery drain.   I'm of the opinion that this is not a simple firmware fix, as anything they do to improve battery drain will also cause performance problems for both calls and data.

     

    We can agree to disagree, but only the release of 6.1 will tell who's right.   I'm a believer that there is no acceptable solution coming.   Hopefully, I'm wrong.   And, hopefully 6.1 will be released sooner, rather than later.

    Please dont take offence when I say this but have you read a few of the posts above, mine included. The iPhone 5 MUST have the capacity. While on WiFi it is on par if not better than the 4/4S. Once it is switched back to 3G it drains like theres no tomorrow. This doesnt make sense. If it were poor on WiFi, I would understand but I am able to get 12 hours on WiFi, browsing and gaming.

    That is better situation then mine. Even on wifi conection with cellular on, it gives me max 5hrs. 4hrs will be lucky on 3G entirely.

    Ah, I see where youre coming from but surely it shouldnt be disabled as iOS 6 relies on mobile data if there is a problem with WiFi.

     

    It probably activates when no data is being received from WiFi TBH.

    I've noticed much better life after switching 3g and cellular data off while on wifi (no LTE here in NZ). Now, here's a thought. With all of the above switched on, how may people think it could be a switch management issue were' seeing on the higher drain devices between the WiFi and the cellular. What I'm meaning is, there is a difference between a strong WiFi signal and a stable WiFi signal. If you're experiencing micro-outages of your wireless and it keeps switching back and forth between it and your cellular connection, that would definitely shorten battery life. I would guess that was one of themain reasons people were seeing huge cellular data bills as well in the US when they say they were on wireless. What if that bug isn't completely fixed. Just a random thought....

     

    As for the hardware versus software debate, I believe a bigger battery would have been better than a slimmer phone but that is a non-issue now as we have what we have. I think they are being a bit too agressive with the 3G/LTE side of the phone as far as trying to amplify the signals. ****, it could be the dual cell (MIMO) which is causing the biggest issue. Remember, our iPhone 4 and 4S phones talked to one tower at a time. These will happily talk to more than one and it could be the management of that which is killing our batteries. This new feature could be our smoking gun as far as drain. I fully believe this phone will do 8 hours on 3G, as long as it is only talking to one tower. I may just test this by getting a sim from a provider here which isn't doing DC-HSDPA yet and see if I'm right. Maybe they should add a setting to turn this feature off to see if that truly helps things....

    Agreed on everything you state Cliff.   I've also noticed that when I wake my phone from standby, the display shows as 3G/4G or LTE, but immediately switches to wifi when present.   Makes me wonder exactly what state the phone is in when in standby mode, even with wifi present?

    BATTERY LIFE ABSOLUTELY ***** ON THE IPHONE 5. I've owned every iphone except the 4s and i have absolutely the worst battery life of all time. I literally get about 4 hours of usage out of it all the time. I got a new one from the apple store to replace the faulty one and im still having the same issues. This is absolutely brutal. I think there must be something wrong with iCloud backup that's causing this battery life draining issues. My phone doesn't even last me half a day and my iphone 4 used to last me 2 days no problem. I tried doing a restore to my phone, no fix, then i got a new iphone from the apple store and restored my backup again and it continued to be poor so i DFU my phone and setup as a new iphone and started everything all over again, lost my game saves, messages and settings (such a pain) and my battery life is just as bad as it's always been. Clearly there is some sort of software bug with ios 6. I figured that ios 6.01 would fix this issue since it fixed all the bugs so clearly apple must not know of this issue. I wish apple could just acknowledge the issue and address there will be a fix at some point. They should come out with ios 6.02 to address it, i don't want to wait until ios 6.1. This is completely unacceptable. Apple needs to know that this *****!!

    and all this stupid ideas of turning off location services, turning off wifi, LTE, turning off GPS, bluetooth and fetch emails less often is the stupidest idea i have ever heard. Doing that is pointless. I want to USE my phone. Not have all these awesome features and need to turn them off to get the desired battery life i want. Those things are to extend your battery life, not to meet the specified battery promises apple gives us. And i know that the iphone 5 battery life has to be great because absoultey every review i have read on the iphone 5 has claimed that the battery life seems to be better than the 4S and that they were very impressed with that. I want a phone like that and then my phone will be perfect. Everything else on it awesome except the STUPID BATTERY LIFE!!!!!!!!!!!!!!!

    Went to a resturant last night with over 50% battery was there for max 2 hrs and didnt use the phone once it was in my pocket the whole time. As I leave I go to make an important phone call but guess what? Phones DEAD!

     

    I never had this problem with my iphone 4 (unless I used GPS for a long period of course) and I never had to worry about not forgeting to leave the house with a charger in my pocket. (Because my phone lasted the whole day!)

     

    Trust me besides the online reviews NOT one person I asked about battery life on the iP5 said it was good or better than their 4/4S.

     

    The only thing I can now hope for now is that the new Mophie Juice packs dont make the phone look like **** and ***** that I cant just have the phone last all day like we all need the way it was intended.

    I recently bought the new iPad 4th Gen wifi only. Not cellular because I reasoned I never use the data on my iPhone 5 and can connect that to my iPad and thus no need to get another SIM card and data account.  This weekend for the first time at friends I connected up my iPad to iPhone and used as hotspot over wifi on 4G LTE. I had about 30% iPhone battery life. After about 10minutes and hardly even using the Internet on my iPad the battery on my iPhone 5 was almost gone to 0%.  Literally I good see the percent numbers dropping, 25, 24, 23..... On my iPhone 5.  If this is going to be the best it gets it is not acceptable. I now wish I ad bought the cellular version iPad. Will they give me a refund? I am going to go to Apple store in the next few days and see what they say..

    There's one review of a testbuy magazine here in Belgium and they actually gave the iPhone 5 a so so review. The two main reasons being the maps app and the bad battery life.

     

    They did a test were they download packages over 3G. The samsung galaxy S3 lasted over five hours, the iPhone 4S only 3,5 hours and the iPhone 5, much to their disgust, was dead in three hours.

     

    So it's not just us users who are experiencing these issues.

     

    All we can do is wait for 6.1 to be released and pray for a miracle

    It would be nice to get the phone we paid for. If we don't, it's up to us to learn something from it.

    ** Breaking News**

     

    This just in, Apple has come up with a fix for the battery drain issue. Apple has approved design for the 1st "Apple Certified" battery CASE for the Iphone 5.

     

    Thats Apple's fix for u guys. Go out and buy u a case to extend ur battery life. Reports say the case will provide 3000 mhr of extra battery power.

     

    I WISH THE **** I WLD.

     

    ** Partial Solution **

    1. Update all APPS to be 6.0/Iphone 5 optimized. Meaning, get rid of all apps that haven't been updated since the release of the Iphone 5.

     

    2. Update mail accounts. There is something going on with email sync. Go thur each folder in each account & eliminate old and no longer needed mail, yep even in the junk mail folder. U might want 2 do this from a desktop r ur laptop. Delete mail account from phone, reset all network settings, then re-add each account.

     

    3. Stop MONITORING YOUR battery every 3min to see "exactly" how fast its draining. Common sense shld tell u that doing this is wasting unnecessary power by constantly pulling the phone out of lock mode, if u even have auto lock set. "My phone drains 1% every 2min whilst browsing the web" and what not. Ppl spend more time watching the battery than doing anything else with the phone..

     

    ** DUECES **

    I was wondering why this isn't a bigger public issue in the media/blogs... I guess these days there are alot more places for people to vent their fustration so its more spread out than concentrated. Just do a search for "iphone 5 battery" in twitter for endless tweets about people not happy with iphone 5 battery life. https://twitter.com/search?q=iphone%205%20battery&src=typd or just click there... I throughly enjoy the phone otherwise but there are other up and comers that i might have to think twice come next "upgrade"
