I've posted my story much earlier. It disturbs me very much that Apple continues to take simplistic measures on their side, or to just have us reset our phones and start over (unacceptable). I was at dinner with my wife and some of the other execs of a major retailer that predominantly uses the iPhone, and all of them were experiencing terrible battery life, even with Mophies which everyone had. They are looking for alternative phones. I was able to solve my problem by moving to periodic "fetch" for my email accounts. Businesses can't do that, as their needs are immediate. It also appears that doesn't sove the power drain issue for many of those posting here. There appear to me numerous "causes" of the drain, but I suspect we are often hailing phantom fixes to a problem caused by random interaction across apps, mail accounts, and phone technology. I also have the Galaxy 4 which has much longer battery life.
I just got the iPhone 5 this past Saturday, Aug 10th, 2013.
PROBLEM STATEMENT: Out of the box it has TERRIBLE battery life.
SOLUTION: I have disabled EVERYTHING in the settings, I do not use it to talk, text, or email, and I uninstalled EVERY app. Then I put it on Airplane mode and flipped Do Not Disturb to 'On'.
SOLVED: The phone's battery has lasted all day so far!!!!! Solved, thanks everyone! This phone is amazing, I'm using it to weight down a stack of papers on my desk so the fan doesn't ruffle it, previously my stapler served this role. +10 Apple ingenuity!!!
My 60 days old iphone5 was giving good back up until one day (bout 20 days after I bought) it started draining like an open tap. It was hardly lasting for 12 hours. I had gone thru the online discussion forums and had reset the phone more than once without erasing the data, but it did not improve the situation. Then one evening I was carrying my iphone when I went cycling (which I normally don't do) and once back home as usual I put the phone on charge for the second shift of the day. By around midnight the battery was charged to 100%, I unplugged the phone and went to bed. As usual next day morning I picked my phone to put it on charge expecting the battery to be down by at least 50%. But surprise, the battey was still at 100% and it lasted for 2 days. I had stopped connecting the phone to the net long back in an effort to save battery life.
While I am not sure what did the trick, looking back I think the battery started draining after I had switched on the Nike+iPod application one day. Though the application was switched off shortly after i detected the battery drain, I think the reclaiberation happened only when I took the phone on my cycling trip. I know it doesn't sound convincing but try it if you have tried all other options. My phone is working as good as when it was new, so I thought I will share my thoughts with others no matter how silly it looks since I know the pain I went thru.
I'm throwing my hat in the ring as another who has done everything suggested in this thread and to no avail. I'm a developer and this is absolutely hands down a low level OS issue. For me, it started when I upgrade to 6.1.x. I have a partner who bought a brand new 6.1 phone. Drains within hours with no use. He has two friends whose phones drain within 2+ hours. And so on. Back to me, I'm on my third phone in a month, so it's not hardware. This is new behavior for the phone—and sudden. The first phone I owned was fine for the first 7 months. This is the 6.1.x upgrade. There's a bug. Apple may deny it or not but that's what's going on. (Of course, handicapping the phone until it's no more than a paperweight solves the problem but as someone noted, obviously what's the point.) This is not acceptable for a $500 piece of merchandise that I also pay an additional $100+ per month to use. I tend to agree Apple is not owning up to this. Each visit to the "Genius" Bar seems to result in yet another "play dumb" moment and the all-too-easy "oh, here's another phone" response.
As an engineering student, I have repaired over 500 iDevices in the past 10 months. (It started with friends and they were happy so they sent their friends etc.).
The iPhone 4S has a battery capacity of 1420 mAh. The iPhone 5 has 1440 mAh. And yet it has a CPU that's twice as fast and a larger screen! So no wonder this battery life is miserable...
I personally hate iPhone 5. Fragile aluminum housing, expensive and fragile screen, unreliable power button, terrible battery, bad reception etc. Some people come to me asking to fix their old iPhone 4/4S because they aren't happy with their iPhone 5...
Guys, I wish this could help. I used to have the same problem with my iPhone 5's battery draining very fast. It took me almost a week to figure out why it's acting like this. (I solved it accidentally)
All I did was just to remove the Nano SIM and compare/see the battery drain's difference between inserting it and not.
From there, I somehow blame the SIM's positioning or placement for the battery drain.
So, what I did to get it back to normal was to put back the SIM and be sure it is clean (Not Dampen or Wet) and properly positioned and inserted.
And that's how I think I fixed my Iphone 5. I really hope this could Help.
Thought I would post on here again after having another look at my battery drain issues.
This was all done today
My phone came off charge at 7.30am and by 1:10pm according to this I had used it for 2hrs 7mins, which was not the case. I had only used my phone once to send a text message (about 2mins use) after that it had been in my pocket until this picture was taken.
20% battery drain for not even using is not right.
App's were all apparently asleep
The second shot was taken exactly 2 hrs after and again I had not even looked at or used my phone but according to this I again had been using it for 1hr 5mins
Again 22% battery drain does not seem right if you are not using the phone
Again all App's were supposed to be asleep
On this screen I had shut down all apps that were running and according to Apple asleep so not using any power and the phone was not used or looked at but usage had been only 4mins
This time though battery use was only 1% which is about right.
So my conclusion and only viable solution to the battery drain is to close all app's because I think there is a bug that is allowing them to run even though they are only supposed to use little power, if any?
I may submit this to Apple and ask them the question. Although they should be looking at this forums.
I had posted about the FB app being the issue and to some extent that does play a part but for the first 2 screen shots FB was not running in the background asleep, so I know it is not that. So I would hate to think if I had left that running what my battery % would have been.
I have an Iphone 5 and i can say with conviction that Iphone 5 has a great battery life.You just need to know how to optimise it.For everybody's information I am an Electronics Engineering student and i do know a lot about batteries including Lithium.Here is what you should do:
1)The single most major battery drain happens due to display.
Fix: Hence as far as possible keep the brightness of the screen around 65%.Only in sunlight do you need the brightness to be 100%. Try and keep the auto-brightness off because it constantly checks the light sensor and adjusts the brightness.Keeping the brightness to 65% will increase your battery life by around 15%.Another thing is that you should avoid unnecessarilt turning on the display.Unnecessarily waking up the phone will consume even more battery in some cases than the display being on for say a minute continuously.
2)Location services optimisation:
Fix: As a lot of others have pointed out,Location services is another major battery drain.Now it is also true that you need the service to be on for 'Find my Iphone app'.Hence what you should do is keep location services ON and allow only certain apps like 'Find my iphone' to use location services.Turn location services off for all other services.you really don't Facebook and Twitter to know your Location.All these services cause the phone to constantly send the location data which in turn reduces the battery life.Optimisation of location services will enhance battery life by atleast 20%.Also turn unnecessary system services like compass calibration and location based iAds off.They consume a lot of battery.
3)Turn off Wi-Fi unless you are in a place with strong Wi-Fi connectivity:
Fix: Now what we need to understand here is that Wi-fi is a double edged sword.If you are at a place like say your residence and you have a strong wireless connectivity it is advisable to keep Wi-fi 'ON'.This will save a lot of battery and give you faster connectivity thus causing the screen to be on for lesser time (because you will be able to access content faster).But if you are in a place with a weak Wi-fi or you are moving about in an area without Wi-fi then you should turn wi-fi 'OFF'.When in a weak wi-fi area,your phone will unnecessarily use more power to get a stronger connectivity which is not possible.Also if you are in an area without Wi-fi then the service should be turned off because your phone will unnecessarily keep running the service lest it should detect an active wi-fi.Wi-fi optimisation should increase your battery life by at least 10-15%.
4) When in a strong 3G/LTE coverage area switch to 3G/LTE else disable it:
Fix: The expalnation is same as that of point number 3.Following the above suggestion will enhance battery life by 10%
5)Unless necessary,disable Push email.
6)Disable raise to speak feature in Siri.
7)Last but not the least,follow a regular charging cycle schedule and 'good' charging practices:
Fix: However far fetched it might sound the battery is analogous to a memory element as in if you do not charge it to its fullest capacity at least twice or thrice a month the battery degrades.The battery can thus thought to be a device which can in layman's terms be said to 'remember' what its maximum capacity is.If it 'forgets' its maximum capacity you will naturally be losing its full potential.Even apple has said on its website that the battery should be kept in regular use with regular charging.Similarly the battery should not be allowed to drain completely.As far as possible never allow your phone to power off due to low battery.This will definitely degrade the battery!
Another habit that people have is that they immediately disconnect the phone once it is charged to 100%.This is a bad practice.When your battery is charged fully allow it to charge for at least another 25 minutes.This is what is called 'trickle' charging in technical terms.Trickle charging is absolutely essential to enhance the battery of your Iphone or for that matter any electronic device.
Lastly never ever overcharge your battery.Disconnect your phone once fully charged after 30 minutes and before 90 minutes.overcharging causes the battery to heat up and Lithium batteries are not very heat resistant and their performance degrades exponentially once they heat up.
Following the above practices will enhance your battery life by atleast 25%.
If the above 7 steps are followed,I guarantee that your phone will last a moderate usage of 8-10 hours and a heavy usage of 6 hours.
I hope this helps.
This issue is deplorable. Please take a moment and read the above link. I found this after 3 hours on the phone with AT&T and 3 hours with Apple. Everyone was quite polite and civilized but I know if I can find this in a google search these people can as well. If neither AT&T or Apple will listen or make a change it is time to call for a class action.
PLEASE READ FIX!!!
Majority of iPhone users use the application 'Facebook', this is the main problem, my phone lasts 5hours if I'm lucky with Facebook installed, so I deleted facebook and my phone is now lasting atleast 20hours+, Also turn locations services of for the apps which arnt needed.
If you use Facebook often don't worry, just type it in sarfari and add bookmark to home screen, it's a lot better and battery lasts a lot longer.
Let me know if it works for you to.
So it's not apples fault it's facebook application, it needs sorting.
But it makes no sense that shutting down/removing Facebook fix the issue, because ALL apps (maybe beside Apple's own app, I'm not sure but...) can't run in background more than 10min. After that the app is in sleep mode and can't use any ressources and can't access any networks. Unless you're always on Facebook all the time and always playing with the app!
I got news for you people who don't think this is a problem because its not happening to your phones, it just happened to me and it is very real. I've had an iPhone5 for almost a year now and have never had any battery problems. The phone always lasted the whole day and then some even with heavy usage and a million apps running until I plugged it in at night.
Now all of a sudden, as of yesterday, my phone does not hold a charge for more than a couple of hours, even with all apps off and in standby. No apps were installed, nothing was changed. One minute it was working as always, the next it's draining so fast I can literally watch the percentages fall. The only things done to the phone over this time period where this behavior began was plugging it into the charger in my truck numerous times throughout the day, using an Apple made lightning cable.
So your solutions of 'disable practically every useful function on your phone and viola, you can get maybe a day of battery life' are about as useful a suggestion as making phonecalls with a rock is. Your comments of "it's not Apple, it's you" are likewise not helpful. This is obviously a bug, either hardware or software, with a very tricky reproduction case that has yet to be figured out.
You obviously haven't read the 91 pages of the thread you posted to, because most of the posts agree with you, and many of them tell you how to fix it (pretty simple most of the time). So either read, or start your own thread with a technical question rather than a screed and you will learn what to do about it.
I created a thread on this topic for those who feel the same and welcome anyone who can offer a link from a valid source showing how to fix the problem in one step that works for everyone. I need to add to my thread that when Apple upgraded my phone to 6.1.4 during a full reset it did stop the immense and premature data drain but not the battery drain. I was never told by the Apple tech that my phone was upgraded to 6.1.4. I didn't know the upgrade existed. My research shows it wasn't intended to fix a data spike or a battery drain and it was offered to me in the same fashion as all previous updates.. in a message. I was aware something more than a reset had occured as something was different in his reset instructions but when I requested he repeat them he only repeated typical reset instructions. I later discovered I was updated which he never mentioned he had done during the reset. If you search 6.1.4 in the forums some refer to it as a patch but a patch for what?

That is impossible, because the "problem" isn't a problem, it is a symptom that can have dozens of totally different causes.
Well, actually there is a fix that is gauranteed to work. Restore the phone as New, and do not restore your backup. This catches all of the possible causes.

If you restore an iPhone it will ALWAYS install the latest version. The 6.1.4 update was to fix a security vulnurability in the iPhone 5. It is for the iPhone 5 only; all other models fro 3GS and later are still on 6.1.3.
And one common solution to rapid battery drain is to Restore iOS.
