    I had my iPhone 5 since it was released.  All of a sudden the battery life went down to a few hours per recharge.  I would charge it before I went to bed and when I got up the battery percentage was down to 3 or 4 percent left when I wasn't using it.

     

    After going through backing it up in iTunes and restoring it with no noticeable change in battery performance I started experimenting.  I turned off LTE and had a little bit of improvement.  Then i turned off cellular data all together and my battery life was back to normal.

     

    So I figured it may be one or more of my apps that were misbehaving on the data side.  I backed up my phone again using iTunes and iCloud.  Then set the iPhone5 back to factory defaults wiping out all data and apps (Settings -> General -> Reset -> Erase All Content and Settings).  I tested the phone like this for a about a day and the battery life was fine lasting all day.  I started adding my apps back on through the App Store app on the phone (App Store -> Updates -> Purchased -> Not on This iPhone).

     

    So far so good.  My phone battery has been lasting all day and I charge it at night.

     

    It has been working for about 3 weeks now since I did this.

     

    Just FYI in case anyone wants to try this out.

    Funny that despite the prevalence of this issue, no one at the Genius Bars seems to know much about it or have a real fix.  I was having the problem since about a week after I got the iphone 5 and it was happening intermittently, bad for  day or 2 and then OK for a week.  2nd trip to the Genius Bar and I reset the phone back to factory settings, recreated it as a new phone and manually re-added all the apps, music, etc.  (This process would be much easier if the iTunes app for organizing apps worked better.)  Anyhow, a week later, same problem.  I tried a bunch of "fixes" in the forums - deleting and re-adding calendars and email accounts, etc.  No help.  3rd trip in to the Genius Bar, I got a new phone.  WIth the totally naked, virginal phone, after I left the store, I added back my email accounts (gmail and icloud) and calendars.  WIthin minutes, the phone was getting hot and draining battery. Nothing else was on the phone, nothing else active, so it certainly suggests that syncing mail or calendars was the problem.  4th visit to the Genius Bar, we changed all the email accounts to fetch instead of push.  Actually, the only one that was previously set to push was iCloud.  I have them all fetching every 15 minutes and have not seen the problem since.  It's been just a week, but I am hopeful.

    My iphone 5 is having the same problem, the battery drains super fast....well compared to how it should be about 20%-30% an hour with minimal usage. Since the 3G communication is draining 10x more power than wifi.I am very disappointed and really make me sell my iphone.They can not handle it, let us leave that we can change the battery.I am om ios 6.1 beta 3. Same problem as 6.01. HORRIBLE BATERRY LIFE. (ONLY OVER 3G) Wifi is ok.

    The same thing was happening to me after several days of firing up my 5. It was like watching the fuel gauge of a large SUV while I watched my battery % drop by the minute. I did a bit of digging and found this solution that most of you should try. I myself restored from an old 3G iPhone. It appears to have worked for me.

    It's because it is irreversible once you upgrade the firmware.

     

    Wow, that is amazing.  Good job Apple for COMPLETELY covering up this major battery issue for so long, BRAVO!  Serious I haven't seen a single media outlet at all talk about it, they must be greasing some palms really well since it's been how many months now?!   I seriously can't believe Apple hasn't acknowledge ANYTHING on this, I'm so sick this BS!  Say SOMETHING, tell us your data shows we are all stupid and crazy, just SOMETHING!

     

    I am so digusted with this company, yeah I'll keep my stupid phone cause I can't return it and I'm not made of money to buy something else.

     

    Here is my latest usage!  You'll notice I'm at 1% and didn't even get FOUR hours of usage out of it, AWESOME!

    How did apple calculated 8 hours for surfing on 3G?

    Was the brightness on 0? Iphone turned off.?

    How did they tested it in gsmarena?

    Because every user uses their phone differently, but 3 hour surfing on 3 g is not normal.

    Is there some kind of test that every user can test their phone or

    is there an app which can test correctness of the battery or the phone.

    Got my new iPhone 5 this Sunday. I had the 3gs for three years and LOVED it. Only in the past 6 months did I notice the battery start to go down. However, after getting this phone I would say the battery life on the 3gs was still better. I find my battery to drop rapidly at times. I don't play games or watch videos. Last night scrolling through the screens and lightly looking at facebook it was dropping 1% every 30-45 seconds...then just stopped. I have LTE turned off, use wifi, turned off the majority of my GPS, and have my email sent to push every 30 minutes. That seemed to help a bit but not much.

     

    Here is what I find weird. THe first day i got it i charged to 100% it dropped a lot but i didn't think i would have to charge it over night. However, over night it dropped 15%. So last night I decided I wanted to do a little test with how I have my settings now so I didn't charge it over night and reset all of my statistics...in the process of resetting them...i found this, under call time: LIFETIME: 9 DAYS, 22 HOURS

     

    Can someone explain this to me? How is I have only had the phone since Sunday, December 1st...yet it says I have 9 days of call time usage?

    Hi friend,

     

    The life time information started to count when you made the last full battery recharge. I can understand you just have your mobile for around 5 days. But also your mobile came with a small percentage of battery, it was charged in the factory. That is the probably reason why your mobile had more than 9 days of battery lifetime.

     

    Hope it will be helpful,

    Actually, your statements are not accurate.

     

    First, when I received my phone, while I didn't check my lifetime usage as soon as I turned it on, I did check it after the first full usage and it was only mere hours. It matched my standard usage until I reset the stats.

     

    Second, I've had my phone for almost 2 months now and I do not have anything NEAR 9 days of battery lifetime usage and I use my phone alot. I am at 3 days and 12 hours and I received my phone 1 week after Verizon made it available.

     

    Either the battery was not reporting the usage correctly or something else went awry. While it's possible you could've had a phone that was refurbished, I am still inclined to think there is another problem because 9 days of usage is an insane amount of time on the phone and I'm not exactly sure that would even be possible from it's launch on most phones. (Remember usage time is not standyby time.)

    Here is a fix for battery drain.  If you did a full restore on data from your laptop or Icloud from the backup of another version/model of Iphone that is the problem.  You have to do a fresh build on a newer or different model of Iphone.  If you did a restore from a differnt verision/model of Iphone that is were the problem lies, it works and it is quick and convient, but that will unfortunately lead to battery drain problems.  Turn on and setup Icloud.  Save pictures to Icloud or Iphoto on computer, Make sure you know all email, apple ID and Icloud account info.  For good measure do a backup just in case.  Then You do a full reset on your Iphone.  Do Not Restore from a backup! Turn phone on enter your apple ID, ICloud, and mail accounts reload apps and your battery will be working great again. It is a few hours worth of time, but battery won't die prematurly anymore.  I had the same problem going from a 4 to a 4s thought that they would have it fixed for a 4s to a 5, but you have to do a fresh biuld.  It is not all that bad you get Photo's from ICloud or from your save on IPhoto on your computer, all your contacts from email accounts or ICloud, and many email accounts have notes backed up as well if not ICloud can have them.  You get your purchased music direct from ITunes and or your computer ITunes and or ICloud, and you get your purchased and free apps from the app store or Itunes on your computer.  Not an easy job, but definitely worth it.  After you get everything loaded do a backup to your ITunes from time to time for safety and you can do an easy restore back to the same model of Iphone, incase you have full loss on your new Iphone 5, God for bid, with good battery life.

    The above fix isn't working for a lot of people, including myself.

    Yeah - it doesn't apply to me.  I did a fresh install.

    The facts about this phone are this:

    The battery is terrible and there is obviously no fix for it.

    The screen could have been a little larger but I guess I had different options

    The cellular Internet is what really kills my battery, on wifi I could get 10  hours possibly but on cellular I would be lucky to get 3 or 4 hours tops.

    Sadly I have already come to the realization that this will be the last iPhone I purchase. To bad I signed a 2 year contract or I would have already gotten rid of this one. I guess that's all
