Q: iPhone 5 battery life is way worse than iPhone 4

Hi I've noticed recently,that when my iPhone 5 battery drops below 50%.

My switches off ! Don't know if its software or a hardware issue ?

Your not alone!!

I had actuallly been coming to this conclusion as well. It seemed especially drastic when chatting in that FB app, and the FBchat app isn't much better--on top of its habit of crashing every 20 minutes. I'll try this out!

I have an iphone 5 and I cant seem to get it to last past 5 hrs usage.

Took it to Apple, they said this is normal. Turn all notifications off, location services, and do email every hour.

My question is then... why have a phone? if i can't have my email coming in? I could do this easily on a blackberry!!!!

My friends on the 4s have better battery life than I do.    Any suggestions? would any of you suggest going back to the 4s?

They're creative aren't they?  Turn this off, turn that off.  I've tried it all and cannot get more than 3-4 hrs usage.

Ive had my iphone5 for 8 months now and have never had it last longer than 6 hours.So for everyone concerened about poor battery life unfortunately this seems to be reality with this phone.  I had had it swapped twice by apple and it hasn't made any difference.

it just doesn't seem to change whether you have certain things turned off or on--if so then only minimal difference and not worth the effort.

Something strange did happen the other day though--I changed my language setting from English to British English and my battery capacity went from 81% to 86%.

I don't know why the battery decided to give me back 5%--I have tried to replicate again with no success.

It seems to me there is some hardware calibration battery issue with all iphone5's and perhaps the only hope for resolution is when ios7 is launched next month.

JDawg, I certainly hope that's the case with IOS 7 but I have yet to see a new IOS release improve battery consumption.

I too have had the iP5 since launch day and have had mixed results as far as battery life goes.  After following this thread and several others I've come to the basic conclusion that 6 hours is about the norm for most users.  Clearly the phone is capable of more as stated by Apple,( using VERY specfic condtions), but also by several tech publications in their own tests.  I think it's a situation of ever increasing hardware capibilty meeting the limitations current cellular technologies, I've noticed that alot of the complaints about extremely low battery life seem to be coming from Europe as well, so maybe there is a connection there?  Hard to say. 

I'm currently running iOS 7 beta 3 on my phone and I think there is a difference.  I still get some varied performance, but the over all results point to better battery life in general.  Overall my feeling is that there is a design flaw within  the hardware architecture that the engineers were unable to completely overcome in iOS 6, but hopefully will have solved for the general release of iOS 7

I have also found the battery life less than ideal! Added a second battery, Mophie Juice Pack.

It's weird that so many people have such a poor battery life.

Mine after 24 hours of ussage has 19% of battery left. (Running 3G only)

I bought my iPhone 5 from future shop with the extended waranty the iphone's battery life was terrible, so I took it back, they did a simple test, played a video off YouTube for 10min, in 10min my battery drained more than 15%, so they gave me a new phone, if the phone would only drain 10% or less it would have pass the test, in my opinion if the battery drains more than 10% in 10minutes apple should replace the phone, before you do this test its recommended to erase the data of the phone

Had the same problem and was seriously bummed.I was losing about 1% power every 2-3 minutes and the phone was losing half charge overnight (about 25% with airplane mode on). Last night, I ran the battery all the way down until the phone turned off, and then re-charged. I used charge indicator in BatteryDoctor to make sure that I was at a full 100%. Today the phone's working great. I've been using it all day and it's still at 63%.

One nice Philips App shows how we can manage the battery. It is called Philips BatterySense. Gives advice according to need what apps should be turned off at the battery condition of that time.

It's helping me get best out of my battery. I have got a 64 GB iPhone 5.

Congratulations. Apple suggest you do that once or month or so to recalibrate the accuracy of the battery readout. I assure you that the app did nothing to improve battery life.

12 hours standby and 5 hours usage 61% left on iphone5, with cellular data open, mainly used in txting. is this ok?
