    I'm running an iPhone 5 with stock iOS 7.1.1

    In the past 2 weeks, I've noticed that my iPhone gets unusually warm on occasion and the battery drains more quickly than normal. A reset of the phone seems to make the issue go away for a few days.

    I disabled background refresh, and I've always had location services disabled.

    Is there any way to see if a particular app is going haywire and driving up CPU use? I suspect that an app updated at some point and has bugs which are causing this.

    My 5S would do the same thing sometimes. Never understood why. Was just something that would happen from time to time.

    Things tend to get heated when there is electricity running through it. I would say that you should go to an apple store and see wazzup

    My iPhone is back to its normal fairly cool state. I'm not sure why, but I did have a few apps update, so maybe a bug got fixed.

    I'm out if warranty at this point so I sure hope nothing is wrong!

    mine does this. Nothing is wrong it's just under heavy load. It usually happens when i'm charging my phone and on 3g browsing.

    A mile high
    Needs antifreeze or the processor will overheat.

    Heat is caused by increased battery drain. Common causes are GPS usage, high backlight usage and high CPU usage.

    Look at your app usage to see if any is triggering the above. Seeing as it's heading into summer and brighter days, this will push the brightness to max when you use your phone outside so check the brightness.

    I dont use gps , locations are off, background light is on auto, most of time 20-30 percent, the last thing is cpu usage... But i dont use it insane with games or stuff , its normal usage with normal apps , fb, safari, instagram .apps like that..

    My i5 gets hot whilst using 3G on a call, or especially web browsing (on 3G). Sometimes very hot. The rest of the time the temp is perfectly normal.

    That doesn't sound right. It's expected to see a temp increase when using the phone continuously like navigation software, but very hot?..

    I can use my 5s for an hour web browsing, and the temp doesn't rise any, wifi, 3G or lte.

    Mine burns sometimes when I play certain games for too long, I just don't really pay too much attention to it.

    That happened to me until I had the battery replaced. Not sure if the two are correlated. :confused:
