my iphone 5 is perfectly fine on 6.1.3... try a hard reset (hold lock button and home button till your phone shuts off)
Me too, only facebook messaging, whatsapp-ing and facebook browsing may cause my phone back to heat up. Browsing through 3G
I seem to remember a similar issue way back on an earlier IOS release. Also battery died quickly - maybe a search of prior IOS forums might help.
OP: There's not enough information to guess whether it's normal or not. It depends on what you're doing. An app that causes high CPU utilization will generate heat and consume the battery. This can be normal or it can be a problem (jb, rogue app, pink hearts/yellow moons/orange stars/green clovers). A recent example that doesn't apply to you was an ActiveSync loop that caused the device to endlessly sync with Exchange with the symptoms above. You can download one of many system utilities and see what's putting a load on your device during one of the times it heats up.
ive noticed this too, along with excessive battery drain. when browsing or using FB, the back of the phone definitely gets alot warmer than it used to on 6.1.2 and also drains 1% ever 2-3 mins when being used.
i am having the same issues...6.1.2 killed my battery now 6.1.3 still drains the battery and gets very hot like everyone in this thread has stated. ESP FB browsing...no this is not normal to drain 1% every 2-3 mins.. hope they send out a fix soon even with a mophie JPA i cant survive on the weekends with no battery.
Same here. Hot phone and crappy battery. Dont think it relates to LTE. Turning LTE off didnt make a difference for me.
I noticed this for the first time on Sunday when I was using the TomTom app in my car and had the phone on charge. It was extremely hot
i already took mine into the apple store and of course they asked me all the usual questions..restore as new, hard reset crap...im like yes i know all about this and still nothing..so they do the battery test and say there is nothing wrong with it..told them ever since the update it has done this and yes i wiped it clean and restored...same result...so i left the store...hoping they would come out with an update soon.. well last night i pick the phone up it drains 14% in 11mins and hot as hell.. R U F N kidding me ! i actually took snap shots of each min to show them how fast its draining. made another appt for this sat...they will replace it this time, this is unacceptable.
had them replace my phone on saturday morning.. again they tested the battery and said it was fine but i showed them the screen shots of it draining every minute. told them it was running very hot also while it was draining.. the replacement phone is great... right now at 3hours use 19hrs stndby with 60% left. def was something on the phone making it work harder in the background. thanks apple for taking care of it for me..
I'm not familiar with those apps but you can try deleting and reinstalling them. Is there a chance they aren't able to reach the server and are continually trying? You can also try a reset to see if that alone is enough.
Any suggestions for a good CPU monitor app so that I can attempt to diagnose this problem? I thought these were jailbreak stuff but is any good one available for non-jailbroken devices?
The more you use it, the hotter it gets. Intensive apps will heat it up quicker but all apps will heat it up.
Not necessarily--for example, over a period of half an hour if not even about an hour, I can browse different sites and check/use Facebook, Messages, and Mail in between, and the phone wouldn't really get hot or hotter over time.
Do you run it on 3G? Mine heats up when I do and playing large games gets that CPU hot and you can get knocked off wifi. I'd follow Pnutts advice, Sean006, because he knows what the hell he's talking about. Apple hasn't stepped forward and answered these problems outright, except for the maps which are still screwed up.
Hot iPhone 5 I'm on 6.1.3 and had this happen for the first time today. I received the "too hot" iOS error message. I was using Apple Maps on LTE. Weird.
Was the phone in the sun? It has to get very hot to receive that message. Thats a safety message that turns off tge phone to prevent damaging it. A GPS app will be quite battery intense however it shouldn't cause the device to overheat especially not the native app.
Given how often I do this at different times and places, sometimes I'm on WiFi while doing it, sometimes I'm on LTE, and sometimes on 3G--pretty much the same experience in all of the cases (the battery usage can vary in those situations, but usually the phone doesn't heat up with that kind of usage). Certainly with other kinds of usage like intensive gaming or something else the phone can and has gotten hot.
