Why does my iphone become hot to the touch?

iPhone 4 will occasionally become hot to the touch. This seems to happen randomly, without any rhyme or reason, or warning.

Hello dhartz61,
When troubleshooting temperature, please refer to the following article:
iPhone, iPad, and iPod touch (4th generation): Keeping device within acceptable operating temperatures
http://support.apple.com/kb/HT2101
When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside.
By all means, if you believe the temperature is a concern, you can isolate the issue by restoring your iPhone as new:

Thanks,

Why does my iPhone 4GS bounce of the TV

Why does my iPhone 4S bounce of the TV (not flatscreen, old thick Philips) when I put the iPhone on top of it? It happens after some time, perhaps 20 minutes. The phone bounces of the TV and lands on the floor. The TV is off!

Hi,
That sounds like attention seeking behaviour.
Step over it and ignore the antics.
When it behaves in the fashion you expect it is OK to pick it up and follow the normal nurturing you use.
If you do respond to it you will soon find yourself planning a zip line from your upstairs bedroom to the kitchen, coupled with a refusal to get in your pocket when you are ready to leave the house.

Why does my iPhone 4 not have the panorama feature with the new iOS 6 ?

Why does my iPhone 4 not have the panorama feature with the new iOS 6 ? Can someone please explain this to me. I was already excited about it.

That was made available in iOS 5. To update, you may need to connect to iTunes

Why does my iPhone arbitrarily brighten, to the point of decreased resolution, despite my having turned off auto-brightness and setting the brightness to maximum?

Could be a hardware failure.
Restore the iPhone, first from a backup, then as new, and see if the issue persists. If it persists when you restore as new, then there's a hardware issue with your phone and you need to bring it to an Apple store to be evaluated.

My phone becomes hot to the touch

My phone becomes hot to the touch-front & back and usually complete battery drain ensues. Is this a fixable problem or do I need a whole new device?

Take it to the Apple store genius bar and have the techs test if for you...they can tell if it needs to be replaced.

Why does my iPhone 3G/iPod repeat the same song over? I can't get any playlists or albums to play...

Why does my iPhone 3G/iPod just play the same song over and over? I cannot figure out how to get it to shuffle or play through an album or playlist... It just started doing this randomly and it's very frustrating!

You have probably Repeat turned on. See the top of p. 77 of the User Guide.

IPhone become hot and the battery drop

Hi All,
My iPhone is having problem. My iPhone is 3Gs, 32 GB, OS 4.2
My problem is: the phone suddenly become hot and make the battery drop, and it's already happened for 1,5 weeks. It seems my iPhone is reading something (perhaps some application) but I don't know what.
Can someone help me?

There is some application that is stuck trying to send data. The most common app to have this problem is email, but first try a full reset (if you haven't already: Hold the HOME and SLEEP buttons until an Apple logo appears, ignoring "Slide to power off",
If this doesn't fix it next try the following:
Go into Settings/Mail,Contacts,Calendar. Tap each email account that uses PUSH and turn it off (turn off the ACCOUNT, not PUSH). Close Settings and open the email account; verify that the account does not appear. Then exit Mail to the Home screen and do a reset again.
Once the phone comes back on go into Settings and turn the email accounts back on. Fully charge the phone and test it again.
If you still have a problem you may have to restore the phone. Connect to iTunes and click the Restore button. If you have previously restored or updated and that did not fix it this time set up as a new phone.

Why does my iPhone (4S) and iPad (The New iPad) keep asking me for my Apple ID password after I created an iCloud account and merged my old Apple ID with a new one?

I got an iPad2 for Christmas and went to the Apple Store to have them transfer over my contacts from my iPhone4S to the iPad2. They said they had to do it over iCloud and help me set up an iCloud account. But I had an old Apple ID (one without an "@icloud.com" name or other email address attached to it). When they did that it basically screwed up my whole Apple ID account. Now, both my iPhone4S and iPad2 randomly prompt me to enter my Apple ID password for my old Apple ID!, which they said does not exist anymore. So confused...please advise.

The email you should NOT have published, is your iCloud, not Apple ID
You Apple ID is a valid email address
This is a user forum, not Apple customer service.
I gather the security question did not work.
If you have an email address, why not use that?
If this fails you have to contact support and schedule help.

Why when I use any chess app that can send PGN files to an e-mail, why does my iPhone can't send the PGN attachement file?

I downloaded the app "Chess score pad". It was supposed to send an email with a PGN attachement to me, but it didn't worked. it only sends the text but not the attachement. I can send other type of files like photos, audio and videos. Why can't I send PGN files? Help please!
I have already contacted the creator and we have already proved that the problem is with my iPhone only. What can I do? (The app works with other iPhones and iPads.)

Chrisj4203, thank you for your kind answer.
I have done a lot of restores to the Iphone, and resets also.
I;ve done holding both buttons as you sugested, but there is no signal appearing.
I am in Uruguay, South America and the original company is Movistar ( Telefonica) and the new sim card is from ANTEL ( the officail and biggest company in my country).
I don;t knoe what todo.
I have been trying for more than one mont.
I have gone several times to both companies. Aldo two times to Apple uruguay, and nobody can help me.

Why does my iPhone not charge with the wall charger?

i have recently purchased an iphone 4 (within the last month). it has charged via the wall charger at first but now, the wall charger does not work. it does charge by connecting the USB cable to my computer. is there any way i can get my wall charger working? or will i have to get a new one? thanks.

Try a different wall socket - if you haven't already and/or try this.... reset the iPad
Hold down on the sleep and home buttons at the same time for about 10 seconds until the Apple logo appears - ignore the red slider - let go of the buttons. then try again.
You could also try updating your software as I have no idea which version you are running on your iPad.

Why does my iPhone become so lag and slow after downloading iOS 8?

My iPhone 5S and iPad Mini Retina Display become so lag after after downloading iOS 8. When i open an app or press any button, it response very slow. For instance, opening a Facebook app take about 30s for it to load, answering a phone call take half a seconds to response. Not only that, my iPad keep restarting when I am FaceTime-ing about 3 minutes. This update has got me so frustrated! It is so unstable!

Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

Why does my Iphone 3 keep opening the ap store when I use Safari?

This just started happening. My phone keeps opening up the app store by its self. This happens when I am on a web site. I will then show I have 2 apps to update, but nothing needs updated. I have closed all open apps, cleared history and cookies and data in safari, and reset the phone. Nothing works. Can someone please help?

there should be a way to prevent such behaviour.
There is. You can go to Settings -> Safari -> Advanced and turn off JavaScript. That will break many websites though. Or, you can simply stop visiting the sites that are doing this, which would be my choice.
Alternately, if this is happening with every single site you visit, you may be having some problems with your network. As an example of the sort of thing I'm talking about, see:

Although the following page is written for Mac users, and thus some of its advice is not appropriate for the iPhone, you can still find some good information on such problems here:
