iPhone 4 heat and battery issues

My iPhone 4 was running very very hot today, and randomly turned off and has not been able to turn back on. Pretty sure I was above 40% battery, I have a feeling it's an app issue as has been stated, seen a lot of these posts lately, have a feeling its the LiveProfile app running a lot of data.

Same issue just like everyone stated after plug in USB into my iTunes and updated the OS, very regret of what I've done. Now my iPhone is toasty and I can't even talk to anyone for more than 5 minutes...... and the battery drains out 20% even it's in standby mode with no program running and the phone runs out battery in 2-3 hours too.

Getting quite sick of iTunes updates now, i'm nearly afraid to plug my phone into th PC at this stage!! Currently waiting on it to restore now because of latest "update". Just hoping i wont have the heat/battery issues people seem to be having. urg, urg, urg.......

Well I don't feel want to turn on my iPhone at all at this stage, it's just soooo boiling and I don't feel good at all. Phoned Vodafone they believe it's faulty, might get it replaced. But man, what's with the phones these days, they're so faulty. and mine is only one month old! You just gotta love the old Nokia 3310 that you wanted it to be broken and it lasted years perhaps.

This is an issue with 4.3 and 4.3.1. The same thing is happening to me. I wish I hadn't updated. I'm simply posting so that Apple realizes that this is affecting many, many people and will fix it in 4.3.2.

Honestly, my GSM iPhone 4 did not face such problems, no over-heating or battery drainage. I was on 4.2.1 and went to 4.3.1 instead. My battery performs well and no quick drains. I did a full charge in the morning at 100% and in the night, I still have 40% left. Surfed the net today with Atomic browser, facebook app, instagram, emails and lots of whatsapp. My Ping and findmymobile are On.

I do think (or i'm wrong) are that such issues occur due to iPhones from 4.3 to 4.3.1?

whadda y'all think?

I don't think, I know. Such issues occur to a few phones every time there is an upgrade. From any version to any other version. There are over 700 messages in the threads about battery problems upgrading from 4.2.1 to 4.3. A lot fewer going from 4.3 to 4.3.1. And plenty upgrading to 4.2.1. And if you go back far enough from 1.0 to 2.0. Stuff happens, and it happens most often with an upgrade, but it can also happen at any random time. But the random times don't stand out because the messages are so widely scattered over time.

The cause of all of them is something that went wrong in the upgrade process, not what you upgrade from or two. See: http://discussions.apple.com/thread.jspa?messageID=12667836&#12667836

TO: Apple Engineers,

I also noticed the iPhone 4 heavy battery drain, and it started with IOS 4.3 and the screen is sluggish in response to movement with your finger. I am having to charge the phone several times a day / evening now, and i am not even using it. I have not expereinced any heat issues.

Apple engineers don't read these forums. Indeed, no one from Apple reads them, except the occasional mod when someone reports an inappropriate post. To contact Apple with a specific problem (such as you have) call iPhone support line or visit a Genius bar. Or search the forum for a solution that you can do yourself. There's also a general feedback form at http://www.apple.com/feedback/iPhone.html, but you won't get a reply there and your feedback will be used to update statistical analysis of issues.

I went to Genius Bar and had my phone changed with a brand new. Same battery drain issue. Talking with the Genius I have been told that this is absolutely an iOs problem. According to this Apple guy it is not acceptable to turn off all the major features of the iPhone to obtain a decent battery duration. I have a question for Lawrence Finch: I tried all your methods but what I would like to understand before trying is: do you consider an Exchange account even the MobileMe account.
Thanks in advance for the answers.
Waiting for 4.3.2

Exchange is particularly vulnerable. MobileMe uses a different protocol, but appears to be subject to the same problem based on posts I have seen. To go a little deeper beyond my "cookbook" instructions, there are only a couple of things that can cause heavy battery drain. One is any app that uses animation or heavy CPU use; mostly interactive games. The other is heavy data exchange, especially on 3G. If you play games you probably realize you will only get about 5 hours of playing time. This is normal, and is common for any handheld game platform.

If the phone is hot or drains the battery in Standby about the only culprit left is continuous data usage. Any cell phone will get hot when on a call (iPhone included) or using high speed data, and everyone expects this. But if it happens on Standby there is a background process that is either sending data or trying to send data. So most of the tips I posted (only some of which are original with me) are designed to stop the continuous data transmission. Resetting Network Settings will clear low level connections that are stuck.

Resetting Push email accounts will close "stale" connections that the phone is trying to use but is getting no response. I first discovered this problem monitoring the Exchange end of our corporate mail server; there were a dozen connections to my phone. Rebooting the Exchange server closed them, but few of us have that option.

I suspect that the same problem occurs with other apps that can send data in Standby. With 4.3 Apple added the Ping app, which I suspect can get into a loop trying to send and failing. It could be that Apple's servers are simply overloaded by 50 million phones trying to access Ping. I noticed a problem after upgrading to 4.2 with Game Center; I significantly improved my battery life by disabling it (I was never tempted to use it). But I tried disabling Ping and it made no difference, perhaps because I opted out of Ping from the iTunes side. But then again 4.3 and 4.3.1 have better battery life for me than 4.2.1 did.

The other troubling fact is that this is really an isolated problem; only a few phones have it. I know that there are hundreds of reports, but there are 100 million iPhones. If even a sizable minority of them had this problem there would be tens of thousands of posts (as there were when 2.1 had a REAL bug that affected every phone, at a time there were only 9 million phones).

This very same thing is happening to me! I downloaded the 4.3.1 update and suddenly my battery dies within 3 hours! What can we do? I actually went to the Genius Bar this weekend and they said the battery was fine. I asked how that could be when just before the update I went a whole day without a charge? They had no answer.

Look at the messages in the thread you posted to to find out what to do.

Thanks. I got some pointers from the person at the Genius Bar this past weekend regarding turning off apps and other tweaks in the settings, but nothing has worked. I'll go back to the Genius bar and see if I can get a new battery.
