iOS 4.3.1 causing iPhone overheating for some users? Here’s how to fix it

iphone-4-fire

An Apple discussion board is on fire with issues regarding iOS 4.3.1 and the fact that it may be causing some iPhone handsets to overheat and suffer short battery life. Many users are saying that battery life on the smartphone has decreased dramatically, and that phones will occasionally overheat while in use.

Here is what the original poster of the thread said:

My iPhone 4 for the last few days has started to get very hot in use and the battery is gone very bad. Leaving the phone on standby can see the battery drain nearly 20% in an hour. This is gone to the stage where I have to turn it off at times just to save battery during the day. It only began to happen when I updated to iOS 4.3. I updated to iOS 4.3.1 yesterday and it still has the same issues. Anyone else having the same problem?

The thread exploded with advice — from disabling Exchange mail accounts to turning off notifications for apps and deleting culprit apps — from several users. Folks, the solution is really much easier than that.

Every time you update your iPhone software and restore it from a backup, there is a chance that there may be some corruption going on from the backed up info. If your iPhone begins to overheat and your battery life goes to the pits after a software update, the fix is easy: restore your Apple smartphone and set it up as new instead of from backup. Sure, it will take much longer to re-sync all of your contacts, apps and music, but it will undoubtedly fix your overheating and battery life issues from an update.

This issue pops up almost every time there is an Apple smartphone software update, and I remember first seeing it after updating my old iPhone 3G to iPhone OS 2.1. I remember the change-log saying that battery life, which was a major issue on the iPhone 3G, was supposed to be significantly improved. Instead, after the update, it became worse! Finally, I learned that a restore as new, instead of restore from backup, fixed the problem. And every single time I’ve had that battery/over-heating issue with iOS updates, I’ve restored my phone from new and the issue always went away.

    If you restore as new don’t you lose all your app settings and SMS history?

      Unfortunately, you do lose your app settings and SMS history. You’ll have to log into all your apps again (Facebook, Twitter, Foursquare, etc.) and your SMS history will be wiped clean. It’s annoying, but it’s better than having to charge your phone every 6 hours and dealing with an overheating handset, which can shorten the life of your battery or damage the device itself.

        how stupid are you marc to comment something so useless like that

        • http://twitter.com/WillieFDiazSF William Diaz ?

          Marc is hardly stupid. He is just stating the most simple and basic troubleshooting method of all. That doesnt make him stupid. He is informing someone else of something that may not be so obvious. Remember something here, the iPhone is many peoples FIRST smartphone. While to Marc, you and myself, this kind of troubleshooting may be simple, obvious, and asinine, to someone who never had issues with their phone, or someone who has never owned a smartphone before, this is something new that may help them fix the issues.

          Sadly, this is what Sprint is saying I need to do to my phone, for their overloaded network in San Francisco.

    Best piece of advice for a phone that overheats… PUT IT IN THE FREEZER!

      But wouldn’t that cause condensation?

    Mine overheated today-5/6/2011. I was playing a game for about 8 minutes and got the message that your phone is overheating and is not available to use. Before that happened my brightness on my screen went down dramatically. Thought it was a bug in the game I was playing.

    Marc Flores,
    Please explain to me why my brand new iPhone 4 w/ iOS 4.3.3 started overheating after I plugged it in to charge the day of purchase? No updates, no restore, no pc interaction. Just plugged it in, felt the actual charger getting toasty at first, then the phone itself became very hot to the touch. Restore as new undoubtedly fixes my problem? I think not.

    Just bought a white IPhone 4 and experienced overheating and rapid battery drain.  Closed all programs, reset settings, to no avail.  However, when I removed the SIM card, the problem went away – any suggestions?

  • Martyn_Saxman

    Sorry but this is nuts – the iPhone 4 is far from perfect and we pay an extraordinary amount of money for it and it’s then up to US to fix it??? Would you buy a Ferrari and expect to have to change the starter motor yourself every two weeks? No, I didn’t think so!

    my iPhone 4 is overheating.  Apple sucks

    Flores and all the so-called Geniuses at our local iPhone Store are a disgrace.  After several hours-long resets, which they all say are the only way to correct the problem, a friend in our IT department showed me what to do.  On the iPhone 4, all you have to is hit the round bottom button twice, which brings up a bar on the bottom that displays the first four “open” apps.  Hold down the first app icon until it starts blinking and displays a red minus sign.  Click the minus sign to close down the app, and continue closing down all the rest of the open apps (I’ve found as many as 30 open apps at times).   Proceed to Safari, and clear the history.  You may have to shut off the unit after this, but generally, the phone cools down to normal in a few minutes.  How I wish that Apple’s employees and other “experts” knew the bare-boned basics of this device!

      you’re an idiot if you didn’t know how to close an app in the first place. Expecting the Genuiuses to tell you to make sure apps aren’t running in the background is like letting your car idle all day running out of gas and then going to a mechanic and telling him your car ran out of gas even though your didn’t drive anywhere…
