IPhone 4 hot and low battery life?

Why does my I phone 4 have such a small battery life? And it is running hot

Hello Bmay121,
Thank you for providing the details about the issue you are experiencing with your iPhone. I found a couple of resources that may help address this issue.
First, I recommend following these steps if your iPhone has a short battery life:
Battery life seems short
Click ( www.apple.com/batteries/iphone.html) for tips on how to prolong iPhone's battery life.
Try turning iPhone off and then on again.
Connect iPhone to iTunes and restore iPhone.
If the screen shows a low-battery image, the battery is low on power and needs to charge for up to ten minutes before you can use it.
When charging iPhone, make sure to leave it charging until it is fully charged. You'll know the battery is fully charged when the battery icon in the upper-right corner of the screen looks like this .
Note: When charging using a computer, don't connect iPhone to a keyboard. Also, the computer must be turned on and not in sleep or standby mode. If iPhone is connected to a computer that's not turned on or is in sleep or standby mode, the iPhone battery may drain.
You can find the full article here:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
You can also find useful information about the iPhone's operating temperatures in this article: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. If the interior temperature of the device exceeds the normal operating range, the device will protect its internal components by attempting to regulate its temperature. If this occurs, you may notice the following:
The device stops charging.
The display dims or goes black.
If the temperature continues to be a concern, you can isolate the issue by restoring your iPhone as new:

Thank you for using Apple Support Communities.
Best,

Noisy fan, very hot case and low battery life

Hi
Got a new Aluminium Powerbook 1.67 in Feb of this year, plus 2 spare
batteries.
Initially I was very happy at how quiet it was and how cool it was running..... however....
The fan has become really noisy and the case gets very hot ( near the power in )
The batteries will only ever give me exactly 1.5 hours of use even after firmware upgrades and restting the PMU, PRAM etc. ( this is with light use )
Looks like it'll have to go back to Apple for the fan, I just wondered if anyone else had similar problems and whether they got resolved to their satisfaction?
Regards
Graham

Graham,
Excess heat will certainly reduce battery life, so you should get your pB looked at ASAP and have the fans taken care of.
Definitely think about getting AppleCare.
Did you ever properly calibrate your batteries?
Simply run them past the low-battery warning until the pB goes to sleep. Then plug in the Adapter until fully charged. May have to repeat this a couple of times.

IPhone 4 hot and low battery

My iPhone 4 is running hot and battery life lasts 4-5 hours? What's happening

Hello Bmay121,
I'd recomend restoring the phone as new, then install applications one at a time until you discover the culprit. As always, I strongly recommend making sure you have a backup of your iPhone in place prior to restoring the device as new.
Choosing an iOS backup method (Should I use iTunes or iCloud to back up my iOS device?)

Wireless driver triggers warm/hot macbook and low battery life after OS 10.8 mountain lion upgrade

Hello frustrated Macbook users.
I have tried to get help on other Apple discussions but no one seems to want to help, they aren't actually reading my posts, or they hate me for some reason.
No matter.
If you have a warm Macbook that has 2.5 hours of battery life where you used to have 4 or more, please do this simple procedure and write the result below.
Turn OFF Airport wireless networking
Perform an SMC reset (Power Manager)
Connect an ethernet cable and use your Macbook normally. (but do NOT turn on wireless networking again)
How is your battery life after doing this?
I have a user over here who reclaimed decent battery performance if he doesn't use his Airport wireless.
I need confirmation.
If so, I may get a USB wireless adapter and see if the battery life stays good.
Bonus points: If you have a Mac compatible USB wireless adapter and got good results by turning off the built-in adapter, want to test it for me and report the results?
Thanks and good luck!

UPDATE:
Problem persists when using Recovery Partition.
Chance sthat it is third party softwae or updates is more or less eliminated.
Update 10.8.3 beta fixed the problem for one lucky early adopter.
Hypothesis: New battery charging algorithms programmed into Mountain Lion OS10.8 triggered problems from design flaws that were NOT an issue for OS 10.7 and before.
Battery replacements were successful where the replacement battery was built within tolerances that did not fail under 10.8's new charging algorithms. Other bateries did not meet those tolerances so you would get spotty results from battery replacements. It worked sometimes, but not always.
OS 10.8.3 may have adjusted these algorithms to be less demanding on the features of the battery that were failing.
Official word from Apple is 'mum'.

HOT mac & low battery life.

My mac pro is suddenly VERY hot and also the battery life is very low. I left my mac on charge all last night, and it only gave me 1.5hr battery life?

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

High CPU Usage and Low battery life

Hi to all, I have this problems, my cpu is always over 40% an battery life is short. Before I installed 10.6.2 my battery duration was 4 hours, now is 2 hours. I tryed SMC reset, but the problem is on the CPU usage.

Those permissions messages may be ignored. They are normal.
Because everything is OK in safe mode you need to track down what isn't active in safe mode that may be causing the problem you are having. Of importance are:
1. Incompatible third-party extensions (drivers) such as may be used for third-party peripherals.
2. Incompatible items located in the /Library/StartupItems/ folder or /Home/Library/LaunchAgents/ folder.
3. Bad fonts located in the /Home/Library/Fonts/ or /Library/Fonts/ folders.
4. Incompatible item in your Accounts' Login Items section.
5. Corrupted caches located in the /Library/Caches/ and /Home/Library/Caches/ folders.
To test the corrupted cache possibility simply remove the above mentioned cache folders to the Trash (but do not delete) then restart the computer normally. If the problem is resolved then you can empty the Trash.

Restore the phone as new, do not use backup.

Ipod touch 2G overheats and loses battery life

recently purchased bookworm for the touch. I usually listen to tunes while playing most games. I noticed that when I do this with while playing bookworm the back of the touch gets hot and my battery life goes from hours to one hour. By hot I mean kind of uncomfortable to hold hot. Any suggestions?

One thing I can think of is to remove any case on the ipod when you are using so that the heat can escape easier. I notice mine gets pretty hot when I charge and I used to leave the case on and had a few battery-life problems because of it

IPhone 5 hotter than Venus and dreadful battery life after beginning to use photo streams?

You may be able to tell from the title i have an issue.
Set up the photo stream today after my bro in law shared pictures. Phone immediately heated up to ridiculous levels and my battery life has been dreadful.
I've had the phone since start of June and had good battery life and no issues with heat, done the ios7 update last week (with no problems) so I reckon the issue is with the photo stream feature but I'm no tech wizard.
I've done a few searches for an answer but not found anything.
Any help would be great
Cheers
Stevie

i am having same problem lately with my Iphone 5 and IOS7. I see my phone gets very hot when using the camera (or the gps apps). but even when I turn the camera off as well as GPS, the drainage is growing and when it gets to 24% it shuts down !!!! dead, I connected to the usb cable and it started but showed 0%.... very frustrating indeed !!!! would I be experiencing same issues with the new 5S I ordered already ??
I see your comment about the "photo stream" - it sounds potential problem - I wonder if any other colleagues will bring this up as well ?!
I turned off the Photo Sharing - will see if it's better, I did not want to turn off the Photo Stream becasue I did npt want to lose all my stored photos in te Icloud.
is there something wrong with the camera ??

My iphone is currently using battery life much more quickly than inthe past, and it also has an icon tht is starying on the screen, to the left of the battery charge percentage, that looks like a lock with a circle around it

i have an iphone that is using battery life much more quickly than in the past, a full charge is going to zero in a half a day or so, with out much use.
an icon is also appearing next to the charge percentage in the top right, and the icon is a circle around a lock
can anyone tell me what the problem is, and what the icon means?

The Icon meas your display orientation is locked to vertical so it wont change when you turn the phone sideways.
First thing you should check with the battery life is multitasking, which also happens to be where the orientation lock can be turned off. check out http://support.apple.com/kb/HT4211 and go from there

I got my iphone 5 3 weeks ago and the battery life is very short. It drains out very fast. Does anyone know if it's a problem with the iOS or with my phone? Because I'm a bit concerned

I recieved my iPhone 5 3 weeks ago and the battery life completely *****! After doing a few things and maybe using it for about 30 minutes the phone start overheating like crazy then the battery starts dropping very fast. Does anyone know if it's a problem with the iOS or with my phone? And is anyone else expierenceing these problems?

It sounds like you have an app that is incorrectly continuously using data and power... from normal use the phone should NOT be getting that warm... only constant video playing via data like Netflix for example would result in that...
I'd say that you should remove all apps in the recent app tray... tunr phone off... then once you power back on...
Hold BOTH home and sleep wake buttons together until you see a white apple symbol... then release both buttons...
This will ensure you have no apps running...
I've experienced a hang up with mail while out and about that has resulted in this on my iPhone as well... Once I performed these steps it was fixed... it seemed like it got stuck and that's what caused the warm phone and battery drain...
I notived that when it gets stuck (mail app that is) I will see the text connecting at the bottom and it never changes to "updated" like it should... this is my trigger that it's gotten stuck.
Have not really figured out what causes mail app to get stuck yet...

I have a motorola H17 bluetooth it is paired to iphone 4s. The icon shows that it is connected. When making a call i tap the speaker icon and the bluetooth icon is not there. The motorola H17 tells me i am connected and the battery life when turned on. Any advice? Thank you in advance

here is an interesting thing: take the iphone and set lock screen to never. Now make an email with siri--be sure to activate her with call button. get to the body and get some text in there. then just stop talking. LOCK SCREEN APPEARS!!!!!! and of course you draft is gone.
There does seem to be a work around for some--maybe all these issues. Don't use the call button--use the buttons on the phone.
Siri seems to behave properly with scenerio above---sans call button. She does not go to lock.
