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.

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'.

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:

HOT iPhone and poor battery life after 1.14 to 2.1 firmware upgrade

I recently upgraded my Original iPhone's firmware from 1.1.4 to 2.1. I did a restore rather than a simple upgrade (backup, restore to version 2.1, restore backup).
After the restore I noticed that my battery life was terrible and that the phone would get very hot (near the top of the phone) sometimes, as if the battery was discharging very quickly. I read a few posts that suggested Push might be the culprit, so I turned Push off (I'm not using MobileMe), and this seemed to solve the problem. However...
I now notice that whenever I play Apple's Texas Holdem from the App Store or play YouTube clips the same phenomena occurs, and that nothing short of a hard reset will stop it.
Oddly, if I refrain from playing YouTube clips or playing Texas Holdem battery life is much better than before the firmware upgrade.
In short, it looks as though there is something wrong with the 2.1 firmware. I see sporadic accounts of similar behavior on the various discussion boards, so I know I'm not alone.
Is there a fix for this behavior?
Thanks in advance...
James

Sounds more like an app stuck processing that shouldn't be....does happen from time to time. Behing hot means it is constantly processing.
To fix:
Try a reboot (described below).
Think of it this way, the iPhone is more of a computer than a phone. It suffers from being a new OS and nobody can deny there are not bugs and memory leaks. The longer left running, the more things start to fail or slow down (I have had the iPhone since day one of original phone and I am just speaking from my experience). Thus I equate it to like when Windows95 came out...not sure of your age or if you remember those days...but back then it was a running joke of how many days you can keep Windows 95 running before you had to reboot. I am sorry to say but the iPhone is the same way right now (but getting better with a few hiccups back during the 2.0 release). So for me, I reboot daily when I leave in the morning and take it off the charger. By doing so I rarely see any lag or problems.
A reset/reboot is:
Go to Home Screen
Press and Hold Home Button
Keep holding and press and hold Lock Button
Keep holding Both
You will see Slide to Turn Off (Don't let go to slide, just keep holding)
The phone will turn off (in time, but screen will look like it has some white lines)
Keep Holding
When you see the Apple Logo, you can let go.
Turning off via the Slide to Turn off while good and fine to turn off, is more like the Sleep Mode on a computer. Thus any locked up issues in memory remain when you turn back on. A reboot as described is like doing a real Turn off and Turn On on a computer.
You may also wish to read this tread about reboots and odd application behavior.

For me, 2.1 works great.

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.
This are Monitor Utility screen print.

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.

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...

My Ipod nano touch is not charging, not showing in my PC or laptop. Last I saw an apple icon and low battery signal. There after the screen is black and no power not taking AC or PC charge. What Can I do?

If the Reset didn't work, you'll need to do a Restore.
From iTunes, select the iPad and then select the Summary tab. Follow directions for Restore. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finished, you will be asked if you wish the contents of iTunes to be copied to the iPad.

HT4060 ipad does not seem to be charge. has been plugged in for about 5 hours and low battery photo remains...cannot turn on or off... only low battery photo and apple symbol or blank page appear

ipad does not seem to be charging. Has been plugged in for about 5 hours and low battery icon remains same...alternates with apple symbol or blank page. cannot turn ipad on or off

The iPod Touch kept trying to reboot yesterday but would only show the Apple logo screen then shut off - it finally drained the battery overnight I am guessing. Connected to USB the battery charging icon flashes.
Took it back to Best Buy, but they wouldn't touch it or replace it since it's under warranty.
To any potential buyers - beware. My best advice is to look somewhere besides Apple. Every Mac user I know has had to return a Mac, laptop, etc. Really poor quality control, and the retailers agree (Geek Squad told me they have had the same experience with Apple products).

I've just upgraded to the Iphone update and now battery life of the poor is very poor (3 hours). Is there anything I can do to fix this?

HELP!!!!!

Hey man...I have the EXACT same Ipod with the EXACT same problem. I went to the apple store and they told me I had to wait 3 days to make an appointment with a "Mac Genius" to look at it and that with all the repairs done it would probably cost me $150. Frustrated, I went home and did some research and heres what I found:
http://www.youtube.com/watch?v=3ljPhrFUaOY
http://notpopular.com/blogs/josh/2006/03/29/fix-your-ipod-by-spanking-it/
I kid you not. So basically I put the wall charger on, let it charge for 3 hours. Took it off the wall plug and then slapped the $#!t out of it 4 or five times. Then turned it on. Same sad face. Tried a combination of the reboot procedure and slapping around and now it works! Good luck and hope it works for you too!
I feel like going to the apple store and slapping the crap out of "Mac Rip Ppl off Genius"

Your MBP is NOT meant to be used on your lap.
Try SMC and PRAM resets:

Hot battery and short battery life after download of Mountain Lion.

Hot battery and short battery life after download of Mountain Lion. Any suggestions?

As in, shortly after install?
Note after you install Mountain Lion it's likely that the Spotlight index will be rebuilt. This will take some time and the machine will run hot. After this completes, which could take 1-2 hours, things should return more to normal.
If they don't, I suggest running Activity Monitor and seeing if you can trace what is eating up CPU cycles.

I upgraded my macbook pro from OS Lion to OS Mavericks. When unplugged, it heats up exceedingly and the battery life is extremely short. What to do?

Installation of the new OSX is very heavy hdd load, in addition spotlight reindexes all the files on your computer - it may be a few hours. If in the future will be the same macbook hot, you should contact your nearest Apple Authorized Service Provider.
May be required to clean notebook cooling system.
You can also install any monitoring utility sensors to your mac such as Hardware Monitor and look at the value of the temperature sensors.

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 ??

Noisy fan, very hot case and low battery life
