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.

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

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:

Is ipod touch low battery life normal?

I just bought my new ipod touch. I found the battery life is quite short. Every day i have to charge it twice. Now I am keeping to use my ipod touch as less as possible to manage charging it once a day. This is really not compared to a regular phone, which you probably can use 3 or 4 days to recharge again.
The so-called dock adapter inside the box is quite tricky! I thought it is the power adapter. Normally when you buy a cellphone, it comes with the power adapter. But for ipod touch, you have to buy power adapter separately! I even don't know what's the use of this 'plastic' dock adapter. i called Apple and asked "You call this plastic piece an adapter!". It's a little funny!
During my first week using my ipod touch, it got stuck or crashed TWICE, two times! One time is when it downloaded an email with a 8Mb attachement.
In addition, I feel quite confusing with so many accounts with Apple, such as Apple store account, iTune account, iChat account, MobileMe account, and even this discussion forum account. Now I have 3 Apple IDs!
The use of MacBook is so far so good.
This is my experience with Apple's products!
Welcome comments and sharing your experience! i just couldn't help keeping myself silent.

Is ipod touch low battery life normal
Yes and no. Even in normal usage, Safari and videos can kill the battery in 4 - 5 hours, whereas music with the screen and WiFi off should last for 22 hours. Most iPT's can last for days in sleep mode, even with WiFi left "ON".
My previous iPod Touch had no battery problems -- the charge would only drop significantly when being used, not while sleeping. Now I have a replacement iPod Touch (the previous one couldn't install the 2.0 Update), and this one won't even last overnight in sleep mode.
Here's what I did in my last test: Turned all the WiFi services off -- Push: OFF, Fetch: OFF, Location Services: OFF, Ask to Join Networks: OFF, WiFi: OFF. Fully recharged the iPT, disconnected it and left it shut down overnight. Booted it up the next day, full battery (Okay so far). Next, I left the iPod Touch in sleep mode for the entire day (8am - 6pm), still full battery (Great!). At 9:00pm, turned on WiFi (and none of the other items mentioned above), used Safari for about 15 minutes, battery went down one notch ~ 90%. (Still normal) Put the iPT into sleep mode, but this time with WiFi left "ON". Woke up the next morning, and the battery plummeted to 10% in about 5 minutes. (NOT GOOD AT ALL).
My previous iPod Touch would have still had 90-80% battery the next morning. And while I would generally suspect the 2.0 Update being the culprit, everyone else I know has been running 2.0 without any problems -- no installation problems, no battery problems. I've been cursed with both issues in two separate iPods.
(I should also mention. I have not yet had a chance to install any media or applications on this iPod Touch, so there's no chance an errant application has somehow triggered a battery drain. This is just a plain iPT with the 2.0 Update and a restore of my Safari bookmarks.)

15" MacBook Pro runs hot, fan is loud, and incredibly low battery life

My 15" MBP was bought in March or April (can't remember) from Singapore Apple Store. Here are the stats:
MacBook Pro 15-Inch, Late 2011
Memory 8 GB 12222 MHz DDR3
Software Mac OS X Lion 10.7.5 (11G63)
Also I'm using about 1/2 of the available 750 GB of storage.
Here's what's up:
1. The fans boot immediately after the computer is turned on and never stop, making everything much too loud...like a plane is taking off or something.
2. The computer is WAY too hot. Right now I'm running Astrill, Chrome, Activity Monitor, and System Utility, and when I put my hands on the thing it feels like my fingers are going to melt.
3. The battery life, even at a full charge, is about an hour overall, which ***** for so, so many reasons.
Here's what I've tried:
1. I took it to the Shanghai Genius Bar, but I think that the language barrier is impeding my ability to really say what's wrong. I backed up, and they wiped the hard drive, re-loaded the OS and put all my old stuff back on the computer. They also deleted SOMETHING from the Preferences part of the library, but I don't know what it was. Everything runs much faster now, but the fan, the heat, and the battery are still having their issues.
2. I've checked the "all processes" CPU usage. There's nothing unusual (as far as I can tell), so I'm at a serious loss as to say why the computer is running so hard. Even with all the processing running as you see below, the fan's still blasting and I've lost 50% battery life in the past 40 minutes.
3. I've tried the fix that requires deleting com.apple.desktop.plist and com.apple.desktop.plist.lockfile. It changed the way the desktop looked and absolutely nothing else.
PLEASE, PLEASE, PLEASE help me! I'm a graphic designer and often run the CS6 Suite. (Currently, however, I am NOT running any Adobe programs and I'm still experiencing the problems.) It's really important that I am able to run Photoshop, Illustrator, and InDesign at once, and it CAN, but with the heat problems I'm having without ANY of the graphics stuff running, it worries me.

Just took another look at iStat Menus (I've only had it for a couple of days - I used to use the old iStat Pro widget) and it seems as if you can make fan speed defaults and use them instead of relying on your MBPs sensors to take care of the fans... see...
Might want to use that 'medium' speed (there by default as I know I didn't add it) and keep an eye on your temps. If you start heating up to much, go back to the 'Default'.

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!
meta: short time install snow leopard hours overheating shorter shortened lower

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'.

Low battery life, heat or noise with Macbook pro? SOLUTION HERE

Low Battery?
Warm unit on Idle?
Loud fan?
Likely solution is here..
I have a new 15" and had these issues, found the only working solution in the thread below, safe and easy to use. If you are worried do a
time machine backup before doing this.
Go here
https://discussions.apple.com/thread/3191543?start=0&tstart=0
Read post #2, put the command into your Terminal (Found inside launchpad)
- That command is the following "sudo launchctl unload -w /Library/LaunchDaemons/com.citrix.agadminservice.plist"
type password when asked ( you wont see any characters but it will be accepted when pressing enter)
Restart, battery, heat and noise issue is completely solved, lion is fixed.
You now have a very high quality product, that functions like it should. Macbook Pro still owns.
Hope this helps everyone out.

Same problem with shortened battery life here with 10.6.2 (2009 unibody 15" MBP 2.53 GHz.) Shutting down and removing the battery seems to have brought fully charged battery life back from less than 2 hours to over 5 again. Didn't bother holding down the power button with the battery out though.
A few notes:
1. Prior to the shut down + battery removal, I had noticed unusual warmth despite the CPU being only lightly loaded. Activity monitor showed no app using more than 4% of the CPU, with just a few apps running (Safari, Mail, iCal, Finder).
2. Months ago, just a PRAM reset seemed to fix the problem, possibly with 10.6.1 or 10.6. Can't remember for sure. But PRAM reset doesn't help any more with 10.6.2.
3. I have never reset the SMC.
4. I don't recall this problem happening with any of the 10.5 releases. Just with 10.6.x.
5. The bottom of the MBP's enclosure is cool again after the shutdown + battery removal.
6. I am also running 10.6.2 on a 2008 aluminum iMac (20" 2.4 GHz) and haven't noticed any unusual temperatures, but it's much harder to tell. And of course, there's no battery life to measure.
I'll see if the problem returns again, but it really seems like a Mac OS X problem instead of a firmware or runaway app problem. Maybe some daemon is stuck in a busywait loop or something?

Why is my mac's battery life decreased and got slower after upgrading to lion?

Thank you for helping,
I am using MacBook Pro (13-inch, Mid 2010) and beginning of this summer I upgraded it from snow leopard to lion (from apple store). After installation my mac got slower,it consumes the battery very rapidly and starting time increased. I searched the reason on the net and this time I did a clean installation. I but the problem insisted. last week i updated to 10.7.5. this time i see that coloured spinning wheel even i logging in. I did all the updates and battery calibration as mentioned in apple support communities but nothing have changed. I don't use any grafic programs etc. I only use safari, firefox, iphoto, iwork and microsoft office for mac. My english and my computer knowledge is not very good. So, if you answer my problem please will you explain as much as simple.
Thanks anyway.

A couple of things...
...first, you might want to make certain that your internal drive is selected as the Startup Disk under System Preferences. If it's not, this can sometimes lead to a problem of your MBP 'searching' for a boot drive at startup. Second, you might want to read ds store's article - Why is my computer slow? A very handy reference guide with some good tips.
As to your decrease in battery life - that has been reported by some users as a problem with both Lion and Mountain Lion. See the "More Like This" to the right of this page.
Can't offer any real solutions - read Mr. store's article and see if you can find anything that helps. You might also want to download the free "Battery Health" from the App Store and keep an eye on your battery when you're using it.

Nokia 5800 VERY low battery life! Please help!

I bought a Nokia 5800 last week off a friend.From day one it has had problems.
I've managed to somehow fix those but now the biggest problem i have is that the battery life is VERY low. Y'day i charged the phone overnight and today i was using Whatsapp(for abour 2 hrs) and listened one song and now(it's noon) the battery is EMPTY!.
I ve heard that this phone has really good battery life but i only used the ohone for about 4-5 hrs and the battery is already empty!
What do i do? please help me!
Does it have something to do with lose connection?

I just bought a new battery on Saturday

Does playing heavy-graphic games on iphone 5 until it's hot reduce the battery life?? plz answer :)

so yea , does doing that gradually damage the battery of the iphone 5 and overtime curtail the battery life and lifespan?? I play fifa 13 on my iphone 5 for lengthened periods until I can feel it get hot almost every day. Is doing that actually harmful to the iphone battery and its lifespan?? im curious becuz before I've seen on the apple battery care web page that heat is the factor that will degrade battery performance the fastest on idevices, so Im just afraid concerned. plz answer

Batteries have an expected number of charge cycles before they degrade and you begin to experience diminished battery life. While heat is a factor that will afect this, overall the number of charge cycles the battery has will remain fairly constant.
You will find if you are using the phone the way you are you would be charging the battery more often and it is this increase in the number of charge cycles that would be shortening the battery life. Does that sort of answer your question?

MacBook Pro (CoreDuo) sometimes runs hot, with short battery life

I am having a somewhat intermittant problem with my MacBook Pro (CoreDuo 15"/1.83/1 Gig). I keep track of the computer using the widget iStat Pro, as I have found CoreDuo Temp to be pretty unreliable as far as temperature is concerned. Now, usually, I leave the computer on, but asleep and charging. Twice now, when I have awakened the computer for use on battery, it started running very warm, and was using the battery charge very quickly. For example, a few minutes ago, the battery was at about 90%, and the time left on the charge was well under 2 hours, while the temperature of the CPU was about 78 deg C. This was using the computer for web surfing. About 10 minutes after a restart, the CPU temperature is down to 53 deg C, and the battery life is up to 2:46, with 77% charge, values that I am more used to seeing. Since this is the second time I have seen this happen, I am beginning to get a bit worried. The computer is under AppleCare, so any problems will be covered by Apple, but this seems to be pretty unusual behavior. Should I contact Apple about this?
Thanks in advance.

First you ought to find out if you have any processes running that are hogging CPU time. Use Activity Monitor. Select All Processes from the drop down menu. Click on the CPU % column header to order a descending sort. Observe what processes may be using large amounts of CPU time when you observe the computer running very hot.

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.

IPod stays on Pause ... Lower Battery Life?

Hey, We have an iPhone 3G and were wondering about the iPod part.
When we stop the music from playing we pause the song and navigate to the homepage. I notice though, whenever I pull out / put in my headphones the iPod feature opens and plays my last song. Or whenever we click iPod it plays my last song. Is the song thats staying on pause lowering my battery life? Or no?

Bump!
has anyone had this prob? Please help me. Or where can I call or send it to and have it fixed.

Low battery life on new 4th generation nano?

I got a 16 gb 4th gen nano yesterday. When I first turned it on, I was pleased to see that the battery was almost completely full. I took it to work, and listened to it for about an hour total, coupled with playing games on it, the charge level had drop to near half, not once, but twice (I'd brought a charger with me - the Apple charger that was recalled yesterday, ironically).
Today, it was fully charged thanks to the new 4th-gen compatible new car charger I bought when returning the recalled adapter for a refund. With the slightly over an hour of playing music and playing games for not even an hour total; the battery is now out - I've got the low battery message on screen. Do new batteries need a few charge cycles before they hit max capacity or something? Tomorrow I may recharge it and just let it play on shuffle while I leave it alone and see how long it lasts, but it still seems like it lasted pretty short.
Any thoughts?

I am having a similar problem with my nano 4g battery. I just bought this on Monday. Got it home, set the language, time zone and time then plugged it into my computer to synch it. When I got it out of the box it was 3/4 charged. Before the synch was even done the nano showed it was fully charged. After synching I unplugged it from the computer and clicked a few buttons on the nano and immediately a little sliver of the battery display had gone down! I hadn't even played 1 song yet.
I plugged it back into my computer and the nano still showed it fully charged. yet when I unplugged it, it still showed it as a little bit of the battery having been used. I played 1 or 2 songs and the battery went display went down a little more.
That night I plugged the nano into the wall with my adapter (we've had this one a while so it can't be one of the new ones that was recalled and we've charged other iPods with it) and let it sit overnight. The next morning I unplugged the nano clicked around on it a few times and again the battery display went down a sliver. I thought maybe it was a display issue, figured I'd take it to work and give it a try. After about 1-1/2 hours of listening (occasionally pausing it), the battery display was down to about 1/2.
I charged it again on the computer. This time it took between 1-2 hours on the computer for it to show fully charged. Brought it to work again today and the same darn thing is happening with the battery display. I have not tried running it overnight or for several hours to see if it drains completely.
I have it set to Energy Saver.
Are lots having these battery issues? Not sure if I should take it back to Best Buy and exchange it for another one just yet.
Brian, if you read this, did your restoring end up really helping? Seems like you shouldn't have to do that and re-install software that was already on the nano when you purchased it, but if that completely fixed your battery problem, I'll give it a try.
Any suggestions would be appreciated. Thanks!

HOT mac & low battery life.
