Fans at 6k killing battery life

Both fans on my mbp run around 6k, even at system idle (w/ CPU temp around 50C). Anyone know of a way to calm them down? Instead of eight hours of battery life, I'm getting about 3...

Apart from the suggestion from eww above, this might be caused by a runaway process. If it is only recent, have you made any changes to software/hardware?
In the Utilities folder is Activity Monitor and that will list any processes running which should give you an idea of how things are.
A lot of users have experienced problems with Flash plugins and if you visited a site recently that was not well-coded, that may start problems until you quit or (in some cases) Flash crashes. (There is a download - ClicktoFlash -- that may be helpful to control Flash and let it run only when you need it.)

After making a call I put my phone in my pocket and when I bring it out to make a call the player is on killing battery life. How can I shut the player off or prevent this from happening?

Try to position your iphone that the screen is facing away from your skin.
Make sure that the back part of your phone will be the one that will contact your skin inside your pocket
Thats what i do:)

13" Air Mid 2011 hot cpu, fan on high, short battery life

Since it seems many have this problem, here is what I have found so far.
Background: 13" Air i7 Mid 2011 4gb RAM, 256 SSD, purchased in Aug 2011. Battery life is normally 5.5hours with wifi on, blue tooth off. I charge the battery until status says charged then I unplug until I get the reserve power message at 9%, most days I charge 2 times, sometimes 3 times. When I plug in an external monitor using my thunderbolt to dvi or thunderbolt to hdmi my battery life drops to 2.5-3.5hours (extra work, less battery, makes sense), back left is hot and fan is running. When I have apache web server, mysql, php, netbeans, firefox with over 30 tabs, safari with over 10 tabs, thunderbird, avast antivirus, adium, skype and other random pgms loaded my battery life stayed over 4.5 hours, activity monitor at about 80% idle. The back left corner of the keyboard stays cool during this time.
I have read the CPU power and cores are adjusted automatically based on usage, and this is what I have found to be true with great consistancy.
About 1-2 months ago my battery life dropped to about 2.5 hours. I have been trying to figure the cause. At the same time my back left corner of the keyboard is getting hot like I have the external monitor plugged in. The fan is running all the time. I look at the activity monitor and it shows 80%-90% idle. I have been on the phone with support and we tried the SMC reset, but the fan is just doing it's job of cooling the cpu. Apple phone support seemed to feel this was normal, even though I told them the back left of the keyboard was not normally this way. I have narrowed it down to.... the cpu is being told to run harder than before, so where is the mixedup signal? I began this morning reading all the messages here in the disscussions this am (and there are many with the same description), many references to activity monitor.
http://support.apple.com/kb/TS1473 - the activity monitor in this will show the process that is using the cpu the most.
In my case I had installed HP scanner software 2 months ago, which is badly written and very misbehaved, see the following link. This process would go to 100% cpu every few seconds (not all the time, so I could not see it in the summary, ), shown when I sorted by cpu % usage.
http://h30434.www3.hp.com/t5/Mac-Printing-and-Scanning/OS-X-scanner-driver-maxes -CPU/td-p/197310
I have removed my scanner drivers.
My battery life is back to 5.5hr, back left of keyboard is cool to touch, and the fan is off.
My findings, when the back left of the keyboard is hot, the CPU is running hard. External monitors heat up the cpu. Activity monitor can tell you what is using the cpu, by sorting by %cpu usage (don't trust the summary, look at the individual processes, as shown in the link TS1473) and watching for 10-30 seconds, a misbehaved app may not be at the top all the time. I hope this helps.
Thanks for all the great posts here, I was able to solve a 2 month problem.

You should probably ask this in the MacBook Air forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

Firefox 4.0 forces dGPU, kills battery life

Hi guys,
Not sure if anybody else has noticed this problem, but since Firefox 4.0 was released, it has really impaired my MBP's battery life.
Besides the egregious use of memory (which isn't a OSX problem as it does it on Windows 7 too), I noticed my MBP getting very hot from browsing the internet. After some deduction and some third party addons to OSX, I determined that Firefox 4.0 -always- activates the dedicated NVIDIA GPU (dGPU) even when it is not needed for simple web browsing.
Normally, the integrated Intel HD graphics (iGPU) is sufficient enough for simple web browsing in Safari, Firefox 3.x and older versions of Chrome and OSX switches to the dGPU when you view a flash video or need some more intensive graphics.
The problem with the dGPU is that it uses much more power than the intel, and it generates much more heat -- requiring the fans to rev up. Between the increased power demand and fan RPM, the battery drains much quicker for just browsing a website such as this one.
I used the 3rd party plugin for OSX called gfxCardStatus to determine whether the intel or the NVIDIA dGPU was active. gfxCardStatus can override what OSX is using so that I can force the NVIDIA or Intel card to be used at my discretion (or leave it on dynamic switching, it's default). The problem is, one of the nice features of OSX is the dynamic switching -- except now when it's being fooled into switching when it doesn't need to.
I was wondering if anyone knew of a solution to make Firefox not trick OSX into using the dGPU for no reason. Right now, I either need to override with gfxCardStatus or I need to use Firefox 3 which properly integrates with OSX's dynamic switching, thus sparing my battery. I rather not have to use an override because there will be times the dGPU is needed and isn't needed and having to manually switch (much less, having to know when to switch) is an arduous task.
I understand these are Apple's forums and there will be people who say "just use Safari" but Safari is absolutely not an option for me. I rather gouge my eyeballs out than use Safari.
Thanks in advance for any help with this!

My suggestion is to ask over on the Mozilla forums why FF 4.0 doesn't cooperate well with the graphics swtiching, or what can you do to keep it not demanding the dGPU.
Have you tried using NoScript to block scripts from running, might reduce the dGPU dmeand some from Flash etc.
I haven't been able to find centralized forums at Mozilla, unless I'm looking in the wrong place. Their support system seems very decentralized - you post a problem and it sits out in cyberspace until someone stumbles upon it. You can't browse like a traditional message board, I can't even categorize it so people can better find it. But yes, I have posted the problem in their "system" and didn't get much help there other than someone suggesting gfxCardStatus to toggle manually (not exactly a fix like I said).
I've heard of some people trying to use NoScript to block flash (flash is the culprit in a lot of websites that sap battery life surreptitiously but I haven't tried it personally. My issue with trying NoScript is that it is just another "workaround" and not a solution. NoScript will undoubtedly have unintended side effects/consequences where websites just don't display right or "work properly" and I'll probably end up having to toggle it on and off -- no different than fiddling around with gfxCardStatus to turn the discrete dGPU on and off.
Ditto to disabling hardware acceleration in Firefox 4 options (which actually doesn't fix the problem of the dGPU being wrongly activated, and ends up causing more problems than it solves).

Updated to OS 10.7.3; fan runs constantly and battery life dropped to under 2 hours when 100% charged. How do I get back to 10.7.2, I don't have a backup prior to this upgrade. This is a newer Macbook Pro 13", no modifications.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops.

X201 Upgrade to 8GB = Kill Battery Life

I upgraded my x201 to 8GB of RAM from 4 GB (2x2GB) and it knocked my battery life down by about 2 hours. Has anyone else had this same issue? I can't believe that going to two 4GB DIMMs from two 2GB dimms would reduce battery life by that much, so I'm wondering if there is a way to reduce the battery power draw or anything else?

try to remove the memory stick you added, then check if issue stills persists. if the battery life doesn't change after removing it, it's not because of the ram stick.

HTC Rezound OTA killing battery life/phone not sleeping

yesterday (1/31) my Rezound got an OTA update and ever since then my battery life has absolutely tanked.
all of a sudden, since the update, Verizon Location Agent runs constantly and forcing it to stop doesnt preventing it from just randomly coming back up, and thats without even touching or using the phone at all. this app/service is preventing my phone from sleeping. in about 3-4 hours i can go from a full 100% battery to it beeping at me at 9%.
please forward this info to someone higher up in the company so we can get this fixed, preferably with a way to flat out remove the Verizon Location Agent as it is not needed and is only causing problems.
the internet is filled with forums with TONS of people reporting the exact same thing. its not the battery, its not the phone. its the VLA.

I also experienced battery life cut in half after ota update and I couldn't select my ADW EX launcher as default anymore. I fixed the launcher by reinstalling and and getting a home switcher app and clearing the default launcher setting. With that said, I tried installing juice defender to manage battery better but phone was still dead after 5-6hrs on battery (yes, it was getting hot but it didn't feel to the extreme some of your are discussing).
I was holding out for the 30 day return period before rooting the phone, but since the battery was so pathetic, and people who had rooted and were running custom roms, didn't have this battery problem, I decided to start down that path. I got as far as using the HTC process to unlock the phone, at which point I was forced to to a factory reset. It got too late that night and I decided to complete the rooting later. 3 days later, I still haven't rooted it because i had other emergencies (house furnace is almost dead), but I'm SO EXCITED to report that since doing this factory reset, my battery life has skyrocketed back to normal, maybe even better then it was originally! I can easily unplug in the morning around 9AM and WITHOUT recharging it still had 36% battery last night around midnight. All 3 of the location services on my phone are enabled. 4G and wifi used throughout the day, had about 4 phone calls, checked facebook once, checked gmail a few times, did 2 web searches and texted throughout the day as needed.
So, if you're outside your return period and you loved your rezound before the ota update, it may not be the most desired thing to do, but if you factory reset your phone, you can get the good battery life back again!
So that's my experience. Let me know if you have any questions.

LG Cosmos Touch VN270 turns on all the time and kills battery life - how to stop this??

I lock the phone using the lock button on the side but then I'll notice that the display will come on spontaneously (an hour later or ten minutes later...it varies). I notice there is some symbol flashing (arrows and tiny cell phone icon at top of display) and when I unlock it I will see a screen for browsing and downloading. This is super annoying because I have to keep recharging the phone even though I barely use it. And I can't find a setting to shut whatever it is off that keeps making it do that.
It's true that the display dims a minute later but if this is happening all day then it wastes the battery. I can tell because I'm recharging the thing every other day, which I'd really rather not have to do.
Solutions??

Just to add another voice ... I've had the same issue.
Due to my terms of employment I keep the phone on overnight. Between midnight and 6:00am the backlight comes on and stays on, even though the timer is set to 30 seconds. Once, and only once, I left the volume turned up, instead of vibrate-only, and received detailed instructions on how to set up the email feature. That was not a friendly way to wake up. If I see the back light on, or the Download screen, I can shut it off with the screen lock button. Sometimes it comes back on later. This definitely kills the battery by morning.
I have worked with various Customer Support people who knew nothing about this issue. They have walked me through the remove battery, reset and reactivate phone, etc. to no success. VZW was kind enough to replace the phone with the same model. The second phone has the same issue.
The local Verizon store would only tell me to please contact the Customer Service number. The corporate account rep at work has been a black hole, so far.

Battery life cut in half all of the sudden

The battery in my macbook pro would last about 4 and a half hours browsing the internet and watching some youtube videos. but oddly just this morning after i unplugged it, it only lasted about 2 and half hours. I hadnt done anything but browse a few websites and watch some youtube videos. i tried draining the battery, and then recharging, but it didnt work.
the battery has been running hotter than normal lately, so the fan has been running more often as well. i thought maybe the fan constantly running would be the reason for the battery life issue, but would the fans really cause my battery life to be cut in half? i didnt have this problem this past summer, when temperatures were in the 80s and 90s and my macbook was hot all the time, the battery would still last normally.
what should i do about this?

ive done that. no unusual programs are running. and about watching youtube videos. why would it last 4 hours yesterday, and now. while doing something like browsing a website, something that should consume less battery. it only last 2 hours?

MBP Retina inconsistent UI graphics / battery life

I apologize in advance for the 1,000,000th thread on this topic. I (like so many others) have noticed very inconsistent smooth/choppy graphics performance with basic UI functions of OS X 10.8.2. I have tried a number of user suggetsions to alleviate this problem including turning off dynamic switching. That seems to have only a minor improvement, and kills battery life. I'm assuming that OS X (like windows machines) scales the CPU on a notebook to improve battery life. What I have noticed, is that if you have processor intense applications running/loading, the graphics lag (ie - dock zoom) improves dramatically. Has anybody else noticed this? This would at least suggest that the current retina MBP hardware components are more than capable of producing a smooth UI experience, in contrast to what other reveiw forums have suggested. Is there a way to modify CPU throttling at least when the device is plugged in? This whole issue is not a deal-breaker for me, but it's not what I've come to expect from Apple.

Update, for some reason puting the dock on the left or right side of the screen DRAMATICALLY improves performance of both dock magnification and the genie effect. This may be a software issue.

Love the phone hate the battery life

So I just upgraded to the Bionic a couple of days ago... I had a Droid X before which in itself was a great phone and awesome battery life! Now with the Bionic is a great phone as well but the battery life leaves alot to be desired...
So far I have been trying different things to see what could be killing battery life:
- Standard battery with phone on factory settings - 4 hrs max
- Standard battery with all power saving, 4g turned off, data turned off as well as wifi and bluetooth - 4.5 hours
I see inthe discussions where the battery life is very good I am just not seeing it
So i went to the verizon wireless store with some questions and was told that 4 hours was unheard of..
Rep sold me the extended battery for the Bionic and i went and left it charge
Here is what the extended battery is doing:
- factory settings - 6 hrs max
- everything turned off and set to power save as before - 9-10
Any ideas about this would be helpful

The battery life on the Bionic is great when compared to other 4G devices. If you purchased an extended battery and still have poor battery life, we know it's not a defective battery. This could easily be the software or an application that is causing the issue. I've personally dealt with a couple 3rd party email apps that drastically reduce the battery life of the Bionic. Have you tried a master reset yet? If you've already done this, and you see no improvement, I would exchange the device under the 14-day Worry Free Guarantee. If you are outside of that period, you can call the warranty number pre-stored in your contact list.
Thanks for posting! Please let us know how things work out.

IPad air ,i need to undo the latest update,battery life is the worst ,i can't finish my work like that

TOday i just downloaded the latest update of ios it was for fixing bugs but for my iPad it was for killing battery life time
i used the lowest of brightness and canceled all background refreshing and still bad
i need to undo that update immediately
it's useless now to use my iPad with that battery time

what should i do now !
I'm using the teblet plugged into recharger while using it

HT6154 After updating to IOS 7.1 my battery life has gone bezerk.

After updating to IOS 7.1 my battery life has gone bezerk. I just finished a 6 minute call with my bank and the battery life went from 93%-23%???? Then i pkugged it into the charger and the battery insicator went right to 48%. Found this article and followed it to the T to no avail.:
Guide to Solving iOS Battery Drain http://iClarified.com/39722
Please I cannot think of a better phone to use, and this is where apple will make or break me.

Please be more specific. What have you tried already? Please follow the below steps as described also in another topic by Nathan.
1. Hard reset hold both buttons until Apple logo appears.
2. Restore from an iTunes sync and backup. This made a difference for a lot of peopel, battery life got much better.
3. Limit push notifications (apps and e-mail accounts - set e.g. e-mail to fetch once an hour) to those you really need.
4. Limit location services to those you really need, and watch to see if the indicator comes up.
5. Get the app System Activity Monitor to look for a runaway process that is using a lot of CPU.
6. Suggestion by others to reset all settings.
7. Suggestion by others that iCloud may be involved, and to try to turn off some iCloud settings.
8. Limit or turn off 'background app refresh'.
9. Add apps back in carefully to identify an offending app that is causing CPU or network activity that kills battery life.
10 Also make sure that e-mail is fetched (e.g. every hour) or set to manual instead of pushed.
11 Do you have a good carrier reception? Have you tried to manual set your carrier within your iPhone instead of the 'automatic'?
12 Have you checked if the timezone is set to manual instead of automatic and see if this makes a difference in battery use?
In my case it was a bug with an app that caused the battery drain. I also noticed that the use and stand-by time were exactly the same which is ofcourse not correct. This was all caused by this app which was using GPS tracking all the time. Unfortunately an app such as System Activity Monitor did not indicate that in my case but someone posted this solution on a Dutch forum that the previous version of the app 'Scoupy' had a bug and caused this battery drain.
If you haven't tried every single one of these, please do not post that battery life is terrible.

Battery life with Lion OS is very low, why?

I recently installed Lion OS, since then my bettery life has dropped from 7 hours to 2 1/2 when fully charged. Seems like the processor os running full speed all the time. In fact the computer is very hot, fan is running, etc. Thoughts?

D Funk Orinda,
It could be a 3rd party software. For me it was the Adobe Flash Player / Safari causing my woes. I downloaded and installed the Adobe Flash Player 11 beta and all has been fine since. No more system lock ups, high CPU usage, CPU heat, fans running loud or battery life issues due to flash player in Safari. I also performed a 'clean' install using a DVD I created from Discussions in this forum.
