How to extend battery life in Mountain Lion?

I have an Macbook 5,2 and recently I update Mac OS X from Snow Leopard to Mountain Lion (10.8.3 12D58). Current main problem is my battery life reduced from 5 hours to 1:58:00. This is crazy. Are there some applications runs on the back ground? How to uninstall useless applications and extend battery life? Looking forward to get help from this forum.
Best Regards

Runaway applications can shorten battery runtime ...

Battery Life ***** on Mountain Lion!

About a week ago I took my new mid 2012 13' macbok to get checked out. The reason for is because the battery was not holding up like I read in the specs. At this time my macbook pro was running Lion 10.7. I upgraded still samething nothing changed until I took my macbook in like I meantion. At the time I took it in I was running Mountain Lion already. So they gave me a new battery everything seem well until a week later I monitor my battery health very closely, so I seen it was dropping quick again. When i got the battery it was in great health and still is but it was at 106% overall health n a week later it was at 95%. I am concerned about what is going on especially with only 6 cycles? Why is this hapenning when I do what is told to do to keep they cells active and have a happy battery. Apple plus look into this battery problem. How many are experiencing the samething?

from experience - when I first got my new Macbook, charge capacity is at 5700 mAh.....after using it for a few months now, my charge capacity has dropped to 5300mAh then back up to 5600mAh and today at 5536mAh...it changes daily and has not affected on how long my battery would last - I'm still getting 5+ hours when I'm doing some online work. 6 hours when just browsing the web.
there is nothing wrong with your battery. battery life does decrease when Mountain Lion is installed but that is more software issue than hardware.
you're under warranty and apple was nice enough to replace your battery.....
why not use your Macbook normally and not worry too much about it if you're gettng 5+ hours in a single charge. Again, you're still under warranty - if things go bad - just get it diagnosed and replaced.
good luck

Poor battery life after Mountain Lion update

I updated OS on my 2011 13" MacBook air from "Lion" to "Mountain Lion."
My laptop used to last 5-7 hours with a single full charge. After installing Mountain Lion, I can't even last 3 hours.
I noticed that other people are experiencing the same problem but I can't seem to find a solution.
Any suggestions?

There's a huge thread about battery life here: https://discussions.apple.com/thread/4135250?start=0&tstart=0 . Hopefully it will be fully addressed in 10.8.2.

Battery life in mountain lion

My MacBook Pro battery drains faster now with Mountain Lion than Snow Leopard. I have the last update (10.8.2), but it doesn't get better. What can I do?

See this discussion - https://discussions.apple.com/thread/4135250?tstart=0 - many people have had the same problem. One 'solution' that cropped up this morning was to install the combo update of 10.8.2. The poster had updated through Software Update via the App Store with no joy in the battery life, but then downloaded the combo update and battery life was back to normal.
I don't know that this will work for everyone - I just monitor that thread occasionally and saw that post this morning.

How to improve battery performance in mountain lion?

Battery backup time has decreased by more than 1 hour after installing mountain lion. I have a macbook pro 13" early 2011 model.

This is a fairly common issue with macbook pro users who updated to Mountain Lion. Hopefully Apple will fix this in 10.8.1. Unfortunately, there does not seem to be a true fix out there right now.

Extremely short battery life with Mountain Lion?

I recently installed Mac OS X Mountain Lion on my 2009 Unibody MacBook and the battery has been noticably shorter than before on 10.6. Will there be an update to fix this? I don't have any other apps running except Safari. Does anyone know of a way to fix this?

Nobody is ignoring you boovish.
It's just maybe this question has been asked a lot. Have you thoroughly looked through the More Like This box on the right?
That should help you out.

Battery life with mountain lion 10 8 1.. Still awful

After my update from version 10.8 to 10.8.1 , batter life has NOT improved as many have speculated.
I ran the following two tests on a MBP ( mid 2009) 10.8 1 after installing....
-Time to discharge from 100% to 50% remaing - 1h 54 m.
-Time to re-charge to 100% - 2 hr 11 m
I went back and compared these with data gather from ver. 10.8.0. The results were litterally seconds apart. So SOMEWHERE, we've lost about 3HOURS !From OS/x 8 and more from SL 7.6.8 ... ***!!!
What's up with that ? A loss OS 10.8.1 of 3-ish hours?? That's a long time with a full day on campus...
Help !!!

Sorry for the late in responding.
In fact, just today, I sent a note to my contact at Apple informing him that 10.8.2 had not solved my battery problem.
Even after two discharge, charge, cycles, full charge is indicated at 97%, with 1h:04m time available (new 9 mos ago was on the order of 5h.)
In addition, I now have a persistent "service battery" warning flag.
When I hear more from apple, or if I replace the battery, I will report back here.

Re: Battery life in mountain lion

ACTUALLY, the computer is supposed to take a nap during the battery test - otherwise it's not fair.
So after 3 hours, put it to sleep for 3 hours while continuing to count. Then continue with the monitor off. Thus, you arrive at the 'up to 7 hours' number.
If still not 7 hours - then it must be FLASH PLAYER's fault.

It has been noted, yes!

Decreased battery life on mountain lion

Is there an estimated timeline for when the ML battery drain issue will be fixed? I used to get about 5 hours on a charge, and post-ML install, I am now getting 90 minutes max with just word/notes/ical running. I was on a plane and needed to get some work done, but wasn't able to work for more than an hour on a full charge. And the battery is draining significantly in sleep mode. It is down about 40% after being unplugged overnight. This is a serious issue, and impacts my ability to work. I am starting to feel like I have a PC!! (And the woman next to me on the plane who was on a PC got an entire flight of battery charge. Talk about injury on insult!)

Give it 1-2 months.
Until then have you tried this?

How do I get rid of Mountain Lion?

Okay,
so Mountain Lion is (for me) an unmitigated disaster. I loved my MBA11, best laptop I had ever had - because it was rock solid stable, fast and gave me a whole working day on battery.
updated to Mountain Lion, and I have had three hard lock ups this morning (something I had never experienced on a Mac before) requiring a power off reset, and the battery life is unbelievable.
In the time it has taken me to type this, my battery has dropped by 5%. It has taken around 2 hours to drop to 35% - previously, 2 hours of typical usage would have dropped me to about 60%
I don't see *any* activity in activity monitor to suggest that I am getting indexing or so on.
Add to that, that the nice "time left" indicator has been removed for no apparent reason (unless it's been removed because it would show up just how bad the problem is...).
Basically, it's a busted flush. the only thing I want to do now is to get rid of the piece of trash and get my old laptop back... except with no re-install media, and no optical drive on a MBA anyway... how do I get back?

The problem here is that I have bought into the Apple Hype of "it just works". I would never have simply updated a windows PC without a complete backup first, but my experience with the MBA had been so good that I didn't recognise that this update might completely wreck my laptop...
so I don't have a backup of anything except my own data (which is synced to a cloud provider).
I would happily blow this machine away and lose everything on it, if I could just get rid of this blasted mountain lion "virus".

Where is low battery warning in Mountain Lion?

Lion used to give low battery power alerts which I do not find after Mountain lion upgrade. Is it still there or...???

It kicks in at 3% on my 2011 MBA, I have seen reports that the % at which it appears can vary quite a lot, from 16% to 3%.
Speculation would be it depends on the fitnesss of the battery?

My rMBP's battery had fallen to 3% before I noticed it, and I never saw any popup warning. I was not running anything fullscreen (just firefox covering part of the screen).
Running your battery down to these very low charge levels will shorten its life, try to avoid discharging to less than 40%, try to stay on AC power as much as you can (all the time is better than your current useage profile) and only let it discharge when there is no other choice.

How do I print my iCal (Mountain Lion 10.8.5) in 5x7 format?

How do I print my iCal (Mountain Lion 10.8.5) in a 5x7 format? 5x7 is not listed as an option in the print menu.

For custom print sizes, see the software called Clickbooks: http://www.bluesquirrel.com/products/cbmac/
I would ask them if what you want is possible before purchasing. A customer of mine got it to make many other custom formatted pages. Don't have them anymore, but they I'm sure could tell you if it is possible. Be sure to also indicate your printer model.

Forum Mods, Please make this a sticky: BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life

BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life
KB27705
Overview
The BlackBerry PlayBook may come to a power state where it is unable to power on; a Yellow LED may flash in a sequence of 5 flashes, the BlackBerry PlayBook may boot up to the BlackBerry PlayBook Logo and then power off, may not power on at all.
Discharge behavior under normal use:
Under normal active use, a battery drained to 10% will cause the device to prompt the BlackBerry PlayBook user (notification and audible beep)
Without connecting a charger the device will automatically shut down at 3.53V (0%)
Pressing the power button may allow successful boot, but it will turn off again very quickly
Discharge behavior under no use:
A device left unused but in ‘Stand By’ will warn the BlackBerry PlayBook user at 10% (notification and audible beep)
The warning may not be noticed and the device will go back to ‘Stand By’
Letting the device drain in standby mode drains the battery slower, but more completely
Device will still shut off at 3.53V (0%), but it less likely to successfully boot afterwards
Discharge behavior under 3.53V (0%):
If the device is left to shutoff, the battery will continue to drain below 3.53V due to quiescent current draw from the motherboard and the battery fuel gauge
With the battery between 2.7V-3.53V, pressing the power button causes the LED to flash a pattern (1 solid red light followed by 5 yellow blinks) to indicate low battery (PlayBook Tablet OS version 1.0.5, and above)
Below 2.7V there is no activity, or LED pattern displayed
Charge Behaviour:
The provided charger should be used to charge the device. The optional 12 volt rapid charger is may reduce charging times
to approximately 3 to 4 hrs. Standard Blackberry smartphone chargers, other AC adapter USB chargers, or computer USB ports
are not recommended for the sole purpose of charging the PlayBook as with these methods it may take more that 12 hours to
charge the BlackBerry Playbook.
If the battery voltage is below 3.53V(0%) then the charging behaviour is dependent on the software version. The charging code will limit the charging current to under 400 milliamps, during which time, it may take an hour to reach 3.53 Volts. Once the battery voltage rises past 3.53 volts, then "high-rate" charging will start. If, after charging the Tablet for 4 to 6 hours still does not result in LED activity, attempt to force power on the BlackBerry Playbook by pressing and holding only the Power Button for only 20 seconds.
Prior to BlackBerry Tablet OS 1.0.5:
A BlackBerry PlayBook will never charge while powered off in BlackBerry Tablet OS versions prior to 1.0.5.
The device will show a red light when the charger is connected and then nothing more
Repeated connection of the charger can recover the device in some instances.
Once the battery voltage rises above 3.53V the system will boot and the UI will show charging
Starting in BlackBerry Tablet OS 1.0.5:
The device will show a solid red LED, followed by a solid yellow LED as the device boots into charging mode. This is followed by a yellow pulsating LED indicating charging in progress.
The time span between the red and yellow lights can be as long as 45 seconds as the device boots into charging mode.
Once the yellow LED illuminates, the device can be started, but it is advisable to let it charge for at least 3.5 hours to achieve a sufficient charge.
The device will show a solid green LED once the device is fully charged.
Starting in BlackBerry Tablet OS 2.0.1:
Once the yellow LED begins pulsating indicating charging mode, if the BlackBerry PlayBook is disconnected from the charger, the following graphic will be displayed on the screen, indicating charging is not complete, and to reconnect the power source. The graphic will be displayed for 20 seconds before the BlackBerry® PlayBook powers off if the power source is not reconnected. The same graphic will also be displayed if the BlackBerry PlayBook is turned on and there is not sufficient power to perform the boot process.
If the BlackBerry PlayBook is plugged into a power source, and the power button is pressed to power on the device, the following graphic will be displayed if there is not sufficient power to perform the boot process. If this occurs, the BlackBerry PlayBook should be left plugged in to gain enough charge to boot.
Additional Information

With the upgrade to PlayBook OS 2.1.0.1032 the following message may be displayed when connecting the Playbook to a PC using the micro-USB cable:
Unable to charge battery with connected source
This message is displayed because the voltage provided is insufficient for charging. The USB voltage is limited to 384mA even if the maximum tolerance is 500mA. The voltage is limited to 384mA by design to avoid violating the USB specification which states USB devices cannot draw more than 500mA from the USB port.

How do I download Safari for Mountain Lion?

How do I download Safari for Mountain Lion? It's not in the App Store, it is nowhere on the Apple website . . . OK, so I guess it is supposed to be part of Mountain Lion, but I am running Mountain Lion and whatever version of Safari I ended up with would not even run at all . . . so I trashed it (or at least what part of it I was allowed to trash) and though reinstalling it would be a good idea . . . but I can't find one to reinstall. The latest version I can find is for Leopard, and of course that won't run.
Not to mention that since getting Mt Lion, iPhoto won't run . . . it produces an error message saying I need to check with the developer to make sure it runs with this version of OS X! So I wonder who the developer of iPhoto is, who produces software that is incompatible with Mt Lion???
And even in submitting this there is no option to tag it for any OS later than 10.7.4!!

Since Safari is crashing, post a crash report... reinstalling the OS X rarely helps a browser crash issue.
If Safari has just crashed, press the Report button on the CrashReporter dialog box to view the crash information.
Copy/paste the entire contents of the Crash Reporter window into your reply. If the crash report dialog does not appear or the crash is hard to reproduce, crash logs can be retrieved from the ~/Library/Logs/CrashReporter> folder.
Please include the "binary images" section...
