Battery power consumed quickly

* 15" MBP was fully powered.
* I had a couple applications running in the background, but they were all idle.
* Bluetooth was disabled
* Airport was enabled and connected to my hotel's wireless internet.
* Latest software updates applied already
* Energy saver mode was set to "high video performance".
I began to watch an AVI video in full-screen and after about 1 hour, I get the popup window that my battery power is very low! How can that be? Ok, my screen brightness perhaps I have to reduce a bit but come on.. I do not ever hit this problem on a PC laptop. I should be able to play 2, maybe 3 hrs, of video to watch and complete a movie without requiring the power adapter.
Any tips on what I can do?
Much appreciated - thanks.

Sometimes, it happens that the laptop makes the wrong estimates about when the battery is full or empty. The solution for this is to calibrate the battery. Basically, you totally drain the battery overnight. This is described here:

TS1388 My battery on my macbook pro all of a sudden keeps using the battery power really quickly, so I am having to rechareg it constantly. Does anyone know why this occurs or how to fix it. I have used all the energy saving tips.

Hi My battery on my macbook pro keeps running low on power very quickly and I have to keep recharging it. This has never happened before. I have used all the power saver options, but it keeps happening. Can anyone help. The battery seems to be losing power even when it is turned off.

Hi BigThinker,
How old is your Mac? If it is an older one, then the battery may just be dying. You can check by clicking on the Apple in the upper left-hand corner, then clicking on About This Mac>More Info>System Report, then click on Power (about half way down the list). At the top of the resulting display, you should see the following type of info:
The Health Information will tell you if your battery is going to need replacement soon. If it says Normal, then it is not the battery.
Cheers,

Battery power drains quickly

-when i am using vista there are fluctuations in battery power, the battery indicator changes often and doesn't stay on a constant drainage rate (even when i am not opening or closing programs)
-and it takes few hours to fully charge the battery...
-and something really weird happened once, i was using mac os, and i turned off the wireless to save some battery power, but surprisingly, the indicator gave me LESS time for the battery to fully drain.
has anybody had problems like this...

Use powercfg tool from within cmd window (run it with right of Administrator) to check power efficiency.
powercfg -energy
powercfg -devicequery wake_armed

My iPhone 4S runs out of battery power very quickly. I have disabled all functions (ie location services, push notifications etc etc) that actively use power. However, even when in standby mode for most of the day, I'm lucky to get 12 hours out of it.

I read in the press this might be a design fault. Does anyone know how I can resolve this?

There is a huge thread discussing this problem: https://discussions.apple.com/message/16542550. There is a lot of discussion around locations services and the notification centre however many users are experiencing different levels of battery drain and there is no definitive fix at present. You may want to try some of the 'fix' suggestion in those posts and that may help but I would urge to keep an eye on the thread as that is where the majority of the community is focussing and discussing the issue. Also take a look at this recent article:http://www.guardian.co.uk/technology/2011/oct/28/iphone-4s-battery-apple-enginee rs.
I know it's little consolation but there many people experiencing the same problem.

IOS 7 consumes battery power faster?

Hi
It seems like the battery power drain quickly since I changed to iOS 7. I can go to sleep with about 80% battery and when I get to the office it will be around 40%. on iOS 6 I use to loose about 10%-20% power in that 10 hours standby span.
anyone else feels iOS7 uses more battery power?
Cheers

And the wide reports are, like most Internet garbage, wrong. Every time there's an update any problem is assumed to be solely due to that update, with no basis in fact. Try these threads, for example:

Macbook works very slow and consumes a lot of battery power when closed

Hi@all
I hope someone of you can help me. My Mac crashed yesterday. I got a warning saying "there was a problem, your Mac will reboot" (I didn't get the exact words because it vanished quite fast and the MacBook rebooted itself). Since then my Mac is working very slow and freezes every few minutes. I looked at the CPU usage but this is always under 25% so there shouldn't be a programm that causes this problem.
In addition:
When I close it, it seems to go to sleep mode normally but is still consuming quite high amounts of battery power and get's warm. When I work with it the temperature stays normal.
I have a MacBook Pro (mid 2012) with 2.5 GHz Intel Core i5 running with Mavericks.
It would be great if someone has an idea what could cause this kind of problems.
Thanks a lot in advance for your suggestions :-)

sternblume,
for the high energy consumption in sleep mode, you could try resetting its System Management Controller.
For the slow working and freezing, you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the Mac OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode.

Is it normal if an 5th generation iPod Touch consumes battery power very fast?

See, I bought a blue iPod Touch about October in 2012. But then, the battery gets consumed VERY, VERY, VERY FAST! Within 30 minutes, at least half of the battery power gets drained. When i'm charging, it charges fast. PLEASE HELP!!!!!!!

To bobjbkln,
Thank you! I went to Apple today and I ask them if its normal, so then they said that they had a lot of problems like this. He told me a solution which was to first go to Settings, then General, then Reset, then he said to '' Reset All Settings ''. After that, he told me to use all the battery until the iPod completely shuts off. Next, he said to charge the battery ALL the way and that should work. They didn't change or give me a replacement of my iPod.

Artworks consumes more battery power significantly? Maybe a GOOD IDEA!

I'm searching for ways to improve battery power and...
1. Artworks consumes more battery power significantly?
2. If we found a program that equalize (ROCK for example) all mp3 before copy to iPOD, it discards EQ on iPOD to improve power?
Good idea???
Thanks!

significantly?
Very insignificantly... to such a tiny degree that it's not an issue.
2. If we found a program that equalize (ROCK for
example) all mp3 before copy to iPOD, it discards EQ
on iPOD to improve power?
Good idea???
If that's what you want, then I guess it's a good idea. Be aware that raising the eq level also increases the volume. iPods distort extremely easily when the volume going into the amplifier exceeds a certain level.
Once you've run your eq software, be sure to use a piece of software called mp3gain on your files after you do your eq. It will analyze your files and completely losslessly adjust the volume, without even modifying the song bitstream data - magic! This software can handle mp3's by default, and AAC files if you add something else.
http://mp3gain.sourceforge.net/
But before anyone else thinks of running mp3gain on their mp3's or AAC's... DON'T do it for files that have already been imported into iTunes if you use the 'sound check' feature!!!!!!

IPAD 2 loses battery Power Quickly

Problem 1: Within the last few weeks, my Ipad 2 loses battery power even when its powered down I've tried both closing the cover and using the main swithch on the top right. In all cases, I can start out at 100% and within a couple of hours be down to 85% after using it once and either closing the cover or pushing the switch. Its as if something is still running. I looked at the processes with all my apps off and didn't see any surprises . I have processes 9424 dataccessd, 9412 ptpd, 6581 AdSheet~ipad, and 1340 iapd as well as a dozen or so process with numbers in the double digits from 49 on down. It took me 9 hours last night to bring my pad from 20% to 100%.
Problem 2: I recently rented a movie from Itunes and tried to play it through my HDMI interface on my TV using the appropriate apple interface cords. It started to play then I got a message that told me that the device I was trying to play the movie on wasn't authorized for protected media even though I had no trouble playing it on my ipad.?????What's with that?

There is no "4S software".
All iPhones run iOS.
There are dozens of versions of iOS. Which version is your device on?

Battery, Power, Deep Sleep and Spotlight problems after 10.9.4 update

Hi, I have a Macbook Pro 8,1 13in (Late 2011). I updated to the latest version of Mavericks (10.9.4) and iTunes on Sunday, right after that my macbook started to goes into Deep Sleep after closing the lid, even when the battery was 80% of charge. My battery normally lasts for almost 5 hours. After it went to deep sleep, the power bottom does not respond. Also, I have noticed that spotlight process in Monitor was consuming so huge amount of resources. This problem persists in Boot Camp. There is no way to turn the machine up without plugging it to the power cord. Sometimes it charges the battery as usual, sometimes it does not recognize the battery. Suddenly, the mac goes into sleep mode while I'm using it.
I have researching and troubleshooting in order to fix this but no solution. I have reset the PRAM and SMC. I made a backup of my files and installed Mavericks from the ground with external storage in order to erase the entire disk, no solution. I made an Internet Recovery and downgraded it to Lion, it worked for 2 hours and then I upgraded again to Mavericks (10.9.0) and the same problem came again, the upgraded to 10.9.4 and no solution at all.
I have searched on internet and there are other people experiencing this problem but nobody is able to bring a valid solution.
This is my battery's health:

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
Turning off the BlackBerry PlayBook and using standby mode.
Checking the battery power levelOn the status bar, tap the battery icon. When the battery power level is low, the BlackBerry PlayBook tablet will display a notification.
Enter standby modePress the Power button on the top of the BlackBerry PlayBook..
Exit standby modeSwipe down from the top frame to the bottom frame
Turn off the BlackBerry PlayBookPress and hold the Power button. Tap Shut Down.
To extend the BlackBerry PlayBook battery life, charge it regularly, close unused applications and keep the BlackBerry Playbook out of the sun and other hot places. The following may also be used to extend battery life:
Dim the screenOn the status bar, tap the Options icon (a gear), select the Screen tab and change the Brightness setting
Turn off the screen automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Backlight Time-out field
Enter standby mode automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Standby Time-out field
Turn off Wi-Fi when not in useOn the status bar, tap the Wireless icon and set the Wi-Fi switch to Off
Turn off Bluetooth connectivity when not in use
On the status bar, tap the Bluetooth icon and set the Bluetooth switch to Off
Pause apps when you show the home screen or switch between apps On the status bar, tap the Options icon, select the General tab and set the Application Behavior switch to Paused
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.

Satellite L850 - after 1 year of usage battery runs out quickly

Hi, through programs such as care or BatteryBar battery battery I see a Toshiba Satellite L850 *battery wear from 48%* currently. I notice that playing a game the battery runs out quickly, as the warm up by a lot, and often descalibra and behaves erratically.
The laptop is a year old. Is it normal for the battery to wear so much in so little time?
Would you accept a guarantee or battery replacement can claim wear caused by misuse?
http://img690.imageshack.us/img690/6976/4f7k.jpg

First of all you have to know that battery working time depends on the notebook usage.
Running heavy performance applications like a game would discharge the battery much quickly. Why? Because parts like GPU and CPU and cooling modules run at highest performance and this needs power.
Also using the notebook with highest display brightness would discharge the battery faster.
You should also know that every battery would start to loose own performance after about 500 charging cycles. This is nothing unusual and will happen to all batteries.
To avoid or to slow down this process, its recommended to calibrate the battery from time to time.
Calibrating means charging and discharging the battery fully.
Charge the battery until it would be fully charged, then disconnect the AC adaptor and keep the battery discharging until its fully empty. Repeat this procedure 2-3 times in the row.

IPhone 5 battery drains very quickly

I've had an iPhone 5 for about a year and a half and it all of a sudden started draining really quickly. Without using it outside of a few texts, it is at 50% by noon. With use, it easily completely drained by then. Also, I have noticed a few odd things regarding charging my phone: I receive a "this accessory is not meant for this device and may not charge" error and when plugged into my car charger, it alternates between charging and not charging rapidly, just making the battery drain even faster. I replaced the car charger, and no longer have this problem, but recently had the same problem when trying a new external portable charging source. I've stopped using the particular cord that gave me the error, and think this has solved the problem. Just mentioning both these issues as I've never had problems with them before.
Here are the things I've tried to fix the problem:
Tested battery at Apple. First time was deemed okay, the next week they said it was borderline failing (80%).
Replaced the battery by buying a battery online ($25, and relatively well rated). Continued to see problems.
Updated settings (remove location services, switch off bluetooth and wifi, turn off push for all email accounts, you name it I've tried it). Although I tried these things, I did have a phone with all these settings turned on for a year and a half and still had a battery that would last me through the day, so I don't think settings alone are the problem.
Restored phone to factory settings (not to previous iphone back up). This was to address any software bugs that could be causing the problem.
Replaced battery with a second battery bought online (bought the highest rated battery I could find).
Took phone into iPhone repair store. They looked at the inside of the phone and said it looked good. Replaced battery again.
After all of this, my battery still drains super quickly. I do not think it the battery since I've replaced it three times and don't think it is the software since I did a restore to factory settings.
Does anyone have any idea what it could be? I've tried everything I could think of and need to squeeze another 5 months out of this phone until I'm eligible for the upgrade. Right now I have an external battery pack, but this is a bit of a pain to charge and carry around.
A friend of a friend has had some similar issues and they said they had the lightning connector replaced, and it solved the problem. Anyone have any experience with this?
Any advice or help would be greatly appreciated. Thanks!

I have been round and round with Apple "geniuses" trying to resolve battery drainage issues. I have turned off all kinds of background programs, reset the phone and even did a full restore. Nothing worked. The end result was an Apple senior technician just giving up and telling me that the battery life I'm getting is "good." I don't see how that's the case since I used to go to work, use my phone and come home with battery power still in the 70s or 60s if I was really active. Now with most everything turned off, I come home with battery power in the 30s and sometimes even the 20s, just barely hanging on to operational status. I now have to carry my charger around with me and charge this hunk of junk every opportunity I get. The diagnostic on the battery shows it to be fine which is not surprising considering I take very good care of my phone. I had no issues until installing that battery sucking virus known as iOS 8.1. I am so utterly disappointed with Apple that I will never buy any of their junk products again. I am especially angry at being told that the life I'm getting is somehow "good." I imagine that no one actually tested iOS 8.1 before rolling it out. They finished the last line of code and immediately issued it to the public. My interactions with Apple Support confirm that they only care about people who have purchased their latest product. Have an iPhone 5? Too bad! You need to get the iPhone 6 to continue enjoying your Apple experience. Screw their overpriced crap.

Why is my battery draining so quickly after updating to Mavericks?

Why is my battery draining so quickly after updating to Mavericks?

1. Check the cycle count of the battery. It may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.
2. Follow these instructions, or these for OS X 10.9 or later.
3. You can also try resetting the SMC.
4. Make sure your system is up to date in Software Update.
5. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
