Extremely Shortened Battery Life

I just charged my iPod Touch (for maybe the 10th time?). The battery lost power extremely quickly but I wasn't even listening to music or using the iPod. Is there any way to extend the battery life? Thanks

Until Apple implements some sort of "sleep timer" that will shut down/auto sleep the touch, I'm afraid you're stuck with having to turn it off (or at least put to sleep). You can leave feedback to Apple here:
http://www.apple.com/feedback/ipodtouch.html
One thing to note about shutting down the touch (pressing the sleep button for ~5 seconds, then sliding the slider to power off)...this method seems to use more of your battery on the shutdown/power-up cycle then just putting the unit to sleep. I have not tested this extensively but it may be better to just 'sleep' the touch rather than shut it down.
Another thing to check for is if you have WiFi enabled and you have the email application auto-checking for new email, the touch will use more of the battery than if you have this feature disabled.

HT4623 Why is the latest ipad update shortening battery life?

Why is the latest ipad update, 6.1.2, shortening battery life?

The last update 6.1.2 resolved a problem with Microsoft Exchange and could lengthen battery life not shorten it.

If macbook retina gets too hot, can it shorten battery life span ?

hey guys, when I'm gaming on Windows in bootcamp, I'm getting temps upwards of 176 degrees F. Is this normal ? Can it damage the battery life span ? For instance, if battery reads 8 hours on full charge but now it reads 7 hours with same processes running each time

No, that will lenghten its life. Using the MacBook on the battery is what shortens its life.
If you're running Lion your battery will run down much faster than on Snow Leopard. Lion runs in 64 bit all the time where Snow Leopard only ran in 64 bit as needed.

After installing Leopard (10.5) extremely low battery life

Hi, so... I have an original MacBook Pro 15" that would typically get about an hour+ or so use (watching youtube or whatever) or 2+ hours (reading text) pre-Leopard.
Since installing 10.5 I get 20 minutes max. Something is seriously wrong. To prove it here is a screenshot I took after having it unplugged for 2 minutes. The battery is already at 75% and says I have less than a 1/2 hour of life.

I'm a sysadmin for a HigherEd Institution and have always coached my portable mac users on proper battery maintenance (conditioning, checking cycle counts and health, etc...). I've noticed a degradation of the battery in my machine lately, but I just attributed it to normal use and age. I only got this MacBook Pro in April '07 and already these are the stats I'm dealing with:
Battery Information:
Model Information:
Manufacturer: Sony
Device name: ASMB012
Pack Lot Code: 0003
PCB Lot Code: 0000
Firmware Version: 102a
Hardware Revision: 0400
Cell Revision: 0303
Charge Information:
Charge remaining (mAh): 2633
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 3047
Health Information:
Cycle count: 168
Battery health: Fair
Battery Installed: Yes
Amperage (mA): 786
Voltage (mV): 12470
Weekly conditioning doesn't even help it. What's even stranger is that my battery's reported health is all over the place. During any given cycle it can report anywhere from 95% to 55%. Currently, it's holding at the latter. Am I missing something with my management routine, or is Apple just shipping these units with bad batteries? If I can't get better results in the next week, I'm going to have to call Apple. I'm just dreading having to round up all the machines at work to do quality checks on the batteries. I'm dreading even more having to possibly request replacements on them. Ugh...

Shortened battery life after software update to version 10.1.0.4181

I updated my Blackberry software after being notified of the update last week Tuesday ie August 20, 2013. About 30 minutes after the update, I was just using the phone and the phone just shut down even though my battery indicator was showing that I have full battery. I did all to power it back all to no avail until I had to put it on charge that where I say that the battery has drained. But after about 2 minutes of charging the phone came on and the battery is showing that it is full. This has continued since then.
So based on my observation, my battery indicator no longer reflect the true battery status.
Please, I need help on what to do to solve this problem. For now, I don't know when I have full battery or when my battery is going down. I don't think it is wise to alway have the phone pluged on the charger as this I think might affect the battery. But I have had to resort to doing this since last week to avoid the phone shutting down suddenly when I'm in the middle of an important discussion.
I need solution to this problem please.

Hi There,
Have you tried to reload the software? If you have BlackBerry Link you can reload possibly to the older version of the OS, do the update afresh. There might have been some error during the update, also make sure you do the update via wifi.

Re: HTC Rezound update has shortened battery life and causing device to run hot anyone having issues?

budone pointed me in the right direction but I think tidbits pushed him off with apps and clearing cache. Battery app definitely showed me what the issue was.
Battery monitor and phone built in monitor shows phone call usage above 25%. I don't use my phone for hours a day (320 minutes / 4 = 80 minutes talk time). So why is my phone polling Verizon towers so often? Issue also prevented phone from sleeping correctly. So, SIM/firmware conflict. The update pushed a radio setting in the phone to a CDMA + LTE/EvDO auto which was to correct the SIM/reboot issue.
Thread detailing boot loop issue and fix, forum.xda-developers.com/showthread.php
My phone was already set to a correct radio setting prior to the update. When the update was pushed I had my phone in 3G/CMDA to maintain the battery. This update forced a setting and restarted phone and caused a SIM/firmware conflict. Now my phone will go into a boot loop when it drains below 20% and in CDMA(3G). 4G LTE it will run fine. Why? Still attempting to isolate that. I don't think I can unless I have developer access and root the phone. I will not be doing this knowing that there is a manufacturer/carrier defect on my device and they are on the chain for it's repair at the moment. Software, phones firmware agree that it is a CDMA + LTE/EvDO device but SIM has to be removed, phone booted without, TURN OFF, reseat SIM and power on to fix boot loop after charging for a while every day so far. Verizon why am I troubleshooting an issue that your techs should have figured out before pushing a manufacture update? I am paying for Verizon service because it's better than Sprint and AT&T but not cheaper in my area! Where is the Verizon rep with assistance?

Could be something with the new verizon location service that was introduced with the update. So far, I haven't heard exactly what it does, but if it is polling the towers for your location, that could be the issue. Personally, I haven't had any problems since the update, if it wasn't for the extra signal bar, I probably wouldn't even notice. However, the battery over heating is a common problem with the Rezound and, from what I hear, Verizon is being pretty good about replacing batteries for anyone having an issue.

Dropped calls, no service, excessive data usage, extremely low battery life

Ever since downloading the new update all my calls are dropped, I have no service anywhere I never get over three circles anywhere and when making a call it will instantly drop to lower service, my phones battery is quickly drained. my phone has been using excessive amounts of data, even while at home on wifi. I have my cellular data off, back app refresh off, and have taken it into the verizon store they worked on it for a half hour and said it should be good but there is no change. While there I had the rep check coverage for my home, because while I had coverage before I no longer do, he confirmed I should have full coverage 4g Lte, and that I was in an amazing area for coverage. Except I"m not getting any coverage. I've also sat on the phone with verizon several times and had them try to fix it, no help. The circles that show coverage/service will change when I"m not even moving around, for whatever reason. My phone also just generally runs slower and will occasionally freeze up when pressing the home button or closing an app.
I'm sure you'll ask for it so my zip is 53704

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 suddenly reduced

Hi. Beginning a little over a week ago my battery life suddenly reduced by about half. My iPhone is warmer now, even when it's not in use. It wasn't coincident with anything I noticed, e.g. no new iOS release, no change in application use. I've reviewed my Location Services, no unexpected grey GPS symbols (and no purple of course). Does anyone have any ideas as to what might cause this?

Lots of people have lots of ideas:

How to maintain a macbook pro mid 2012's battery life

Hello,
I know that there are a lot of past posts of this, but they still leave me unanswered. Being a recent windows user, I don't know everything there is to know about macs, however the one thing I do know is how expensive they are, so I want to keep everything in tact for as long as possible.
One of the key things I have realised from these discussions is that people are saying it's bad to leave a mac charging, it's bad to fully decharge a mac, and it also seems alright to not charge it fully or decharge it fully before charging. These were all kind of confusing to me as I thought to keep a battery healthy, you had to completelly drain it before charging it, charge it fully whenever you charge it, and it didn't hurt to keep it charging constantly.
Now for anyone who doesn't want to read all thet above, the key things I want to know are:
How to keep the battery healthy
Will fully decharging it affect it
What happens if I don't fully decharge before charging/ what happens if I don't charge it all the way
What happens if I leave it charging constantly
And if I am charging it on and off at school, what will happen (i.e. one period I charge it 20%, then unplug it and then charge it another 20% the next period)
Thanks for all your answers in advance, and cheers for reading all this. I hope you can clear me up .

FALSE information. You may leave your MBP attached to the charger as much as you want. It cannot over charge. Avoid draining the battery completely. That will shorten battery life.
I keep mine charging all the time but about one per mont will use it with just the batter yo about the 40% charge level.
And if I am charging it on and off at school, what will happen (i.e. one period I charge it 20%, then unplug it and then charge it another 20% the next period)
You sometimes have to deal with realities. When Ac is available, use it, but it will not be so at all time. It will not have a great adverse affect on the battery.
Here are some articles that you should read that will fill in the details:

I have the 13" Late 2011 Macbook Pro, What are the best Battery Life saver/increaser Techniques?

Specs-
2.4 Ghz Intel Core i5
4GB 1333 MHz DDR3
intel HD 3000 384 MB
How can I prevent My battery from degrading or atleast make the degrading slower
Can Ya tell me the steps or things to do?
I use my Mac a lot, like 6-15 hours everyday.
Someone told me I should keep it plugged with decharging it fully once a week.
is it true?
Can anything else be done?

You can use it on battery almost full time. It will slowly discharge to about 95% on AC, but then recharge after dropping below 95%. This is to save the use of the recharge circuits.
You should use it on battery only down to 40% at least once per month. Running it to dead will shorten battery life, not help.
The battery is rated to 1000 cycles. Two recharges from 50% to full is 1 cycle, 3 recharges from 33% to 100% is 1 cycle, etc ...
If you plan to store it unused for 3 months, discharge the batery to 50%, then remove from the MBP to preent the battery going down to 0.

MacBook Pro Snow Leopard battery life

Okay, I've been poring through the threads for days now to try to find a solution to this . . .
I have two different MacBook Pros (a 15" 4,1 and and a 17" 1,2). I've upgraded both to Snow Leopard. Each is now running 10.6.6.
After uprading, both started suffering extremely poor battery life, losing nearly 1% each minute, even when the Mac is sitting and doing nothing.
I've done all the fixes I've found (recalibrating the battery, resetting PRAM, checking for rogue processes, etc.), and so far nothing has fixed the problem. I even bought a new battery for the older Mac, and that had absolutely no effect.
Some of the threads I've seen here go back for more than two years.
Has anyone solved this problem? I'm at the end of my rope!

1% a minute?
You're quite right - this problem has existed for years. Apple bases its power estimates on a device half intensity, using Energy Saver, and SL is supposed to have better battery performance than Lion.
Something is causing your battery to die on you. Check off the following one by one to make sure there isn't another problem:
1. Are you attached by USB? If you leave your MBP attached to a USB device or Firewire cable, you can lose battery power even if your computer sleeps. Disconnect all devices when you're not using them.
2. Are you using Energy Saver? Your machine may be sapping energy by being at high intensity. Instead, opt for a monitor at half or three-quarters brightness.
3. Losing battery even while sleeping? That problem can be addressed by going to System Preferences/Bluetooth and disabling Bluetooth.
4. Are you losing battery through heat? You can lose battery capacity with a system that's hot all the time. Keep your machines as cool as possible, through energy management, getting a laptop cooler, or using free applications like Fan Control.
5. Limit your losses. Use a power cord whenever convenient to increase your real-life battery time.
6. Some applications, like Skype that are on all day, sap battery power. If one such application is on all day (or close to it), this may be part of the issue.
7. Don't upgrade to Lion. This OS demands twice as much power as SL.
I don't want to minimize the significance of the issue, but take a look at which processes are drawing power. You might want to go to Utilities/Activity Monitor at take a look at which applications are consuming your CPU.

N80 v5 firmware and dire battery life

Updated to the v5 firmware for the N80 (5.0719.0.2) and apart from the annoying loud warning tones, the biggest problem I have with this is the extremely short battery life now.
Charged last night, left on standby for maybe 10 hours, and the thing is flat in the morning!
I doubt the battery has suddenly died. Before updating to v5, the phone would last several days on standby.
I can't see that it is connecting to any access points during the night. Bluetooth is off. WLAN scanning is off.
I know the N80 is old now, but anyone found a solution to this or have some tips?
Only other thing I can think of doing is a total reset of phone and media memory, and reinstall everything from scratch.
E72-1 UK CV 052.005

I have had V5 on my N80 a year or more now and there is definitely no reduction in battery life.
Make sure that things you don't normally use like 3G, bluetooth and wlan scanning is switched off. If this doesn't work then try resetting and failing that, reinstall V5.

Is my battery life gone? R.I.P

I have used my ibook G4 for 1year and 3 month already, but now the battery suddenly showing some strange loss of its battery life, it takes only around 50 minutes for full charge, and after that only around 45 minute i can use before it drains out,
usually when the battery drains out, my ibook will go to sleep mode and it will maintain the sleep mode as long as i want it to be, but now what suprise me, when the battery drains out, it will suddenly turn off my computer instead going to sleep mode, it have happen twice now, so thats what makes me very worried, im so frustrated because i take care the battery so well but it suddenly become like this, not in a degrading fashion, its all in a sudden...since 2 days ago...
first question of all, is my battery life altered? or my battery already dying? what should i do? change to new battery? the new battery is so expensive...
2nd question, will my computer be damaged if it suddenly turn off like that without shutting it down properly?
hope somebody can help me on this

Welcome to Discussions!
Yes, if your iBook is not going in to "sleep mode", and abruptly turning off, it can cause damage over time. You said that is "fully charged" after 50min. Try leaving it plugged in for a full 24 hours, and see if that extends battery life at all.
Question? Are you running any processer intensive applications when its on the battery? Anything such as an audio/video application, anything with mathmatiacal equations, playing games, using the CD ROM drive, ect... All of those factors can shorten battery life. When the iBook runs out of power, it should automatically go to sleep, and remain in sleep for a day or two before finally shutting off.
Try resetting the PMU (Power Management Unit) ((taken from the Apple Support website))
1. If the computer is on, turn it off.
Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
Wait 5 seconds.
Press the Power button to restart the iBook computer.
Reset the PRAM:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Reset the NVRAM:
1. Turn on your iBook
2. Before the grey screen, press command-option-O (letter)-F
((O is for "open", and F is for "firmware"))
3. You will be at a grey screen displaying some information.
4. At the Prompt, type "reset-nvram" press return.
5. Type "reset-all" press return
6. Type "mac-boot" press return
I hope this helps!
Best,

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?
