How to properly drain & calibrate the battery?

I have a dual-usb ibook g3 (500Mhz), and I'm trying to fully drain the battery to calibrate it (right now it runs for about 10 minutes before giving a low-battery warning). I ran the laptop until it forced itself into sleep mode - now, it's been sleeping for about 5 days! Is there a way to get it to drain all the way faster?? Thank you.

As I understand it, most iBook batteries were not subject to "battery memory" as the symptom was sometimes referred.
I'm guessing your iBook G3 and the included battery have more than a few charge cycles and the battery may simply be at the end of its life.
Replacement batteries are somewhat expensive but may be your only option for running your iBook off of AC Power...

Save and Protect your iPad Device: How to Save and Prolong the battery life of your new ipad

Please, as you read add more answers to this on how to prolong and save your ipad battery life. Thank you
Saving the battery life of your iPad
1.Keep Your iDevice Out of the Sun
Whatever you do, don’t leave your iPhone or iPod sitting in a hot car—heat kills batteries faster than any other factor, and your device that used to keep a charge for hours will eventually barely hold a charge, and you’ll have to pay Apple to get it replaced. The same thing holds true for any really hot environment: try and store your device in a cool place.
Reduce the Screen Brightness
If you keep the screen at maximum brightness all the time, you’re wasting a lot of battery life—and the screens these days are so bright anyway that you don’t really need to, especially at night. Head into Settings -> Brightness & Wallpaper to adjust the default level of brightness, which you can probably keep as low as 30% most of the time.
2. Make Sure the Screen Locks Quickly
Even if you’ve adjusted the screen brightness, there’s still no substitute for having it turn off quickly when you’re not using it. Head into General -> Auto-Lock to set the screen lock to happen as quickly as your device will let you. This makes a big difference if you are always picking up your phone and putting it back into your pocket without turning the display off.
3. Use Airplane Mode When You Don’t Need Internet (iPad/iPhone)
If you’re busy spending the next 8 hours playing Angry Birds, there might not be a good reason to have internet access, so you can consider using Airplane Mode, which turns off both Wi-Fi and the regular wireless radio. Of course, this will prevent phone calls if you’re on an iPhone—but if you’re busy with Angry Birds you probably don’t want the interruption anyway.
4. The more important reason to use Airplane Mode is when you’re mobile in an area with a really spotty connection—because the iPhone or iPad will try to stay connected at all times, it’s going to be constantly searching for a connection, which can drain your battery. Head into Settings and flip the Airplane Mode switch right up at the top of the screen.
Use Wi-Fi Instead of 3G if Possible
According to Apple, the iPad will get 10 hours of battery life under regular use with Wi-Fi enabled, but will only get 9 hours using 3G—the iPhone gets 6 for 3G and 10 for Wi-Fi. Of course, if you’re heavily using the Wi-Fi, you’ll still be draining the battery—the point is under similar workloads, Wi-Fi is better than 3G for battery life.
You can enable Wi-Fi under Settings -> Wi-Fi, and then pick the network you’d like to connect to.
5. Reduce or Eliminate Mail & Calendar Checking
If you’ve got a bunch of email, calendar, or contact accounts configured, and they are all being checked and downloading email on a regular basis, you’ll be draining the battery an awful lot faster than you need to.
Head into Settings -> Mail, Contacts, Calendars -> Fetch New Data and change the setting to the least frequent check possible. If you don’t use it often, you can just turn Push off entirely and then manually check when you need to.
6. Reduce or Eliminate Push Notifications
Do you really need notifications from Twitter or whatever other apps you’re running? You can turn these off one-by-one, or turn off Push entirely by heading into Settings -> Notifications, and save a bit of extra battery life since your device won’t be pulling in data for those applications anymore.
7. Reduce or Eliminate System Sounds
This one is probably a little silly, but if you really don’t care for the system sounds you can save a small amount of battery life by removing the sounds. A very, very small amount, most likely. Head into Settings -> General -> Sounds to change them.
8. Disable Location Services
If you don’t really need the location services, you can disable them to save some battery life. Head into Settings -> General and flip the Location Services setting to off.
9. Disable Bluetooth If You Don’t Need It
If you don’t use a Bluetooth headset or keyboard, you should keep the Bluetooth radio disabled to save some extra battery life. Head into Settings -> General -> Bluetooth to flip it on or off.
10. Disable Vibrate Feature in Games
If you’ve got a game that uses the vibrate feature, you can turn that off to save some battery life. This mostly matters if the game heavily uses it, and you’ll need to change the setting for the game. As a side note, and it should go without saying, if you’re running really intensive video games, they will kill your battery very quickly.
11. Charge and Discharge Your Battery Regularly
Your iDevice needs to be fully discharged and recharged at least once a month to operate at maximum efficiency and keep the battery from dying. You’ll also want to make sure that you don’t store the device with a dead battery, as that can also cause the battery to lose charge capability—when your battery dies, make sure to recharge it quickly.

The reason that Apple suggests you drain and recharge your battery once a month is not because it affects the life ofthe battery. What it actually does is calibrate the battery sensor, giving you a more accurate reading.
Other than that, you done an admirable job of summarizing the Knowledge Base article:

Hi i received the nano 7th gen for Christmas and I only seem to get 5 hours of battery life. I use the Bluetooth and Nike app so I expect more drain on the battery. But I got more time out of running with my iPhone. Does this sound normal? I thought I should get close to 30 hrs of just play time alone.
ALso, my wife got me the Belkin armband to run with the nano but I sweat through the band resulting in the back of the iPod to get wet. Surely this is not good. Anyone have a recommendation for an armband that keeps moisture away from the pod?

iPod Nano are small and they don't use Wi-Fi access so you get less power time on a Nano. As for iPhone, since you got apps, Wi-Fi + 3G access, and everything else, they give you more time so you can keep using. Nanos are ment to listen to music, listen to radio, view your photos, watch videos (without Wi-Fi) and since you got BlueTooth on the nano, it counts as wireless access so it drains your battery faster.

You should perform this procedure when you first use your computer? is this true? new macbook pro on may 11 2010 what happed was today on may 22 2010 i wanted to calibrate the battery my new macbook pro turns off when it runs out of battery. 3 times Typically, when macs run out of battery, they go into sleep mode. However mine skips this completely and just turns off. WHY? does this mean the battery is bad?
Resetting the PRAM (http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html) fixed the problem in my case. then i did the calibrate the battery again this time it went to sleep not shut down i did this 3 more times why?
the 3 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010

the 9 more 4 in 10.6.4 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010 but if it happens again you should try

How do I best replace the battery latch in a HP Probook 4510s?

How do I best replace the battery latch in a HP Probook 4510s? After letting it fall, I had to replace the battery latches.

Hi:
Please review the notebook tour guide at the link below. See page 9 for the bottom components illustration.
http://h10032.www1.hp.com/ctg/Manual/c01849861.pdf
There is a battery release latch on the bottom of the notebook. When you remove the battery there should be a part number on it on a white tag. The part number would be arranged 6 digits a dash, and 3 digits (123456-001).
Then you can input the part number at the HP parts store at the link below. You may need to change the country location at the top. I have it set for the United States.

How to properly back up the iPhone (I clearly did it wrong)

I backed up my iPhone, named it and then restored it to the factory settings. When I went back and right clicked on the phone to "restore from backup", the backup I had just made was not there. Only a backup from September. Now, I've lost everything since September, that was on my phone. I was wondering what I did wrong and how to properly back up the iPhone for future reference. Does it only save 2 backups? I just am not sure why it didn't save my most recent backup, and rather, saved one from September. Sad, I lost a lot of important texts, numbers, notes and pictures. Thanks for any help!

Why the iPhone 4 16GB drains out the battery faster after upgrading to ios 5?

Why the iPhone 4 16GB drains out the battery faster after upgrading to ios 5?

Not sure, but try this:
Let the battery drain to below 20% (I went to about 14%).
Plug your phone in and leave it to charge COMPLETELY. This took my phone somewhere around 4 hours to complete.
When you're done, you may have better luck keeping a charge.
iOS 5 adds a lot of additional communication, and every time you connect wirelessly to anything, more power is used. Even so, some people report that a battery cycle like this helps. It seems to have worked for me.

How do you know if the battery is completely dead?

I'm pretty sure that my iPod Shuffle's battery is completely dead. Even though I charged it longer than the alotted time there's no charge and the indicator light doesn't come on.
How can I replace the battery?

If the battery check light shows nothing, and the front status light is similarly dead, then you can assume no power. That could certainly mean a dead battery.
The battery is not a user-replaceable item. Apple's official solution is provided through the battery replacement program, which you can find discussed and described on the iPod Shuffle Support Page and elsewhere.
I think you'll find the price delta between that and simply buying a refurb isn't that great. Something else to keep in mind is that that's what you're doing anyway; you don't get your own machine back.
You can open the Shuffle up and try replacing it yourself, if you like. It will involve some fine work and some soldering, but some have claimed success. There are now sources for the batteries themselves. Guidance for all of that can be found online.

Do I still need to calibrate the battery every few months?

Hi, I recently bought the MBP 13" i5 and I read on a forum that MBPs made mid-2010 or later come precalibrated
and "do not require the calibration procedure outlined in this article."

Should I still calibrate the built-in battery every one or two months to maintain battery life?

I would follow Apple's recommendations.

How to properly use iphone 5s battery performance

Will my iphone 5s battery performance still be at maximum (full performance and capacity) if I charge it at any percent like 57%? I always thought charging it any time will weaken the battery life so i'll have to charge it more frequently as time goes by.
Also, is charging my iphone 5s in the car and/or through a computer the same thing as charging through an outlet?

No. The iPhone wall adapter supplies 1 amp. Most computers and built-in car usb ports only supply 1/2 amp. So it will take twice as long to charge using those. And, if the iPhone is actively being used (such as using it as a GPS in a car) it won't charge at all, because the battery will be draining as fast as it is charging.
You can get higher current adapters for cars (I just got an InCase 2.4 amp car adapter yesterday at an Apple store), and some newer computers can supply 1 amp (including all Macs since 2011). There is no iPhone benefit to an adapter that supplies more than 1 amp because the charging circuit in the phone limits the charge rate to 5 watts (1 amp @ 5 volts). An iPad, however, can use up to 2.1 amps (12 watts).

Nokia 2610-How do I know if the battery is fully c...

Just got a Nokia 2610 phone.
Plugged the charger in, and it's charging, but how do I know if it's fully charged?
The battery symbol is still empty, but there are lines going up/down the screen (like a battery/or reception symbol)
Is there any indication that the phone is fully charged with the 2610? Or how long should I charge it for..etc.
Anyone info, or insight would be great, Thanks!

Since reconnecting bluetooth on my 3G after accidently dropping (the ap not the phone) I have successfully reconnected only to find the phone continuously searching for devices. To stop excessive draining of the battery I turn bluetooth off.

After successfully reconnecting my 3G iPhone to bluetooth (I accidently dropped bluetooth) the phone contantly searches for devices. Everything works fine now but it appears the battery is draining more rappidly because the phone is constantly searching in the background. I turn bluetooth off when I exit the but it drives me nutty. Any suggestions?

Is it possible to find out what serial or UDID info is stored on iCloud being used by the FindMyIphone site? The FMI website doesn't show anything but the name and the device image (which is a generic iPhone image, and definitely not the 5S )
Unfortunately not.
