How to check battery life

I'm trying to check my battery life on my nano and I read the instructions given by apple (http://docs.info.apple.com/article.html?artnum=61475), but i am still confused on a couple of things. First, I wonder whether or not I have to have my earphones plugged in during the test, and secondly what volume to test it at.
Thanks!

I'd keep the headphones in, but you don't have to. Put the volume at around 50%.

How to save battery life on iPod touch 5g?

Give me tips on how to save battery life on iPod touch 5g.It dies out very quickly.

Turn down the screen brightness
Look into notifications. it defaults to everything being on and you can turn off most if not all of them.
Check your e-mail. If it's on push that means it's reaching out for new mails every so often, turning it to fetch means that it only goes to get mail when you tell it to.
Look at some of your apps. Some of them may be doing things in the background that you don't realize and you can tweak those to not run when you don't need them to run.

Any tips on how to improve battery life on new macbook pro?

Any tips on how to improve battery life on new macbook pro?

It all depends on how much you plan to run on battery power. If you don't use it often, set yourself a reminder to let it run unplugged about every couple of weeks to aboout a 40% charge and then plug it up and let it charge back to 100%. If you'r'e a frequent battery user (like me) don't let your MBP discharge to the point where you're running on reserve power - down to about 30 minutes remaining and then charge it back in.
I have over 130 cycles on my computer and I've just had it since March. Even though my battery health was 102.2% when I got my MBP, it's still at 98.8% health and I'm still getting 7+ hours out of my battery. To get the longest use when under battery, keep your activities to low-CPU intensive apps (browser, email client, word processor, etc.) - Internet surfing alone, and not watching a lot of online videos, will give you mor ebang for the buck. You can also check your battery health in 'real time' by using "Battery Health" - free from the App Store and you can make sure that you're running on integrated graphics, which uses less power, by downloading Cody Krieger's exceptional gfxCardStatus.
Keep your screen brightness down to about four ticks and your keyboard backlighting to one tick - should work fine.
Good battery health to you,

How to preserve battery life ~ used to last all day, now it runs out by lunchtime

How to preserve battery life ~ used to last all day, now it runs out by lunchtime

I would advise updating to iOS 7. It might improve your battery and the bugs are worked out by now.
If not wanting to update because of the new look, here are some tips:
-Turn off bluetooth when not needed.
-Connect to wifi and turn off cellular data when possible.
-When not around wifi, turn wifi off.
-Keep your screen at around 50% brightness.
-Disbale certain apps or features in Settings<Privacy<Location Services if they are not necessary.
-Close out of apps in the multitasking bar.
-Enable airplane mode when you plan on not using your phone for a while.
Hopefully these tips help you. If your battery does eventually get too bad, you can get it changed out by apple. If youve had your device for under a year, you can take it into an Apple store and theyll give you a new phone in return. Have a good night and good luck!

3GS Upgraded to OS 3.1.2, How is your battery life now?

I upgraded to 3.1 only to find my battery life halved to around 4-6 hrs depending on use.
I then upgraded to 3.1.2 hoping this would be fixed, but no luck.
I use this for work but it wont even last 1 8hr business day without a charge.... not impressed!
How is your battery life since upgrading to 3.1.2?
Is Apple working on fixing this some time soon, or do I start looking for a new "non-iPhone" phone?

My battery life has been just fine with all OS versions; no change with 3.1.2

Many of us have no problems with battery life. So I'm not sure there's anything general for Apple to fix -- but your iPhone may need attention. Why not take it to to a Genius Bar?

How is your battery life? (on new ZEN on

Well, after the firmware update I thought I'd give it a try and see how long it would last.Last time I did this I got 22 hours, with the first update, the sd card one. This time it ran for 28 hours! With volume 5/25, when I did my last test with 22 hours, I only had it at 5/25 volume.No EQ, no smart?volume, no bass boost etc...And most of my music is 96 kps wma or 28 kps mp3 with a few 92 kps mp3s I've downloaded recently. Then while I'm doing?the test, I'm looking at the Zen page to see how they got battery life(sometimes they say half volume at 28 kps mp3 etc) and I noticed they upped it to 30 hours life instead of 25!Now I don't feel so special. :P?So, I just want to know how much juice you get out of your ZEN?And say if you use eq, volume level, bass boost, kps, etc

Hi guys, you will not keep your player on all day long, so you will not get those?playback durations in normal daily use... i tried all the f/w and now i?use my zen?with the .03.04 f/w and it gives me about 4-5 hours (EQ on, Bass Boost and Smart Volume off and i browse the player much)... yesterday, after an approximately 3 days of daily use (4-5 hrs/day) it got down to the final bar... This is better?than the new f/w?s?for me because when I turn it off with the new f/w s it drains quickly because of the hot standby mode... if you have any solutions for this issue (except leaving it turned on ) i will update my f/w too... coz i can not use my SD card as well as i want to especially while watching video...

How to check battery level?

Is there a way to check the battery level on the iPod Touch? I recently acquired a new 32 GB Touch, and the first thing I did was upgrade to the 2.0 software. I have been unable to find an option or menu that will tell me how much battery life I have remaining.
In looking around I was able to find that on the iPhone there's a Settings > General > Usage menu, but I don't have that on my Touch.
All I ever get is the 20% remaining warning message. Is there no other way to determine how the battery is doing?
Thanks for the help...
-Gary

Hard to believe they don't have something that tells you where you're at. The icon is okay, but is not as helpful as an approximate percentage or number of minutes remaining. I realize battery life remaining can change drastically, say if you start watching a movie, but it would be nice to have something a little more substantial.
I submitted feedback...thanks for the link.

Check battery life

I have two ibook G4 batteries and was wondering how I would go about checking to see which has the better life, or in other words, which holds the better charge.
I am selling one of my two ibooks but I have been using both and would like to keep the better of the two ^_~ so I am just trying to figure it out...the values on the computer are off so much I don't really trust them

Search for Coconut Battery on Google. Download, and run the software. It will give you very detailed diagnostics on your battery, beyond system profiler and iStatPro. You will probably want to calibrate the batteries before running the software. To calibrate, fully charge the battery, then run the machine until the battery life causes the computer to shut down. Follow this with another full charge and the battery should be calibrated. After the calibration is the best time to assess battery life.

How to save battery life (ipad mini)

When I'm away from home and I don't have my charger. What are some ways that will save my battery life? I know the basics like screen brightness and double tapping the home button to delete history. Are there more ways I can save lots of battery life?

See some of the links below.
Could be the charger, cable or iPad. Plug the USB cable into your computer. It may say "Not Charging", however, it is charging slowly and will verify that the cable is good.
Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

How to expand battery life with iOS5 on iPhone 3GS, it's shorter than before?

I upgraded to iOS 5 and since then the battery doesn't seem to last that long any more. Are there any settings I could change to improve that?

Just as a heads up -- I've been out all day for the last two days with my 3G without recharging, and I still have a half-full charge at the end of the day with bluetooth on (though not paired all the time) with Wi-Fi on, and with three or four hours of internet and music usage a day. I don't fetch data, but have it set to check e-mail every 15 minutes. And it has been on 3G the entire time...it doesn't run down as fast as some people might think -- in fact, it is a lot longer battery life than any other 3G phone I have owned from ATT.

How to save battery life for ios 7

How do you save battery life

There is many things to help save battery life on IOS, hear are some battery saving tips I use when with low battery .
Battery saver 1: Turn off Bluetooth , by going to "Settings>Bluetooth" and switching the little "On/Off" toggle.
Battery saver 2: Turn down the screen brightness half way or just below is fine, for at home, but if you use your idevice outside turn it up just below max brightness so you can see the screen, to turn up or down brightness you can navigate to "Settings>Wallpaper and Brightness" and there will be a slider to adjust brightness.Or if you are on IOS 7 you can swipe up from the bottom of the screen and it will bring up "Action Centre" and there will be a little sun icon, next to it will be another brightness slider, to exit "Action Centre" press the home button or just swipe the little down arrow.
Battery saver 3: Volume turn the volume up and down at certain times of day "eg: I turn volume up full or just below in the afternoons because most things are going on in the afternoon that probably make lots of noise, and at night turn it down because your ears have adjusted to quietness and can pickup on quieter sounds".
Battery saver 4: Turn off WIFI when not in use "eg when playing games or just switched off" you can do this by going to "Settings>WIFI" there will be a "On/Off" toggle or via "Action Centre" "IOS 7+".
Battery saver 5: When your not going to be using your device for a while shut it down by holding the "Sleep/Wake" button.
Battery saver 6: Close apps running in the background by double tapping the home button and holding down the running apps then tap the little "-" minus in a red circle to close "IOS 6 and lower", things are a little different with IOS 7 its the same process of double tapping the home button but a different way to execute the apps, you do this by swiping "Up" on the open apps. "Tip: You can swipe 3 at once!".

How to prolong battery life

How often should i calibrate the battery? does calibrating the battery more often help to prolong battery life? I usually leave airport on even if im not using the internet, so does that drain the battery life much faster than if I left it off? I use my laptop sometimes in class with airport on, but im not using the internet. And it went from 100% to about 85% in about 40 minutes. Text edit was the only application I had open. is this normal? Idk i might be wrong, but it just seems to me that my battery drains really fast. bluetooth is always off. at home even when its at 100% i leave the charger plugged in. is that affecting battery life?

How to calibrate:
http://docs.info.apple.com/article.html?artnum=86284
Do that for a couple of month or whenever you think the battery starting to behave erratically.
Some more explanation :
http://www.apple.com/batteries/notebooks.html
And 15% for 40 minutes is about right even if you using it only for text edit, considering the screen is on most of the time.
Yes airport consume power too, if you not need that for a long time (in class for 1 hour), turn it off. But some user posted that the different is only couple minutes only.
And new battery technology won't let you over charge the battery, so it still safe to leave it plugged let say overnight.
Good Luck.
