How to check battery health..

My battery seems to be having issues.. How do I check the general health of the battery?

I'm in a similar position. I was told about a widget you can download for the dashboard called istat nano.
It gives you a health percentage of the battery as well as other diagnostic details about the mac. The only thing I'm unsure about is how accurate the information it gives you is.

How to increase battery HEALTH

i checked my battery health after installing istat pro today, and it said my battery health was currently at 46%. how can i bring that back up if that's even possible?

The MacBook Power and Battery forum is a better place to ask about this:

Alternative methods for checking battery health

Model: 8922-A26, 3000 C200
So in the process of trying my hardest to keep a recalcetrant C200 from it's sixth visit to the service centre in less than 11 months of ownership, I am trying to see if there's anything I can do to improve its battery life beyond the pitiful 30min i'm currently getting.
Being a longtime thinkpad customer, I tried all the usual methods including the three-cycle power down and drain trick to recondition the battery, with no solution and ran through all the possible solutions in MIGR-63114 to no success at all.
Except one - verify the health of the unit's battery, an online tool which uses ActiveX applets to work some black magic and tell you if it's pooped or not. However, it seems this tool is broken.
It's not working in either IE6 or 7, and despite prompting you to install all the AX components nothing ever happens no matter how long you leave it. And if sitting around isn't good enough for you, you can stare at the broken image which is supposed to be a progress bar.
Does anyone have any alternative ways of checking the battery health on a C200 or firing off some reconditioning tools to save me being another week without this unit? I don't mind dealing with the phone support group, but i'll be darned if I let the service techs near the unit again because I just know my luck will see them fix or replace the wrong part - for the third time in a row.

I don't believe there is a way but more than likely an Apple Store can check it if there is one nearby.
I've seen a post or two here reporting the same and the solution provided (which claimed to help) was using the iPhone until the battery is depleted causing the iPhone to turn off. Plug it in and allow it to charge completely.
And if you haven't already done so, it can't hurt to Reset and/or Restore your iPhone.

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.

How to measure battery health?

My 1-year-old iPad 2 seems to hold significantly less charge than it did when it was new. I know that Apple has a 50% health threshold for warranty service, but is there any way I can see that number without a journey to an Apple Store.

I was prepared to say that the app recommended above wouldn't do the job but after looking .... maybe it will, in the way it approaches things, but I don't think you really need it.
The only way to really know the state of your battery's health is through how it performs in normal use, which is the only spec that is provided by Apple. The test you go through is a multi-stage one, as follows:
Run your battery all the way down, in normal use, all the way until the iPad shuts itself down.
Now re-calibrate your battery metering by plugging it into a known good charging source, for which read the Power Adapter which came with it, and charge it all the way up to 100%. It will take a few minutes before you see and hear your iPad come back to life.
Once it reaches 100%, leave it overnight. The next day, just use it like you normally do, do whatever it is that you normally do; but keep on doing it until the battery goes flat and shuts it down agaion. Make note of how long this took. The average user should expect about ten hours of use out if it, on wifi, less on cellular, depending on how heavy your video loadng is.
The recalibrating needs to be done every month or so to ensure that the metering (the percentage that you read) remains fairly accurate. If you fail to do that, eventually it will no longer be.
If you get less time before it shuts down, try it again. If you consistently get much less time than you should, then you definitely have a battery capacity issue and need to start talking to Apple.

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 check hard drive health

My mac pro starts up and shuts down very slow. Anyone know how to check hard drive health?

Normally if you have a hard drive problem it manifests itself with delays, periodic locks-ups, I/O errors, etc.during notrmal use, not just start ups and slow downs.
Never the less, you asked how you check the health of a drive, so I'll answer.
You can check the SMART status of your drive with Disk Utility or a free tool like smartctl in the smartmontools package. Disk Utility will typically report the SMART status of your drive as "verified" or a message associated with a type of failure right in the Disk Utility window. SMART status will be reported on most internal drives and Thunderbolt drives. More elaborate SMART information can often be obtained with newer OS versions by clicking on the "info" button. SMART is a reporting technology and will only report on errors after they occur. Many in the industry are highly critical of SMART, with a recent study by Google on hard drive problems indicating that it did a poor job indicating impending problems.
Other tools such as Scannerz (http://scsc-online.com/Scannerz.html), TechTool Pro (http://www.micromat.com/products/techtool-pro) and Drive Genius (http://www.prosofteng.com/products/drive_genius.php) do, IMHO, a better job of testing because surface scans can detect errors not detected by SMART yet, and all three of them do those tests. Personally I like Scannerz myself because it's to the point, hardware testing oriented, and can expose other system problems like cable problems, whereas the others are more like swiss army knife tools with a lot of features that may or may not be of use to end users. Some of the people on this site will swear by these tools, whereas others will swear at them. All three of these also monitor SMART status in one way or another.
With software tools out of the way, I'd have to agree with all previous posts, because it doesn't sound like it's probably a hard drive problem. Yes, it possibly could be, it's just that slow start ups and shutdowns are usually caused by too many apps being saved in an "on" state. Any time the system starts, it has to re-load them and resume them as best as it can, and then any time it gets shut down it must save all that information and this all takes time. (I'm assuming Lion or newer operating system is in use). This is often the most likely cause in Lion, Mountain Lion, and Mavericks.
There are other possibilities, but you should probably ellaborate on the problem a bit more.

How to check listed time we charge our battery on macbook air

how to check battery cycle

Under the "Apple" click on "About this Mac: - "More info…" - "System report" - Under "Hardware" click on "Power" and at the top will be your "Battery Information".

HT3782 What does it mean "Battery Health" Check battery in the battery menu bar?

What does it mean "Battery Health" Check battery in the battery menu bar?

Check the full status by going to the apple in the left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about the Cycle count, Battery Condition, Battery Capacisty, charge remaining.
Condition should be Normal or there is a problem
Ratio of charge remaining to cpacity should be close, round off, to the reported battery charge percentage.
Cycle count tells how many charge cycles the battery has been through, typical lifetime cycle count for a current generation battery is 1,000 cycles.

IPod frozen than working... how to check it's health status?

A friend of mine gave me a 20GB classic iPod, it was supposed to be broken, took it home, connected to the usb cable and the icon to get to service it showed up, nothing else to do, no way to access diagnostics, nothing nothing nothing.
Now, connected again to my old Dual MDD it mounted on the desktop and seems to work, what and how do I check its health status?
It would turn very useful for me to have this thing to work so much that I already thought, in case it was the disc, to change it but now how do I get to make sure it doesn't fail again?
Could it be a battery problem?
thanks all for your attention

BTW, I did SMC and PRAM reset and it was the same in Lion when I bought the MBPR. It was working for days until I started noticing disconnect and reconnect iPhone 4S.

How to increase your battery health - anyone with similar experiences?

this is my very own self made instruction of "how to increase your battery health"
it is the procedure how i have done it serverall times on my powerbook g4 12".
my stats: 374 cycles, health 86% (3790 of 4400mAh)
age of my mac: 57month (battery bit newer)
**if you to try this: it is on your own risk!**
**this may not be suitable for mac newbies**
**be sure to read this twice before you do it once!**
you will need:
-a pocket lamp or comparable light (to see anything on your sreen when it is dark --> light from the back through apple logo)
-coconutbattery (coconut-flavour.com/coconutbattery) or comparable programm to track your battery information in realtime
-activity monitor
-cool enviroment (to ensure your fans don't have to work that much)
-some time and patience
the intructions:
step1: load your mac until the orange light turns green
step2: disconnect the power adapter
step3: use your mac until 15-25% battery life (track this information in your menu bar)
step4: slow down your activities. the order of the following actions depend on your usage of your mac:
__close programms that use lots of cpu/gpu to ensure the fans slow down to 0rpm (!!)
__turn off everything that needs battery power: airport / bluetooth / speakers / etc.
__eject dvd or cd
__close all programms with important data
__eject idisk / .dmg files in your finder (this is not only a matter of data security)
__dissonnected from peripherals such as ethernet / internet / mouse / keyboard
__use lower brightness level
__open activity monitor to ensure that your hard drive activity is very low, may be you need to close more active programms, close activity monitor when hard drive activity is very low
__open system preferences >> energy saver preferences >> choose longest battery life
when your are ready with those actions go on and ensure you are able to connect to power adapter with your mac quickly (be able to charge - don't do it yet!)
step5: be patient. now it should take some time until your battery level goes down to 3-5%
now there should be no programm running.
do not open any programm now!
do not have a look at your dashboard!
now your mac should be really quiet:
-no fans (0rpm!)
-nearly no hard drive activity!!
-->> if this not the case break go on with step 11&12, try again in a week or two
-->> if you are ready go on with step6
step6: open coconutbattery und use the lowest brightness level
play with your trackpad to ensure your screensaver won't start. waste time until you are at 1-2% battery life.
step7: take your lamp and spot through the transperent apple logo, position your coconut battery window somehow that you can see the current battery charge und the maxium battery charge in the spot of your lamp through the apple logo.
step8: go from the lowest brightness level to the level under the lowest brightness level (a dark screen)
step9: watch your current battery charge carefully und keep on playing with your trackpad to ensure your screensaver won't start.
step10: there is kind of battery buffer made of approximately 1% (once when my "current battery charge" was 3624mAh and this kind of buffer was at 36mAh)
to empty this kind of battery buffer takes much longer as you might expect!
when your current battery charge turns under this kind of battery buffer, your maximum battery charge should change. hopefully it is higher or stays the same. when it is lower now: i'm sorry - i have warned you. may be you have to go through this 'how to' more carefully!?
step11: plug in your power adapter before the battery is cero!
step12: load until the orange light turns green
step13: if it was helpful do not repeat it more than once a week, better once a month

anyone with similar experiences about increasing battery health!?
(yes, i'm sorry for my poor english, i've tried my best)

Me too! My battery lasts for 10 minutes. It is awful and I am on my 4th power adapter since they keep breaking too.
From coconut battery: Maximum battery charge 310mah, original 4400, age of mac 45 months, 140 cycles.
From system profile:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 310
Remaining Capacity (mAh): 213
Amperage (mA): -1205
Voltage (mV): 11557
Cycle Count: 140
I went to an apple authorized retailer and they said nothing I can do if it is out of warranty.. is this true?

How to turn on Optimized Battery Health Mode

I recently bought a G505 laptop and a popup window tells me I should use the "Optimized Battery Health Mode".
However, nowhere on the popup does it tell me how to do this.
I have searched online and also with the Lenovo Solution Center and find there are all kinds of battery modes
that are spoken of and various ways to access them. However, I cannot find "Optimized Battery Health Mode" anywhere!
I see "Balanced Mode" and "Power Saver Mode" but no "Optimized Battery Health Mode" anywhere.
If I go to the Lenovo Solution center, I cannot find battery settings anywhere under the system tab.
Can anyone tel me how to get my G505 laptop into "Optimized Battery Health Mode"?
Many thanks!

I finally figured it out. If anyone else needs to do this here how I did it.
1) Right click on the battery icon on toolbar, then choose power options
2) From here click on "Change Plan Settings"
3) From here click "Change Advanced Power Settings"
4) This opens up a small window, choose the "Lenovo Energy Management" tab on top
5) Click the "Enable Lenovo Energy Management" button
6) This opens up yet another window with the option for "optimized Battery Health"
Wow, they sure don't make it easy do they?

The battery of my iPhone 5 easily discharges even if not in use. This started 11 months after purchase. The unit passed the Apple Battery Health Test Protocol but the performance showed otherwise. What is the problem and how do I solve it?

The battery of my iPhone 5 easily discharges even when not in use. The unit was tested by Apple and passed the Battery Health Test although the performance showed otherwise. The battery deterioration started 11 months after purchase and is not covered by Apple warranty. What is the problem of the iPhone5 and would appreciate suggestions on how to address this problem. By the way, I have a 2 year old iphone 4S with a battery performance as good as when it was bought two years ago.

Content engine fan gone bad? How to check health?

We deployed a CE-511 to a remote site.
The site contact told me one of the fans may have gone bad cause it sounds like "someone getting a tatoo".
"show power" or "show environment" doesn't work on the content engine.
I can't find anything in the syslog either.
Could someone please tell me how I can check the health / status of the system fans?
thanks.
