Calibrating a used Battery

Hi you guys.
I bought this used ibook less than a year ago. I have been using it for a while. When I fisrt bought it the battery would last for four to five hours. I know you are going to tell me that they only last for year or so but this one has been used for more than two years and stills get good juice out of it.
I was wondering if it is possible to calibrate it again to install tiger. I have been running Jaguar on it all this time and I my guessing is that tiger would give me half of the half I use it for regularly or it would completely drain it for the first 30 minutes.
Recently the battery only gets to be at 65% percent and then it goes to sleep. I will problably need to buy a new battery for a new operating system but in the mean time I am still deciding to buy a new ibook and keep using what this incredible ibook gives me for the moment.
Would it be worthing to calibrate it again? and if so. How could I calibrate a battery that only goes to 65%?
ibook G3 800 MHZ Mac OS X (10.2.x) 640 MB of Ram
ibook G3 Mac OS X (10.2.x)

Apple recommends calibrating the battery once a month:

Best Practice to use battery

Sir, I am a Lenovo user since 7 months, I have a technical doubt . Is it good to run on battery power or to use a charger when I use it in my home? Please tell me how to use my laptop efficiently . Is it good to running on AC adapter or on battery for 1 or 2 hours of usage
Please advice
Solved!

Hi
Capacity is the length of time you can run your system on a fully charged battery. It is normal for all
batteries to lose some capacity over time. Each time you discharge and recharge your battery, you will lose
a very small amount of this capacity.
Some of the capacity may be recovered through using a more aggressive power management scheme.
You may also want to check for specific information on your system; for example, some BIOS updates
include power management enhancements. Other systems have specific tools to help with battery life.
You can charge the battery pack while the computer is powered on or off.
After the battery pack has been fully charged, you can operate the computer;
however, the battery gauge may not accurately report the amount of charge until
the battery pack has been calibrated. It is, therefore, recommended that a new
battery pack be calibrated soon after purchase.
To maintain the measurement
accuracy, Lenovo recommends periodic calibration about every 90 days to reassess
the energy storing capacity of the cells. To complete the calibration of a battery, a
full charge of the battery must be followed by a full uninterrupted discharge.
Unless these two steps are completed together, proper calibration is not achieved
Hope This Helps
Cheers!!!

IPhone 6 Motion Calibration Always Using Location Services

hi
just received my iphone6 and is updated to ios8.
IVe noticed that the location services was constantly on so went through each item which was enabled for location sharing and disabled one by one. I discovered that under Privacy > Location Services > System Services > Motion calibration was purple. As soon as I disabled it location sharing icon switched off. As soon as i enabled it it came back on again and the purple icon showed up next to motion calibration meaning it was in use.
So my question....what is motion calibration and why is it constantly using location services??
thanks

yes i have the same question, new iphone 6, restored from icloud back-up from my iphone 5, and motion calibration is using location services very frequently. it doesn't appear to be draining my battery to badly, but id just like to know exactly what its doing so i can know whether or not i want to keep it on. turning it off until i know exactly whats its doing.

Using battery while charging

Pretty much the headline.
When im using my Macbook Pro 15" late 2011, for gaming, its using battery while the charger is pluged in.

If your charger is working right, it is NOT using your battery while gaming and connected to the charger.
As for gaming on battery:
You shouldnt do that a LOT because it causes RAPID discharge of the battery
See 3B below::
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
Do not perform “battery calibration” on your current Macbook. There is no calibration of current Apple portable Macbooks with built-in batteries.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

HT201263 When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds. While in auto-lock it is using battery power and will do so until the battery is drained. Whats wrong

When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds. While in auto-lock it is using battery power and will do so until the battery is drained. Whats wrong?

- Try a reset. Nothing is lost:
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Connect the iPod to your computer and try to restore via iTunes. Try placing in Recovery mode if necessary to restore.
- If you can't turn the iPod completely off, let the batter fully drain. After charging for at lerast anhour try again
- If still not successful time for an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

My iphone is currently using battery life much more quickly than inthe past, and it also has an icon tht is starying on the screen, to the left of the battery charge percentage, that looks like a lock with a circle around it

i have an iphone that is using battery life much more quickly than in the past, a full charge is going to zero in a half a day or so, with out much use.
an icon is also appearing next to the charge percentage in the top right, and the icon is a circle around a lock
can anyone tell me what the problem is, and what the icon means?

The Icon meas your display orientation is locked to vertical so it wont change when you turn the phone sideways.
First thing you should check with the battery life is multitasking, which also happens to be where the orientation lock can be turned off. check out http://support.apple.com/kb/HT4211 and go from there

Iphone4s and iCloud/Apple Movie Trailers app stuck in loop using battery on wifi

This one is a long story and took me a day or so of looking around to figure out. I don't know if it causes all the battery drain issues, but it was at times causing some usage on my 4s.
Background:
I use my mac as an iTunes server - always running - so AppleTV can reach it etc via homesharing. I have a TimeCapsule too and a neat feature is wake on demand proxy where if the the mac is set for wake on demand and it is a sleep, the AppleTV will wake it via the proxy.   Works great. Even the iOS remote apps will wake it. Anything requesting a bonjour service that is active on that sleeping mac will wake it. All was good.
Then one day, I noticed it waking in the middle of the night - whenever the iPhone turned on with a notification. I thought that was weird. I quit the apps. hard reset, etc. Still occured. I could put the mac to sleep and just turn on my iPhone and it would wake. Note I have an iPad and it did not exhibit this behavior. I gave up for a few days. Mac would go back to sleep after 10 minutes so no big deal.
Side note I also have wifi sync OFF. I had it on for itunes syncing but noticed that iTunes maintained a constant connection to the phone even when not wired so you can drag and drop to the phone etc.    So to be sure that was not draining battery, it turned it back off. It also would wake on demand when it was enabled so I knew it wasn't that setting causing the issue.
Investigation:
I started with netstat and my airport logs. I found my mac address, ip address, and then found when I turned on the phone a connection established everytime to port 49166 on the phone.   It would create a connection everytime the phone turned on.
I used 'sudo lsof -i -P' to find the process opening the host port on the mac to that phone port. It was 'ubd'. Looking that up on google, I found it was the Ubiquity process.    I also found that it had a log in '~\Library\Logs\Ubiquity'. Looking at the log, I found the following occuring whenver I turned on my phone and usually very few minutes while the phone was on:
[ERROR]       99090c4718 [11/11/22 09:50:34.347] {D2650C3E} 264.connect-https://xxxxx-xxxxx-iPhone.local.:49166 parse_cert_challenge:608 signer 0: com.apple.idms.appleid.prd.4243556669426c674b3255694250464d4d41395633513d3d

I assumed those 401 errors were http errors. The logging would kick in whenver the phone was turned on.   I figured a loop like that must be using battery at least on wifi. I don't think it does this on 3g. I didn't know if this was related to the wake issue but it was the only clue.
I found a macworld article on problems with iCloud/Ubquity causing a hang. I didn't have a hang but I wondered if there was a file sync of some sort going on. I remembered reading somewhere that on OSX, documents for sync are kept in '~/Library/Mobile Documents'. So I looked there. I found one file called '43LU875E5~com~apple~movietrailer' and a hidden directory called '.ubd'. which has files with names and id's that matched some early parts of the log.
I was at a loss. Since it was a connection problem, I took Safari on OSX, turned on the phone, and connected to the https address in the log. Sure enough, I got messages from keychain to add roots and ccerts etc. Did this and eventually got an error returned. But it did connect which meant the phone was running a web server. Neat. And ubd wanted to connect to it and couldn't and was going to keep trying forever.
Since the only clue I had was the movies trailer data file, I went to my iCloud control panel and sure enough there is a movies trailer data file in iCloud (along with my ipad and iphone backups). So I tried to delete it . iCloud returned an error and could not delete. OSX console log showed an http 500 error.
So, I figure not much else to do, so I delete the app from my phone and my ipad. It even gives a nice warning when deleting that you have a file in iCloud that you may want to delete. Unfortunately, I still couldn't.
Final Testing
After deleting the app from the phone, I checked the ubiquity log. I could turn on and off the phone and it would no longer create the log entries, no netstat connection, no web server running anymore. I put the mac to sleep, and turned on the phone, It would not wake it up. Repeated test. Passed. Opened the Remote App and it woke up the Mac as expected. Everything was back to normal and I no longer had a looping connection between my Mac and my phone.   Note - this occured even when the trailers app was shutdown on the iphone. This appeared to be an iCloud sync issue.
Final Thoughts
- This did not occur with my iPad and it had the same app. I deleted it there to be safe.
- I have no clue how much battery this uses. I have pretty good life most of the time and my assumption is no matter what, it would help to turn this loop off. It was really the waking the mac all the time that had me bothered. I just stumbled on a bigger issue.
- I doubt the problem is occuring all the time. My ipad did not have the issue, only the iPhone. It was likely an anomoly that showed up and may or may not occur. I thought posting the experience and if anyone else is having similar problems this may help. I am not advocting that everyone remove the app. Just take a look around if you are using the app and are seeing issues.

Thank you!!! Thank you!!! Thank you!!! Thank you!!!
Hallelujah!!! Thanks for the correction (fat fingers, as you suspected).
Now to the good news. I started Safari, then pasted the URL in and pressed Enter. To my utter amazement the quicktime "Q" logo appeared briefly, then a "screen" box in the window and the movie itself began to load. After a short while it began to play, just like it should!
More good news. The exact same technique worked in Firefox as well!
Now the not-so-good news. When I enter the URL in Quicktime Player "Open URL", the player window opens showing the audio and video controls but no "viewing screen". I let it run for about 5 minutes and nothing ever appeared. I must qualify this by saying that right now my wireless connection is running very slow, so I will try QTP again when things are moving faster.
Believe it or not, this is the very first suggestion I tried that actually made a noticable difference. Of course, this is still a workaround (which I will gladly use). Hope there is a permanent resolution to this somewhere.
BTW, I plan on downloading and re-installing OS X 10.5.2 using the "Combo" package. My original install of both 10.5.1 and .2 were done via "Software Update" and this is the only other suggestion I've seen that might resolve my issue. My plan is to do the re-install only on the G5. If it corrects the problem there, I'll wait a week and then do the same with my MacBook.
In either case I will let you know the results in a follow-up post to this topic.

I have successfully run Apple Hardware Test and it returned the error code...
4SNS/1/40000001:VPOR
A Google search reveals that this is a sensor error. The "V" of VPOR indicates a voltage sensor and the "P" indicates the sensor is on the Power bus. However don't yet know what the "OR" refers to.
I have had a non operative optical disk drive for a year or more but the fault with the video only developed in the last week or two. Could the "O" in VPOR refer to the Optical drive?
By the way, I got the impression from the instructions on running the Apple Hardware Test that I had to use the internal dvd drive to run the APT program from the install disk. But this turned out to be not the case. Just put install disk ito an external drive plugged into the usb ports and use system preferences to set this drive as the start up disk.

cheers,

Most of the functionality and problems are in the drivers. The hardware tends to be discrete testable functions though these days there is a fair bit of functionality in the hardware. The hardware tends to be implementing better defined protocols where as the to and fro of the higher level protocols tend to be what varies from Access Point to Access Point. The 4965AGN is a fairly recent chip set and the drivers are far from smoothly running.
The problems can vary from AP to AP so may work at home but not at work etc. Some have reported here that the 4965AGN setup doesn't work with the Cisco 1200 Access Point and I have yet to be able to get it to work under Vista with the equipment at any New York Starbucks. T-mobile do use Cisco equipment but I don't know which models.
Anything you can do to simplify the situation helps. Maximum power. No security. Disable IPv6 on the connection etc. Just to give a rough idea of the kind of thing that might be wrong here are some of the things listed as known issues or fixed according to the readme of the driver (Originating from Intel) that was released for the 4965AGN on 4/11/08.
There are several authentication issues with EAP, PEAP and LEAP which will cause it not to authenticate. There are also Vista EAP issues and some things which may resolve with SP1 which was pushed out on update last week. So there are many comnbinations of situations which may not work and it is important to test with different access points. Authentication and security has more issues. Also at the higher speeds such as 54Mb some of the security mechanisms will not be able to keep up. AES is the only mechanism which Intel expects to work at 54Mb.
http://downloadmirror.intel.com/15806/ENG/relnotes.htm
There have also been past issues where the cards are silenced for twenty minutes after a failure to authenticate and in many cases the card will not be in a valid state after hibernation. It is noticable that when you phone T-mobile the first thing the tech has you do is completely shut the machine down - not hibernate - and begin afresh.
Once you have uninstalled and re-installed the drivers and connection manager a few times it is also possible to be having problems with junk left in the registry.
I don't recommend adding the 4965 drivers directly from the Intel site. I would wait for the one that has come through the Lenovo testing cycle.
In reality for those who don't want to make maintaining their laptop a serious hobby (Hopefully all of us - Far too much time is wasted on wireless) it is really a matter of rebooting your machine at a given access point. Trying your luck and then shutting it down and going somewhere else if it doesn't work. Use wires when you can. At home if your access point doesn't work check your configuratiions, temporarily remove all security, restore factory settings on the AP, reinstall from scratch and if it still doesn't work replace it with a different brand of Access Point.
Of course it is intended to just work and for 95+% of situations Wi-Fi does. The 4965AGN is newer so it has its fair share of early life issues to get resolved. Vista also still has issues. If the problem you are seeing is only when you are on batteries you are lucky and LANOgre's instructions may well solve it.

Why is my ipad still using battery power when switched off & locked away with no one using it?

Why is my IPad still discharging battery when switched off and locked away - with no one using it? Charged it to 100% on holiday and locked in safe. 2 days later it was at 76%!

How is it "switched off"? Are you pressing the button on the top so the screen goes black? If so, that isn't shut off, but put to sleep. I will still be doing things in the background and using battery power.
To shut it fully off, press and hold the button on top, you will get a notification on the screen that says "Slide to power off". Slide the button and it will turn completly off.
If this is how you switched it off, let us know and we will see what else we can figure out.

When not using battery often - good to let MagSafe always connected?

Hi all there – little question to have a longlife battery: on the Mac Book the battery is not used very often. Usually its on its place with MagSafe connected. Usually it doesn't have to load the battery (red) because it charges only after droping under 95% (I think its told in the manual).
So my question: is it good this way, that when using battery only 1-2 times per week, the capacity stays good. Or should I use it more often?
iMac G5 Mac OS X (10.4.8)

I agree - using the laptop plugged in all the time does nothing for retaining the battery life. My suggestion is to use the battery, even if your sitting here working. I do this on a regular basis - a bit ago, I let the system go on batt while I was working until I got the low battery warning, then plugged in and will let fully charge, then start the cycle over again.
Personally, I don't think that leaving it plugged in actually destroys battery life, BUT work with far too many people that just assume that because they don't use their battery (plugged in all the time), that their battery will fully function when they do attempt to use it. Keeping the charge/discharge cycle active as you use your system will keep the battery at it's best. All batteries have a finite life, usually great for about a year, after that they start to decline. At/about the 3 year mark, you can usually count on replacing them as battery life will have significantly degraded. This goes for batteries for just about everything using today's latest battery technologies (Lithium Ion, NiMH, etc).

Does nokia battery monitor 3.1 uses battery power ...

does it uses battery power if you put it in your home screen or it just observes how many power is left for your phone to last?

I dont think it consumes considerable amount of battery power.
It is somewhere, a little annoying to see when it shows for example, 14 hours remaining and all of a sudden after playing an hd game it shows 2 hours remaining! People think that it is because of battery monitor itself!
So no problem using it. It just observes how much battery is left and according to the usage and it calculates the time remaining.
It would be good if it show at what time the battery is going to last, that helps us to determine how we should use the phone to save the battery for the next busy day!

Macbook Pro random shut down whilst using battery

My Macbook Pro randomly shuts down whilst using battery power even though their is plenty of charge in the battery.
Any ideas??

does it do it when plugged in?
Also it sounds that there's a power failure and causing it to shutdown, I would get it serviced asap, the battery connector might be faulty.

I cannot use battery information when i upgrade kernel

Today I performed Pacman _Syu. I upgraded my arch linux kernel to 3.0.6-1.
I rebooted my arch system. After that, my arch system printed the error.
"Battery information not supported by your kernel!"
I try downgrading kernel to 3.0.4-2 and was able to use battery information again.
What is solution of not available latest kernel in my system?
My PC is ACER ASPIRE 1410.

The reason for the error message is probably the ONFIG_ACPI_PROCFS_POWER option, that was removed from the newest kernel. See FS#25845.
What application is giving you this error? Perhaps there is an update available for it?
Otherwise you could recompile the kernel yourself with the option set.

Can I use battery from my cellphone in zen micro?? does it f

I'm waiting for my zen micro, and i'm wondering that i can use battery from my cellphone becouse it has more capacity than original battery. Batteries from which phones fit in zen?(i'm from poland,sorry for mistakes if i've done any)

I've not heard of any specific cellphone battery, but I remember mention of a portable game system that had a similar battery (you have to pad with paper to get it to fit). I'm not sure you'll get any more runtime out of a cellphone battery though as I would imagine they all have similar energy density.
