Battery leaking/bad battery meter?

So, earlier today my battery was showing at least half of the battery being left. I was in class listening to music when suddenly the phone just turned off.
I figured it crashed and all, but when i tried to turn it back on it said my battery was empty (?????) I am not sure if the battery meter is bad, or my battery is broken, I just know that the phone was showing enough battery to last me all day, and then it suddenly turned off. Anyone else have this problem?

I am a new owner of an iPhone 3G ( < 2 months). I've come to live with the shorter battery life than I'm used to in previous non-PDA phones. Until yesterday, I've been very happy with the phone. But yesterday I went almost the entire day without charging the phone and ran the battery down to less than 20% (according to my battery meter and guessing based on an eye ball guessimation). So I plugged it in to charged it and it was almost full (not quite but probably 90%). I unplugged it and took it with me for about 2 hours. During that time I did not used it once. I got back home and took it out of my pocket and unlocked it. Now the batter meter showed less than 50% battery life (FYI - Bluetooth was off the entire time). Did I kill my battery by running it down that far (if this is the case than that is ridiculous) or is there a bug with the batter meter (similar to the bug with the signal strength meter that 2.1 fixed)?

Battery meter haywire

Today, I was using my iPhone 3GS (3.1.2) regularly and I eventually found myself down to 11% by mid-afternoon (under this exact same usage per day, I am often around 60%).
I shut off my iPhone, and turned it back on, thinking this would solve the problem but it did not. Next, I plugged it into my charger and watched it charge rapidly to 19% within 2 minutes. Then, I disconnected it and played some music and it stayed at 19% even after five minutes of music playing (which is a good sign since a full charge should net 30 hours of audio playback).
I plugged it back into my charger and right in front of my eyes, I saw the battery meter jump from 19% to 55%. Instantaneously.
Is there a physical component of the battery meter gauge that could have gone bad? Is my battery going bad, after only a few months of use?

I'm not going to discount the "you have a bad battery" or "You have push applications draining the battery" theories. However, if the iPhone is not getting physically warm to the touch, then I'd discount the high-drain theories.
I've had battery gauge wierdness myself, with the % available plummeting very rapidly down to single digits, then *staying there* for hours.
In my case, this happened not long after I'd completely discharged the phone, then had a failure to re-start during the mandatory 10-min waiting with low battery sign as it was plugged in. I got a white-screen boot, which a hard reset (hold power and home button) fixed. But after that, battery gauge wierdness...
In my case, I did a restore-from-backup as a new phone with firmware reload, and then did a couple of complete charge-discharge cycles, and now the gauge is behaving relatively sanely.
I hypothesise that something in the firmware "learns" the battery charge characteristics and uses that to display percentage remaining, and that whatever code / data is associated with this is vulnerable to "mis-learning" or corruption.
In short: I don't think the battery gauge is always correct, but I don't think that this actually affects the battery life you get out of the phone too much.

Battery Meter Inconsistant

Ok, I have reset, restored and updated my ipod, and re-uploaded itunes on my computer... and my ipod mini (2nd gen) STILL has a wierd battery meter.
After, for the second time since I have gotten it in December it actually said "Charged", I played it for 2 hours, turned it off when it had barely dented the meter. Turn it on 2 days later, and the apple icon comes on, and then the meter says it's empty. About 5 minutes later, it says it is full again!
Is the battery bad? Should I send it in?
I have tried to fully charge it several other times, and up to 18 hours later it is still charging. Yet this time, I charged it for 3 hours and it went to fully charged.. I am confused.

Battery Meter/Shutdown despite charged-- no previous answers

I've searched the fora for an answer to this problem, which strikes me as quite bizarre, but I can't find any answers.
I have a 2nd generation iPod mini purchased direct from Apple in August 2005, so it is within warranty.
This issue has happened countless times during playback and once directly upon disconnecting from my computer (fully charged). Despite being even fully charged, I will get a dead battery notification and the iPod will shut off. *However,* if I consistently restart the iPod, it may play again for hours with no further disturbance. Even stranger, the battery meter itself will read that the battery is nowhere near run out, yet the iPod will still shut off and require restarting.
I've restarted my iPod countless times, have tried to recalibrate the meter, and recently did a Restore, but the problem hasn't changed. I know the battery itself isn't dead, but I'd thought it was a software problem. Does anyone know what to do?

You may have a battery problem (hardware). See this article on battery charge problems, and, since it sounds like it is the battery itself, you probably want to read this battery service FAQ. Lastly, you may want to read this article on determining your battery's life to see if it is bad.

Frozen battery-meter and clock

Every now and then (quite often, actually) - the menu-bar at the top of my screen freezes - making the clock stop and the battery-meter freeze. This means from time to time I have no idea that my battery is running out of power, and the macbook suddenly shuts down! The last time this happened it went on for about 3 hours without being able to update the battery-meter or clock!
What can I do?

I was able to figure out the cause and solve this issue on my end.
I opened Activity Monitor and saw "SystemUIServer (Not Responding)", so I looked up process:
http://guides.macrumors.com/SystemUIServer
Apparently, SystemUIServer manages the 'menu extras' on the upper right-hand side of the menu bar. There was also this other useful tidbit of information:
"A bad hardware state may cause the SystemUIServer to hang. Often, unplugging the external device will unhang the SystemUIServer"
"The SystemUIServer is owned by the logged in user (as opposed to root) and automatically restarts if it crashes or is force quit."
I had recently started using on of my older iPods again, so I guessed that maybe it was the device in a "bad hardware state", so I unplugged iPod (super old 3rd gen 15 gig...formatted originally on Windows...back when I was a PC)
Right away the SystemUIServer process unfroze in Activity Monitor and the upper right hand menue items are no longer hanging.
So my advice to others with this problem is to unplug devices from USB (iPod, etc...) and see if it eventually unfreezes.
I've seen iPods hang Mac OS during bootup as well, but this is a new one for me.

How can I recalibrate or reconfigure my Treo Pro's battery meter ?

Hello ! I've got a problem with my Treo Pro and I'd like to get more information about the solution.
I've bought a new extended battery (2400mAh). It works very well, but my phone's battery meter doesn't give me correct datas about charging level of the extended battery. I've heard about the same problem on other forums from other people who use extended batteries. Independent on the manufacturers, they have the same problem with their Treo Pros. Please, help me. We have to use extended batteries, because the Palm's original battery (I think it is a 1500mAh) isn't fit to anything (my 1 month old phone works with its original new battery for a 3 days). My phone works very well with the extended battery for about 6 days. During this period in the first 3 days the battery meter runs from 100% to 0%, remain on 0% in the next 3-4 days until it depleptes and it annoy me with its messages (please charge the battery avoid losing datas and so on).
So I'm searching for any registry hack, recalibrate phisical methods, idea or any other way to reconfigure the battery bar. Please, help me or give me more information about the developer's e-mail or developer's forum.I'd like to solve this problem.
Thank you for your help.

Why is the battery meter so annoyin?

Ok heres the thin, i got my 5g black 30gig ipod two weeks ago...everythin was fine, until after the first full charge i noticed after about an hour of music the battery meter was down to 3/4 of a charge and kept goin down dramatically, after reading some of the disscussions i did the update and charged it untill it said full, so then after about 4 1/2 hours its in the red, so obviously it still goes down quite fast, to calibrate it at the moment by runnin it till dead, so has anybody else had this problem, and what happened to you....another thing what is the best way to charge it...through an ac adapter or computer.

ok...using my ipod normally (between .5 and 1 hour a day right now) the battery lasted about 8 hours....so it ran for 3.5 hours in the red...this is really dissapointing although it says that it will run 8-12 hours, but also realizing that was the first time doin a charge discharge cycle to try and calibrate it but after charging it the meter is doin the exact same thing...after fully chargin it, the second i start playin music the meter goes down...now the backlight timer is 2 seconds, the eq is off, and the library is on shuffle...and i only change songs once in a while...so why am i only gettin 8 hours?

Battery meter reads only 0-1%, or 99%.

OK, well this a little hard to explain but I'll try my best:
Basically, one day a couple weeks ago I took my PowerBook to school and had it in class and basically drained the battery completely to 0%, managing to still continue working about 30-35 minutes after reading 0%. OK, so it powers itself off and goes to sleep. Understandable. I put it away and charged it back up at home later that night.
The problem now is that the battery meter up at top no longer gives me accurate readings on the battery. When the battery has been charging for about as long as it usually would take for it to say 100%, it stays at like 2%. Sometimes, it'll just jump right from 1 all the way to 99%. Ok, like right now it said 2% but now went to 1% even though the AC adapter is still connected and the light has remained on. I have not seen the percentage say anything between 3 and 98% ever since the day I used it in class. It will go from 0-2%, then occasionally to 99% and back to 2, 1, 0. To make this problem seem even a little more strange, before this problem started showing, the computer would rarely start itself up again in the morning without being plugged into the wall first. Essentially, it would become "cold" overnight, and I'd have to plug it in first to the wall to start up. NOW, this thing always wakes up from sleep in the morning or basically whenever no matter how little battery life I think it has.
I got my computer in Jan/2004 and it still has the original battery. Needless to say, I was already getting some pretty short battery life. I'm not sure what the proper procedure on batteries in these things are, if I should have replaced it by now with a new one?
HELP!

(FYI, the meter has now been stuck back at 2% for about the last 10 minutes.)

2.1 firmware update displays incorrect battery meter

After installing firmware 2.1 on my iphone I started noticing my battery meter displaying the incorrect charge level. I charged it in full yesterday, and this morning I still had more than half the battery meter. I checked 10 minutes later and the meter was now showing 10% left with the red battery meter.
I went ahead and charged it again , used it for a while and now noticed that the battery meter is not only showing the incorrect amount left (still) but shows a different battery status on different menu screens. Shows battery meter to be full in the home screen and half the meter on an app, email ,etc.
Firmware 2.1 has definitely messed up the meter!
inaccurate reading on the battery meter , someone else has to be experiencing this same problem.
let me know if someone else has this same problem !

try draining out the battery first and then recharge it, see if that shows an accurate. I had that happen to me on the 2.02 update. The battery meter was inaccurate. Like when i reached 20% it was actually at 50% when i plug it in to charge. So i did sent them a feedback about it. So I'm hoping that the 2.1 fixes this issue. So far my battery is showing at 100%.
Usually for me at the end of the day after a full charge in the morning, the battery meter would go down 1 bar. So i'll have to wait and see.

IOS 4.1 on 3G - Battery Meter Wrong

Has anyone had problems with the battery meter after updating to 4.1? The meter is correct while discharging, but not while charging. To get an accurate reading after a charge, the only solution I've found is rebooting the phone. I've tried several times with the same result. Also, I've tried draining to see if recalibration was needed or something. Any help would be appreciated.

Greetings,
There is likely no issue with your phone/software, other than you may need to calibrate the meter. That old phone can have a meter go out of calibration with the installation of iOS 4.1, especially if you are going straight from 3.13.
All you have to do is to charge it up overnight, then run it down all the way until it shuts itself all the way off, not just go to sleep. After that let it rest a half hour or so, and fully charge it, without using it. It's best to plug it in, and then do a full shut down, and let it charge fully. The meter should be in calibration, after that.
I've seen some folks have to do this a couple of times, if they continually short charge it, but once is usually enough.
I wouldn't pay too much attention to what the meter says while it's charging, as other things are going on that will make the meter fluctuate a bit, since it's on.
Cheers,
M.

Does anyone know the name of the app to change my battery meter etc.

I cannot remember what it was called but someone told me that i could personalize my battery meter his was a pitbull that changed colors . can anyone help pls ?

i think it is a hack app. or something like that .

Time, airport, battery meter will not display.

Hey I have an ibook g4 that does not want to display the battery meter, sound volume, time & day. for some reason. I have looked all over system prefs and got nowhere fast. If someone can let me know whats up...please do. I have tried to right click over it and everything. thanks.

I'm not interested in ascribing blame either but waiting for Apple to fix something that isn't broken will only divert attention from seeking the problem's underlying cause. Assuming the AirPort Utility app on your Mac remains unaltered, it's exactly the same one everyone else is using. Should there be any doubt about that, reinstalling OS X will obviate any concern.
I suggest the following for you to consider as you deem appropriate.
Apple's Wireless Diagnostics may supply some additional helpful information.
To use it, hold an option key while you click your Mac's Wi-Fi icon, and choose Open Wireless Diagnostics...
The following authentication dialog will appear:
Authenticate with your Admin password, then click the Continue button in the following:
The network analysis and diagnostic tests will take several minutes to complete:
When it completes, if your wireless network is functioning properly the following will result:
If something is amiss, supposedly the results will be different and you will be presented with helpful information.
Assuming your connection is "working as expected" select Continue to summary and click Continue:
Ignore the pre-populated text field, which is provided as a place for you to type in additional information should Apple ask for it in the course of obtaining technical assistance from them. Apple has no way of knowing where your router is located in your home, and certainly doesn't know if you even have an upstairs bedroom closet.
Click Continue.
The next step will also take a few minutes:
When it finishes, you will be presented with a summary that may or may not be useful to you. Let me know if it is.
The WirelessDiagnostics-xxx.tar.gz file deposited on your Desktop can be dragged to the Trash, or you may wish expand it and examine its contents. It's up to you.

Clamshell - battery meter problem?

Somebody has to be able to explain this one to me...
I bought a used graphite 466 to hold me over until I can save up for a brand new laptop. It was running like a dream, at least until...
I turned it on one morning, as I usually do... and the battery meter was acting really weird... I still got my 4 hours of use out of it, but the meter very slowly ticked down to about 95%, then took a huge nosedive down to just 5% in an instant... I was forced to run off the adapter until my class was finished, and I brought it home...
I was at home, adapter hooked up so I could recharge it while I continued using it. The charge slowly crept up to maybe 9 or 10%, then jumped straight to fully charged. That was the point where I realized something was very wrong... so I scoured the support pages, and the discussions, to try to find something that matched what was happening with mine.
I did the PMU button, reset the NVRAM through open firmware... I even let the battery run down fully and took it out of the laptop for the night...but there was no change...
Next, I decided to download one of those programs to check the battery... and either I'm very confused, or the numbers just dont add up.
According to XBattery, my battery stats right now (fully charged and running off the adapter) are:
installed: yes
charging: no
charger: yes
battery %: 100
(so far, all makes sense... what a fully charged battery should say, I would think... but then it gets weird)
Max. cap: 3.600Ah
Curr. cap: 64.860Ah
Charge: 64.860Ah
(this part makes me think maybe the labels for these numbers are mixed up somehow... how could my current capacity be that far above the max?)
voltage: 16.858v (the adapter itself says it should be 18v, but this is close enough)
amperage: 0 (it's not currently drawing any power from the battery... i guess?)
cycles: 80 (charge cycles, I guess...sounds way too low for it to be a battery problem... )
Flags: 2d000005 (no clue... I'm sure they mean something, but I don't know what...)
Now, I'm no expert as to what all those numbers really mean, but my impression is that it's not a battery problem per se....
Anybody have any idea what's wrong with my machine? Is there something simple that I'm missing here?

I ran a terminal command to show my battery information:
"IOBatteryInfo" = ({"Capacity"=64860,"Amperage"=0,"Cycle Count"=90,"Current"=3363,"Voltage"=16415,"Flags"=754974725,"AbsoluteMaxCapacity "=3600})
While I'm no expert, I think I have at least some grasp of what it's saying...
Capacity is 64860mAh, which XBattery lists as 64.860Ah... different units, same thing...
Cycle Count is now up to 90... that's fine... I've charged and discharged a few times since last time I checked the count...
Amperage is at 0, even though the menu says it's charging... not sure how that is true...
Voltage is 16.415... not too far off from the 18v listed on the outside of the power adapter... that's acceptable...
For the flags, 754974725 in decimal is the same as 2d000005 in hex, which matches XBattery...
The part I don't get is... if I'm showing a charge of 3363 out of a max of 3600, why is it only at 5%? The only way it could be was if it was comparing the charge to the current capacity... 3363/64860, which is about 5.2%...
For some reason, the computer is not giving it more power, because it's so close to that 'assumed' capacity... 3600 space left on a 64860 battery, which would be around 95% charged... and that's before counting the 3363 I 'persuaded' the battery to accept... But when it checks capacity after I unplug the adapter, it is nowhere close to what the machine was 'assuming' while the adapter was connected...
I would think my computer (or any computer for that matter) would be smart enough to at least pose the question as to why the 'max capacity' is so far below the 'current capacity'... It's like saying 'This basket holds 36 apples maximum, but currently, it's holding 640+ apples... it doesn't really make much sense... There is no situation in which both statements could EVER be true for that one single basket, or my battery in this case...
You'd think an error screen would pop up or something: "The battery is currently sending unreliable and conflicting capacity data, so therefore, time and charge percentage are unable to be calculated in any reliable fashion..." Then it should instruct me on what to do to correct it... Or, at the very least, suggest that I call for assistance... right?
This issue has evolved from weird to downright annoying... I just wish I knew what the real problem was so I could fix it already!
