10.5.2 caused battery meter problem

before 10.5.2, the battery meter is working fine. After 10.5.2, when the battery meters shows 20 min left, it suddenly changes to about 1 hour. then 20 min later the macbook will suddenly shut down without any warning. This has happened twice since yesterday.

Maybe try "resetting" the battery by letting it run ALL THE WAY DOWN until the system goes to sleep, and then plugging it in and letting it charge fully.
This is good battery practice for all Macs of all OS versions, to do once a month or so.

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!

Is the latest version of ipod software causing battery charging problems?

I have access to three different G3 ipods. All of them charged fine (either on AC wall charge or through firewire through the Mac. Now all three have the same charging problem after update to the latest Ipod software. All seem to recharge for only an hour or so then stop charging and show the large full battery icon but when disconnected show less than a full charge on the small meter. If you plug it back into the charger or firewire it will again begin to charge as shown through the large icon. Unpluging and replugging will eventually get to full charge on the small icon it takes at least three times to get it there. It's really annoying and based on the sheer number of posts about this problem,one must suspect that the battery management software must have changed. Has anyone noticed the same coincidence?

Is this problem related ot the 5G ipod?

Is iCloud causing battery draining problems?

I have been using my iPhone4 and my iPad2 flawlessly with my mobileme account for as long as it came out. The other day when I upgraded to Lion and started using iCloud, my batteries on all my devices including my MacbookPro have been draining RAPIDLY. I changed a bunch of settings on both the iPhone4 and iPad2, but nothing seems to be working. Even the battery on my Macbook is showing 96% and I haven't unplugged it in DAYS! It seems as though something is draining the battery life in all of my devices and the only thing I think it can be is the iCloud. I have been reading a bunch of topics on this and many people seem to be having the same problem. OH HOW I WISH I COULD GO BACK TO mobileMe!!!!! Why did I ever upgrade? Anyone know when apple will be coming out with a fix for this?

Is this problem related ot the 5G ipod?

Recent update from ios 7 to ios 7.1 has caused my wifi button to grey out on my i phone 4s, and caused battery usage problems on my i phone 5s

Can anyone solve this problem, I have been told just to wait
for the next update which will fix it.

If your phone is in recovery mode, all data on it are gone. Certainly before performing a software update, you backed up your data and imported your important photos onto your computer, right?

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:

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.

Does 4.2 fix 4.1s battery drain problem?

or make it worse?

Neither. 4.1 does not have a battery drain problem, your iPhone has a battery drain problem. You need to fix the problem at its root. Every version has caused problems for some people, and it isn't a problem in the release, it is a problem with something getting corrupted during the update process. Here's the evidence:

Battery Meter Red, Not Charging when plugged

Last night i was using my phone to browse and surf the net. the battery was running out finally it gave me a graphic that i need to plug it in. The graphic was a plug + the electricity symbol. So i plugged it in and the plug and the electricity turned into just the electricity symbol. so i went to bed and when i woke this morning, the phone was on the same screen. It had the battery meter in red, the electricity symbol on the but no charge. So i checked the plug on the wall, and it works. So i decided to plug it in to the computer and still the same. No charge going through.....
I restarted it while still plugged and nothing.
so finally i restarted it, unplugged the cord....then replugged it and it finally started getting charge...
Has this happened to anyone? Or is there some kind of safe gaurd that i dont know about and just making a full of myself on here?

Ok I think I have an answer. This happened to me twice and both times, it resolved the same way.
CAUSE: Both times, this happened when I let the battery run down too much. I was playing a game or listening to music and ignored the low battery warnings thinking I could push it and eventually the iphone shut down. No problem, I thought. I can just plug it in and keep on going. But when I plug it in, the iphone won't charge ... like it normally does. I get the red battery meter and the plug and lightning symbol as previously described. The phone won't turn on. I tried resetting it several time - hard resets as well - with no response. Always to the screen with the red battery.
SOLUTION: What i did both time was to keep the phone plugged in for at least 4 hours and maybe even more. I noticed that the red battery symbol flashes when it is not plugged in but when it is plugged in - the red battery symbol does not flash. Even though the phone is non-responsive in every other way, it seems to recognize if it is plugged into a power source or not. So I kept it plugged in for several hours. By the way, the phone is totally unusable during this time.
After that time period - I did a hard reset and the phone booted up with the white apple symbol and I started recharging again - this time it took.
I did this TWICE so I think it will work in the future.
THEORY: I am not a computer person (I'm a gynecologist in real life) but I will try to explain this behavior as best as possible. I think when the battery runs down too low it shuts down. But it shuts down EVERYTHING! Even the software that charges up the battery - which is a bug that Apple needs to fix - but everything shuts down. So this may sound stupid but it seems that when it is shut down to this degree the phone does not know how to charge itself. That is why nothing works. The phone remains shut down. It does not reboot. It does not charge up. However, as noted above, the phone does seem to recognize when it is plugged in to a power source or not as indicated by the flashes on the red battery symbol. It flashes if it is not plugged in and it stops flashing when it is plugged.
Anyways, even though the phone does not know how to charge up, it is charging anyways - but only by a trickle. A microscopic trickle. And it takes a couple of hours via this trickle to charge up the phone to a certain level to be able to reboot. After the reboot - you have to charge up the battery again - but since the phone is now working, it knows how to charge itself up normally.
Again, this is an amateur theory but I can't explain this behavior any other way.

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.

Ipod touch 5g battery life problem?

Hi everyone, i just got thenew ipod touch 5g 32gb blue about 3 weeks ago and it runs ios 7.0.4. Now i have been thinking that i might have a bad battery because when i play games the battery runs out in labout 2 hours. i play games like wipeout and clash of clans. Also the ipod touch charges in about 45 mins from about 20 percent to 100 percent. On the apple website it said that it should take 4 hours. I use toua abelkins wall charger. Plz help me because i do not want to retuurn this ipod touch and there is no apple store near where i live. P.S. I have already tried restoring it but to no use. Also i would to know why the battery indicator goes up a lttle when i lock my ipod. Is this a ios 7 issue? I have also tried calibrating the ipod touch by letting the batery fully drain and then charging it up to 100 percent but to no avail. My freinds said that you have to completely drain your battery til auto shutdown when you first get it out of the box but i did not do that so could that bethe problem? And when the ipod auto shuts itself down the i plug in the chargers and it boots up right away, i thoutgh it was supposed to take 10 mins??? Plz help me because i love my ipod very much???!!!

Battery life on the iPod 5 running IOS 7 is well ... poor for gaming. To fully charge it takes around 4 hours +/-. The battery meter jumping around is normal, the metering system on this iPod is at best an estimate and will vary up and down depending on how hard your working your iPod. Run games or anything with high res. video the meter jumps down, listen to music from you library or put it to sleep and the meter will go up-- And will drive you "NUTS" if you spend to much time watching it. Your game time seems a bit short, but the more stuff going on, higher graphics, using Wi-Fi etc. will drain your iPod in short order. Most seem to get about 3 - 4 hours of gaming, 4 - 6 hours of video, more if watched on lower resolution. 6 - 9 surfing the web, something around 18 - 20 hours listening to your library with the screen mostly off and about 36 - 40 hours on standby from a fully charged battery. Don't bother with getting the meter replaced with %. It will not work any better, just make you nuts. As for the theory of drain the battery then fully charge it, Bogus! These things use Li-ion batteries, they don't have memory issues like Ni-CAD batteries. Just watch your 20% warning with the battery, thing of it as a low fuel light on your car, when it comes up charge your iPod. You never want to completely drain a Li-ion battery if you ever do it will never charge again, but they have charge protections to prevent you from doing that. Long story short; If your getting something around the use times listed above, it's normal. Goggle C-net about extending battery life many good things to try. Hope this helps, Good luck.

My iPhone is split from front panel on top, and back cover of my is swollen too. I am not able to use my phone and I cannot access my data in the phone. Please suggest what could be the cause of this problem?

It sounds like the battery might have gone bad, and is swelling and causing the symptoms you describe. Do not attempt to use the phone, but take it to Apple for evaluation.

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.
