Battery Remaining Indicator

The indicator doesn't seem to make sense. When it is fully charged, the Show > Time yields 0:10. With 40% remaining Show > Time yields 1:26. What am I missing? Thanks

It sounds like you need to re-calibrate your battery:

Battery percentage indicator does not show time remaining in ML as it used to show in Lion!

Hi everyone!
I upgraded to ML and have noticed that the battery percentage indicator does not show the time remaining (charge). you need to actually click on it to see how much time the battery is going to last. OS X Lion did not have this problem.
Is it just for me or is it a bug that Apple needs to fix?!?

IOS 4.2.1 iPhone 3G - battery drain / indicator problem

Since past few days this iPhone has started behaving strangely. Battery indicator will show as low (red bar) even when it's been on charge. Power off and on and it will show full but then over course of about 15 minutes the indicator will drop down to below 20% (get the 20% warning dialog) then it seems to settle at just below that mark. power off and on and remains indicating low battery.
Don't know how long it will last with that battery level as I am not the user of the phone.
Not yet done a full reset / restore, this will be the next thing to try.
Anyone know what might be causing this? Does it suggest that the battey is dying?

You might try calibrating the meter by draining the battery down until the phone shuts off, then recharging fully. It should calibrate after two cycles. When you plug the phone in it might take a few minutes for the phone to come back on.
Or, the battery could be getting weak or the charging circuit could be getting bad.

Battery remaining

HI,
I noticed some people are reporting the % battery remaining. When I look at usage all I have is in use time, and standby time. There is no indicator on how much battery remains. Is there some place else to check for this information, or does it require an app?

No, they are estimating from the bar indicator on the iPhone.

Battery life indicator?

Is there a more 'in depth' battery life indicator anywhere?
The battery icon top left isn't that accurate- i'd like to be able to see how much in terms of time i have left- is that do-able?
Can't find anything in settings...
Also- is there a 'home' shortcut for Safari do you know?

There are utilities for other phones that do this. Yes, it's useful.
Some are pretty simple: just look at the current average discharge rate and level, then figure out the remaining time. Pretty much like your car's computer telling you how many miles of gas are left at your current rate of consumption.
Pretty neat to watch the remaining time change as you turn on/off features.
One thing that surprises me is that no iPhone tech site has yet put a meter in line with the battery to find out once and for all how much power the different radios / features actually use. I've done calculations, but they're pretty rough. I mean, I've seen people claiming that WiFi uses more power than EDGE, and I don't believe it, unless they simply do more surfing because the WiFi is faster.

How reliable is the Battery Status Indicator?

I have had my MacBook Pro for a month now, and I don't know if I can trust my battery status indicator a the top of the MacOSX screen
It usually goes a lot shorter than the indicated percentage or the calculated battery life time.
I have another issue with this MBP.
Has anyone actually been able to use MBP for as close to 5 hours which is the battery life posted on the apple website?
I set my MBP to lowest backlight, no programs or widgets running, wireless and bluetooth off and kept it one for hours. The battery lasted a about 3hours and 49 minutes. Is there something wrong with this battery?

As you use your MBP on battery it collects information on your battery usage style and uses that to predict battery run times. based on that it's reasonable accurate providing you calibrate your battery ever 4-8 weeks or so. Also, the data it collects the more accurate it can predict your battery time.
Once you start using your MBP differently though the accuracy can vary but should still remain "reasonably" accurate.
I personally find the times reasonably accurate altough for the most part I run off the percentage rather than time.
Has anyone actually been able to use MBP for as close to 5 hours which is the battery life posted on the apple website?
No-one will ever get 5 hours. As you note from the specs it's "based on usage" or more to the point, it's non-usage. Those time are achieved by having it on my not being "used".
Average battery times should range from 2.5-4 hours depending on your actual usage.

MacBook Pro battery level indicator is stuck at 100%

Got this MacBook Pro in January of 2008. Great machine, replaced battery last spring and more recently had some sort of repair done when the screen would not activate. No problems otherwise. Now all of a sudden my battery level indicator is stuck at 100% regardless of actual battery charge level. The computer will allert me that it needs plugged in immediately or it will go to sleep, but it would be nice to have the indicator working again. Any ideas?
JG

If it's a pre-unibody MBP with a removable battery:
1) Shut the computer down
2) Disconnect the Magsafe AC adapter
3) Remove the battery
4) Hold the power button down for 5-6 seconds
5) Reinstall the battery.
6) Connect the Magsafe adapter to power and turn the computer back on.
This will reset the System Management Controller. One of the SMC's functions is reporting of the status and remaining charge of the battery.

Battery percentage indicator takes a little while to update when resuming from sleep - is this normal?

Hi folks,
I recently bought a new MacBook Pro with Retina (13") and have noticed a pecularity with the battery indicator that I'd appreciate an opinion on please.
I've charged my MBPr battery to full (100% on the menu bar and green light on the MagSafe connector). I disconnect the power and close the lid which puts that MacBook to sleep. After leaving it overnight, I open the lid and and the unlock screen shows the percentage battery having gone down by a couple of percent (which I take to be normal) - e.g. 98%. However, when I unlock and get back to the desktop, it's still showing as 100%. Clicking on the battery icon, it shows as calculating the amount of time left. After about a minute or so, it tells me how much estimated time I've got left, and the percentage indicator updates to give me the correct percentage. When using it normally, the percentage indicator drops on the desktop as I would expect it to.
Is this normal for it to give the correct percentage on the unlock screen, but then to give the original (pre-sleep) percentage when unlocked, until it has updated and worked out how much time it's got left on battery?
I've read elsewhere that many folks have been having issues with the battery indicator since Mavericks rolled out, and there are some resets that can be done by pressing various key combinations whilst powering on. I've had the MacBook only a few days, and haven't installed anything on it - it hasn't even been connected to the internet yet - so I assumed that it should be working correctly from the off - unless there's something buggy with Mavericks causing this?
I would normally shut down a computer overnight, but I like how the MBP instantly resumes when I open the lid. Am also wondering whether it'll take a few charge cycles before the battery reaches full capacity and is properly calibrated. The system report shows that it shipped to me having undergone only 3 charge cycles to date.
Any opinions would be much appreciated.
Cheers,
Gopha

After some more testing:
Disabling the battery percentage indicator and then re-enabling it causes the percentage value to update to the 'correct' value. Rebooting the MacBook also causes it to update to the correct value.
Seems like I'm not the only one with this particular issue: https://discussions.apple.com/message/24402123#24402123
https://discussions.apple.com/message/24406197#24406197
as a newbie to Macs and Mavericks, am I right in saying that there is currently an issue with Mavericks?
Thanks,

Battery Charging Indicator Light Is Out

I own a tangerine iBook, OS X 10.4 operating system.
For a year or so charging the battery while the power cord in has been a "fussy" project -- sometimes it wouldn't charge until I moved the "plug-in-to-the-computer" end of the cord out ever so slightly. I bought a new power cord, but that didn't change things.
I don't have internet at hom, so most days I take my laptop and power cord to the public library and use the library's WiFi to look for work. Yesterday I came home, plugged in the power cord, and no battery charging light. I "jiggled" the cord, got out the old power cord and tried that one, then I tried a different electrical outlet. No battery charging indicator light, and the battery is discharging while I use it with the power cord.
I'm assuming this is an electrical problem that I can't fix, but can anyone fix it? When the battery runs out, will the iBook keep running when plugged into an electircal outlet, or is the electricity not getting to where it need to be?
I've had problems with the battery not charging before, and once I was advised to reset something, but I've alway had the indicator light on, so now I don't know if power is getting to my computer.
I went to About This Computer, clicked on Power and saw this:
AC Charger Information:
AC Charger (Watts):    0
Connected:    No
Charging:    No
which looks like it doesn't think I'm connected to any power source.

Yes, if resetting the PMU doesn't work, it does sound like the DC-in board has failed.
It is not an easy repair (especially for someone who describes herself as "NonTech."

Battery Status Indicator (in menu bar) does not update

I've recently noticed that the battery status indicator in the menu bar gets "stuck," and won't update. I can force it to update by disabling and re-enabling it, or by changing the view style, but if I leave it alone, it won't change, even across sleep/wake cycles.
Any ideas?

Actually, the problem disappeared after a reboot. I reboot so infrequently, I didn't even consider that as a solution, but something else caused me to need to reboot, and after that, the indicator works fine.
Still no idea what caused it to get stuck in the first place, but for now, it's better.
Good luck!

What is causing flashing arrow next to battery status indicator?

I have a flashing white arrow next to the battery status indicator on my ipod touch that is causing music to be unplayable. Everything else appears to be ok. Arrow goes away when doing anything other than music. Any help would be appreciated.

Could be the Location Service icon . Go to SettingsPirvacy and either turn Location services on or off.
Next:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.

Excite Pro - Battery Status Indicator at 0%

Battery status indicator is stuck at 0% - battery holds charge ok just don't know what it is. I presume the battery stats file is corrupted - is the only way to fix it a factory reset?
Calibration either needs root - not possible or 60% charge - won't work as says 0%!!!!

I think you should set it to factory settings.
Press and hold power button and volume up button. Then in the menu choose factory reset.
If this will not work, then the issue must be related to hardware failure

Nokia E75 Battery Status Indicator?

Hello, well i have a problem. on most phones, if you go in the settings, there will be a section where it says all of the phone status. and i find this really useful when it comes to the battery. But on the Nokia E75 i cant seem to find the battery status indicator. Does anyone know where it is?
***Battery Status Indicator is where is says how much percent of the battery is left.

Faulty battery maybe. The battery has circuitry that reports its charge level and it sounds like that isn't working. You should have it replaced under warranty if possible!
