Why not an External Battery Level Indicator?

One of the features I really like on my MacBook Pro (and all previous Apple laptops I owned) is the small little button in the bottom of the computer (in the battery) that allow us to see the battery charge status without having to turn on the computer (Press the button next to the lights and the lights will glow briefly to show how much charge is left in the battery.). I found it really useful and allows me not to charge a battery that is already charged.
Anyways, as far as I can tell, the MacBook Air lacks this feature. Can anyone confirm this for me?
I don't think it would be very difficult for Apple to incorporate this in the bottom of the laptop.
Cheers

You are right, it's not on the MBA.
I do miss it too.... more than the DVD, Firewire or Ethernet jack everyone else complaints about...

  • Battery Status Level In Desktop Manager Does Not Agree With Battery Level Indicated On My Curve 8330

    I just got a new Curve 8330 from Verizon.  It came with a Desktop Manager 4.3 disc.  I installed it, but then learned that version 4.7 was available.  I uninstalled 4.3 and downloaded and installed 4.7 from RIM.  When I started to charge my Curve via USB cable to my PC, the Desktop Manager showed a battery charge of 37%.  My Curve was 100% charged later in the day, but the Desktop Manager still indicated it was only 37% charged.  I uninstalled 4.7 and reinstalled it, per advice of Verizon.  Then the Desktop Manager correctly showed a battery charge of 100%.  But as I used my Curve and used up battery to a 50% level (as indicated on the Curve), the Desktop Manager still showed a 100% charge.  A minor glitch with the Desktop Manager software?  Any solutions?  Thanks.

    it's a glitch. The(false) value can be updated by going into the Help menu if I recall correctly.

  • 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.

  • Labview FPGA: Why not have local variable without indicator?

    In Labview FPGA, to transfer data among parallel loops, there are three ways or maybe more, local variable, global variable and block memory. The problem with local variable is that it needs an indicator along with, not like global variable. I was thinking why Labview doesn't make a kind of local variable not need indicator? I guess local variable itself doesn't cost resource much compared to global variable, however when it comes into indicator, it will cost more. Just an idea, though. I guess there is a reason NI doesn't do that. 

    As in Labview document, global variable can be used for transfer data among VIs, which local variable isn't capable of. 
    Global variable is not always a better solution. From my experience, it is still unclear among different compilations using local vs global in terms of resources. A thread here http://forums.ni.com/t5/LabVIEW/FPGA-global-variables-vs-front-panel-items/td-p/1407282 talks about that too.
    Stephen, is there any documents say that global makes timing worse? I didn't see this noticeable.

  • Why would cause my battery Level to read incorrectly?

    My level shows 90% and above all day. I switched to time instead of percentage and it says 2:26, now the percentage says 87%.
    Any ideas? The macwas made in 2008, Alum/MacBook 13".

    Welcome to Apple Support Communities.
    You likely need to calibrate the battery. It would not hurt to reset the SMC and also the PRAM.

  • Battery Level indicator is eratic

    This weekend my MBP battery indicator has been acting very eratic. I put the machine on charge. Take off the power cord and it shows 100% charge, but says i only have 1hr 5 mins of usage. Yet as recently as yesterday that would show 3 hours plus. As im typing this post the indicator has risen back from 42 mins remaining to show 50 mins. (oh scrap that it suddenly dropped to 46mins again) I have 69% of the charge remaining. The indicator on my battery is showing 3 1/2 lights.
    Do i need a new battery? Is it normal for a battery to go from full performance to this without any period of decline?
    Any help appreciated.

    You might try resetting the SMC and calibrating your battery:
    http://support.apple.com/kb/HT1411?viewlocale=en_US
    http://support.apple.com/kb/HT1490
    Your battery should have up to 80% of its capacity at 300 cycles. How old is the battery? They do decline with age as well as with cycles.
    Also, check the battery carefully for any distortion, bulging, or leaks. Here is another battery article that might apply if you feel your battery has a problem. It will describe the characteristics of a faulty battery:

  • Low battery level indicated on BT Keyboard

    I went several months on the included alkaline batteries that were included on the included Apple BT Keyboard. After that I switched to Energizer Rechargeable (2500 mAh), and since then performance has been very poor. I can put in a fresh pair and I'm lucky if it shows 50% battery life. Constant disconnects, as well as the range of the device seems less. Is the keyboard a demanding device, are these batteries underpowered? I've had no issues with these batteries in other devices, including the magic mouse.

    Rechargeable batteries are only 1.2 volts as opposed to the alkaline batteries which are 1.5 volts. It will not show 100%. I just put rechargeable batteries in my mouse. It showed 75% at first. Quickly went to 50% from there, but, they are holding up well since. I plan to use the alkaline in the keyboard since they last a long time as oppose to the mouse.
    Try putting alkaline back in the keyboard and see if you get 100% reading. I don't think the keyboard is more demanding, but since it uses less battery than the mouse, I would just leave use the alkaline if you have no problems with them.

  • Battery Level Indicator with Logitech V270

    I have the Logitech V270 Bluetooh mouse with my 15" G4 Powerbook. The mouse works great, but in the system preferences under Keyboard & Mice in the Bluetooth section, the battery indicator is greyed out and there is no mouse listed. Is this only for the Apple Bluetooth mouse? Thought it would be nice to see my batteries life in my Logitech.
    Thanks!

    I am using a Logitech V270 with a Mac Mini with built-in Bluetooth.
    I have the same issue in the Keyboard & Mouse / Bluetooth preferences; the mouse name and battery indicator are grayed out.
    I think the Logitech mouse is only minimally compatible with Mac OS X and its implementation of Bluetooth.
    Furthermore, Logitech doesn't have any Mac OS-compatible software to enable button re-assignment on the mouse.

  • Why doesn't my battery charging indicator shown during charging?

    Hoping somebody can help. Ever since the install of IOS 6 when I plug in my iPad I hear the sound the when the attempt to charge is recognized. It the indicator no longer shows on the screen.
    Thx

    The charging indicator shows on my iPad running iOS 6.
    Have you tried restarting or resetting your iPad?
    Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPad shuts down, then press the On/Off button until the Apple logo appears.
    Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off".

  • Wireless Keyboard Battery Level Not Changing?

    Hi,
    I have got a new iMAC machine 21.5" , almost 6 weeks since. I am a regular user. The machine has Mountain Lion OS 10.8.2.
    In System Preferences, I can see the Battery level for Blue tooth mouse dropping to 57%, but the keyboard has been showing 100% all the time.
    Looks like this is a bug. How do i check the Keyboard Batter Level.
    Regards,
    Vinay

    I bought an 21.5" iMac eight months ago and I did note that the battery level wasn't changing for my Wireless Keyboard as my Magic Trackpad slowly used its batteries up. That being said I changed the batteries in the Keyboard when the Magic Trackpad died assuming the Keyboard was soon to follow and now the battery level is reported accurately. In conclusion I believe that the Energizer Advance batteries that are shipped with the Wireless Keyboard, Magic Mouse and Magic Trackpad had a lot more to do with the problem then the OS. I don't know why only the Keyboard was affected but I do know that now I am using regular Energizer batteries and all is normal as far as usage levels. Hope that helps.

  • Inaccurate battery level

    Here and in other places, I have seen several complaints about lack of a correct battery level indicator. This seems to be the case with more than one phone model. Considering short battery life, it is a real problem that battery level cannot be checked with any accuracy. I sometimes have 7 bars when I turn off my 6220 classic, and 4 when I turn it on again after a short while. This shows that the firmware checks battery level very seldom or that the procedure has very little precision. Checking with PhoNetInfo or NSysInfo gives the same result. They seem to reflect the firmware's reading.
    It cannot be so difficult to make the firmware check more often. Why has this not been done?
    Is there no software that is capable of doing its own direct check?

    it's not difficult to have the software or firmware that check batt level more... pool more but:
    - The more you do, the more batt it's used... therefore shorten your batt life again.
    - The batt has IC chip built in, and the batt after you use a while capacity is less and less and your chip may malfunction, which may give you incorrect value and batt life shorts.
    Even if you turn off your phone it still used the battery as if you set alarm and turn off, it will turn on and sounds.
    This is a feature too that ppl want...
    Hope this helps

  • 10.5.8 won't show UPS battery level

    I just installed an APC Smart UPS 1000 VA UPS to my Mac Pro server.  The USB cable is plugged in and the UPS battery is fully charged according to the display on the UPS itself.  The Energy Saver control panel is the APC preferred control method (they do not supply software for MAC OS X after 10.4) and all the controls appear as expected with the exception that the Battery Level indicator at the top of the Prefs panel shows 0% full.
    I've unplugged and plugged it back in to no effect.  I restarted the server.  I turned off the power at the wall switch and the UPS ran the server with no dramas for about 10 minutes.  Nothing I tried had any effect.
    There is nothing in the APC support site other than instructions for using Energy Saver panel.
    Our power here has been pretty flaky this year and I want the server to gracefully shut down after about 10 minutes of an outage.  It won't work if the UPS won't talk to the copmputer.
    Steve

    Have you checked to see if another USB device works on the USB port the UPS is connected to?

  • Help! iPhone 5 restarting by itself! Battery level won't change after charging.

    HELP!
    I have a 3 month old iPhone 5 that was recently updated to iOS 7. After a few days of use, I noticed after a night of charging, which I always do, the battery level indicator and percentage did not change. Next, in my carpool ride in to work, when using the iPhone, randomly the screen would freeze, then turn a random color and would shut off and restart.
    Then all of a sudden it was fine, no issues.
    Then today, the same thing is happening. The battery level, freezing/color changing on the screenscreen/restarting issues are back.
    I don't know whats going on. Never had an issue with any of 3 past my iPhones.
    Thanks in advance,
    Josh   

    I'm sorry, it seems that the problem is that my phone WON'T restore. I just tried restoring again and it keeps giving me the 2001 error. Help.

  • Magic mouse battery level

    My magic mouse battery level indicator doesn't seem to update. I view it under the BlueTooth menu, and can't seem to force it to reset.

    It's definiately a somewhat expensive convenience. I think the battery door on the Magic Mouse isn't designed very well, and makes changing / swapping rechargeable batteries more difficult than it should be. I've replaced the Mobee battery pack once after over 2 years of daily usage & weekly recharging. I'm sure there are less expensive options, possible even as convenient, but I received this as a gift, and I like it with the exception of not knowing when it's in need of recharge in order to get through my next session without having to fall back to a usb mouse. For what it's worth, that's my experience.
    Thanks again for the suggestion!

  • Accurate iOS Battery level using IOKit.framework

    Hi,
    I want to get iOS battery level for my app .Using UIDevice batteryLevel not able to get the accurate battery percentage.Just got to know that we have one public framework called IOKit.framework (which is available in "frameworks" folder so I am assuming it as public framework). Can I use this framework to get the battery level .
    In web, there are lot of talks that this is kind of private framework.so dont use it.Can we use this framework to create appstore iOS app.
    Thanks,
    Sakthivel

    What's wrong with the battery level indicator built into the iOS. Turn it on in Settings.
