Wireless Keyboard & Magic Mouse - Battery Power Reporting Problem

Problem Description: OS X Bluetooth Manager is constantly reporting that my 2009 Apple Wireless Keyboard has a low battery. For instance, Bluetooth Manager reports my Wireless Keyboard Battery Level is 18%. At the same time Bluetooth Manager reports my Mouse Battery Level is 65%. Because the Keyboard Battery Level is low I am being constantly nagged by the Bluetooth Manager about Battery Level and the possibility of the Keyboard disconnecting.
I decided to swap batteries between the keyboard and mouse as part of a test to see if there is a problem with the way the keyboard or mouse reports available battery power. Sure enough it appears there is a problem with battery power level reporting.
The batteries that were in the Wireless Keyboard, and that are now in the Magic Mous,e are now reported as having a Mouse Battery Level of 65%, compared to a Keyboard Battery Level of 18%. The batteries that were in the Magic Mouse, and that are now in the Wireless Keyboard, are now reported as having a Keyboard Battery Level of 18%, compared to a Mouse Battery Level of 65%.
Conclusion, either the Wireless Keyboard, or the Magic Mouse, or both devices are incorrectly reporting the Battery Power Level. It may also be that the OS X Bluetooth Manager is incorrectly reporting the battery level of one or both devices as well.
This needs Apple to investigate & fix the issue through updates to either the Magic Mouse, 2009 Wireless Keyboard or the OS X Bluetooth Stack.
I am using Duracell NiMH 1.2V 2000MAh "Stay Charged" Batteries (same as the Apple Store battery version)
I'm running Snow Leopard 10.6.4 + Apple 2009 Wireless Keyboard Firmware Update 1.0 + Bluetooth 2.0.1. Firmware Update.
So Apple Support Techs... there is the challenge; are you up for investigating and fixing this problem??
Cheers Pete

Thanks for the link David. I used the Community Forums because I've found in the past that Apple Support do monitor them and do pick up problems with Apple gear and pass the info back to their developers. Mostly I used the Community Forums because I just couldn't find the link you provided, so thanks again.
ps Apple & Macintosh are one in the same. My Apple Wireless Keyboard & Apple Magi Mouse are actually performing as per the descriptions in their respective user manuals, especially in terms of how they report battery state through their built in LED lights. So I deduced this as a problem with the Mac-mini Bluetooth Stack, so beleive it is appropriate to this forum.
I'm sure other users have noticed this, or similar problems, so perhaps they will add their experience of this issue to my original post. When I did a search of the Community Forums using the search term "Keyboard OR Mouse AND Battery" I found plenty of similar issues.
Thanks again for the link I'll chase Apple through that channel.

Apple Wireless keyboard/Magic Mouse battery levels differ

I have an iMac 27" that my Wireless keyboard came with and a 15" 2.2ghz i7 Quad and go between using both the keyboard and magic mouse with both of the machines.
However on the iMac the new keyboard shows 40% while the MBP shows 67%
the mouse is the same.
Magic Mouse on iMac is 87% and the MBP 100%
a few weeks ago before i picked up the rechargable battery kit from Apple, i had duracell batteries in the magic mouse and it said 100% for weeks straight which never made sense then randomly said there was 6% left and prompted to replace the batteries.
is this a hardware issue with the MBP bluetooth or just some glitch in software?
the iMac is 27" fresh out of the box 10.6.4 while MBP was updated using the 10.6.7 for MBP update.
thanks,

Hi Frank:
The battery reading anomaly is a known problem (began with OS X 10.6.7) and has been reported to Apple through channels. As an aside, I use the mighty monitor widget which seems to give correct readings.

HT3964 Apple Wireless Keyboard & Magic Mouse Not Working

i've been using Apple Wireless Keyboard and Magic Mouse on the iMac since Sep 2009 and they both worked well until one month ago, after cleaning the wireless keyboard, some of the function keys on the top row didn't work anymore while the magic mouse couldn't scroll left/right. it's really frustrating. how can i resolve this problem?

Handcream - Miscoloring on Wireless Keyboard/Magic Mouse?

Hi folks,
this question might sound a bit peculiar but I've tried to be as specific as possible:
I suffer from eczema and regulary need to apply cream on my hands - somewhere between 15-20 times a day. I use my MBP on and off the whole day and sometimes the whole evening as well. A few weeks ago I started working using the Wireless Keyboard (latest model) and the Magic Mouse.
When applying the cream I wait a few minutes untill the skin has absorbed most of it, but it is nearly impossible to work without some "leftovers". (Don't know the wright word for it).
So I'm wondering if the cream could have a damaging effect on the WK and the MM? Or maybe some miscoloring?
(I've used these products for a few weeks now and there is no miscoloring so far. Neither has the MBP been miscolored and I've used it since spring 2007. The only cleaning products I've used for the MBP is a cloth and plain water (The tapwater where I live has low levels of chalck in it - I think the term is soft water).
But since the WK and MM are made of different materials they might react differently?
Im sure there are others worrying about something similar. So; are there any dermatologists/doctors/scientists in here?
Im not looking for alternative solutions like wearing gloves, switching to a proven "safe" cream, etc.
Here is a list of what the cream contains:
Aqua
Tridecyl Stearate
Neopentyl Glycol Dicaprylate//Dicaprate
Carbamid
Ethylhexyl palmitate
Tridecyl Trimellitate
Ceteareth-20
Cetyl Alcohol
Stearyl alcohol
Butyrospermum Parkii Butter
BHT
Retinyl palmitate
Cholecalciferol
Phenoxyethanol
Caprylyl alcohol
Imidazolidinyl urea.
Puh...
Let's see if anyone can crack this;)
Thanks in advance!

Hello:
Go to system preferences>bluetooth>advanced. Be sure "allow Bluetooth devices to wake the computer" is checked.
I would also reset the PRAM and SMC.

Apple Wireless Keyboard & Magic Mouse reagieren bei Windows 7 Installation nicht

Guten Abend,
wie schon im Titel steht, funktionieren sowohl die Tastatur und die Maus bei der Windows 7 Installtion nicht.
Ich habe auch schon probiert die Installation mit einer USB-Maus und einer USB-Tastatur durchzuführen, jedoch ohne Erfolg.
Die Partitionierung und die Erstellung des Windows 7 Bootsticks mit Boot Camp hat ohne Probleme funktioniert.
Ich habe auch versucht Windows 7 mit einem externen DVD-Laufwerk zu installieren. Hat auch nicht funktioniert.
Ich habe einen iMac 21,5, late 2013 und will Windows 7 64 Bit incl. SP1 installieren.
Parallels kommt für mich eher weniger in Frage, da ich auch Spiele installieren will.
Über Tips und Hilfe würde ich mich sehr freuen

You need your OS X DVD and the files off there AFTER you install Windows.
You do not want "off the net" other than Apple.
And with Boot Camp 3.x you will then find updates to 3.1 and 3.2.
Windows 7 installer does not include the necessary graphics or Bluetooth drivers for your Mac.
Check Windows 7 Install FAQ with link to a set of drivers (not the ones from Boot Camp Assistant, that feature is BROKEN and has never worked when it was included in 10..6.6.

What's going on with my wireless keyboard and mouse power status?

My iMac (Nov. 2009) came with the wireless keyboard and mouse. When the original batteries wore out, I started using rechargeable batteries and that has worked fine. This is Energizer recharger, not Apple's. I've used and recharged them for well over a year now. When my batteries are freshly recharged, my iMac tells me I have something like 75% charge.
Earlier this week I'm being told that the batteries have 100% charge. They've never been 100% charged, even when they were new. I haven't charged the batteries for several weeks either when suddenly I supposedly have 100% charge.
What's going on?

This is a change that occurred with the 10.6.7 update. Everyone suddenly has 100% charge when other tools report less. Either it's a bug or they adjusted the scale by which it's measured. Some users report that the percentage starts to decrease after the battery is more depleted.
There's a widget you can use in dashboard in the mean time. Located here:

We'll wait and see if this is a bug or intentional.

TS3048 My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

I would always have a wired keyboard and mouse on hand (need not be expensive ... any cheap wired devices will work). "Emergency recovery" procedures can activate features in random order, so the opportunity to select a recovery partition may pass before the wireless devices are recognized.
That will let you select the "turn on Bluetooth" icon.

Is there available for iMac OS X version 10.4.11 700 MHz Power PC G4 a wireless keyboard and mouse combo?

Is there a wireless keyboard and mouse combo anywhere available for iMac OS X version 10.4.11 700 MHz Power PC?

All the keyboards I'm finding require built-in Bluetooth, something G3 iMacs don't have. So you'd need to start with a Bluetooth USB adaptor like this:
http://eshop.macsales.com/item/IOGear/GBU321/
Its specs says it works with Mac OS 10.3.9 or newer. The you should ba able to add a wireless board and/or mouse IF you find one that has support for a Mac OS level older than 10.5 or an Intel processor. Most current boards require 10.5.8, and Intel processor, or both.
The cost for all this could easily be 4-5X the used market value of a G3 iMac so please think this through carefully. A long USB extension cable might be a better option fo such an old computer.

Apple Wireless Keyboard and Mouse + Bootcamp = screensaver problems

I can't seem to get the screensaver to activate when using the apple wireless keyboard and mouse under windows XP with Bootcamp.
I know its a problem with the wireless devices because if i restart the computer and not press anything (ie. mouse or keyboard) then the screensaver will work.
However as soon as I press the mouse or move the cursor around, the screensaver will fail to activate on its own, or if it activates, it will wake itself up even if I don't move the mouse or press the keyboard.
Any solutions?

Hi Capfred: Thank you for your replay. I have tried to follow your information but unable to solve the problem. I followed your comments but I am unable to get to the menu you mention. I have installed MAC OS X, Version 10.7.2 .
The only thing that works is the Apple last wireless mouse. I belive that I must have done something that created this situation. My problem is that I live in Panama, Central America and the local Apple dealer has little to no tech support.
Would it be possible for me to call you and review the config of these items or is there a way to restore the Macbook Air to the original installation .
I appreciate your kind help and once again thank you for your help. Regards,
Ruben

Magic Mouse battery usage

I've come to the conclusion that the problem wt the magic mouse battery usage is not completely that it uses to much power (scrollng seems to kill it), but that it instead warns you way to early about shutoff. When it does shutoff, by just clicking the mouse, it will come back on. If my battery was truly departed, then how could it come back to life, show 5% power, and then operate for literally hours, before going off again. Off course you have to hear that annoying ping, and then have to click on the message stating that your mouse will soon turn off. I love my magic mouse except for this technical glitch. What I would like to do, is write a script, to remove all battery warnings, and possibly make it so the mouse doesn't turn off, until it is truly at 0% power, but I am not very technically oriented.

Hello Apple Discussions,
I am a brand new Magic Trackapd user (since 13th of August 2010), but I already noticed something strange. My battery power dropped from 100% to 89% for less than 4 days of continuous usage. My trackpad has been delivered with Energizer Alkaline batteries.
Here's my battery life story.
Obviously, days between battery changes depend on use. I started with Alkaline batteries (Duracell) when I got the MT (Magic Trackpad) working. Battery life was about a month on the first set. I use the trackpad exclusively (of my three different devices- Magic Trackpad, Wacom tablet, Logitech S530 wireless mouse+keyboard) now, on my desktop MacPro.
I am now trying the Sanyo brand Eneloop batteries to compare. I didn't even notice the battery warnings until the screen flashed a battery low indicator. I also have been using two Eneloop's in my Logitech keyboard, with I think, excellent results (about three months of constant use, and the charge indicator does gradually falls off in that time until blinking a warning).
When I first inserted the rechargeable batteries their charge level said 83%. So I don't know if the life expectancy of the rechargeables will be close to that of alkaline (which said 98% when first started). Certainly it's more economical to use rechargeables. I use the mouse a lot. I see in this thread that results vary from a week or two to months.
Questions:
Does turning off the Trackpad make a big difference compared with leaving it set unused?
Does a rechargeable give way lower life than an alkaline?
What is the comparable battery life between the types of power sources- Alkaline, Eneloop, NIMH, Lithium?
Is there an app for archiving battery life information on the MT? There is one for the laptop and there is history in Profiler, so it seems there could be a way to get the data. Has anyone done it?
Is the low battery indicator (1.0V??) a false indication?

Magic Mouse battery only lasts 30 days?

I bought my new 21" iMac back in October and today got a message from Magic Mouse that batteries need to be replaced.
What kind of battery life other folks are getting from MM? Is there anything can be done to increase battery life of MM?

Hi Kenichi Watanabe:
Would seem some Apple reference reported the Magic Mouse batteries should last four months. I've only found items that report the reference (have not located the reference itself). Clips below are cross posted, but if you search the Internet for the terms ["Magic Mouse" four months] (without the brackets), you'll find a whole series of early reviews and comments containing the same reference to four month battery life.
Perhaps inquire directly of Apple Care. Gizmodo's review (http://gizmodo.com/5386202/apple-magic-mouse-review ) relays a claim about the Magic Mouse battery life saying, "it's powered by two AA batteries, which get up to four months of use per charge, according to Apple."
Engadget's preview (link follows) included the same reference, the related headline read, "Apple's Magic Mouse: one button, multitouch gestures, Bluetooth, four-month battery life."
http://www.engadget.com/2009/10/20/apples-magic-mouse-multitouch-gestures-blueto oth-four-month/
Finding support for Gizmodo's reference ("according to Apple") and Engadget's headline may be a little more difficult. Perhaps I haven't read the press release carefully enough. Clip below, from that Apple press release:
"Apple Introduces Magic Mouse," press release, 20 Oct 2009, Apple.com (http://www.apple.com/pr/library/2009/10/20magicmouse.html : accessed 24 Nov 2009), in part, "Magic Mouse uses Bluetooth wireless capabilities to create a clean, cable-free desk top and its secure wireless connection works from up to 10 meters away. To extend battery performance, Magic Mouse includes an advanced power management system that works with Mac OS® X to automatically switch to low power modes during periods of inactivity. The wireless Magic Mouse is powered by two AA batteries which are included."
Hope this helps

Magic Mouse battery drain since updating to 10.9.5

Since updating my iMac to 10.9.5 my Magic Mouse battery life has gone from over a month of use to less than a day. It's so bad I switched back to a USB based Mouse. Has anyone else experienced a rapid battery drain of their Magic Mouse since updating their iMac?
Ian

Hello Ian, I know it sounds simplistic but you will have to check the battery situation. Here are a few notes I recently made. It is true that Mavericks needx more memory support but probably it's not much more of a drain on the mouse batteries.
Whether you use regular or rechargeable batteries you should buy the best. Discounted or unbranded batteries are more likely to give a depleted performance and may be of irregular size, often leading to connection problems. Apple’s own brand, Eneloop and Energiser appear to be the best.
Rechargeable batteries for the standard Magic mouse are unlikely to exceed eighteen days before needing a recharge although the mouse itself can be a limiting factor. I have seen reports that some Logitech mice vastly exceed this. Apple may suggest more in their sales blurb but this is a realistic expectation. The benefit (if you are organised) is that you can always have charged batteries available. Regular batteries will give you between 25 and 35 days before they need to be replaced. Note. Never mix old and new batteries or rechargeable and regular.
The notes above are based on my personal experience, not shutting down my machine and using it for around four hours per day. Note. Monitors do not always faithfully report battery strength, particularly the rechargeable ones.
When checking your mouse or keyboard batteries ... Turn off the device. Remove the batteries, Clean the terminals both inside the battery compartment and the batteries themselves. Replace or renew both batteries. Turn on the device. You should get a blinking green light if the device is paired. Click the mouse to activate it. The green light becomes steady.

Does VM Ware Support Apple Wireless Keyboard and Mouse

I downloaded VM Ware from Apple.com. I got to my Windows XP Home login screen, but I could not move the mouse to login to the XP Computer. I had to restart the computer by holding down the power button because I was, "stuck." Does anyone out there know if VMWare is compatible with the wireless keyboard and mouse? I'm using Leopard and Windows XP Home SP 2.
Thanks,
David

New wireless Keyboard with terrible battery life

Is this how they all work?
I recently bought a wireless keyboard for my mac mini that's in a closet functioning as a media server. It seems that the battery life is terrible. I used the keyboard for about one hour one day and didn't touch the device for two weeks. After this two week interlude the batteries were dead. This is the 2nd time I have noticed this.
So should I remove the batteries when not using the keyboard. I can't seem to tell if the keyboard is on or off by pushing the button since the keyboard light doesn't stay on when in use.
I have other wireless keyboards that seem to have battery life that go and go and go

One Possible EXPLANATION For Apple Wireless Keyboards Or Mice GOING THROUGH BATTERIES In A Matter Of Weeks is as follows:
When you shut down or sleep your Mac, if there is a second Mac running at some distance away (up to 100 meters distance), and this distant Mac has bluetooth switched on, and was, for some reason, previously been paired with your wireless keyboard or mouse, then I believe the keyboard or mousewill try to link to the distant Mac after you have shut down the local Mac, using all its available transmission power to overcome the distance, and thereby wearing down the batteries.
This happened to me. I have two Macs in the house, and paired my new wireless keyboard with both computers, just so that I could use this keyboard with either Mac.
But when I shut down the Mac I was using, without me realizing, my wireless keyboard that I had in front of me would then link up to my other distant Mac (which was usually always running), located at the other side of my house, and in doing so, my wireless keyboard would wear out its batteries in weeks from the power drain due to long distance transmission and reception.
Whether this battery draining from long distance transmission and reception can also occur when the wireless keyboard or mouse has not been paired with the distant Mac, I am not sure. It's conceivable that in the bluetooth polling mode, where the distant computer is trying to link up to the wireless keyboard or mouse, there could also be substantial power draining from long distance transmission and reception (especially if bluetooth is set to discoverable).
Someone may want to test this: seeing if bluetooth polling over distance can drain power. Who knows, it may be that your neighbor has a Mac, and so when you switch off your computer, your wireless keyboard or mouse spends all night trying to link to your neighbor's Mac.
