It’s not exactly the most scientific test ever conducted, but a very practical experiment conducted by Softpedia’s Filip Truta reveals that the new Apple Magic Mouse pales next to its predecessor in at least one significant way. That area of weakness is power management, and the new slick interface device could be as much as 40 percent less efficient than the clumsy old Mighty Mouse.

Reports have been flooding in that the new mouse is a power-hungry little guy, both internally among staff here at TheAppleBlog and over at the Apple Discussion boards. At least one discussion thread deals with the problem that the Magic Mouse has when working in conjunction with the Apple Wireless Bluetooth Keyboard. Apparently, using both together will result in significant battery drain in the latter.

On its own, the Magic Mouse is no energy superstar either. Many users report a much shorter battery life than they got with the Bluetooth Mighty Mouse. Truta was finding the same thing with his new pointing device, and so went about testing his theory to see what he found. Rather than timing the life of the batteries during regular continuous usage, as a lab might, Truta came up with an easy to perform exercise that you can try for yourself, too, so long as you’re in possession of both models of Apple mice.

The trick is to use a fresh set of batteries in the Magic Mouse until they run out of steam. Apple’s redesigned the mouse preferences pane to tell you when you need to change them, and even provides instructions on how to do so in case you can’t figure it out for yourself. Once the batteries are depleted, all you have to do is switch them back into your old Mighty Mouse.

Using this very simple method, Truta discovered that while the Magic Mouse saw the batteries as devoid of anymore usable energy, the Mighty Mouse would in fact report that the batteries weren’t even close to empty. In fact, his tests show that under the Bluetooth devices menu it would report as much as 41 percent battery remaining in the supposedly dead batteries. That’s not an insignificant margin by any count.

Battery issues aside, I sill love my Magic Mouse. I should qualify that by noting that I use it as the primary means of control for my home theater Mac mini, which means that I use it quite sparingly. I’m still using the same batteries I put in when I got it, which was almost immediately following its release. And my keyboard doesn’t seem to be running down with any unusual speed, either. But again, I almost never use them really, except to set up a movie or TV show or start a playlist in iTunes. I’m still planning on testing out Filip Truta method when the batteries do eventually run down, though. What are your experiences?

  1. After 1.5 months with the 27″ iMac,

    Magic Mouse: 35%
    Keyboard: 92%

  2. My first set of batteries lasted over a month with daily use, and never turning off the mouse.

    Now I’m using the same rechargeable batteries that I used in my previous Logitech mouse. I did notice that they were a bit heavier than those included with Magic Mouse, but I’m used to it now. In a bit over 2 weeks they’ve decreased 30%. Not bad again for daily use and never turning the mouse off.

    Since I have 8 rechargeable batteries, I have no problem in switching them out every other month. All in all, I love the Might Mouse. Though, I do wish it had the zoom gesture.

    Another Apple mouse that isn’t cutting it with the most basic of expectations? Say it isn’t so.

    Rick, do you think it’s a matter of all the features being a drain… or is it power consumption overall? Just when I thought there would be a saving grace after the mighty mouse it still seems like my Logitech G7 is the ugly but ergonomic workhorse.

    1. Not sure what causes the extra drain.

      I still don’t see the big issue with investing a minimal amount in some rechargeable batteries and swapping them out every month (my original comment said every other, which is prob too generous). I’ve been using the same rechargeable batteries since 2006.

  5. My first set of batteries lasted 8 weeks (li-ion) and am now on my second set 10 days in and pref pane reports 100%, Had a Mighty mouse before and it got about 8 weeks per set of li-ions, so I’m happy!

  6. Since I got my new 21.5″ iMac new back in October:

    Magic Mouse: 77% second set of batteries
    Keyboard: 89% original batteries

    My mouse does use batteries quite quickly but nowhere as quick as some people are reporting.

  7. Is it so hard to buy a few rechargeable batteries?

    The new mouse has multi touch, that MUST take more power then having no multi touch.

  8. Received new 27″ iMac on Dec. 7 and am currently on my second set of batteries. Always on, never turn them off. Use 6-7 hours per day. Not unhappy with this performance. Ask me again in a year…

  9. For me, my wireless keyboard was going through a set of batteries about every four months.

    When I got the Magic Mouse there was 87% power left in the keyboard and 100% in the Magic Mouse.

    Five days later the keyboard is at 54% and the Mouse is at 75%. Not good at all. Looks like I will be changing the keyboard batteries almost weekly from now on.

    1. Almost weekly?? It seems more practical to change bi-weekly. If not, send me those 50% batteries you swap out of the keyboard!

  10. I have had my 27″ iMac Quad Core since December 1st.

    Here are my stats:

    I use it about 3 hours every day. For work and during leisure time.

    Magic Mouse = 67%
    Apple Wireless Keyboard = 100%

    If you do not believe this, I got this off System Preferences. So I am actually satisfied with the battery life of these two products.
