Apple Wireless Keyboard Battery Life?

Stories about short battery life of the Apple Wireless Keyboard were present for some time, and Apple provided a firmware upgrade that apparently fixed the problem.

However, even after applying the patch, my Wireless Keyboard seems to drain the three batteries a bit faster than expected.

After several replacement cycles, I was just curious and measured the voltage of the drained batteries. The meter showed 1.3V. A bit too high for a drained battery. I also measured a drained battery from the Logitech M555b Bluetooth Mouse, and it showed only 1.0V, closer to the expected value.


I currently have no idea where the problem is, if it is related to the particular keyboard unit I have, or affects all Apple Wireless Keyboards.

On the bright side of things, at least this explains why the keyboard failed to operate with NiMH rechargeable accumulators (they are below the 1.3V threshold). And also, when used together with the bluetooth mouse, there is always the option to reuse the batteries in the mouse…

If you have an Apple Wireless Keyboard and you are not happy with the battery life, I would appreciate if you could measure the voltage of the drained battery and post the results below.

Aug. 2011 Update

This spring I bought a new Wireless Keyboard, this time Model Number A1314, Rated 3.0V. Compared to the previous one, labeled “A1255, Rated 4.5V”, the new keyboard requires only 2 AA batteries (instead of three), depletes the batteries below 1.3V, and in general has a longer battery life.

Based on this, my understanding is that the A1255 model was an early one, probably having some flaws, that were fixed in the further versions.

Final conclusions

The Apple Wireless Keyboard:

  • is identical to the laptop keyboard, so user that switch often between laptop and a desktop keyboard have absolutely no problems to adapt
  • if you use an external monitor connected to you laptop, it is the perfect addition in front of the monitor
  • has a decent battery life
  • in general is a great product!
Recommendations: be sure you have the latest version of the 3.0V  product, earlier (4.5V) versions may have some  low battery life problems.
