I just purchased another battery too, thinking the one that came with the remote is defective or going bad. But it was not an improvement.

While I very much like the MX-950, I do have to complain about the battery life. Granted, I am a heavy user, but after the first dozen clicks (literally) the battery indicator starts showing ware. And I have to recharge 2-3 times per day. I also noticed that after a full charge the power menu shows 90% (which may be why the indicator goes down so fast).
