If u are only using it 4 hours then try to charge it, it might not charge since the batteries are still fully powered. Only when your mouse light is blinking green then its charging.Originally posted by: BoomAM
Upto now, ive used it about 4 hours a night, cos ive been at college, and when i put it back in the charger at night, it "says" its recharged almost the moment that i put it on.
Either is a very fast charger, or it didnt use much power within those four hours. Great mouse though. Amazingly comfy.

I tested my MX700 the same way as you did. This mouse eats batteries!!! The first time useage after fully charged lasts only 2 days. I used it about 10 hours a day. Then I recharged it and used less time per day and it lasted only 3 days. I checked the information of this mouse, logitech says a "normal" user can use it for 10 days after fully charged. I don't know how many hours are "normal".
After these two battery life tests, now I only use the mouse during daytime and put it back to the cradle at night.
