Add a setting to adjust sleep timer. it will reduce battery life but just add a notice on the setting. On blue tooth the mouse goes to sleep in 10 seconds and then when you move it it jumps past where you want the cursor. It would be nice if I could change it to a 5or 10 min. delay. I have used another brand of blue tooth mouse on my lap top and it doesn't have the same issue but i like the size and feel of this one.
