A:AnswerI’m not sure how long a single charge is supposed to last. I never check to see how much power is left because it’s designed so that you can use it and charge it at the same time. If I ever have one that gets low on power, I will just plug it in and keep using it. The charge seems to last several months. Running out of charge will never be a problem.
A:AnswerI regret getting the white one for work! You can definitely see the stains over by the thumb portion. It surprised me because I’m the type to wash my hands throughout the day, but excluding that, the mouse is amazing.
