Here’s what the Apple product page says regarding the battery life for its wireless keyboard, trackpad, and mouse:

A full charge is completed in about 2 hours, and provides enough power for about a month or more of usage.

My Magic Mouse 2 seems to run out of battery all the time, so I decided to track it between charges. It died on November 2 and then after a full recharge it died again today. That’s right at a month. I’m on it all day, 5-6 days per week, and I don’t turn it off at night.

A month of battery would be great if it weren’t for the fact that the lightening port for recharging the Magic Mouse 2 lies underneath it, which means you can’t use it while it’s recharging. And it always dies at the most inconvenient times.1 As a result, I keep my old Magic Mouse on hand, which takes two AA batteries, and I use it for about two hours once a month. Every time my new one is recharged and I switch back to it, I smile. It’s truly a superior mouse and more enjoyable to use, other than for this one hassle.
