Question about Logitech MX Anywhere 2

approx. three and a half hours

The battery lasts about 5 weeks with average use and I don't even switch the mouse off! If I did that every time I didn't use it, the battery would easily last 2 months! The mouse can also be operated when it is connected to the charging cable. So if the battery dies, connect it to the USB charging cable and continue working!

For me, the battery lasts about two weeks with relatively intensive use. Charging is also very fast.
