devours up to 1 battery per day

The fact that it really is even so bad, I never thought. From the MX610 I was used to, with 2 batteries (eneloop) even times get along up to 6 months. The average was about 3 months. Also, there was no problem to bridge times with only one half full Battery 2 weeks. Unfortunately, the MX610 had with Logitech at the time usual click problem and after 2 or 3 years, it was then over. Buy Well and yet or has not been possible so had to spare her a year ago. Radio and it should be more than 2 or 3 buttons. So the Performance MX came ultimately to the desktop. She still looks good and the wear and tear are limited. But what more and more annoying since about a month is me the battery wear. At first I was surprised that the battery (has unfortunately only one) all after 2 weeks was. Meanwhile, it happens that I have to go after a day. I find that for today's wireless mouse - which is no Gamermaus - unacceptable. If Logitech has done it once before, to enable a useful life of 3 months, then why go back such large steps back. Even my Logitech Mouseman from around 2001 requires only 4 weeks to change the 2 batteries.

Of course I have the battery does not change even after 24 hours, if I'm not all the time on the computer. However, a gambler weekend for a mouse of the present generation should not be a problem. For the PC 3-8h per day within a week a full battery lasts just like this, sometimes a little more, but sometimes a little less. Nevertheless, I think during the exchange that I had inserted a new battery yesterday.
