I haven't had mine longer than a few months, but there is no need to turn it off after each use. You may wish to turn off if you are putting it away in your briefcase/backpack.

I turn it off when it is my bag, but if you are leaving it sit somewhere it will turn itself off without the switch.

I have mine for about 8 months and I never turn it off unless it goes a little querky and doesn't work right. The battery is still working fine. It goes to "sleep" when not in use so that saves the battery. But it use 2 aa batteries so they don't cost much. It is a great little mouse. I use it on my nook tablet.

Did everyone try charging the unit while it is powered off?It seems to make a different to me. I bought three(3) and so far all battery seemed to be decently averaged out around 2.5 hours or so (mainly net surfing and video conferencing) after few months of usage. Power on while charging seems like charges don't hold too well even it shows 100% charged.Try it out...it may make some different.

My first battery change was about two months in, and that's with heavy use and the screen/button illumination always on. I turned off the auto-on settings and stretched it out a couple more months. Of course, I use it constantly throughout the day and evening.

I don't have this answer because it has always stayed on for the short duration I use it then it either goes off while sitting idle or I turn it off. I do know it has a short idle duration before it turns off on its own but I'm OK with that.

I am a newbie too! I tend to shut my keyboard off when I am using my device as a tablet. There is a little lag time when I do fire it up to use the tablet/keyboard combo as a laptop, but it saves battery life and prevents inadvertent keystrokes etc. Hope this helps!

To switch on/off the device you need to press and hold the power button for some time like 5 secs. Otherwise, it considers to be a pause of played track and may take the battery life even when not playing. You don't need to put the device for charging for that long. I think some 4 hours will be enough.

Battery life has been great so far. I've recently switched over NiMh rechargeables for all of my batteries. Haven't had to recharge them for about a month. The mouse has an auto shutoff feature after periods of inactivity.

Well, unfortunately I'm not an avid gamer so I am not on it that often, but I have found that if you have it in sleep mode it does a very good job of retaining power. If I were to estimate, if you played it as much as the average owner, I would say you could get a guaranteed couple days out of it...I might even venture and say three days. Again thats just a guess.You might wanna poke around online and google some sites that will give you some good insight on the battery life. Hope I was able to help at least a little. Have fun and keep gaming! ;)

Hello Harold, I had never turn it off because in the user manual says that it turns off automatically, I have been using it for about 2 months and I did not replaced the battery as you mention.

I do not turn it off. It would save on batteries if I did. I've had to replace the batteries once. You will know when you need to replace them because the mouse will act funny.

The battery life is very good. I've been using it a couple of months now. I'm still using the furnished batteries. It has an on-off switch which would save on batteries even more, but I never remember to turn it off. It's very comfortable to use. I'm extremely pleased with it.

I feel like I have been using my current battery for at least 6 months. And I never turn the mouse off. I bought mine on 8/4/13 and can only remember changing the battery once. It lasts long enough that I don't notice it being a hassle, for sure. I love this mouse.

I agree w/others- don't wait to charge it, because when the battery dies, it turns off right away, there's not necessarily a couple minutes warning like most devices. My experience is that when it dies, give it an hour or 2 to charge & stick a pin in the back "reset" hole. I like my Le Pan, haven't really had any issues w/it, though the keyboard can be pretty slow & twitchy at times, Firefox crashes on & off, but that happens w/pretty much any device because Firefox can be unstable in itself.*typing this from my Le Pan :)

I've had my Lenovo since June and almost exclusively keep it plugged in. I used the battery a couple of times but only for a short period. So, I really can't comment on the battery life. However, I do understand that it's good for only 2 hours or so. I've read other complaints about that. Also, can't comment on the battery replacement issue. Sorry!

I don't have it in front of me, but I never turn it off. Hasn't drained the battery in a few months either. I don't even turn off the mouse. I speculate that it put the devices in some sort of power standby. I don't remember seeing a way to turn the keyboard off.

Well like every battery it depends on how u use it,since I got it which I think was January I've used it every now an then without having to charge ,I would recommend leaving it switched to off when not using it

Best to turn it off then charge it....don't let battery drain totally. I often use it plugged in when it's fully charged.
