The standby time is usually around 8 to 10 hours depending on how much the phone is used. Heavy use will probably result in only 6 to 8 hours of use.

I just used mine for 6 straight hours, and 2 hours the day before, still going strong. I would estimate 10 hours full charge to dead.

I use mine at work. I work 12 hour shifts and I have it on for about 10 hours and I can use it for 2 days before charging it.

Mine is good for about 4 hours. I guess it depends on how you have your laptop set up. I don't play games or watch movies, strictly read email and maybe hit facebook or pinterest.

I tend to just leave it all night charging, but I would say maybe 4 or so hours.

at least 2 hours. maybe even 3. Its been a year now and I still have 2 hours remaining in my battery and I'm a student. So i've been using my laptop extensibly.

It's a little difficult to say exactly because I listen to it on my way to work and back through bluetooth. I would estimate about 10 hours.

About 2 hours with activity, stand by is several hours. But after a few weeks of use, battery life goes under 1 hour. I plugged it in for 3 hours, and only 1/3 of it was charged. Really awful battery life.

4-6 hours, but mine only lasted a week and never worked again. Good luck with yours.
