I don't know as we haven't had it that long yet and he only wears it when we go out or are in a crowd, so we are still on original battery.

I'm not sure about hours because I don't wear mine continually. but my first battery lasted almost four weeks

It depends on the computer you're using it with, your screen brightness, whether or not you're on the internet, watching videos, have the volume turned up, etc. I get about 2 hours average, which is about 40% of the 5 hours I got on the Lenovo brand battery that came with my laptop.

From full charge, the battery typically will last 1-1.5 hours with continued usage.

I would say that 2 to 3 hours. You can buy the battery pack and go twice as much.

9 to 10 hours depending on setting and batteries used. I usually get at least 9 hours using rechargeable batteries.

I am going to say probably 4-5 hours on average if they get a good charge during the day. I now need to replace the battery in one of them, but I have had them for about 4 months. The others I have are still going strong.

Depending on computer settings, this answer can vary. I seem to get about 3 hours of constant use on my laptop when unplugged from a power source.

Operation time for standard batteries(6-cell, 4400mah): Around 2 hours, the actual operation time will depend on how much electricity is required by the device and how you use it.

Depends very much on what you are running. Using WIFI and doing typical work activities such as email, web browsing, word, etc., I have seen over 9 hours. If you're watching a movie streamed via 4GLTE the battery life does suffer. I have not timed it, but 6 hours seems pretty close under those contitions.

If you're not playing videos battery life can be up to six or seven hours, at high energy out put the battery life falls to three or four hours.

Up to 4 hrs, but it takes awhile to drain the battery. Everyday use for a week and still running in a single charge.

Battery life appears good, cannot say exactly how many hours but have used on highest volume for powered speakers. I would estimate 10 hours and battery is at 36%.

Usually around 6-8 hours. I've never had the battery die on a full days use.

Batteries last according to power consumption of usage. Anywhere from 1hr to 3 hrs depending on what your doing. Keep in mind that Core i7 processors draw more power when used at high percentage than most other processors.
