There can be large variations in how a 3 year old battery has been used. Apple Menu > About This Mac > System Report > Power will give you information on how many cycles the battery has been used, its condition and charge capacity.
yes it have 120 cycle charge and it is normal i have one question while on web and i click a video is it usally lose 2 percent in battery life and the charge capacity is normall
Since you have 120 cycles on a 3 year old computer you must use it plugged in more than you do on battery which can be bad for the battery. Apple recommends that at least once a month or twice a month you unplug it and use it on battery. Don't fully discharge the battery, which is also bad for battery health. I usually take mine down to 20%.
For a 3 year old Air with a battery in good condition I'd expect more than 3 hours but battery life does vary depending on how you use it. Watching video with the backlight up high is going to drain the battery faster than word processing with the backlight set low.
