I did a search on your issue and didn't really come up with a great deal apart from this:
Some battery cells are shipped from factory in some sort of factory sleep mode. By Charging the unit 100% then letting the machine run on battery all the way down till it powers off (5%) repeat process 5-6 times should allow the battary to learn the full charge cycle and give you the maximum useage in hours (approx 4-6 hrs dependent on useage)
Just to add if the above doesn't work I would contact the place you bought the battery and explain the situation. You could also try posting in the forum I linked to above as other users of the same machine mat have had similar problems?
The problem neither was my battery, nor Windows.
It was just from Power Options as you see in the pic.
I was doing something else last night when I saw this option and found that's the reason of my problem.
Thank you @kemical for searching a lot and answering me.
