I just received my new laptop battery for my Asus N55SF, because I felt the old one drained too fast (for a while now, while running Windows 7, 8.1 and 10).

This laptop is 4 years old but still pretty fast and now running Windows 10, but since there are no compatible Windows 10 drivers, I installed the Windows 7 drivers instead. Now I'm wondering, since drivers also take care of energy management, will this guarantee that the battery will last about 3-4 hours? How long does your (preferably older) laptop last? How many minutes does it take for your laptop to drain 1 percent?

Windows 10 has its own battery management system that purportedly increases battery life. At four years old, your original battery should have lost a huge amount of its original capacity already - I've seen 4-5-year old laptops whose originally battery lives were 4 hours, and now down to 1.5-2. Your new battery should exhibit more battery life than the previous, in general.
