Question about Lenovo Legion 7i

For me, only about 2 hours when surfing the web. I'm a little disappointed.

That is a difficult question. It depends on how you use it. I always have it plugged in when I'm gaming. In general, I can say that the battery performance is worse compared to my second Lenovo work laptop (T490s). It's a high-end gaming laptop and it doesn't replace my work laptop in terms of battery power, weight and keyboard.
