Which laptop would you recommend for university use with battery life as the main priority?

I'm looking for a laptop that can handle IT-related tasks and some light gaming, but won't die after 2 hours without a charger. If anyone has other suggestions in a similar price range, feel free to share them.

What i found in my price range:

1. Dell G15 – i5-13450HX, RTX 3050
2. MSI Thin 15 – i5-12450H, RTX 2050
3. Lenovo IdeaPad Gaming 3 – R5-5500H, RTX 2050
4. Acer Nitro V 15 – R5-7535HS, RTX 2050
