How good is Oneplus Nord 3 today?

Hi, I was thinking about buying a Nord 3, looks like a great value for money. I wanted to know from someone who has had it for a long time how does it perform after months of use. I am mostly concerned about two things:

• Battery life: someone says it's good, someone says it's bad. I don't use heavy apps, I don't play games, should I still be worried about it?

• 4K Videos: on youtube I noticed 4K videos 30 fps don't have EIS. Was it added by some update? If not: anyone who uses gcam, does it solve this problem?

Thank you.
