You have to see if it is worth having 5G turned on in your case. It heats more and drains the battery
Have you done a 4G vs 5G speed test?
4G gives me 200Mbps Download and 40Mbps Upload and 5G gives me 500Mbps Download and around the same Upload
But why do I want 500Mbps? I only use social media. And even if one day I played something 200Mbps download and 40Mbps upload is more than enough.
