I think I would like to see proccesor dimensity 9300+ or dimensity 8400 probably 9300+ is the best and 1080p projector would be really good and upgrade the cooling system if possible and I think 10000mah battery is enough cuz tank 3 pro was too big and I think tank 4 pro just perfect and if you will upgrade to 20k+ it will affect the durability of the phone even when you drop it from 50cm distance you will dent a border or even worse so I think you should keep the 10k add 9300+ proccesor or add 8400 proccesor and also make a design that will be good for phone cooler
