I work as a photographer processing lots of images and heavy files, my computer has never used more than 5GB RAM but well, facebook and instagram may use it though...who knows
Why only 16GB..go for 32 no 64 would be better and charge an extra 500$ for the RAM no one will ever use
Looking at the resolution, I'd take it with a huge grain of salt. 2080x1080 tells me that the aspect ratio is around 17.3:9, as close as the OG Mi Mix. Phones are getting even longer with the S20 series using 20:9 aspect ratio which is just too long. Then again, I could be wrong and I much prefer to have wider displays.
Also, if these specs are true, Xiaomi Mi 10 Pro is turning out to be one of those dream phones, ticking all the boxes of what makes an excellent device.
