I have a Xiaomi Mi Mix 2 with 60Hz IPS LCD display so I guess that wont be a big bummer for me. The screen on my Mix 2 is a very good panel and colours are very close to AMOLED levels.I will say the battery & thermals situation is worse or similar at best with S21FE. NP1 is better for battery life because of S778, fabbed at TSMC not Samsung.
S21FE vs S20FE - both are almost the same phone with slightly different design but former has a Exynos fabbed at Samsung vs latter has S865 fabbed at TSMC. Generally chips fabbed at TSMC have better efficiency. Same can be seen in SD 8 gen 1 vs SD 8+ gen 1.
There are no other upcoming compact phones. Pixel 7a is coming soon, but will have an Exynos rebadged as Tensor SoC (same as Pixel 7). 7a will have a 90Hz panel though. 6a is a good choice if the camera is a priority & if you aren't jumping from a phone with a high refresh rate screen (as 6a has a 60Hz panel).
I guess, I should get a Pixel and get over with it.
Will moving to an e-SIM be problematic ? As I need a phone with 2 SIMS
