Current minimum render distances are too high for lower end devices. I believe it should be left at 2 chunks for everyone as it was before. I tried to change it by editing options.txt but the game restores it to a fixed minimum. My tablet is locked at minimum of 6 chunks, my phone is at 4. Both are overheating badly with those defaults (I live in a tropical country). Also, playing on the go becomes difficult as battery consumption increases with those values.
