Purely anecdotal but I accidentally fell into this during university when studying for final exams. 3 hours sleep at night, 3 hours in early afternoon. Was great and never felt better so tried to keep it after exams but it was just impossible. Once I got back to real life, it was impossible to keep such a rigid and inflexible system. I didn’t do it long enough to see any long term effects but just found it impossible to keep anyway so naturally reverted back to 7-8 hours overnight
Pretty snappy. There’s no bloat at all and you’re in full control on what’s on there so it’s been quite nice. I haven’t noticed anything being slow. The default launcher is very like an iPhone but I would’ve always switched to lawnchair and put as many foss apps as I can for all the usual stuff so the experience day to day is very similar to my old phone at less than half the cost new.
