This is art. I much rather watch these videos to learn about my phone than others that burn, scratch, bend, and drop the phones for absolutely no reason. No one treats their phone like in those useless videos. Fantastic job with the teardown and I'm glad apple is moving towards the right direction regarding the right to repair movement.
Non soldered charging ports is probably one of the best improvements. I used to be a repair tech and that was always a pain.metal battery housing is for thermal dissipation I believe but also does happen to comply with eu regulations. I believe faceid components can be indecently repaired and calibrated now??
