it is unbelievable how poorly optimized (or rather, unoptimized) ios26 is. refraction+extreme blur/transparency+HDR UI+ unoptimized LLM/ml on device100% RAM is the biggest factor for Apple devices as their A and M chips are beats for CPU/GPU.
That’s why for years apple were always behind android for RAM because prior to Apple Intelligence and Liquid Glass, the OS just didn’t need as much RAM.
