Myth. 100% sure that if I restore a backup, like I previously did, my phone will be the same in every aspect. And it’s about data speed, iPhone uses NVMe, which is super fast with that. We are not in 2005 with HDD. And you don’t have any 100% method to prove me that index is a thing nowadays. Again, you’re wrong. If my backup was around 30 gb and my iPhone nvme couldn’t read and process that in 1 hour or less, I would just sell the phone, it’s a nvme after all, super high speed in reading and writing 😉
