Reposting since I put it in the wrong thread:
Since everyone was arguing about how long it takes to install, I thought I’d document mine. iPhone 16 Pro, coming from beta 4 to beta 5, OTA update via cellular. I started the process at 1:24 pm.
1:24 — backup started
2:07 — got impatient, restarted phone, backup failed
2:09 — OTA download started
2:13 — preparing update
2:39 — preparation completed
2:40 — installation started (restart, apple icon, progress bar)
2:47 — installation completed (phone restarted, back up and running)
