Photos app stuck at 35% while optimizing library on iPhone 16


My photos app says I haven’t optimized my library yet. It has been stuck on 35% for several days. I have tried restarting my phone many times and make sure to plug it in. I have tried everything I can think of. My phone (16) keeps telling me to optimize my library but I can’t.

Force Restart your iPhone:

  • Press and quickly release Volume Up
  • Press and quickly release Volume Down
  • Press and HOLD side button until the Apple logo appears. This could take up to 15 seconds and you must ignore anything else you see on the screen until the Apple logo comes up. If you do not see the Apple logo, try again as it may take a couple of attempts to get the speed and sequence of the button presses correct.

What does it say when you tap the ID icon ?


How much free storage do you have in your iPhone? How much in iCloud?


Have you tried a forced restart?

This is different from a simple Power Off. I had to continue holding the button down past the "slide to power off" message, and then I released the button only after  the Apple Logo appeared indicating a re-start.
