The storage you choose is going to determine how long you can keep your phone for. I suggest always investing in the 256GB at least if you plan to keep your phone for 2-3 years. Anything less would give you issues after 10 months. ✨
This is the issue I experienced with the iPhone 13 pro max. I was constantly having to restore my phone to clear out space because the system data was eating through the 128g. After upgrading to the 14 pro max 256g, I haven’t experienced issues with storage.
You wouldn’t have have a problem if you back everything up to iCloud and delete what you don’t need. Unless your taking high res photos and cinematic videos then 128 is a good size storage to get
