Ok I'd like to set up my phone as new (iPhone 6 bought in November 2014). Basically had some battery weirdness (larger than normal percentage jumps mainly and the impression of less usage). Just came back from the Apple store for the 2nd time in as many months. They said my diagnostics check out - battery is fine - as is the hardware. Think it might be a good idea to clean things up and "start over" so what do I need to do? This is my plan to prepare: 1)Took screenshots of every page and ever folder's page - hough I'll likely rearrange and not reinstall some apps anyway. 2)I backup all my contacts to outlook on my PC should be easy to restore. 3) Messaging apps. Will iMessage be restored? What about others like Telegram or Whatsapp? I presume it depends on the app? 3)Settings and passwords will need to be entered again - that's ok - I assume I'll have to setup touch ID again? 4)Photos, all backed up on my computer by habit (no iCloud thanks). Anyway to put them back on my phone after restoring as new? 5) Music. No worries about my ripped and iTunes or elsewhere purchased and downloaded music, I backup my iTunes library anyway and it will be simple, if time consuming to put it back. I wonder about my Apple Music preferences would I need to redo them or are they linked to my account? 6) Apps: well I’ll have to sign-in to some apps again etc. Some apps use iCloud or their own cloud backup so no problem. I don’t understand why apps can’t be backed up on the Mac or PC but anyway. Anything else I should be aware of?
