I’m currently still rocking a 128gb iPhone 6s, decided not to upgrade to the 8/X when contract was up last year. Every time I upgraded previously I always went for the higher capacity available just to be safe and never have any storage issues.
But I have a “new” (used but fantastic condition) 32gb iPhone 7 that I could upgrade to if I want. So I’m currently trying to see if I could cope with downgrading my storage capacity. After offloading the apps I don’t use and deleting pics/vids I don’t need, I’m down to using about 28gb. I could gain a few more gb by utilising iCloud for the remaining pics/vids.
But even at that I’m still not sure if I wanna swap devices - do the upgrades outweigh the loss of storage
For both my iPad Air and iPad Pro I have 32gb variants and that is more than enough for what I use them for.
I have a few older external hard drives with about 4-5TB on them (movies etc) but I haven’t looked at them in years so could just as easy delete and get rid of them.
