How do you restore app data without usb & without root?

I have an s4 (rooted) and I usually use titanium for my backup/restore when I get a new device. I obviously can't do that (since there is no root yet on 5x) and I don't have a usb-c to usb cable so I cant do something like helium.

How are you guys restoring everything?

(androids built in restore is suck... it only did 8 apps, ha).
