I am honored
Yes, i did balance all of them. Main remaining difference between the 3 phones is still:
- 1.1.7. phone is used since 07/14 by my wife and has some accounts and few diskspace, took an hour to balance.
-1.1.9. phone is from 09/15 and barely used, no accounts only updated in 5 steps and used as a tethering device.
-2.0.0 my main device from 01/14, factory reseted recently but nevertheless the one with most history.

But please do not expect to much from my first attempt. I even forgot to show version number of the phones as proof...
And i am not satified with "meaningfulness" of my test case.
Hope you will have an even better idea what to show @Ste-phan.
I may be doing another version after the first attempt with all phones facory reseted freshly.
