Remember that more ram is not equal to better performance, only when you run out of it.
As for storage i doubt you will ever go close to 64gb. And if you do you could super easily move your images and videos to Google Drive or Dropbox.
A few months ago my quick charge stopped working, i strangely might up fixing ut by reseting my phone. However a few days ago it went away again and im back to charging my phone in 3 hours.
But thats not all. For almost a year i have not been able to transfear files from my computer to my phone...
