I have a dock and used that exclusively for at least a year after a friend's Z1 Compact had the same problem. It's mostly using my portable charger that has made me need to use USB. I suppose I could have bought a simple magnetic charger and used that with the charger, but I didn't think of that.
I don't like Sony's Contacts and Calendar apps, so I had to find apks for Google's ones and hide the Sony ones in Nova. There's also rubbish like What's New, Lifelog, Lounge, PlayStation Video, a poor message app, a not very good music app, and some camera filter things that are all wasted space to me. Especially in a 16GB phone. Also, in recent versions of the OS they've nerfed the stamina mode that used to exist and do me very well. I'm quite fussy about this stuff, which is why I was a big fan of my Nexus 4. If the digitiser in the navigation bar area hadn't died I'd still be using it today. That's why even with them not covering the ports now that the world has moved past early water resistance, I'm not really interested in going Sony again.
