I gave up on it after Windows 10 sapped my battery life down to 3 hours once I opened a web browser. No matter what I did, the battery would run down once I actually started using it, even if I closed the apps. What with the ever increasing app gap, I said the hell with Verizon and Windows Phone.
Maybe in 2 years if the app gap closes, I'll come back, but I currently have a Samsung Galaxy s& Edge, and this is the most beautiful functional phone I've ever used. Even the apps that do exist are crippled and barely functional in many cases.
You sort of forget what the mobile world is like using Windows Phone for 2 years, but all of the apps, even the Microsoft apps work better on Android than Windows Phone. From Outlook, to Office, to OneNote, there is literally nothing that I miss about Windows Phone.
It IS a better OS, but the interaction between the apps and the OS just isn't there as fluidly and seamlessly as in Android (and iOS which I hate and will never use after having an iPad)
