All of that is wrong. People don't want dual wide angle camera because they never USED it before. Once they have used it, and use it daily, they'll want it permanently.
A second display isn't necessary but it was different and useful.
Battery case? You know how thick that thing is? It's like carrying a brick in your pocket. I'd rather have a small and flat external battery in my back pocket. Fast charging is good, but you have to be around wires still. Traveling out of town with no car? Gotta carry a huge battery pack connected to your phone with wires hanging out of your pocket.
Majority of people don't use their phones for music? I think not. Why did HTC remove the headphone jack? To improve audio quality via USB.
I record video all the time when I travel. You don't go on vacation? With editing software included, a laptop or desktop computer is not needed, yet alone expensive software. You must not have a social media page.
No one cares about IR blasters? Everybody uses a remote control everyday. It's still being used, not obsolete yet.
You are an average user that needs an average phone (iPhone, etc.). The V series is not an average phone, it's a feature rich flagship phone aimed at those that want the best possible phone.
