Non-removable batteries are all about building obsolescence into phones and time constraints before the next model release. Engineering takes time, parts sourcing, building, testing, spares production, etc. Anytime you want to release something new, time constraints is your #1 enemy. Samsung is also touting IP specs with their phones, (the new "big" thing), and having a removable battery, along with these specs, is not a good thing. So... they're sacrificing the battery, and at the same time banking that customers will grow to accept it. They tried it with the SD, and it didn't work, no matter the PR, or BS on this very forum, about how much better the internal memory was on the Note 5, and that you didn't need an SD, or that SD's are on the way out. Total BS! If you can refute this, then tell me why they're now pushing how great the Note 7 is at supporting 256gb SD's! Also, what's the word nowadays about the internal memory of the Note 7? It's a forgotten subject... lost with the Note 5... naturally!
It's not that they "can't" release the phone with a removable battery. It's not because there's no room, or they can't gain the style. It's because they don't want to invest money and resources in something they know will change in the next 10 - 12 months. Its all about money and Samsung is finding that a lot of customers are willing to put up with it. Samsung doesn't care about what customers want any more than any other manufacture. Cash is King! Sadly, the major point of Samsung used to be the removable battery and how you can be free of always having to plug into a charger. That philosophy... Where the heck did it go? Answer: Cash is King!
As for my usage, I cycle my Note 4 batteries every two charge cycles. Most of the time my major reason for swapping is only because I'm too lazy to sit and wait for my battery to charge, or I forgot to charge it the night before.
I tend to agree with the OP.
