The Google Nexus 6P was an excellent phone, until it developed severe battery issues when it was about a year old. Google did me the courtesy of replacing it with the Pixel XL, which was a reasonably good phone until two years in, when it developed moderate battery issues which were worsening rapidly.
My first cellphone was insanely expensive: the phone was expensive, the airtime was expensive, and the voice quality was awful. It was large and heavy and needed to be plugged in about every other day, even if I had not used it. My workplace bought it and issued it for me and I was stupid enough to accept it as a 24/7 leash.
