I'm still using a Note 4. User-replaceable SD card, user-replaceable battery, wireless charging, good camera. Until someone decides to make a phone that has these features, or comes out with something earth-shattering, it's what I plan on using for the foreseeable future. I even have a spare Note 4 I picked up from the office in case this one dies.
It was starting to feel laggy/sluggish, so this week I backed up everything, did a factory reset, put a brand new 64GB SD card in it, restored everything and it's running like a new phone again. Night-and-day difference. Having 8,000+ photos on there probably wasn't helping things either.
