true... but for phone hoarders like me, that's not a good thing. I've never sold old phones. I still have my Note 2, Note 3, Note 4, S3, S4, S5, Droid Charge, Galaxy Nexus and Galaxy Fascinate.(all Verizon phones) When one of them has a battery that goes bad, I just buy a spare battery and it's as good as new within 10 seconds. I currently use Note 5 daily with the S6 as a back-up that I keep in the car. Guess if those two batteries go bad, I'll either have to toss them in the trash or pay Samsung to replace the batterie$.
