I'm still enjoying my 2013 Nexus 5. The first replacement battery (2015) was a winner, but last year's was a dud. I wonder if the batteries sold by ifixit are any good? It began boot looping a few months ago, which I fixed with a factory reset.
I just got a battery from them for my 6p. It was the same model, but looked different. It was also sightly too large compared to the old one, and the circuit board was sticking out. I had to really cram it in there for it to work.
