If this is a sign of what's to come with the next Note then there's no chance of me upgrading. Fast charging won't mitigate the loss of a replaceable battery. The real reason behind a fixed battery is it forces you to junk a working phone once the battery won't hold a respectable charge. I needed a new battery after about 14 months with my note. Easy and cheap enough to replace it With the note 3 but what about this model? A couple of hundred bucks to replace it? I bet their helpful answer is buy an s7.
Phones are already stupidly thin, well beyond it conferring any advantage beyond poser value.
