After this whole mess with batteries exploding in both Samsung and Apple smartphones, not as often but it has happened including one Iphone 6 "iPhone explodes and catches fire in a student’s back pocket", I realize that it's the non user swappable battery that's exploding in both the newer models of both companies phones, Samsungs Galaxy 4 and 5 both have user swappable batteries but the 6 and up are just like most of Apples phones the battery can not be easily replaced by the ownder, the problem with the older 4 and 5 is they don't offer the features of the newer models, but knowing what I know I can't bring myself to consider upgrading, would you trade newer features for potentially a phone that could catch fire?
