Battery Performance 😠😠😠

There are three reasons why Samsung is behind some reason, for some reason, the first battery behind, the second speed, and the third software, Samsung 3 was behind, and will remain behind, not knowing when this 3 thing Will improve in Samsung ?? Made a little improvement but softwares and batteries fell into ?? Why do Samsung skimp so much in giving Samsung batteries? Like the headphones given to another company, by the way, the battery should be given to another company, so there is such a lousy battery. Do not ask in the Galaxy S8, so expensive mobile and battery is so cheap? It is so annoying that the heart is breaking the mobile slip, and buy Nokia's mobile? Because this Samsung will ever extend the performance of its battery in life, if Samsung does not improve it even after saying so, then damn it, on Samsung's wallet, I take it from Nokia's throw..😠😠😠
