Perform better or simply last longer?iphone 5 with iOS 6 easily lasted 10 hours while the iPhone X barely last 7/8 hours and that’s with OLED screen and advance CPU and bigger battery?????
12 hours since unplugging maybe. No way is that legit usage. Most iphones would be dead in less than 12 hours of usage, assuming it wasn't all music played in the background.My X probably sits at about 80% left after 12 hours of use so it is a lot longer than 10 hours
True, compare the same form factor and everything with better internals to see the improvement.The biggest battery killer is generally the screen (unless some app is bad and keeps your CPU running high), and the screen has got bigger since the 5s . They have also been added more sensors all which drain power.
If you compared an iPhone 5 to an iPhone SE you can really see how much effect newer more efficient processors and better code have as the screen size is the same.
