But it’s weird and lazy that on an 8GB phone they kill the app rather than just suspend it (to stop it using any cpu)?
On iOS, even in low-power mode, and on a phone with far less RAM, apps rarely have to reload unless you’ve force-quit them or have gone for days without using them.
Hence my personal belief: GUI operating systems must evolve to slow down to match user-expected frequency of stimuli. Too fast and users leave, so they add crufts and weights until it's slow enough.
Android and iPhones thought they'd look cooler if they didn't, resulting in a decade of endless frustration for many users.
I'm pretty sure that the task bar and start button could get swapped out btw, but they're quick to reload (except for the start menu and the tray icons)
This drives me absolutely nuts.
