> if OS updates slow down older phones these days On the Android side, it's sorta debatable whether Google Services is really part of the OS or not, but in any case, a Galaxy S4/5 with the latest google SW is a performance disaster. Maps regularly freezes for like 3-5 seconds at a time; its sluggishness is almost certainly causing additional auto accidents. Pretty much every other G app takes more than a second to open, despite being compiled-to-native-code during installation. Disabling airplane mode will cause 100% CPU on all cores for like 15+ seconds. Performance was certainly better when the phone was new 4-5 years ago.
