Questions
Does SystemBatteryAnalysis work on iPhone Duo?
Yes. SystemBatteryAnalysis is built for iPhone Duo — it runs full screen on the 7.6-inch inner display and adapts its layout for the fold.
Does SystemBatteryAnalysis work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
