I have visuals of what you have said. If not for the sudden drop due to tariff war/ CFO issue/telcos subsidy, revenue of AirPod/ Apple Watch/ Services is sufficient to compensate for the plateau-ing iPhone. Articles claiming Apple is not doing anything about the plateau-ing have intentionally ignored the AirPod/ Apple Watch/ Services, and the current R&D in AR/Healthcare products & services or they are deaf and blind.
