Apple appear to have done nothing new (ahead of the game or truly innovative) since the passing of Steve Jobs. Apart from some box engineering (including a butt ugly box watch), create a mountain of connectors and increase the price of everything to just above stupid level. Have they produced anything significant since the great man's passing? and if not - how do they justify their income? - oh yes - just keep putting the prices up.
Lol.
I assume you're only here for an echo chamber, but you made the mistake of including question marks, so I'm gonna bite...
I'd say one HUGE innovation in the post-Steve era was the creation of TouchID, w/ the incredibly novel approach of creating a secure enclave inside the CPU, not storing the fingerprint itself, etc. It was a HIGHLY technical solution w/ unheard of security, presented in a manner that had all the elegant simplicity that was Steve's hallmark.
I believe it was that same year that they surprised all the "leakers" by announcing the wolrd's first 64 bit smart phone processor. In a world where it seems like Android phones ALWAYS get hardware features first, it was quite the coup. Samsung was tripping over themselves to respond! I remember the CEO making these two awkward and contradictory statements in the same breathe: "that's COMPLETELY unnecessary & there's zero benefit to a 64 bit chip..... besides, our next flagship will have it too!".
I'd say, when the Apple Watch showed the kinda silly feature of sharing your exact heartbeat, it hearkened back to Job's habit of cooing over how Apple really put the "personal" in personal computing devices...
Terraced batteries are an innovation, for sure! I can scarcely believe no one had done it before (lol, a true indicator of the simple, yet brilliant). I think that solving the literal decade old issue of BlueTooth pairing annoyances and issues in one fell swoop w/ the design & creation of the W1 chip is a sterling example of innovation. Indeed, being the one company behind an increasing number of self-designed chips (now including the A10 Fusion, which itself houses the updated G9 graphics chip & the M10 motion coprocessor, also Apple Watch's S2 system on a chip, the T1 powering the TouchBar & providing security and encryption for TouchID & web camera, and the aforementioned W1 chip) is quite innovative as well.
I'm not discounting missteps or being an apologist for dongle annoyance, just keeping it real.... saying that Apple quit innovating after Steve passed is putting the blinders on.
