iOS power consumption analysis required

It would seem that a CPU might be spinning waiting for soft key input or MIDI events. I’d love to solve this, but i’m an iOS development amateur.

I would need more information to determine if 42% was an unreasonable amount or not.

When I was writing the dsp: whenever I had a choice between higher quality and lower battery I always chose higher quality.

i would agree 100% with you since it's an audio app - except the battery won't charge on a 87W power supply with the app not being actively played/no current focus...there has to be a balance...like if the app is not in the foreground, it goes to power saving mode. As i indicated, the MPC Pro 2 is in the background and not even showing up. I'm coming from a java/scala/python/c background and am just starting to learn (and hate) swift through the udemy course, so i'm not yet qualified to understand the event model and how to implement a hibernate mode. But i will look into this as my skills improve.

You have some power-conservation options in settings:
