It should do all that in the background when your phone is sleeping!

Case in point, the iPhone can make an AI synthesis of your voice. It’s meant for people who are in danger of losing their voice. (I recently had dental work done. Let me tell you, that feature came in clutch!) You read 150 lines it gives you, it takes about 15-20 minutes, and then it builds the voice profile over about 8-12 hours depending on phone model (requires an 11 or 12 or newer) while the phone is not in use, and on the charger. This is awesome because it’s doing the kind of work a phone should not be doing, as it would interfere with your operation of the phone, but it’s doing it at a time when you’re not using it (e.g. asleep). I did it on a 13 Pro and it took 2 nights. But now I have it, and the model transfers from phone to phone… Not trying to promote a feature (but if Google could steal one feature, this would be it because it’s super useful when you need it!) but rather, the process of doing CPU/GPU intensive background tasks… when the user is asleep.
