Cell phones record images in raw format
(Unless I'm mistaken) and converts it to JPEG photo.
What happens to that raw data? Does it go to trash or immediately erased? Just curious

If the phone does not save it, it most likely is dumped after the conversion to JPEG as it is no longer needed.
It does NOT go into the "trash can".

I was wondering ir it went to trash and still up memory. Thanks

I seriously doubt it.
If I wrote the program it wouldn't hang around. Waste of space.

Same question if you set your camera for JPEG only does it save the raw somewhere?

I doubt that also.
Easy to check in the file system though.
It WON'T be saving it in camera memory!

No I think neither of them save the raw data. Let think of it this way. When you shoot JPEG the camera has to capture the raw in the fast buffer then convert it to JPEG to write the card. When you shoot RAW the camera just write the raw data to card. Yet most cameras do it faster to convert to JPEG then save to card than simply write the raw data to card. So writing the data takes the most time and it can't do that if it saves the raw data.

"Fast buffer", as in camera memory?
Is there a slow buffer?

Is it possible that data is retained out of sight in the cache?

When a device slows down, bogs down, whatever, and it's possible to clear the cache to gain back better functionality, is it possible some of that cached data may be from out of sight raw files? Or, not related?

the buffer is fast. There is no slow buffer.

Possible, but highly improbable!
"Cache" is part of the camera memory.
The cache would have to be large enough to store how many "RAW" images then?
If the information is no longer used after the creation of the JPEG, why keep it?
Total waste of memory space to save in cache memory.
Then what happens when the camera is turned off? POUF?

Is that probably the same in cell phones?
Are their memory and processing circuits very close to the dedicated camera design, or more complex?

Sufficees to simply say buffer then.

Fast buffer vs slow memory card.

And your point is what, regarding the discussion of what happens to RAW data when RAW is not saved?
I seem to be missing it.
