There are more efficient formats like JPEG-XL, HEIF and WebP. If you convert the RAW -> JPEG -> WebP you are losing more quality. I think iPhone uses HEIF format.

Likely because almost every electronic device and software under the sun is JPEG compatible.
But they could give you an option to change it. For example, in my OnePlus I can choose video in h264 or h265 format. Photo there is no option, just JPEG.
The overlap between “cares enough about image quality to not be okay with jpeg” and “doesn’t know to install a third party app” is probably too small for most manufacturers to care about.
My Samsung has the option to save as HEIF. When I want to share that photo, my phone shares the HEIF file which isn’t commonly supported.
An iPhone also saves as HEIF - however, it automatically converts to jpeg when you share. Much smarter, more seamless.
In some scenarios the iPhone will ask you (which is good) whether you want to share the photo as is or convert it to jpeg like yesterday when I tried to send a photo on telegram as a file to avoid the unwanted recompression
Because that’s the way it was designed. And yes., it can be a pain sometimes sending photos and videos, but I will never consider buying an iphone.
Mine has like sixteen different options, including several lossless options.
Curious, what device and what app(s) do you use?
The default camera app on the Blackview 9900.
Very interesting
