Is there anything I can do about this extremely vague block of data that’s taking up 30% of my phone’s storage? Mind you, this isn’t the operating system itself, as that’s listed as its own category.
EDIT: I tried (a) backing up to my computer, factory resetting, then restoring from backup and (b) setting the date years in the future. Neither worked, in fact (a) actually increased my system data to 34 GB! What DID end up working was updating my iOS from 18 to 26, which I had to do from my computer via iTunes since my phone was full. Apparently major system updates reset system data
raster image caches are way way faster to display than the raw vector images
Yes, those would be cached in RAM.
that's an entirely different thing. both raster and vector images are cached in RAM in probably the same format. that doesn't make vector images faster
Oh, sorry, I didn't realize you had literally zero idea what you were talking about about.
loading images from disk? i don't think they'd be keeping every single asset cached in their 6GB RAM all the time. unless you know of superior space-saving measures they have?
apple limits its set of screen resolutions to support as they are the sole provider of hardware supported by iOS. raster assets for each resolution would make perfect sense since they only have to support three or four different screen sizes.
