This anecdote is hard to believe (the slows the phone down part) because unless the app is constantly hammering the storage system with I/Os even as a background process, storage usage doesn't mean it's actively slowing the Phone down. Also it turns out that caching people's photos, etc., will save a lot of bandwidth and improve loading times (especially precious on mobile). Those JPEGs add up quickly...

Honestly I don't know how much consideration devs are actually paying attention to when most of them are probably using fairly recent high-end phones instead of the super cheap low-end mediatek android phones.

I've also noticed that low-end android phones tend cheap out on storage since most people only care about the size of storage not the speed.
