Yes, on the iPhone is even more subtle because you can’t have access to the folders inside the filesystem. Anyway I’m using less than 50GB on my iPhone, is hard to keep the space low because you have to check lots of things. For example I had almost 1GB of Health data that were steps and other things from years ago but I wasn’t able to free this space also after that I deleted all the records inside the Health app. Finally I discovered that these data were from Apple Watch cached data, I had to disable the health app on the Apple Watch and then I went able to retrieve back my GB (3/4) of cache. In this situation the records were useful (if you need it) but it was very difficult to find how to clear this space if you don’t want all these data. I’ve never thought that were data from Apple Watch stored inside the “other space” on the iPhone. At least not some GB.
