As everyone is aware, the Spotify iPhone app doesn't allow users to clear its cache (please give kudos to this request!!!). Currently, the only way to accomplish this is to remove and reinstall the app. Doing this will clear out the cache; however, it will also wipe all offline playlists and users will be forced to resync.
If playlists have been synced for offline play in the desktop app, can they then be synced to an iPhone without redownloading them from Spotify's servers? In other words, does syncing an offline playlist that has already been downloaded to a PC to an iPhone take up any data? I'll test this myself as soon as I get the chance, unless someone can answer this for me.
I've moved to Australia from California and most broadband internet providers here have data caps (a harsh reality I've had to accept). I'd like to avoid chewing up my broadband data if I decide to clear Spotify's cache. If I can download all of my playlists to Spotify Desktop on my PC one time and sync them to my iPhone without redownloading them from Spotify's servers, that would be an OK solution. I've made an effort to locate a definitive answer to this question but haven't been able to find one.
Again, it would be ideal if Spotify would implement a Clear Cache button that clears the cache without removing offline playlists.
I previously only used Spotify for streaming and readily admit that I'm new to syncing, so if this is common knowledge I apologize for my ignorance. Any info about this subject will be appreciated.
