I'm Seamus Byrne, from CNET, with another quick tip on saving mobile data.
If you love using Spotify, all those hours of music streaming can start to push you up towards your data cap, but changing a few settings can help.
Go to Settings, and then Streaming Quality And then choose Normal, so that you have the lowest available option.
Don't forget you can also download playlists if you're a premium member, so that you're not always streaming data when you're out on the road.
The same basic rules will apply for any music streaming service.
Just check your streaming quality settings, and adjust to something that you're happy with.
