Mobile sanity tip: Don’t keep photos, audio or video on your phone. They’re resource hogs.
If you find your phone running so slow it makes you want to destroy things, destroy your media or move it to your computer. You’ll feel like a kid again.
Don’t target text-based data like call records and text messages. It’s not worth it. You’ll force yourself into making hard decisions about what to keep but see little gain in performance.
Go after the media.
