Feeling the crunch
My iPhone 5 shows 230MB free out of 5GB. What is the best way to free up space? Clare Russell Social networking apps aren’t generally very large, but they can cache quite a lot of data, which builds up over time. So, deleting and reinstalling Twitter and Facebook might free up a few hundred megabytes.
You’ll likely save more by moving photos off the phone. Even if you don’t want to use iCloud Photo Library, importing images to Photos on your Mac and deleting the originals from your iPhone will likely free up a few gigabytes. To confirm what’s using space, go to Settings > General > Storage & iCloud Usage (or Usage, prior to iOS 9).
