How to get more space on my iPhone?

My iPhone 5 is 16GB and I've used about 7GB and i have 6.5GB available I only have 17 apps and 317 pictures, but on my iPod I have 60 apps and 500 pictures and I've only used 8GB, why does my iPod have more space if it has more things? How can I get more space on my iPhone!

The apps on the iPhone are larger, hence the more space taken up by them. To get more space on an iPhone, one must delete items.

  • Will buying more iCloud space let me download more apps, songs, and photos? So i have deleted apps that i don't really need and deleted songs i don't listen to but still there's not enough space to even take a photo, A pop up comes up that says to manage my icloud storage. Would purchasing more icloud storage allow me to download more apps and have more songs and pictures on my iPhone 4 from sprint? It is an 8gb i think.
  • Why does my Iphone music take up more space than it should? I have 1831 songs on my Iphone, very little photos or apps. Yet the songs themselves are taking up 11GB of space on my Iphone. Which seems way more than it should be to me. I was wondering why it is taking up so much room and is there any way I can fix this?
  • What is the best way to backup iphone to get more space? I can't update this iphone so I need to remove 3.6GB of photos and 3.2GB of music. I don't use icloud… Should i? Maybe place the phone into the computer and use itunes to backup and remove?
  • More you use an app the more space it takes up on iPhones and iPads? I have an iPad and new iPhone 5 that I just got. I have rhapsody on both the same app and amount of music basically (iPad as seven more songs on app) but on the iPad the rhapsody app takes up 2.8 GB and the iPhone takes up 1.8GB. Why is that? The more use the app the more space it takes up even if you're not adding new content?
