Q: iPhone 5 storage?

Hi lheap14,

If you are having storage management issues with your iPhone, you may find the information and steps outlined in the following articles helpful (the first is aimed at iOS update installs, but is also useful for more general storage management issues):

In particular, if you are seeing unusual Photos storage, you may want to make sure that the Deleted Photos album has been cleared, especially if you have enabled iCloud Photo Library, as noted here:

Deleting a photo or video from your Photos app will also remove the item from iCloud Photo Library and from your iCloud storage allocation. Photos and videos you remove can be recovered from the Recently Deleted album for 30 days. After 30 days, your content will be removed from the Recently Deleted album.
