Hello, Yoda_Soda.
Thank you for using Apple Support Communities.
I understand you're concerned about the storage space on your iPhone with apps taking up a majority part. I'd like to help. You may want to sync your iPhone with iTunes to see if syncing helps. Also, if you haven't done so already, restart your iPhone. Sometimes a restart helps resolve issues.
Check out this article for more information about storage: How to check the storage on your iPhone, iPad, and iPod touch
You also have the update downloaded, you may want to finish updating to see if your storage adjusts.
Keep me updated.
Cheers!
