Why is my 128GB iPhone 6S so low on storage?

My two most space-consuming apps or my music and photos, which combined take up exactly 11GB. All my other apps combined use up about 10GB total… So why does my phone say I only have 8GB of space available? About a month ago I checked and it said I had 80GB of available space.

Is there a good Iphone emulator out there for Windows?

I'm looking to play a few free games on my Iphone but I keep having the games crash on me left and right after only a minute or two, it's probably because my phone is old as balls and is just breaking down but I don't have the cash to get a new one right now, so I figured I'd see if there was an emulator out there that could let me play the games all the same, maybe even a few of the Japanese games like Digimon Linkz >w>

So any advice here guys?

How to transfer iPhone photos to PC?

I have an iPhone 6 and I want to transfer the photos I've taken on my iPhone to me PC so I can delete them and make more storage room on my iPhone.
I've had an iPhone before and I used to just use the File Explorer with my iPhone 5, but for some reason when I plug my iPhone 6 into my computer it doesn't come up on File Explorer?
IIm running with Windows 10.
I tried also using the Photos program on Windows 10 and when I go to Import, it says I need to connect a device.

's weird because when I plug it in, iTunes recognizes my phone just fine and my phone is charging, but it doesn't come up in other places on my computer. I've also authorized the phone to trust the computer. So I don't really know what to do now.
I also tried uploading them onto Google Drive and it's been stuck on the same photo uploading for over a week now. So any help on what I can do now is appreciate.
