IPhone 6s constantly losing storage even when I'm doing nothing?

So I have a 16 gigabyte iPhone 6s, and ever since IOS 10, IIm constantly losing storage, even when IIm just doing nothing. I have been deleting and deleting apps and photos to get more storage, but the storage comes back for a little and then disappears. (Ex: I had Reddit on my phone, it took up 400 megabytes, I delete it, and I get 400 megabytes back, only to see in a few minutes I have 0 kilobytes of storage left.) this is so frustrating, I barely have any apps or photos, but it still says IIm using all my storage! All together all my apps and photos take up 2 gigabytes, and my update to iOS 10.2 only takes up 500 megabytes. How do I fix this? I can't take any photos or videos anymore, no matter how much I delete.

Download speed varies by device?

Added (1). I've been downloading games from Steam on my new desktop. The download speed usually stays around 1.1mb/s. I tried downloading the same game on my laptop in the same location within the same time frame and the download speed stayed around 1.8mb/s. My sister gets 5mb/s on her laptop all the time. What changes this by device and how can I make my download speed faster on my desktop?
