Hi all, I have an iPhone 6 updated to iOS11. I noticed it's been quite slow in the last few days, sluggish, apps taking 5-10 seconds to load, keyboard appearing after 2-3 seconds.. Then I noticed in the iPhone storage section that I have "55GB of 64GB used" - that should leave me with plenty of space. From the iTunes iPhone page, I'm told I have around 7GB of free space. But using a "Usage Widget" app it tells me I only have 1 or 2Gb free. What do you think?
