I have an iPhone 7 running 10.2.1, and I'm mostly happy with it. However, there is 2 odd thing I've noticed. When I check on my battery usage in settings, at the bottom it says, "iPhone has been plugged in since the last full charge." However, that simply isn't true. I've purposefully not plugged it in to see how long it'll go during normal usage, so I know for a fact it hasn't been plugged in. I've also noticed this before. Has anyone else seen this? I know it isn't a big deal, and I don't plan on doing anything about it. Simply strikes me as odd.
