I sure do. I guess it’s part of being mildly obsessive compulsive. Whenever my iPhone battery dips below about 60%, I start getting worried. That’s why I have a car charger and carry around an external charger. Never mind that since I got my iPhone 5C last summer, my battery has never completely run down. My wife and son have no problem draining their batteries down to single digits, but I just can’t do it. I guess I’m funny that way. At least there’s a term for it.
No quick fix for battery anxiety but plenty of workarounds
