I have an iPhone, Watch and some Bluetooth headphones. My headphones aren't always connected and neither is my watch. So I'm thinking, why not leave my phone's Bluetooth on constantly so I'll have a seemless connection between devices? But then I thought, how would that impact my battery?
So, does having Bluetooth on constantly on my iPhone affect battery life? If so, how much?

don't think it is much of an impact. i leave mine on so it will connect to my headset, car or speakers when i turn them on. i doubt it is much of a draw at all sitting at idle. never seemed like it to me anyway leaving it on.
It won't affect the battery much... Maybe at most 10% in 3-4 hours and that is almost negligible. It also depends on how frequently you use your phone lol. I always keep my Bluetooth and Wi-Fi on and I never have my phone dead at the end of the day!
