iPhone 6s: bluetooth and handoff significant battery drain

[Hyloba]

So I never had to use bluetooth or handoff before, but by getting a MBP, I started to use those options. My battery drained twice as fast ever since. I thought I had a faulty 6s battery, but today I switched off bluetooth and my battery is once again as good as before.

Is it normal for bluetooth to have such a big impact on battery life? I always thought it was quite battery efficient.

Bought a soundbar a few months ago and I started using a BT speaker with my iphone/iPad as well and would welcome more info.

I know having BT on will draw more power but how much more? Has there been any studies or tests?

Google search doesnt yield anything meaningful...

What does the battery stats in settings show?

Same as always, Safari on top with about 60% or more usage, followed by Messenger with about 10% and then some other stuff. It's the same with or without bluetooth and handoff on, only that it drains double as fast.
