Will the iphone take longer to drain when paired with an apple watch?

Question

iPhone

In most cases, I take out my phone to read notifications. I turn on the screen, look, hide and turn off. Most often, this is mail that is unnecessary to respond to. If you have an apple watch and view notifications through them, will the battery last longer? But what about the fact that the phone is constantly synchronized with the clock? In general, who yuzaet, share your experience.

Answer 1

Bluetooth eats little. And the fact that once again you don’t have to get it is a fact.
Previously, charging the phone was enough for 1 day. After buying the watch, for 2 days.
