Watch Saving iPhone Battery

[TallManNY]

Assuming that the Apple Watch in use results in folks not turning on the screen of their iPhone as much, will it result in longer battery life for a users iPhone? Could we end up in a situation where the watch needs recharging every day, but the iPhone 6 (or 6+) becomes an every other day charge?

Or will the contacting and interaction through bluetooth cut into the savings in not illuminating the iPhone screen?

I would think the power savings from having the phone's screen off many more times due to watch usage would greatly outweigh the minimal drain from Bluetooth usage.

I have Bluetooth on 24/7 anyway so I'm expecting to see a big jump in phone battery life.
