iPhone's battery life with AW

[R740]

Hey all,
I'm a long time iPhone 5 user, and just after I bought my AW (more than 6 months ago) I began to experience much worse battery life. When AW and iPhone are connected, it seems like my watch is draining battery from phone like crazy, and when I turn off my iPhone's bluetooth, battery life increases significantly. Is that because iPhone 5 has a much smaller battery, compared to bigger 6/6S/Plus or what?
Thank you!

Typically the Apple Watch doesn't drain much of the iPhone's battery if not running apps. I can go for many hours with the phone sitting at my desk and staying at 100%.

People who have had problems rebooted the watch/phone and that solved the problem.
