Unified Remote draining my Pixel battery, could it be?

I finally started connecting my TV to my desktop PC and I've been recommended this app to use the mouse remotely from my bed, rathen than getting up and going to click on the mouse all the time.

My room is small so I can't really fit in an extra table with a wireless mouse.

Unified remote is great and I'd recommend it to anyone, except my phone battery is unusually draining way too fast.

For instance I've used my phone just a little today and tonight is at 15%, it never happened before. I haven't even used Unified Remote but I'm wondering if the server is running in background all the time (or if it's connected all the time).

Sorry, I'm not a big expert, so I'd like to ask you guys, what's your experience with Unifed remote?
