The honest numbers
This is a 31.5 MB dashboard tool, not a 3D game. Expect battery impact similar to a messaging app: noticeable only if you leave it open for hours. Data use beyond the initial download is small, mostly binding handshakes and dashboard refreshes.
Trimming usage
Close the app instead of leaving it in recents, and disable background data for it in Android settings if you are on a tight plan. Neither breaks anything; the app reconnects when opened. The low end guide covers the broader optimization picture.
When usage spikes
A sudden battery jump usually means a stuck session retrying in the background. Force stop the app once and the drain stops. If it recurs, reinstall from the official download page.
Emulator note
On PC none of this matters much, which is one more reason the emulator setup appeals to heavy dashboard users.
