For normal use, with multiple applications open and browser tabs in Safari etc I'm below 10% overall CPU use on my M1 Pro, drawing around 7-9W.

When opening mail.app and proton bridge I'm drawing 12-18W with frequent spikes into the 40s and overall user CPU usage is close to 20%.

Combined with the fact that my mail app regularly becomes unresponsive I generally just don't have my email client open when on battery, and rely on my phone or (ugh) webmail. If Bridge is going to be mandatory for using an external client (with FileVault & ProtonVPN on it seems a bit redundant) it'd be nice if it didn't double my power consumption and was more reliable.

macOS 13.2.1, Bridge 2.3.0
