Cumulatively bitwarden background processes consume for about 1 hour of your battery for running full day! I just tested by myself couple of times. You can get almost 1 hour for free if you just quit bitwarden desktop app for a day!

Anyone knows what's causing that CPU spike every 10 seconds?

On windows too, it keeps using 0.2-0.3% CPU all the time on idle.

The constant CPU usage doesn't seem to be permanent. After the following sequence of events Bitwarden.exe is using effectively zero CPU (previously it was constant 1-2%)

I right-clicked bitwarden.exe in detail's tab of task manager after noticing it's high cpu time
I selected "analyze wait chain". Nothing popped up, but my bitwarden gui window closed
I tried to reopen gui from tray, windows pops up but is whited out, only menu shows.
I exit bitwarden by rightclicking tray icon and selecting exit
I restart bitwarden and unlock using windows hello

Here's some extra info that may help:

I am using browser integration, it was unlocked using windows hello from previous high-cpu bitwarden instance. It didn't need to be re-unlocked upon restarting bitwarden (that's not a problem)
I am on a work computer with local admin, but heavy (as in bloated garbage) Trend Micro endpoint security
PC is 11th gen intel 4c8t laptop and is not throttling, 64gb ram, bw installed on nvme
Bitwarden has only been open for like 15 minutes and has already read 293MB from disk and its slowly increasing.

I can confirm the same issue with Bitwarden Desktop 2024.8.1 (28903) on macOS 14.6.1. I only use the desktop app for unlocking the vaults in the Firefox browser addon (2024.8.1) now that it works again. Re-installing the desktop app didn’t make a difference.
