1Password 7 affecting my laptop's battery life?

dodmcdund

Hey guys, I'm currently trying to understand what causes battery drain on my laptop and I think 1Password 7 is a potential culprit. When measuring my energy efficiency with "powercfg /energy", I find that 1Password is explicitly requesting a timer resolution of 1 ms instead of the default 15,6 ms of Windows (logs to follow) which is a pretty bad practice for battery life as discussed here:

https://randomascii.wordpress.com/2013/07/08/windows-timer-resolution-megawatts-wasted/

Question: does 1Password really need to do that? Wouldn't be a way to avoid asking this explicit short timer resolution so as to maximize battery life (at least when on battery)? After all, we all run 1Password in the background and I wish this isn't one of these apps greedily draining my battery...

Sorry for the french logs below, but feel free to run "powercfg /energy" to get a similar report:

Hi @dodmcdund,

Thanks for reporting this.

It is a confirmed bug with our lock view, we're asking WPF (Windows Presentation Foundation, what you saw as \WPF\wpfgfx—v0400.dll in the logs) to produce a subtle effect on the blue ring but it turns out that it is using something else in the background that spins up the CPU constantly when the lock view is left behind. If you close the 1Password window, the CPU usage is gone. It's not our intention to do this, it's something we found out after we rebuilt the lock view and noticed it. It'll be fixed in a future update soon.

For now, close the 1Password window when it is locked if you don't plan to use it for a while.
