High energy use

[Lownin]

Energy use for Caffeine is higher than I'd expect, with Activity Monitor reporting an energy impact of 2 or more with Caffeine at idle, when other background app are typically under less than 0.5, even Electron apps like Discord.

I think this might be a non-trivial use of energy considering what caffein does.

Thanks!

No.

FYI their repository is at https://github.com/IntelliScape/caffeine/ . It looks like they disabled "Issues" entirely?

I believe that's a mistake. Issues are disabled by default in forked repositories.

I also have this issue, which led me to remove the application.

I was hovering around 8.5 energy use when some like Chrome (a notable resource hog) with 10 tabs open was only at 1.4. This energy cos rivaled multiple instance of Jetbrains Rider IDE, which is absolutely insane for something touted as "lightweight".

Great idea, but this application is unusable in its current state. I peeked at the source to make sense of it but it looks pretty foreign for my .NET/Javascript background. Hoping someone in the open source community can make sense of this and fix the issues.

I'm trying out this app, which merely wraps the caffeinate command that Apple added: https://github.com/newmarcel/KeepingYouAwake
This is likely to work reliably without issues, as starting/stopping an Apple-provided command should not cause power usage.

At the time of original development of Caffeine, the caffeinate command did not exist, so that was not an option. People using older/vintage Macs which cannot run newer macOS versions will still need Caffeine for this functionality.
