vscode: Bug: Battery drain even when app off due to Shan.code-settings-sync extension
Issue Type: Performance Issue
on brand new Apple 2022 Macbook Pro 14" M1
- download vscode (universal mac version)
- watch battery drain
I had >90% power 2hr ago and now I’m down to 46%, and I was using chrome but my mac tells me that vscode was using more power than anything else EVEN THOUGH I HAD YET TO TURN IT ON TODAY
Please look at this insane amount of battery usage for an app that’s turned off:
Update: It looks like there was a Code Helper (Renderer) (50803) task running from vscode that was using half of my CPU. I stopped that process. I opened vscode up again and it seems to be using a reasonable amount of CPU now (both that task and the Electron/other vscode-related tasks in total, that is). so maybe a background task just doesn’t quit and slowly snowballs over time.
Update: Looks like everything is going fine now! So it must be due to some task that gets started right after install or first startup. Below, you can see my usage with vscode off and before I turned that task off, then I charged my comp, then I reopened vscode to do things and it’s consuming expected amount of power.

I had this issue for days until I uninstalled the settings sync extension.
I really hope there is one soon… My 16 inch MBP 2021 went from full to 10% in under two hours. It hit 198 in the energy tab of activity monitor, and it hit 432% cpu usage… Crazy bug!
Thanks for opening this issue. We have reached out to Shan the author of the Settings Sync extension and he told us he would fix the issue in the next month.
My personal recommendation is to use the VS Code built-in Settings Sync functionality instead. More details here: https://code.visualstudio.com/docs/editor/settings-sync
Kill the process
Code Helper (Renderer)in activity monitor. After that it works fine for me.Related ticket: https://github.com/microsoft/vscode/issues/101555
The extension author of the Settings Sync extension agreed that we mark it as deprecated until they fix the performance issue. There is no follow up work on our side, thus I am closing this issue as done. Everyone that is using the settings sync extension can use the built-in settings sync functionality instead https://code.visualstudio.com/docs/editor/settings-sync
Given the comments in this issue and the extra information we received, I chose to change this issue into a tracking item for the 100% CPU used by the
Shan.code-settings-syncextension.@miyurusankalpa If you are not using the
Shan.code-settings-syncextension and experiencing high CPU usage from one of VS Code’s processes, please take a look at https://github.com/microsoft/vscode/wiki/Performance-Issues#consuming-cpu and create a new issue pointing out the process which causes high CPU usage, your platform (universal or arm), etc and we can try to troubleshoot together what’s going on. You can also link here to the new issue. Many thanks!I don’t have this extension installed, but still got the issue. However I’m developing my own extension, which uses a separate process as well, so I suspect the problem is caused there in my case. What I’m trying to say with this: Maybe just fixing the issue in the settings sync extension isn’t enough, as this might occur again in other extensions.
Thanks for this, the vscode decreased to normal usage level once i uninstalled Settings Sync. Hate to let it go but its not worth my mac running for 1 hour at full charge. My battery health is already at 95% for a 3 months old Macbook Pro M1 14"
Same problem here, it is very boring to kill every time the Code Helper (renderer) process. Is there any permanent solution?
