Miscellaneous Information:

Is there a way to see a little deeper into Brave? I'd like to know what processes it's doing that take so much. Like a task manager for the browser itself. These things are OS's anyways.

There's a task manager in the more tools section off the menu. If you can update to 1.5.115, we believe we fixed th issue with this fix #8779

[kjozwiak]

@SephReed if you're still having issues with the 1.5.115 which is the latest build, you might be running into #8846.

If you run through the info that @rebron provided via #8901 (comment), let us know which service/tab is the one that's causing the spikes. If you notice it's Utility: BAT Ledger Service, it's related to #8846.

[SephReed]

It is the BAT ledger Service

Awesome! Thanks for confirming 😄 I'll close this as a duplicate of #8846
