Pinned tabs are a handy feature - for messaging apps and email it ensures you get notifications as they come in. However, you pay for this convenience with battery life - Discord alone consumes a gigantic amount of battery when in the background. All so users don't miss a ping. This seems wasteful to me. Most notifications don't need to be replied to instantly, and you could afford to wait a few minutes to get them.
It would be helpful to have pins that prevented the tab using resources for the most part, but then woke and pulled data for brief periods to get updates every X minutes - perhaps set by the user. 5/10 minutes seems a sensible default, with the user being able to set updates in multiples of this themselves, or just whatever interval they like.
I would mostly be interested in this as an extension of the "Low Power" mode Orion offers, but would be open to seeing it be added as an extra feature alongside it.
The user would enter this mode by right clicking select pinned tabs and entering them in to mode.
This mode would sleep / reduce the update frequency of the tab to a user-defined interval, in the hopes of reducing battery consumption via reduced CPU usage etc.
The tab would update every X minutes. Notifications would therefore come in with some delay, but perhaps the potential battery life trade-off is worth it.
