How to Keep ChatGPT Running in Background Chrome Tabs

If you switch tabs while ChatGPT (or Claude/DeepSeek) is generating code, you often return to a red "Network Error". This happens because Chrome aggressively throttles JavaScript timers in background tabs to save battery. When the tab is throttled, the WebSocket "heartbeat" fails, the server assumes you disconnected, and the generation terminates mid-sentence.

The Manual Fix

Drag to New Window: Pull the ChatGPT tab out into its own dedicated window and keep it visible on a second monitor.

Play Silent Audio: Run a 10-hour silence video in the background of the tab to trick Chrome into thinking it's media (messy workaround).

Disable Throttling Flag: Go to chrome://flags and search for "Throttle expensive background timers" (Note: Google frequently removes/renames this flag).

The Automated Fix

SuperchargeBrowser offers a Smart Whitelist solution. The strategy is not to disable efficiency, but to direct it. You add chatgpt.com to the Supercharge Whitelist. Our engine then aggressively suspends everything else to free up resources, while explicitly acquiring a "Keep-Alive" lock for your AI tab to ensure the WebSocket connection remains pristine.

Technical Root Cause Analysis

Real-time AI streaming relies on WebSockets or Server-Sent Events (SSE).

The Throttling: To save battery, Chrome aligns background JavaScript timers to wake up only once per minute.

The Failure: If the AI server expects a "heartbeat" or acknowledgment every 5 seconds, and Chrome delays it by 60 seconds, the connection times out.

The Whitelist Strategy

Most users try to disable throttling globally, which ruins battery life. The correct engineering approach is Selective Persistence.

Granular Control: SuperchargeBrowser allows you to say "Maximize battery on these 49 tabs, but give this 1 AI tab 100% CPU priority."

Result: You get the generated code without the "Network Error" and without the dead laptop battery.
