Disable Chrome Efficiency Mode for Specific Tabs — The Whitelist Trick (2026)

Chrome's native "Energy Saver" is a blunt instrument. It throttles *all* background tabs. This breaks real-time dashboards, crypto tickers, and music players. Users are forced to choose: disable it completely (and kill battery) or suffer broken apps.

The Manual Fix

Global Toggle: You can turn it off in chrome://settings/performance (Not recommended).

The Hack: Playing silent audio in a tab forces Chrome to treat it as "Media" and exempt it from throttling.

Window Separation: Moving the tab to a separate window sometimes prevents throttling if the window is visible.

Global Toggle: You can turn it off in chrome://settings/performance (Not recommended).

The Automated Fix

SuperchargePerformance creates a Smart Exception. Our whitelist doesn't just stop suspension; it signals to the browser's scheduler that this specific domain is "Critical." We allow you to run Energy Saver globally for 99% of the web, while giving your 1% critical apps full power.

Technical Root Cause Analysis

Chrome uses a heuristic: Hidden = Unimportant.

The Problem: In 2026, many "Hidden" tabs are doing work (compiling code, tracking prices, playing audio).

The Solution: Granular Control. Instead of a global On/Off switch, SuperchargePerformance acts as a dimmer switch for each site.

FAQ

What is Chrome Efficiency Mode?

Chrome Efficiency Mode (also called Energy Saver) throttles background tabs to reduce CPU and power usage. It's Chrome's built-in power-saving feature, similar to but less configurable than a tab suspension extension.

Can I disable Efficiency Mode for specific tabs?

Chrome doesn't offer per-tab Efficiency Mode controls. You can only toggle it globally. For per-tab control over which tabs are suspended and which stay active, use SuperchargePerformance's whitelist feature — pin important tabs or add domains to the never-suspend list.

Is Chrome Efficiency Mode the same as Memory Saver?

No. Memory Saver discards inactive tabs to free RAM. Efficiency Mode throttles background tab CPU usage to save power. They work on different resources (RAM vs CPU) and can be enabled independently.
