This gives better performance and also perf/watt compared to current value of 115. For example: Speedometer 2.1 score: +19% Perf/watt: +5.25% Webxprt 4 score score: +12% Perf/watt: +6.12% 3DMark Wildlife extreme unlimited score score: +3.2% Perf/watt: +11.5% Geekbench6 MT score: +2.14% Perf/watt: +0.32% Also update balance_power EPP default to 179. With this change: Video Playback power is reduced by 52% Team video conference power is reduced by 35% With Power profile daemon now sets balance_power EPP on DC instead of balance_performance, updating balance_power EPP will help to extend battery life.
