- Add battery-drain-analysis.sh: Comprehensive tool to identify battery draining processes - Shows top CPU and memory consumers - Identifies network-intensive applications - Analyzes browser tab usage (counts renderers) - Provides actionable recommendations - Checks WiFi power management status - Update README.md with new features: - Document CPU power management capabilities (400MHz-4.2GHz dynamic scaling) - Add browser optimization tips (tab suspenders, task manager usage) - Add application management best practices - Document new scripts: cpu-power-control.sh, monitor-cpu-freq.sh, battery-drain-analysis.sh - Add BIOS configuration guide reference - Improve battery life tips: - Close heavy browser tabs (can use 77%+ CPU per tab) - Install tab suspender extensions (saves 50-70% browser CPU) - Manage chat applications (Element/Slack/Discord) - Pause file sync services when on battery - Screen brightness recommendations Identified issue: Single browser tab was using 77% CPU, reducing overall browser usage from 268% to 96% CPU
