I recently worked on optimizing battery life on Linux laptop using TLP. While default Linux gives users some control, battery efficiency often requires extra tweaking.

I tested various settings on my ThinkPad T14s Gen3 (AMD) and managed to increase battery life from ~ 8 hours to ~ 10 hours using TLP, CPU scaling tweaks, GPU power management, and battery charge thresholds.

Some key takeaways from my findings:

-- TLP config tuning significantly improves power efficiency.

-- CPU scaling and boost management can extend runtime while keeping performance reasonable.

-- Setting smart charge thresholds helps prolong battery lifespan.

-- Lightweight desktop environments (like i3) & background process control make a difference.

This applies broadly to other Linux laptops as well.
