Show HN: Boost Battery Life on Linux Laptops with TLP

Hey HN,

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.

Would love to hear your experiences! If similar? Anything I'm missing? What tweaks have helped you get the most out of your battery?
