I’ve installed TLP on my Lenovo ThinkBook laptop and was wondering if there are additional steps I can take to extend the battery life when using the laptop unplugged.
Could you please share more tips and tricks for maximizing battery life on Linux laptops?
For more power savings, you can undervolt your CPU if it supports it. On some CPUs, it can result in significant power savings.
Undervolting requires a lot of testing to make sure each core is stable under all conditions. There is no guarantee that a CPU will undervolt well though. Two identical CPUs can have significantly different results.
undervolting can also improve performance, depending on boost behaviour. it feels like you got a better binned chip.
I don’t see how undervolting would result in power savings on modern CPUs if you’re not up against clock limits as the CPU would simply boost higher.
