Hello guys! I recently bought a new laptop and started

using TLP. I got a template configuration for an Acer laptop recommended on arch wiki whose model is very similar to mine (mine is a515-51g): http://ix.io/3DMv

What I noticed right after that was that, when running off the charger, on the battery, the CPU usage is often times near 100%, so the CPU usage gets higher when running on the battery which reduces the performance considerably to a level that it gets difficult to even watch videos on YouTube. I changed the setting CPU_MAX_PERF_ON_BAT from 25 to 100 and the problem seems to have gone away. Can someone explain me why was this happening? Wasn't it supposed to have lesser CPU usage when running on the battery? Thanks!

This doesn't make much sense for me. Does the setting disables cores or reduces clock? Because what happened was that the reported CPU usage actually got higher when on battery...
