Manjaro: Slow, runs hot and low battery life on my laptop

Hey guys, having some issues with Manjaro using a fresh install of the latest release on an Acer Aspire 5.

Just through normal use I notice the laptop continually runs quite warm and the battery life is extremely low compared to windows, about 2 hours in Manjaro vs about 8 hours in Windows 10. I also noticed that overall the system is just slow in general, one frustrating example being that typing is really laggy. Even now it sometimes takes close to a second for the screen to catch up to what I’m typing, it’s very jarring.

I have a suspicion it has something the issue might lie with my video driver, however I don’t have any options to change the actual driver in the manjaro hardware settings, it seems to just be happy with whatever came with the OS.

Wondering if anyone else has had any issues with a hardware setup similar to mine and has any tips?

Pasted my inxi below, let me know what else you need

Ok. A longshot but… does anything change if you use session instead of wayland?

I’ve had similar issues in the past usually related with wayland but it has been quite a while. And if I read this correctly the speed of the CPU is quite high.

I actually just switched to Wayland yesterday in hopes that it would speed things up, but good thought!

Switching back to Xorg doesn’t seem to help sadly. Going to try out a few different kernels to see if anything helps

You’re using quite a bit of RAM(90%) maybe that’s the cause? What is consuming so much???

Firefox is using an absurd amount of ram! Definitely could be part of the problem.
