How would I improve battery life(and if possible, boot time) on a laptop with openSUSE leap 15.5?
I have it installed on HDD, on a Lenovo Ideapad 3 gaming laptop, with a nvidia GTX 1650 Ti. I have windows installed, but it's on SSD, so it probably doesn't affect.
The battery life is not so good.
I have the proprietary nvidia drivers installed. In nvidia settings, I've set it to be in adaptive mode to save energy.
I've installed suse-prime and set it to offload. Setting it to intel doesn't get me to the graphical interface. Is there a way to fix that?
I use kde plasma and the effects and animations are turned off. I have disabled the cups.service, file indexing and other things I normally don't use.
Autocpufreq is installed and tlp is not.
I've also set noatime for root and home.
My screen brightness and sleep settings are kept low and I normally don't use more than 20% and at night only less than 5%.
I only get around an hour to 1.5 hrs of battery time on average. Are there ways to improve that?
Also my current boot time is around a minute to 1.5 minutes. Is it ok for hdd? Or are there things that I could easily try to speed it a bit more?
The most obvious solution to boot time is change the HDD to an SSD. Boot time of 90 seconds seems in the ballpark for a HDD. Disk drives are slow. An SSD should also improve battery life slightly. Though, such a short battery life, like that which you described, would point to a failing battery unit. Though, that's just speculation.
