#Help an arch user with his first laptop ever

Dude, I really don't understand anything about notebook energy, and also something that I think is worth mentioning is that since I bought a cheap notebook, its battery didn't come in very healthy, browsing the internet and editing some videos (not rendering, just editing in kdenlive) and using the brightness at 60% the battery lasted 3:30h without breaks, I use it most of the time on its charger (I don't leave the house with it), so I would really like to know about these absurd gains, because what was my thought, I'm using a somewhat "heavy" system and doing this kind of thing the battery lasted three hours, people say that from a window manager to a desktop environment the energy consumption is much lower, thus causing a lower and longer lasting battery use, so if I use dwm + tlp, which people say is a "complex" tlp configuration that doubles the battery life, it would be really cool to spend weeks configuring this correctly, which is what I would really like to know is if these premises are right or not, you know?
well tlp would let you completely gimp your cpu to very low frequency, and I'm sure you can get more battery life if you optimize it, but it will always be a tradeoff with performance. when I tried tlp out i didn't change too much of the settings, just a few of them like cpu governor etc, to be honest i didnt really notice much difference. if you limit the cpu clock speed etc, you can probably get some more battery. like I said just using the power profiles daemon setting and powertop autotune was ok for me
the problem was that tlp and power-profiles-daemon are conflicting packages so you can't have both, and I really needed the power profile swapping function of ppd to switch the profile for when I play games and want performance. I'm sure you can make some workaround for that using tlp though,i just didn't want to do that work
My laptop usage is just to surf the internet and code some stuff, I just edited that video in a late night daydream, but it's not something I usually do, so I think downclocking it wouldn't be negative for me, the only thing I'd like to know is "how much" extra time I would gain by doing this setup
you can use tuned service
sorry, but what are you talking about?
If it is an Oracle solution for powersaving that I saw on Google, it is very interesting, but my main question is whether it is worth using any of these battery configurators in my case. My main question is how much time it would increase when using it off the charger.
look for it. it's on the aur. I use it on plasma and auto manages my power
it's automatic
you can get like 20%ish more
- with an aggressive power saving profile
like 35-45 minutes ?
tuned is the goat
tlp good, but may be overcomplicated
tuned runs as a service, can be used with gamemode too
.aw gamemode
i use ppd cuz it also caps the cpu/gpu temps to like 80 so my laptop doesn't take off into orbit everytime i open a game
i just navigate on internet and code some stuff
can't say for sure till you try it yourself though
it depends on how good the default power management from the manufacturer is
if it's really bad maybe you can get a bit more than that, if it's already decently optimised probably less
my last laptop was a lenovo and it was horrible, but it was an ideapad not a thinkpad
I'll be focusing on this in the next few weeks, but a lot of people say that ThinkPads are different when it comes to these power settings, have you heard about this?
nope
still, tuned helps
... tuned
