Ways to make a laptop’s battery last longer

Try and decrease the amount of background and start-up processes. Also, is it a gaming laptop?

You should I think on Windows see power usage / intensity in task manager. I would be having a look there to see if there's anything running.

But the reality is there's only so much you can do and so much you can squeeze it especially for laptops that weren't designed to have super long battery life.

Depending on the laptop I'd also suggest looking at external battery banks that can power it. I have one that I can plug my macbook into and while it won't actively charge the battery when there's anything more than an idle load, it does give me an extra hour or two when I need it the most.

just have it charging while youre using it

I just unplug the battery if I'll use my notebook for a long time without moving it

Screen brightness is a pretty big factor, try turning it down to a point where you can still see but it's not at max level.

Disabling auto start or background execution of apps you don't use enough to justify them draining battery also helps.

↩ @'FT ' actually i think it only harms the laptop if the battery is already full while youre charging it

↩  ThePyroManActualAccount yeah but thats what people usually do

↩  RedEastWood Good luck getting everything working properly… but, hey, it’s better than BSD, right?

↩  ThePyroManActualAccount apple keeps your battery at 80% when you plug it in and are actively using it. if slowly charges it to 100% overnight and this is a feature on their laptops and phones. On Mac there is also a program called AlDente which never lets your battery go past 80%.

If the battery is replaceable then don't even bother trying to adapt to some ideal battery usage. You shouldn't have to do this anyway as at least with apple it adapts to you.

Make sure drivers are up to date, decrease screen brightness, and use the balanced power plan rather than high performance. Obviously gaming laptops aren't known for their stellar battery life so that's just a given

can confirm (at least with an iPhone X running iOS 15.1), it charges up to around 80% and slows charging by a lot, which i guess will help battery life

What version of the MacBook / MacOS did they introduce that out of curiosity? I've never noticed it actually doing it but I'm not quite on the latest MacOS yet...

↩ @'Ryan' I'm not sure. It's been there since Big Sur on my M1 Mac. I think it may have been introduced in Catalina or a later version of Monterey for all Macs

↩  Telesphoreo Interesting, it's not on my Intel Macbook Pro in Big Sur, I need to wipe it and put Monterey so will have to see if it was added there.

↩  RedEastWood Thought you said Pop!_OS?
Honestly unless you use Gentoo (which is a pain in the ass), I’m not impressed, but you did a (somewhat) good job… hopefully it’ll help your battery.

↩ @'r00t' better than manjaro as well
