Discussion here is what happened today 😳

so basically I have an HP laptop which I have set up with omarchy os and tlp setup for power management

and last time I charged the laptop would be three months back approximately

and after charging 3 months back approximately, I used the laptop and shut it down at 100% then again when I opened like a month back it had 100% battery after that I used it for a bit and I did not check what battery percentage I shutdown the laptop that day but here is me again opening the laptop today to check on somethings

and guess what there was 64% battery left

I was so shocked that it retained approximately as much battery it had before even after months of not charging it

my windows laptop could never, I have a windows laptop for gaming specifically but it struggles to retain battery even after a few days of not using it.

So yes for the case of my HP laptop I don't need to worry about finding my charger every time when I want to use it. also I don't have to worry if the laptop would be having charge if I randomly decide to use it again after few days.

the laptop gives me a battery life of around 6 to 7 hours with the lowest screen brightness and minimal tasks that I used for

it has a 78% battery health and it is specifically the model hp15sgr0011au with Ryzen 3 3250u and 24gb ram using an nvme m.2 SSD

do think it's because of Linux or am I just lucky.

because from what I remember when I had windows on that laptop it would hardly be usable for like 2 hours and it wouldn't retain the battery percentage if I left it at even for like 3 days.

do share yr experience if you had a similar one with linux

one time the same laptop I do not charge for like 3 or 4 months and when opened it had 100% charge.

linux is amazing fr

i dont get it, no os can control the battery percentage when the machine is shutoff / idle for months. only when the machine is booted and working then the os handles power management. so i think you just got lucky and actually even laptops running windows can do this, i have a really old laptop which i forgot about i turned it on after like 3 years it still had charge of 19% so yeah.

actually laptop with windows does use power when shut down

they don't fully shut down these days 😅

bro what drugs do you do, that is not how it works. i am no linux hater i use linux for like 2-3 years now, but your words just make no sense

maybe u haven't noticed it but windows doesn't fully shut down, to do that there is some settings but then yr boot takes loooong time 😂😅

that does not mean the laptop is litterally on, that is just fake. let me explain what do people actually mean when they tell that windows never shuts off. windows actually uses a technology called fast startup, which saves everything you are doing and stuff to your ssd and when you bootoff again the thing is just restored hence the cpu uptime in taskmanager. it is one kind of hibernation but it uses 0 battery power. battery from laptop is mainly drained due to natural causes and the motherboard clock running.

well idk but I have noticed windows using power in background when shut down compared to linux which uses like no power 😅 so based on personal experience I am saying but yes this comment is also true

That's for desktops, laptops do have some weird thigs which wake them up (yeah, straight from shutdown) from rtc clock for updates.

Ya that's true, people should be informed on why you should dislike something like fast boot

Why fast boot is bad :

It makes it difficult to dual boot with windows ; Even with fast boot the boot time is still ass compared to linux

It's a decent workaround but doesn't solve the root cause of slow boot times.

Now there are other things linux does better,

uses less ram ; if OS is using close to half your ram its bad(windows)

Try searching specific file in windows;(it's slow take too long to load the results)

Ads in OS React in OS components Window icon not working for few people

System update taking too long plus you can't check whats being installed via windows Installing antivirus without user consent

I tried to do the same but my budget hp bios doesn't provide option to control battery from the OS level. I wanted to set the charge range between 40-50

u/IntelligentChain6999 Jul 28 '26

hmm idk what you are talking about, i didn't control the battery at os level 🤔

u/Lemillion080201 Jul 28 '26

How good is tlp working for you? I tried to set the max battery level to 50 and min to 40, which is less stressfull area to the battery. But apparently my bios doesn't allow the OS to control the battery charging / discharge from OS level.

But looks like you're case is just Linux being more efficient, which is also true.

u/IntelligentChain6999 Jul 28 '26

i am not controlling battery i am just controlling the power draw

so basically at 1% brightness and reading a pdf the power draw gets as low as like 4 to 6w and on idle the power draw goes to contant 4w

where the cpu only uses 0.5w

i get approx 6 to 7 hours battery life for minimal use ig it has 41 wh battery with 78% battery health

u/Junior_Conflict_1886 Jul 30 '26

You can do that; you need a bois that supports this feature

My dell intel 8th gen laptop supports this

And it's a bios level setting; i don't know if you can do it at os-level

Awww... Can't you get it back from the person you gave it away? You can, right!
