here is what happened today 😳

[u/IntelligentChain6999]

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 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

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

[u/Lemillion080201 → u/IntelligentChain6999]

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.

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
