Hi, I am currently using HP omen 15 laptop with POP os linux. But battery life I am getting is really poor. I tried with few other flavour of linux as well like Ubuntu, Mint, Mx Linux etc but getting almost similar battery backup in all. Could anyone suggest me a better setup where I can get a decent backup and support. I think that poor battery backup could be due to manufacturer don't have good support for linux. Does anyone already faced such situation and got a better OS and manufacturer combo. Or aware of laptops suited for linux system??

i'm using linux on my asus zephyrus; with the xanmod patched kernel. seems to be giving me about 7h battery life (maybe 20h if on sleep/standby)

I have rarely seen a laptop providing good battery on any Linux distro. It is almost like a myth. I so wish it had a battery life like Mac, but it doesn’t. Macbooks are the only good option for devs to get a great battery life.

Linux doesn't have proper sleep mode. Hence the battery drain.

You can try powertop and see if it reports any issues. Optionally also laptop-mode-tools and TLP for ThinkPad. I was using a ThinkPad for nearly 1.5y before I realised that my laptop's fingerprint reader was draining power even when it's in sleep (it doesn't have a Linux driver). All I had to do was disable the device from bios. 2x battery life (5-6h from 2h, I have an old ThinkPad)

Linux doesn't have proper sleep mode.

This is just a modern myth. 🙂 Sure, there are laptops that don't work well as the manufacturers did NOT configure them properly. (even going so far as to disable in the BIOS the long-supported S3 standby mode that was supported over the last decade, in favour of the half-baked "Modern standby" mode pushed on them by Microsoft ) Due to the vast variety of manufacturers and hardware, compared to Macs, it does require some tinkering in software (Driver, BIOS, config-files) to get any Laptop working perfectly with the Linux distro of your choice.

Hi @chilly-rocket-77832, could you share some resource how to tinker a linux to work perfectly for your laptop hardware. It would be very helpful

work perfectly

"perfect" depends from person to person. and since Linux is a lot more open to tinkering there isn't one size fits all. For example, someone may prefer instant power-up even if that means battery life is lower. -------- In the context of this thread, to get the best possible battery backup what Rohit mentioned above is the way to go. run

powertop

see what's consuming battery, disable it if that's something you don't use, re-configure it if you use it. Here's an example - https://www.tecmint.com/powertop-monitors-linux-laptop-battery-usage/ Also look in the system (syslog) and kernel logs (dmesg) for warnings/errors and check how to address them. (reconfiguring/upgrading/disabling the offending library or driver) Also, have a look at the various options in the BIOS. Understand them by searching/reading about them online. Backup critical data on the system and modify them one-by-one to match your requirements. (eg. some laptops do support S3-standby, but need to explicitly choose that in the BIOS that ships with default "Modern-Standby" as manufacturer expected MS-Windows by default) At each step, searching online for parts of the warning/error message, along with the name of the part, the driver version and the name/version of the Linux distro should usually land on how someone has already fixed/worked-around the issue. _(worst-case, can always ask on the distro forum or some communities like this_🙂_)_
