How are things with autonomy on a laptop in Linux?

Question

linux

Hello, please do not kick, Linux has been an admin for a long time, but lately I have been using Mac or Windows on laptops.
I recently bought a laptop with 4 gigs of Acer Swift 1 sf114-32 RAM, sometimes it lives under Windows for 12+ hours, but I ran the same ubuntu, it shows 6 hours. True, I also launched livecd on 18.04 (now there are already 19), maybe something will be installed and configured during installation.
I just wanted to know if it is possible to squeeze as much battery life out of a laptop as out of Windows? What utilities or ready-made configs with power plans are there?
Basically, the work will be when the outlet is not available.
Or is it worth continuing to bother with WSL/WSL2?

Answer 1

under Windows sometimes lives 12+ hours, but launched the same ubuntu, shows 6 hours

Traditionally crooked ACPI support, a very old problem. There are simply no (normal) drivers for this particular set of logic, so not all power saving functions are involved.
No, the systems will be almost identical.
Absolutely not. It didn’t start right away - hammer it. To clear your conscience, you can google "linux cpu freq scaling" to make sure that the processor does not thresh at maximum all the time.
The perfect way out.

Answer 2

Or is it worth continuing to bother with WSL/WSL2?

A very inconvenient replacement with an additional set of annoyances.
Is a Mac right for you? I do not like it, but based on the task, this is the best choice: both standalone devices and Unix type.

You can squeeze out more than on Windows, but the hardware must be selected. When all the drivers are there and everything is fine, it makes sense to play with fine settings, there will be a profit (I had an hour more on my Thinkpad X220 on Linux than on Windows, if you just sit on the Internet to read articles for example).
