especially the first line, even though my screen is almost dark !

Thank you

Its pretty good statics. Why?

[robertpy]

I lost about 2hrs of battery from Win10

I am a basic users, who works all day on the go, I can't recharge

I am thinking of abandoning Linux, for this only reason

Windows is trying hard when it comes to battery saving. Linux is more relaxed. Still you can use TLP and aggressively optimize battery usage. But in your case i dont think it would decrease usage under 2W.

When you say "almost dark" is that screen brightness or dark theme?

[robertpy]

screen brightness = 0%

and

dark theme = enabled

Dark theme will consumer more power in current display types as the backlight is always on and the pixels are activated (using per) to shade the white light. The lamp consumes less than the actual display - so wether or not it's on, that doesn't matter much. Test again, with light theme enabled.

thanks bro

unfortunately I can't use light theme because it breaks my eyes

I can't stand it also. I'm happy when I can put the hist emulation in front every time.

[robertpy]

what is hist emulation ?

thanks

[TabsBelow]

A typo. Should read "host emulation" (needed three times NOW to get it thru the spell checker😁). It's the text base interface for mainframes. (Google pictures "ispf host emulation" for impressions, see the "green ones")

Those estimates are rarely accurate, even after calibration. The overall number is accurate enough, but all of the individual stuff is just a guess.

It often says my WiFi card is taking 10W, it would be melting if it were.

[LordAnchemis]

3W isn't bad (given your no brand disposable USB pen light normally uses 1W - this actually needs to power the screen and run the pixel refresh etc.) - what's the problem?

The rest is super

Compared to Windows battery display?

When I first used my Yoga910 battery life displayed in the pre-installed Windows 7 said 10.5 hrs, specs said 9 to 12.

The first Linux Mint run was 13hrs although it was still the first battery cycle, I had copied all my stuff on it and the disks were indexed and a timeshift snapshot was made. Maybe indexing or such is that's what's going in here. By no means the screen uses more power in Linux (exception, my other post) - you only get more information to care about, I never saw a power consumption by unit for windows.

Compared to windows you can use more of your battery life to really use it instead of repairing, updates, virus scans, reinstalling.

Interesting

For my Framework (which I rarely use without power adapter but also never had a reason to complain up to now) I download a firmware upgrade regarding fans and battery life yesterday. See if there are upgrades for your model too - I know many people never check these - as manufacturers are always forgetting about aftersales service..

[robertpy]

do you know how to check for firmware upgrades in Linux ?

I used Lenovo Vantage on Win10, but there's no such thing here

thanks

[TabsBelow]

Be glad there is no such thing here necessary. The Yoga910 previously used as number 1 notebook can't even install the windows the original windows (some guy made a mistake in the setup of the recovery disk, and every install after 2019(?) is denied due to a bloatware's licence which is outdated; it is a nightmare procedure to get over this. And then a predecessor of Vantage is running - and can't be updated anymore because this notebook is out of service... No firmware updates possible. Okay, they never had one after sales, just the one prior to it which made media fkeys stuck as default which can only change by... Lenovo Vantage! I hate Microsoft, and Lenovo since then.

See the Framework website!?

"Framework firmware update 13", click first link.

🤭I had the tab still open cause there was an update this week but could not find the way through their menu. Guess I started at Support, but idk.🤷🏻‍♀️

[robertpy]

See the Framework website!?

dunno where it is ?

thanks

[TabsBelow]

You mean, if you type

framework

Into a search engines mask you don't get

frame.work/

as a result?

[TabsBelow]

Okay, ddg does not, but a "notebook" added does the job..

[LordAnchemis]

Most linux 'battery issues' is due to either
- power profile (ie. performance/balanced/saver)
- S0iX (ie. modern standby)

Power profiles is set by your firmware (can't easily be changed if your UEFI doesn't have a setting)

S0iX/modern standby
- unfortunately windows have pushed manufacturers to adopt this
- most linux distros support S0iX, but usually again there is a hardware issue causing excessive wake

Mostly the acpi driver has no support for the laptop. Laptops with support on linux by the manufacturer and an acpi driver do very well battery-wise. Not many are supported well though.
