Good battery, good customizability, but I'm wondering: - Who is actually producing these? Are they resellers? For whom? - They mention TuxedoOS. Why? Can you have the same experience with a vanilla Debian or Arch? - Customs costs. They may inflate the price quite a lot depending on where you are

Their website provides good enough information I believe:

- They only mention production in Germany. Their "Why Tuxedo" page[1] does seem to imply that they are building most of it themselves.

- They mention TuxedoOS for the same reason System76 mentions Pop_OS!: because they made it. I would expect it to work with any one of the OS included in their WebFAI[2] pretty well[3], which by the way I believe is actually sent with the laptop.

- Their FAQ might shed some light here[4] depending on where you live. It's pretty much the same with any brand I know; maybe you have had a different experience?

My lenovo X220 has the most insane battery life I have ever had.

I had the 9 Cell battery (compared to the 3 cell) with the additional backpack chassis battery that clipped on below.

Just by itself the 9 cell was good for close to 10 hours.

Extended battery was: 64.38Wh and the extended 9 cell was 94Wh.

About a decade down the road, I still have about 50% battery life left in it at max charge and it still holds its own on an all day outing

When I think of my E-Bike battery of ~400Wh that can keep going for ~100km (admittedly, with some assistance), I'm surprised this laptop can only go for 16h on that. The energy required to move 80kg (me+bike) 25km is significant.

Well, look at the power outputs of bikers. 100 watts can probably get you to 15mph in flats / no headwinds. so that.... well, 400 watt-hours for 60 miles! Meanwhile, gaming rigs are coming with kilowatt power supplies now, maybe even more. Laptops try to be more efficient, yeah, but 100 watt-hours in sixteen hours is 6.25 watts sustained. Did I math that properly?

I mean you can check with this tool[1] I discovered while wondering for myself. I gave up halfway through though.

I'm typing this on my 1 year old Tuxedo InfinityBook (S 14 Gen6, not the Pro). Now I'm definitely spoiled by the Lenovo X1 series, but I'm not happy. The hardware is a rebrand from clevo-computer.com - some minor spare parts can be had from there. The system is VERY prone to overheating, the fan is noisy. They claim the fan noise is "not annoying" which is only true in the short term. I have opened up the bottom shel…

One more nit-pick: the screen is polarised the wrong way. You can't see anything when wearing polarised sunglasses (those are always oriented so they filter out the polarisation of water puddles).

Isn't it a searing indictment of the entire Intel laptop chip lineup that a MacBook Air M1 has half the battery capacity (50Wh) while giving easily twice the battery life with as good or better performance -- and with no fans!

It's also a searing indictment of Linux. I get less than half the battery life on my Alienware AMD laptop under Linux than under Windows. I don't know what Linux is doing wrong here, but it is not energy efficient.

It's not just with Intel. Apple has 2 years on Qualcomm as well as their phones also have significantly smaller batteries compared to their Android counterparts.

That checks out, 6W is about the power used by an average laptop. Best in class ones are about 3W.

Does that laptop support Linux? If not, I'd expect a key reason is simple; it likely is not using all of the power saving functionality supported by the laptop. This might include things like S0ix, throttling, proper sleep states, etc. There's a lot of factors going in, and I think by and large it is not actually an endemic issue with Linux itself. Consider for example that x86 Chromebooks have no issue fully exploiting modern x86 power saving features and getting good battery life.

For me it's the exact opposite: I can't get the Linux battery life on Windows without turning Windows down into a stutterfest. Windows is also noisy as hell.

It all comes down to driver support. If you manufacturer doesn't have proper drivers, your experience will suck. It says a lot about Lenovo that open source Linux drivers work better than their proprietary ones, but that probably comes with the territory if you combine Intel and Nvidia.

I have an X200 with a 9 cell battery, bought new a while ago, but I think 4h max is what I get, if I lower brightness and only run Emacs or so. How do you manage to run 10h? Does the X220 somehow use less?
