Under Battery Runtime, the WiFi v1.3 test result was 519 minutes. Though, the Update stated that "[t]he FHD model of the ThinkPad X1 Carbon 2018 (otherwise identical components) lasts around 10 hours (601 minutes) in the WLAN test".

Questions

1. What did the WLAN test entail?

2. What is the difference between the WiFi v1.3 test and the WLAN test?

3. Which intel chip did the FHD model of ThinkPad X1 Carbon 2018 have in the 601 minutes WLAN battery runtime test: i5 quad core or i7 quad core?

4. What was the WiFi v1.3 (battery runtime) test result for the FHD i5 quad core model of the ThinkPad X1 Carbon 2018?

The problem I have with the x1 carbon is a history of issues that have occured after purchase.  Screen flairing, burn ins, monitor issues,  power off issues etc.  Repeated returns and repairs only to have the same issues happen.  Don't believe me, just read the public posts about the carbon and repair returns.

I do a lot of programming and compiling with thin and light devices.  Compilations can be very demanding and prolonged.  I also run test cases of my codes on my machine, which are also very demanding on matrix math.  Just as well, while I compile and produce data, I don't sit around gawking at the screen, I do other things with my laptop like watch stuff or read.  Having a device running this hot on my lap is not okay to me.

I also use Macbook Pros for development and debugging, they are much cooler.

Cinebench on a loop is much more strenuous than compiling code, though compiling will still get it warm probably.

I'm comparing the X1, razer stealth, XPS 13, and a couple other thin and lights that have a Thunderbolt 3 port for use with a Razer Core X. I like the idea of having a thin and light I can use for work and plug in TB3 at home for some gaming. Fan noise is one thing I despise.

I was much more concerned with the fact that they complained about the high pitch of the fans on this X1. But yet in the Razer Blade Stealth review  they do not complain about it much at all. But if I put the Razer Blade Stealth with the i7-8550U and this 6th Gen X1 together on the fan noise comparison table, the Razer has a higher DB output at every frequency range in their graph. The statement doesn't jive with the data. Which one do I trust, or was the reviewer of the X1 just used to notebooks that don't make any noise at all when pushed hard? I'm ok with some fan noise, I just don't want it to be "gaming notebook" loud. The appeal to me of using the Core X and a thin and light with a good-enough CPU is

1. The Core X is quiet, can also get a pretty quiet 1080ti. (MSI X)
2. Battery life on these is good to stellar, and they all weight 3lb or less.
3. I expect the fan to be quieter on these than a typical gaming notebook as the CPU is lower wattage.

The X1 was intriguing to me since it had a 14" display instead of 13.3".. but if the fan truly is high pitched under any semblance of CPU load that would be a non-starter.  I'm also not super jazzed about the CPU vent being on the right side. The design so that the CPU is going to vent it's heat on your mouse hand is questionable. My guess is they thought it was better to do that than have the dock/dongle for wifi on the mouse side. It's too bad they couldn't have found a way to vent using the hinge or the rear.

Why are people so concerned about heat?
More heat indicates the device is working hard for you and it is dissipating that heat to the environment (which should be a good thing, as opposed to a device which is repeatedly throttling down).
These Ultrabooks only go so far, if you have any serious computation work to do then its best to offset those loads to a desktop instead. I still like the Core-M as a mobile cpu for these sorts of devices, even Ultrabooks. I recently tried out a 7th Gen.  Core-i5 Kabylake and the fan is off much of the time. So efficiency seems greatly improved. However don't expect too much from an Ultrabook. It has its limitations.

Is it necessary to turn off the laptop and to disable the battery when changing the micro sd?
The problem is that whenever you want to change the micro sd, you also remove the sim card. And the manual says that before removing the sim card, you have to go to the bios and disable the battery.

I just got one of these as my work computer.

It has the 2560 x 1440 display. I believe it's the HDR / dolby vision as the screen is glossy. How can I confirm that though?

Also, does anyone know if the battery is removable?
I bought one of theses too. Mine has a HDR display as well. But, it does not support HDR just yet. It will be supported with the Windows 10 April update and a video driver update. "LEN40AE" should be the HDR display hardware ID.
The battery is not removable. I recommend getting the Warranty upgrade with sealed battery for three years. It gives you one free battery replacement. You can also send the laptop to Lenovo and get it replaced if there is something wrong with it. Hope this helps.

@Rational Guy

The Macbook Pros are pretty good thermal and performance wise.  Max bottom temperature under load is 43.9 degrees C as reviewed here, which is barely above body temperature.  It also doesn't throttle under load according to this website.  Costs an arm and a leg though.
However, the carbon fiber body of this laptop doesn't feel hot to touch. Which is unlike metal bodied laptops. Besides, this laptop won't reach that peak temperature when it's on your lap. It runs on a smart cooling mode. When it is on your lap, it runs on a cool mode.

With those temperatures, you can't use this laptop on a lap for any serious work.  So what's the point of this thin and light laptop ?
It does not get that hot when the laptop is on your lap. It has a smart cooling option. It runs on the cool mode when the laptop is on your lap. The fan rarely comes on when it's on your lap. Besides the temps go that high only when it's in max performance mode. You can tune the CPU using Intel XTU to configure to your liking as well.

50 degrees Celsius on the surface.  Halfway to the boiling point.  Nice.
It goes up to that temp when it's in max performance mode.

To hell with these laptops, we need Ryzen laptops being benchmarked. Where are alll the reviews? The only one we got to C actually perform in it's full potential was the Ryzen 5 2500U what about the rest?

I second the request for 16:10 screens across the X and T series Thinkpads.  Didn't Lenovo get the message from what people asked for in its 25th anniversary model?  And the subsequent complaints?

16:10 screen.  Get this done, Lenovo.

Thanks to your review and your complaints about how *hot* such a *thin* laptop can get under *continuous* load, Lenovo has locked the device to 33W on the new bios release.

Are you happy now?

I have the T480s and I managed to undervolt slightly and overclock slightly to get ~750-760 Cinebench R15 score. I think notebookcheck's numbers are a bit off? Other users on r/thinkpad report similar scores with X1C 6th gen using similar undervolt and overclock. The i7-8550u is a VERY capable CPU

But why in lenovo configuration is - 14" HDR WQHD (2560 x 1440) IPS anti-reflective, anti-smudge, multi-touch with Dolby Vision (500 nits).

Is it anti-reflective or not? Something was changed?
