Here are the results. Battery draw on the Lenovo varies wildly from second to second, the numbers on the Huawei are quite stable.
I am running nothing during the tests. Onedrive is open but has no new files to sync.
Sorry, the battery wear is backwards. the 9.7% are for the X1, the Huawei shows 0.1%.

are you just another poster creating the mess that stops the problem being solved?
bananaman we are talking about expensive bits of kit and if you are just creating noise with your random posts please stop.

Those up to 15 hours, must be read no more than 15 hours of battery.
Even if Yoga will run 30 minutes on battery, above statement will be true : it runs no more than 15 hours, and it runs even no more than 100 hours on batter, no more than 1000 hours on battery. Because it is just 30 minutes.

I agree I am probably too direct in the way I write.
The bottom line for me is I paid £2200 ($2900) for what I thought was the best I could possibly buy.
I do lots of travelling and currently I am lucky if I get over 3 hours use at low screen brightness using word and wifi.
As I am almost tethered to a power outlet what I have in reality is a desktop computer. I feel very let down and lied to by Lenovo and will probably sell my X1 on ebay at a great loss and will stick with my Dell Latitude 7390 2in1 that is advertised at 12 hours and gets a solid 7. When the next gen processors come out later this year I will get another Dell and pass Lenovo by.
My history with Lenovo goes back a long way T40 - T43 - T60 - T420 - T520 - X1Y – Dell 7390

For fun and to add more actual data to the thread, below is a graph based on data in the Windows battery report. Green is my (fitted) battery capacity, which has dropped from 54Wh to 47Wh over the past fifty weeks. Blue is the estimated runtime for that week, which is based on average off-AC usage if I understand that correctly.
The battery life has dropped quite a bit faster than the battery capacity, so either I'm using the laptop more intensely (brighter screen maybe?) or something else is going on. The bad news: over the past half year of ownership I've been getting the equivalent of 4-4.5h battery life, corresponding to a typical power draw of 11-12W. That's pretty bad, and a lot worse than I thought!
Edit: so it looks like my results are similar to those of YOGAbbagabbro (4.5hrs, moderate use) and drjochen (average 11W at 50% brightness, low usage).

I have the high-res non-HDR screen on mine. I got mine very early and the HDR screens weren't available yet. I get about 8 hours on mine, but I keep the brightness pretty high. I never compared, but I would expect a 500 nit screen to use more power than a 300 nit screen.

Did anyone else see a sudden drop in battery life like the one I had in week 18? (see two posts up) I tried to see what I installed that week, but unfortuntaly it happened to be a LOT of stuff because I just got my eGPU dock and WMR headset. Things that were installed:
- SteamVR (including over 400 DLLs.. good grief)
- Windows Mixed Reality components
- Vortex (mod installer)
- NVidia drivers (including at least 55 NVidia DLLs, some of which have a name including "telemetry")
All of these seem pretty good candidates for leaving some power hungry service / background progress. Wish I could figure out which one of these is the culprit, if any.

Maybe someone can suggest (trustworthy/secure/vetted) software/app to analyze power usage. I'd personally be interested in a list of options that would include different facets like heat, cpu/gpu/memory (etc), app, background app, etc. and including tools not affiliated w/Lenovo or MS. Not that I'm dubious of their tools, but it would be good to have some options of explicitly not-affiliated for xreference. @joesixgig, I like the hands-on approach you did, i'll prob fool around with that later.
I've also noticed more seemingly high heat issues lately, always while plugged-in, often when at full charge but plugged. I use the Battery Threshold fn whenever possible, usually set at a range of btwn 40-50. I'm also lately beginning to sense it's a bit more 'bendy' again, something I'd started to notice previous to sending it in for the heat/keyboard (couple other) issues. My guess is as it gets hot for a while it generally gets a lot more...'pliable'...until unplugged/cooled. Not ideal when you're using it for blocks of time plugged in at school then throwing it in a bag w/books and walked across campus. If anyone is experiencing casement/chassis fitment issues (mine were an obvious gap btwn lid/body on the right side along w/laying uneven on a flat surface) I suggest you monitor how hot it gets relative to percieved 'warping'. I'll add to my knowledge the sense of warping hasn't seemed to result in any change in functionality - but I expect that if it's not in my head, something could be affected.

Oh, wanted to note I don't have Steam or Vortex components installed. I prob have default WMR and some Nvidia drivers for the external gpu.
