I bought my Mi Notebook Pro in late 2017 and loved the performance and build quality. However, many people including myself haven’t been receiving the 10 hours of battery life that reviewers such as Chris and LinusTechTips have been getting on their devices.
From the research I’ve done, it seems that Xiaomi has optimized the Chinese build of Windows that ships with the laptop and those under-the-hood changes do not carry over for those who do a clean install of Windows 10. Others have kept those optimizations by following Chris’ tutorial of upgrading Chinese Windows 10 to Windows 10 Pro and switching to English from there.
My question is if anyone can provide a factory image of their Mi Notebook Pro or knows how to obtain a copy from Xiaomi? It’s disappointing to see my Notebook Pro hit 10% after 5-ish hours of YouTube and web browsing while others can comfortably hit 7 hours of moderate usage.May 27, 2019 at 12:12 am #151993
+1. Agreed. Anyone know where to find this?May 27, 2019 at 3:35 pm #151998
http://bbs.xiaomi.cn/t-14031738 or www.miui.com/thread-11455594-1-1.html here you can get the factory image and the instructions to install it, but i don’t recommend installing it , because the original image of our mi notebook pro 15.6 is a single language version of windows , which means you can’t change the language or install any language packs.I know these becuase i’ve already tried it (you can upgrade from the chinese windows by having a windows 10 pro key,but its the same thing that i will explain without having to buy a new key).But if you want to use the program files, programs and drivers that comes with the offical image you can restore it by installing windows again.I’ve have done it and i didn’t that you can do this in windows 10.Basically what i did was I restored the original chinses windows as you can see on the websites above.Then I clean installed to normal windows 10.I had some problems and i needed to use troubleshoot to recover windows cuz a driver fucked it up.Booted to advanced settings and selected troubleshoot oprion and then system restore, then 1 option was available and i restored (it restores files from windows.old or the recovery in windows.old idk i forgot)
When it finished it was like when i first used the laptop just in english it had every driver, program and even wallpaper .. etc. , but i strongly recommend to backup your files from system partition in case someting goes wrong to prevent losing your important files.To tell you the truth the whatever version of windows 10 you use it won’t make that much of a difference from my personal experience than optimizng the windows yourself.I’m happy with my mi notebook pro battery life ,because i optimized it and it’s perfect.For exemple right at the moment i have 43 percent left and it estimates a 4 hours and 11 minutes till it discharged completely(I’m watching a stream in the meantime and i have 6 tabs open).So if you want some battery saving tips then i can tell you some if you’re interested in and i can also upload the factory windows file to gdrive if you need it ,because it’s complicated to download and download speed is slow on that chinese website.
(Attached some screenshot to prove that it worked)
(PS:Orignial windows had some modifications compared to normal for example i saw +1 option in advanced power settings where you could set something related to frequency which is not present in the normal windows 10 home , but it is unusable if you don’t know chinese.)

@Noel Horváth – Thanks so much. You are right about the license, but I do have an extra Windows 10 Pro license (they are also pretty cheap to get nowadays), so the Chinese version would be fine. You are also right that it’s difficult / impossible to download the stuff in your links from Baidu. so if you or someone else could upload the Chinese factory image somewhere else (e.g. Gdrive) that would be great! Thanks again! 🙂May 28, 2019 at 12:55 am #152005
Here it is https://drive.google.com/file/d/1IHbzkgf5WLhcOEHMwSGhF4zqrytVaywa .Upgrading from chinese to pro replaces the windows files , so the specific modifications won’t be there, right? Such a shame that single language windows version exists and sadly xiaomi uses that 🙁May 28, 2019 at 6:19 pm #152012
Thanks so much! I think the modifications should still be there as Chris uses the factory image with the English version and still has the battery improvements. Do you happen to know how I can install the .wim file? I’ve never used those, only .iso.May 28, 2019 at 10:58 pm #152016
Yes, ofc i can explain how to do it.First of all, you will need an USB to which you need to flash WinPE( http://down-ww3.newasp.net/pcdown/soft/soft1/wepe_64.exe ).After you have downloaded the program open it and click on the usb icon at the bottom then select your usb drive (don’t change anything else).Once it finished you should copy the .wim file to the usb drive.Boot to BIOS (press F2 at launch) and go to boot manager and at efi boot devices change order by placing the your usb at the top.Save and exit ,then you will be booted to the winpe os.Open the partition manager (red blue green coloured icon) and click on the sixth icon at the top under the text line.I have attached scs ,because it’s easier to follow the following instructions.This will wipe your system drive basically.After that open Dism++ program (cogwheels icon) at the top select the text with (R) then on the list select the fifth option above Compact.A window will pop up and for the 1. one select the .wim which you had copied to the usb and for the 2. one write X:\ (X=your system partition’s letter,ex.: write C:\ if your system partition is C … etc.) and don’t forget to check the 4th box next to windows text , after these click on the bottom left button.After that select the 1 option out of the 3.Once it has finished you can rebootto windows ,but remove usb drive and you are good to go.Change the key in settings/system/about, under windows version details select the 1. option and then you can change your key by selecting the text with the key icon.

Thank you so much! That worked just fine and I am on the Chinese version with English language pack now, updated to Pro via key change. Battery life seems better by about 1 hour or so!June 1, 2019 at 2:35 pm #152055
Good to hear that!October 17, 2019 at 7:42 pm #181860
I have bought a second hand mi notebook pro with a installed French windows version. Laptop is really good but I can confirm battery endurance is rather short.
I have a windows pro licence on it, so I’d like to give a try to your method to install a factory image of chinese windows which is supposed to increase battery life.
Could you please tell me if French language pack is available with the pro licence, or would it be only English ?
Thanks in advance. Regards.

The pro version of course has French , only single language windows versions have only 1 language.You can do that and you will have original drivers and a clean windows ,which i recommend debloating.But if you want to increase battery life, i advise you to read this:
+if you have problems with fans turning on during light usage, then use patched bios 603 ,so fans will turn on less frequently.Then you should be good.October 21, 2019 at 9:03 pm #181901
Thank you very much for your answer.
I could install factory windows image and activated with the pro license, and then installed French language pack.
I updated drivers with official ones found on Xiaomi website.
I can confirm battery life seems better, even running stock bios 603 without any special Windows optimisation.
I will have a look to your link, thank you.
For the moment I didn’t notice anything wrong with fans.
Thanks. Best regards.

Just a few more questions please…
My windows update stopped at 1803 version and says I am now up to date.
But the last available version is 1903 if I remember correctly. Are you in the same situation ?
Noel, when you recommend to debloat windows, do you mean to use the WindowsDebloater powershell command available on github ? Or maybe you did it manually ?
Thanks again. Regards.
