Battery drain issue

Below is another Microsoft resource that might help improve people's battery life:

System File Checker is a utility in Windows 10 that checks for problems with files on your computer. To run it, follow these steps:

• Make sure you've installed the latest updates for Windows 10, and then restart your machine. To find out more, read Update Windows 10.
• In the search box on the taskbar, type Command Prompt, and right-click or press and hold Command Prompt (Desktop app) from the list of results. Select Run as administrator, and then selectYes.
• Type DISM.exe /Online /Cleanup-image /Restorehealth (note the space before each "/"), and then press Enter. (**Note:**This step may take a few minutes to start and up to 30 minutes to complete.)
• After you see a message that says "The operation completed successfully," type sfc /scannow (note the space between "sfc" and "/") and press Enter.
• After you see a message that says, "Verification 100% complete," type exit.

-> Use Throttlestop in the FIVR section to undervolt the CPU try with -100mV  <-

For the undervolt continue lowering the voltage until it is not stable. Same for the iGPU start with -50mV and test until it is not stable.

Make sure your battery is in low power mode when disconnecting it from the AC to ensure the longest battery life.

Yup, same problem here. They are all doing it. I tried all the suggestions and it doesn't matter. The machine is very powerful, for what it is, but the battery cannot keep up. I am only getting about 4 hours. I have to keep an external power bank or the charger handy every day.

Also, if Microsoft claims 10 hour battery life then it should get 7-10 hours out of the box no problem without any tweaks. Very misleading. I love the experience of the device but the battery life is like a thorn every time I am getting work done.

I am getting 7.5 to 8 hours of battery life.  Doesn't matter if I am just watching YouTube videos, or doing work using Microsoft Office apps.  Also, my Surface Pro 7 (i5, 8 ram, 128 ssd) was not new, it was an open-box excellent condition purchase from Best Buy.  Anyway, here are some of the things I did to increase my Surface Pro's battery life:

1. Made sure all background apps are always turned off.
2. Use Microsoft Edge Carney browser (Google Chrome is a big drain on the battery).
3. Unless I am using it, I always have the Edge Carney browser closed. 
4. I keep screen brightness at around 50%-60%.

5. Battery saver mode is activated as soon as the battery's charge goes below 100%.

6. Applied some of the tips from this webpage, "Ultimate Tips to Max Out Microsoft Surface Battery Life" (https://surfacetip.com/)

7. Instilled this driver/firmware update,  SurfacePro7_Win10_(https://www.microsoft.)
8. Most importantly, uninstalled this driver/firmware update, SurfacePro7_Win10_this driver/firmware update increased my battery's life by around 2 hours. 

Hope these things work as well for you as they did for me...

Here is my response in another thread: https://answers.microsoft.com/en-us/surface/forum/all/microsoft-surface-pro-7-battery-life/1ec34164-e79a-4645-9fc0-a2cc97ee47e8 

This seems like a great patch solution for people that are a bit techie & savvy. I have not tried this myself and will look into the firmware piece, as I really believe that this is a software issue as people have received replacement units and still have the horrible battery life. This is why I have not sent for a replacement as I have no other issues with the hardware and reset the OS twice to make sure the setup is ok.

Between points 1,3,4 &5, these are not normal things one should have to do to extend battery life. On number 2, indeed Google Chrome is a hog on battery (depending on how it is setup ie: extensions, adblockers, 3rd parties Add-ons/EXT,etc). There is the new MS Edge Chromium, which has the same issues in my opinion. The regular MS Edge browser was not so bad, but not a fan for me or others out there. There are other choices/options in this regard anyway.

Number 6, I had done most of what the suggestions are mentioned, installed BatteryBar, create a new PowerPlan, Cortana for me is completely off (i just don't use it at all). As for the rest, it mentions to turn off practically everything... It is unacceptable to have to do all this to reach a proper & respectable battery life. What is the point to have a tablet where most of the options needs to be off to work...ridiculous!

Unfortunately, this is not the right or permanent solution. Microsoft needs to fix the issue at the core, either software or hardware. The latter will obviously not happen due tot he way of the design. But nevertheless, if they claim they had 10.5 hours in the lab, there is no reason that we should not get a respectable 6/7 hours minimum out of the box!

I truly believe this is a software (Firmware) issue as I mentioned in my previous post above.

My new work tablet, Lenovo, gave me 6.5 hours with absolutely not tweaks (confirmed with IT dept.) and cost $500 less!! WTH!!. I would play movies, surf, work, etc....and get great battery life. (the company replaced all the surface tablets (that was the only tablets we had) because of the battery life issue). good way to lose business customers hey MS? 

MS keeps putting their head in the sand and ignoring the issue altogether as we have not seen any significant fixes for this issue in years, meaning all other Surface have had battery issues (big & small).

Microsoft, you need to fix it! Plain & Simple!!

Update 7/14/2020:  After instilling the Windows 10 2004 update my battery life has dropped to 6 hours and 30 minutes of continuous YouTube viewing (50% brightness, battery saver and Wifi on, Bluetooth off).
