CONFIGURATION


Lenovo Legion Y740, Intel core i7 9750H, 17.3" 144Hz GSync, RTX 2080MQ, 16GB RAM, 1TB SSD, Windows 10, v1909 Build 18363.815

Windows 10 is up-to-date, BIOS is up-to-date, all drivers are up-to-date as per Lenovo Vantage.

I have only 5 items in startup lenovo utility, icue, onedrive, windows defender, phrase express.

Lenovo Vantage still says "The battery is in Good condition."

I got this laptop on 7th Jan 2020 and have been caring for it like a baby.



ISSUE



This laptop used to run ~3-4 hours on a fully charged battery. But since last two weeks, it is draining at 1% every minute, even when it is sitting completely idle, with no apps open in taskbar.



TROUBLESHOOTING



Booted up the laptop. It has 100% charge. Disconnected the laptop from power source and left it alone.


Kept moving the mouse cursor every few minutes so that laptop doesn't go into sleep mode.

Laptop lost ~80% battery in ~80 minutes.

I checked windows settings > system > battery > "See which apps are affecting your battery life". That says Windows Explorer consumed 84% of the battery!!




I then ran powercfg /spr and the generated report shows Explorer is only the 3rd highest consumer. Some "Unknown [NONE]" app has drained most of the battery and most of it went in "Loss".






I ran sfc /scannow and it "did not find any integrity violations."
I ran DISM /Online /Cleanup-Image /RestoreHealth and that too completed without any error.
I ran full system scan using Windows Defender and Malwarebytes. I also used Windows Defender offline scan. None of them found any threats.

And yet, my system is still draining at 1% per minute, when on battery.



HELP ME TO


Please help me identifying this "Unknown [None]" app. Or what is causing this battery drain?

Please help me fix this issue.

Failing battery or draining issues?


Bang! Problem solved! I also posted this in Neowin: Do I have a failing battery? Or is a program draining the heck out of it? - Surface Pro 3 - Hardware Hangout - Neowin Forums

I was suggested to reinstall the drivers. Device Manager didn't expressed any anomalies, but reinstalling the drivers yielded outstanding results. The device now lasted 4 hours and 23 minutes. The last hour and 23 minute was with the device playing music in Media Player Classic with the display always-on at 100% brightness and the volume 80%.

Thanks for everything *Biggrin *Biggrin *Biggrin

 

WP sync client draining battery


I cant find anything online what "WP sync client" is, but it is draining battery on my Venue 8 Pro. I have already tried to disable all tiles, and all background tasks. I dont have any phone sync app installed or anything. But still "powercfg sleepstudy" shows "WP sync client" as the main drain source.

 

Powercfg /sleepstudy report shows "Unknown [NONE]" appid which consumes more power
