Change Critical Battery Levels on Windows 10: Users are unable to change the critical & low battery levels below a specific point and if you got a big battery then you are not able to utilize your battery to the optimum levels. You won’t be able to change the critical battery levels below 5% on Windows 10 and 5% means close to 15 minutes of battery time. So in order to utilize that 5 %, users want to change the critical battery levels to 1%, because once the critical battery levels are met the system is automatically put into hibernation which just takes close to 30 seconds to complete.

Low Battery Level: 10%
Reserve Power: 7%
Critical Level: 5%

I thought that you were talking about the overall lifespan of the battery. For those of you who are looking for the exact same thing, you can check the overall lifespan of your battery on the control panel of your manufacturer. Mine is Dell Support Assist. A red warning should pop-up in the case that your battery’s lifespan is on critical levels.
it works for battery scheme, but what would be the command for critical level when plugged in?
It doesn’t work for me under 5%. I just get the message:
The value specified is malformed, or is not within the range of the target power setting.
For the ‘plugged in’ AC setting (the 2nd command), you should omit the ‘%’ symbol at the end, so to set it to 1% use:
powercfg -setacvalueindex SCHEME_CURRENT SUB_BATTERY BATLEVELCRIT 1
