Why battery of Acer Iconia Tab W1-810-15A2 discharges despite plugged in after Windows 10 upgrade?

My Acer Iconia Tab 8 W1-810-15A2 tablet with Windows 8.1 was upgraded by Microsoft online to Windows 10 for FREE, Great! BUT.... After upgrade, the battery now discharges DESPITE being plugged in. WHY?

BUT IF I shut it down, it CHARGES as usual.

Should I go BACK to Windows 8.1? OR should I re-install all drivers and there is a BIOS upgrade as well, I noticed in the Drivers & Software section of Acer.com.

Did anyone have the SAME problem? I GOOGLED and it seems OTHERS have3 encountered the same problem,not only with tablets but laptops, notebooks, etc.

is this an Acer deficiency OR a Microsoft BUG, to put it simply ???

I also read the experience of a user with SAME problem and he DID successfully went back to Windows 8.1. PROBLEM WAS that discharging battery problem despite being plufgged in STILL WAS THERE? ACER BUG, I guess.

ANY SUGGESTIONS, ADVICE? Greatly appreciated!

I'd guess some of the power settings are not optimal for power. Check for the chipset and networking settings to see if they are shutting/slowing down approriately for your use.

will check that all out. thanks.

But strange that when I googled this situation, I see many are complaining of the same when they upgraded to Windows 10, not only on tablets, also notebooks, laptops etc.

The power settings seems to be limited in choices as well.

I have heard anecdotes of others who have seen changes to the power settings. It may be that some chipsets have the issue and others do not, or it may be some configuration changes made to the stock settings in the previous OS trigger the issue...
