battery drain issue after windows 10 upgrade

Hi! I just recently upgraded my girlfriend's laptop to windows 10 as it is still running on windows 8 pro and I just recently installed a new RAM and when I boot up the device, the user available memory is only about 2GB so I did troubleshoot it and led me to doing a format to the device so instead of installing the same OS, I decided to upgrade her device to windows 10. after that, her device will shutdown at about 50%. sometimes it goes about 45% but it won't go below that. I already change the battery plan, put it on battery savers, disable the Intel Management Engine Interface, disable the fast boot, but it's still the same. I already check the the battery health life using the "BatteryInfoView" Utility tool and it's at 44%. The device is an Acer Aspire E5-471. What should I do?

By the sound of it, replace the battery, that is my first thought after reading your post.

I believe the issue to be unrelated to Windows 10, and if it is indeed a problem in the battery I'm surprised it didn't happen in Windows 8 as well. Many times the thing about shutting down sooner than anticipated, at 50% for example, has to do with the way the battery controller (within the battery itself) is reporting a wrong charge level.

Say the cells inside are at 10% of the capacity they're able to hold yet the controller reports the battery is at 60%. As soon as the juice runs out the power is cut.

I can't say for sure that's what's going on there, I'd have to examine the unit and its battery outside of the laptop, but try what some people call re-calibrating" the battery. It's something that's generally unwise because you shouldn't let lithium-ion based chemistries deplete themselves fully, but it can help when an controller is reporting the wrong data.

You state that BatteryInfoView lists the batter being at a health of 44%, meaning it can hold 44% of what it was designed to; and assuming it is the original battery of the laptop I'd say the designed battery capacity is the actual battery capacity when it was new (3rd parties tend to hack that info too).

So... there are different ways to deplete the battery and then fully charge it. I think there is no inactivity timer in the BIOS of the system so you could just turn the computer on, press F2 to get into the batter and let it sit there until the battery is flat. When the computer shuts down, try to turn it on again and get to the BIOS in case it had shut down without completely depleting the battery.

In any case, once it's flat, plug the adapter and leave it be, turned off, until the battery is fully charged. Then turn the machine on (still with the power adapter connected) and fire up BatteryInfoView, see the values it reports while the adapter is connected and take a screenshot to post here. Then disconnect the power adapter, wait for a minute or so and the charge level should change, take another screenshot at this point.

Post them both here and we'll see what's up, but as I said, it seems just like the battery is on its way out and in need of replacement.

hi! Thank you for your response. I also tried calibrating the battery and yes, there's no inactivity timer in bios. I also tried updating the bios, and all of it's drivers and nothing still happens.
