Windows 10: Why does my battery rapidly drain when my laptop is in sleep mode?

Sometimes, when I close my laptop's screen and it goes into sleep mode, the battery will go from 100% to under 10% in just over an hour. Why is this happening, considering that the battery is draining around 5x faster than usual and whilst in sleep mode? My product is an acer aspire A515-58M

Sleep Mode has never been efficient. In all my years of using laptops, I've always just turned them off and on. Battery drain is normal for sleep mode. Some people have had issues with the laptops not powering off completely and draining the battery, but if that's your issue, there is an easy fix. You turn off Fast Startup and check a setting in Device Management under Intel Management Engine.

 

Battery drain in sleep mode

Hi,

I have an Asus UX430U and it's draining the battery when in sleep mode.

The cpu is running when in sleep mode. I suppose it should not happen.

The laptop is getting really hot and the whole battery goes off in around 1 hour in sleep mode.

Thanks to anyone who could help.

even mine has a slow battery drain, using Win 8.1. Even when powered off, not in sleep or hibernate, but off. It still uses the battery to keep the clock going.
Turn off fast start, as suggested, hibernate over sleep as it uses less power, and if you aren't going to use it for several hours, shut it off.
