Ubuntu – Ubuntu 18.04 Battery issue

18.04batterypower-management

I am having Acer machine currently installed Ubuntu 18.04.
After I fully charge battery it works fine till around 45 – 50 % but after that it suddenly drops down to 1 – 2 % and notification popups of saying that battery is critically-low, your PC is about to hibernate.

If I plugin and recharge till then same thing happens, but If I continue using without plugging in then it continues for around 30-40 minutes even after 0 % battery.

Is there any issue with power management of Ubuntu OR it is the battery behaving weirdly.

Best Answer

I figured it out, actually it was battery's problem but it is also true that somehow Ubuntu drops our battery capacity comparing to Windows
