Laptop Battery Issue while using Manjaro

I have installed Manjaro XFCE in my Laptop, that also has Windows 8.1 in a dual-boot format.
Now, some information about the said Laptop: OS: (win8/Manjaro), (around 4GB RAM, 500GB HDD; Ports: 2USB2.0, 1USB3.0, Network: Ethernet/Wifi/Bluetooth, Processor: Intel i3 4th Gen),
Dell Laptop Model: Inspiron 15.

The issue is that the Battery DISCHARGES at a rapid rate, when using Manjaro, unlike in the case of Windows. Why is that? And, is there any way to Resolve this Issue?

Battery Model as Per Laptop Specifications:

And the following is the Battery information shown on Manjaro Terminal.

sudo tlp-stat -b

Hello @hisonny :wink:

You could check with powertop if there is a pci/usb device which drains the battery. Sometimes it is the webcam…

Also TLP can be used to manage power optimizations.
