Decrease your Lockscreen timeout :

In this step, we will be choosing shorter times for screen and sleep setting to make our battery longer ultimately being more efficient. Many people look over this and don’t Realise how important this step is, I personally faced this problem it turned out that my laptop never went to sleep even when I was away for a long time. Do these things to make your screen sleep time shorter:

  1. Press Window Key.
  2. Search Power & Battery Options.
  3. Set the screen and sleep options to 15 minutes.
  4. Now every time your laptop or PC is idle for more than 15 minutes, the laptop will automatically go to sleep mode and make your battery more efficient.

Decrease your Refresh Rate:

Refresh rate is basically the rate at which your monitor refreshes, It is best to have a higher refresh rate monitor if you are a gamer, if you are using your laptop just to do your office work you won’t be needing anything above 60Hz. Nowadays, the laptop’s come equipped with displays that are 144Hz or 60Hz. If you are certain that your usage does not require higher refresh rates we can clock it down to 60Hz. This will help you utilize less of your battery resources and help you overall get a long-lasting experience.To clock down your refresh rate follow these rather easy steps.

  1. Right-click anywhere on the desktop to open display settings.
    Opening Display Settings
    Right Clicking on desktop to open Display settings
  2. Click on Display Settings.
  3. Scroll down till you see “Advanced display settings”.
    Scroll Down till you see the advanced display settings
    Opening Advanced Display Settings
  4. Check what is the refresh rate of your display currently, if it is above 60Hz Clock it down to 60Hz since our key focus is to leach out as much longer-lasting experience out of battery as we can.
    Clocking down Refresh rate to use less battery capacity
    Clocking down the Refresh rate
  5. After Clocking down the Refresh Rate to 60Hz. you will see an exponential change in battery timing’s since now your monitor is not consuming as much battery as it was consuming before.

Batteries perform way better in cold climates than in hot climates, make sure to sit in an open space where there is good airflow for your laptop, or maybe consider buying cooling pads that help you in two ways, one by keeping your laptop cool second by making your batteries drain slowly.

If none of these are working for you it is recommended to switch back to Windows 10 as continuous charge cycles can deplete your battery health really fast. That is going to make your overall battery and laptop less efficient. If switching back to Windows 10 doesn’t really fix your issue then it’s possible that your battery health is low it’s recommended to get your battery replaced or use your laptop when it’s plugged it.
