Calibrating your battery:
Change Your Power Plan:
  • Right-click the battery icon in your taskbar.
  • Click Power Options.
  • Select Change when the computer sleeps.
  • Set both “Turn off the display” and “Put the computer to sleep” to Never.
  • Click Change advanced power settings.
  • Expand the Battery section.
  • Ensure that the Critical battery action is set to Hibernate.
  • Adjust the Critical battery level percentage to be as low as possible.
  • Apply the changes and save them.
Charge Your Battery:
  • Charge your laptop’s battery to 100%.
  • Leave it plugged in and allow the battery to cool down (this may take a few hours).
Discharge the Battery:
  • Unplug your laptop.
  • Use it until it shuts down and no longer turns on.
  • If possible, avoid using the laptop during this discharge process.
Recharge the Battery:
  • Immediately recharge the battery after it shuts down.
  • Once fully charged, your battery should be recalibrated.

If you notice big jumps, it means the battery is not calibrated. Charge it to full and discharge the battery to 0% until there are no jumps and the battery is calibrated.
