If you’ve read this far in the guide, you obviously haven’t managed to improve your PC’s battery life yet. You have no reason to worry because you will most likely be able to solve your problems by performing a procedure known as battery calibration. Are you wondering how to do it? I’ll explain it to you right away.
For starters, turn on your laptop and let it download completely. Then put it back on charge, wait for it to charge 100%, leave it on charge for a couple of hours and repeat the steps I just indicated again (possibly 3-4 more times). If all went well, you should notice a significant improvement in the battery life of your laptop.
