Dell G7 7590 suddenly shuts down
I have had a Dell G7 7590 for the last three years. Since the last six months, even though the laptop still has 40–50% battery life left, I have noticed that it abruptly shuts down owing to low battery. Even though I don't use my laptop very often, my battery life has significantly decreased to 15 to 20 minutes.
I only use it for personal skilling and sporadic browsing. It's not like I play games or watch videos, but this is what it has come to. I thought there would be an improvement after upgrading to Windows 11 yesterday, but nothing has changed.
Could you please tell me how to get over this?
