Ways To Calibrate Laptop Battery in Windows 10

Many of us use laptops for hours at a stretch, every single day. With constant wear and tear, your laptop battery is bound to weaken over a period. And, one of the evident signs that your laptop’s battery has become weak is when you start to see differences in the percentage of battery your laptop is showing and the actual amount of time it lasts.
