Why does a laptop say it’s at 6-8% charge, and then it dies, but when it’s at a higher charge, going from 60% to 59% takes a while?
In: Technology
Batteries aren’t perfect in the way they charge and discharge. Lithium batteries, like the ones in almost all portable devices, are very delicate, and require special care in order to charge and discharge properly. Your phone never fully discharges, because if a lithium battery fully discharges it will never charge again because something inside the battery changes chemically. Your phone or laptop is constantly monitoring the exact voltage of your battery, and the voltage tends to be more consistent when the battery is above 10-15%, but when it drops below that, the voltage becomes inconsistent and often dips below and above the acceptable range, causing the software to shut off your computer
