How to recalibrate your Samsung Note 4 battery
After more than year using the Samsung Galaxy Note 4, I have notice that the battery life seems to be deteriorating. The phone shut down at around 20% of battery level. I was thinking of buying a new battery but I remember I read somewhere on the internet that the battery can be recalibrated to restore the correct reading. That would be the first thing I should do before I decided to get a new battery.
