switch everything off . switch off youe data , wifi , bluetooth ( if you are using ) and all other processes which consume battery and/or data like gps etc . after that , clear and terminate every process .. clear your recents app and then connect the charger .. leave it untouched for an hour or two ( depends upon your mobile and how much you want it to be charged ) and then you'll see the phone charges well .... make sure you are not using the phone while charging .. follow the steps i have asked yo to and switch brightness to 0 .. hope i helped .. all the best
