How to Find Half Shorting in Mobile using Digital DC Power Supply

  1. Put power to your Smartphone using DC Power Supply(As your Phone's DC power needs) Normally 3.8 volts is enough and in tablets, 4 volts some Chinese mobiles needs 4.2 volts 
  2. Connect Power Supply Red clip to Battery Connector +Vbat pin 
  3. And connect Black clip to both Battery Connector BSI and GND Do not touch any volume or power button
  4. If your Digital or Analog Power supply's Ampare Reading Scale shows any of current amount that’s mean there is a shortage in it.
    Digital Power supply shows Ampere Reading that’s mean there is a shortage in the phone
    DC Power supply Ampere Reading half shortage phone
