How To Check Short Circuit in Mobile Phone

All Phone Short finding method is the same. you can use Digital, Analog Multimeter, and Digital Power Supplies both to find the shortage in smartphone motherboards. Before removing shorting you should know whether your mobile phone circuit board is short or not. Learn how to check short circuits in mobile phones.
You also can use a DC Digital power supply for testing Shortages but this is better to find where or which part of the smartphone is really short. This way is not a good way to identify a shortage because the DC Power supply can't detect very small shorts in the motherboard which cause some faults on Phones. So remember the best method is using a Digital or Analog Multimeter for mobile short checking.

Digital Multimeter

how to find a short circuit with a multimeter
  1. Set multimeter on CONTINUITY
  2. Scenario 1: Connect the Black probe to Circuit's +VE print.  and Red probe to Circuit's -VE print shows some reading.
  3. Scenario 2: Connect the Black probe to Circuit's -VE print and the Red probe to Circuit's +VE print shows no reading.

Note: IF reading shows in BOTH scenarios it means the circuit has a Shortage. That is all for how to check for a short with a multimeter.

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

  1. Put the 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 need 4.2 volts 
  2. Connect Power Supply Red clip to Battery Connector +Vbat pin 
  3. And connect the Black clip to both Battery Connectors 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 the current amounts that means 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

    Watch DC Power Supply Ampere Reading half shortage GIF here. 
5. Mobile Short Solution: if your Power supply Shows “0.00” on Ampare Reading Scale it means there is no any shortage in the motherboard

I suggest you watch the disassembling video on youtube first then remove LCD, camera, etc because we just need the motherboard, not the whole phone short circuit no disassembly.

2. Clean the entire motherboard thoroughly with any circuit cleaner like Philips contact cleaner spray, alcohol, thinner, etc. Now dry it completely. After each cleaning step, you have to check if the shortage is not gone and proceed to the next step.

3. Now try to deep clean the Phone Circuit Board. There is a liquid called Elma used by smartphone repair technicians in Eastern Europe countries named Elma
