Step By Step Guide* How to Find & Slove Shorts on Mobile Phones..//

When I read some threads on GSM Forum its Funny to see some people's way of finding shorts on mobile phones. I am not going to talk about their methods. There are no different methods to find out that on Chinese Mobiles and others like Nokia,Samsung etc..

All mobile Short finding method is same.

The Very basic method to find if there any short on a mobile is using Analog Multimeter.

Put multimeter to x10
Check Battery Connector pins

simply put (+) test probe on GND pin and (-) test probe on Vbat Pin

if the multimeter pointer moves even a little there is a short.

You also can use a DC power supply for testing Short but this is better to find where or which part is really short. This way is not a good way to identify a short, because Power supply can't detect very small shorts which cause some faults on mobile. So remember the best method is using a multimeter.

Ok. How to find if a phone shot or not using DC power supply

Put power to your mobile using Power supply(As your mobile's power needs) Normally 3.8V is enough
some Chinese phones needs 4.2v

Connect Red clip to V bat pin
And connect Black clip to both BSI and GND
Do not touch any key or button


If you’re Power supply's Current panel shows any of current amount that’s mean there is a short in it.
If your Power supply Shows “0.00” on current panel it means there is No No No..any short
