You can check shortage by put finger on all parts exist on pcb you'll feel something hot!
Anyway some times chinese phones shows shortage a little due to ringers so remove ringers then post result.

Yes ...agree with skybird.
this is the best way of removing shortness.
1. Connect the phone with power supply
2. Power on it
3. Let it ON for 2 minutes
4. Lay ur thumb on different components of PCB.
5. Fell which component is getting HOT.
6. Remove that component.

Check shortness should have been reduced.
