:confused::confused::confused: All Mobile Low Battery Backup Problem- How To Check & Isolate??? :confused::confused::confused:
All Mobile Low Battery Backup. How to check that fault is in PCB or Battery+Charger etc??????????
BR Insert Simcard Then Fully Turn On The Phone With DC Power Supply 3.7-4V
Wait Untill BackLight Off, Then Wait Approx 2-5 minutes...
If The mA Meter Needle Decrease 0mA Means Phone Should Be Ok, If Needle Continue Show Kicking Or Pulse Means PCB related fault. So Check Power Consumption Section. Best Of Luck
