Sony Ericsson Xperia Arc LT15i Usb Charging Ways

Reasons of Problems

• Might be the problem in charger or charger’s pin.
• It also happens due to the dust present in charging connector of your phone.
• Dry soldering of charging pins, you need to re-solder them again. However for that you need to remove metal sheet over charging pins with the help of a heat gun in order to access charging pins for soldering.
• Might be due to uneven voltage. It happens due to faulty circuit.
• Fuse or Capacitor might also be faulty.

• The very first thing that you need to do is to check voltage at the testing point 1 (as mentioned above in Figure). The voltage should be around 4.9V to 5V. other testing points are for USB connector.
• In case there is no or uneven voltage at the charging point, then remove metal shield off from charging connector and re-solder all the pins of charging connector.
• If still there is no or uneven voltage then place jumper at the testing point.

• Afterwards Check fuse, if it is faulty then replace it or place a jumper instead. A jumper will work similarly as of a fuse.
• Now check capacitor, replace if it is faulty.
• Now follow the following steps in order to resolve Charging IC issue:
• Gently heat charging IC and check.
• If the above step fails then remove and re-fix IC.
• If it is still found to be faulty then replace it.

All of the above methods will surely help you in resolving
