Gather Supplies:

Wire Connection:

  • After removing the phone battery, connect and tape one wire to the positive end of the 9-volt battery.
  • Connect and tape the other wire to the negative end of the 9-volt battery.

Connect to Phone Battery:

  • Identify the positive and negative sockets on your mobile battery for repair.
  • Connect the positive wire to the positive end and the negative wire to the negative end of the phone battery.
  • Keep the connection on for 10 to 60 seconds, monitoring every 10 seconds to avoid overheating.

Now remove all the connections once it gets a little warm, and insert it back to your mobile phone and check. This should give you a little charge in the battery.
