Troubleshoot Xtool X100 Pad2 battery drains too fast

Xtool X100 Pad2 battery issue not always happens, but if it does, for example “It works a littl time and the battery says XX% and later powered off and not start.” Then please fix it by following mainly three steps:

 

Step 1: Disassemble the C6 capacitor and desolder a 4.7K 0603 resistor. (see details below)

Step 2:  Disassemble the Q14 transistor (see details below)

Step 3: Replace the C123 capacitor witth a 3.3K%5 0402 resistor. (see details below)

 

Two pieces of tools to prepare:

Tool Jig:

Static bracelet (Number: 1)

Hot air gun (Number: 1), Temperature: 350±10℃
