CHARGING TROUBLESHOOTING (cont'd)
In the event of charging issues :
• Do visual inspection on USB connector and battery connector.
• Check charging voltages along the charging path.
• Measure USB_PWR charger input voltage at C541 (SMB1351 Input) and
C2518 (PMI8994 input). The voltage should be between 4.3V ~ 9.90V.
• Check B_PLUS voltage at C2510. It should be 4.35V or lower.
• Check battery voltage at J510 pin 4. It should be 4.40V or lower. If battery is
below 2.1V, there maybe a short in the circuit somewhere and the battery
protection circuit is triggered.
• Check battery ground path - J510 pin 1.
• Battery temperature should be between 0ºC ~ 45ºC to be fully charged. Read the
phone temperature using the following steps: Attach a USB cable to a powered on
phone. In a terminal window, type "adb root", "adb shell", "cat /sys/class/
power_supply/battery/temp".
• The temperature will be returned with 3 digits, with no decimal so 25C will read
250.
