Charging Troubleshooting
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 D5001. The voltage should be
between 4.3V ~ 6V.
● Check B_PLUS voltage at C548. It should be 4.35V or lower.
● Check battery voltage at P5200 pin1. It should be 4.35V 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 R5205.
● Battery temperature should be between 0ºC ~ 45ºC to be fully charged. Check
thermistor voltage at test point (TP_BAT_THERM). It should be around half of
battery voltage at room temperature (25ºC).
