Huawei Mate30 Battery Failure repair
Machine model: Huawei Mate30
Fault: Power consumption is too fast and the battery is not durable.
Maintenance process:
I received the 5G Huawei Mate30 fault machine from the customer, the fault short-circuit current, the test function is normal, and the startup current is normal. After startup, the machine will have the imagination of high temperature. After measuring the boost circuit diode value is a bit low, it must be that there is something wrong with the chip on Related circuit, and the fault can be solved after the RF multifunctional chip high temperature is replaced.
