Symptoms
- Phone does not boot using power button nor plugging in the charger
- Phone charges at 0.013A
- On DC Power Supply, it draws 82mA before prompt to boot
Solution
- The most likely culprit is Yangtze.
- Replace Yangtze (U3300)
- It is the "Charging IC" for this model
- After replacing, check if the 82mA current draw before prompt to boot is cleared, to confirm the issue is solved.
- In some cases, a liquid damaged ear speaker flex can cause no charging.
- Try testing with the ear speaker flex unplugged.
Please Note: The shield covering Yangtze is very tough to remove. It is recommended to add 138C low melt solder to all the solder joints around the edges, to make it a little bit easier to remove.
In the process, you may float Baseband or WTR that is under the shield. & cause baseband issues.
