This overheating can occur because the IC is working harder than it should. When the MT6358VW IC malfunctions, it may struggle to manage the power flow, leading to increased resistance and heat. If you notice your device getting unusually hot, especially near the area where the IC is located, it’s a red flag. This heat can also cause other components to fail. This is a sign that the IC is likely malfunctioning.
Charging Issues
Problems with charging are another common symptom. Your device might not charge at all, charge very slowly, or intermittently. This is because the MT6358VW IC is responsible for controlling the charging process. If the IC is damaged, it might not properly regulate the charging current and voltage, resulting in charging issues. When the IC's charging circuits fail, the battery won't receive the correct charge, leading to various charging problems. This might involve slow charging, intermittent charging, or failure to charge at all. For example, if the device charges very slowly, it could mean the IC isn't delivering the right amount of power to the battery. If you notice your device has charging problems, it may indicate a damaged MT6358VW IC.
Device Shutting Down Unexpectedly
Sudden shutdowns can occur if the IC cannot manage the power properly. If the MT6358VW IC is failing, it may not be able to maintain stable power levels, leading to unexpected shutdowns. This can happen even when the battery level is still relatively high. In this scenario, the IC might not be able to regulate the voltage correctly, causing the device to lose power and shut down unexpectedly. These shutdowns can be frustrating and can indicate an internal problem with the power management.
