Charging IC for Lenovo Tab 4 10 Plus 16GB WiFi

The Charging IC in your Lenovo Tab 4 10 Plus 16Gb Wifi is the chip responsible for managing all aspects of battery charging — regulating the input voltage and current from the charger, controlling fast charging protocol negotiation, protecting the battery from overcharge and overheating, and communicating battery status to the system. A faulty Charging IC causes charging to fail completely, run abnormally slowly, or stop at a fixed percentage on your Lenovo Tab 4 10 Plus 16Gb Wifi.

If the charging port is physically intact, the cable and adapter work on other devices, and the battery is confirmed healthy — but charging still fails, overheats, or cuts off — the Charging IC on your Lenovo Tab 4 10 Plus 16Gb Wifi motherboard is the likely fault. Partial failure often presents as fast charging stopping while slow charging still works. A board-level technician can confirm with multimeter testing.

Yes. A malfunctioning Charging IC can fail to regulate input voltage correctly — sending excess current or voltage into the battery of your Lenovo Tab 4 10 Plus 16Gb Wifi. This causes accelerated battery degradation, abnormal heating during charging, and in severe cases battery swelling. If your Lenovo Tab 4 10 Plus 16Gb Wifi gets very hot during charging and the battery is swelling, stop charging immediately and have both the Charging IC and battery inspected by a professional.

No. The Charging IC is a micro-SMD chip soldered onto the Lenovo Tab 4 10 Plus 16Gb Wifi motherboard. It requires hot air rework equipment, flux, and professional board-level skills to replace safely. Incorrect installation can short the charging circuit and cause irreparable motherboard damage.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
