redmi Note 8 Pro: Teardown confirms Quick Charge 3.0 support

The Redmi Note 8 Pro was at an event in China next to the Redmi yesterday Note 8, the RedmiBook notebook and the 70-inch 4K Redmi TV. Most of the specs of the device were already confirmed in advance – including the MediaTek G90T SoC. An official teardown of the device showed surprising details.

So Redmi explained that that redmi Note 8 Pro would not only support MediaTek's Pump Express quick-charge solution, but also Qualcomm's Quick Charge 3.0, Quick Charge 4+ and USB Power Delivery. In addition, Redmi has released numerous pictures of a device teardown confirming support for Qualcomm's Quick Charge 3.0.

As XDA Developers reports, one of the presentation slides at the opening event showed that the Pro version of the new phone supports multiple charging protocols and is compatible with several major chargers. In Redmi Note 8 Pro includes the new SoC MediaTek Helio G90T, so support for MediaTek's so-called "Pump Express" charging technology is mandatory, and Pump Express 4.0 is also said to be compatible with USB Power Delivery 3.0, as explained on the presentation slide.


Support for Qualcomm's Quick Charge

Surprising was the mention of Qualcomm's proprietary fast charging solutions in the form of Quick Charge 3.0 and Quick Charge 4+. However, this would mean that the phone would need additional hardware to support these solutions. Then there was the Redmi teardown shown by Redmi Note 8 per digestion.

The picture above shows the Qualcomm SMB1351 – a Quick Charge 3.0 chip (marked in light blue). This means that the Redmi Note 8 Pro contains the necessary hardware to allow this standard at least despite the difference in the SoC. However, neither this nor the other images show any hardware components that would prove support for Quick Charge 4+. In fact, to support this new technology, the phone should be equipped with either the Qualcomm SMB1380 or the SMB1381 Power Management IC. We can not explain this discrepancy at the present time, but we hope that Xiaomi will provide information even here.

Scroll through the picture gallery. It does not happen so often that manufacturers themselves allow such deep insights into their device or even publish themselves. In the photos, many components of the smartphone are color-coded and provided with explanations and can be seen accordingly well – such as the heatpipes or the microSD card slot.
