USB Type-C is a mixture of multiple standards. Exploring its behavior [smartphone version]

Charging connectors for smartphones and tablets are gradually shifting from Micro to Type-C, and charging cables and other commercially available accessories are becoming a lineup that reflects this. . This time, let's first use the USB cable with Type-C connectors on both ends that we used last time to power the smartphone, and explore the differences in speed and characteristics for each power supply method.

The smartphones used are SIM-free Android smartphones equipped with Type-C connectors, Huawei's "HUAWEI nova" and Trinity's "NuAns NEO [Reloaded]". The former claims to support fast charging, but it is only "5V/2A", and "9V/2A" like the company's P10 lite, or "5V/4.5A" or "4.5V/5A" of Mate 9. It is not a special specification like It is not compatible with USB PD (USB Power Delivery) introduced last time.

The latter supports Qualcomm's quick charging standard "Quick Charge 3.0", but Quick Charge is a standard that can be quickly charged only when both the power adapter side and the device side are compatible, and the power adapter used this time is None of them are compatible with Quick Charge, so you can not receive the benefits. It doesn't support USB PD either.

The power adapter uses the MacBook Pro 15-inch standard "87W USB-C power adapter" that was used last time and Anker's "PowerPort+ 5 USB-C USB Power Delivery" (maximum 30W). Both products are compatible with USB PD, but since the smartphone side does not support this time, high-speed charging unique to USB PD cannot be performed.

"HUAWEI nova". Released in February 2017. The version of Android at the time of this writing is equipped with a 7.0 Type-C connector. Trinity "NuAns NEO [Reloaded]" that comes with a cable and a dedicated adapter for the product. Released in June 2017. The version of Android at the time of writing this article is equipped with a 7.1.1 Type-C connector. Product comes with cable only, no adapter

The cables are as shown in the table below, which is the same lineup as last time. Abbreviations such as [AB], [AK], and [E1] are used in the text. In the measurement, it is difficult to match the remaining battery capacity of smartphones, so the test is performed in the range of 20-80% remaining battery capacity, which is considered to be relatively stable in charging speed.

Let's start with the HUAWEI nova. Since the voltage fluctuates between 4.7 and 5.0 V for any cable, only the current (A) value for each cable is listed below.

As you can see from the table above, HUAWEI nova was able to supply power without any problems when combined with either the MacBook adapter or the Anker adapter. . Basically, power is supplied with an upper limit of "5V x 2A", and there is a tendency for slightly more power to be supplied when using a MacBook adapter. Originally, if it does not support USB PD, the upper limit is "5V x 3A" stipulated by the USB Type-C Current standard, but since HUAWEI nova itself only supports up to 5V x 2A, it is thought that it has hit a ceiling. .

Looking at each cable, the three products [AK], [E5], and [M] that support 3A with USB 2.0 are 0.1 to 0.2A lower than the others, and the voltage is also 4.9 to 5.0. It is 4.7 to 4.9V, which is slightly lower than V. Compared to USB 3.1 compatible products, the time to complete charging is not at a level where it changes significantly, but the trend is clearly different.

In most combinations, power is supplied at a value close to "5V x 2A". This is an example of [E1] USB 2.0 3A cable has slightly lower voltage and current than others. This is an example of [AK] By the way, if you use the USB-C cable that comes with the MacBook, the value is almost the same as the group with the higher voltage current, that is, [AB], [C], [E1], etc.

Next, let's take a look at NuAns NEO [Reloaded]. Again, with the upper limit of "5V x 2A", any cable can be charged without problems. Compared to HUAWEI nova, there is almost no difference between adapters and cables, and all cables, including [AK], [E5], and [M], which were slightly lower in current and voltage in HUAWEI nova, are 1.7 ~ It is within the range of 1.9A.

As with HUAWEI nova, power is supplied at a value close to "5V x 2A". This is an example of [E1] HUAWEI nova, which showed a slightly lower value with a USB 2.0 3A compatible cable, but here shows a value that is almost the same as others. This is the same as the USB-C cable attached to the [AK] example MacBook

Overall, there is no extreme difference compared to using a conventional USB cable. If it supports USB PD, the story will change again, but if it doesn't, you can just use it the same way as the conventional USB, just with a different shape of the connector.
