Phone charging compatibility cross-section: Xiaomi performs surprisingly well, this major manufacturer is at the bottom

In recent years to say that the fastest progress of smart phones point, nothing more than the charging speed, just a few years of time each giant manufacturers will be cell phone charging time from more than two hours to twenty minutes or even about fifteen minutes, this experience only after personal experience to understand.

However, many friends around me said that since the cell phone fast charging protocol has gradually become popular, the compatibility problem of cell phone charging has gradually surfaced. In the past, just take a charger can give the phone fast charging (although only 18W to 27W), but now once the use of the original charging head is not the phone will appear "five volts an amp" situation, so much so that he now needs to bring the original charger before each trip, otherwise its charging speed is not as fast as the iPhone.

I believe that my friend is not the only one who has this problem, so I take this opportunity to give you a detailed explanation and test a wave of the mainstream brands on the market today on how well the phone is doing in terms of charging compatibility.

The main reason for the test is that Redmi said at the press conference that this phone is the best one in terms of charging protocol compatibility. I also used it for a test to see if Redmi was bragging or not.

What is a charging protocol?

Considering that many readers are still not sure how many fast charging protocols exist on the market, and do not understand what the private protocol format of cell phone manufacturers is, I would like to briefly introduce them to you first.

The first is the PD protocol, which is one of the most widely used fast charging protocols. Basically all smartphones and laptop devices support the PD fast charging protocol, which can support up to 240W charging efficiency. In general, the PD protocol charging line is Type-C interface at both ends, which is often referred to as "double C port line", but there are many cell phone manufacturers on the market will be the power supply side of the magic change into the A port to ensure that their private charging protocol will not be easily cracked.

Most foreign cell phone manufacturers are directly PD protocol as their standard charging protocol, such as iPhone, Samsung, Sony, etc. are using different power PD protocol, so charging these phones as long as you can take a higher power PD charging head, basically can provide full-blooded charging speed.

The second is Qualcomm QC fast charging protocol, a fast charging technology developed by the well-known core company Qualcomm for Snapdragon processors, known as Quick Charge. The latest QC 4.0 protocol can theoretically support up to 20V/5A (i.e. 100W) charging power, like the Honor 70 series and Mgaic 4 series are using this protocol, but most of the phones on the market using this protocol can only reach a maximum power of 28W.

Finally, the magic of each cell phone manufacturers after the private charging protocol, Xiaomi, OPPO, Vivo, Huawei basically have their own charging protocol and do not interoperate, which creates a situation where the user must use the original charging head that comes with the phone to give the phone a full-blooded charge.

Another point to note here is that most phones on the market not only support their own private charging protocols, but are often also compatible with PD protocols, PPS protocols, QC protocols, etc. Take Xiaomi 11 Ultra for example, according to the official data given by Xiaomi, it not only supports Xiaomi's own MIFC encrypted flash charging, but also is compatible with QC 4.0+, QC3.0+ and PD3.0 protocols downwards, which means that the maximum wired charging power of Xiaomi 11 Ultra is around 28W when using a non-original charging head.

Of course, these are theoretical data, how their actual performance will have to be tested in detail to learn.

Test session: Who is the king of compatibility?

Test equipment: Nubia 65W gallium nitride charging head, Bess 65W 2C1A charging head and the original charging head of each family.

In addition, it should be noted that the five phones are equipped with ATC cables, so once the need to use the ctc cable is involved in the testing process, we use a 6A high-current charging cable purchased by Xiao Lei as a substitute.

Xiaomi 11 Ultra

The first to appear is Xiaomi 11 Ultra, in the use of its own 120W charging head, its maximum power up to 57W, but this power lasts only half a minute, when the phone power more than 20% of the power quickly fell to 40W. as for the reason will not be too much here to introduce.

When the charging head is replaced with the Nubia 65W A port, it can be seen from the relevant testing instruments that the charging protocol triggered at this time is QC3.0 protocol, and the power is only 20W up and down, which is considered to be in line with the official description of Xiaomi.

After replacing the Nubia 65W power supply port with a C-port, the Xiaomi 11 Ultra triggers the PD3.0 protocol, with the same power at 27W up and down. You may feel that the PD3.0 protocol charging power is a bit lower compared to the original 67W, but this is already the highest grade of Xiaomi's non-private protocols, and Xiaomi's own private protocols are fully adopted from 33W onwards.

Next is the Bess 65W GaN charging, as the A port does not support PD3.0 protocol, so it can only provide up to about 18W of charging power when powering the Xiaomi 11 Ultra. The remaining two C ports both support PD3.0 protocol, so they can provide 27W of charging power to Xiaomi 11 Ultra.

Then the original charging head of Glory, OPPO and Vivo, in order to save space and readers' time, the detailed results will be placed directly in the table below.

As you can see from the table, the Xiaomi 11 Ultra's compatibility is quite good, basically the charging head that supports PD3.0 can provide it with about 27W charging power, although it is far from 67W, but it is better than 18W or 5W.

OPPO Find X5 Pro

The second appearance is OPPO Find X5 Pro, I was a little surprised that the official publicity of its charging power is 80W, but in the test process only 30s of time charging power exceeded 70W, after that has been stable at 50W or less. What's more interesting is that the data obtained using OPPO's 65W charging head is almost identical to that of the 80W charging head (which means that it is around 50W most of the time), so I can only say that OPPO's progress in charging in the last two years has been really slow.

In the third-party charging head test session, OPPO Find X5 Pro's performance is even more I was shocked, first Nubia 65W, the two C port can only activate QC3.0 protocol, that is, the highest power of 18W, A port performance is worse, only activated QC1.0 protocol, power is only about poor 10W. If you use the wrong charging head to charge the OPPO Find X5 Pro, the charging time is even slower than the iPhone.

The test result of BES 65W is exactly the same as Nubia, both C-port can activate QC3.0 protocol, A-port only supports about 10W power supply.

As before, the test data of OPPO Find X5 Pro when using friendly charging heads are listed below.

vivo X70 Pro+

The third person to be tested is Vivo X70 Pro+, whose power is W when using the original charging head, and the peak power can go up to 63W, but the duration is only a minute or so, after which the whole time is stable at 47W or less. Although Xiao Lei has heard friends say that Vivo's compatibility with third-party charging heads is the worst in the country, most of them can only provide a power of 10W, but the actual performance still has to be tested before a conclusion can be drawn.

The same as before, I plugged the Vivo X70 Pro+ into the three power supply ports of Nubia and Bayside in turn, and the data obtained was surprisingly consistent: both power supply ports can only stimulate the most basic QC protocol, and it seems that the Vivo X70 Pro+ also deliberately limits the current input, so that the final data is basically around 10W, and there is even a power supply port that can only provide 9W of charging power, which can be said to be quite miserable.

To sum up the two models, OPPO Find X5 Pro and Vivo X70 Pro+, their support for PD and QC, the two mainstream charging protocols, is really poor, especially the Vivo X70 Pro+, no matter how the test can only activate the bloody PD3.0 protocol. So readers holding these two phones, when choosing a charging head or try to choose the original charging head or the official store in the charging head, want to use a third-party charging head to these two phones to achieve fast charging is obviously not very realistic.

Honor Magic 4 Pro

The fourth phone is the Honor Magic 4 Pro, which is somewhat similar to the performance of the OPPO Find X5 Pro when using the original charging head, although rated at 100W fast charging, however, the actual power tested out is only 50W out, which can be said to be half cut. Even using the 66W charger of the Glory Magic 3 to the perfect version of the test data is almost the same, it seems that Glory is still too conservative in this area of charging, in order to reduce the heat of the phone charging and to limit the power, I do not know whether it is a good thing or a bad thing.

While using Nubia 65W for testing, the performance of the Honor Magic 4 Pro made me think for a moment that I had a problem with the test, no matter how to re-plug, the power was only about 2.5W. How exaggerated is this data, you will be plugged into the computer when the phone charging power is probably higher than this, I do not know if there is a problem with the test or Glory's own compatibility protocol is too crotch pulling.

The performance of the Honor Magic 4 Pro in the face of Bess and other third-party charging heads is equally disappointing, supporting only QC2.0 protocol at the highest, which really took me by surprise.

Redmi Note 11 Pro+

The last one to appear was the Redmi Note 11 Pro+, which is officially claimed to be the best phone on the market in terms of charging compatibility, but the actual performance will have to be tested to find out.

The first test was conducted using the 120W charging head that came in the box. The peak power was close to 94W and lasted for about two minutes, after which the overall power tended to stabilize at 70W or less. This charging speed is already considered to be the first tier level at this time.

However, we are most concerned about how it performs when charging with third-party charging heads. First of all, the 65W charging head of BES is capable of activating PD3.0 protocol for all three power ports, and the power is around 27W.

When replacing the charging head with Nubia's 65W A-port, the Redmi Note 11 Pro+ triggered the 5A PPS protocol as seen on the professional testing instrument, and the power went straight up to over 50W, which is very close to the performance of the original charging head.

The Redmi Note 11 Pro+ also performs quite well when charging with several other charging heads, which is indeed worthy of the bragging rights Redmi had at the launch.

To briefly summarize these five models, except for the Xiaomi model, the other three phones basically only support the older PD and QC protocols, especially Vivo, which only supports the neutered version of PD3.0 protocol, which will undoubtedly bring consumers a poor charging experience. The Redmi Note11 Pro+ is not only compatible with the mainstream PD and QC protocols, but is also capable of activating the 5A PPS protocol, so readers using this model can pay attention to whether the 5A PPS protocol is supported when buying third-party charging heads, which can also bring a good charging experience.

Summary.

After detailed testing, I was still disappointed with the results of this test. None of the phones were able to meet my expectations, even the Redmi Note 11 Pro+, which was advertised at the launch as having excellent charging compatibility, only has one more 5A PPS protocol than the Xiaomi Mi 11 Ultra, and does not support higher versions of PD and QC fast charging protocols. Although these test results may be related to the fact that the charging head I have is not complete enough, it still proves that these phone manufacturers are doing a disappointing job in charging compatibility.

As for the reason we should all understand, the profits of cell phone accessories are much higher than we think, if all cell phone manufacturers are willing to share their own charging technology or join a charging alliance, not only will greatly lose a major selling point of their own products, but also greatly reduce the profits of their own related accessories, cell phone manufacturers are not willing to cut off their own financial road.

In any case, as consumers, we still hope that these cell phone manufacturers can gradually begin to pay attention to the charging compatibility of cell phones, after all, who do not like to go out of a distance also have to bring different equipment charging equipment, both occupy space and increase the weight on the shoulder.

Of course, it is not entirely clear that these phones have no third-party charging head available, and now with the rise of many charging head brands, they have also begun to focus on the user experience, trying to get part of the private fast charging protocol. So when we buy a third-party charging head for our phones, we need to look carefully at the protocols it supports to avoid spending a lot of money and only getting a poor experience.
