In recent years, the fastest point of smart phone progress is the charging speed, in just a few years, the giant manufacturers have reduced the charging time of mobile phones from more than two hours to twenty minutes or even fifteen minutes, this experience can only be understood after personal experience.
But many friends around me said that since the gradual popularization of mobile phone fast charging protocols, the compatibility problem of mobile phone charging has gradually emerged. In the past, a charger could be used to quickly charge the phone (although it was only 18W to 27W), but now once the original charging head of the mobile phone is not used, there will be a "five volt and one amp" situation, so that he now needs to bring the original charger of the mobile phone every time he goes out, otherwise its charging speed is not as good as the iPhone.
I believe that not only my friend has this problem, so I will take this opportunity to explain to you in detail today and test how well a wave of mainstream brand mobile phones on the market today are doing in charging compatibility.

The models participating in the test are: OPPO Find X5 Pro, Xiaomi 11 Ultra, vivo X70 Pro+, Redmi Note 11, Honor Magic 4 Pro. As for why a newly released mid-range machine was specially crammed into the four flagship phones, mainly at the press conference, Redmi said that this phone is the best charging protocol compatibility at present, so I also took it to do a test to see if Redmi is bragging about this time.
What is a charging protocol?
Considering that many readers are not clear about how many fast charging protocols exist on the market at present, nor do they understand what the private protocol format of mobile phone manufacturers is, I will briefly introduce it to you first.
The first is the PD protocol, PD protocol is currently one of the most widely used fast charging protocols, basically all smart phones and notebook devices support PD fast charging protocol, which can support up to 240W charging efficiency. Under normal circumstances, both ends of the PD protocol charging line use the Type-C interface, which is what we often call the "double C port line", but at present, there are many mobile phone manufacturers on the market that change the power supply end to the A port to ensure that their private charging protocol will not be easily cracked.
Most foreign mobile phone manufacturers are directly using the PD protocol as their own standard charging protocol, such as iPhone, Samsung, Sony, etc. have adopted PD protocols with different powers, so as long as they can take a higher power PD charging head when charging these mobile phones, they can basically provide full blood charging speed.
Followed by Qualcomm QC fast charging protocol, is the well-known chip company Qualcomm to equip the Snapdragon processor developed fast charging technology, the full name of Quick Charge, Qualcomm QC fast charging has released four generations of standards, respectively, QC1.0, QC2.0, QC3.0, QC4.0. Among them, the latest QC 4.0 charging protocol can theoretically support up to 20V/5A (that is, 100W) charging power, like the Honor 70 series and Mgaic 4 series are used in this protocol, but most of the mobile phones using this protocol on the market can only reach a maximum power of 28W.

Finally, the private charging protocols after the magic modification of mobile phone manufacturers, Xiaomi, OPPO, vivo, and Huawei basically have their own charging protocols and do not communicate with each other, which also creates a situation where users must use the original charging head of the mobile phone to charge the mobile phone with full blood.
Here is another point to explain, most of the mobile phones on the market not only support their own private charging protocols, but also often compatible with PD protocols, PPS protocols, QC protocols and so on. Take Xiaomi 11 Ultra as an example, according to the data given by Xiaomi officially, it not only supports Xiaomi's own MIFC encrypted flash charge, but also can be compatible with QC 4.0+, QC3.0+ and PD3.0 protocols, that is to say, in the case of using non-original charging heads, the highest wired charging power of Xiaomi 11 Ultra is around 28W.
Of course, these are theoretical data, and their actual performance will have to be tested in detail to know.
Test session: Who is the king of compatibility?
Test equipment: Nubia 65W Gallium Nitride charging head, Beth 65W 2C1A charging head and the original charging head of each home;

In addition, it is also necessary to state that since the five mobile phones are equipped with ATC cables, once it comes to the use of CTC cables during the test process, they all use a 6A high-current charging line purchased by Xiaolei as a substitute.
Xiaomi Mi 11 Ultra
The first to appear is the Xiaomi Mi 11 Ultra, when using its own 120W charging head, its maximum power can reach 57W, but this power duration is only half a minute, when the phone power exceeds 20% after the power quickly fell to 40W. As for the reasons, I will not go into too much here.
When the charging head is replaced with the A port of Nubia 65W, it can be seen from the relevant detection instruments that the charging protocol triggered at this time is the QC3.0 protocol, and the power is only about 20W, which is also in line with xiaomi's official description.

After replacing the Nubia 65W power supply port with a C port, the Xiaomi Mi 11 Ultra triggered the PD3.0 protocol, and the power was also around 27W. You may think that the charging power of the PD3.0 protocol is lower than the original 67W, but this is already the highest grade in Xiaomi's non-private protocol, and Xiaomi's own proprietary protocol has been fully adopted since 33W.
Then there is the Beth 65W Gallium Nitride charging, because the A port does not support the PD3.0 protocol, so it can only provide a maximum of about 18W of charging power when powering the Xiaomi Mi 11 Ultra. The other two C ports support the PD3.0 protocol, so they can provide 27W charging for the Xiaomi Mi 11 Ultra.
Then there are the original charging heads of Honor, OPPO and Vivo, in order to save space and time for readers, the detailed results are placed directly in the table below.

As can be seen from the table, the compatibility of Xiaomi 11 Ultra is not bad, basically supporting the PD3.0 charging head can provide it with about 27W charging power, although it is far from 67W, but it is better than 18W and 5W.
OPPO Find X5 Pro
The second person to appear is the OPPO Find X5 Pro, which surprises me a little bit that the official advertised charging power is 80W, but the charging power exceeded 70W in only 30s of time during the testing process, and has been stable at around 50W ever since. What is more interesting is that the data obtained by using OPPO's 65W charging head is almost the same as that of the 80W charging head (referring to the fact that most of the time it is about 50W), and it can only be said that OPPO's progress in charging in the past two years is really slow.

In the test link of the third-party charging head, the performance of oppo Find X5 Pro is even more surprising to me, first of all, Nubia 65W, the two C ports can only activate the QC3.0 protocol, that is, the maximum power is 18W, and the performance of the A port is even worse, only activating the QC1.0 protocol, and the power is only about 10W. If you use the wrong charging head to charge the OPPO Find X5 Pro, the charging time is even much slower than that of the iPhone.
The test results of beth 65W are exactly the same as nubia, both C ports can activate the QC3.0 protocol, and the A port only supports about 10W power supply.
As in the previous article, the test data of OPPO Find X5 Pro when using the Friendly Charging Head is as follows:

vivo X70 Pro+
The third person to be tested is vivo X70 Pro+, which has a power of W when using the original charging head, and the peak power can go up to 63W, but the duration is only more than one minute, and then it is stable at around 47W. Although Xiao Lei has heard friends say before that vivo's compatibility with third-party charging heads is the worst batch in China, most of them can only provide power in the early 10W, but the actual performance still has to be tested before the conclusion can be determined.

As in the previous article, I inserted the vivo X70 Pro+ into the three power supply ports of Nubia and Beth in turn, and the data obtained was amazingly consistent: no matter which power supply port can only stimulate the most basic QC protocol, and vivo X70 Pro+ seems to deliberately limit the current input, so that the final data is basically around 10W, and even a power supply port can only provide 9W charging power, which can be said to be quite tragic.

To summarize the OPPO Find X5 Pro and vivo X70 Pro+ models, their support for PD and QC, the two mainstream charging protocols, is indeed poor, especially vivo X70 Pro+, no matter how tested can only activate the residual blood PD3.0 protocol. Therefore, readers who hold these two mobile phones, when choosing a charging head, still try to choose the original charging head or the charging head in the official store, and it is obviously unrealistic to use a third-party charging head to achieve fast charging for these two mobile phones.
Honor Magic 4 Pro
The fourth mobile phone is the Honor Magic 4 Pro, which uses the original charging head when the performance is somewhat similar to the OPPO Find X5 Pro, although the rated is 100W fast charging, but the actual tested power is only more than 50W, which can be said to be halved. Even if the data tested using the Honor Magic 3 to the best version of the 66W charger is almost the same, it seems that honor is still too conservative in charging, in order to reduce the heat generated when the phone is charged and limit the power, I don't know whether it is a good thing or a bad thing.

When testing with the Nubia 65W, the performance of the Honor Magic 4 Pro made me think that there was a problem with my test, and no matter how it was reseated, the power was only about 2.5W. How exaggerated is this data, the charging power when you plug the phone into the computer is probably higher than this, I don't know if there is a problem with the test or honor's own compatible 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 also disappointing, and the maximum can only support the QC 2.0 protocol, which really surprised me.
Redmi Note 11 Pro+
The last to appear is the Redmi Note 11 Pro+, which officially claims to be the best charging compatibility phone on the market, but the actual performance of the actual performance has to be tested before it can be known.
First of all, the 120W charging head included in the box was used for testing, and its peak power can be close to about 94W and last for two minutes, and then the overall trend tends to stabilize at around 70W. This charging speed is already the first echelon level at the moment.

However, what we are most concerned about is how it performs when charging with a third-party charging head, first of all, the Beth 65W charging head, three power supply ports can activate the PD3.0 protocol, the power is around 27W, just when I think Redmi is a bit exaggerated when I found a new continent.
When the charging head is replaced with a 65W A port in Nubia, it can be seen from the professional test instrument that the Redmi Note 11 Pro+ triggered the 5A PPS protocol, and the power directly rose to more than 50W, which is very close to the performance of the original charging head.

The Redmi Note 11 Pro+ also performs well when charging with several other charging heads, and it is indeed worthy of the bull that Redmi bragged about at the conference.
To briefly summarize these five models, in addition to the Xiaomi model, the other three mobile phones basically only support the older PD and QC protocols, especially vivo even only supports the castrated version of the PD3.0 protocol, which will undoubtedly bring consumers a poor charging experience. In addition to being compatible with the mainstream PD and QC protocols, the Redmi Note11 Pro+ can also activate the 5A PPS protocol, so readers who use this model can pay attention to whether they support the 5A PPS protocol when purchasing third-party charging heads, which can also bring a good charging experience.
Summary:
After detailed testing, I am still disappointed with the results of this test, no mobile phone can meet my expectations, even the conference to promote the highly compatible Redmi Note 11 Pro+ is only one more than the Xiaomi 11 Ultra 5A PPS protocol, and does not support higher versions of PD and QC fast charging protocol. Although these test results may have something to do with the incomplete protocols supported by the charging head in my hand, in the final analysis, it still proves that these mobile phone manufacturers have done a disappointing job in terms of charging compatibility.
As for the reason, everyone should have some understanding, the profit of mobile phone accessories is far higher than we imagined, if all mobile 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 profit of their own related accessories, mobile phone manufacturers are not willing to cut off their own financial road.
In any case, as consumers, we still hope that these mobile phone manufacturers can gradually begin to pay attention to the charging compatibility of mobile phones, after all, no one likes to go out of the door and have to bring charging equipment with different devices, which not only occupies space but also increases the weight on the shoulders.
Of course, it is not completely indicated that these mobile phones do not have third-party charging heads available, and now with the rise of many charging head brands, they have also begun to pay attention to the user's experience, and try to win part of the private fast charging protocol. Therefore, when we choose a third-party charging head for a mobile phone, we need to carefully look at the protocol it supports, so as not to spend a lot of money but only get a poor experience.
