The fastest progress in smartphones in recent years is the charging speed. In just a few years, major manufacturers have reduced the charging time of mobile phones from more than one or two hours to twenty minutes or even ten minutes. For about five minutes, it’s an experience that can only be understood once you experience it.
But many friends around me said that since the mobile phone fast charging protocol gradually became popular, the compatibility issue of mobile phone charging has gradually emerged. In the past, he could quickly charge his mobile phone with any charger (although it was only 18W to 27W), but now if he uses a charger other than the original one of his mobile phone, the "five volts and one ampere" situation will occur, so that he now has to charge the phone before going out every time. You need to bring the original charger of your mobile phone, otherwise its charging speed will not be as fast as that of iPhone.
I believe that my friend is not the only one who has this problem, so I will take this opportunity to explain and test the charging compatibility of a wave of mainstream brand mobile phones on the market today.

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 just-released mid-range phone was specifically included among the four flagship phones, it was mainly because at the press conference Redmi said that this phone has the best charging protocol compatibility at present, so I also specially used it. Do a test to see if Redmi is bragging this time.
What is the charging protocol?
Considering that many readers do not know how many fast charging protocols currently exist on the market, nor do they understand what the private protocol formats of mobile phone manufacturers are, I will briefly introduce them to you first.
The first is the PD protocol. The PD protocol is one of the most widely used fast charging protocols. Basically all smartphones and notebook devices support the PD fast charging protocol, which can support a maximum charging efficiency of 240W. Generally, both ends of the PD protocol charging cable use Type-C interface, which is what we often call "double C port cable". However, there are also many mobile phone manufacturers on the market that change the power supply end to A port. situation to ensure that their private charging protocols cannot be easily cracked.
Most foreign mobile phone manufacturers directly use the PD protocol as their standard charging protocol. For example, iPhone, Samsung , Sony , etc. all use PD protocols with different powers. Therefore, when charging these mobile phones, as long as they can A PD charging head with higher power can basically provide full charging speed.
followed by Qualcomm QC fast charging protocol, which is a fast charging technology developed by the well-known chip company Qualcomm for Snapdragon processors. Its full name is Quick Charge. Qualcomm QC fast charging has currently released four generations of standards, respectively. For QC1.0, QC2.0, QC3.0, QC4.0. Among them, the latest QC 4.0 charging protocol can theoretically support up to 20V/5A (i.e. 100W) charging power. This protocol is used by Honor 70 series and Mgaic 4 series, but most mobile phones using this protocol on the market have the highest power. It can only reach 28W.

Finally, there are private charging protocols modified by various mobile phone manufacturers. Xiaomi , OPPO , vivo, Huawei basically have their own charging protocols and are not interoperable, which means that users must use mobile phones. Only the original charging head that comes with it can fully charge the phone.
There is another point to note here. Most mobile phones on the market not only support their own private charging protocols, but are also often compatible with PD protocols, PPS protocols, QC protocols, etc. Take Xiaomi 11 Ultra as an example. According to Xiaomi’s official data, it not only supports Xiaomi’s own MIFC encrypted flash charging, but is also backward compatible with QC 4.0+, QC3.0+ and PD3.0 protocols. In other words, when using a non-original charging head, the maximum wired charging power of Xiaomi Mi 11 Ultra is around 28W.
Of course, these are theoretical data, and their actual performance will only be known after detailed testing.
test session: Who is the king of compatibility?
test equipment: Nubia 65W gallium nitride charging head, Baseus 65W 2C1A charging head and each manufacturer’s original charging head;

In addition, it needs to be stated that since the five mobile phones are equipped with ATC wires from the factory, once it is involved during the test process, ctc needs to be used When it comes to wires, a 6A high-current charging wire purchased by Xiaolei is used as a substitute.
Xiaomi 11 Ultra
The first one to appear is Xiaomi 11 Ultra. When using its own 120W charging head, its maximum power can reach 57W, but this power lasts only half a minute. When the phone’s power exceeds 20%, the power will drop rapidly. dropped to 40W. I won’t go into too much detail here about the reasons. When
replaced the charging head with the Nubia 65W A port, it can be seen from the relevant testing instruments that the charging protocol triggered at this time is the QC3.0 protocol, and the power is only about 20W, which is in line with Xiaomi's official description.

After replacing the Nubia 65W power supply port with the C port, the Xiaomi Mi 11 Ultra triggers the PD3.0 protocol, and the power is 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 level among Xiaomi's non-proprietary protocols. Starting from 33W, Xiaomi's own private protocol has been fully adopted.
Next is Baseus 65W gallium nitride charging. Since the A port does not support the PD3.0 protocol, it can only provide a maximum charging power of about 18W when powering Xiaomi 11 Ultra. The remaining two C ports support the PD3.0 protocol, so they can provide 27W charging for Xiaomi 11 Ultra.
Then there are the original charging heads of Honor, OPPO and vivo. In order to save space and readers’ time, the detailed results are placed directly in the table below.

As you can see from the table, the compatibility of Xiaomi Mi 11 Ultra is pretty good. Basically, a charging head that supports PD3.0 can provide it with a charging power of about 27W, although it is different from 67W. Far, but still much better than 18W or 5W.
OPPO Find X5 Pro
The second entry is OPPO Find X5 Pro. What surprised me a little is that the official promotion of its charging power is 80W, but during the test, the charging power exceeded 70W for only 30 seconds, and it has been stable since then. Around 50W. What’s 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 (meaning that it is around 50W most of the time). It can only be said that OPPO’s progress in charging in the past two years is indeed a bit slow.

In the test session of the third-party charging head, the performance of OPPO Find X5 Pro surprised me. Let’s talk about Nubia 65W first. The two C ports can only activate QC3. 0 protocol, that is, the maximum power is 18W. The performance of port A is even worse. Only the QC1.0 protocol is activated, and the power is only about 10W. If you use the wrong charging head to charge OPPO Find X5 Pro, the charging time will even be much slower than that of the iPhone. The test results of
Baseus 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.
Same as the previous article, the test data of OPPO Find X5 Pro when using a friendly charging head are as follows:

vivo X70 Pro+
The third person to undergo the test is vivo X70 Pro+, using the original charger When the head is turned on, its power is W, the peak power can reach up to 63W, but the duration is only a little over a minute, and then the whole process stabilizes at around 47W. Although Xiaolei has heard from friends before that vivo’s compatibility with third-party charging heads is among the worst in China. Most of them can only provide a power of just over 10W, but the actual performance still needs to be tested after actual testing. Draw conclusions.

As before, I plugged the vivo X70 Pro+ into the three power supply ports of Nubia and Baseus in sequence, and the data obtained are surprisingly consistent: No matter which power supply port is used, only Can stimulate the most basic QC protocol, and vivo X70 Pro+ seems to have deliberately limited the current input, so that the final data is basically around 10W. There is even a power supply port that can only provide 9W charging power, which can be said to be quite miserable.

To summarize the two models of OPPO Find X5 Pro and vivo X70 Pro+, their support for the two mainstream charging protocols of PD and QC is indeed relatively poor, especially the vivo X70 Pro+, regardless of No matter how I test, I can only activate the PD3.0 protocol with residual blood. Therefore, readers holding these two mobile phones should try to choose the original charging head or the charging head from the official mall when choosing a charging head. It is obviously unrealistic to use a third-party charging head to achieve fast charging for these two mobile phones. of.
Honor Magic 4 Pro
The fourth mobile phone is Honor Magic 4 Pro. Its performance when using the original charging head is somewhat similar to OPPO Find X5 Pro. Although it is rated for 100W fast charging, the actual tested power is only over 50W. It can be said that It was cut in half. Even using the 66W charger of the Honor Magic 3 Ultimate Edition, the test data is almost the same. It seems that Honor is still too conservative in charging. It limits the power in order to reduce the heat generated when charging the phone. I don’t know what the reason is. Good thing or bad thing.

When testing with Nubia 65W, the performance of Honor Magic 4 Pro made me think that there was something wrong with my test. No matter how I unplugged and plugged it in again, the power was only about 2.5W. How exaggerated is this data? The charging power when you plug your phone into a computer is probably higher than this. I don’t know if there is a problem in the test or if Honor’s own compatibility protocol is too stretched.
The performance of Honor Magic 4 Pro in the face of Baseus and other third-party charging heads is also disappointing. It can only support the QC2.0 protocol at best, which really surprised me.
Redmi Note 11 Pro+
The last one to appear is the Redmi Note 11 Pro+. The official claims that this is the mobile phone with the best charging compatibility on the market, but the actual performance will not be known until testing.
first used the 120W charging head that comes in the box for testing. Its peak power can be close to about 94W and can last for two minutes. After that, the overall power tends to stabilize around 70W. This charging speed can be regarded as the first-tier level at the moment.

However, what we are most concerned about is how it performs when charging with a third-party charging head. The first is the Baseus 65W charging head. All three power supply ports can activate the PD3.0 protocol, and the power They are all around 27W. Just when I thought Redmi was exaggerating, I discovered a new world.
When replacing the charging head with Nubia's 65W A port, it can be seen from professional testing instruments that the Redmi Note 11 Pro+ triggered the 5A PPS protocol, and the power rose directly to more than 50W, which is very close to the performance of the original charging head. .

Redmi Note 11 Pro+ performs quite well when charged with several other charging heads, and it is indeed worthy of Redmi’s bragging at the press conference.
Let’s briefly summarize these five models. Except for the Xiaomi model, the other three mobile phones basically only support the older PD and QC protocols. In particular, vivo only supports the castrated version of the PD3.0 protocol. This is undoubtedly It will bring poor charging experience to consumers. In addition to being compatible with mainstream PD and QC protocols, Redmi Note11 Pro+ can also activate the 5A PPS protocol. Therefore, readers using this model can pay attention to whether it supports the 5A PPS protocol when purchasing a third-party charging head. It can also activate the 5A PPS protocol. Brings a good charging experience.
Summary:
After detailed testing, I am still quite disappointed with the results of this test. No mobile phone can meet my expectations. Even the Redmi Note 11 Pro+, which was promoted at the press conference as having extremely strong charging compatibility, is only It has one more 5A PPS protocol than Xiaomi Mi 11 Ultra, and does not support higher versions of PD and QC fast charging protocols. Although these test results may have something to do with the fact that the charging head in my hand does not support a complete set of protocols, in the final analysis it proves that these mobile phone manufacturers are relatively disappointing in terms of charging compatibility.
Everyone should know the reason. The profit of mobile phone accessories is much higher than we imagined. If all mobile phone manufacturers are willing to share their own charging technology or join a charging alliance, they will not only lose a lot of their own products. Selling points, and it will also greatly reduce the profits of related accessories. Mobile phone manufacturers are not willing to cut off their own financial resources.
No matter what, as consumers, we still hope that these mobile phone manufacturers can gradually start to pay attention to the charging compatibility of mobile phones. After all, no one likes to travel far away and have to carry charging equipment for different devices, which not only takes up space but also increases the burden. weight on.
Of course, this does not completely mean that these mobile phones do not have third-party charging heads available. Now with the rise of many charging head brands, they have also begun to pay attention to the user experience and try their best to win some private fast charging protocols. Therefore, when we buy a third-party charging head for our mobile phone, we need to carefully look at the protocols it supports, so as not to spend a lot of money only to get a poor experience.
