由于果断的蹭了【取消充电器】这个热点,小米11在充电问题上受到的关注度应该是超过了以往的任何一部小米手机。The content of this article mainly compares wired charging and wireless charging, and the power difference between original products and third-party products.
Due to the decisive use of the hot spot [cancel the charger], Mi 11 should have received more attention on charging issues than any previous Mi mobile phone.
Although most people chose the charger package when it was released, making the so-called cancellation of the charger more like a gimmick, but there are still idlers like me who are very concerned about the charging power of the Xiaomi Mi 11 when it is separated from the original charger; except for the wired In addition to charging, many people have chosen 55W vertical air-cooled wireless charging. There are also many doubts about this product: Can the 55W charging head that comes with Xiaomi Mi 11 make it run at full power? Does this wireless charger use Xiaomi’s proprietary fast charging protocol? Can the charger of the ordinary third-party PD charging protocol activate the maximum power of 50W?
At first, I planned to search for answers to the above questions on the Internet. But when I found out that there was not only a complete and accurate result on Aunt Zhang, but also a lot of wrong conclusions that could easily mislead users, I decided to test it myself and organize it into an article to share.
The wired charging part of wired charging has actually been posted before: I want to cancel the Mi 11 with the standard charger, and the third-party charger has less than 30W power. Create a position statement: Mi 11 is purchased at my own expense to ensure the fairness of the test. Hello, everyone. I’m zachal. The New Year’s Day holiday coincides with the release of Mi 11. In several communication groups on WeChat, everyone is discussing this “2021 Flagship Goalkeeper” in full swing. In the afternoon, I saw a few friends testing the charging power, and I also wanted to join in the fun on a whim. It doesn’t matter if it is tested, the final test result is really unexpected. Of course, in order to prevent buckling of hats, zachal| Like 50 Comments 46 Collection 7 View the details for the convenience of viewing the following and carry it over.
At first, Xiaomi Mi 11 canceled the standard charger. I unconditionally supported the news, because personally, it is indeed a drawer of charging head that can not be used (and there are many latest PD3.0 chargers). As for the future, you can choose whether you need a charger at the same price. Whether you think this is true for environmental protection or just a marketing, at least the interests of the pros and the opponents in this matter have not been lost.
However, in the reservation link after the press conference, the purple plain leather 12+256 version can’t choose the stand-alone package, so in the end I still failed to support Xiaomi’s environmental protection business as I wish, and chose the package with a charger. The idea at the time was that the charger could be sent away on Weibo or the official account, which was considered a disguised support for environmental protection.
Unexpectedly, if I want my Mi 11 to charge at full speed of 55W, then this charger may not be delivered.
Through my own test records and data from the charging head network in the figure below, on the Xiaomi Mi 10 Premium Edition, we can see that Xiaomi’s current charging protocol can support fast charging above 50W through a regular PD charger, plus This time Xiaomi 11 has the courage to promote [cancel the standard charger], so I think that this time Xiaomi 11 can also use the public PD protocol to reach a power of about 50W, rather than Xiaomi’s private protocol.
However, I found high-power chargers of different brands on hand. Most of them support PD3.0 (PPS). After charging the Xiaomi Mi 11, the result really surprised me.
Among the contestants, the newer PD3.0 chargers include Baseus GaN 65W second generation/ Baseus GaN 45W/Anker PowerPort III 65W, while Lenovo lipstick power supply 65W and Anker PowerPort 100W are both relatively backward PD2.0 The agreement is for reference only.
Probably the most detailed Xiaomi 11 charging power analysis test. Let’s first look at the performance of Xiaomi 11 using the original charger, power 46W, 9V5A high current fast charging protocol.
In fact, friends who have seen some accumulated knowledge should feel that something is wrong, because the power around 50W in the general PD protocol is achieved by handshaking 20V voltage, and 9V5A is still the low-voltage and high-current set of the magic change protocol. This proves that the 55W charger sold with the Xiaomi Mi 11 set supports a very typical Xiaomi proprietary protocol.
Probably the most detailed Xiaomi 11 charging power analysis test. The following is the Anker PowerPort III 65W, a PD charger that supports PPS. There are 5V/9V/15V/20V fixed voltage gears and a set of PPS gears in the protocol detection.
But in the actual work with Xiaomi Mi 11, this current mainstream PD charger can only have an output of 25W.
The following is the second generation of Baseus GaN 65W charger, which is still the mainstream new product on the market. It supports PD3.0, 5V/9V/12V/15V/20V fixed voltage range and a set of PPS voltage.
In the actual test, the same can only shake hands the 9V voltage range, and the power is 26W.
And those PD2.0 chargers with less power range and do not support PPS, not to mention, Lenovo lipstick power supply only has a power output of less than 18W. Of course, this is also due to the backwardness of the charger protocol. With the support of PD3.0 and PPS, the power handshaking between different chargers and terminals is more free, and the power will naturally be higher.
Probably the most detailed Xiaomi 11 charging power analysis test. I have passed the above test. I temporarily concluded that the power of about 45W can be reached when the original charger is used for Xiaomi 11. When replacing the current mainstream PD3.0 charger on the market, it can only be 27W hovered up and down.
Wireless charging The wireless charging problem is mostly concentrated on the 55W vertical air-cooled wireless charging. This is also the hardest hit area where I found wrong conclusions when Aunt Zhang checked other posts.
There are two questions about this product. First, whether the original 55W of Xiaomi Mi 11 can trigger full-speed fast charging normally; second, can third-party chargers trigger full-speed fast charging normally.
First, let’s look at the first question. In fact, this problem is relatively simple. People with a little physical knowledge know that no matter what protocol is under the premise of using 55W charger, it is impossible to support wireless charging and have 55W output at the same time, because there is inevitable power during wireless charging. loss.
Through the test, it can be seen that the original Xiaomi Mi 11’s 55W charger is basically around 17V when connected to the 55W vertical air-cooled wireless charging. 40W is the limit I can capture, and it remains around 35W most of the time. At this time, the animation of Xiaomi Mi 11 is TURBO CHARGE, not 50W MAX.
It can also be seen from the graph that the maximum power is maintained at about 30W for most of the first ten minutes. Then it slowly drops to 20W.



想要取消标配充电器的小米11,第三方充电器仅有不到30W功率创作立场声明:小米11为本人自费购买,保证测试的公平。大家好我是zachal。元旦假期恰逢小米11发售,微信几个交流群里大家对这部“2021旗舰机守门员”都讨论的热火朝天。下午看到有几个朋友在对充电功率做测试,我也心血来潮想凑凑热闹。不测不要紧,最终测试结果真的有些令人意想不到。当然为了防止扣帽子,zachal| 赞50 评论46 收藏7查看详情







参赛选手中较新的PD3.0充电器有倍思氮化镓65W二代/倍思氮化镓45W/Anker PowerPort III 65W,而联想口红电源65W和Anker PowerPort 100W均是比较落后的PD2.0协议,仅做参照。





下面出场的是Anker PowerPort III 65W,一款支持PPS的PD充电器。协议检测中分别有5V/9V/15V/20V的固定电压档位以及一组PPS档位。



在实际测试中,同样只能握手9V电压档位, 功率在26W。







通过测试可以看到,小米11原配55W充电器在连接55W立式风冷无线充时电压基本在17V上下,40W是我能抓拍到的极限,大部分时间还是维持在35W上下。此时小米11的动画为TURBO CHARGE,并非50W MAX。



比较有意思的事情出现在第三方充电器上。市面上常见的高功率PD协议充电器多为65W,我也看到了不少用户拿出自己手里的65W充电器但是依然没有出50W MAX的动画,因此得出了【只有小米原装的高功率充电头才能触发50W无线充电】的错误结论。


下图是我用前文出现过的Anker PowerPort III(65W)连接立式风冷无线充给小米11供电的功率测试。可以看到成功握手19V电压之后功率很轻松的达到了50W,而此时小米11充电动画也变为【50W MAX】。
