本文内容主要对比有线充电和无线充电,以及原装产品和第三方产品的功率差异。

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.

虽然发售之时大部分人都选择了充电器套装而使所谓的取消充电器更像是一个噱头,但仍有如我这样的闲人十分关注小米11在脱离原装充电器时的充电功率;而除了有线充电之外,也有很多人选择了55W立式风冷无线充,对于这款产品的存疑点同样很多:小米11配套的55W充电头可以使无线充满功率运行吗?这款无线充所采用的是否是小米的私有快充协议?普通第三方PD充电协议的充电器可以激活50W的最高功率吗?

上述问题起初我打算在网络上搜寻到答案。但是当我发现张大妈上不仅没有一份完善的、准确的结果,甚至还出现了不少容易误导用户的错误结论,随之我决定自己进行测试,同时整理成一篇文章来分享。
有线充电

有线充电部分其实之前已经发文说过:
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

为方便观看下面搬运过来。

起初小米11取消标配充电器听到这条消息我是无条件支持的,因为就我个人来说,确实是一抽屉的充电头用不过来(而且有不少最新的PD3.0充电器)。至于之后同售价可自行选择是否需要充电器,无论你觉得这是真真切切为了环保还是只是一场营销,至少无论是赞成者还是反对者在这件事情上的利益都没有受到损失。

然而在发布会之后的预定环节,紫色素皮12+256的版本始终不能选择单机套餐,所以最后我还是没能如愿支持小米的环保事业,选择了带充电器的套装。当时的想法是可以在微博或者公众号把这只充电器送掉,也算是变相支持环保了。

结果没想到的是,如果我想让我的小米11能达到满速55W的充电,那这只充电器可能是送不出去了。

通过下图我自己的测试记录和来自充电头网的数据,在小米10尊享版上,我们看到小米目前的充电协议是可以通过常规PD充电器支持50W以上的快充的,再加上此次小米11有胆量宣传要【取消标配充电器】,所以我自以为此次的小米11也是可以用公有的的PD协议达到50W左右的功率,而非小米私有协议。

然而我找来了手头不同品牌的高功率充电器,他们之中大部分支持PD3.0(PPS),给小米11进行了充电测试后,结果确实令我没有想到。

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。

可能是最详尽的小米11充电功率分析测试

我们先来看下小米11使用原装充电器的表现,功率46W,9V5A的大电流快充协议。

实际上看到这有些知识积累的朋友应该能感到微微不对劲了,因为一般PD协议中50W功率附近是靠握手20V电压来实现的,9V5A依然是魔改协议中低压大电流那一套。这证明随小米11套装发售的这款55W充电器支持的是非常典型的小米私有协议。

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。

但是在配合小米11的实际工作中,这只目前主流的PD充电器却只能有25W的输出。

下面是倍思氮化镓65W二代充电器,依然是当前市面上的主流新品,支持PD3.0,5V/9V/12V/15V/20V的固定电压档位以及一组PPS电压。

在实际测试中,同样只能握手9V电压档位, 功率在26W。

而那些功率档位较少且不支持PPS的PD2.0充电器就更不用说了,联想口红电源只有不到18W的功率输出。当然这也有充电器协议落后的原因,在PD3.0和PPS的加持下不同充电器和终端之间的功率握手更加自由,自然功率会更高一些。

可能是最详尽的小米11充电功率分析测试

通过以上测试我暂时得出结论,在小米11使用原装充电器时可以达到45W左右的功率,更换目前市面上主流的PD3.0充电器时只能在27W上下徘徊。
无线充电

关于无线充电问题多集中在55W立式风冷无线充上。这也是我在张大妈查阅其他帖子时发现错误结论的重灾区。

关于这款产品可以分为两个问题来看。第一,小米11原配55W能否正常触发满速快充;第二,第三方充电器能否正常触发满速快充。

首先我们来看第一个问题。其实这个问题比较简单,稍微有些物理知识的人都知道在使用55W充电器的前提下无论是何种协议都不可能支持无线充同时有55W的输出的,因为无线充电过程中有不可避免的功率损耗。

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。

通过曲线图也可以看出,前十分钟最大功率大部分时间维持在30W左右。而后缓慢降至20W。

可能是最详尽的小米11充电功率分析测试

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。

导致这一问题的原因是PD协议的更新,部分用户手里的65W充电器,如前文有线充电测试中出现的联想口红等依然是PD2.0协议,不支持PPS协议,因此不能与小米立式55W风冷成功握手19V电压。

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】。

同理只要是新款的、支持PPS的65W及以上功率的充电器都是可以实现50W无线充电功率给小米11供电的,这甚至比小米11的有线充电功率还要高上一些。

结论

有线充电:随小米11附送的55W氮化镓峰值在45W上下;第三方PD充电器中,较新的PD3.0充电器可以可以达到27W左右的功率,老款产品由于没有PD3.0而不支持PPS协议,只能握手9V2A档位,功率在18W左右。结论:小米11的高功率充电仅支持小米的私有协议,公有PD协议只能达到最高27W左右。
