When choosing accessories for Xiaomi smartphone, many are faced with the question: what is the charging and data connector used in a particular model? The type of connector depends not only on compatibility with cables and chargers, but also on the speed of charging, the ability to connect external devices, and in some cases even the functionality of a smartphone. For example, USB-C supports fast charging and video output to external displays, while the outdated microUSB is limited in capabilities.
In this article, we will look at what connectors are used in Xiaomi phones from budget Redmi to flagship Mi and POCO. You will learn how to determine the type of connector by appearance, which models support reverse connection (when the cable can be inserted by either side), and what to do if the connector is damaged. We will also compare the advantages and disadvantages of each type and give recommendations for choosing cables for long-lasting operation.
The evolution of connectors in Xiaomi smartphones: from microUSB to USB-C
Xiaomi launched the mass-produced smartphone in 2011, and during that time, the connectivity standards have changed several times. Until 2016, most models were equipped with a microUSB 2.0 connector — compact but uncomfortable due to the lack of reversibility (you had to flip the plug). The first smartphone brand with USB Type-C was the flagship Mi 5, released in 2016. Since then, the transition to the new standard has been gradual:
- 📱 2011–2015 – microUSB only (e.g. Mi 1, Mi 2, Redmi 1).
- 🔄 2016-2018 – mixed period: flagships (Mi 5, Mi 6) received USB-C, a) Budgetary models (Redmi) 4A, Redmi 5 remained on microUSB.
- ⚡ 2019–2026 – full transition to USB-C In all series, including the Redmi Note, POCO and Black Shark.
It is important to note that even after the transition to USB-C, not all models support the same protocols. For example, Redmi 9A (2020) has a USB-C connector, but is limited to USB 2.0 data transfer speed (up to 480 Mbps), while Xiaomi 13 Pro (2023) supports USB 3.2 Gen 1 (up to 5 Gbps) and DisplayPort for image output.
How to determine the type of connector in your Xiaomi: 3 ways
If you’re not sure what connector is used in your smartphone, there are a few simple ways to check it out:
- External examination: 🔍 USB-C: oval connector without "top" and "bottom" (inserted by either side), usually symmetrical. 🔌 microUSB: trapezoidal connector with a noticeable "upper" and "lower" side (if the connection is incorrect, it does not enter the device).

For convenience, we have compiled a visual comparison:
| Type of connector | Appearance | Features | Examples of Xiaomi models |
|---|---|---|---|
| USB-C | Oval, symmetrical | Reverse, supports fast charging | Mi 11, Redmi Note 10, POCO X3 Pro |
| microUSB | Trapez, asymmetrical | Only one side to connect | Redmi 4X, Mi 4, Redmi 3S |
💡
If the connector is visually damaged (bent contacts, loose port), do not try to insert the cable by force, this can lead to a short circuit.
USB-C vs microUSB: What’s Better and Why Xiaomi Has Dropped the Old Standard
Xiaomi’s move to USB-C was not an accident, but a consequence of several key advantages of the new standard:
- ⚡ Charging speed: USB-C Supports Quick Charge (Power Delivery) protocols, while microUSB is limited to 10-15 watts.
- 🔄 Reversibility: cable USB-C You can insert by any side - convenience, which is deprived of microUSB.
- 📤 Transfer of data: USB-C In modern models, it supports USB 3.2 (up to 10 Gbps), while microUSB is limited USB 2.0 (480 Mbps).
- 🎮 Multimedia: through USB-C You can connect monitors (DisplayPort Alt Mode) or game controllers, which is not possible with microUSB.
However, microUSB has one advantage – cheap accessories. Cables and chargers for it are still widely available and cost 2-3 times cheaper than quality USB-C. But given the fact that even low-end Xiaomi models (for example, Redmi 10A) are now equipped with USB-C, the choice is obvious.
⚠️ Note: Not all cables USB-C Cheap uncertified wires may not support fast charging or even damage your smartphone. USB-IF Certified or from trusted brands (Anker, Baseus).
List of Xiaomi models by connector type (2015–2026)
To be sure, we put together a table with popular Xiaomi, Redmi and POCO models, separated by connector type, and note that even within the same series (for example, the Redmi Note) there could be different standards.
| Series | Models with microUSB | USB-C models | The year of transition to USB-C |
|---|---|---|---|
| Xiaomi Mi | Mi 1–4, Mi Max, Mi Note | Mi 5–14, Mi Mix, Mi 11 Ultra | 2016 |
| Redmi | Redmi 1–5, Redmi Note 3–5 | Redmi 6–12, Redmi Note 6–13 | 2018 |
| POCO | — | POCO F1–F5, POCO X3–X6 | 2018 (from the first generation) |
| Black Shark | — | Black Shark 1–5 | 2018 (Gaming smartphones directly on USB-C) |
If your model is not in the table, check its specifications on the official Xiaomi website or in the GSMArena database. For example, Redmi 9C (2020) has a microUSB, despite the late year of release - this is an exception to the rule.
Why are some new Xiaomi models still coming with microUSB?
What to do if the smartphone connector is damaged: repair or replacement
Connector damage is one of the most common problems with Xiaomi smartphones, especially if you often connect charging or use poor-quality cables.
- ⚡ The phone is not charging or charging is interrupted.
- 🔌 The cable is not fixed in the connector (falls out at the slightest movement).
- 📱 The screen displays a notification saying, "Charging is suspended. Check the cable".
- 🔥 The connector warms or smells of fire.
Depending on the degree of damage, there are several solutions:
- Clean connector: often the problem lies in accumulated dust or oxidation of contacts. Carefully clean the port with a wooden toothpick (not metal!) and blow with compressed air.
- Cable replacement: If the connector is externally intact, but charging is not going, try another cable (preferably original or certified).
- Repair in the service: if the contacts are bent or torn, you will need soldering or replacement of the connector. The cost of repair in official Xiaomi services is from 1,500 to 3,000 rubles.
- Wireless charging: For models with Qi support (e.g. Mi 11, Xiaomi 13) wireless chargers can be used.
⚠️ Warning: If the connector not only does not work, but also has traces of melting or burning, do not try to charge the phone - this can lead to fire.

Connector compatibility: can adapters be used?
If you have old accessories with microUSB and your new smartphone is equipped with USB-C, or vice versa, can you combine them? Technically yes, but with the caveats:
- 🔌 MicroUSB adapters → USB-C: There are adapters, but they often don't support fast charging and can overheat. Example: Redmi charging adapter 4X from the Xiaomi 12 block.
- ⚡ USB-C → microUSB: such adapters are rare and usually uncertified. their use can damage the port of the smartphone.
- 📱 Wireless solutions: it is better to use Bluetooth accessories (earphones, keyboards) or OTG-hub.
It's important to understand that adapters are a temporary solution, and they reduce the reliability of the connection and can lead to:
- Slow charging (even if the block supports Quick Charge)
- Overheating of the connector or cable.
- Loss of data during file transfer.
If you need an adapter, choose models with a USB-IF certification and a voltage control chip. For example, the Baseus USB-C to microUSB adapter supports current up to 2A, but does not guarantee fast charging.
💡
Better to buy a quality cable with the right connector once than risk a smartphone using cheap adapters, especially for flagship models that support Quick Charge 4+ or Power Delivery.
The future of connectors in Xiaomi smartphones: what awaits us next
From 2026, the European Union has obliged all smartphone manufacturers to switch to USB-C as a single standard, which means that even if Xiaomi wants to return microUSB to budget models, this will not be possible for the EU market.
- 🔌 Complete port abandonment: some flagships (for example, Xiaomi 14 Ultra) may lose the physical connector in the future in favor of wireless charging and data transmission over Wi-Fi 6E or UWB.
- ⚡ Universality USB-C: new versions of the standard (USB4) will allow you to transmit data at speeds up to 40 Gbit / s and connect external GPU.
- 🔋 Wireless technology: Xiaomi is already testing charging at a distance (up to 1 meter) and reverse wireless charging for accessories.
However, a complete abandonment of wired connectors is unlikely in the next 5 years - they are still necessary for:
- Fast charging (wireless solutions are still inferior in speed).
- Connect to a computer for firmware or debugging.
- Uses VR-helmets or external storage devices.
USB-C will remain the standard for Xiaomi until at least 2030, and possibly longer, until wireless technology becomes as reliable and fast.
