Modern smartphone users often face the need to replace the cable or find a compatible charging, but not everyone knows the exact technical name of the interface used in their device. For owners of popular Xiaomi models and the Poco sub-brand, this issue is especially relevant, given the variety of modifications and revisions that have come to the market in recent years. Understanding how to call the charging connector for the Xiaomi Poco phone will help avoid buying incompatible accessories and prevent damage to the gadget.
The vast majority of current models released after 2018 use the USB Type-C standard. This interface has replaced the outdated Micro-USB and has become an industry standard due to its reversibility and high bandwidth. However, there are nuances that every smartphone owner should know about to ensure the long and stable operation of the device.
In this article, we will take a closer look at the port features, its physical characteristics and fault detection methods. Not only will you learn the name of the connector, but you will also understand why some cables charge the phone faster than others. All Xiaomi Poco smartphones, starting with the F1 and M3, use only USB Type-C connector.
Technical name and interface standards
The official name for the connector used to charge and transfer data in Xiaomi Poco smartphones is USB Type-C (or USB-C for short).This is a versatile 24-pin connector that allows you to connect devices from either side, which is its main advantage over its predecessors. The standard was developed by the USB Implementers Forum and quickly gained popularity due to its reliability.
It’s important to distinguish between the physical shape of the connector and the data or energy protocols that pass through it. Although the port itself looks the same on all devices, its internal “stuffing” can support different charging speeds, such as the Quick Charge or the proprietary Xiaomi Turbo Charge. It depends on the quality of the power controller implementation how quickly your smartphone can restore battery power.
Using poor-quality cables can cause the phone to charge slowly, even if the power supply is powerful.The handshake between the charger and the smartphone may not take place if the cable does not meet the necessary specifications.
- 🔌 USB Type-C is a modern standard with a symmetric connector used in all current models.
- ⚡ Power Delivery – a fast charging protocol often supported by a port alongside proprietary technologies.
- 📉 Micro-USB is an outdated standard that is not found in new Poco models, but was in the early Redmi versions.
⚠️ Warning: Do not attempt to insert a Micro-USB cable into a Type-C connector by force. Despite the apparent similarity of size, the shape of the tongue inside the Type-C port is flat and bilateral, and the Micro-USB is trapezoidal. Mechanical impact can cause the central tongue inside the phone socket to break.
Evolution of ports in the Poco and Redmi line
Xiaomi’s smartphone history shows a clear shift from old standards to new ones: early models like the 2018 Poco F1 already featured a USB Type-C port, which was then a sign of a flagship or sub-flagship device.
Starting with 2019-2020 In the past, the company has completely abandoned the use of Micro-USB even in the most affordable models, and Poco M, Poco X and Poco F smartphones have received a unified port, which has made life easier for users who no longer need to search for different cables for their phone, tablet and laptop. However, within the standard USB-C There have also been changes to support charging speeds.
Modern models such as the Poco F5 or Poco X6 are equipped with ports that can withstand currents up to 6 Amps or more, which is necessary for the implementation of 120W HyperCharge technology.
Below is a table showing the evolution of connectors in popular series of devices:
| Smartphone model | Year of release | Type of connector | Max. Charging power. |
|---|---|---|---|
| Poco F1 | 2018 | USB Type-C 2.0 | 18 watts (Quick Charge 3.0) |
| Poco X3 NFC | 2020 | USB Type-C 2.0 | 33 Watts |
| Poco F3 | 2021 | USB Type-C 2.0 | 33 Watts |
| Poco F4 GT | 2022 | USB Type-C 2.0 (magnetic included) | 120 W. |
| Poco X5 Pro | 2023 | USB Type-C 2.0 | 67 W. |
Distinctions between USB Type-C and Micro-USB
Visually, it's pretty easy to distinguish USB Type-C from Micro-USB, if you know where to look. Type-C has an oval, symmetrical shape that allows you to insert a cable by either side. Micro-USB, in turn, has the shape of a trapezoid with two hooks on the bottom, which requires a strict orientation when connecting. On Poco smartphones, you'll never see Micro-USB, since the company has long since switched to a single standard.
While Micro-USB is typically limited to 2 Amps and USB 2.0 data rates, Type-C theoretically supports currents up to 5 Amps (and higher using special E-Marker chips) and data rates up to USB 4.0 or Thunderbolt. For the average user, this means being able to charge fast with high-power current without the risk of overheating.
Another important difference is durability: The Type-C connector is designed for 10,000 insert and retrieve cycles, whereas the Micro-USB can withstand about 5,000 cycles. Given the heavy use of the smartphone during the day, the wear and tear of the charging port is one of the common reasons for going to service centers. Using quality cables helps to extend the life of the connector.
💡
Use the original cables from the kit, as they often have a reinforced design and chips matching the power supply and smartphone for maximum charging speed.
Problems with the charging connector and their diagnosis
Despite the reliability of the standard, the charging connector in Xiaomi Poco smartphones can fail or start to work incorrectly. The most common problem is getting dust, pile and dirt inside the port. Because the phone is often carried in your pockets, small debris is compressed at the bottom of the connector, preventing the cable from entering the end and touching the contacts.
The second common problem is loosening the connector, and over time, the contacts inside the smartphone can weaken, and the cable will hold loose, falling off at the slightest movement, which leads to intermittent charging, which is extremely harmful to the lithium polymer battery, and it is also possible to oxidize the contacts when moisture is ingested, even if the phone was not fully submerged in water.
To diagnose the problem, first of all, you need to visually inspect the port in good light, if you see a dense layer of dust inside, you can carefully remove it. However, the use of metal objects such as needles or pins is strongly discouraged, as you can close contacts or damage the insulation.
- 🔍 Visual inspection – check if there is any dark plaque or compressed dust inside.
- 🔌 Checking the cable – try another good cable to rule out it breaking.
- 📉 Power supply test – make sure the charge adapter is running on another device.
⚠️ Warning: Use only a wooden toothpick or plastic shoulder blade to clean the connector. Metal tools can damage the central plate with contacts, which will lead to irreversible damage to the port and the need to replace it in the service center.
Instructions for safe cleaning of the charging port
If you find that the connector is clogged with dust, it must be cleaned.Be sure to turn off the smartphone before the procedure. This is critical to avoid short circuits if the metal part of the tool (even slightly) touches the contacts under voltage.
Take a wooden toothpick or a plastic toothbrush. Carefully, without pressing too much, walk through the inner walls of the connector, scavenging the dust. You can use a can of compressed air, blowing short bursts, but not bringing the nozzle too close to the speaker hole so as not to damage the membrane.
After mechanical cleaning, wipe the connector with a dry soft cloth. If the problem was dirt, the phone should start charging steadily. If the cable still falls out or charging is jerky, the problem is probably the physical wear of the port itself (the soldering on the board has loosened).
☑️ Checklist for cleaning connector
In some cases, software resetting the power controller settings helps, although this is rare, and you can try completely discharging the phone before turning it off and then charging it when it's off for a few hours, which can help calibrate the battery, but won't solve the problem of physical damage to the contacts.

Choosing a cable and power supply for Xiaomi Poco
For owners of Poco smartphones with support for fast charging, it is critical to use the appropriate accessories. A conventional cable designed for 2A current will not be able to provide power of 33 watts, 67 watts or 120 watts. As a result, the phone will charge slowly, and in some cases the system can limit current even more for security reasons.
Xiaomi’s original cables often have orange labeling inside the connector or a special 6A on the plug, indicating that the cable is reinforced and capable of passing large currents. Using cheap analogues without the support of the necessary protocols can lead to overheating of the cable and even melting of the insulation.
When choosing a power supply, pay attention to support for the Power Delivery (PD) or Quick Charge (QC) protocol. Poco smartphones can negotiate with the charger about the voltage supplied. However, for maximum speed, it is better to use the original charger from the kit or certified analogues from well-known brands (Baseus, Anker, Ugreen) with support for the desired power.
💡
Using the original cable and power supply is the only way to guarantee the manufacturer’s stated charging speed and device safety.
