What connector is installed in the Xiaomi Redmi Note 5: types, compatibility and replacement

Owners of the popular Xiaomi Redmi Note 5 smartphone (known in China as the Redmi Note 5 Pro) often face the need to replace the batteries or charging ports. The question of what connector is used in this model becomes critical when ordering repair parts. Mistake in choosing the type of connector can lead to the fact that the device will not charge or transmit data, and in the worst case, damage the motherboard.

In this article, we will discuss the specification of the interface used in the Redmi Note 5, and answer questions about compatibility with other models. Understanding the technical nuances will help you avoid unnecessary costs and choose the right part to restore the functionality of the gadget. We will look at both standard ports and plume features for different regions.

It is worth noting that Xiaomi has released modifications of devices with different components at different times, but there is a well-established standard for this model. Below we will provide comprehensive information that will be useful for both independent craftsmen and those who plan to hand over the phone to the service center and want to control the process.

Interface type and data transmission standards

The main connector for charging and synchronization in the Xiaomi Redmi Note 5 is the classic Micro-USB port. This is the Micro-B standard, which was dominant in the smartphone industry before the mass transition to USB Type-C. It is important not to confuse it with more modern analogues, since the physical shape and location of the contacts are radically different.

Although the device supports Quick Charge fast charging technology, the physical connector itself remains in the Micro-USB form factor. This means that the current throughput is limited by the capabilities of this connector, but for the 2018 model, this is a regular and fully operational configuration.

⚠️ Note: Attempting to physically insert the cable USB Type-C in a Micro-USB connector without an adapter can cause tongue breakage inside the port and damage to the contacts on the motherboard.

When ordering a part, it is important to pay attention to support for fast charging. Some cheap connector analogs may not have the necessary contacts or use low-quality metal, which will lead to heating and loss of charging efficiency.

• 🔌 Type of connector: Micro-USB (Micro-B).
• ⚡ Support for fast charging: Yes (QC 2.0/3.0).
• 💾 Data transfer speed: up to 480 Mbps (USB 2.0).
• 🛡️ Protection: Often has a dust curtain (depending on the plume version).

Coil design and model compatibility

In the Redmi Note 5, the charging connector is not soldered directly to the board, but is displayed on a separate flexible plume (sub-board flex cable), which simplifies the replacement process: the wizard does not need a soldering iron and a hair dryer, just unscrew a few screws and replace the module as a whole.

The Redmi Note 5 (codenamed whyred) has a specific layout of the lower board. The plume connects the main motherboard to the lower board, on which the Micro-USB connector, microphone and antenna contact are soldered. When buying it is important to look for the plume marked specifically for the Redmi Note 5 / Note 5 Pro.

There's a common misconception that all the Redmi Note plumes are universal. It's not. The differences can be minimal: a millimeter shifted connector, a different microphone positioned, or a different antenna conductor length, and installing an inappropriate plume can cause you to simply not be able to close the case or the phone to not catch the network.

Signs of a faulty charging connector

You can understand that the Micro-USB connector on your Xiaomi Redmi Note 5 requires replacement, for a number of characteristic symptoms. Most often, the problem lies in mechanical wear of the “tongue” inside the port or loosening of the soldering contacts (although in the case of a ration train, the ration is excluded, but contact with the main board may be disrupted).

The first bell is to look for the "position" where the phone starts charging, and if you put the phone on the table and the charging stops, or if the cable has to bend at a certain angle, it's a clear sign of wear and tear in the contact group, and there can also be an intermittent connection when charging goes on, then disappears for no apparent reason.

💡

Before replacing the plume, try cleaning the connector with a toothpick or soft brush, often with compressed dust and pile that prevent the cable from entering the end and closing contacts.

Another symptom is the lack of data transmission: If the computer can’t see the phone when it’s connected by a cable, even though it’s been seen before, and charging is ongoing (albeit intermittently), the data connections (Data+ and Data-) are likely to be damaged, in which case replacing the plume will also solve the problem.

• 📉 The phone only charges in a certain position.
• 🔋 The charging indicator is constantly blinking or disappearing.
• 💻 The computer does not recognize the connected device.
• 🔥 Strong heating at the bottom of the smartphone while charging.

Replacement process of charging plume

Replacing the plume in the Redmi Note 5 is a medium-sized repair, requiring a set of screwdrivers (cross), a plastic spatula (mediator), and preferably a suction cup to carefully remove the back cover. The main rule is to act slowly and not to exert excessive effort so as not to damage the fragile plumes of the display or cameras.

First, you need to turn off the device and remove the tray. SIM-Then, warm up the edge of the back cover (if it's glued, although it's more likely to be held on screws and latches in the Note 5), gently flick it around the perimeter. Once you remove the cover, you'll see the battery and the bottom plastic bar covering the plumes.

Unscrew the bottom bar screws and battery protection plate, disconnect the main battery plume from the motherboard for safety. Next, unplug the old charging plume from the board and remove it. Install a new component, tightly snap the connectors, assemble the phone in reverse order and check the health.

⚠️ Warning: Be sure to turn off the battery before any manipulation of the plumes!A short circuit of the charging plume connector on the board on can disable the power controller.

Selection of the original spare part

The Xiaomi parts market is full of different quality copies. The original Redmi Note 5 plume is usually labeled by the manufacturer and is made of a denser but more flexible material. Cheap counterparts are often too rigid, making it difficult to stack, or too thin, causing them to quickly rub.

Pay attention to the color of the contacts. In quality, they have a uniform golden or nickel hue without oxides. Also important is the accuracy of the screw holes: if the holes in the plume do not match the holes in the body, you will have to drill a new part or break the case, which is unacceptable.

Another important aspect is antenna contact, which is that the charging plume often has a spring-loaded pin or metallized pad that presses against the antenna, and if this element is shifted on the copy, the phone will have a drastic deterioration in the quality of GSM and Wi-Fi reception.

💡

The quality of the antenna contact on the plume directly affects the signal level of the cellular connection, and cheap copies often lack the correct resistance of this contact.
