How to change the charging socket on the Xiaomi phone: repair with your own hands

Charging problems are one of the most common malfunctions of Xiaomi, Redmi and POCO smartphones. The phone charges, then it doesn't, the cable has to be kept at a certain angle, and sometimes the device stops responding to the connection to the network, and 90% of the time the charging socket (also a USB-C or Micro-USB connector) is to blame, which over time weakens, oxidizes or goes off the board.

Many users run to the service center immediately, but you can replace the connector yourself — with patience, minimal soldering skills and the right tools. In this article, we will analyze all the stages of repair, from diagnosis of breakdown to testing after replacement, you will learn which Xiaomi models are most affected by this problem, how to choose a quality socket, and what to do if the phone does not charge after replacing.

⚠️ Important: Electronics repair requires care. If you've never held a soldering iron, it's best to consult a specialist - wrong actions can damage the motherboard or even fire.

Signs of a faulty charging socket

Before you disassemble the phone, make sure that the connector is the problem.

• 🔌 The phone charges only in a certain position of the cable (you have to bend it or press it).
• ⚡ Charging is interrupted on its own, although the cable and power supply are serviceable.
• 📱 The device does not respond to the connection to the PC (no connection sound, not defined as a drive).
• 🔋 The screen displays a notification saying, “Charging suspended. Humidity in the connector” (even if the phone is dry).
• 🔥 The connector is shattered, luftite or has visible damage (blackened contacts, chips).

If any of these signs show up, there's a 95% chance the nest is at fault, but check before you repair them.

1. The cable and power supply are faulty (try charging another phone).
2. No dirt in the connector (clean it carefully with a toothpick or compressed air).
3. Phone Settings: Sometimes the problem lies in a software failure (reboot the device or reset the settings to Settings → System → Reset settings).

Which Xiaomi models are more likely to break down?

Some Xiaomi smartphones are particularly prone to breakages of the charging socket due to design features or the use of poor-quality connectors.-5 «Record holders" on appeals to service centers:

Important for owners of the POCO X3 and Redmi Note 9: these models have additional protection against moisture (IP53), but it does not save from oxidation of contacts when liquid enters. If the phone stopped charging after getting wet, be sure to check the corrosion fee before replacing the socket!

If your model is not in the table, don’t worry – the process of replacing the socket on most Xiaomi smartphones is similar.

Selection of a new charging socket: original vs. analog

The quality of the connector depends on how long it will last after replacement, and here's what to look for when buying:

• 🔍 Type of connector: USB-C Micro-USB (check your model!).
• 🏷️ Article: Look for a connector marked "For Xiaomi [model]." For example, for the Redmi Note. 8 fitting a nest with an articular XM-208-01.
• 🔧 Razing quality: In the original connectors, the contacts are coated with gold (not oxidized.
• 📦 Set: In good sets there is a sealing ring and fastening screws.

Where to buy:

• 🛒 AliExpress - cheap analogues (from 100) ₽), But the risk of marriage.
• 🏬 Local parts stores – originals or certified copies (300-800) ₽).
• 🔧 Service centers – you can buy a spare part with a warranty (1000-1500) ₽).

💡

Before buying, check the reviews on the connector! Often the comments will say whether it fits a particular Xiaomi model and how long it lasts.

⚠️ Warning: Don’t buy connectors without a metal case – they quickly unwind. Also avoid Chinese “nouneim” brands with suspiciously low prices (less than 80). ₽).

Tools for replacing the charging socket

For repairs you will need:

Sweater iron (power 30–40 W) with a thin sting |Sweat and flux (better to use Tinol or RMA-223) |Sweater or braiding suction |Tweeders and plastic mediators for disassembly |Multimeter (for checking contacts) |Isopropyl alcohol (90%+) and cotton swabs |Fen (for heating up the fee if necessary) |Croswriver (usually PH00 or PH0)|>

If you don't have a soldering iron, you can use a thermal air station (it's safer for boards), but it's expensive equipment, and a regular soldering iron is also suitable for a one-time replacement, the main thing is not to overheat the contacts.

⚠️ Note: Do not use soldering irons with more power 60 Watts — they can melt the tracks on the board. Also avoid acid fluxes (for example, LTI).-120), They're eating away at contacts.

Step-by-step instructions for replacing the nest

Now, let's get to the repairs themselves, follow the instructions strictly to ensure that you don't damage your phone.

1. Disassembly of the telephone

Each Xiaomi model is different, but the general algorithm is as follows:

1. Turn off the phone and remove it. SIM-map + memory-card.
2. Heat the back cover with a hairdryer (temperature ~60°C) - this will soften the glue.
3. Carefully apply the lid to the plastic mediator, starting at the corners. Redmi Note and POCO often have latches - don't break them!
4. Unscrew all the screws on the metal screen (they are of different lengths - remember where you were!).
5. Disconnect the battery and display plumes (use a plastic shoulder blade).

2 Removal of the old nest

The most important stage:

1. Cover the contacts around the nest with flux (this will help the solder to melt evenly).
2. Heat each contact with a soldering iron for 2-3 seconds, then remove the solder with a suction or swipe.
3. Carefully tweez the connector and remove it from the board. Don't force it -- if the contacts don't solder, warm it longer!
4. Clean the contact areas on the board with alcohol and check their integrity (are there any detachments).

⚠️ Attention: If you remove the nest, the contact pads come off, the repair becomes more complicated, you have to solder the wires directly to the board or restore the tracks - this is a professional job.

3. Installation of a new nest

Now, we're going to put a new connector.

1. Check if the contacts on the new nest match the old one (sometimes they are mirror-inverted!).
2. Apply a thin layer of flux to the contact boards.
3. Set the nest in place and fix it with tweezers.
4. Salt every contact, starting with the ground (usually the outer legs). Don't save solder - the contact must be reliable.
5. Check with a multimeter if there is a short circuit between the neighboring contacts.

💡

After soldering, do not move the nest for 2-3 minutes - the solder should completely harden.

4. Assembly and testing

Collect the phone in reverse order:

1. Connect the display and battery plumes.
2. So, turn all the stains (not to be worn).
3. Stick the back cover (use double-sided scotch or B-7000 glue).

After assembly:

• Try charging your phone with different cables.
• Connect to the PC - the device must be determined.
• Check if there is overheating in the nest area (if warmed - bad contact!).

What if the phone does not charge after replacement?

If the replacement of the nest did not solve the problem, the reasons may be as follows:

• 🔌 Bad ration: Recheck all contacts with a multimeter. Often, "plus" or "mass" goes away».
• 🔋 Faulty Charging Controller: There is a chip on the board that controls power (e.g, BQ25890 It can burn up when you short it in Redmi Note 8.
• 📱 Firmware problems: Sometimes a software failure blocks charging. Try resetting or reflashing your phone.
• 🔥 Factor damage: If the rations overheated the tracks, they could peel off.

If you are confident in your skills, you can try reflashing the charging controller through EDL-Mode (you need a box like UFi or EasyJTAG) but without experience, it's better to bring the phone to the service.

💡

If the phone charges very slowly (e.g. 1% in 30 minutes), the problem may be the thermistor resistor (which is responsible for determining the type of cable) which can be replaced, but it is a piece of jewelry.

How much does it cost to replace a nest in the service?

If you don’t venture to repair your phone yourself, here are the average prices at service centers (2026):

⚠️ Note: Xiaomi's official service may be denied warranty repairs if the phone has already been opened, POCO F3) have seals on the screws - their damage will void the warranty.
