Xiaomi Redmi 5A Disassembly: Step-by-step guide with photo and warnings

Xiaomi Redmi 5A (codenamed riva) remains a popular choice due to its reliability and availability, but even it is not immune to breakdowns. Disassembly of the device may be necessary to replace the battery, repair the charging connector, clean up dust or recover from a fall. However, improper dismantling often leads to damage to plumes, cracks in the case or failure of the microphone / speaker.

This guide will help you disassemble the Redmi 5A without risking internal components, and we will describe each step in detail, from tool preparation to motherboard removal, and point out the hidden latches and brittle elements that are not mentioned in standard manuals. If you have never taken a smartphone apart before, start by reading the section on typical errors: this will save you time and nerves.

Preparation for disassembly: tools and precautions

Before you start, make sure you have everything you need. Xiaomi Redmi 5A is built on glue and latches, so you can't do without specialized tools. Here's the minimum set:

  • πŸ”§ Plastic blade (or mediator) - to disconnect the body without scratches.
  • πŸ”© The screwdriver. PH00 β€” screws 5A Small, regular screwdrivers will rip them off.
  • 🧲 Magnetic mat or tray - so as not to lose the screws (there are 12 pieces!).
  • πŸ”₯ Hair dryer or thermoair station - for softening the glue (optional, but recommended).
  • πŸ“Έ Smartphone for photo capture – take each step so as not to confuse the order of assembly.

⚠️ Warning: Do not use metal blades or knives - they will scratch the body and can damage the plumes. Also avoid excessive heating: temperatures above 60°C deforms plastic and damages the battery.

πŸ“Š You’ve already taken out smartphones before?
Yes, many times.

Before disassembling, be sure to turn off the phone and remove it. SIM-If the battery is swelling, don't try to disassemble the device yourself, go to the service center!

Removal of the back cover: secrets without damage

The Redmi 5A back panel is attached to glue and latches. To remove it, start by warming the edges with a hairdryer (hold it 10-15 cm away for 1-2 minutes) to soften the glue and reduce the risk of cracking.

  1. Insert a plastic blade into the gap between the case and the screen at the charging connector.
  2. Carefully drive the shoulder blade along the edge, alternately snapping clips. There are 8 of them - 2 on each side.
  3. Don't force it! If the lid doesn't lend itself, warm up the problem area again.

⚠️ Attention: The most vulnerable area is the area around the volume buttons, where the button plume is glued to the lid, and it's easy to tear off. If you hear a crunch, stop immediately and check the integrity of the plume.

When you take the lid off, you'll see the battery, the motherboard and the camera. Don't touch the chips with your bare hands, static electricity can damage them. Use an antistatic bracelet or periodically touch a grounded metal object.

Battery shutdown: why it's critical

The battery in the Redmi 5A is soldered to the motherboard, but before any manipulation with the insides, it must be turned off, and even a smartphone that is turned off can get a short circuit if you accidentally close the contacts with the tool.

To disconnect the battery:

  1. Find a black connector with an orange tongue near the battery.
  2. Carefully tuck the tongue with a plastic spatula and pull up.
  3. Make sure that the connector contacts do not come into contact with the charge.

⚠️ Warning: If the connector tongue is broken (a common problem with careless disassembly), do not try to solder the battery yourself. Contact the service - without soldering experience you risk damaging the fee.

What to do if the battery is swelling?
A bloated battery is dangerous! It can ignite or explode when mechanically exposed. If you notice that the back cover has risen or the phone has become thicker: 1. Turn off the device immediately. 2. Do not charge it or leave it unattended. 3. Take it to a replacement service center. Self-disassembly in this case is extremely risky!

Withdrawal of the motherboard: the procedure and traps

The Redmi 5A motherboard has 12 screws attached, but they vary in length. Remember or photograph the location of each screw -- if you confuse it, you can damage the board when you build it.

  1. Unscrew all the screws (start with the corners of the board).
  2. Carefully raise the toll over the edge with a spatula.
  3. Disconnect the plumes: πŸ“± Display (white connector at the top of the board). πŸ”Š Dynamic/microphone (black connector at the bottom edge). πŸ“· Camera (small gray connector).

⚠️ Attention: The plume is extremely fragile, and if it breaks, it costs 30 to 50 percent of the cost of the phone to replace it!

πŸ’‘

If the screw doesn't unscrew, don't force it -- you're probably using the wrong screwdriver. Try the PH000 (still thinner) or drop a WD-40 drop to lubricate the thread.

After the charge is removed, you will get access to all components: charging connector, slot. SIM-Clean them of dust with a soft brush or compressed air (do not use wet wipes!).

Common Mistakes in Disassembly and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when working with the Redmi 5A. Here are the most common problems and ways to prevent them:

  • πŸ”§ Use a high-quality screwdriver and do not tilt it when unscrewing.
  • πŸ”₯ Damage to plumes - do not pull the wires, only for plastic connectors.
  • πŸ’₯ Battery rupture – if it swells, don’t try to remove it without protection (glasses, gloves).
  • πŸ“΅ Lost Details – Magnetic Mat and Photos at Every Stage Will Save You From Chaos.

Another common mistake is the wrong build, for example, if you forget to plug in the power button plume, the phone won't turn on, and you'll look for a problem in the board. Always check the photos you took during the disassembly.

πŸ’‘

The most vulnerable part of the Redmi 5A is the display plume, which costs almost as much as a new phone, so work as carefully as possible or leave it to the professionals to disassemble.

Replacement of the battery: when it is necessary and how to do it

The battery in the Redmi 5A (3,000 mAh) is designed for 300-500 charge cycles. If the phone runs out in a few hours or turns off at 20-30% charge, it is time to change the battery.

  1. Disconnect the old battery (unplug or disconnect the connector if it is not glue-free).
  2. Clear the contacts on the board with alcohol.
  3. Install a new battery (we recommend the original Xiaomi or a quality analogue from Patrona).
  4. Connect the connector and check the work before final assembly.

⚠️ Attention: Cheap batteries from unknown brands can not only quickly fail, but also damage the charging controller on the board.

After you change the battery, calibrate it: completely discharge the phone, then charge to 100% without interruption. Repeat the procedure 2-3 times to accurately display the charge level.

Building a phone: how to avoid mistakes

The Redmi 5A should be assembled in reverse order, but with a few nuances in mind:

  • πŸ”© Screw them in the cross so that the board sits exactly.
  • πŸ“± Trains – make sure they are not twisted and fully entered into the connectors.
  • πŸ”‹ Battery – make sure it doesn’t shift and push the board.
  • πŸ”Š Speaker – press it evenly, otherwise the sound will be distorted.

Before final assembly, turn on the phone and check:

  • Is the sensor and display working?
  • Is the battery charging?
  • Do the volume and power buttons function?
  • Is there sound in the speaker and microphone?

If something doesn't work, take the phone apart again and check the plumes are connected, and most often, problems arise from a loosely inserted display or battery connector.

To make the back cover sit tighter, warm it up with a hair dryer before installation, the glue will become more elastic, and the gaps will be minimal.

FAQ: Frequent questions about the Xiaomi Redmi 5A disassembly

Can you disassemble the Redmi 5A without a hairdryer?
Theoretically, yes, but the risk of damage to the lid or plumes increases by 3-4 times. The glue in the Redmi 5A is quite strong, and without heating the latches can break. If the hair dryer is not, use hot water (put the phone in the bag and lower it in water for 1-2 minutes), but this is less reliable.
What if the phone does not turn on after assembly?
There are several reasons: Display or battery plume is not connected; motherboard is damaged (check for darkening or burning smell); short circuit (unplug the battery and check the board for foreign objects); take the phone apart again and carefully examine all the connectors.
What glue should I use for the back cover?
The best option is a 3M 9448A or Tesa 61396 (0.2 mm thick) double-sided tape. Don't use superglue or heat glue, they will damage the plastic and make it harder to disassemble the next one.
Can I replace the charger by myself?
Yes, but it requires soldering, and it requires soldering dryer, soldering and microelectronics experience to replace it, and if you don't have experience, you should contact the service, which costs about 800-1,500 rubles to replace the connector, and it will cost 3-5 times more to repair the board after a failed soldering.
How much does a Redmi 5A professional disassembly cost?
In service centers disassembly with diagnostics costs 500-1000 rubles. Battery replacement - 1200-1800 rubles (taking into account the cost of the battery), charging connector - 1500-2500 rubles. If you only need disassembly (for example, to clean from dust), look for masters marked "disassembly without repair" - it is cheaper.
