Xiaomi Mi5s was released a few years ago, and over time, its autonomy inevitably declines. If your device stops holding charge, quickly discharges or turns off with 20-30% of the battery, then it's time to think about replacing the battery. This is a common problem for lithium polymer batteries, whose life is limited to the number of recharge cycles.
You can do the replacement procedure yourself at home if you have the tools and basic skills to work with small electronics. However, it is important to understand that opening the body of the Mi5s smartphone deprives you of an official warranty if it was still in effect. In this article, we will discuss in detail the process of dismantling an old battery and installing a new one, paying special attention to safety.
Before you start disassembling, make sure you purchase a quality battery for the Mi5s model, as batteries from other models can differ in size or location of the plume. A poor copy can not only quickly fail, but also damage the power controller of your device. Preparation of the workplace is the first and critical stage of successful repair.
Tools and workplace preparation required
To replace the battery properly, you will need a specialized toolkit to avoid damage to the body and internal components.Using inappropriate items such as regular kitchen knives or metal needles can result in scratches on the aluminum case or, worse, short circuit.
Organize a well-lit space with a flat surface where you can decompose all the parts in order of their dismantling. It is recommended to use a magnetic mat or small screw containers, as Xiaomi Mi5s use mounting elements of different sizes, and it is very easy to confuse them.
- 🔧 Precision screwdrivers (cross-haired) P2 and P5) cock-wheel.
- 🔥 A hair dryer or heating pad for heating the glue layer under the back cover of the smartphone.
- 💳 Plastic card or mediator for neat opening of the case without damage.
- 🧲 Magnetic substrate for systematization of twisted screws of different sizes.
- 🧤 Antistatic gloves to protect electronics from static electricity.
Pay special attention to the warming of the back cover, as it is planted on a fairly aggressive glue. Insufficient heating will cause the cover to crack when you try to open, and excessive - can damage the display or internal components.
💡
Use an infrared thermometer to control the heating temperature of the back cover - the safe range is 80-90 degrees Celsius, it is already dangerous for the screen matrix to warm higher.
Rear cover removal and protection of internal components
Xiaomi's autopsy process Mi5s Starts by turning off the device and removing the tray SIM-After that, you need to warm up the perimeter of the back cover, evenly passing the hair dryer throughout the circuit during the course of the process. 2-3 Do not hold the hair dryer at one point for too long, so as not to overheat the local areas of glass or metal.
⚠️ Warning: Do not try to lid until it is warmed up well enough - model glass Mi5s very fragile and will burst at the slightest distortion, if the glue is not softened.
After warming up, insert a plastic card or mediator into the junction between the lid and the frame at the bottom of the smartphone. Carefully guide the tool along the perimeter, gradually cutting the adhesive layer. Move slowly, without making sharp jerks, so as not to damage the fingerprint scanner plume that may be glued to the lid.
Once the lid is removed, flip the smartphone over and remove the protective metal plate that covers the connectors. To do this, twist a few screws around the perimeter of the board and carefully remove the metal, trying not to catch the plumes. Under this plate is the motherboard and connectors, which are connected to the main modules.
Features of the Mi5s design
Disconnecting plumes and removing the old battery
After removing the metal protection, you will have access to the main nodes of the smartphone. The first thing you need to do is disconnect the battery plume from the motherboard to turn off the device and avoid short circuits during further operation.
Use a plastic blade to detach the connector, pressing strictly upwards. Then unscrew the screws that hold the speaker board and the battery itself. In the Mi5s, the battery is also planted on glue, so removing it requires re-heating, but very carefully, the back of the case.
| Component | Type of attachment | Features of withdrawal |
|---|---|---|
| Back cover. | Glue + screws | It requires a strong warm-up hairdryer. |
| Metal protection | Screws (P2) | Easy to remove after twisting |
| Battery | Adhesive tape | Heat and neat smacking are needed. |
| Payment dynamics | Screws + plume | Requires disconnection of the connector |
You can use a suction cup or a thin plastic card to pull it out, and if the battery is sitting very tight, you can use a small amount of isopropyl alcohol around the perimeter to dissolve the glue, but you have to be very careful.
Installation of a new battery and assembly of the device
Before installing a new battery, clean the seat of old glue and dirt. The new Xiaomi Mi5s battery must be applied special adhesive strips (usually included) to fix it in the case and prevent displacement when falling.
Connect the new battery plume to the motherboard before you click, making sure it's up straight. Don't turn the phone on right away -- check all the connections first and make sure no plume is squeezed. Only after visual inspection can you start to reverse assemble.
- 🔋 Install a new battery in a niche and press tightly around the edges to fix the glue.
- 🔌 Connect the display connector and test run (if required).
- 🔩 Install a metal protective plate in place and twist all the screws.
- 🧹 Wipe the inside of the back cover from dust and fingerprints.
- 🔒 Stick a new glue frame for the back cover and tightly press the body.
To fix the back cover, use a special glue sealant or ready-made adhesive circuit (B-7000 or analogues). Apply a thin layer of glue around the perimeter of the frame, combine the cover and tightly press the device with rubber harnesses for 15-20 minutes before the initial grasp.
☑️ Post-assembly check
First start and calibration of the battery
Once the device is assembled, you need to start and calibrate the new battery correctly, which will help the power controller display the charge level correctly and extend the life of the new battery, turn on your smartphone and wait for the MIUI operating system to fully load.
It is recommended to completely discharge the device before turning it off, and then charge it to 100% when it is turned off. After reaching full charge, leave the phone on charge for another 1-2 hours, this cycle will help the system to re-determine the capacity and characteristics of the batteries.
⚠️ Warning: If the battery shows the wrong percentage of charge after replacement or the phone turns off when the battery is replaced 30-40%, You may need to reset battery statistics through an engineering menu or repeat the charging-discharge cycle.
In some cases, after the battery is replaced, the system may issue a warning about an unoriginal battery. This is normal for third-party components and does not affect the operation of the device if the battery is of good quality. However, if the phone warms or quickly sits down, it is worth checking the energy consumption in the settings.
💡
Proper calibration in the first days of operation is the key to accurately displaying the charge and long-term operation of your Xiaomi Mi5s without sudden shutdowns.
Possible problems and ways to solve them
During the replacement process, various technical difficulties can arise that require careful analysis, and most often users are faced with the fact that the phone does not turn on, does not see. SIM-Fingerprint scanner or not working after assembly.
If the device does not respond to the power button, check the density of the battery plume connection and make sure that it is not damaged. It is also worth checking the condition of the connector on the board itself - oxidation or bent contacts can prevent power from being supplied to the electronics of the smartphone.
If you have problems with your fingerprint scanner (if it stopped working after being replaced), take a close look at its plume. In the Mi5s, it is very thin and easily breaks when you open it in a sloppy way. If the plume is intact, try reinstalling its connector by pre-energizing the device.
