Introduction

Use this guide to replace the battery on your Xiaomi Mi 10 Lite.

If your battery is swollen, take appropriate precautions.

For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

You’ll need replacement adhesive to reattach components when reassembling the device.

Tools

Parts

Step 1

Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Step 2

Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
If the rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.
In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Insert an opening pick into the gap you created.
Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.

Step 3

Insert a second opening pick at the bottom edge of your phone.
Slide the opening pick to the bottom left corner to slice the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 4

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.
Insert a third opening pick at the bottom left corner of your phone.
Slide the opening pick along the left edge of your phone to slice the adhesive.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.

Step 5

Insert a fourth opening pick underneath the top left corner of your phone.
Slide the opening pick along the top edge to slice the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 6

Insert a fifth opening pick underneath the top right corner.
Slide the opening pick along the right edge of the rear glass to slice the remaining adhesive.

Step 7

Remove the rear glass.
Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

Step 8

Use a Phillips screwdriver to remove the ten 3.9 mm-long screws securing the motherboard cover.

Step 9

Insert the tip of an opening pick underneath the right edge of the motherboard cover.
Slide the opening pick to the top right corner of the motherboard cover to unhinge the plastic clips and pry it up.

Step 10

Use a pair of tweezers or your fingers to remove the motherboard cover.

Step 11

Use a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Step 12

Use a spudger to disconnect the interconnect cable by prying the connector straight up from its socket.

Step 13

During the following step do not fold the cable sharply and only bend it to avoid cable damage.
Fold the interconnect flex cable towards the charging port in order to get free access to both battery pull tabs.
You might want to use a small piece of tape to temporarily stick the cable onto your working surface to avoid accidentally damaging it during the battery removal.

Step 14

Take care not to puncture or bend the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a thermal event.
Use a pair of blunt nose tweezers or a clean fingernail to peel the orange adhesive strip labeled with an A off the battery.
Use a pair of blunt nose tweezers or a clean fingernail to peel the orange adhesive strip labeled with a B off the battery.

Step 15

Grab both pull–tab ends labeled with an A and pull up on the orange adhesive strip to lift the battery out of its recess and swing it up to an upright position.
Although these adhesive tabs are supposed to make the battery removal easier, they may require some force. In case you're having trouble removing the battery, you can apply a heated iOpener to the center of the display to loosen the adhesive underneath.
Peel the battery off the remaining adhesive.
Remove the battery.
Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.
During reassembly, temporarily reconnect the battery to the motherboard to help align it correctly. Disconnect the battery after it is seated.

Step 16

In case you're replacing the adhesive sticker with a new one, peel the battery's adhesive sticker off the midframe and clean the relevant areas with isopropyl alcohol (>90%). Let the alcohol dry before installing new adhesive.

Conclusion

If possible, turn on your device and test your repair before installing new adhesive and resealing.

For optimal performance, calibrate your newly installed battery after completing this guide.

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the device at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order. During reassembly apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

Take your e-waste to an R2 or e-Stewards certified recycler.

Seguí los pasos de esta guía pero creo que aunque este punto es válido:

ten cuidado de no sobrecalentar el teléfono--el display y la batería ambas son susceptibles al daño por calor

(Y de hecho el procesador también puede ser dañado si se superan los 100-105º en T-Junction)

Es mucho más probable que ocurra lo contrario: que rompas el cristal templado trasero intentando despegarlo sino has aplicado suficiente calor. Mi recomendación es que tiren muy muy suavemente y sigan calentando hasta que se despegue sin esfuerzo. También que compren una tapa trasera de repuesto por si acaso ya que reinstalar una tapa resquebrajada no es en absoluto recomendable y dejarlo sin tapa, aún menos.

También mencionar que hay que tener especial cuidado con el cable azul que va de arriba a abajo ya que es susceptible de estirarse/romperse al tirar si se queda pegado al adhesivo o que lo rompas involuntariamente al pasar la pua.
