Introduction

Use this guide to replace a worn-out or dead battery in your Xiaomi Pocophone F1.

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

Step 1

Before you begin, switch off your phone.
Insert a SIM eject tool or a paperclip into the small hole on the SIM card tray on the left edge of the phone.
Press firmly to eject the tray.
Remove the SIM card tray.
When reinserting the cards, make sure to properly orient them in the tray.

Step 2

Remove the two 2.7 mm-long Torx T3 screws from the bottom edge of your phone.

Step 3

Insert an opening tool between the screen and the back cover at the bottom edge of the screen.
Slide the opening tool to the bottom right corner to release the plastic clips holding the back cover in place.

Be careful to identify the correct groove to attack with the opening tool. The correct groove is the one adjacent to the screen and not the one embossed on the back cover.

Step 4

Slide the opening tool around the bottom right corner.
Slide the opening tool along the right edge of the Pocophone F1 to release the plastic clips.

Step 5

Slide the opening tool along the top edge of the phone to release the plastic clips holding the back cover in place.

Step 6

Slide the opening tool along the left edge of the phone to release the remaining plastic clips.
Try not to remove the back cover all the way yet, the flex cable of the fingerprint sensor is still connected to the motherboard.

Step 7

Carefully fold the phone assembly to the left side of the back cover like you'd open a book page.
Avoid tensioning the fingerprint flex cable during this procedure.

Step 8

Remove the ten 3.2 mm-long Phillips screws.

Step 9

Slide an opening pick under the bottom left corner of the motherboard cover.
Slide the opening pick around the corner and along the left edge of the motherboard cover to release the plastic clips holding it in place.
Use the opening pick to pry up the motherboard cover.

Step 10

Remove the motherboard cover.

Step 11

Use the flat end of a spudger to pry up and disconnect the fingerprint flex connector.
Remove the back cover.

Step 12

Use a pair of tweezers to peel the black protective foil off the battery and logic board and remove it.

Step 13

Use the flat end of a spudger to pry up and disconnect the battery connector.

Step 14

Use the flat end of a spudger to pry up and disconnect the interconnect flex cable.
Fold the interconnect flex cable out of your way in order to get access to the battery.
You might want to use some adhesive tape like tesa and tape the flex cable on your desk to hold it in its folded position.

Step 15

Use a pair of tweezers or your fingernails to peel the orange sticker off the battery.
Peel the small white sticker off the battery.

Step 16

Grab both ends of the orange sticker.
Pull both ends of the orange sticker straight up to lift the battery out of its recess.
If you're having a hard time removing the battery, the adhesive might be a little bit too sticky. You can place a heated iOpener on the screen or use a heat gun to soften the adhesive beneath the battery. Apply the iOpener for at least two minutes.

Step 17

Peel the remaining adhesive off the battery.
Remove the battery.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
You can reuse the old adhesive tape if it's still sticky. However if you want to replace your screen you need to remove it and replace it with new custom cut adhesive tape.

What is the safety hazard with reusing the same battery ? If it has not been damaged, where is the risk ?

Conclusion

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

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.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery.

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

I need advice wich battery to buy and from where.

I can't find a genuine or at least good replacement battery online.

Non of them have a working temperature sensor and most have a lower capacity than advertised.

Xiaomi isn't selling batteries directly to customers in germany.

Did you find any reliable alternative? Having the same problem at the moment. Thinking about going to one of those repair Shops but actually they probably use the same batteries, that I am finding online.

Genuine model reference is BM4E.

Hope to receive it soon !

I struggled with back cover removal. Eventually I've managed to insert the tool between the sim-tray slot and the screen. Just be careful not to break the thin section of plastic.

The battery itself was also harder to remove than expected. The original adhesive is quite strong and the angle you have to pull at is pretty bad.

In the end I was able to complete the battery swap. Thank you for the guide.

Thank you for the tutorial.

After the battery exchange, le phone doesn't charge anymore! Neither with the new battery nor the old one. Charger and cable are OK, tested on another phone. I have double checked the cables in the phone, and loudspeaker is working. Can this be due to a software issue?

Thanks for your help

Regards

Vincent

Thank You!

My Poco F1 has another life to spend.

Bojan -

Thanks for the effort put into this guide! While it may be "old" as the phone, it is still very much appreciated and hopefully will give my phone another couple years of use!

Grazie mille!

If you follow this guide and put in a new battery;

Make sure to align the battery very carefully so that the flex cable lines up with the connector!

I put mine in a bit to the side, which makes it so the flex cable doesn't lie down flat. When reassembling the phone the cable is crushed down, which I think could damage it.

Though it did end up working fine in my case, it felt very sketchy.
