Use this guide to remove or replace the battery on your Xiaomi Mi 11.
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.
Note: In this guide we’re using a teardown device. This means that the motherboard has been deshielded during the teardown procedure. You can still do all the repairs with this guide but your motherboard will look like this.

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. 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.

Wozu ist denn das weiße Kabel am rechten Rand des Handys? Habe das versehentlich beim öffnen gekillt. Aber ich konnte noch nicht heraus finden was jetzt nicht mehr funktioniert. 😅
Das ist das so genannte Killerkabel.
Ist nur dazu da, dass man sieht, dass schon mal jemand an dem Gerät rumgepfuscht hat.
