Step 3. Open the cover

Before we open the back cover, I will tell you a little secret. The thing is that inside the black rim there is a cover that detaches separately and under it there is a screw that fixes the back cover. We need to use a special suction cup, which we attach to this cover and heat the cover slightly with a hair dryer, then pull the suction cup, push a thin plastic film into the gap, draw it in a circle separating the cover from the adhesive base and detach the cover.

We always need to be careful around the side buttons and the fingerprint sensor, because this area may have cables that can be damaged. We should also be careful in the area of the cameras, so as not to damage the lenses.

And now we have to remove the battery. Traditionally for Honor, we have the three tabs. We need to read the brown tabs on which one we need to pull, and we need to unwrap all of them so that they do not prevent us from detaching the battery and do not hold it.

And as it became clear to us from the description, we have to pull the tab with number 3. Gently pull it upwards, detaching the battery. And with the other hand we hold the display frame on the edges.

As we can see, the battery is also held on the transparent protective coating, which protects the inter-board cable and the display cable.
