Then we need to heat the surface of the back cover to a temperature of about 70 ° C or 160 ° F for this we use a heating mat you can use a hair dryer for 5-7 minutes.
To detach the back cover, we use a thin metal tool first. Because of the fact that the edge of the middle cover slightly protrudes over the back cover, we need to slightly pry the back cover to create a small gap in which we can insert the plastic film and work the plastic film as a tool to detach the back cover.
So we find a convenient place for us, pry up the back cover, insert the plastic film and start to run the plastic film along the back cover. In our case, the plastic film is a display protective film, they come in different thicknesses in our case it is thicker. And we need to be careful in the area of the side buttons and fingerprint sensor because in this place are usually located cables. We also have to be careful around the cameras so we don't damage the lenses.
Step 4. Unscrew the screws
We use a 1.5mm Phillips or #000 screwdriver to unscrew the six long black screws.
If the screws are different, we should take a picture of them or put them on a special surface in a certain order so that we don't mix them up when reassembling.

The motherboard, also, may be attached with attachments like latches or hooks, be careful.
⚠️️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.
Step 18. Remove the battery
Finally, we move on to detaching the battery.
We need to unwrap the brown tabs with the letters A and B on them. As we can see on the tab with the letter, A, there is a description and the sequence in which we should proceed.
We read what is written on the tab and act according to what is written. We have to pull the A tab upwards. The one that's wide.
Gently pull and detach the battery. As we see the battery from one edge is held on a transparent coating, which protects the cables under the battery.
