Replace the battery Step by step for beginner

1. Switching off your iPhone 11 Pro and Removing the Pentalobe screws.


Turn off your iPhone after testing to avoid a potential short circuit during the repair. Unscrew the two Pentalobe screws with a special Pentalobe screwdriver.

We recommend that you use a screw storage to avoid losing any of the removed parts or screws or magnetic pad on which you can arrange the parts as they were installed in the phone. 

2. Heating up the screen and Lifting up the iPhone 11 Pro display.


Heat the edge of the display by running the heat gun evenly. Placing a suction cup on the bottom edge of the display and pull it slowly upwards to create a narrow gap between the display and the case. Then insert a flat hard plastic plectrum into the gap to enlarge it.

3. Detaching the display

Move the hard-plastic plectrum once completely around the display frame. Press it upwards at the same time to release the hooked lugs of the display from the rear case. Then open it towards the standby button.

4. Detaching the battery connectors and Detaching the display connectors


The iPhone 11 Pro battery has two connectors, one on the logic board and one on the lightning connector. The procedure is the same for both connectors:

First remove the bracket plate over the battery connector by unscrewing the Y-type screws. Then use a plastic spudger to move under the connector and carefully separate it from the board.

The display connectors are detached from the logic board. Remove the display connectors with same procedure.

5. Detaching the Lightning connector and removing the Taptic Engine


The battery of the iPhone 11 Pro is fixed in the case from three sides with adhesive tape. To make it easier to remove the adhesive strips, we recommend that you first detach the Lightning connector and remove the bracket plate over the Lightning cable set.

Then separate the two connectors of the Lightning connector by carefully lifting them off the logic board with a spudger.

Detach the Taptic Engine connector by carefully lifting it off the USB board with a spudger. Loosen the three screws that hold the Taptic Engine in place. 

6. Removing the battery and preparing the new battery


The battery is glued in with three adhesive strips. These can be pulled out by their tabs, which are attached to the edge of the battery. To begin, remove the black tabs of the adhesive strips from the edge of the battery using tweezers.

Pull the adhesive strips slowly one after the other from under the battery. Pull them out as flat as possible so that they do not tear. When all the adhesive strips are released, you can remove the battery.

Once the old battery is removed, you can prepare your new spare battery by applying adhesive tape to it. Align the adhesive strips on the back of the battery as a test. Remove the blue protective foil and attach the adhesive strips to the battery.

7. Inserting the battery and the Taptic Engine


If the replacement battery is provided with battery adhesive strips, it can be inserted. First remove the pink protective foil from the adhesive strips. Then press the battery firmly onto the bottom of the rear case.


After the new battery is installed, the Taptic Engine can be inserted again. Reattach your connector on the lightning connector by carefully pressing it until it clicks into place audibly and perceptibly.

8. Attaching the Lightning connector, the display connectors, and the battery connectors.


Also reconnect the Lightning connector and fix its cable with the cover plate. Attach the two connectors on the logicboard by gently pressing them until you hear and feel them click into place. Position the bracket plate over the flex cable and screw it to the edge of the rear case.


At this point you can reconnect the display to the logicboard. Lean the display back against a stable object to avoid overstretching the flex cables when connecting them.

Attach the three display connectors by carefully pressing them one after the other on the logicboard. Position the bracket plate over the attached connectors and fix it with the six Y-type screws.

Carefully press the battery connector on the board so that it clicks into place audibly and noticeably. Position the bracket plate over the connector and screw it on.

9. Testing your iPhone 11 Pro and installing the display


To make sure that the repair was successful, we recommend that you test your device before you glue and screw it back together with screwdriver. For this purpose, use our checklist again.

If something went defective after the repair, check again if everything is properly installed and connected.


Carefully fold it over and press it evenly into the rear case, so that it clicks into place. At the end of the repair the display must still be screwed. Fasten the Pentalobe screws left and right of the Lightning connector
