iPhone 8 plus Battery Replacement By How-FixIT

Hello everyone, today I show you how to completely disassemble iPhone 8 Plus and replace backcover To disassemble the iPhone 8 Plus you need the following tools: • Screwdriver set • Plastic mediator • Suction cup for removing display • Tweezers and opening plastic tool • Hairdryer In the description under this video, I left links to the necessary tools and parts for replacement. Before disassembly, turn off the iPhone and remove the tray with the sim card. Take a screwdriver Pentalobe 0.8mm and unscrew the two screws near charging port. Take a hair dryer and heat display surface for 1-2 minutes. Next, fix the suction cup near home button and pull up on the ring. Take a plastic mediator and try to separate the display from the iPhone.

If you cannot separate using a mediator, you can take a plastic card. Open the display to the right side like a book. Unscrew 4 screws and remove the metal panel. I also recommend using a magnetic mat when disassembling the iPhone 8 plus and lay out screws in the order of the disassembly process, because all screws are of different sizes and it is enough just to get confused during assembly. Disconnect the battery cable from the iPhone mainboard.

Unscrew 2 more screws and remove the metal panel. Now you can disconnect 3 cables of display from mainboard. To replace the battery, you need to remove the Taptic Engine. Unscrew the 3 screws and remove the metal panel. Now unplug the antenna, disconnect it from the mainboard and remove from the case.

Disconnect the Taptic Engine cable and unscrew the 3 screws. Now you can remove the Taptic Engine. Take tweezers and catch on the edge of the silicone tape. Slowly pull the silicone tape away from the battery. Similarly, remove the remaining 3 silicone adhesive tapes from under the battery.

Now you can remove and replace the battery. In the description under the video, you find links where you can buy a new battery for iPhone 8 plus. A new battery must be gluing to the metal part of the case, but don't glue the battery to the wireless charging module. You can glue the battery with double-sided tape or with special silicone tapes, similar to the original tapes that you removed from the battery. In my case, I glue on double-sided tape, because right now I don't have silicone tape.

Install the Taptic Engine, fix with 3 screws and connect the cable. Install the antenna and connect to the mainboard. Install the metal panel and fasten 3 screws. Now you can connect the display and check how the iPhone works with the new battery. To check the functionality of all smartphone functions, it is enough to connect three cables from the display module and then the battery cable.

Turn over the display, turn on the phone and check how the iPhone works. Remove the old adhesive tape from the iPhone case. Take the medical alcohol and wipe the case. Also, wipe the display case. Now begin to restore the water resistance of the iPhone 8 plus.

For this, take a waterproof adhesive tape. A link to this adhesive tape you can find in the description under the video. First, connect 3 cables of the display module to the iPhone 8 plus mainboard and only then connect the cable from the battery. Install the metal panel and fasten all the screws. Turn over the display and press it all the way around the perimeter of the iPhone.

Fasten the last two screws near the charging port and install the sim card tray. Turn on the iPhone 8 plus and use the smartphone.
