Tools needed: Screwdriver, tweezers, crowbar, and guitar pick
Please press the button on the left side of the phone, slide it to the left, and remove the battery module.
Removing the battery is much easier than in other phones on the market.
Separate the bottom module from the battery. The LG G5 comes with a 2700mAh battery.
On the bottom module, we can find the battery module clip, main antenna shrapnel, deputy board connector socket, main antenna contacts, and deputy board contacts.
Now remove the SIM card tray.
SIM1: Nano-SIM
SIM2: Nano-SIM & TF-card
The SIM card tray features a T-shaped design to prevent reverse insertion, thereby avoiding damage to the SIM/SD card contacts and ensuring the card can be easily removed.
Remove the two screws.
Insert a guitar pick between the back cover and chassis, and slide the pick until the back cover is removed.
There are six screws securing the motherboard to the chassis.
It is worth noting that the back cover features a spring-loaded mechanical mechanism designed to secure the battery.
Disconnect the display cable from the motherboard.
Remove the six screws that secure the motherboard. And then take out the motherboard.

The LG G5 features dual rear cameras. Unlike the Huawei P9, it does not use structural components to fix the two lenses together. In principle, the G5’s rear cameras serve different functions: a wide-angle lens and a standard optical zoom lens.

What are the two connections from the logic board to the battery module? The small one broke on my phone, but I haven’t noticed a difference in functionality yet.
I had the same issue. Now I’m having signal problems. Did you notice something?
Yes. The battery module houses the antennas, and that connector is what bridges them to the logic board. I had to replace my phone. You could replace the logic board if you find it cheaper. Or maybe have someone solder it together, though I’m not sure that’s possible.
My phone cannot produce recorded sound.
What could be the problem?
What is the main problem if the LG G5 has an invalid battery and then shuts down? Do I need to change the back panel or what? Thank you for answering. I hope you notice this.
