If your LG G8 ThinQ is having trouble holding a charge or staying turned on, use this guide to replace the battery. The battery is the main source of life for the device, and therefore can cause several issues if damaged. Refer to the troubleshooting page to decide if this is the repair you need.
Before disassembling your device, discharge the battery below 25%.
Swollen batteries can be very dangerous, so wear eye protection and exercise caution.
This phone uses a strong adhesive on the battery and back panel; iFixit’s adhesive remover or high concentration (90% or higher) of isopropyl alcohol can be used to make the process easier.
Adhesive can be replaced to closer replicate factory fit and finish.

You don't use any heat to remove the back glass panel? Just suction cup and prying?
Yep need heat to remove the back. Glass shattered on mine. Ifixit needs to fix this guide.
Success! I documented the process using ifixit tools on https://waynedavis.com
