Introduction

This guide will show you how to replace the battery in the LG V30 (and V30+) smartphone. If your battery is draining too quickly or has stopped charging fully, replacing the battery should alleviate your issues.

This guide involves removing the back cover of your device, so you will need replacement adhesive to reattach the back cover to the phone. This guide also involves removing the battery of your device, which is attached to the inside of the phone using adhesive. You will need replacement adhesive to reattach the battery to the inside of the phone.

Before disassembling your device, be sure the battery is charged below 25%. If accidentally punctured or damaged, the battery can catch fire and/or explode; if discharged below 25%, the chances of fire/explosion are decreased.

    • Using a heat gun, hair dryer, or hot plate will make the metal frame rather hot to the touch, so handle it with care.

Do you have to put the adhesive for the battery?

Suction cups on both sides, heatgun on the back pannel, then lift. Much easier. And you don't have to worry about breaking the back panel.

Why can’t the idiots at LG, or indeed any other company, make a phone with an MQA capable DAC, and a replaceable battery?

tonywinter - Reply

it is not about idiocy. When you do not conform to a set battery shape you can configure the insides of a phone for more performance and features. That being said the LG V30 does have a standard battery shape. So in this case it is a desire to create built in obsolescence. After all it is believed in the western world cell phone sales are flat.
