All batteries degrade over time, and eventually do not hold the same amount of charge that they did when they were new. You can measure how much energy your battery currently holds at 100% now versus how much it originally held with an app called Accubattery.
The app will need to run for a couple days before recording enough information to give you an accurate reading.
It will also tell you about good habits to use when charging your Android phone to reduce battery degradation.
LG Battery Replacement
If your phone doesn't hold a charge like it used to, randomly shuts down, or won't power on without being plugged into a charger, you may have a battery issue.
Battery replacements for newer LG phones are typically $55-85 for parts and labor, depending on the exact model.
Some phones have removable batteries, which can be replaced by the customer, and don't include a labor charge, like those mentioned above.
LG Charging Ports
If your phone still powers on but will no longer charge, or if your cables work on other phones but not yours, you likely need a new charging port.
LG charging ports are typically $55-85.
It is recommended to bring in your charger and cables for testing and inspection if you have a charge port issue. A worn or damaged charging port can damage cables, which can then damage other charging ports, and vice-versa.
