LG G5 Troubleshooting
Battery Dies Quickly
Battery loses charge a lot quicker during use.
Dirty Battery Terminals
If the battery dies quickly then maybe the terminals are dirty. Cleaning battery terminals is an easy fix with the LG G5. The G5 has a removable battery, so you would want to refer to the battery replacement guide to remove the lower and back half of the phone. Once disassembled you will need to wipe the battery terminals with a soft cloth, similar to one you would use for glasses.
Exposure to Excessive Heat
If the battery dies quickly it could be damaged due to exposure to excessive heat. Excessive heat causes the battery to not function at its highest potential. Heat causes the battery to age, thus shortening the battery's lifespan, so try to keep your LG G5 within the recommended operating temperatures. To replace the battery you would want to refer to the battery replacement guide to remove the lower and back half of the phone. Once disassembled you will simply remove the battery, and insert a new battery which should have your phone working like new.
Notification LED Does Not Turn On
Notification LED (top-middle green light) does not appear when some text messages or app notifications are downloaded.
LED Settings Are Not Set Up Correctly
This LED light problem is just a settings issue. YAY! To fix the problem, simply press the home button then Tools > Settings > Sound > Notification LED. Then change the LED toggle to “on” if it is off. Check to make sure the LED is set to go off for the notifications you want; these toggles should appear on that same page.
Bluetooth Connection Does Not Work
Difficulty connecting or maintaining a connection between the LG G5 and another Bluetooth device.
Your Bluetooth may not be working due to an interference between LG’s Smart settings and the Bluetooth connection. To fix the problem, open the Setting application > General > Smart settings. Then, disable any settings that toggle Bluetooth such as the “When at home” setting.
Faulty Network Profiles
Another possible issue with Bluetooth connectivity is a faulty network profile. To reset your network profiles go to Setting > General > Backup & Reset > Network Setting > Reset. After you have reset the network profiles try again to connect to your target device. Note: This will also reset any saved Wifi passwords.
Backlight Bleeds Through Edges of Screen
Bright light appears around corners/edges of the screen. Picture distorted when screen is pushed.
Backlight bleeding is most likely a manufacturing error and can only be fixed by replacing the screen or replacing the entire phone (Contact your service provider or retailer). If you are not sure that backlight bleed is the issue, you can test it with the Backlight Bleed Test App.
Auxiliary Cord Plug-in Is Faulty
Auxiliary port (port on top right of phone) does not read audio properly or consistently. It may make a static "hissing" noise.
A broken audio cable is the most likely cause for auxiliary port inconsistency. Audio cables get bent and damaged all the time and the easiest solution is to simply replace them. It is much easier to double check whether the cable is faulty than to take apart the phone.
Faulty Auxiliary Port
The static/hissing may be caused by a broken auxiliary port itself. Inside the port, there are spring loaded connectors that are probably not making proper contact with the plug. The auxiliary port itself can be replaced if necessary.
