LG K4 Battery Replacement

Replacing the battery of your LG K4 is essential after a certain period as it degrades over time.

This process may be more complicated in newer phones, but for this device, it is relatively straightforward and does not require special skills.
Follow this guide to learn the correct steps for replacing your LG K4's battery safely and effectively.

Step 1 | Battery

Turn off the phone to avoid electrical issues and potential data loss.

Step 2

Use a plastic opener or your fingers to pry open the phone's back cover.

Gently press one end of the tool into the small indentation on the side.
Pull carefully to avoid damaging the case.

Avoid using excessive force, which can crack the casing.

Step 3

Remove the back cover.
Grab the battery's lower edge and remove it from the phone, leaving it aside.

Step 4

Insert the new battery, aligning it with the four-pin connector.

Verify polarity before securing the battery, noting the positions of the positive (+) and negative (-) terminals.

Step 5

Leaving gaps between the phone and back cover can allow debris entry.

Ensure the headphone jack, charging port, and volume buttons are flush with the back cover.
Close the back cover tightly, leaving no gaps for dust or water to enter.

Step 6

Turn on your phone and check if the battery charges.

If the phone does not turn on, give it sufficient charging time before attempting further steps.

If still non-functional after sufficient charging, the battery may need to be replaced.
