Are you looking to repair your Fitbit Charge 3 or simply curious about its inner workings? Knowing how to disassemble your Fitbit Charge 3 can be helpful for various reasons, from replacing a broken strap to cleaning dust and debris from the device. This guide will take you through a step-by-step process on how to safely disassemble your Fitbit Charge 3.

Essential Tools and Preparation

Before you begin, ensure you have the following tools readily available:

• Small Phillips head screwdriver: This is crucial for removing the screws holding the device together.
• Spudger: A spudger is a plastic tool used to pry open the device without scratching the surface.
• Tweezers: Tweezers are handy for handling small parts and removing adhesive.
• Anti-static mat: This helps prevent static discharge that could damage the electronics within the device.
• Clean workspace: A clean and well-lit workspace is essential for working with small components.

Important Note: Disassembling your Fitbit Charge 3 will void the warranty. Proceed at your own risk.

Step 1: Removing the Strap

1. Detach the strap: Gently pull the strap from the device’s housing. You might need to use a small tool like a spudger to help release the strap from the clips.
2. Remove the strap connector: There are two small screws holding the strap connector to the device. Use your Phillips head screwdriver to remove these screws.

Step 2: Opening the Device

1. Locate the seam: The Fitbit Charge 3 has a seam running around the perimeter of the device. This is where you will apply pressure to pry it open.
2. Apply pressure: Use your spudger to carefully pry open the seam. Start at one end of the device and work your way around. Be gentle and avoid excessive force.
3. Separate the halves: Once you have pried open the seam, gently separate the two halves of the device. Be mindful of any cables or connectors that may be attached to the motherboard.

Step 3: Disconnecting Components

1. Locate the battery connector: The battery connector is usually located near the bottom of the device.
2. Disconnect the battery: Use your spudger to gently pry up the battery connector.
3. Disconnect other components: There may be other components connected to the motherboard, such as the heart rate sensor or the display. Carefully disconnect these components using your spudger.

Step 4: Removing the Motherboard

1. Remove screws: There are several screws holding the motherboard to the device’s frame. Use your Phillips head screwdriver to remove these screws.
2. Lift the motherboard: Once all the screws are removed, gently lift the motherboard from the device. Be careful not to damage any components.

Step 5: Disassembling the Display

1. Remove the display connector: Locate the connector that connects the display to the motherboard. Carefully disconnect it using your spudger.
2. Remove the display: The display is held in place by adhesive. Use a heat gun or hairdryer to gently warm the adhesive. Once the adhesive is softened, you can carefully pry the display off the device using your spudger.

Step 6: Reassembly

1. Reverse the disassembly process: To reassemble your Fitbit Charge 3, simply reverse the steps you took to disassemble it. Make sure to reconnect all the components and tighten all the screws.
2. Test the device: Once the device is reassembled, test it to ensure everything is working correctly.
