How to replace your Apple Watch Series 3 battery

Now that we’ve gone over the best battery replacement kits for Apple Watch Series 3, let’s look at how to install the battery into your iWatch 3. Since the watch itself is quite small and fragile, it’s advisable to be very careful while replacing the battery. You’d need to ensure that you’re always following all the steps meticulously. 

All the tools included in this process can be found in the battery replacement kit, itself. 

Step 1: Power off your Apple Watch

Before you start repairing any electronic gadget, it’s crucial to ensure that you turn the power off. Take your watch off the charger and shut it down. Try to ensure that it’s safely turned off before proceeding to the next step. 

Step 2: Opening the Panel

To open the panel, you’d need to apply heat sometimes. For this, you can use a standard hair dryer from your home and slightly warm the face of the watch till it’s just a little hot to touch. When you apply heat, the adhesives underneath the watch’s face will slowly melt, helping you pry off the back without any problem. 

Step 3: Carefully open the panel

You’d want to be extremely careful while removing the panel since the gap is very thin. The tool kit comes with a blade that you can use to slowly inch into the watch to remove the panel.


  • Be careful to protect your finger from the knife or the blade because it might be too sharp. Wearing a glove can protect you. 
  • Do not apply too much pressure because the blade might slip and hurt you. Or, it could also break the glass. 

Step 4: Pry off the screen

Use the thin curved blade to slowly inch into the gap. You’d want to start prying at the short edge of the display. Press firmly into the gap and slowly tilt the blade to remove the display. 

Step 5: Use the curved tool

When you increase the thin gap between the display and the watch, you can use the curved tool to lift the screen off. If you don’t have the curved tool, you can carefully use the blade or the curved knife. 

Step 6: Remove the adhesive

Once you lift the display at about 45 degrees, you’ll notice that there is adhesive around the lining of the watch. This adhesive is what protects the watch’s inner parts from any water damage when it comes in contact with water. You can use the knife or a thin blade to carefully remove all the adhesives. Be careful to not damage any cables while removing the adhesives. 

Step 7: Remove the metal cover

Use the tri-pin screwdriver to remove the main screw that secures the main metal cover plate. This plate needs to be removed carefully. You can use a pair of tweezers to remove the cover plate and open the plate all the way. This way, when you unhinge the flaps, you can close it just about half the way and remove it by lifting it out. 

Step 8: Disconnect the battery

The battery has two main connectors that are usually blue in color. You would want to carefully disconnect the connectors before removing the battery completely. You can lift the connectors straight up and disconnect the battery. Once you do, this you can securely remove the battery. 

Step 9: Replace the battery

You can now open your battery replacement kit that you’ve chosen and insert the battery in. When you insert the battery, you can connect the connectors back in their place.

Step 10: Install the metal cover plate

Install the metal cover plate using the tri-pin screwdriver and screw it back on. Once you have that secured. You can apply adhesive around the lining before sealing the watch. 

Step 11: Seal the Watch completely

When you are done inserting the adhesive along the lining, you can use your thumb and firmly press down on the watch’s display to push it back into place. This is when you’ll hear a click sound on all sides and you’ll know that you have replaced your battery.
