Removing the Screen and Accessing the Battery

Before attempting to replace the battery in your Apple Watch Series 5, it is essential to prepare your workspace and gather the necessary tools. The screen of the Apple Watch is adhered with strong adhesive and contains delicate components, so careful handling is crucial to avoid damage.

Begin by softening the adhesive securing the screen. Use a heat source such as a heat pad or iOpener applied gently around the edges of the watch face for about 1-2 minutes. This will loosen the adhesive and make the screen easier to lift.

Next, use a thin plastic opening tool or a specialized pick to carefully pry around the edge of the screen. Start at the side opposite the Digital Crown and slowly work your way around, taking care not to insert the tool too deeply. The screen is connected to the logic board by a fragile flex cable near the top edge, so do not fully detach the screen yet.

Once a slight gap is created, lift the screen gently, holding it at approximately a 90-degree angle relative to the watch body. Use a plastic spudger to disconnect the battery connector and the display flex cable by lifting the securing brackets and gently prying the connectors free.

Removing the Old Battery

With the screen removed and the battery connector safely disconnected, you can now focus on removing the old battery. The battery is adhered to the rear case with strong adhesive strips.

To safely remove the battery:

  • Locate the battery adhesive pull tabs beneath the battery.
  • Slowly pull the adhesive strips straight out, keeping steady pressure to avoid tearing.
  • If the adhesive strips break or are difficult to remove, apply a small amount of isopropyl alcohol (90% or higher) around the battery edges to soften the glue.
  • Use a plastic card or spudger to gently lift the battery from the case, avoiding any sharp metal tools that could puncture the battery.

Take special care to avoid bending or puncturing the battery, as this can cause hazardous chemical leaks or damage the internal components.

Installing the New Battery

Once the old battery is removed, clean the battery compartment thoroughly with isopropyl alcohol and a lint-free cloth to remove any residual adhesive or debris. This will ensure the new battery adheres properly.

Before placing the new battery, verify its specifications match those of the original battery. Confirm the correct model number and capacity to maintain optimal performance.

Place the new battery into the compartment and align it carefully. Press it firmly to ensure adhesion but do not exert excessive force. Reconnect the battery connector to the logic board, securing the bracket back in place.

Reassembling the Apple Watch

After installing the new battery and reconnecting the display flex cable, carefully position the screen back onto the watch case. The screen adhesive will likely need to be replaced for a secure seal.

Use pre-cut adhesive strips specifically designed for the Apple Watch Series 5 screen or apply a thin layer of waterproof adhesive. Align the screen precisely and press firmly around the edges to ensure proper bonding.

Before final sealing, power on the watch to test the new battery installation and ensure all functions operate correctly, including the touchscreen and digital crown responsiveness.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
