Time Required

Introduction

It is normal for lithium-ion batteries, such as the one found in the Galaxy Tab S3, to sustain damage after each charge cycle and eventually degrade over time. Most tablet batteries are designed to last about 2 to 3 years before becoming too worn out for normal use. If your battery is worn out and no longer holds a charge, you might want to consider replacing it. This guide will show you how to properly remove and replace the battery.

    • To soften the adhesive holding the tablet together, heat up the edges of the glass panel using a heated iOpener on the edge of the device.

    • We used two iOpeners to open up the tablet. The process is doable with a single iOpener, but would take substantially longer. Alternatively, you can use a heat gun to quickly loosen the adhesive.

    • Leave the iOpener on edge for two minutes.

    • Be careful not to burn yourself while handling the hot iOpener. For more information on the iOpener, use the iOpener Instructions Guide.

    There is no reason to remove the screen while replacing a battery.

    • Place a suction cup near edge that you heated up with the iOpener.

    • Press down on the suction cup to create a seal, and pull up with force to create a separation between the display and the midframe.

    • Use an opening tool to split apart the glass panel from the midframe.

    • Be careful to not break the glass when prying from the frame.

    Bonjour, pour moi il est IMPÉRATIF d’opérer l’ouverture par le bord droit comme indiqué sur le tuto car de l’autre coté les nappes du LCD ne sont qu’à 3mm du bord et peuvent etre abimée comme je l’ai fait lors du décollage.

    • As you continue along the edge using the opening tool, use a plastic card to keep the glass separate from the midframe.

    • You can also use multiple opening picks instead of a plastic card.

    For this part I recommend to insert the tools only on top, bottom and right side. Then lift the screen as shown in the pictures in step 4. The left side has the light ribbons for the display too close to the edge and they are really thin. I just broke the four of them in my screen :(

    • As you remove the glass panel, be careful not to tear the ribbon connecting the motherboard to the display.

    • Pull off the glass panel using the suction cup.

    • Carefully disconnect the ribbon connecting the display assembly to the motherboard. You can disconnect this ribbon from either end.

    • Repeat steps 3 through 7 to remove the rear glass panel on the opposite side of the device.

    • Use a Phillips #000 screwdriver to unscrew the five screws securing the battery, and the twenty-two screws surrounding the midframe.

    • The midframe should snap off from the device’s motherboard.

    • Flip the midframe over and pop the battery out, making sure to slide it out from underneath the ribbon cables.

    • The battery should now be removed and detached from the device.

Conclusion

To reassemble your device, follow these instructions in reverse order. If you have removed too much adhesive, you may need to apply more during the reassembly process.

This repair can be done without removing the screen!

hansderaedt -

how? would it be simpler to do it that way?

Ryan McDaniel -

There is no reason to remove the screen. It’s super risky to do it that way. When you take the battery out, just use some alcohol on the sides of the battery to weaken the adhesive and use a suction cup to pull the battery out. No need to push on it from the screen side.

Nick Youngstrom -

What I get for reading a guide before checking comment, TOTALLY unnecessary step in removing screen. LCD cost $220 on ebay….

How many times are you guys heating up the tablet to get it to loose

henry prophete -

Do not remove the screen. Take the back off of the tablet and remove the battery. The screen will crack extremely easily.
