Galaxy A53 - Replacing the battery

Use our checklist to test the basic functions of your Galaxy A53 5G before repairing. This way you can check afterwards if your repair was successful.

1. Press and hold the side and volume down button simultaneously for a few seconds.
2. Tap on Power off in the displayed menu.

1. Heat the edge of the back cover by running the hot air device evenly over it.

As an alternative to the suction cup, we can recommend the iSclack, which requires less force to lift up the back cover.

The iFlex can be inserted particularly well between the back cover and the screen unit due to its sharp edges.

1. Attach a suction cup to the lower edge of the back cover and pull it upwards to create a narrow gap.
2. At the same time, insert a flat tool into the gap between the back cover and the screen unit.

In order to prevent the glue of the back cover from bonding again, we recommend sliding flat plastic picks under the back cover at regular intervals.

To avoid damaging the camera module, you should not insert your tool too far. At this point, the hard plastic pick is therefore particularly suitable.

1. Drive your tool completely around the edge of the back cover to loosen it piece by piece.
2. Put the detached back cover aside.

• 8 × 3.8 mm Phillips

We recommend using a screw storage, such as our magnetic pad, to keep all disassembled parts and screws safe and organized.

1. Remove the eight Phillips screws from the board cover and place them in the screw storage.

• Connector

To avoid a potential short circuit during the repair, you should always disconnect the battery as soon as possible.

1. Carefully detach the orange battery connector with a spudger from the motherboard.

• 7 × 3.8 mm Phillips

1. Loosen the seven Phillips screws that hold the speaker in place.
2. Carefully lever the speaker out of its guide with a spudger and set it aside.

• Connector

The connecting cable connects the USB and motherboard. It has a total of three connectors. One of them is attached to the screen cable.

1. Carefully separate the three connectors of the connecting cable with a spudger.
2. Put the detached cable aside.

The battery of the A53 5G is heavily glued. In order to loosen it safely, you need to heat up the glue in advance.

Never heat the heat-sensitive battery directly, but only from the edge of the case or the side of the screen glass.

1. Heat the battery by running a hot air gun evenly over the case edge and the corresponding opposite area on the screen.

The battery can be loosened particularly well if you move the iPlastix under the battery with a cutting motion.

1. Place a battery spudger on the lower edge of the battery and carefully lift it upwards.
2. Remove the detached battery from the device.
3. Insert the flat iPlastix under the battery at the lifted edge and detach the battery bit by bit from the bottom of the screen unit.

1. Remove the protective films from the front and back of the battery.
2. If necessary, bend the battery connector, so that it can be pressed well onto the slot on the motherboard.
3. Put the replacement battery back into its guide and press it firmly.

• Connector

The cable labeling will help you align it in the device.

1. Align the connecting cable and attach its three connectors to the USB and motherboard.

• 7 × 3.8 mm Phillips

Make sure that the speaker sits level all over. Its plastic lugs must fit into the edge of the case.

1. Put the speaker back in its original position.
2. Screw it in place with the seven Phillips screws.

• Connector

Always connect the battery as late as possible to avoid a potential short circuit.

1. Reconnect the battery by gently pressing its connector onto the motherboard.

We recommend testing the new battery and other basic functions at this point. Again, use our checklist for this and the internal Samsung test menu, which you call up via the code *#0*#.

If something doesn't work properly, double-check that everything is installed and connected correctly.

1. Connect your Galaxy to the mains in order to see if the replacement battery is charging.

If the adhesive frame is still in good condition, you do not need to install a new one. However, if it has defects or no longer sticks properly, we recommend that you use a new adhesive frame.

1. Align the new adhesive frame with the back cover. The cutouts in the film will help you.
2. Peel off the carrier film from the bottom of the adhesive frame and press it onto the edge of the back cover.
3. Now carefully peel off the remaining protective films from the top of the adhesive frame.

We recommend that you run hot air over the edge of the back cover again, so that the glue bonds properly. You can also weigh down your device with books for a few minutes.

1. Close your Galaxy A53 after the repair by pressing the back cover back onto the screen unit.
