Galaxy A52 - Replacing the battery

We recommend that you use our checklist to test basic functions of your phone before the repair. This way you can rule out the possibility that anything has been damaged during the repair. Afterwards you have to switch off your A52 to avoid a potential short circuit.

1. To do this, first press and hold the side and volume down key simultaneously for a few seconds.
2. Tap on "Switch off" in the displayed menu.
3. Your phone will now shut down completely within a few seconds.

Once you open your device its specified IP68 certification will expire.

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

1. Attach a suction cup to the lower edge of the back cover and pull it upward to create a narrow gap. At the same time, insert the iFlex between the screen unit and the back cover.

To avoid damaging the edge of the case with the sharp edges of the iFlex, you should switch to a plastic tool like the iPlastix as soon as possible.

Be extra careful when loosening around the camera module, so you don't damage it with your tool.

1. Drive the tool completely around the edge of the back cover to loosen it piece by piece. Heat the adhesive again in between.
2. Slide flat picks under the back cover at regular intervals, so that the glue cannot bond again.

• 10 × 4.4 mm Phillips

We recommend you to use a screw storage during the repair. This way you keep track of screws and small parts and don't lose anything. For example, you can use our high-quality magnetic pad.

1. Remove the 10 Phillips screws from the cover above the motherboard.
2. Then place them on the magnetic pad.

A notch in the board cover shows you where to best place your tool.

1. Use a prying tool, such as a spudger, to pry the unscrewed cover out of the case.
2. Then, put it aside.

• Connector

Always detach the battery connector as soon as possible to avoid a potential short circuit.

When separating connectors, always start from the side where there are no small components on the motherboard. This way you avoid potential damage.

1. Carefully pry the battery connector from the motherboard with a plastic spudger.

• 6 × 4.4 mm Phillips

1. Loosen the six Phillips screws that fix the speaker module in the case.
2. Then, place them on the magnetic pad.

A notch in the speaker modul shows you where to best place your tool.

1. Pry the unscrewed speaker out of the case and put it aside.

• Connector

The connecting cable between the USB and motherboard runs above the battery. It is attached with two connectors on the USB and one connector on the motherboard.

1. Use a spudger to separate the three connectors one after the other.
2. Take the detached cable out of the device and put it aside.

The battery of the A52 is heavily glued into the display unit. In order to make it easier to remove, you should therefore heat it previously.

Never heat the sensitive battery directly, but only from the screen side.

1. Heat the battery by running a hot air gun evenly over the corresponding opposite spot on the screen.

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

1. Use a lever tool, such as the battery spudger, on one of the two long edges of the battery and carefully lift it up a bit.
2. Insert the flat iPlastix at the lifted edge and slide it under the battery bit by bit to completely detach it from the bottom of the screen unit.
3. Remove the detached battery from the device.

1. If necessary, bend the battery connector, so that it can be pressed well onto the slot on the motherboard.
2. Remove the protective film from the back of the battery.

Remove thicker adhesive residues from the case bottom. These can cause the battery to sit unstable in the guide. In the worst case, this can cause the battery to inflate.

1. Place the battery in its guide in the screen unit and press it firmly.

• Connector

Never attach connectors by force. Damage can lead to the failure of an entire component.

1. Align the connecting cable above the battery. Its labeling will help you do this.
2. Reattach it by gently pressing its three connectors onto the USB- and motherboard.

• 6 × 4.4 mm Phillips

To ensure that the speaker sits level, the plastic lugs on the edge of the module must blend into the case frame. For this, it is best to set it at a slight angle.

1. Insert the speaker.
2. Subsequently, fix it with six Phillips screws.

• Connector

Always connect the battery last to avoid a potential short circuit.

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

• 10 × 4.4 mm Phillips

To ensure that the board cover sits level, the plastic lugs on the edge of the cover must blend into the case frame. For this, it is best to set it at a slight angle.

1. Insert the cover.
2. Subsequently, fix it with ten Phillips screws.

Before you glue your A52 again, you should test it for functionality at this point.

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

1. Connect your Galaxy A52 to the mains in order to check the functionality of the replacement battery.
2. Also control the screen functions.
3. Call up the Samsung test menu via *#0*# in the phone app to test additional components. As an alternative use our checklist.

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

1. Heat the adhesive frame with hot air to make it easier to remove from the inside of the back cover.
2. Pull it off bit by bit with a pair of tweezers.

Before applying the new adhesive frame, align it with the back cover. Use its corners and recesses for orientation.

1. Peel off the carrier film from the bottom of the adhesive frame and press it onto the edge of the back cover. A spudger can help you with this.
2. Now carefully peel off the two remaining protective films from the top of the adhesive frame one after the other.

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 Samsung Galaxy A52 after the repair by pressing the back cover back onto the screen unit.
