Galaxy A41 - Replacing the battery

Before you start your repair, we recommend that you test the basic functions of your Galaxy A41 using our checklist. This way you can rule out the possibility that anything has been damaged during the repair.

Switch off your A41 after testing 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.

The Galaxy A41 is opened via its firmly glued plastic back cover. To remove it, you first have to heat the adhesive film with hot air. Use a hot air device such as a heat gun or a regular hair dryer.

1. First, place your phone face down on a soft, clean surface.
2. Move the hot air device evenly over the edge of the back cover.

A rule of thumb: The edge of the back cover should only be heated up to a point where you can still touch it without burning your fingers.

As soon as the edge of the back cover has warmed up sufficiently, you can start to carefully remove it from the middle frame.

Please note that the manufacturer's warranty expires as soon as you open your Galaxy A41.

1. Place a suction cup in the lower part of the back cover and pull it upwards to create a narrow gap between back cover and middle frame.
2. At the same time try to insert a flat, stable tool into the gap to enlarge it. We recommend the iFlex for this.

The iFlex is made of very thin, stable metal and has sharp edges.To avoid scratching the frame of your device, we recommend to use the iFlex only at the beginning and to continue as early as possible with a plastic tool.The easiest way to insert your tool is to place it in one of the two corners of the lower frame of your device.

In the next step the back cover can be completely detached and removed.

1. Remove the back cover from the middle frame piece by piece by moving a plastic tool along the edge of the back cover. For this purpose we use the iPlastix.

1. Insert flat plastic picks at the loosened points of the back cover frame at regular intervals, so that the adhesive cannot rebond.

Warm up the glue with hot air at regular intervals to make it easier to loosen.

1. One the back cover is entirely detached, unfold it carefully and put it aside.

Now start to separate the middle frame from the screen unit. It is firmly hooked and additionally fixed with 16 screws.

1. First, remove the SIM tray from the middle frame by pressing into the small hole next to it with a small, pointed tool.
2. Loosen the screws and keep them in a screw storage box. For this purpose we recommend our magnetic pad.

1. Insert a flat, stable tool between middle frame and screen unit. We use a hard plastic pick for this.

1. Remove the middle frame with the tool by pressing it upward piece by piece.
2. Put the loosened middle frame aside and turn the screen unit back with the display panel facing down.

• Connector

To prevent a short circuit during the repair, you should detach the battery connector from the mainboard as soon as possible.

When detaching the battery connector make sure that you start from the side where there are no small components on the board. This will prevent possible damage.

1. Use a sturdy plastic lever tool to slide under the battery connector and carefully lift it off. We recommend a handy plastic spudger for this purpose.

• Connector

The main board and USB board are connected via a connecting cable. On the side of the USB board, the cable splits into two ends. One end is slightly glued and lies underneath the screen connector.

When detaching the battery connector make sure that you start from the side where there are no small components on the board. This will prevent possible damage.

1. Start by carefully prying off the screen connector.
2. Loosen the glued end of the connector cable with a flat, sturdy tool. We use ESD tweezers for this purpose.
3. You can then detach the two cable connectors from the main and USB board each.
4. Take the disconnected cable out of your device and put it aside.

The battery of the Galaxy A41 is glued to the screen unit on a large surface. To remove it, you have to heat the adhesive with hot air first.

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

Be careful not to bend or otherwise damage the battery when detaching it.

Turn your A41 with the screen upwards and run hot air evenly over the area where the battery is located.

Turn the screen back over and use a sturdy plastic tool to drive under one of the two long edges of the battery to carefully pry it up. We use a battery spudger for this.

Insert a flat plectrum at a loosened spot, so that the glue can't bond again.

Once the battery is slightly loosened, you can run a flat tool, such as the iPlastix, under the battery. Loosen it completely with a motion as if cutting with a knife.

Before you can insert your replacement battery, you have to prepare it.

1. To prevent the new battery from lying unevenly, you should remove larger adhesive residues from the bottom of the screen unit.
2. Then pull off the protective film on the back of the battery.

You can insert the replacement battery at this point.

The battery must be aligned correctly. The battery connector helps you with it.

1. Finally, press the battery into the display unit.

Once the battery is firmly seated in the device again, the connection cable can be attached.

1. First, align the cable correctly. The position of the connectors and the cable label will help you.

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

1. First attach the two cable connectors.
2. Then press the second end of the cable tightly.
3. Finally, reattach the display connector.

Now reconnect the battery.

Never attach connectors with force. Damaging a connector can lead to the failure of an entire component.

1. Carefully press the battery connector on the mainboard, so that you can hear and feel it click into place.

At this point the middle frame can be reattached.

1. Place the middle frame on the display unit and press it firmly, so that you can hear and feel it clicks into place from all sides.

1. Fasten it tight with the 16 Phillips screws.
2. Then insert the SIM tray again.

Before you close your Galaxy A41 for good, we recommend testing the replacement part and other basic functions. This way, you can make sure that your repair was successful. Again, use our checklist for this.

1. Switch on your device.
2. Connect a charging cable to see if the new battery charges.
3. After that, you can check other components for their functionality. To do so, dial the code *#0*# to access the Samsung test menu.

If something does not work properly after the repair, check again if everything is installed and attached correctly.

Once the repair has been successfully completed, you can finally close your Galaxy A41 again.

1. Position the back cover over the display unit.
2. Press it evenly by running your fingers once along the entire edge of the back cover.
3. Finally, heat the back cover again, and weigh it down for half an hour, so that the glue can bond firmly again.
