Introduction
Use this guide to replace a worn-out or dead battery in your Galaxy A52.
If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your device. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
You’ll need replacement adhesive to reattach components when reassembling the device. If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.
What you need
-
-
Prepare an iOpener and apply it to the back cover for at least two minutes to loosen the adhesive underneath.
-
-
-
Secure a suction handle to the right edge of the back cover, as close to the edge as possible.
-
Lift the back cover with the suction handle to create a small gap between the back cover and the frame.
-
Insert an opening pick into the gap you created.
-
-
-
Slide the opening pick to the top right corner to slice the adhesive.
-
Leave the opening pick in its place to prevent the adhesive from resealing.
-
-
-
-
Use a Phillips screwdriver to remove the ten 4.4 mm-long screws securing the motherboard cover.
-
-
-
Insert an opening pick underneath the left edge of the motherboard cover.
-
Use the opening pick to pry up the motherboard cover.
-
Remove the motherboard cover.
-
-
-
Use a spudger to disconnect the battery cable by prying the connector straight up from its socket.
-
-
-
Use the flat end of a spudger to pry up and disconnect the interconnect cable from its socket.
-
-
-
Bend the interconnect flex cable towards the charging port in order to get free access to the battery.
-
-
-
Apply a few drops of adhesive remover or high-concentration (90% or higher) isopropyl alcohol into the gap at the left edge of the battery.
-
Tilt the phone in an 45 degree angle to let spread the isopropyl alcohol evenly underneath the battery.
-
Let the adhesive remover penetrate the battery adhesive for at least 1 minute.
-
-
-
For this step, insert a plastic card into the edge with a wider gap between the midframe and the battery so that you have more space for the plastic card and get a better leverage.
-
Carefully slide it underneath the battery to loosen the adhesive.
-
Slide the plastic card underneath and pry up the battery from its recess.
-
If possible, turn on your device and test your repair before installing new adhesive and resealing.
To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
Take your e-waste to an R2 or e-Stewards certified recycler.
