Samsung Galaxy A3 (2017) Battery Replacement

Power off your phone before disassembly to avoid any potential risks.

• Apply an iOpener to loosen the back cover adhesive for at least two minutes.
• You may need to repeat this step multiple times during removal.

Alternatively, use a heat source like a hair dryer, heat gun, or hot plate – but be cautious not to overheat, as the AMOLED display and internal battery are sensitive to heat damage.

Use a small suction handle to create a gap at the bottom end of the Galaxy A3.

• Insert an opening pick and slide the tip to the bottom left corner to cut the adhesive.
• Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.

Insert another opening pick, sliding it towards the bottom left side of the phone to continue cutting the adhesive.

Use an opening pick to score all sides of the phone.

Leave one opening pick in each corner to prevent resealing.

• Reuse the iOpener if adhesive becomes hard to cut.
• The back cover is under tension; be cautious not to break it until adhesive is loose enough.
• Insert an opening pick on the right side, flip it sideways for a secure grip.

Remove the back cover from the phone.

• Preparation for new adhesive: Remove any remaining adhesive from the back cover and the frame.
• Clean the areas with isopropyl alcohol and a lint-free cloth.

Remove five Phillips #00 screws holding the motherboard covers.

• Set the screws aside for later use.

Remove the upper part of the motherboard cover using a pair of tweezers.

Be careful not to break the small plastic clamps securing the cover.

• Use a pair of tweezers to carefully lift the motherboard cover, which includes the loudspeaker and NFC antenna.
• Once lifted, completely remove the motherboard cover.

Disconnect the battery flex connector using the flat end of a spudger.

Apply the iOpener to loosen the adhesive under the battery.

Insert the flat end of a spudger into the bottom right gap of the battery and gently pry it up.

• Move the spudger to the bottom left corner and continue prying it up slightly.
• Only insert the spudger as far as the notch on its flat end.

Caution: Prying in areas other than yellow-marked rim may damage the display.

• Insert the spudger under the battery's recess, targeting the sides.
• Pry carefully to cut remaining adhesive until the battery is loose.

Disconnect and remove the battery.
