Samsung Galaxy A5 (2017) Battery Replacement

Opening the Samsung Galaxy A5 (2017) will damage its waterproof sealing.

If you do not replace the adhesive seals, your phone's water-protection will be compromised.

Do not heat a swollen battery – it can be very dangerous.

You'll need replacement adhesive to reattach the battery and back cover during reassembly.

Power off your phone before disassembling.

Apply an iOpener for at least two minutes to loosen the adhesive beneath the back cover.
You may need to repeat this process several times during removal.
If necessary, use a heat source like a hair dryer or heat gun to aid in adhesion release.

Avoid overheating, as the AMOLED display and internal battery are sensitive to excessive heat.

Insert an opening pick at the bottom end of your phone.

If it doesn't fit, use a suction handle to create a small gap between the back cover and frame.
Slide the opening pick's tip to the bottom left corner, cutting the adhesive with it.
Leave the opening pick in place to prevent resealing.
Insert another opening pick and cut the adhesive on the phone's left side.

Insert an opening pick around the entire phone, ensuring one is in each corner to prevent resealing.

Be cautious: the back cover may break under tension if adhesive remains too tight.

If necessary, reuse an iOpener to soften stubborn adhesives.
Insert a second opening pick on the right side and flip it sideways for better grip.

Remove the back cover from the phone.

Remove the eight Phillips #00 screws securing the motherboard cover.

Lift the motherboard cover from both upper corners using a pair of tweezers.

Release the cover, along with the NFC antenna and loudspeaker, from its clamps.

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

Apply heat from a iOpener to soften the adhesive underneath the battery.

Insert the flat end of a spudger into the gap at the bottom end of the battery.

Pry up the bottom right corner, then move the spudger to the bottom left corner and pry it up as well.
Insert the spudger no further than the notch on its flat end.

Be careful not to damage surrounding components.

Only pry in areas marked with yellow paint.

Use a spudger to loosen the remaining adhesive under the battery on its side edges.

Be careful not to pry near the display center, as this is the back side and may be damaged.

Disconnect and remove the battery.
