Samsung Galaxy S10 Battery Replacement - Samsung Galaxy S10

Step 1 | Heat the back cover

Unplug and power off your phone before starting.

Apply a preheated iOpener to the right edge of the back cover for two minutes.
Alternative heat sources: use a hair dryer, heat gun, or hot plate, but be cautious not to overheat and damage the display or internal battery.
Refer to the removed back cover image to locate the adhesive areas.

Step 2 | Create an opening gap

Position the phone at a 13mm angle using a support.

Suction cup: Pull with firm pressure while bracing the left edge of the phone.
Opening tool: Insert it into the seam between the back cover and frame.
Opening tool:

Slide it along the seam to loosen the back cover.

Step 3 | Insert an opening pick

Never apply excessive force with the opening pick.

Apply an iOpener to the edge of the phone for two minutes.
Attach a suction cup to the back, near the right edge's center (narrowest adhesive point).
Pull on the suction cup with steady force to create a gap between the cover and frame.

Multiple attempts may be necessary due to tight tolerances and strong adhesive.

Insert an opening pick into the gap created by the suction cup.
If struggling, reheat the edge until just slightly too hot to touch and try again.

Applying isopropyl alcohol (over 90%) can help loosen adhesive in tight spots.

Step 4 | Slice through the adhesive

Cracking the back cover can occur if the corner adhesives are sliced without heat.

Slide the opening pick along the phone's edge, cutting through the adhesive.
Heat is required before slicing corner adhesives to prevent damage.
Leave a pick in the seam to keep the adhesive from re-sealing.

Step 5

Apply a heated iOpener to the bottom edge of the phone for 2 minutes.

Insert an opening pick into the right edge near the bottom right corner and carefully slide it around the corner.
Continue cutting along the bottom edge and around the bottom left corner, re-applying heat if necessary to aid the process.

If the adhesive starts to re-seal, ensure an opening pick is still in the seam.

Step 6

Continuously heat and slice along the remaining phone edges.

Apply extra heat to the corners before cutting.

Step 7

Insert an opening pick into one edge of the phone to begin separating the back cover.

Lift the back cover slowly using the pick.
Slice any remaining adhesive with additional picks.

Power on your phone and test all functions before sealing the back cover.

Power down your phone completely before proceeding with reassembly.

Follow this guide for reinstalling the back cover, camera bezel, and adhesive.

If desired, you can skip replacing the adhesive. Remove large chunks of adhesive that may interfere with a flush fit.

Apply heat and pressure to secure the back cover after installation.

Step 8 | Remove the midframe

Remove the eight 4 mm Phillips screws that secure the top midframe.

Step 9

Be careful when prying the midframe as it may be damaged easily.

Locate the plastic clips along the edge of the midframe.
Insert a spudger into the notch near the volume up button on the right edge.
Pry upwards to loosen the midframe from the phone.

Step 10

Remove the midframe from the top corners of the phone.

If the top midframe is stuck to the lower midframe, slowly peel it off at the bottom right corner.
To reinstall, align the top edge of the midframe and lay it down on the phone.
Apply gentle pressure along the perimeter with fingers to snap the clips back into place.

Step 11 | Disconnect the battery

Insert the flat end of a spudger under the battery connector attached to the motherboard below the rear-facing camera.

Pry upwards with the spudger to disconnect the connector from its socket.

Be careful not to dislodge surrounding small surface-mounted components when disconnecting connectors.

Push the battery's flex cable away gently to prevent accidental contact.

Step 12 | Battery

Be cautious of adhesive around the battery — risk of damaging surrounding components.

Locate marked areas under the battery for reference:

Frame where the battery is secured with strong adhesive.
Display cutout area, be gentle to avoid damaging display components.

Step 13

Avoid direct heat on the battery to prevent risk of fire.

Apply 1-2 drops of adhesive remover or isopropyl alcohol (90% concentration or less) to each battery corner.
Wait 1 minute for the liquid to weaken the adhesive.

Excess liquid can seep into cutouts and damage surrounding components. Apply only a few drops at a time.

As an alternative, heat an iOpener and apply it to the right side of the front for 2 minutes or until the battery is warm to the touch.

Step 14

Insert the corner of an opening card into the crevice between the battery and the bottom midframe.

Pry the battery out using firm, constant pressure.

If it does not budge, apply more adhesive remover or isopropyl alcohol and repeat the process.
Alternately, try applying heat with an iOpener.

Do not use metal tools to pry the battery out — risk of damage or injury.

Step 15

Never reuse removed batteries — potential safety hazard.

Remove the old battery.
Wait ten minutes for liquids to evaporate if isopropyl alcohol or adhesive remover was used.
Install a new battery and follow installation guide.
