Introduction

This guide shows how to apply custom-cut battery adhesive when you replace a battery.

The guide uses a Samsung Galaxy phone for demonstration purposes. If you're following this guide for other phones, the adhesives will look slightly different, but the procedure will be the same.

If you are using double-sided tape instead, use this guide as a general guideline for where to apply the tape.

    • Remove any remaining adhesive from the phone frame, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • Before you begin, figure out how the pre-cut adhesive strip should be oriented and which surface to attach it to.

    • If your pre-cut adhesive has pull tabs facing the center hole, the adhesive will attach to the phone's battery well first.

    • If your pre-cut adhesive strip has pull tabs on the outer perimeter, the adhesive will attach to the battery first.

    • Peel the clear plastic liner off of the pre-cut adhesive strip, exposing the adhesive.

    • Line up a long edge of the adhesive with the proper surface, as determined above.

    • Carefully set the adhesive down on the surface.

    • The adhesive is very sticky, so you have only one chance to align it.

    Test the battery before doing anything with adhesive. Also, the adhesive is entirely optional - it is NOT necessary for the phone to function well, as the battery is a tight enough fit not to wiggle any connectors loose.

    When I tried this, the adhesive stuck to the backing better than it did to the phone frame, and became tangled. I don’t see any way I could have prevented that.

    • Once the adhesive is aligned, use your fingers to press the adhesive into place.

    • When you are ready to stick the battery onto the frame, carefully peel away the blue plastic liner to expose the adhesive.

    • Set the battery lightly in place.

    • Plug in the battery connector temporarily to ensure that the cable reaches the socket.

    • Press the battery perimeter firmly with your fingers to help the adhesive bond.

    • Disconnect the battery before resuming re-assembly.

    the plug is actually not so easy to mount. luckily, I tried before removing the blue plastic liners. I ended up plugging the battery in before glueing it in place, just to be sure I could connect it at all, which worked fine for me.

    also, I recommend checking if the battery loads and whether the phone still works, before glueing the back cover on the phone

    Based on Michael’s comment above, I wanted to test to see how hard it was to electrically connect the battery. I am glad I did, as it would have been difficult to connect after the battery was mounted with adhesive (depending on where the battery sat within its compartment).

    My steps:

    1. Connect the battery electrically

    2. Cut the adhesive into a couple 1” strips, attach them to the back of the battery. (I tried to attach the whole adhesive to the battery and then pull the backing off, but it became kind of a hassle and didnt work too smoothly. I figured a couple strips would be adequate and it was)

    3. Press the battery into its compartment.

    Bill Slobotski -

    The directions mention that the adhesive can be repositioned if it’s not aligned correctly. This was definitely not the case for me. Once I put the adhesive onto the battery, I noticed it was slightly off, so I tried to lift it up to reposition it, and it ended up stretching and then getting crumpled. Not too big a deal for the battery, but could be an issue for the case.

    Hi Dennis,

    Thanks for the comment! I’ll adjust the instructions to include your findings.

    Arthur Shi -

    Replaced battery. Have always had success doing that on my Samsung phones, but this time when set to charge it flashes for about 5 seconds with the percentage sign not even zero percentage sign, and then it goes off for three seconds, on for 5 seconds off for 3 seconds, on for 5 seconds off for 3 seconds. I feel like it's trying to tell me something but what? no problem opening the phone back up again but hesitant to do so as obviously I was not successful with battery replacement. Any suggestions?

    Place the battery by aligning the top to the top of the well, then put it down lightly.

    The battery (that I received) is slightly smaller than the well. Optionally, as in the 1st comments, first plug in the connector, test it with usb connect and powering on. Then usb disconnect and power off. You can leave the battery connected while placing carefully to ensure connectability.

    I placed the battery aligning the bottom side first, since that side was partly no adhesive, discovering a small gap between the top side of the battery and the well. The connector could not reach the socket. Luckily, the battery was not yet adhered that much and I could lift the battery again.

    Eduard -

    For me the battery connector could not be aligned properly once the battery was positioned in place due to torsion on the battery cable. You must first position the connector so it is square with the connector in the phone, press it in, and only THEN move the battery into its final resting place. When I did it that way it was easy. With the battery already in place (but not yet fully stuck), it was impossible.

Fantastic job on the instructions ! I only wish I was able to find a solution, for removing the original glue from the back cover.

That is all I have left to do, and I have been unsuccessful for 6 to 8 hours of trying to find a way to get it off.

Lee Jones -

Hey Lee,

Your best chance is using high concentration (over 90%) isopropyl alcohol . If you can’t get the surface completely clean, that’s alright. Just try to get all large adhesive residue off, so that the battery and new adhesive will lie flat in the battery well.

Arthur Shi -

I accidentally rubbed off some of the black paste thing under the battery when cleaning it for the new battery adhesive strip. Should I be worried??

Henry Dang -

Hi Henry,

The black paste is possibly the graphite pad stuck onto the back of the display, which channels heat from the phone to dissipate through the display. There shouldn’t be any damage to your phone!

Arthur Shi -

Hi Arthur,

A big respect & thank you for the instruction to replace the battery. I couldn't be more happier because I did it myself thanks to you & ifixit team. It only took 30 minutes from start to finish. Just waiting on the back glass to arrive other wise excellent job on your side and awesome job to ifixit. I will have to buy higher concentration of isopropyl to wipe those big adhesive before I put the glass.

I’m glad to hear of your success! Keep fixing things!

Arthur Shi -

The Old Battery Connector SNAPS into place. but not the new battery i was sent. Could there be different Connectors??

Ted Fackelman -

Hey Ted,

This is a general guide for battery adhesive, so I can’t tell which phone you’re working on. Which phone are you replacing the battery for?

Arthur Shi -

91% percent isopropyl alcohol removes the residue very well. It is available at the local drug store about 2 dollars for a quart.

michael kotarba -

Greeting Arthur,

Thank you for the excellent, detailed instructions. I was able to replace my OEM battery without any problems. I do have a question related to charging the new battery. Your direction is: 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%. The instructions that IFIXIT sent with the kit was to allow it to run down to 10% then charge it to 100%. Is there a big difference here or are both methods okay?

Robert Fitzmaurice -

Hi Robert,

I’m glad you’re able to replace the battery! The proper way to calibrate the battery is to allow the device to run until it shuts off. This allows the battery management hardware to have a point of reference on what 0% is, and potentially reset any counter errors. For more details, check out this page.

Arthur Shi -

oops, forgot to clean off the old adhesive. is that going to be an issue? I already stuck on the new one...

Emily Lynn -

Hi Emily,

For the most part it should be fine, as long as there weren’t large uneven chunks of adhesive.

I am unable to find adhesive tape for Galaxy s8 Active. Do you have a suggestion on what comparable tape might work on the s8 Active?

gboyles -

This is only half the work. The pictures don't match at all. Now that the glue strip is in, now what. What are these other strips for?

Jon Christensen -

I was directed here from the Samsung S6 battery removal. The images for the frame of this phone do not match the S6 that I have. Also, the parts and adhesives referenced here are not for the S6 either. This parts list show S7, S8, and S9 parts, implying this guide is NOT for S6 phones.

Also, there was no replacement adhesive for the front part that fits the frame in the kit sold from ifixit. The adhesive for the battery and back part seemed to be in the kit.

Samsung Galaxy S6 Battery Replacement

Micheal -

Hi Michael!
You're right—this is a general battery adhesive guide for Samsung phones. Your S6 will look differently from the images, but the procedure should be the same. I'll update the intro to reflect this.

Arthur Shi -

Thank you, Arthur. I also wasn't careful in reading, I assumed it would cover replacing the midframe also.

The battery guide didn't provide a guide for that procedure, and no adhesive replacement was issued with the repair kit.

I appreciate it!
