Follow this guide to remove the lithium-ion battery inside the Pixel 3a.

If your battery is swollen, take appropriate precautions. For your safety, discharge your battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.

The Pixel 3a’s unreinforced display panel is fragile. If you are reusing the screen, be sure to pay special attention to the warnings in the opening procedure.

  1. Take note of the two seams on the phone: Screen seam: This seam separates the screen from the rest of the phone. This is where you should pry. Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.
    • Take note of the two seams on the phone:

    • Screen seam: This seam separates the screen from the rest of the phone. This is where you should pry.

    • Frame seam: This is where the plastic frame meets the back cover. It is held in place by screws. Do not pry at this seam.

    • Before you begin prying, note the following areas on the screen:

    • Screen flex cable: Do not pry deeper than instructed, or you risk damaging this cable.

    • Adhesive perimeter: Prying beyond the narrow perimeter without angling the pick will damage the display panel.

    Power is off, but does the battery need to be disconnect to safely do this replacement?

  2. Heat an iOpener and apply it to the right edge of the display for a minute.
    • Heat an iOpener and apply it to the right edge of the display for a minute.

    • You can choose to skip this step since the Pixel 3a's screen adhesive is not very strong. Heating it, however, will decrease the chance of cracking the screen.

    I used a washcloth soaked with hot water and sealed in a plastic bag instead of the iOpener for this step, and it worked great.

  4. This step shows how to insert the pick without damaging the OLED panel. Do this before you slice either long edges of the phone. With the pick 1 mm in the gap, pivot the pick upwards to a steep angle. At this angle, carefully push the pick into the gap about 1/4" (6 mm). The pick should slide in below the OLED panel.

    If you don’t have picks, you can also use the corner of an old gift card, though it may be necessary to shave it a bit thinner with a knife so it fits the gap better.

    Don’t make my mistake and read ahead. 6mm may be too close for comfort! 8mm is definitely too far and caused me to damage. Also be sure to read the right manual! I have an XL and it notes 5mm.

    Fortunately my old screen was beyond repair, But be super careful around the bottom I managed to sever the ribbon cable to the digitizer.

    I broke my screen here. The adhesive in my case was quite strong on the top and bottom.

    Mario Flores - 返信

    This is by far the hardest part of the entire replacement. I ruined my screen doing this, you might as well buy a new screen at the same time as you buy your battery. I just barely rubbed the edges of my screen and it turned the edge of my screen purple. This eventually migrated to the entire screen causing the whole thing to be purple/black.

  6. As you slice around the bottom edge of the phone, do not insert the pick more than 1/4" (6 mm). Slide the pick around the bottom right corner to slice through the adhesive. If the corner feels hard to slice, apply a heated iOpener to the corner for a minute and try again.

    There is a LOT more adhesive at the top than anywhere else on the phone! It’s like there’s 2 lines of adhesive, one along the edge of the case and one along the edge of the screen, and it’s filled in between them wherever the speaker camera aren’t. I needed to heat and pry several times to get the top loose. Fortunately, there’s little risk of hitting a cable near the top (look ahead to the step where you lift the screen off to see where all the cables go!)

    E. Dunham - 返信

    I found that applying the iOpener across the top edge of the glass for about 30 seconds at this step helped soften the adhesive significantly. My front camera was replaced only a few months ago by uBreakiFix and the display adhesive subsequently let go on the entire right edge, bottom, and part of the left side shortly after the new front camera failed. Only the top was still securely stuck.

    Hi, could you help me with one clarification?

    What does the small “metal patch” in the middle of the display ribbon do?

    Does it prevent the phone from starting while disconnected?

    Thank you for your time!

    oliver schirmer - 返信

    Hi Oliver,

    I think the patch you’re referring to helps with either EM shielding or heat dissipation. It should not prevent the phone from starting.

    This may be a silly question but how are you able to tell whether the tape is in good condition? Is it based off of how sticky it is after you remove it?

    Sylvia - 返信

    That is a fair question! If the tape is in one piece and is relatively sticky, it can probably be used again.

    Arthur Shi -

    Oops! I forgot to put any tape back. Does this tape have a critical purpose, in other words should I go to the trouble to pry the screen back off and tape it?

    elyze - 返信

    The tape does not serve a critical purpose. If you have already re-sealed your phone, I wouldn’t worry about it.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

    I had accidentally pressed the power button and the phone was on when connecting the new screen and that broke the board! So make sure the phone is off.

    i had a little plastic piece around the camera (seems to just be a spacer) that i moved to the new screen. had to pry it up with a pick cuz it was stuck down good.

    elyze - 返信

    actually to clarify- i didn’t move the little camera spacer to the new screen- i placed it around the camera on the phone, where there was a little indent for it, and stuck it down with a bit of tesa strip, then applied more tesa strips around the edge of the phone before finally reconnecting and replacing the screen. the little plastic bit i encountered needs to be precisely placed around the camera so would not be a good idea to just stick it to the screen when reinstalling!

    Thanks team! I was able to replace my broken screen with no issues!

    Instead of cutout adhesives or tesa tape, I used B-7000. Painless.

    Appreciate the screen and instructions!

    I have a quick question, so I haven’t done anything yet because I only just ordered my repair kit, but is it possible to replace the battery without having to replace the display ?

    Braeden - 返信

    Hi Braeden!

    Yes, it is definitely possible to replace the battery without replacing the display. With that said, the initial entry steps can be pretty tricky. Before you begin, look very closely over the display to see if you can see any micro-fractures. If you see any, you will most likely crack the screen when you try to remove it. Take your time and apply a heated iOpener often. Good luck!

    Arthur Shi -

    I forgot to order the tape when getting my replacement USB port, so I ended up putting the screen back on without any tape and using regular clear tape on the outside of the phone to keep the screen from falling off. It’s less waterproof, but it’ll do the job until the right part arrives.

    E. Dunham - 返信

    Speaker mesh appeared to already be in place on my replacement screen, so I did not transfer this over from my old screen. That was a huge mistake, sounds were garbled above about 30% volume. Make sure you do this part!

    • Use the point of a spudger to carefully align and push the proximity sensor connector onto the motherboard socket.

    • This takes a bit of patience and finesse. Once you have the connector in place, you can also use a finger to gently press the connector onto the socket.

    • Alternatively, you can remove the proximity sensor from the midframe to reattach it to the motherboard first.

    • Use the point of a spudger to carefully pry the proximity sensor out of its recess on the midframe. The sensor is lightly adhered to the midframe.

Hi Nir,

We are in the process of getting replacement batteries. Because the phone is so new, supply chains have not gotten to offering replacements yet.

Arthur Shi -

Just completed this took, probably took me an hour and half from start to plugging the phone back in after I was done. Seems to have worked very well! Do be careful pulling the adhesive out from behind the battery. If it breaks, it can be a little trickier to get it out. I had to heat up the adhesive through the back of the phone, but once I did that I was able to very carefully pry the battery out, using a pick as a load distributor on the battery.
