Samsung Galaxy Note8 Battery Replacement

你所需要的

  1. Samsung Galaxy Note8 Battery Replacement, Back Cover: 步骤 1 中的图像 1,1
    • Switch off your phone.

    • Prepare an iOpener for softening the adhesive on the back of the Note8.

    • Apply the iOpener on the back of the Note8 along the side with the power button.

    I used a heat gun to soften the glue - worked it around the edges, moving the heat gun quickly. As this is my first attempt, I’m still calibrating on this - but other guides mention getting the back cover hot enough so as it’s just too hot to touch. I also have a temp probe on my multi-meter, and I measured appx. 75 deg. C.

    One of the other guides showed using a electronics hot plate set to 105 deg C for 60 sec.

    • Use a suction handle to lift the back cover and create an opening pick to get in the gap.

    • Since the back cover is also slightly curved at the edges you want to insert the opening pick at a lower angle from underneath.

    • Start at the middle of the side and cut the adhesive while pulling up with the suction handle.

    • Be careful not to lever the opening pick too much to avoid breaking the back cover. Rather pull with the suction handle and use the pick for cutting the adhesive.

    • Move the pick towards the bottom corner and leave it there to keep the adhesive from resealing to the case.

    • Use another pick and move it to the top corner.

    • If it's getting harder to move the pick you might need to reheat the iOpener and apply it to the back cover again.

    I used an X-acto knife with the flat blade to get it started. I tried using the suction cup - but it’s difficult to get good leverage. Once I got the cover started - I used the metal pry tool (sharpened with a dremel file) and a business card to work it open.

    This is definitely the hardest part.

    Once off I see all the glue on the curved part of the chassis NOTON THE BACK. Apply heat to curved edges.

    • Again take another opening pick and carefully move it around the corner and along the top edge.

    • Reheat with an iOpener if necessary.

    • Leave the pick at the top right corner to keep the adhesive from resealing.

    • Rotate the device and start to separate the adhesive at the bottom with another opening pick.

    • Leave the pick at the bottom right corner to keep the adhesive from resealing.

  5. Samsung Galaxy Note8 Battery Replacement: 步骤 5 中的图像 1,3 Samsung Galaxy Note8 Battery Replacement: 步骤 5 中的图像 2,3 Samsung Galaxy Note8 Battery Replacement: 步骤 5 中的图像 3,3
    • When the adhesive has been separated on all three sides properly you will be able to slowly lift the back cover.

    • Don't force it open. Use an iOpener to again soften the adhesive if the back cover won't come off or starts to bend.

    • Pay attention to the fingerprint sensor connector when flipping the back cover open. You might need to disconnect it as described in the next step.

    I broke the back camera cover for the NUT 8 and then I bought a commercial cover and installed it but the quality of the picture became very bad and my question is, do you know where to get the original cover at a reasonable price?

    • Use a pair of tweezers to disconnect the fingerprint sensor.

    • The connector might already have come off when flipping the back cover open.

    don't skip disconnecting the sensor, even if isn't still glued to the case. it has to move away from the NFC/charging coil assembly in order to free the latter so it can be lifted away from the battery.

    • Remove the back cover.

    • To prepare for the reassembly remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    How do you swap the fingerprint sensor

    Lukus Carr - 回复

    You can use a tweezer to swap the fingerprint sensor, you might be careful when doing the step 6, additionally, a tweezer will be helpful when reassemble the fingerprint sensor. please note that your new back cover needs to have the fingerprint adhesive on. most of the product did not have. i have get a LUVSS brand from amazon which came with all OEM adhesive and full set tools, even a B6000 glue, best option to go for replacing the note 8 back glass

    • Carefully pull up the complete charging coil and NFC antenna assembly.

    • The bottom left part of the assembly is slightly glued down to the frame.

  11. Samsung Galaxy Note8 Battery Replacement, Battery Disconnect: 步骤 11 中的图像 1,1
    • Use the flat end of a spudger to disconnect the battery connector.

  12. Samsung Galaxy Note8 Battery Replacement, Battery: 步骤 12 中的图像 1,1
    • Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath the battery. Reheat and reapply the iOpener as needed.

    • Alternatively or when the battery is blown up, you can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for several minutes to help weaken the adhesive.

    Isopropyl alcohol worked great but flooded the main board and took all night to dry out

    • Use the flat end of a spudger to pry up the battery from the top right corner.

    • You will be prying against the case directly above the mainboard. Pry carefully to avoid damaging any close components.

    • You may need to reheat and reapply the iOpener repeatedly to further soften the adhesive. The adhesive is tough and it may take a few tries to get the spudger started under the battery.

    • Use the spudger to pry up the battery until you can insert an opening pick to prevent the adhesive from resealing.

    • Try your best not to deform the battery during this process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.

    I really think this is much less risky if you just take out the motherboard. There is much less risk to heat the other components when you are loosening the battery adhesive and you can be more rough when getting the battery out. Especially (but not exclusively) if you are changing the screen anyway. Should be after step 29.

    Additionally, I went at the battery from the side with a credit card and prying out the battery evenly across the length of the battery. I was even able to make a ‘ridge-peek’ from the card and screen and heat it from above while pushing down on the card and prying at eh same time. I got it out without any battery deformation. I would get one of those flat credit card shaped tools if I did it again because the credit card deformed and I had to keep flipping it.

    Didn’t need to heat or use alcohol to get the battery out - just gently kept prying. I used the metal pry tool that came with the battery replacement tool kit. But very careful not to puncture the old battery.

    • Use the flat end of the spudger to pry up the top left corner of the battery where the flex cable is located.

    • Slide the spudger along the side of the battery to break apart remaining adhesive.

    • When prying keep to the areas marked orange. Avoid the red area in the middle which is the back of the display.

  15. Samsung Galaxy Note8 Battery Replacement: 步骤 15 中的图像 1,1
    • Lift the battery out of the case.

    • Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

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

    • Follow this guide to install battery adhesive.

    • Follow this guide to install custom-cut adhesives.

    do you mean when replacing display the battery should also be replaced?

    John Kenneth - 回复

    Hi John,

    Since you can replace the display without removing the battery, you do not need to replace the battery.

    Arthur Shi -

    Great guide!

    Quick note. If you are changing out the back cover or cant get touch ID reconnected Warm it up some on the back cover. It should pop right off with a spudger. Then reattach it inside the phone. Make sure the adhesive on back cover is sticky enough to hold it in place. Then set back cover on top!

结论

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place for 5-10 seconds.

To reassemble your device, follow these instructions in reverse order, replacing the adhesive where needed.

If possible, turn on your phone and test your repair before closing and sealing up the phone.

For best results, when your repair is complete, calibrate your newly-installed battery.

Awesome fix. Do you have anything for the front glass replacements by chance? I want to do both at the same time

Rick Moore - 回复

For those wondering how to apply the replacement adhesive, there is a video on the iFixit YouTube channel about installing adhesive on Samsung devices. Its a bit generic, but it points you in the right direction.

Hi Christopher,

I’ve edited the last step to include some adhesive guides! Hope that helps!

Arthur Shi -

Thanks!! Very good detail. I was able to get the back cover off and replace the battery - the phone is working like a champ!

Would it be possible to augment the mAh? instead of 3300 mAh giving a little bit more power?

William Houli - 回复

I think there is a 3rd party manufacturer who sells 3600mAh instead of 3300 so I guess yes.

Amiyo Paul -

How do you PUT IT BACK TOGETHER? especially the fingerprint scanner part?

Titan Rock - 回复

The fingerprint can be a tricky maneuver! Align the connector carefully over the socket, and use your finger or the flat end of a spudger to press it in place. It may take a few tries. Patience is key!

Arthur Shi -

Does any one know how undo what I did after following above instructions to replace battery?

I see some dead pixel and cracked back panel :(
