If your Galaxy Note9 battery drains quickly, won’t charge, or won’t power on it may be time for a replacement. Follow this guide to install a fresh battery.
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. If your battery is swollen, take appropriate precautions.
For optimal performance, after completing this guide, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least two more hours. Then use your phone until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.
필요한 것
-
-
Power off your phone before beginning disassembly.
-
Use a hairdryer, a heatgun, or prepare an iOpener and apply it to the right edge of the back of the phone for about a minute to soften the adhesive underneath.
-
-
-
Apply a suction handle to the back cover.
-
Lift with a suction handle to create a gap between the back cover and the frame of the phone.
-
Insert an opening pick into the gap.
It takes so much heat that it is concerning that damage might be caused to the internal parts. It is difficult to heat the glue, pull the case apart and insert the pick at same time. May need some more pointers to handle these situations first, to prevent possible damage. Also what about the glue that is heated and then cooled before opening? Does it run inside and cause greater adhesion after it cools? Another thing, the handling may cause the phone to turn back on while working to separate. Don't know that that is of concern.

-
-
Note that there is more adhesive along the top edge and around the camera bezel than around the rest of the phone.
-
Cut carefully around the left edge near the fingerprint sensor or you risk damaging the ribbon cable inside.
It's extremely easy to crack the back glass when nearing and rounding the corners. It's probably a good idea to soften the adhesive with heat as you go.
Step 5 is NOT "cut through the adhesive", that's steps 5-10. Step 5 is "Begin the careful process of cutting through the adhesive, starting at the right side where you already softened it. Proceed carefully, slowly, and warmly through the following steps."
These comments are spot-on. I never break a phone, and I cracked the back glass following the instructions without seeing these comments first. Heat the back much more than you think you need and go super, super slow.
The bottom inner adhesive layer reaches higher than what you see in the diagram above, so you will have to insert the pick deeper at the bottom and the sides along the bottom to separate the inner adhesive area. Just don't force the corners of the covers upward too much to keep from cracking the glass.
-
-
-
Starting from the center, cut the adhesive up and down the right side with an opening pick.
-
-
-
Leave an opening pick in the upper-right corner.
-
Use another opening pick to cut the adhesive around the bottom-right corner.
-
Leave that opening pick in the phone.
There seems to be a lot of glue at the bottom, I broke the glass as I was cutting past the charging port - not sure if it was already fractured or just not enough heat (I used Sellotape so it didn't break up into pieces!)
I think LOTS of heat & patience is the key!
Be very careful around the corners and bottom (probably top too, but I didn't have a problem there). Make sure you've cut in far enough down the side first (go in about 1cm) but less round the corners and work in slowly.
-
-
-
Use a heat gun or hair dryer or apply a heated iOpener to the left side of the rear panel for at three minutes to soften the adhesive underneath.
If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.
-
-
-
-
Insert an opening pick into the lower-left corner of the rear panel.
-
Using another opening pick, cut the adhesive along the left edge of the rear panel.
Aside from the left edge where the fingerprint sensor cable is, you may have to insert the pick up to 2cm on the sides and top, and a little further along the bottom, and swipe sideways to separate the inner adhesive areas. If one side doesn't separate fully, just apply heat, insert the pick deeper into the phone, and swipe sideways until the back cover detaches. There isn't a need to apply much vertical force, especially on the corners, since the cover will just pop up once all the adhesive has been sliced by the pick.
-
-
-
Using the inserted opening pick, carefully cut the adhesive around the upper-left corner of the rear panel.
-
Finally, cut the last of the adhesive along the top of the phone.
Be VERY patient as you slide the opening picks around the periphery of the glass, and use heat very liberally. Make sure the smooth, clear aspect of the iOpener is against the glass, not the rough black portion.
-
-
-
Separate the right side of the rear cover first.
-
Tilt the cover up along the left edge to expose the fingerprint sensor ribbon cable.
Thought I'd done something wrong here as there wasn't a cable attached to the back - the fingerprint reader hadn't come away with the back, but had stayed with the phone.
Exactly the same experience. Made life a little easier.
Happened to me as well.

-
-
Use the tip of a spudger to pry the fingerprint sensor ribbon cable up and out of its socket.

-
Remove the back cover.
-
Use tweezers to peel away any remaining adhesive from the phone's chassis. Then clean the adhesion areas with high concentration isopropyl alcohol (at least 90%) and a lint-free cloth to prep the surface for the new adhesive. You don't have to clear out adhesive down to the plastic but larger pieces should be removed.
-
Turn on your phone and test your repair before installing new adhesive and resealing the phone.
-
Carefully apply the new adhesive to the back cover, then line up one edge of the glass against the phone chassis and firmly press the glass into the phone.
I am installing a new backplate (this is my first repair; I was CERTAIN that I would crack the back glass, and I was NOT wrong) but I’m not sure how tweezers are meant to remove gooey adhesive! I simply used the blue plastic pry tool as a scraper and gently rolled up the goo. Maybe the glue is different because I have a refurbished phone? That may also explain why I had so much trouble with Step 1. Hope that this helps!
Use tweezers remove any inner adhesive strips that may have started peeling off when the back cover is removed, or adhesive clumps. If an adhesive starts to peel off, use tweezers to pull the strip off completely, and then replace only that removed adhesive strip. Actually, the iFixIt inner adhesive strips don't seem to have the white non-stick areas that are on the original adhesive strips. Thus, it seems ok to keep the original inner adhesive strips if still attached to the phone.
The outer adhesive border is like a good, not a strip, and should be replaced. Using isopropyl alcohol to rub off only the edge adhesive on the phone and back cover works well.
After adding a new outer adhesive and reattaching the back cover, you have one try to align and replace the cover. The cover might not attach flush onto the phone with no side gaps, due to the outer adhesive strip placement. It is probably sufficient if the outer adhesive seals all the way around the back cover border.
While testing the phone after battery replacement, but before reattaching the back cover, if a thermal warning (triangular thermometer icon) appears during charging that prevents charging over 50%, remove the charging cable and use a lightly warmed iOpener or heat gun on the battery to warm it slightly. Once the battery is warmed up a little, reattach the charging cable, and the error should go away. Battery charging can be resumed. This assumes no hardware was damaged during battery replacement.

12 단계 Remove the upper midframe

Use a Phillips screwdriver to remove the nine 4 mm screws securing the upper midframe.
There are two more screws on the bottom right corner of the little side frame that the Qi plate is glued to. I took those out as it put less stress on it.

It helps to hold the fine tweezers with your non-dominant hand to support the screw heads and ensure they come straight out; you can also gently lift as you unscrew.
-
-
-
Peel the wireless charging coil off the battery starting with the left side.
-
-
-
Use the tip of a spudger to disconnect the orange ribbon cable connecting the battery to the motherboard.
-
-
-
Apply 1-2 drops of high-concentration (90% or greater) isopropyl alcohol in the battery well along the bottom and in the upper-left corner of the battery.
-
Wait a couple of minutes for the alcohol to soften the adhesive under the battery.
-
Tilt the phone at various angles to help the alcohol flow under the battery.
-
-
-
Apply a suction cup to the battery.
-
Use firm, steady force to lift the battery straight up until there is a gap large enough to insert the opening pick.
-
Insert an opening pick underneath the bottom edge of the battery and twist to loosen the battery adhesive.
-
Remove the battery.
-
If you used isopropyl alcohol, wait ten minutes before installing the new battery to allow the alcohol to completely evaporate.
Zero chance of the iFixIt suction cup sticking to the battery as it is too big so hangs over the side and doesn't get a seal.
I used loads of IPA, waited, tilted phone about, more IPA, more tilting, more IPA and prised the battery a bit at the bottom with a spudger, more IPA, prised a bit more at the bottom then (gently) prised it from the top left and it came out.
Der Saugheber hat gar nicht gehalten. Den Akku damit anzuheben war unmöglich. Stattdessen habe ich den Akku durch seitliches hebeln mit dem "Jimmy" Werkzeug heraus bekommen.
The iFixIt suction cup doesn't work, as stated in the other comment. After injecting the alcohol, you can insert a spudger into the hold at the top-left corner of the battery. It seems like this hole was made for the purpose of popping out the battery. You could probably also use a pick on the bottom center of the battery to pop it out. Just pull it out slowly.
If you plan to replace the battery adhesive, the adhesive doesn't seem to stick to the battery directly, so I instead stuck it into the battery compartment over the existing adhesive, and then placed the battery on top.
When reinserting the new battery, you may want to push the the battery higher up in the compartment, so that the battery cable more easily aligns with the connector on the phone. It may take a few tries to align the battery perfectly. Even with the new adhesive, the battery doesn't stick much, which is fine, so that it can come out more easily next time. It's enough to maintain friction to not move around I think.
If this is your first battery swap for the phone, consider peeling off the Note product sticker from the old battery and reattaching it to the new battery if you want to keep it.

Great to hear Robert, and good job!
Good Evening Samo,
Thanks for the step by step instruction, they are perfect.

Do you just reheat the adhesive or do you need new/more adhesive?
If using an iOpener it will need to be fully heated and set on for at least 5 minutes. You’ll know the phone is hot enough when its almost too hot to touch.
Spencer Barron - 답글
Just came here to say exactly that. The instructions should be amended to state that: "Get it fully hot and leave it there for at least three minutes solid."
