How to replace Samsung Galaxy Note 9 battery

Unlike the previous Galaxy models, users can no longer pull out the battery of the new Samsung Galaxy Note 9. It means that they would need help from a technician to be able to replace the battery so any battery replacement process should be done only by an authorized technician and you should know as early as now that removing the back cover of your device will compromise its IP68 certification and that would surely void the warranty.

If you think that you need to replace the battery of your Galaxy Note 9, nothing could stop you. After all, it’s your phone and paid for it. However, if you haven’t tried dissecting your phone before, then I would say that doing so would be a challenge because you will have to go through all the hassle of slicing through all the glue that keeps the components together.

Step-by-step instructions to remove & replace Galaxy Note 9 battery

Depending on your know-how in opening up smartphones, the following steps may be easy or very difficult to do…

  1. Using a heat gun, hit all sides of the back cover of your phone until it’s warm enough. Only this way you can soften the glue that holds the back panel.
  2. Using repair or guitar picks, carefully slice through the glue by inserting them in between the display and back panels but be careful not to push those picks too far so that you won’t mess up some components inside.
  3. Use suction to lift the back panel slowly but don’t lift it more than half an inch as you may break the flex cable of the fingerprint sensor. Removing the back panel could take several minutes to complete and needs a whole lot of patience as it’s the most difficult component to remove and Samsung did a good job in making sure Note 9 is well-protected from liquid.
  4. Once the back cover is removed, you should already be able to see the frames that also protect and hold the components in place. They are secured by standard Phillips screws so you shouldn’t have any trouble removing them. Just be careful not to damage any components.
  5. Remove the camera, iris scanner and a few Phillips screws and then you can remove the motherboard and it should be much easier to do than removing the back cover and the battery but just be careful not to accidentally damage other component.
  6. Once the motherboard is removed, you can now use an adhesive remover to remove the battery. You can’t use a heat gun with it because batteries may explode when exposed to too much heat. The adhesive remover should do the job to loosen the battery and you can remove it eventually.
  7. You may then replace the battery with a new one and do all these backwards. The most challenging part is how to glue them all back together like they were before.

If you’re one of the people who are willing to take risks just to fix their phones, then this should work for you but if you want to be certain to have a working phone after the repair, you must let a technician handle it for you. You should be able to find cellphone repair shops near you but then you will have to pay for the tech’s services and if you’re wondering how much would that be, well, it depends but I’m sure it isn’t expensive. Good luck!
