  1. Samsung Galaxy Note20 Ultra Battery Replacement, Heat the rear cover: шаг 1, изображение 1 из 1
    • Completely power off your phone before you begin disassembly.

    • Heat an iOpener and apply it to the left side of the rear cover for one minute.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the screen and internal battery are susceptible to heat damage.

  2. Samsung Galaxy Note20 Ultra Battery Replacement, Insert an opening pick: шаг 2, изображение 1 из 3 Samsung Galaxy Note20 Ultra Battery Replacement, Insert an opening pick: шаг 2, изображение 2 из 3 Samsung Galaxy Note20 Ultra Battery Replacement, Insert an opening pick: шаг 2, изображение 3 из 3
    • Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible.

    • If your back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken panel.

    • Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.

    • Don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

  3.

    • Slide the opening pick along the left edge towards the bottom left corner to cut through the adhesive.

    • Leave the pick inserted in the bottom left corner to prevent the adhesive from re-sealing.

    • While cutting through the adhesive, don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

    • Repeat the process of heating and cutting the adhesive along the three remaining sides of the rear cover.

    • You can insert each new opening pick in the gaps created by the opening picks left in each corner.

    • As you proceed, leave an opening pick in each corner to prevent the adhesive from re-sealing.

    • Slide an opening pick back and forth around the entire perimeter of the phone to release any missed adhesive. Reheat any stubborn adhesive.

  6. Samsung Galaxy Note20 Ultra Battery Replacement, Disconnect the wireless charging coil: шаг 6, изображение 1 из 2 Samsung Galaxy Note20 Ultra Battery Replacement, Disconnect the wireless charging coil: шаг 6, изображение 2 из 2
    • Use the pointed end of a spudger to pry up and disconnect the wireless charging coil press connector.

    • Take care to pry only under the edge of the connector to prevent damaging the socket itself and surrounding components.

    • 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.

  7. Samsung Galaxy Note20 Ultra Battery Replacement, Disconnect the white press connector: шаг 7, изображение 1 из 2 Samsung Galaxy Note20 Ultra Battery Replacement, Disconnect the white press connector: шаг 7, изображение 2 из 2
    • Use the pointed end of a spudger to pry up and disconnect the white press connector located in the bottom right of the motherboard shield.

    • Use a Phillips screwdriver to remove the six 4.0 mm screws securing the motherboard shield.

    • If these screws have not been removed before, they may be difficult to remove as they have threadlocker on their threads.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

    • Flip the secondary interconnect cable away from the battery.

    • The secondary interconnect cable is still attached to the phone by a ribbon cable. You only need to move the cable enough to access the battery.

    • Do not bend the ribbon cables more than necessary. Excessive bending may damage the cables.

    • Take care not to bend the battery—a bent battery may leak dangerous chemicals or cause a thermal event.

    • If the battery does not appear to be separating from the frame, apply a few more drops of isopropyl alcohol and wait two minutes before trying again.

    • The adhesive underneath the battery is strong. You might need to apply isopropyl alcohol and pull up on the suction cup multiple times to loosen the battery.

  25. Samsung Galaxy Note20 Ultra Battery Replacement: шаг 26, изображение 1 из 2 Samsung Galaxy Note20 Ultra Battery Replacement: шаг 26, изображение 2 из 2

    • Push the pick under the battery to cut through the adhesive and detach the battery from the frame.

    • Don't insert the opening pick more than halfway to avoid damaging the fingerprint sensor underneath the battery.

    • Don't try to forcefully lever the battery out. If needed, apply a few more drops of alcohol to further weaken the adhesive. Never deform or puncture the battery with your pry tool.

  26. Samsung Galaxy Note20 Ultra Battery Replacement: шаг 27, изображение 1 из 1
    • Pull up on the suction cup to remove the battery.

    • The battery will come out without much force once the isopropyl alcohol has adequately penetrated the battery adhesive.

    • If there's any alcohol solution remaining in the phone, carefully wipe it off or allow it to air dry before installing your new battery.

    • During reassembly, remove the old adhesive and apply stretch release adhesive strips, double sided adhesive tape, or pre-cut adhesive to secure the new battery.

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

where did you buy the new battery from?

What is the precut adhesive card used for?

Fabian Charlton - Ответить

Thank you so much!!! My battery was starting to bulge badly. While the life was still satisfactory, the shape of my phone was beginning to become very distorted, the side buttons no longer worked properly in my DBrand case, and when I pressed my finger on the fingerprint sensor, my screen would depress and click. Not only did you offer the battery and tools needed, but a perfect guide to installing it. Simply amazing.

I just wish you would lose the ridiculous communist imagery on your branding. Repairing products is not communist, it just makes sense. Let's make right to repair an American virtue again, and not model the movement off some Maoist revolution.
