Use this guide to replace the battery on your Samsung Galaxy Note20 Ultra.
For your safety, discharge the 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.

Great guide! Much appreciated! I've opened the phone twice now due to not gluing enough the first time. I wish iFixit sold a battery for the N20 Ultra. I had to get generics and one was total garbage.

where did you buy the new battery from?
What is the precut adhesive card used for?
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.
