Introduction
This guide shows how to remove and replace the battery for the Samsung Galaxy S20 Ultra.
The battery is held in place with strong adhesive. High concentration (over 90%) isopropyl alcohol is necessary to loosen and release this adhesive.
If your battery is swollen, take appropriate precautions and do not heat your phone.
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.
You'll need replacement adhesive in order to complete this repair.

The new battery stays at zero percent when it’s charging
But it charges or not?
Where did you buy this battery, avoid ebay only buy from trusted sources with warranty like ifixit
I bought a galaxy s7 battery on eBay claiming to be original quality it swelled up badly in 2 days
I completed this repair yesterday and for awhile everything was working. Now it looks like there’s residual isopropyl alcohol in the camera assembly and the screen is no longer working. For awhile touch input stopped but the display remained and now the display has stopped as well. I’m worried I damaged something by using too much alcohol when getting the battery out, or maybe on the display cable when reattaching it during reassembly. How do I go about finding out what the issue is and hopefully fix it?
This exact issue happened to me as well, word for word how you put it. Took my phone to a repair store and they said the motherboard was damaged and there was nothing they could do. The wording this guide had before was extremely dangerous and probably killed a lot of people's phones.
