Introduction
This guide shows how to remove and replace the battery for the Samsung Galaxy S20 Plus.
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.
-
-
Apply a suction cup to the back of the phone, as close to the center of the bottom edge as possible.
-
Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

Insert the point of an opening pick into the gap.

Slide the pick back and forth along the bottom edge to slice through the adhesive.

Leave your opening pick in the seam to prevent the adhesive from resealing.

Do you need new adhesive to glue the front and back of the phone itself back together after replacing the battery?
That is insane !!! I am replacing my Note 4 with an S20+. With the Note 4, one just opens the back, lifts the battery out and clicks in the new one. 10 seconds or less. I will NOT be trying to perform this 31 step, 30-60 minute replacement if the battery on my S20 needs replacing. Cheaper to replace the %#*@ phone. WTF were Samsung thinking???
I don't know if the overseas version is different from the Korean model I have (it's probably the same), but I've heard stories from repair shops that the liquid crystal died because they used alcohol to remove the battery. In fact, after the replacement, the liquid crystal was slowly dying and then completely dead the next day. The only thing they said to do to remove the battery was to apply a lot of heat. Other than that, the rest of the steps seem to be fine. I just changed my phone to an S21+ because the liquid crystal was expensive. I signed up to try this. I hope everyone else has no problems replacing it...(it's not hard, except for the back plate and battery removal, which is a pain).
This happened to me unfortunately
