Introduction
Follow this guide to replace the battery in your Samsung Galaxy S22.
This guide is for the battery itself. If you're replacing the OEM screen and battery assembly (the frame, screen, and battery as one piece), follow this guide.
You'll see references to the Samsung Self Repair Kit throughout this guide. Ignore those bullets, as they don't apply to this guide.
What you need
-
Step 1 Heat the bottom edge
-
Heat an iOpener and apply it to the bottom edge of the back cover for two minutes.
-
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are susceptible to heat damage.

-
Step 2 Adhesive information
-
While you wait for the adhesive to soften, note the following:
-
There's adhesive securing the back cover around the perimeter of the frame.
-
The adhesive is strongest in the bottom right and top left corners.
Edit

-
Step 3 Insert an opening pick
-
Apply a suction handle to the back cover, as close to the bottom edge as possible.
-
Pull up on the suction handle with strong, steady force to create a gap between the cover and the frame.
-
If you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
-
Insert an opening pick into the gap.
Edit
-
-
Step 4 Slice the bottom adhesive
-
Slide the pick back and forth along the bottom edge to slice through the adhesive.
-
Leave the pick inserted in the bottom left corner to prevent the adhesive from resealing.

During reassembly:
-
This is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.

Hi Dennis! At the top of the page next to the Edit button there is a down arrow (⌄). If you click it, you should see an option that says Download as PDF. This should give you a version that's printable.

If one were to open the back panel using a hot air station, how much temperature for how long will do the job without damaging the phone?

did you try?

The guide was very useful, the only problem was opening the phone. It took me two days, but it's just a matter of applying plenty of heat around the edges without exceeding 2 minutes. Once you open one side, the rest is easy. Now, removing the battery can be very challenging. It was very stressful. Apply isopropyl alcohol both to the sides and underneath, but you have to move the battery aside so that it can reach underneath it. I couldn't remove the battery with those plastic things from the iOpener, luckily I had a thin metal tool that I bought from AliExpress a long time ago in a kit, and that helped me a lot. It looks like the thing JerryRig uses (or used to use) when he does a teardown. I just inserted it on the sides and started prying. Even though it bent, I could hear the glue coming off, so I took advantage and added more 99% isopropyl alcohol until it finally came out. The rest is just putting in the new battery and reconnecting everything.
