Galaxy S22 Ultra Battery Replacement
On the Galaxy S22 Ultra the battery comes out through the back. The back glass is glued on, and the battery is glued to the frame, so this repair is mostly about patience with heat and alcohol.

Open the back
Power off and remove the SIM tray and S Pen
Power off the phone and pull the SIM tray, then push the S Pen in and pull it out of its slot. Samsung back glass is thin and bonds hard, so cover it with packing tape if it’s cracked.
Heat the back glass
Warm the edges of the back glass evenly for 3–5 minutes. Samsung uses stronger adhesive than Apple, so expect to reheat a couple of times. Keep the heat moving and away from the camera lenses.
Cut the back glass adhesive
Lift near the bottom edge with a suction cup just enough for a hairline gap, slide a pick in and work it around all four sides, leaving picks in the gap so the adhesive doesn’t reseal. Keep the pick shallow at the top near the cameras.
There is no cable attached to the back glass on these phones, so once the adhesive is cut the glass lifts straight off.
Cut both long sides first, then slide the glass down slightly and cut the top. Remove the wireless charging cover
Remove the Phillips screws around the top plastic cover (it carries the wireless charging and NFC coil) and lift it off. Some models have a bottom cover over the speaker too; remove its screws and lift it off.
Disconnect the battery
Unplug the battery cable first with the flat end of a spudger, before you touch any other cable. Then unplug the long main cable that crosses the battery and links the logic board to the charging port board.
Battery off first and back on last, so the phone stays dead while cables are moving. Schematic, not to scale.
Remove the battery
Soften the battery adhesive
The battery is glued to the frame with no pull tabs on most of these models. Drip isopropyl alcohol along the edges of the battery and let it soak in for a minute or two. If your battery does have pull tabs, use them instead.
Lift the battery out
Starting from the bottom edge, slide a plastic card under the battery and lift slowly, adding alcohol as you go. Never use metal, never bend the cell, and stop if it swells, smokes or smells. Put the old battery straight into a metal can of sand.
Install and close
Clean and seat the new battery
Wipe the old adhesive off the frame with alcohol and let it dry. Apply the new battery adhesive, line the battery up in the bay and press it down firmly across the whole cell.
Reconnect and close
Plug in the main cable, then the battery last. Refit the top and bottom covers and their screws. Clean the back glass and frame, lay new back glass adhesive, press the glass on and clamp it for several minutes. Slide the S Pen and SIM tray back in.
Test and finish
Charge for a few minutes before powering on, then check wired charging, wireless charging and NFC. A poorly seated back can make wireless charging slow or unreliable.
