Title
Samsung Galaxy S21 Ultra Screen and Battery Assembly Replacement
Introduction
Use this guide to replace the screen and battery assembly on your Samsung Galaxy S21 Ultra.
This guide was performed on the ***SM-G998B/DS*** (international) model. Other models have an additional antenna cable sitting in the left edge of the midframe.
If your battery is swollen, [[What to do with a swollen battery|take appropriate precautions|new_window=true]]. Before disassembling your device, ***discharge the battery below 25%***. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair.
***Note:*** This guide instructs you to replace the full midframe, battery and screen assembly and requires transferring all other components to your replacement part. However, it is possible to replace only the battery or the screen and to reuse your old frame, which requires a very different procedure. Make sure you have the correct part before starting this guide.
If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.
You’ll need replacement adhesive to reattach components when reassembling the device.
