Follow this guide to replace a dead or worn-out battery in your Samsung Galaxy S24.
This guide is for the battery itself. If you're replacing the screen and battery assembly (the frame, screen, and battery as one piece), follow this guide.
Your phone's lithium-ion battery has a limited lifespan. If your phone dies quickly and doesn't hold a charge, it may be time to replace the battery.
Note: Retaining water resistance after the repair will depend on how well you reapply the back cover adhesive, but your device will lose its IP (Ingress Protection) rating.
