Detailed overview: Samsung Galaxy S24 EB-BS921ABY 4000 mAh battery
When a Galaxy S24 stops making it to bedtime on one charge, the factory battery is almost always the reason. This EB-BS921ABY replacement, sized for the Galaxy S24 (SM-S921U and SM-S921U1), is built to the phone's original 4000 mAh capacity, the same rating Samsung used at the factory.
The battery ships new, along with adhesive strips and a full installation toolkit (spudgers, screwdriver, opening picks), so the swap can be done at home in under an hour with a bit of patience, or handed to a local repair shop.
Replacing the battery instead of the phone costs a fraction of an upgrade and keeps a working device out of the landfill. Because the S24's back glass is glued down, work slowly around the edges and take care with the ribbon cables underneath; recycle the old battery at a proper collection point once the job is done.
