    New OEM Original Samsung Galaxy S23 Ultra 5G Battery | Genuine EB‑BS918ABY 5000mAh Replacement for Model S918

    Q1: Is this the official Samsung battery for the Galaxy S23 Ultra 5G?

    Yes! This is the 100% genuine Samsung battery with part number EB‑BS918ABY, designed and manufactured specifically for the Samsung Galaxy S23 Ultra 5G (Model S918). It’s the exact same high‑capacity battery that originally powered your phone, ensuring perfect compatibility, safety, and performance.

    Q2: Why should I choose the original Samsung battery?

    • Guaranteed phone recognition – Your S23 Ultra’s software will immediately detect the battery with no error warnings, supporting accurate battery health monitoring in Samsung Members and device settings.
    • Full charging feature support – Works perfectly with Super Fast Charging 45W, Fast Wireless Charging 2.0, and Wireless PowerShare (reverse charging).
    • Advanced safety protection – Built with Samsung’s multi‑layer protection circuitry to prevent overcharging, overheating, and short circuits.
    • S Pen & camera ready – Provides stable power for the integrated S Pen and the advanced 200MP camera system during extended use.

    Q3: What battery life can I expect after replacement?

    With this genuine 5000mAh battery, your Galaxy S23 Ultra 5G will return to its flagship endurance:

    • All‑day+ heavy usage – Up to 14–18+ hours of screen‑on time with mixed use (5G browsing, streaming, productivity, S Pen use).
    • Gaming & media optimized – Stable power delivery supports the Snapdragon 8 Gen 2 chipset and adaptive 120Hz display without unexpected shutdowns.
    • Reliable standby – Excellent charge retention overnight and support for Always On Display without excessive drain.

    Q4: Will this battery fit perfectly in my S23 Ultra?

    Absolutely. The EB‑BS918ABY is engineered to Samsung’s exact mechanical, electrical, and thermal specifications. It matches the original battery’s dimensions, connector layout, and adhesive placement—ensuring a secure installation that maintains the phone’s IP68 water resistance when properly sealed.

    Q5: Can I install it myself?

    Replacing the battery in the Galaxy S23 Ultra requires specialized tools and experience due to its fully sealed, adhesive‑based construction. If you are experienced, you will need:

    • A heat gun or hair dryer to soften the rear adhesive
    • Precision pry tools and plastic opening picks
    • New adhesive strips or pre‑cut gasket for resealing

    For most users, we strongly recommend professional installation to preserve the IP68 rating and avoid damaging the display, rear glass, or internal components.

    Q6: What are the risks of using a non‑Samsung battery?

    Third‑party or counterfeit batteries often lead to:

    •  “Unknown battery” warnings or incorrect battery percentage readings
    •  Inability to use Samsung‑certified 45W Super Fast Charging or wireless charging
    •  Faster degradation and potential swelling, risking damage to the display or mainboard
    •  No support for Samsung’s software features, including 85% charge limit (Protect Battery) and adaptive power management
    •  Possible safety hazards due to inferior protection circuits

    Q7: Is there a warranty?

     Yes, this genuine Samsung battery is backed by a 12‑month replacement warranty against manufacturing defects.

    Simply put:
    If your Galaxy S23 Ultra 5G battery no longer lasts through the day, the genuine Samsung EB‑BS918ABY 5000mAh battery is the trusted, high‑performance replacement that restores all‑day power—with full support for 45W fast charging, wireless charging, the S Pen, and Samsung’s intelligent battery management.

    Power your flagship. Trust Samsung original.
