Frequently Asked Questions

Does this battery fit the Samsung Galaxy S23 Plus or S23 Ultra?

No, this part is intended exclusively for the Samsung Galaxy S23 (code EB-BS912ABY), being incompatible with the Plus or Ultra models which use different capacities and physical sizes.

The phone restarts under heavy use, does changing the battery resolve it?

If the previous battery has marked chemical degradation and cannot support peak consumption, the swap resolves it; however, if there is a short circuit on the mainboard the symptom persists, so you must confirm the diagnosis before final assembly.
