This battery will only work in an iPhone 8. It will not work in an iPhone 8 Plus. Be sure you have identified your iPhone correctly.

  • This battery is brand new! Each one has been tested to confirm that there are no cycles on the cell and that the capacity is 95% or higher.
  • Replace that old, dead or dying battery with a brand new one!

NOTE For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

Warning: Lithium-ion batteries pose a fire hazard if they begin to swell due to age or defect. Learn more about how to safely handle a battery that may be swollen.
