This replacement battery is what you need to bring that dead smartphone back to life.

• 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.
• 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%.
• No warranties are available for iPhone Batteries that are self-installed, which is the nature of errors during the repair process by non-Battery World technicians. Please visit us in person for full warranty and guarantee.
