Information

☝ Lithium batteries can be recharged at any time. It is not necessary to wait until they are completely discharged, nor to fully charge them for optimal performance. On the contrary, don't wait until your battery is empty to recharge it. For optimal conservation of a lithium battery, it is important not to leave the electrons inactive for too long.

☝ Your iPhone's battery may require software recalibration in order to display autonomy corresponding to the actual charging capacity. In order to recalibrate your battery, simply let your iPhone completely discharge until it turns off, and recharge it to 100%.

☝ Depending on the iOS installed on your iPhone and the model of your iPhone, you may no longer have access to the status of your battery and receive a system message saying that the authenticity of the battery cannot be verified. Apple inserted chips into every iPhone battery starting in 2018. This allows your iPhone to recognize the authenticity of your battery by its serial number paired with the motherboard. Apple wants to force users to repair devices at an Apple authorized center. Original or not, this message is inevitable. This does not interfere with the proper functioning of your iPhone which will have regained all its autonomy thanks to this new battery. This message will disappear after 15 days.
