Réponse à : « iFixit replacement batteries, are they genuine Apple batteries? »I asked this question from ifixit customer services and here is their reply: " The iPhone 4 Battery we sell is made to the same specifications as an Apple OEM part, but cannot be classified as 'OEM' because they are not made by Apple. Apple doesn't like to sell their OEM parts to anyone, so they are extremely hard to find. Our parts are brand new, fully tested, and made to the same quality as Apple OEM parts. They also come with a 6-month warranty." Hope this helps.
