How to find out the correct APN number of the battery?
the battery of my iPhone 5s startet to get weak, so I decided to replace it. I ordered a new one but did not verify the correct APN number of the old battery. Unfortunately the new one is not working with the iPhone. It is not charging nor turning on. My bad, I also gave the old battery already to an recycling service.
Is there a way, I can find out the corresponding APN to my iPhone without doing trial and error byuing 5 or more different batteries?
Is this a good question?
