Unexpected battery replacement in preowned iPhone 14 Pro

Normally there will be a notification at the top of the Settings menu informing about the battery. You usually also get a notification after the first setup. You may have overlooked it. The notification in the Settings menu also disappears after a few days, and you therefore have to go into About, and Parts & Service to discover it. That may explain why you haven't noticed it.

But the whole main reason you're seeing the message is because the battery has been replaced. If it says "Unknown" in the service history, it may be because the battery is not original - or not functioning correctly.

If you are nervous, or find that the battery is not working as you expected, then you must contact the place or the person you bought your iPhone from.

I’ve used iPhone for more than a decade now. One of the deciding factors when I’m getting preowned iPhone is that no original part must have been replaced, so I check the parts and service history first before I make a purchase. There was no “parts & service history” when I bought it and weeks after. I just noticed it when I decided to check again today.

Hello~ No one is questioning your knowledge of iPhones nor your right to buy a used one. Do as you please. What I am trying to do is gather enough information to assist you as best I can. It may be a drop, an existing hardware issue or other damage. It may also be that the iPhone was tampered with before you purchased it. Take your iPhone in to Apple and have it checked out…

Hello~ Where did you purchase this iPhone? What do you mean by “parts and service history was not visible”? Did you check it before purchasing here >>Settings > General > About > Parts & Service. Did it say Genuine? Also… sometimes it can be a drop or a hardware failure.

Sorry. We can't help you.

You took your chances on a used device and lost.

You can make an appointment at the genius bar, but it's probably a waste of time. Odds are the phone was tampered with and Apple won't touch it.
