The parts are not interchangeable. The mounting brackets, electrical contact pads and the connector at the top right has changed.
Chalk this up to learning and get the part needed to your phone.
- The volume of space inside phones is so low that even a slight bend in the part with the electric traces will mean you can’t even close the case physically. You’re missing the bottom right component and that large flap won’t fit wither as the 6s part is much shorter above the lightning receptacle.
- Worse if you damage the connectors or short the circuitry. Read the battery thermal event pages in the iPhone 14 official repair manual. This piece will be close to your battery so please be safe.
For the iPhone 14 Repair Manual, you’re in both the Warning and Caution alert category if you try to use the part you ordered.
Failure to follow alerts could result in fire, injury, data loss, or damage to the device, parts, or other property.
Warning - Instructions for reducing risk of personal injury
Caution - Instructions for reducing risk of data loss or device hardware damage
