iPhone 7 smart battery case. It has quite a few scratches, and the silicone part is deteriorated and peeling off. It's an Apple genuine product. It can also be used with iPhone 8, SE2, and SE3. The "iPhone 7 Smart Battery Case" is an iPhone 7 case with a built-in battery that extends the talk time of the iPhone 7 to a maximum of 26 hours and video playback time to 24 hours. The regular Apple Store price is 10,800 yen. I used it with my iPhone 7, but I stopped using this battery case after my iPhone 7 broke, so I'm selling it. I used it for several years. If you use this, I think the battery lasted longer, from half a day to a full day. The exterior was covered with silicone, but it has deteriorated and is gone. It is recommended for those who don't mind the appearance or want to repurpose it. #iPhone #iPhone #smart #battery #case #external #external #genuine #iPhone #iPhone7 #iPhone8 #iPhone7 #iPhone8
