Translating step 8

Step 8
With the rear case nearly hollowed out, we finish with an X-ray that leaves us with a few lingering questions. Despite the lack of a second battery connector, we can’t help but stare at this charging coil and wonder what might have been. If bilateral charging were included in the final production design, we wouldn’t necessarily expect to see a radically altered coil—but a bigger battery and additional thermal management would almost certainly be required, as reverse wireless charging is thirsty and inefficient, throwing off a lot of heat. In the case of this iPhone 11, we’re not really seeing either of those things.

  • In the case of this iPhone 11, we’re not really seeing either of those things.

  • Perhaps related to the missing second battery connector, we also see the omission of the new battery charging board we found in the Pro Max.

  • Finally, just like in the Pro and Pro Max, our handy X-ray reveals what we believe to be UWB-related antennas carefully embedded into the rear case.

リアケースの大部分を取り出して、X線画像を撮影すれば分解は終了ですが、ここで解決できていない質問が幾つか残ります。2番目のバッテリーコネクタがないにも関わらず、この充電コイルを眺めると、本当のところAppleはどうしたかったのか考えずにはおられません。

最終の製品デザインに、双方向ワイヤレス充電が組み込まれていたとしたら、コイルがここまで大幅に修正されてはいなかったでしょう。しかし双方向ワイヤレス充電は消費電力が大きく、膨大な熱を発生させるため、より大きなバッテリーと熱処理管理を改善しなければなりません。

このiPhone 11の場合、これらの要素が見当たりません。

2番目のバッテリーコネクタがないのに関連して、Pro Maxに搭載されていた新バッテリー充電ボードも不在です。

最後に、ProとPro Maxと同様に、便利なX線画像で明らかとなるのは、超広帯域無線(UWB)関連のアンテナがリアケースの中に埋め込まれているだろうということです。
