手順14
Looks like this year at Apple, big is in. The iPhone 11 Pro Max's powerhouse pumps out 3969 mAh at 3.79 V, for a total of 15.04 Wh. That's a whopping 2.96 Wh more than the XS Max battery, and 1.52 Wh less than the Galaxy Note 10+ 5G battery. Where does this massive power come from? It's 4.6 mm thick, has a volume of 23.8 cm³, and weighs in at 59.6 g. Compared to the XS Max, that's 0.7 mm thicker, 4.2 cm³ larger by volume, and 13 g heavier. We were suspicious when Apple alluded that the new A13 chip and PMU alone were responsible for the extra five hours (five hours!) of battery life. Turns out you can just make a phone a little thicker for massive battery life gains. Who would have guessed?

  • We saw this same single-cell, L-shaped design last year in the iPhone XS, where we learned about the complexities of internal corners and thermal expansion in battery design.

どうやら今年のAppleでは、大きいものが流行っているようです。iPhone 11 Pro Maxのバッテリーは3.79 V/ 3969 mAh、総容量15.04 Whです。XS Maxのバッテリーより2.96 Whも増えました。Galaxy Note 10+ 5Gのバッテリーより1.52 Wh少ないことになります。

どこでこの巨大なパワーが生まれるのでしょうか?バッテリーの厚みは4.6 mmで、体積23.8 cm³、重量は59.6 gです。XS Maxと比較すると、0.7 mm厚く、4.2cm³大きく、13g重くなりました。

Appleが新A13チップとPMUだけで、バッテリー駆動時間が5時間も増えると述べた時、私たちは疑しく思いました。(なんせ5時間です!)結局のところ、デバイスの厚みを少し増やせば、駆動時間が大幅に延びるのです。だれが予想できたでしょうか?

iPhone XSに搭載されたものと同じL字型シングルセルバッテリーです。その分解では、内側のコーナーに加わる圧力や熱膨張に対応するための複雑なバッテリー設計を学びました。
