Apple Vision Proのバッテリー容量がその真の目的を明らかにする

Apple Vision Pro’s battery has an enormous energy capacity.

昨日、Apple Vision Pro の開封とレビューの禁止が行われました。の 最初のレビューはすでに出ています, and the unboxings have revealed Vision Pro’s battery capacity.

Apple Vision Pro には、35.9Wh (ワット時) の外部テザーバッテリーが搭載されています。比較のために、Quest 3 には 18.88Wh の内蔵バッテリーが搭載されており、Quest 2 には 14Wh の内蔵バッテリーが搭載されていますが、Quest Pro には後部パッドの裏側に 20.58Wh のバッテリーが搭載されています。

You may have already heard Vision Pro’s battery cited in mAh (milliampere-hours). It’s 3166 mAh, より小さい than Quest 3’s battery, which is 4879 mAh. So how can this be? The trick is that mAh is only a valid way to compare batteries with the same voltage output. But Quest 3’s nominal voltage is 3.87V, while Apple Vision Pro’s is 13V. Because of the different voltages, the normalized way to compare battery energy capacity is watt-hours.

会場 容量 重量
アップルビジョンプロ テザー 35.9Wh 353g
(ハウジングを含む)
メタクエストプロ リアパッド 20.58Wh 104g
ピコ4 リアパッド 20.4Wh 〜100g
メタクエスト3 バイザー 18.88Wh 69g
メタクエスト2 バイザー 14Wh 63g

While it was initially assumed that Vision Pro used an external battery to reduce the headset’s weight, it seems clear now that its true purpose is to support higher performance but more power-hungry computing hardware.

Even with the battery being external Vision Pro weighs 600-650 grams, notably more than the 515 gram Quest 3. And Quest 3’s internal battery is only responsible for 69 grams of that weight. Yet both headsets have the same roughly 2 hour battery life.

It’s conceivable that Apple could have integrated a battery of a similar size as Quest 3 and used an A-series chipset from its iPhones with a relatively negligible net weight penalty. But it didn’t. Instead, Vision Pro features the 10-core GPU variant of the M2 chipset alongside a dedicated R1 coprocessor for handling the headset’s たくさんのセンサー. This enables Vision Pro to deliver roughly twice the performance of Quest 3, and video passthrough free of the distortion that plagues Meta’s solution. But the tradeoff is that it requires a much larger battery – too large to fit in the visor.

Appleは本日予約注文を開始する際に、Vision Proの完全な仕様を正式に明らかにしました。仕様の内訳とQuest 3との比較については、こちらをご覧ください。

In effect, Vision Pro’s battery architecture was chosen to deliver on Apple’s performance targets, not to enable a lighter headset. Whether Apple continues that strategy with future models will depend on its priorities for the future of Vision: will it want to keep pushing performance as far as possible, or prioritize getting rid of the external battery?
