Vision Pro’s battery capacity is not small. The 3166mAh figure is actually a misleading statement.

It has been previously reported that the battery capacity of Apple Vision Pro is only 3166 mAh, which is largely considered to be the reason why the headset has only two hours of normal use time on a single charge. However, a whistleblower provided additional calculations, indicating that the reason for the extremely short running time of the device is not the battery capacity, but other reasons.

Total battery life isn't just measured by the "mAh" value, there are other details to consider. For example, the battery capacity of the iPhone 15 Pro Max is 4441 mAh. On paper, its battery is larger than that of the Apple Vision Pro, but in fact the output voltage and "WHr" rating are also important. After considering these parameters, the iPhone 15 Pro Max has a battery capacity of 17.10WHr, while the Apple Vision Pro has a battery capacity of 35.9WHr, which is more than double the iPhone components.

According to ShrimpApplePro, if the battery capacity of Apple Vision Pro is similar to that of the iPhone, then the battery capacity of this headset will be approximately 9000mAh, which is larger than the battery capacity of two iPhone 15 Pro Max. So, the main question now remains: Why is Apple's mixed reality headset only good for two hours? This is because Apple’s VisionPro has a variety of power-consuming components. The first is two 4K microLED panels, which are the absolute biggest power consumers. Any existing 4K resolution panel will quickly drain battery life.

As for the pairing of the M2 and R1 chipsets, it's unclear how much power the two custom SoCs consume when running simultaneously, but the M2 is generally considered a highly energy-efficient Apple Silicon chip that can enable portable Macs to last up to 12 hours. The weight of the Apple Vision Pro battery case is enough to tell that the company is using a sizable battery unit, but digging into its specs can be a little confusing at times.
