Apple Vision Pro is connected to a small battery, which has a capacity of 3116 mAh. By modern standards this is not much, but not everything is so simple.
Two measurements are commonly used to measure battery capacity: milliamp hours (mAh) and watt hours (Wh).
Milliamp hours Measure the charge while watt hours measure electrical power.
Milliamp hours are important when choosing battery capacity because they indicate how much electricity the battery can store. Watt hours determine the amount of electrical energy working or consumed.
The battery in the Vision Pro has a capacity of 3116 mAh or 35.9 Wh, and also produces a voltage of 13V 6A. Simply put, Apple has packed a very large battery into a small package.
If you convert those watt-hours into an iPhone battery, you get a value of about 9,000 mAh. Agree, this is important.
But if you still compare the Vision Pro’s battery in watt-hours with other Apple devices, it will be somewhere in the middle between the 11-inch iPad Pro (28.65 Wh) and the 12.9-inch (40.88 W).
So why does the Vision Pro only last two hours if it has such a big battery? In fact, everything is very simple. This one battery powers two bright 4K HDR displays, the M2 and R1 processors, and all the sensors and cameras. The latter work almost constantly, which is why the autonomy is so small. [WccfTech]
