Meta Quest 3: The road to lightweight batteries with negligible impact

News on October 22, recently, iFixit reported on Oculus Quest 3 conducted a disassembly and found that after removing the front panel, the interior was almost occupied by the battery. This raises an interesting question, if the battery is removed from the Oculus Quest 3, how much of an impact will it have on its weight?

Some other headsets, like the Pico 4 and Quest Pro, place the battery in the back of the headband instead of the front. within the display, while the Apple Vision The Pro uses an external battery pack to completely remove the battery from the display. But would removing the battery from the Oculus Quest 3 significantly reduce its weight?

UploadVR reached out to Shahram Mokhtari, lead teardown technician at iFixit who works on the Quest 3’s teardown and asked about the weight of the battery after removal. He replied that the battery was only 64 grams.

Without taking into account the mask and headband, the Oculus Quest 3 weighs 397 grams, which means the battery only accounts for 16% of the overall weight.

Of course, that 397-gram figure includes the side arms and speakers, and users are unlikely to feel their weight on the head. If they were removed as well, the weight savings would probably be between 20 and 25 percent, although the difference wouldn't be huge.

One way to reduce the weight of the headset is to remove the computing hardware from it, but this will be more complicated from an engineering perspective and may require using thick and Expensive cables to establish connections between computing units and sensors and displays. Additionally, the compute unit will almost certainly be larger and thicker than a smartphone, as it will require a larger battery and cooling fans to support extended reality experiences that require sustained high performance. For example, Magic The Leap 2's computing unit is as big as a belt pack.

However, there are other possible ways to reduce the weight of the headset, such as micro OLEDs are lighter than LCD panels because they have a higher pixel density and don't require an additional backlight layer. Furthermore, despite the fact that like Oculus Quest 3 Such headsets are optimized for top performance, but the future may see headsets aimed at reducing weight, using downclocking chips and lighter cooling components, and maybe even fanless designs one day. .

Currently, thinner headsets, such as the Oculus Quest 3, tend to feel lighter, even if they don't actually reduce weight, because the weight is closer to the user's face.
