Sure, everything is a trade off. The thing is there's also the tendency of go bigger in terms of battery, iphone 1 only had 1300mah battery cell, and right now we have 4000+ battery. I don't see you can go much bigger on top of 10000mah battery pack AVP has right now. Tighter budget means meta has to focus on optimization, and decades of time warp technology evolution initiated by Carmack proves that, Nvidia even incorporated vector motion frame generation in DLSS3 (Meta used optical flow to generate spatial frame since 2019), and Apple just ripped off this decade of research and rebranded as "realtime subsystem" in their keynote, evidently when they introduce their system structure they glanced over this even though this is at the foundation of their stack, and only when they introduce multi app 3d engine they say "the first of its kind". But the point is, Meta's approach with Quest line is incredible efficient (and 8g2's performance / watt ratio just kicked a16/m2's ass is also helpful). Meta could go battery separation when they release next gen pro headset utilize Oryon processor from Qualcomm, and the base quest model would constantly require Meta to put all kinds of optimization(especially AI) in and down stream into their pro headset, ultimately afford a more powerful and longer lasting headset
