I had a WMR kit that just tore through rechargeable AAa. Using non-rechargeables lasted soooo much longer, and the rechargeables I have are high end!
Got an index and THOSE controller batteries are fantastic.

I am.annoyed at how much power draw the controllers for the Quest use. Had to get rechargeable AAs because it will use up an entire battery in only about 4 hours.
Meanwhile my wireless mouse and keyboard, with RGB lights, are still on the original rando crap brand battery they came with and I always forget to turn them off.

My quest 3 controllers aren’t that bad but they do go through AAs like crazy

Accelerometers do use a relatively large amount of power.
But if your thing has haptic feedback, it’s safe to say the battery is going all into it.

I do try to turn off vibration where possible, because yeah. Those stupid motors use an absurd amount of power for a feature that is pretty useless.

It’s not just that, it’s the whole system.
The human brain has a perception rate of motion up to 300 frames per second and visual data up to 1000 frames per second. Now it’s non-sensical to think of the human eye and brain like a CMOS image sensor and CPU because they simply do not run on the same principles but for the sake of argument we’ll take the upper limit of 1000 frame per second because the brain relies on an intuitive sense of hand-eye position that needs to be processed unconsciously for it to react fast enough to environmental stimulation.
So that’s 1000 times a second minimum (1kHz) for the whole VR system to measure the change in relative position of the controller to the headset in 3 spacial dimensions, 5 degrees of freedom, the acceleration of that change, packet up these numbers, transmit them via a radio link to the headset, unpack that data in multiple processing threads all waiting for their sprint in a CPU core, get repackaged for other threads a dizzying amount of times, be used in calculations for the game’s physics engine, which then produces graphics data shoved through a HUGE buffer to the GPU before that sends the appropriate electrical signals to 100,000 of nanoscale LED lights to shine into your retinas.
So yeah, it might suck a bit of power and it’s a fucking miracle that GNERATIONS of engineers around the world have contributed incalculable hours of their lives to ensure that your beat saber or goon session last just slightly longer than your stamina!
