The controllers last a really long time on a single battery. My Quest 2’s batteries are finally getting low and I bought it six months ago.

These use integrated batteries and does full on inside out tracking on each controller, each controller having its own snapdragon 662.

They also do not list how long the controllers last, not found any source mentioning that yet, which is a huge red flag.

Plus, they are just a single AA in each controller. Swapping takes like 30 seconds. I use NiMH rechargeables and just swap between a couple of pairs of them whenever necessary.
