Meta says that the Meta Quest Pro handle battery life is "up to 8 hours".
Twitter and Reddit have rumors claiming that the Touch Pro handle, like the headset, has only 1-2 hours of battery life, which will seriously hinder Quest Pro availability, because while the headset can be used with a portable battery via USB-C, the handle can only be wirelessly charged via the included dock or the portable charger for sale separately.

Meta does not list the battery life of the handle on its specification sheet. A representative responded that the expected "up to" 8 hours and reminded that "the battery life of the handle may vary depending on the conditions of use and the content of the operation." Typically, applications running a lot of haptic feedback will run out of the handle faster.
famous programmer and Meta "advisor CTO" John Carmack said that he had not encountered a low battery warning for four hours using the Quest Pro handle. Meta CTO Andrew Bosworth also said, "I have never exhausted the Quest Pro handle. I have used it for a long time in the past few months." Unlike other VR all-in-one handles, the Touch Pro handle has self-tracking function, with three cameras and an onboard chipset, which means that tracking can be performed at any angle no matter where the headset is facing. Not only that, the Touch Pro controller also has "new localization and VCM haptic upgrades", which Meta says provides "a broader and more precise range of feedback" compared to the Quest 2 controller. The
Touch Pro is included in the Quest Pro box, but it can also be purchased separately for $300 later this year and is compatible with Quest 2.
