Apple Says Vision Pro Performance Could Be Reduced in Some Situations

Like the iPhone, the Vision Pro has an always-on battery management system that could lead to reduced performance in certain situations, according to Apple.

In a support document published today, Apple said Vision Pro users could notice impacts such as longer app launch times, lower frame rates, reduced wireless speeds, screen dimming, or lower speaker volume in situations where the Vision Pro is low on battery, has a chemically aged battery, or is in a peak-power state.

Apple's full explanation:
Apple Vision Pro has built-in software and hardware systems that help reduce performance impacts that may be noticed in certain conditions such as a battery with a low state of charge, a high peak power situation, or a chemically aged battery. The system is automatic, always-on, and works to provide the best possible performance. Power needs are dynamically monitored, and performance is managed to address these needs in real time. The system allows Apple Vision Pro to balance and reduce performance impacts as much as possible. The user may or may not notice effects on device, which may be temporary. Depending on the device battery state and the tasks that your Apple Vision Pro is handling, some examples of these effects may include longer app launch times, lower frame rates, reduced wireless data throughput, screen dimming, or lower speaker volume.

Apple introduced a similar system on older iPhone models back in 2017, but it failed to mention the system in its iOS release notes at the time, leading to a major controversy. Apple eventually agreed to pay up to $500 million to settle a class action lawsuit that accused the company of "secretly throttling" some iPhone models.

Nowadays, the system is considered by many to be a helpful feature that ensures smooth performance and prevents unexpected shutdowns.

This makes sense on a device that is burning so much power so quickly. 36Wh in 2 hours is an average of 18W. This thing probably peaks close to 50W if I had to guess. In general, the faster you pull current from a battery, the deeper the voltage will dip. As future chips and sensor circuits become more efficient, battery life will increase and this issue will become less pronounced.

This is boilerplate, sure. On the bright side, unlike, say, an iPhone or a Mac, Apple is selling extra batteries direct to consumers, and they can be replaced. Rare benefit of the cable situation.

Not to mention the rare Lightning Pro Plug...

This is exactly what I was thinking, and it's not at all related to slowing processor performance when the battery ages like the article suggests. It's more that under certain conditions (high loads, low battery), performance may degrade because there's not enough power being supplied to do everything at 100% all at once.

This is clearly just obligatory boilerplate after the batterygate silliness, but "lower frame rates" would be disastrous for a headset.

The game fries your retina. This cannot be good for the eyes. Even the iPhone has a warning now saying your looking st the screen too close and should be an arm away. How is this even allowed? The device even overheats during overextended use according to reviewers.
 
  • Wow

"We made technical decisions with information you cannot possibly have and tradeoffs you cannot understand but we have to tell you so the few who notice (usually using special hardware) dont sue us for another $500 millions...you morons"

"ChatGTP what's the difference between heats up and overheats?"
