New Charging Sound Discovered in iOS 11, Perhaps for iPhone 8 Inductive Wireless Charging Functionality

    Buried in iOS 11, there seems to be a new sound file that could potentially be implemented when the rumored "iPhone 8" is released with inductive wireless charging capabilities. Highlighted on YouTube, the sound file is called "engage_power.caf," and it is distinct from the existing "connect_power.caf" sound file that's used whenever an iPhone is connected to a Lightning cable.

    In the video below, the unused charging sound is compared to the existing charging sound in iOS 11. The new audio file provides a longer, more distinct sound that could perhaps be used to assure iPhone users that their devices are properly charging should the iPhone 8 indeed include an inductive-based wireless charging function as has been rumored.

    While both the name of the file and the sound seem to indicate that it is related to some kind of charging purpose, there's no way to confirm why the sound has been added, so this is all pure speculation at this point.

    In fact, there are several other sound files in iOS 10 and 11 that are unused and do not have a purpose, so it's not entirely clear if the new charging sound will actually be added to the iOS 11 operating system or what it will be used for. The hidden sound file in iOS 11 is not accessible on a device running iOS 11 and must be accessed using a computer.

    Wireless charging is expected to be included in the radically redesigned "iPhone 8" coming in the fall of 2017, and perhaps its two companion devices (presumably the iPhone 7s and the iPhone 7s Plus), but there's still some question about the form the wireless charging functionality will take.

    Early 2017 iPhone rumors suggested Apple was aiming to implement long-range wireless charging, perhaps through a partnership with a company like Energous, but that technology may not be advanced enough to be used in the iPhone. Long-range wireless charging continues to suffer from problems like object interference and much slower charging rates as the distance between the receiver and the transmitter increases.

    Apple is no doubt working on long-range wireless charging, but recent information suggests a simpler solution will be added to the iPhone 8 - inductive charging. An inductive charging solution, which is what's used for the Apple Watch, would require the iPhone to attach to some kind of charging puck, mat, dock, or other device. It would perhaps be simpler than a Lightning port, but it isn't a full wire-free contactless solution.


    Regardless of how wireless charging is implemented, there's overwhelming evidence that this is a technology Apple is aggressively pursuing. Apple joined the Wireless Power Consortium in February, hired dozens of employees with expertise in wireless charging, and has sourced wireless charging components from a range of manufacturers including Lite-On Semiconductor, MediaTek, and Luxshare.

    Wireless charging is looking promising for iPhone 8 then.:cool:

    Love little leaks like these. These next few months are going to be exciting.

    At this point iPhone 8 looks very promising. Apple is late with wireless charging, so I'm hoping that means it will be refined and better than the competing solutions. Only time will tell if that is the case.

    Pure speculation at this point, but I'm guessing that they're going to try to find a way to make the Apple Watch and iPhone inductive chargers interchangeable.

    Its definitely different. It makes me think of how the lock screen and keyboard click changed the overall sound with iOS 10. It's the small features that make a difference in what we have been used to hearing for so long.

    It's ridiculous how a silly little noise buried in an operating system can make anybody so excited.

    That said, this silly little noise has made me super excited. :oops:

    I was hoping for Ash from The Walking Dead saying, "Groovy", to be used as the sound but I will reluctantly accept this.

    Haha, that was a great sound. It's going to sound great with the iPhone 8 speakers.

    It sounds like it would work for inductive charging. The sound gets fuller towards the middle and then quieter at the end, like a bell curve or a pulse.

    Considering how if you don't want to get the Air Pods, you have to pick between listening to music via headphones or charging... I'll even take the mat inductive charging. Thanks Tim.

    Two things: 1. That is definitely a sound. My ears confirmed it. 2. Picture of AW and charger are too small. Can't really see it.:D

    Even if it's nothing, it's a pretty exciting find! I hope some other potential iPhone 8 hints pop up.

    I don't know bud. I'm not in the tin foil club, but the idea of wirelessly charging the AirPods while they're in my ears:eek:
    JK. The AirPods charge so quickly it's hardly relevant.

    How would wireless charging work if you have a case on your phone??

    What a great discovery! That would be the only reason for a different sound, especially one named 'engage power'.

    Totally hyped up over the upcoming iPhone.
    So much for keeping low expectations, haha but honestly my gut tells me Apple will deliver something amazing this year! :D
