The iPhone 15 Pro prepares a very important change for the buttons of our phones. On the one hand, a button that has been available since the first iPhone will disappear, and on the other hand we will see a redesign whereby the buttons will no longer be just that, buttons.
The question before the haptic buttons is, what will happen when the iPhone is turned off? Well, they will still work. And they will do so thanks to a new ultra-low-power processor that will allow keystrokes to be detected, even if the iPhone no longer even has a battery.
A new chip in charge of the new buttons
The source of this information is on the MacRumors forums, where someone has written about the new ultra-low-power processor that will be used in the upcoming iPhone 15 Pro and Pro Max models. The novelty of this chip is that it will allow certain functions to remain operational even when the phone is off or the battery is completely discharged.
As MacRumors comments, the source had already shared correct data before the launch, so it is quite likely that this information is true. According to the source, the new microprocessor will take care of the current super low-power mode that allows locating an iPhone via the Find feature or using Apple Pay Express even if it has been turned off, or for up to 24 hours after the battery has been discharged.
The new chip will supposedly take over control of the Bluetooth and UWB connection, and will also power the capacitive buttons. That includes the new action button, so to speak, which replaces the mute button on the new iPhone models.
Apparently, in addition to the new button controller chip, Apple would be testing two methods to regulate the volume now that the two classic buttons have become one. According to the first method, touching up or down on the button would raise or lower the volume and, touching harder, the action would be performed faster. For the second method, we could slide our finger over the button to achieve the same effect.
We expect the rumored capacitive buttons to be exclusive to the iPhone 15 Pro and iPhone 15 Pro Max, with the standard iPhone 15 models retaining the same traditional button mechanism as on the iPhone 14 series – an important difference from the rest of the range that clearly has its own engineering challenges ahead.
The advantages, as we have already discussed on occasion, will be that with the new system, the iPhone will have fewer openings that need to be protected from water or dust entering the inside of the phone. At the same time, we will see greater resistance in the chassis itself, which could now be made of titanium, and we will also eliminate moving parts that, like all components of this kind, are susceptible to failure after a certain time of use or after a strong blow.
In any case, it should be emphasized that we are always talking about rumors. It is true that there are already several sources that speak of this change and it is also true that the move makes a lot of sense, but in any case, until we see the new features on stage at Apple Park, nothing can be taken for granted. While we wait for the disappearance of SIM cards in the iPhone, what is clear is that a few simple buttons will have much more technology behind them than it might seem at first glance.
