Without a doubt, the TouchID was the biggest and most exciting news of the day. But the centralization of all the information provided by the accelerometer, compass and gyroscope in a separate processor is plain genius for two reasons: first, because having a separate chip registering all these inputs will provide continuous, much more precise information much faster. And second because this is accomplished without any need for extra battery.
In fact, this will help spare battery, as the M7 will identify when the user is asleep (taking into account long periods of time when the phone has been left untouched) and will tell the iPhone to access the internet less often in this meantime.
The M7 isn’t just one of the best systems for fitness and health apps such as the Nike+, for instance. Its use will be an excellent trial for future implementation in the so-called wearable devices which a few companies have introduced in a pretty messy way.
I bet that Samsung is pretty pissed about not having thought of something like that for their watch, which has a battery that lasts for about a day. I would never buy a watch that needs to be recharged every single day, and I’m pretty sure that I’m not alone here. But I’m pretty sure that starting today they will start working on something similar to the M7 for their second generation watch.
This processor is exactly the piece that was missing for this market of wearable devices such as bracelets and watches. And soon millions of iPhone users will be testing it out across the planet, helping this technology get even better in no-time.
