It seems like there’s more to the iPhone 6 than just bigger displays. Reports show that an added barometer sensor might make its way to the anticipated flagship which can be used to predict weather among other things.

A barometer is basically a sensor that measures altitude. It also collects air pressure data which can be used to predict temperature and weather information. With the possible integration of this sensor to the upcoming iPhone 6, we can see an additional feature targeted towards cyclists, hikers, and other active individuals that need an accurate weather report before setting foot out of the house. This will also go hand-in-hand with all the health-related trackers expected to come with the iOS 8.
9to5mac reports that they have discovered this possible feature on an iOS 8 code showing that it’s a new framework and will require a dedicated hardware. They tried testing the said framework with the current iPhone 5s to which it didn’t work, saying that the required hardware wasn’t found on the phone – this simply suggests that the hardware will only be available in upcoming devices.

Though we’ve seen barometers in other Android devices, it’s not a standard feature and isn’t fully utilized since there’s no continued support from third party developers. For iOS devices, there have been altitude-tracking apps which make use of its GPS and motion chips, but a dedicated barometer is quicker to load and provides more accuracy.
