The iPhone 6 could have sensors to measure temperature, pressure and humidity, a freshly uncovered patent hints.
Apple has filed a patent for 'Electronic Devices With Environmental Sensors' that details plans for sensors that wouldn't be visible from the outside, but are installed in the same ports as the speakers or microphone.
They could also appear in Apple's much-rumoured iWatch, or iBand as it now seems it may be known.
Apple has also filed a patent for 'Electronic Devices With Temperature Sensors', which would involve building a thermal sensor most probably into the home button.
This could mean the iPhone 6 is able to measure the air temperature of your surroundings and give you a more accurate forecast than a dedicated weather service.
A temperature sensor built into the home button could also act as a personal thermometer.
Apple is going big on health – it recently hired a swathe of health professionals, prompting rumours that its iBand could be able to measure the wearer's blood- glucose levels.
It's also readying its Healthbook app, and reportedly working with Nike on the iBand fitness band.
Even if we don't see these features in the iPhone 6 or first-generation iBand, we could see them integrated into subsequent Apple devices.
