The iPad Air2 from Apple brings about many improvements from its predecessor, the iPad Air.
To start with, the device is much lighter than the iPad Air. The iPad Air weighs 469 grams, while the iPad Air 2 weighs 437 grams.
The new iPad is a tad thinner than iPad Air.
It must have surely required a lot of hard work for the engineers of Apple to create the iPad Air 2, which is 6.1 mm thick as compared to the iPad air that was 7.5 mm thick.
The battery of the iPad Air 2 lasts much longer than that of the iPad Air, despite the fact that the iPad Air2 is much thinner than its predecessor.
The iPad Air2 delivers 10 hours of usage. The battery lasts longer because the Air 2 runs on the iOS8, which has amazing energy management capacities.
The iPad Air2 is faster than iPad Air as well, thanks to the A8X processing chip and its 2 GB RAM as compared to the iPad Air that has only 1 GB RAM.
The next gen iPad Air also has many improved camera features. It features an 8MP camera which is higher than the 5MP camera that the iPad Air has.
The iPad Air 2 also makes use of the Touch ID feature, that can be used to unlock the device and do online shopping and use it for the payments you make online. It ensures security of your device and your bank details remain safe.
If you are confused between what to use, the iPhone6 or the iPad Air 2, then you need to assess your requirements and proceed with it.
The devices both run on iOS8 and as a result of this, bear a lot of features that actually matter a lot.
If your requirements are concentrated more on browsing, playing, etc, you should choose the iPad Air 2. But if you are looking to use a device with most of these features as a phone, then the iPhone 6 Plus has to be your choice.
