The internal specifications of the iPad Pro are beginning to appear despite the fact that it is not yet available to buy nor have the first explorations of iFixit been done. To its A9X processor we have to add 4GB of RAM, double that of its smaller brothers, the iPad Air 2 and Mini 4, and which give it a raw power that many current laptops would like. And the battery? A device of this size and with this screen must have a monstrous battery to be able to achieve the 10 hours of autonomy that Apple promises. But the reality is that its battery is smaller than that of the iPad 3 and 4, and only slightly larger than that of the iPad Air and Air 2.
The iPad Pro has a 38.5 WHr battery of the same type as its predecessors, and in the box we find the classic 12W iPad charger. Let's compare this battery with that of all the iPad models that have existed so far:
- iPad - 24.8 WHr
- iPad 2 - 25 WHr
- iPad 3 - 42.5 WHr
- iPad 4 - 43 Whr
- iPad Air - 32.4 WHr
- iPad Air 2 - 27.3WHr
- iPad mini - 16.3 WHr
- iPad mini 2 - 24.3 WHr
- iPad mini 3 - 23.8 WHr
- iPad mini 4 - 19.1WHr
As you can see, the iPad Pro is located between the iPad Air and the iPad 3 and 4. How is it possible that an iPad with that screen and that power can have a smaller battery than the old iPad 3 and 4, smaller and much less powerful? The explanation is very simple: while batteries have been stagnant for years without major improvements that increase their life, screens and processors have managed to reduce their consumption to figures impossible to imagine just a few years ago. In this way, we achieve that a much more powerful device, with a higher resolution and a larger screen, consumes less than an older one with worse specifications.
Could Apple have given the iPad Pro more battery? Ten hours of autonomy seems enough for a day of work, but it never hurts to have more hours of battery available. This statement seems logical and surely many of you think so. But what seems like something negative in the end goes to the benefit of those who buy the device, because having that battery and not a much larger one, they have achieved, on the one hand, that the chargers that already exist continue to serve, and also that the charging time does not increase. If the iPad 3 and 4 took about 5 hours to fully charge with the official charger, this iPad Pro should be fully charged in a little less time.
This same reasoning can be used to do something more reasonable to reduce the size of the batteries in the new iPhone 6S and iPhone 6S Plus and that is already costing you criticism. The entry of new components on the plates have been able to force this reduction but in parallel it could be that this reduction was not noticed with respect to the iPhone 6 and iPhone 6 Plus equipment.
Time will have to be given.
According to Apple the battery life is the same, and in those things it does not usually deceive.
