iPad 3 Battery Life – 10 Hour Target:
There would appear to be a magic figure that Apple want all iPads to be able to deliver and that is 10 hours use of their tablets on a single charge.
So how do you ensure that this desirable 10 hour figure stays the same when the new version of the iPad will offer 4G LTE (a notorious battery drainer) and a densely packed 3 million pixel high definition screen consuming power via quad core graphics processing?
One answer would obviously be to put in a bigger battery, but when you have got a product that is selling like hotcakes and has no reason to reinvent itself, why on earth would you redesign a winning formula to accommodate a bigger battery. Even though the new iPad is heavier and slightly larger it is hardly a full redesign.
The other would be to reduce the overall power consumption by redesigning the chip architecture.
New battery technology ensures great performance:
But the answer for Apple has come from working on the battery itself and this has resulted in an iPad 3 battery that has nearly double the capacity of the iPad 2 battery meaning you get a whipping 42Wh in teh iPad 3 compared to to only 25Wh in the iPad 2 which from my tests on wi-fi and general use is hardly a poor battery anyway.
This when measured in milliamps means that the new iPad 3 will offer 11,666 mAh compared to the iPad 2’s 6944 mAh, so almost double.
But, like we have mentioned prior, the iPad 2 is considerably less power hungry on the screen side and also with the 4G LTE option that the new iPad 3 will offer, so Apple had to do something.
So what is going on in this battery to make it so powerful without the associated weight and size growth that it would seem to need?
Apple battery labs are hard at work:
Until we see the final product and get some wise ass to do a “teardown” we can not fully say, but, it appears that Apple’s battery laboratories have been hard at work testing new technology and improving the power of their Li-ion cells, and with the battery world in serious need of a catch up to keep up with new mobile technology that is so power hungry, could Apple have found more technology with which to sue every other company who tries to take a bite.
Are you happy with your iPad battery life currently and how do you think they will manage to pull this off when the new device will be so power hungry?
