iPhone 6: Almost Double the Battery Capacity of the iPhone 5s



The iPhone 6 may last almost twice as long as the iPhone 5s on a single charge thanks to a gigantic battery and improved power management in iOS 8.  A video is making the rounds that shows the 2,915 mAh battery that will reportedly power the larger of the two models Apple will likely introduce tomorrow.

Until now, Apples introduced one flagship iPhone model per year. The company typically rehashes older models to satisfy those on tighter budgets, but hasn’t really offered people much choice, besides carrier and storage capacity. For the first time, Apple will introduce two new iPhones with different screen sizes and specs at its event tomorrow and if you want to maximize battery life you’ll want to get the lar5.5″ iPhone 6 rather than the rumored 4.7″ model, which will have a smaller battery.

Above is the video of the leaked 5.5″ iPhone 6, which Nowhereelse.fr posted. As the video description and previous iPhone 6 rumors note, the larger device may be called the iPhone 6 Air, iPhone 6 Pro or something similar. The video shows an Apple part number, but of course is not officially confirmed.

Like with all large smartphones, the 5.5″ iPhone 6’s display will require more power, but the larger battery will likely net longer real-world battery performance. Those who keep their iPhones on standby for long stretches will realize the biggest battery benefit from opting for the 5.5″ iPhone 6 rather than the smaller 4.7″ model.

Many phone manufacturers  are already packing large batteries into large smartphones, blowing away the iPhone 5s‘s 1,560 mAh. For example the Samsung Galaxy Note 4 has a 3,300 mAh battery and the LG G3 has a 3,300 mAh battery.



A bigger battery alone doesn’t guarantee great battery life however. Fortunately, iOS 8 will provide detailed reports on which apps are too power thirsty so users can kill them when they need to eek out a few more hours of juice. As you can see, this is a lot more information that what’s currently provided in iOS 7. You can read more about the differences between iOS 7 and iOS 8 here.

Apple Battery Life Compared

Apple has a habit of selling battery life as key differentiators between its own product lines.  For example, it advertises its 13″ MacBook Air with up to 12 hours of battery life and the smaller 11″ MacBook Air as having 9 hours of battery life. The three hours of extra battery life is key for many users, including mobile professionals and one reason why Apple is able to charge a $100 premium for the larger computer.  We expect Apple to charge a similar premium for the 5.5″ iPhone 6. While the larger display will be the primary selling point, longer battery life will be the biggest advantage in real-world use.

    Of couse it is the duration of a charge in normal use, rather than capacity, that is the biggest issue. While. this is clearly a function of capacity, we all know that there are many other variables. The advantage of capacity over duration as a metric is that it is more easily specified.

    This really isn’t the first time apple has released 2 phone models in a year. Last year apple released the 5S alongside the 5C model. This was a break from their typical style of releasing 1 model and offering older models for value minded shoppers. The trouble was the 5C was inferior compared to the 5S and the price difference didn’t offer those who were considering a 5C enough of a value to sway them in its direction. This year, they appear to be adding a phablet style alternative without alienating their traditionalist base. I think this is a much better approach.
