Will the next model of the iPhone have a larger display? Recent rumors from the supply chain seem to indicate so. Specifically, the reports claim that instead of the current 3.5 inch display, the new iPhone will have a 4.08-inch screen. The current resolution of 640 x 960 pixels will also increase to 1136 x 640. Meanwhile, the aspect ratio of 4:3 will be moved up to 16:9. Pixel density and brightness will be slightly decreased however. The current pixel density is ~320 ppi, which will be changed to ~320 ppi, while the 569-nit brightness will be reduced to 500 nits.
To date, this would be the most radical change that Apple is doing for the iPhone, if it indeed happens. The iPhone has been altered very little from its first iteration, the iPhone to the latest, the iPhone 4S. Mostly, the changes involved hardware upgrades and minor design tweaks.
Now, if Apple pushes through with the screen enlargement, this change will most probably meet some resistance. On devices with larger screens, the most common gripe is that the battery life gets drained fast since the battery has to power a larger screen. They also complain that it is difficult to handle the device with one hand as easily as it takes to do the same on a smaller device. However, since Apple is not making the device as large as other handsets out there, it may be able to elude these complaints.
The battery life, however, might pose a problem. At present, the iPhone 4S is powered by a 1420mAh battery. Meanwhile, the iPhone 5 is speculated to have a ~1400mAh battery. These figures fall short especially when compared with other devices that have been recently released by Apple’s rivals. The Samsung Galaxy S III, for instance, has a 2100mAh battery, which powers its 4.7-inch screen. The HTC Evo 4G LTE, for its part has a 2000mAh battery, while the Droid Razr Maxx contains a 3300mAh battery. If the iPhone 5, however, will implement the change in size, and more importantly, if it throws in a 4G LTE radio, it will definitely need to increase its battery capacity.
Apple has made no comment regarding these speculations, preferring as always, for rumors about its new device to emerge from the information-hungry public.
