The iPhone 6 and iPhone 6 Plus have displays that are larger, brighter, and with better quality than anything we've seen from Apple so far. They also have a 25% faster CPU, and 50% faster graphics. All that jazz must take a heavy toll on the battery, right? Wrong - due to the 20nm production method for the A8 chipset, and the new, more efficient chip packaging, the alleged 2915 mAh battery of the 6 Plus, and the 1810 mAh juicer of the iPhone 6 can last a long time. As you can see, the iPhone 6 and 6 Plus are both crossing the 10-hour of screen-on time while watching videos or browsing, which is an excellent achievement, but we will run our own test to compare those to what the current flagships can muster.
