One of the big questions surrounding Apple's expected iPhone 6: what size battery it will come with? An industry analyst believes it might be bigger than earlier rumors suggested.
The 4.7-inch model of the iPhone 6 could ship with a 2,100mAh capacity battery, rather than the 1,810mAh battery previously believed to be coming to the handset, news chief analyst at ESM-China Sung Chang Xu posted on Weibo this week. The analyst's claims are based on supply chain sources.
Reports have been swirling for months over what size battery will come in the rumored iPhone 6. The iPhone 5S comes with a 1,560mAh battery. In July, a report surfaced saying Apple's new handset could come with a 1,810mAh battery.
In general, bigger batteries have a greater capacity, which means a longer battery life for a device. However, the iPhone 6 is rumored to be coming with a bigger screen than its predecessors. Market watchers expect Apple to introduce two new iPhone 6 models with display sizes of 4.7 and 5.5 inches, though some recent reports speculate one device could be released at a later date. The iPhone 6 will also likely come with enhanced components that could put a drain on battery life. Whether a larger battery in the iPhone 6 will actually deliver better battery life remains to be seen.
Samsung, the biggest smartphone vendor in the world, has been actively targeting the iPhone's battery in recent ads. The ads show iPhone owners, or so-called "wall huggers," in airports forced to seek out power outlets and stay next to a wall while their phones charge. Samsung's Galaxy S5, the company argues, doesn't suffer from this power issue, due in large part to its 2,800mAh battery.
For its part, Apple has remained tight-lipped on its plans for new devices. Apple will reportedly hold a media event on September 9, where it is likely to launch the iPhone 6. Until then, all reports on the iPhone 6 are pure rumor and should be taken with a grain of salt. It seems likely that Apple's new iPhone could come with a higher-capacity battery, but until the device is announced, it's hard to know for sure.
