iPhone 6 reports to date have all revealed Apple’s 2014 smartphones will be even slimmer than predecessors, which obviously means their batteries will have to be thinner – in fact, one report from suppliers familiar with the matter suggested that Apple may have had some troubles shrinking down the battery of the bigger 5.5-inch model to desired size, an issue that could cause shipping delays. While most iPhone 6 reports did not detail battery capacity, a new report from Asia shares more details about the supposed battery sizes for both the 4.7-inch and 5.5-inch versions.

According to digi.it.sohu.com, the 4.7-inch iPhone 6 will have a battery capacity of between 1,800 mAh and 1,900 mAh, while the bigger 5.5-inch iPhone 6 will pack a 2,500 mAh battery.

A report from early February also said the 4.7-inch iPhone will have a 1,800 mAh battery, without detailing the iPhone 6 phablet’s battery capacity.

Even though both rumored batteries are bigger than the battery found inside the iPhone 5s and iPhone 5c, it’s not clear whether they’ll be able to offer even battery life, considering that Apple’s 2014 iPhones will have bigger displays and, thus, heftier power requirements.

To maximize battery life, Apple could introduce various software tricks, although the company has yet to uncover them. Various Android smartphone makers including Samsung, HTC and LG have devised ways to improve battery life in 2014 devices, and Google plans to improve battery life with Android L as well.

For comparison purposes, the Moto X and HTC One (M7), both 4.7-inch devices, have 2,200mAh and 2,300 mAh batteries, respectively. The Galaxy Note 3 and LG G3, both 5.5-inch devices, have 3,200 mAh and 3,000 mAh batteries, respectively.

Samsung has recently made a point of the iPhone’s smaller battery capacity, by releasing a new ad, which mocks Apple’s smartphone, calling its owners “wall-huggers.”
