The sizes of the iPhone 7 and iPhone 7 Plus batteries have finally been revealed thanks to leaked data from the FCC’s Chinese counterpart, TENAA. The leaked info appears to confirm that the new batteries will give the handsets longer battery life than their predecessors.

On Monday, TENAA reportedly published the specifications of the new iPhones on its Chinese website, and TechnoBuffalo found out that the iPhone 7 houses a 1960 mAh battery, while the iPhone 7 Plus comes with a 2900 mAh battery.

Compared with their predecessors’ batteries, the new handsets have larger power capacities. The iPhone 7 gets a big boost from the 1715 mAh battery of the iPhone 6s. On the other hand, the iPhone 7 Plus, which is the more premium offering between the two, only comes with an extra 150 mAh compared with the 2750 mAh battery of the iPhone 6s Plus.

GSM Arena calls the capacity increase in the iPhone 7 Plus battery modest, but it still pointed out that it’s not as remarkable as the significant jump in battery size of the iPhone 7.

With longevity issues being the pet-peeve of loyal iPhone users, the minimal boost in the iPhone 7 Plus battery could still perpetuate the same issues. Furthermore, GSM Arena points out that the new chipset and the brighter screen will certainly influence battery life, but it’s still too early to tell how the new batteries would do on average use.

TechnoBuffalo has learned that Apple is claiming that the iPhone 7 can run two hours longer than the 6s, while the 7 Plus can go an hour longer than its predecessor, which is what can be expected from the difference in their capacity increments.

Apple Insider claims that Apple has been reluctant to market the battery sizes of its mobile devices because it prefers to bank on the number of hours its products are capable of running under certain circumstances.

What Apple is promising now, though, is that its new iPhone 7 and iPhone 7 Plus have the longest battery lives in the history of iPhones because of their quad-core A10 processor that has two cores designed mainly for power consumption regulation.
