The official unveiling of the iPhone 6S and 6S Plus is less than two weeks away. Apple has officially sent out invites for its big media event scheduled for September 9. Though a plethora of leaks over the past few months have revealed almost every major detail about the iPhone 6S and its bigger sibling, the latest leaks may disappoint a large number of users.

iPhone 6S To Have A  Smaller Battery And Thicker Chassis

Will iOS 9 help offer better battery life?

Chinese website CNBeta, which has a pretty good track record of revealing Apple product details ahead of their launch, has obtained the retail package of the iPhone 6S Plus. The publication reports that both the new devices will have a smaller battery compared to their predecessors. The iPhone 6S packs a 1715mAh battery as opposed to 1810mAh in the iPhone 6. The 6S Plus battery has also been reduced to 2750mAh from 2910mAh.

iPhone 6S To Have A  Smaller Battery And Thicker Chassis

Apple claims that the iOS 9 will be more battery efficient than iOS 8. The iPhone 6S and 6S Plus both pack more powerful hardware, so it’s unclear whether the new phones will at least match the battery life provided by last year’s iPhones. Meanwhile, MacRumors has learned from its sources that the iPhone 6S display panel is thicker and slightly heavier than that in the iPhone 6.

The iPhone 6S display assembly weighs 51.2 grams compared to 49.4 grams of the iPhone 6. Though the different is pretty small, Apple is trying to compensate for that by thinning out the back panel in the upcoming iPhones. The new iPhones are expected to use Series 7000 aluminum alloy, which is up to 60% sturdier than the Series 6000 material used in the iPhone 6. The new alloy should prevent a bendgate-like scenario.

iPhone 6S to have the same pricing structure

In yet another report, Dutch website TechTastic said the iPhone 6S will arrive in the Netherlands on Sept.25, a week after the device goes for sale in the United States. Sources told the Dutch publication that the iPhone 6S and 6S Plus will have the same pricing structure as last year’s flagship iPhones. That means Apple will not increase the base storage option from 16GB to 32GB. Those who want a higher storage will have to go for a 64GB or 128GB version or pay for the iCloud storage.

According to TechTastic, the iPhone 6S will cost €699, €799, and €899 for 16GB, 64GB and 128GB options. The 6S Plus will set you back by €799 for 16GB, €899 for 64GB and €999 for 128GB variant.
