Similar to previous releases, Apple never reveals the full spec sheet of its products, including during its press events as well as product webpages. However, thanks to Chinese regulatory agency TENAA, we do know now that the iPhone 6s and iPhone 6s Plus feature a 64-bit Dual-core processor clocked at 1.8GHz, which is 0.4GHz higher than last year's iPhone 6 and iPhone 6 Plus.
The iPhone 6s & 6s Plus are expected to launch in China starting September 25.
