For the first time ever, Apple has dual-sourced the engine that drives the new handsets from more than one supplier. Both Samsung and rival Taiwan Semiconductor Manufacturing Company (TSMC) won contracts to build the Apple-designed 'A9' system-on-a-chip for the new iPhone 6s and iPhone 6s Plus.
While these chips offer literally the same compute and graphics power, both synthetic benchmarks and real-life tests have shown small yet notable difference in terms of battery as the TSCM-built A9 appears to be more power efficient than its Samsung counterpart.
The question is, does your brand spanking new iPhone 6s have the TSMC or Samsung-built chip? You can find that out in just a few simple steps, let me show you how.
