Recently, a controversy surfaced about the battery life of iPhone 6S and iPhone 6S Plus because some of these models have Samsung A9 processor chip and some come with TSMC chip and some people claim both differ in battery performance.
Apple Inc uses parts of multiple manufacturers to meet the requirement of its products.
According to this controversy, TSMC A9 chip-gate is more efficient than that of Samsung’s chip that drastically reduces the battery life.
Apple has categorically stated that the two different chips used in iPhone 6 and iPhone 6s models that these were tested numerous times and the difference falls between 2-3% range and the controversy-mongers propagated that the Samsung chip consumes battery quite differently.
The benchmark test results prove that TSMC chip’s performance is slightly better than Samsung’s chip and validates Apple claim that the variation in battery life ranges from 2-3%
The tests also shows that most of the time battery timing of iPhone 6s and iPhone 6s Plus remains same irrespective of which chip your phone has, except in scenarios like Geekbench 3 that requires power-hungry performance.
So now this overblown debacle must end once for all as Apple did not cheat its users and it came out clear in the end. It is pertinent to mention here that the parts sourced from multiple manufacturers will certainly perform a little differently, but as long as the differences are small, customers don’t care about it.
