The Samsung Chip used in iPhone 6S delivers less battery life than the one made by TSMC.
A new discussion has flooded the internet uncovering that not all iPhone 6S units get the same amount of battery life, because of the new A9 processor that has been built by both Samsung and TSMC.
Apple double sourced A9 generation from TSMC and Samsung. Keeping in mind that it was found earlier that the two chips are not of the same size, some early testing has uncovered that Samsung's A9 chip has a much more regrettable battery performance than TSMC's A9 processor.
The smaller Samsung A9 processors use a 14-nanometer processor while TSMC use a 16-nanometer processor.
One member of Reddit who has two iPhone 6S Pluses — one with a Samsung A9 processor and one with a TSMC processor — found that while you would anticipate that battery life will be better on the Samsung processor, the iPhones with a TSMC A9 chip gets up to two hours more battery life.
In view of some early tests, it creates the impression that about 70% of iPhone 6S Plus devices have a TSMC processor, while just 30% of iPhone 6S units have the Samsung A9 processor inside.
Apple's site asserts that iPhone 6S users can expect 14 hours of talk time on 3G, and up to 11 hours of video playback. Nonetheless it neglects to say that your battery experience could be drastically diverse in view of which processor you arbitrarily get.
However, if you want to know which chip your iPhone 6S is packing, you can download the free app Lirum Device Info Lite to discover which processor you’re packing.
