Several weeks following the official unveiling of the iPhone 6s and 6s Plus, we discovered out that Apple’s newest smart-phone couple had been sent with two versions of the recent Apple-developed A-9 SoC – one made by samsung.com using the 14nm procedure and another by TSMC based to the 16nm manufacturing node.
Naturally, this advice compelled involved consumers to discuss standard evaluations while one programmer even set together a crowd sourcing program called CPU Identifier to assist consumers determine the A-9 processor variation on their iPhones, making a running data base of models including TSMC processors versus those sent using the Samsung A-9 SoC. To the reduction of iPhone 6s and 6s Plus owners, first standards didn’t demonstrate an important difference between operation on both processors.
Nevertheless, rsquo the narrative doesn&;t end there, it appears. New findings show the Samsung A9 processor could have drawn the short straw in regards to battery life. According to one Reddit person remarking under a related place, the TSMC variation might supply to to 2 entire hours of additional run time compared to its Samsung equivalent. The inference comes from a Geekbench battery check the redditor ran on 2 identically set iPhone 6s up Plus models, one with the Samsung A-9 and the other with a TSMC processor.
Ran this evaluation outcomes and a few times were not inconsistent. Consistently about a 2 hour variation in length. Both telephone numbers were analyzed using the exact same backup, same settings. Additionally attempted analyzing them as outcomes and phones were not dissimilar.
You’d believe the smaller processor will be more effective but the standards don’t actually represent that.
Following are the outcome of the evaluation:

That’s an approximate 20% variation and only the TSMC processor, which comes as a surprise, since samsung.com’s 14nm FinFET should be less power greedy compared to the TSMC’s 16nm node. Not only that, small design of the former should decrease heat output signal, however, if the information relayed from the OP of these Reddit post is something to go-by, it appears to be jumping out on that advantage at the same time. The post estimates several evaluations across two posts by Chinese web site MyDrivers displaying the TSMC with well more battery existence and a working temperature of 37.4°C versus 40.5°C on the Samsung A-9 processor.

In one post, the Chinese web site shows equally A-9 forms subjected to movie play back and Java Script rendering evaluations while still another post compares the two against each other through 1 2 AnTuTu Standard runs, with the former resulting in a approximate 8% closing difference between battery usage and only TSMC and the latter, about 26% from the finish, again, and only the TSMC A-9 processor.

The best way to check which processor is in your phone?
In light of the findings that are surprising, we wouldn’t blame you if you are nervous to be aware of the make s A-9 processor. If you’re trying to find a good approach to do that (besides the aforementioned CPU Identifier), it is possible to download Lirum Device data Lite to your iPhone from here. The app will let you know the version number. For the iPhone 6s, version N71AP includes the Samsung A9 processor while N71MAP provides the the TSMC form. For the iPhone 6s Plus, the Samsung version is N66AP and its TSMC counterpart goes by N66MAP.
