In early October, enthusiasts, tested two iPhone 6s, came to the conclusion that the smartphone chip A9 production TSMC under similar loads lasts longer than the same smartphone, but with Samsung CPU .
Apple has denied the existence of problem, claiming that the difference in battery life does not exceed 2-3%, which is within normal limits. The same opinion is shared by experts Consumer Reports, which conducted a series of tests and found the problem described above. The test involved two iPhone 6s A9 processor production TSMC (model N71mAP) and Samsung (model N71AP) on the platform iOS 9.0.2. Both smartphones are "tied" to the mobile operator T-Mobile. As a result, the difference between the two tests did not exceed 1-2%,.
Note that Samsung manufactures processors A9 at 14-nanometer process technology, while TSMC in their production uses 16-nanometer rules.
