Which is longer battery duration for Samsung vs TSMC made A9 chip of iPhone 6s?

It is known that the A9 chip, which is a new SoC installed in the iPhone 6s / 6s Plus, is manufactured with two companies, Samsung and TSMC, and the A9 chip of the purchased iPhone 6s / 6s Plus is the manufacturer Is it made?Application to checkHas also appeared. Apple said "There is no big difference between the companies' chips"Ars Technica actually used iPhone 6s with two A9 chips to test the difference in battery duration tested with" Wi-Fi browsing "" WebGL "" Geekbench 3 "" GFXBench " We are comparing and verifying.

Samsung vs. TSMC: Comparing the battery life of two Apple A9s | ​​Ars Technica

America's leading news media · Ars Technica has prepared a new iPhone 6s with Samsung and TSMC A9 chips. Both are American communication carriers · AT & T's SIM lock version, but since there was only one SIM card, all test communication was limited to Wi-Fi only. Both of the screen brightness were set to 200 nits, and it was set up so that the screen did not turn off automatically during the test, and it was compared and verified whether there is a difference in the battery duration.

Below is a graph summarizing the results of the test, red means Samsung and blue means TSMC, meaning that the higher the value, the longer the battery life. In the tests of "Wi-Fi browsing", "WebGL" and "GFXBench", there is no big difference between the two companies' chips and it is within the error range of 2 to 3%, but only for the test of "Geekbench 3" TSMC's A9 chip resulted in a 28% longer battery life time.


Each item has been tested twice, and it is the average value of the results of testing three times only "Geekbench 3" which was big difference. When using the Xcode tool "Activity Monitor" that can investigate CPU load of iOS terminal, 3D iOS application "Shooty Skies"Is displayed, the CPU load ratio is 30 to 70%, and the load factor of the CPU under test of" Geekbench 3 "was 60% in total. Based on these test results, Ars Technica says that the performance of the A9 chips of both companies may differ only when playing 3D games that intensively load CPUs and GPUs.

However, except for 3D games, there are not many behaviors that intensively load CPUs and GPUs on iPhone 6s, so it seems that the battery duration of both companies' chips is almost unchanged. Also, the test results other than "Geekbench 3" apply to the performance difference "2 - 3%" released by Apple the other day. Reddit · Apple's fan site · Geekbench database etc. also have test results, and there is a possibility that the performance difference of both companies' chips may change due to changes in the result of test results in the future. Because manufacturers may also improve the manufacturing process of A9 chips, Ars Technica who tested "There will be no big difference to worry, no matter which A9 chip made by Samsung or TSMC" I have concluded.
