A new iPhone, a new “gate”. Apple uses two different chips in the new iPhones. Battery life depends on the chip.
The new iPhones have been out for a while now and we are hearing a lot of complaints. Some say that the device is turning off unexpectedly and Apple has already started replacing those units. Now two great YouTubers have revealed the chipgate.
Austin Evans and Jonathan Morrison just uploaded YouTube videos explaining the chipgate. As it turns out, Apple is using two different chips in their new iPhones, one made by TSMC and one by Samsung. The TSMC one uses 16nm process and is physically larger than the 14nm Samsung chip. As we should all know, the smaller manufacturing process should improve the power efficiency. Now it looks like the Samsung chip is actually using more battery.
The videos are linked below but the main thing is that the iPhone running Samsung chip has slightly worse battery life. In worst case scenario, a synthetic benchmark, the TSMC iPhone lasted almost 50% longer than the Samsung one. In real life, the difference is way smaller but still noticeable. CPU performance is almost equal, Samsung losing by a few percent in multi core test in synthetic benchmarks but matching the TSMC one in real world test.
There’s an easy way to check which chip your iPhone 6s or 6s Plus is running. A free app called Lirum Device Info Lite – System Monitor shows the model number of the iPhone. IPhone 6s with model number N71AP is running Samsung chip as the N71MAP has a TSMC chip. N66AP 6s Plus is the Samsung one and the N66MAP uses the TSMC chip. This might be useful information if Apple decides to replace the units with worse battery life.
It remains to be seen, how Apple reacts to the chipgate and what is the real cause of the worse battery life. Usually the smaller manufacturing process means better battery life but in this case it doesn’t. Is there some optimization issues by Apple or is this Samsung’s fault? Can the problem be fixed via a software update or is replacing the unit the only way? Hopefully we will hear more soon.
