Independent reviews saying that two types of iPhone 6s processors have different battery power are concerning current users. Apple worked with two companies to produce its recent A9 processor, and this decision is already creating controversy.
As tech professionals initially revealed, iPhone’s manufacturers have two versions of CPU in their recently launched smart phones. The first one is a compact sized processor created by Samsung, while the second one is a little bigger chip produced by TSMC. Samsung’s system is based on the 14-nanometer model and TSMC’s device is created following the 16-nanometer design.
Apple used a dual-sourcing strategy, especially for the chip designing part, and released its smart phones with major battery problems. For price and energy reasons, the company has no reasons to integrate little chips, unless the small sized processors were not available in the right amounts. Experts stated, based on battery power analysis performed in Chinese labs, that a TSMC processor has 20% more battery power than a Samsung chip.
The line between TSMC ans Samsung systems is not very clear, the number varying between 20% and 50% difference in battery life. The Lirum System app apparently tells you what type of processor you have on your iPhone 6s or 6s Plus, even if neither that application nor the iStat provide constant values in repetitive tests.
Regarding this problem, Apple released a statement saying that certain manufactured laboratory assessments run its devices with continuous heavy loading. These tests are not finished not until all battery power is depleted and do not represent real-world utilization. Their poor results are caused by the fact that phones spend a long period running at maximum CPU performance.
The company’s officials added that this is a misleading method to measure real battery power. Apple’s tests and user data proved that the real power of the iPhone 6s line, even considering different element differences, vary within only a 3% range.
The problem of iPhone users comes from the gadgets’ relatively short battery power. Apple always preferred an extremely slim design over a thicker and more durable battery, and this was exactly the main issue about the past iPhone. Recent iPhones’ batteries do not last as long as their predecessors, but this is a problem met in many flagship gadgets, partly caused by their energy-draining top performances.
Battery power examination is also very hard, because there are countless methods that people use for their gadgets. They can analyze gadgets using ongoing LTE video loading, for example. That method really pushes the audio and display capabilities to the max, but does not stress the processor too much.
Other tests conducted by 6S customers came to identical conclusions: this difference was less noticeable when they were using processes that were not regularly straining the CPU. Even then, devices with a Samsung processor seem to be a little less performing than mobile iPhones with a TSMC-produced chip.
Apple out sources several of its iPhone elements from a number of companies, not just processors, which makes it hard to look for similar factors in these assessments. People also used an iPhone 6S with a TSMC processor and one based on the Samsung system to perform their own evaluation regarding other factors. Here are included essential features of any smart phone, like mobile connection and display lighting. Minor differences have been noticed during these preliminary tests, too
A more power-efficient device and display could make an important difference in user’s analysis than power-efficient processors. Geekbench pushes CPUs in tests that are not completely realistic. For instance, Apple performs its devices’ evaluation with the display lighting at the lowest level. In conclusion, producers and users alike might both be right, only in different circumstances.
