TSMC is the company that will produce the latest Apple A12 chip processors. According to sources, Apple A12 uses 7nm chip designs directly to ~ 20% faster and 40% reduction in power.
The A12 chip will also have faster and more efficient thrusts if multi-core use is used. Because the Apple chip rarely works in multi-core modes (only in certain situations), so the performance of the A12 chip will have only 20% -30% improvement.
Meanwhile, the live-screen (SOT) on the new iPhone is dependent on each model, battery capacity, screen, and modem used. According to sources, what is definitely the battery endurance time if the iPhone is not used is amazing.
In just a few weeks Apple will introduce a new iPhone. So, to know the real thing about Apple's performance and battery - we're looking forward to it.
