Processor
The iPhone 5s uses the A7 chip, which runs twice as fast as the A6 chip. It was the first generation in 2007 40 times that of the iPhone ARM11 chip. The 64-bit architecture of the A7 chip supports OpenGL ES version 3.0.
The iPhone 5s uses the M7 coprocessor, which offloads the workload on the A7 chip by collecting data from the accelerometer, gyroscope, and compass. The M7 co-processor continuously measures the user's movement data and saves battery life for pedometers or other fitness apps that use accelerometers throughout the day.
iPhone 5s GFlops value is 76.8.
Touch ID
iPhone 5s adds the fingerprint recognition security function “Touch ID”. Touch the home button, and the user's fingerprint will be automatically recognized and unlocked in 5 seconds. Touch ID can be used to purchase App Store applications. The HOME button is made of sapphire glass, and the stainless steel ring on the button can detect finger contact and transmit the user's fingerprint to the sensor through the HOME button. The more times the fingerprint is read, the more accurate the fingerprint recognition will be. "Touch ID" also supports multiple fingerprints. The user's fingerprint information is all encrypted and stored in the A7 chip and will not be transmitted to Apple or iCloud, and other software has no right to access it.
Camera
iPhone 5s launches True Tone flash, which can dynamically adjust the color and intensity of light, with more than 1,000 combinations. The camera of iPhone 5s is an 8-megapixel back-illuminated camera with large pixels of 1.5 microns and an aperture increased to 2.2. When the light is insufficient, iPhone 5s can automatically turn on the new image stabilization function to combine four photos taken instantly into one. The new True Tone flash is divided into white and yellow, and can adjust the imaging quality by flashing in different proportions based on the color temperature automatically measured by the iPhone 5s. It supports 10 frames per second continuous shooting and 120 frames per second 720P slow-motion video shooting. With the help of the image signal processor built into the A7 processor, the iPhone 5s' autofocus speed is twice as fast.
