iPhone 6s is a mobile phone product released by Apple (Apple) on September 9, 2015 (September 10, Beijing time) at the Bill Graham Civic Auditorium in San Francisco, USA.

The battery capacity of iPhone 6s is 1715mAh. Built-in lithium-ion rechargeable battery, charged via computer USB port or power adapter.

• Talk time: up to 14 hours when using 3G network.

• Standby time: up to 10 days.

• Internet usage: Up to 10 hours on 3G, 10 hours on 4G LTE, and 11 hours on wireless.

• HD video playback: up to 11 hours.

• Audio playback: up to 50 hours.

Camera

The iPhone 6s has a 12-megapixel rear camera and a 5-megapixel front lens. Configuration/2.2 aperture, the single pixel size of iPhone 6s is 1.22 microns. Apple’s official website points out that iPhone 6s and iPhone 6s Plus provide optimized local tone mapping function and optimized noise reduction function. iPhone 6s supports 4K video shooting (3840x2160 pixels), 30fps. Other new shooting functions include Live Photos, zoom playback, and flash to achieve efficient fill light with the instantaneous increase in screen brightness [10] .

Processor

The iPhone 6s has a built-in A9 processor. Apple (Apple) introduced that this third-generation 64-bit chip has a performance improvement of 70% compared to Apple’s A8. The GPU has been increased by 90% to reach the desktop level, "capable of handling game console-level graphics processing tasks, making games and other apps richer in graphics." Previously, running score data showed that the A9's single-core performance has surpassed Qualcomm Snapdragon 820. The embedded action co-processor is simultaneously upgraded to M9, which uses low power consumption to cope with the continuous work of various sensors in the mobile phone and can be activated quickly [10]. Supports "Hey Siri" voice wake-up Siri function.

Wireless Network

iPhone 6s provides a full Netcom version, supporting 23 LTE frequency bands and 4G LTE Advanced, which can achieve twice the experience of ordinary LTE networks. New MIMO technology, namely Multiple-Input Multiple-Output, uses multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, so that signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving communication quality.

iPhone 6s has a built-in Bluetooth 4.2 module and built-in NFC technology, which is mainly used for Apple Pay.

Extended information：

mAh is the unit of measurement of battery capacity. It is actually the amount of electrons in the battery that can be released for external use. total. The standard unit in physics is the familiar coulomb. The international standard unit of coulomb is the ampere-second of current multiplied by time:

1mAh=0.001A×3600s=3.6As=3.6 Coulomb

mAh is not a standard unit, but this unit can be very convenient Used for measurement and calculation. For example, a 900mAh battery can provide 300mA constant current power supply for 3 hours. If you want to get the correct information about the power usage of lithium-ion batteries, you can only use a coulomb meter. Just like the working principle of the water meter used to measure water in our homes, we need to calculate the amount of charge flowing through to obtain the power usage of the lithium-ion battery.

How to get the amount of charge flowing through it? The only way is to test the current flowing through the loop per unit time. If the measured current is constant, the charge can be simply obtained by multiplying the measured current by time. This situation generally only occurs in the laboratory. A constant current is usually used to discharge and calculate the battery capacity, and the measured capacity is relatively accurate. If the measured current changes with time, then the changing current needs to be integrated to obtain the charge. This is the case with the battery on a mobile phone, where the current changes at any time.
