Throughout digital world 2020 we learned many different aspects of digital technology that made us maintain a very good perspective on what is inside different types of technology. We also learned about how different compartments work and how they affect the technology. For our project we decided to dissect an iPhone 7 Plus and talk about the different parts that is inside of it. Some of the parts inside it we didn’t even know about so we really learned a lot about parts that we didn’t even know about. The reason we are writing about this is because we really wanted to see what makes up a product that we are customers for, so we wanted to see what we are paying for.
The main part inside the iPhone 7 Plus is the battery. It is a 2900 mAh ion battery which is the most energetic rechargeable battery available in the market right now. The lithium ion battery only loses about 5% of its charge per month as opposed to the NiMH battery that loses 20% of its charge per month. The new 2900 mAh ion battery is also 5% larger than the 2750 mAh battery used in the iPhone 6 Plus. The fact that battery is bigger and stronger, its battery life goes up to 21 hour talk time which 4 more hours than previous iPhones.
A new component that Apple added to its iPhones after the iPhone 6 series was the Barometric Vent. This replaced the headphone jack that were all in the other iPhones prior to the 7. It is on the bottom left corner of your phone, the holes that look like a speaker. Since they added waterproofing, they needed to add a barometer which allows the iPhone 7 Plus to altitude and pressure. It can even measure minor changes like going up a flight of stairs or an elevator.
Another compartment that is inside the iPhone 7 Plus is the Taptic Engine. The taptic engine provides tactile sensation in the form of vibrations to users. It senses the amount of fingerprint pressure applied to the display. Users of Apple devices feel sensations that vary based on the type of feedback provided, which allows the device to quickly convey information without the user needing to look at a screen or display. One example is that the Taptic Engine may send one vibrating alert when you get an email and another type when you get a text message.
Another compartment that is inside the iPhone 7 Plus is the 339S00199 Wifi. It Cost $9.51. This the component that allows you to connect to bluetooth. The way it is wired is that it connects to the cell atena which will allow it to get connection wherever you are. Your bluetooth device will send a signal to your phone that allows your phone to pick it up and connect to it.
Lastly another main compartment is the XMM7360 Modem. This modem is for LTE advanced smartphones. Combines power management units and leading-edge capabilities in a compact, power-efficient design to deliver performance benefits.
The modem is what connects the phone to the internet instead of using a telephone or cable television lines.
The first slide that I did on our presentation was about the background information on the iPhone 7 Plus. My research process was really simple. I went onto bloomberg.com and saw that they had history of the new iPhone 7 Plus. This specific model was announced to the public on September 7th, 2016. The cost of making the phone is around $270 and it retails for $749. I thought that it was very cool that Apple introduced the dual camera lens to the new phone.
The next slide that I did was the slide explaining the front and the rear camera. It was very interesting to learn about the new camera features that Apple introduced into the new iPhone 7 Plus. As I mentioned before, Apple introduced the new dual lens camera system. This makes it possible for the camera to achieve 2x optical zoom. This new camera makes it possible to achieve the “depth of field effect”. This is when the lens focuses onto the subject and makes the background blurry. The new camera also offers image stabilization and also shoots in 4k. The lens is protected by a Sapphire Crystal Lens cover. I put in a commercial that Apple made about the new camera that I found was very interesting. It showed how crisp and clear the new camera shoots.
The next component of the iPhone 7 Plus that I wrote about in the presentation was the cell antenna. This is a very important component of the iPhone because this is what allows the phone to send and receive cellular waves, WiFi and bluetooth signals. It is located on the top of the phone. Following that slide, I did the slide on the loudspeaker. I learned that Apple introduced the stereo sound speaker by adding a speaker on the bottom on the phone and on the earpiece. So, this means that audio comes out on both speakers. These speakers have better performance than previous models.
The slide that I did after was about the Retina display and the LED screen that Apple incorporated into the iPhone 7 Plus. The screen is 5.5 inch in length and uses IPS technology. This technology gives a very crisp and clear display by providing better color accuracy. This is more expensive to produce but, it is worth the money. This phone has a 1920-by-1080-pixel resolution at a 401 pixel density. I also played a video that explained the difference of Retina and a regular display. I found the video very interesting and helpful. https://www.youtube.com/watch?v=kcnKi7GxZ2k
The last slide that I did was about the flash memory. The standard iPhone 7 Plus comes with 32GB memory but other models feature higher capacity. Flash memory consists of two transistors. One of the is called the floating transistor and the other is the control gate.
