Myths about iPhone📱

Today we will reveal the topic of the most popular misconceptions😉

[Like ❤️ from you, and even more useful information from us]

Myth 1. iPhone, iPad or MacBook batteries need “training” - several full charge-discharge cycles to increase capacity.

▪️No, they use batteries based on Li-ion technology, which do not require such calibration.

Myth 2. Prolonged charging reduces battery life - for example, leaving the device plugged in overnight.

▫️There is nothing to worry about, a special controller will cut off the power supply when the battery is fully charged - at least if you use a quality adapter.

Myth 3. You need to connect charging as rarely as possible - then there will be fewer of the same cycles.

▪️One cycle is a battery charge from 0 to 100%. And charging the device from 50 to 100% twice is not two cycles, but one. However, frequent plugging and unplugging the device from power still harms its battery.

Myth 4. iPad power supplies harm the iPhone.

▫️ iPad power supplies do not harm the iPhone. We will not delve into the details, but the experts with whom we talked in the framework of this material gave the green light to this. Moreover, they clarified that more powerful power supplies from the MacBook Pro do not harm the same MacBook Air - the main thing is that they be of the highest quality possible. It is better not to save on this.

Myth 5. Wireless interfaces drain the battery very much.

◾️As it turned out, they are even too undemanding to energy resources - the most voracious element of the device is its screen.

Myth 6. There are high-capacity batteries.

▫️Some repair shops or online stores offer high-capacity iPhone batteries - there were especially many of them for the fourth and fifth series. This is a divorce of pure water, because nothing like this simply can not be.

What is a smartphone display made of❓

🔵 Matrix

It consists of two plates, between which liquid crystals are located. Under the action of current, these crystals begin to transmit the corresponding illumination radiation.

This is how the IPS-matrix is used, which is used in all iPhone models except for the new iPhone X. The system itself was slightly modified by Apple specialists, and later called Retina marketers.

🔵 Backlight

A light source that is located behind the matrix. He is responsible for the illumination of the crystals so that the image becomes bright and clear. By themselves, the crystals do not glow, but only pass the light of illumination through themselves.

🔵 Layer of additional sensors

This layer has appeared in the iPhone since the iPhone 6s and is needed to recognize the force of pressure on the display.

A special grid of capacitor boards is connected to the power supply. Its task is an ultra-precise measurement of the distance from the finger to the matrix. Software algorithms analyze information from this grid and allow 3D-Touch technologies to work.

🔵 Frame

This is a kind of basis on which all the above elements are attached. The frame itself is installed directly on the frame of the smartphone.

❗️ Here is such a “sandwich” fit the developers in the display unit, the thickness of which does not exceed a couple of millimeters. The smartphone screen is not only an integral element of the design of a mobile device, but also one of its most important components.

What is a smartphone display made of❓

Part 1. ✅

The main part of any modern smartphone is its display.
Manufacturers pay almost the greatest attention to this module, because the perception of the device by the user depends on the quality of the picture and the responsiveness of the sensor.

To better understand how technologically advanced and complex the module is on the front of our smartphones, let's see what it consists of using the iPhone as an example.

🔵 Protective glass

The topmost layer of the display that the user interacts with. The tactile sensations of the user depend on the quality of the glass and the oleophobic coating on it. When working with the iPhone, the finger simply glides over the surface, does not stick with a quick press, and does not rest against a sharp swipe.

🔵 Layer of transparent glue

The protective glass is glued directly to the matrix. This allows you to remove the air gap and reduce the thickness of the display.

A high-quality adhesive layer will not distort colors, prevent dust from getting under the glass and securely hold the top layer even during the most active use.

When replacing glass, a low-quality adhesive layer can be used, which will change its color over time, begin to distort the picture or let dust particles through.

🔵 Touchpad

It is also called a touchscreen or simply a sensor. Responsible for recognizing user clicks.

The original element is made of a thin layer of glass and allows you to determine the place of pressing with an accuracy of up to a millimeter. At the same time, the sensor has support for multi-touch technology. This element suffers when falling much less frequently than protective glass.

🔵 Polarizing filter

A special layer that makes the image of the matrix visible to the human eye. Without it, we would not be able to see anything on the screen at all.

❗In the next post, we will tell you about the rest of the dispoei components🔥
