After the first year of testing iPhone 8 and 8 plus, we can already draw conclusions about the pros and cons of the model. The impression is positive; under the not-so-new body is hidden a powerful machine that has shown itself positively in different operating conditions.
Before drawing conclusions, let’s remember the characteristics of the iPhone 8 and 8 plus:
- iPhone 8 size – 138.4x67.3x7.3 mm, weight – 148 g; iPhone 8 plus – 158.4x78.1x7.5 mm, weight – 202 g.
- Widescreen LCD display, Retina HD, Multi‑Touch function with IPS technology. In iPhone 8, the resolution is 1337x750 pixels, the contrast is 1400:1. In iPhone 8 plus – 1920x1080 pixels, 1300:1. Supports True Tone auto white balance function.
- IP67 dust and waterproof rating.
- A11 Bionic with neural brain.
- Camera 12 megapixels. 10x digital zoom. Record 1080p HD video at 30 or 60 fps.

Apple continues to work on optimizing smartphones for people with disabilities and health problems. iPhone 8 and 8 Plus feature accessibility features. Thanks to special options, a person with visual or hearing impairments can customize the controls to suit themselves: use a magnifying glass, dictation, subtitles, and read the screen out loud.
Equipment
A description of the iPhone 8 and 8 plus would not be complete without a list of accessories for the smartphone. Unfortunately, the tradition of a small box with minimal filling was followed this time too. The gadget comes with:
- standard charger with Lightning cable;
- headphones with Lightning connector;
- adapter from Lightning to standard 3.5 mm;
- a paperclip for prying up a SIM card;
- screen film;
- instructions.
Until the last minute, fans of Apple gadgets hoped that a wireless charging device would be included in the package. But the company never released its own docking stations, so those who want to take advantage of the cool new feature will have to look for charging outside. Engineers equipped smartphones with Qi technology; any device with the same expansion is suitable for charging.
How can you restore capacity?
It is almost impossible to restore the capacity of a lithium-ion battery. Methods for improving this indicator of electric current found on the Internet have not been confirmed in practice.
If the capacity has dropped sharply, then the only effective method of restoring the device’s functionality is to purchase and install a new battery.
Constantly plugging the charger into the network to supply the smartphone with electric current is a harmful operating mode for the mobile device, which also leads to excessive consumption of electricity and can be dangerous if the wires are short-circuited.
Still have questions or have something to add? Then write to us about it in the comments, this will make the material more useful, complete and accurate.
Weight and size
The iPhone 8 and 8+ have undergone subtle changes in size and weight, but for a complete analysis even such little things are important:
- The weight of iPhone 8 is 148 g, which is 10 g more than the previous model, 8+ is “fat” by 8 g.
- The length of the iPhone 8 has increased by 1 mm, the thickness by 2 mm.
Changes in weight and dimensions occurred due to the appearance of the wireless charging function, as well as due to a change in the material of the rear panel. Instead of aluminum, the lid is now made of tempered glass.
Design
The shape of the iPhone 8 smartphone is identical to the lines of the iPhone 7, but this is only theoretically; in practice, two identical designs are radically different from each other. Thus, the iPhone 8 is equipped with a glass back panel, which made it possible to modernize the exterior without any additional effort or financial investment.
The front panel is also made of glass, which is ½ stronger than anything previously used by the company. The glass is complemented by a frame made from aerospace-grade aluminum, which is painted the same color as the iPhone body.
The smartphone fits easily and comfortably in your hand, without slipping in it at all, and you don’t even need to squeeze it, because by some unimaginable miracle, the device lies in it without any problems. If you remember that the panels are made of glass, then this fact is really surprising.
On the front part at the bottom of the case there is a Home key, taking its “rightful” place (remember, only the iPhone X model was released on the market without it), and on top there is a front-facing camera along with a built-in microphone and stereo speaker. The bottom edge is complemented by another built-in microphone, speaker and Lightning connector.
On the right side there is a cell for storing a SIM card and a power button, on the left there is a key for adjusting the volume. That is, all the parts are in the same places as on the iPhone 7.
The smartphone case is protected according to IP67 standards from the penetration of water and dust, but in this regard, the developers cannot imagine any improvement.
The phone is released in gray, silver and gold colors.
On the front surface, the slightest fingerprints remain clearly visible, although the gray tint, to the best of its modest capabilities, tries to hide them. On models in other colors this flaw is noticeable several times more, so if your phone has a different color, fingerprints will be a real disaster.
Updated design?
Every year, lovers of Apple gadgets expect something revolutionary, and every year they are disappointed. Yes, there are few external changes in iPhone 8 and 8 plus:
- The back cover is now made of tempered glass.
- The company logo on the reverse side has shifted slightly.
- Three body colors are available: “Gold”, “Silver”, “Space Grey”. A limited edition red series of smartphones was released.
If Apple did not make major changes to the appearance of the next model, then this was necessary to achieve a different goal than a pair of “Wow!” from users. The design of iPhone 8 is a legacy of the style of the last ten years of the company's work; the model became a transition point between the old and new generations of smartphones. The role of the flagship was given to the iPhone X, and the “eight” was a pleasant surprise for fans of the usual design. The iPhone 7 case embodies the latest achievements of engineering.
iPhone 8: advantages over iPhone 7 Plus
iPhone 8 - a modern device
If you have an older iPhone model - the fifth or sixth, then it is worth changing it to the “eight”. But, if you already have a “seven” in your hands, then the difference is almost imperceptible. Let's figure out what are the advantages of the iPhone 8 over the iPhone 7 Plus? It is better to see this in the table:
iPhone 8 and iPhone 7 - comparative characteristics
The benefits are many and noticeable. But, when you hold the “eight” in your hands, which you purchased as a replacement for the iPhone 7, then, as mentioned above, the distinctive features will be scanty.
Waterproof
Like the “seven,” the iPhone 8 received an IP67 rating according to a standard that determines the smartphone’s resistance to solid objects and water. The model is protected to the maximum from dust, as indicated by the number 6. But with water resistance, everything is not so simple. A value of 7 means the following:
- the device can be in water for 30 minutes without damaging the electronics;
- immersion depth 1.5 m.
As a result, iPhone 8 cannot be called waterproof; only devices with ratings of 8 and 9 are called that. The Apple smartphone is rather water-resistant and can withstand short-term exposure to water and moisture. Moreover, liquids with a different consistency are doubly destructive. If sweet coffee, tea or soda gets in contact, you must immediately clean the surface.
↑ Other features
All 2022 Apple smartphones are protected from moisture and dust according to the IP67 standard.
iPhone and iPhone 8 Plus can be submerged in water to a depth of 1 meter and remain there for 30 minutes. They are equipped with a physical Home button with a built-in fingerprint scanner. Both gadgets are equipped with Wi-Fi 802.11ac, Bluetooth 5.0, NFC for Apple Pay contactless payments, as well as GPS and GLONASS for navigation. The LTE module built into the processor provides download/upload speeds according to the Cat.12 standard (up to 450 Mbit/s).
Also, do not forget about the presence of support for ARKit, which ensures the operation of augmented reality technology. It uses Metal 2 and Core ML software to improve system resource efficiency.
Memory
iPhone 8 received 2 GB of RAM, 8+ respectively 3 GB. The memory of the iPhone 8 has not changed in digital terms compared to the previous model, but the performance and other functions of the smartphone have improved. Causes:
- A processor with a neural brain that analyzes, learns, and searches for optimal options for using data.
- 6 cores distribute and simultaneously solve many tasks.
- iOS 12 has become faster to process and respond to requests.
Traditionally, the capacity of the iPhone 8 and 8 plus is 65 GB or 256 GB, depending on the configuration and price. Practice has shown that 2 GB of RAM and 65 GB of memory are enough to load “heavy” games and complex programs with the augmented reality function.

Battery capacity
The battery in iPhones remains the most talked about part. Today, the requirements for the battery are not so stringent; if a smartphone dies only in the evening, it’s already a holiday. Therefore, the news that the iPhone 8 battery was no longer 139 mAh smaller than on the “seven” (1821 mAh versus 1960 mAh) aroused indignation.
The reason for the reduction in battery capacity of the iPhone 8 is that wireless charging and other elements have been added to the case. But you shouldn’t be upset; the manufacturers promised that the difference will be compensated by better optimization of the smartphone.
As a result, in the very first months of testing, the iPhone received positive ratings among developers and ordinary users. When compared with the “seven”, the gadgets of the eighth series performed no worse, and sometimes even better, than the previous model.
Processor, memory and battery

The iPhone X has better parameters: battery capacity, talk time and battery life when listening to music. The iPhone 8 failed to compete in this comparison.
Charging in a new way
Back in the 90s and 00s, wireless charging was only in the arsenal of superheroes and heroes of science fiction films. And today, every year, the range of smartphones that support charging through inductive energy transfer is expanding. iPhone 8 and 8 plus were the first in the Apple line to receive this technology. Advantages of wireless charging:
- quick replenishment of energy volume, 100% battery in 30-40 minutes;
- no wires;
- charging from a distance.
iPhones 8 and 8 plus are currently only equipped with a regular charger. The company will begin its own production of docking stations in September – October 2022. For now, the user is offered to purchase devices from other manufacturers. Fortunately, iPhones support the Qi transmission protocol, on the basis of which all such devices operate.
Fast and wireless charging
This is one of the first gadgets from the brand to receive fast charging functionality. Thus, the iPhone 8 charges up to 50% in half an hour, provided that a fast power adapter with a power of up to 87W is used.
Wireless charging can also be used, but since the package does not include a docking station, it will also need to be purchased separately, fortunately, the gadget supports any Qi series device. But remember that the smartphone gets very hot when powered wirelessly, so you should use this charging method only in extreme cases.
New generation of processors
Today, A11 Bionic is the most powerful and intelligent processor for smartphones. Some cores work for performance, some for energy efficiency. What does it give:
- In multitasking mode, the gadget works 3-4 times faster than previous models.
- Optimizing games and augmented reality applications.
- Even with intensive use, energy consumption is minimal.
The main feature of the A11 Bionic is the learning ability of the processor. It does not easily pass a signal through itself, but remembers it, correlates it with others and develops a work strategy. If this continues, the emergence of artificial intelligence will only be a matter of time.
WiFi
Wireless LAN technology today is present in almost any device that contains microcircuits. It is possible to develop here only in the direction of increasing speed and expanding areas of use.
Wi-Fi iPhone 8 is represented by the 802.11ac standard with MIMO technology, which increases signal throughput. In iPhone 8 and 8 plus, Wi-Fi performs the following functions:
- for data transmission;
- to connect to the Internet;
- to determine geoposition;
- for video communication.

The iPhone 14 series will receive a new 5G modem
The fifth beta version of iOS 15.4 and iPadOS 15.4 has been released
In previous Apple models, frequent complaints from owners are related to Wi-Fi not working: it is impossible to connect to the network, the password is not accepted, the Internet is slow. The problem is solved by updating to the latest software version. Back in iOS 11, the vulnerability problems of the Wi-Fi chip on iPhones were solved, and in iOS 12 even more so.
Is it possible to increase the capacity of the phone
If your iPhone's battery charge drops quickly, then most likely the phone's battery is no longer able to store enough electricity. This problem can only be solved by installing a new original battery.
If for one reason or another it is not possible to do this, then you should preserve the supply of electric current by turning off unnecessary programs and functions. You can cope with increased current consumption by lowering the screen brightness, turning off Wi-Fi and wireless data transfer (when this is not necessary).
Purchasing high-capacity Chinese batteries for installation in a mobile device of this type is also not recommended. Such products are not certified, so they can not only quickly fail, but also cause significant material damage in the event of spontaneous combustion.
Headphone jack
Everyone has become somewhat accustomed to the fact that iPhones now offer headphones exclusively with a Lightning connector. Although at first this decision by Apple irritated users. Despite the universal hype, the reasons for changes in the format of listening to music are serious.
If with a 3.5 mm jack the sound quality depended on the device and listening means, now the functions of a digital-to-analog converter are embedded in the headphones themselves. Accessory manufacturers have the opportunity to create a product with their own settings. True, the cost of a worthy product will be appropriate.
Professional camera in your pocket
The camera capabilities of the iPhone are one of the reasons for the popularity of the smartphone. And here the G8 did not disappoint and worthily continued the tradition of stunning pictures of Apple models.
Advantages of the camera in iPhone 8 and 8 plus:
- larger matrix;
- optical stabilization during photo and video shooting;
- many image processing functions, including advanced portrait effects;
- convenient scaling control;
- video recording in 4K format, possible frame rates of 24, 30 and 60 frames per second;
- 2x optical and 6x digital zoom;
- the ability to record slow-motion videos at 120 and 240 frames per second.
Thanks to a more powerful processor, image processing takes 70% less time than on the “seven”. Apple placed special emphasis on portrait photos. The mode now supports several cool effects, the list of which continues to grow.
Camera options
Do you often take photographs? Let's determine whether there are differences in cameras. Table below.
| iPhone X | iPhone 8 | |
| Main camera | ||
| Description | Dual camera system 12 MP: wide-angle and telephoto | One 12 MP wide-angle camera |
| Matrix resolution | 12 MP | 12 MP |
| Digital zoom | 10x | 5x |
| Optical zoom to increase | 2x | — |
| Front-camera | ||
| Matrix resolution | 7 MP | 7 MP |
Digital zoom allows you to shoot objects at a considerable distance; in this regard, the iPhone X is superior to the iPhone 8. Also pay attention to the optical zoom option.
Display
The main characteristics that Apple has equipped with the iPhone 8 and 8 plus display are similar to those of the previous model: a wide-format LCD display with support for Multi‑Touch and IPS technology, which provides a maximum viewing angle and excellent color reproduction.
The iPhone 8 screen has a size of 4.7 inches and a resolution of 1337x750, the model 8+ has a corresponding 5.5 inches and a resolution of 1920x1080 pixels. Everything is the same as the “seven” except for the support of new technology – True Tone. This program, using sensors, constantly measures the level of lighting indoors and outdoors, and based on this data it adjusts the white balance on the screen.
What are the advantages of the program:
- regardless of the time of year and location, the image on the screen is presented as printed on paper;
- when viewing, eye strain is reduced;
- changes in color ratio occur instantly, almost imperceptibly to the human eye.
True Tone adjusts even to bright lighting, so you'll no longer have to squint trying to see lines on the screen outside at midday.

Checklist for choosing a reliable service center for repairing Apple equipment
Prices
Fair, not overpriced and not underestimated. There should be prices on the Service website. Necessarily! without asterisks, clear and detailed, where technically possible - as accurate and conclusive as possible.
Deadlines
If spare parts are available, up to 85% of complex repairs can be completed in 1-2 days. Modular repairs require much less time. The website shows the approximate duration of any repair.
Warranty and responsibility
A guarantee must be given for any repairs. Everything is described on the website and in the documents. The guarantee is self-confidence and respect for you. A 3-6 month warranty is good and sufficient. It is needed to check quality and hidden defects that cannot be detected immediately. You see honest and realistic terms (not 3 years), you can be sure that they will help you.
Stock
Half the success in Apple repair is the quality and reliability of spare parts, so a good service works with suppliers directly, there are always several reliable channels and your own warehouse with proven spare parts for current models, so you don’t have to waste extra time.
Free diagnostics
This is very important and has already become a rule of good manners for the service center. Diagnostics is the most difficult and important part of the repair, but you don't have to pay a penny for it, even if you don't repair the device based on its results.
Service repairs and delivery
A good service values your time, so it offers free delivery. And for the same reason, repairs are carried out only in the workshop of a service center: they can be done correctly and according to technology only in a prepared place.
Convenient schedule
If the Service works for you, and not for itself, then it is always open! absolutely. The schedule should be convenient to fit in before and after work. Good service works on weekends and holidays. We are waiting for you and working on your devices every day: 9:00 - 21:00
The reputation of professionals consists of several points
Company age and experience
Reliable and experienced service has been known for a long time. If a company has been on the market for many years and has managed to establish itself as an expert, people turn to it, write about it, and recommend it. We know what we are talking about, since 98% of incoming devices in the service center are restored. Other service centers trust us and refer complex cases to us.
How many masters in areas
If there are always several engineers waiting for you for each type of equipment, you can be sure: 1. there will be no queue (or it will be minimal) - your device will be taken care of right away. 2. you give your Macbook for repair to an expert in the field of Mac repairs. He knows all the secrets of these devices
Technical literacy
If you ask a question, a specialist should answer it as accurately as possible. So that you can imagine what exactly you need. They will try to solve the problem. In most cases, from the description you can understand what happened and how to fix the problem.
Openness of the service is the key to mutual trust and cooperation
Social media
If they are trying to organize a convenient service for you, you will definitely find the company on VK, Facebook, Instagram, and of course, on the Youtube channel. Here you can always, in an informal setting, look at the life of the service from the inside, evaluate examples of repairs, and communicate with specialists live. It’s convenient, and now you simply can’t live without social networks
Faces of the company
Apple's seasoned experts and engineers are superheroes, but they don't wear masks. On the website and on social networks you can always see who you are going to, see photos and learn a little about the engineers and service managers. You can write to each of them, suggest or clarify something with someone with whom you have already communicated.
Reviews
You can understand a lot from reviews if you treat them correctly. The overall assessment of the service should be positive and high. But the rating cannot be maximum. Reviews can be both positive and negative, the main thing is that they respond to them, communicate, make decisions, help, that is, treat them like a human being.

Firmware
Apple operating systems are improving every year. Each subsequent OS took into account the errors of the previous one, so the evolution of modern technologies can be traced based on the characteristics of iPhone software.
A year ago, the iPhone 8 iOS 11 firmware was considered an achievement of the company's developers. In June 2022, the beta version of iOS 12 was launched and received positive reviews almost immediately. What has changed in the software:
- tactile sensations from using the sensor have improved;
- data processing speed has increased;
- Working with multiple tabs has become easier and faster.
The problems of iOS 11 were fixed: freezing of augmented reality applications, “heavy” games, bugs when opening Internet pages. Famous bloggers and IT experts spoke in favor of updating the firmware.
Face ID
One of the main features of the iPhone is its specific way of personalization. If in smartphones from other companies data protection is represented by standard security settings options: a code, a special picture or word, then in the iPhone it’s a show.
Face ID or face scanner was developed and introduced by Apple in 2017. The technology has replaced the Touch ID sensor or fingerprint identification. Information about the mathematical image of a face will be stored on the processor and will be inaccessible to ill-wishers.
Unfortunately, the iPhone 8 did not receive Face ID, since the program was developed for the new generation of smartphones. The first model with facial recognition was the iPhone X.
Settings
After purchasing a new smartphone, the question arises about its activation. A common problem is transferring information, files and music from a previous device.
Instructions on how to set up iPhone 8:
- After turning on, a greeting will appear on the screen, move the word “Hello” to the right.
- Select the appropriate one from the list of languages.
- Turn on your Wi-Fi or cellular network and geolocation feature.
- Set your fingerprint on the Touch ID screen.
- Create an access code.
- Select the “Applications and Data” option and transfer your old data.
- Next, identify yourself using a password.
- Set up Siri technology.
The last stage of setup is transferring data from a previous Apple or Android device. Make sure the files are downloaded to the new device.
How to find out the actual capacity
It is almost impossible to view the actual battery capacity using programs installed on a smartphone. For this purpose, you will need to take a measurement using a multimeter.
You can also find out about the battery status of any iPhone through the phone settings
The work is performed in the following sequence:
- Fully charge your smartphone battery.
- Remove the battery from the iPhone case.
- Select a fixed power load.
- Connect the electricity consumer to the battery through a multimeter set to current measurement mode.
- Record the values of the measuring device and turn on the timer.
- When the operating intensity of the electrical device is reduced, the actual operating time of the load on the smartphone battery is recorded.
To obtain the capacitance value, it will be enough to divide the time by the current in the circuit. This way you can find out the number of ampere hours
When selecting a load for this type of diagnosis, you should not exceed the maximum current value. You can find out this parameter on the battery case or in the instructions for the gadget.
Note! You can also find out the capacity of your smartphone using the AccuBattery and the iBackupBot . How to use them is described in detail HERE .
Price
The cost of the treasured smartphone depends on the presence or absence of the “plus” prefix, the color of the case and the amount of built-in memory. The cost of Athos 8 plus with 256 GB will be 69-71 thousand rubles, whereas a year ago sales started at 80 thousand rubles. The price dropped by 30% in 9-10 months.
It is worth giving credit to Apple, who know how to sell products better than anyone in the world. The cost of iPhone 8 at 40-60 thousand rubles could seem to be an obstacle to mass sales, because in Russia this amount for the majority is equal to two months’ salary. Fortunately, loans and installment plans have already been invented.
It’s difficult to categorically answer the question whether the iPhone 8 and 8 Plus are worth the expense. Rumors about the quality and superiority of the gadget over others are justified. But when buying, you need to correctly assess your strengths and not allow a digital gadget to become a cause of financial difficulties.
