How does Type-C differ from conventional USB connectors?
The USB connector appeared in 1994.
It was invented in order to unify the “socket” through which additional equipment is connected to the computer. An important feature of the USB cable is that it can transfer both data and energy (that is, charge the phone).
The USB connector is the “socket” into which the cable is inserted.
USB specification (standard) is the technical characteristics of the cable that determine its capabilities: data transfer speed, energy, and so on. There are, for example, standard 2.0, 3.0, 3.1 and others.
There are several USB connector options - A, B and C. Type A connector, for example, is used to connect flash drives and smartphones to a computer, and type B connector in mini and micro format is used in gadgets.
Variation C (Type-C) was invented in 2014. The usual micro USB connector (type B) is flat on top, rounded on the bottom, and Type-C is symmetrical - oval, so the cable can be inserted into the gadget on either side.

The new connector was required to ensure the operation of the USB 3.1 standard - it has 24 pins, while USB 2.0 has only 4. Due to the greater power, USB Type-C with 3.1 certification has become more versatile and has several interesting features.
Lightning connector
Lightning (8-pin connector) is a computer connector used since 2012 in Apple portable devices: phones, tablets and media players.
It became a more compact replacement for the previously used 30-pin connector, and later for the headphone jack. Currently, the connector is used in iPhone 8/Plus/X, iPhone 7/Plus, iPhone SE, iPhone 6S/Plus, iPhone 6/Plus, iPhone 5S, iPhone 5C, iPhone 5; iPod Touch 5th generation, iPod Touch 6th generation, iPod nano 7th generation; as well as in iPad 4th generation, iPad Air (iPad 5th generation), iPad Air 2, iPad mini/retina, iPad mini 3, iPad mini 4, and iPad Pro.
This connector only carries digital signals, whereas the previous connector also carried some analog signals. Unlike the 30-pin connector, it can be inserted into the device on both sides.

What are the advantages of USB Type-C for the user?
Plug convenience
A double-sided cable, which connects to the smartphone from either side, is much more convenient for the user - you don’t need to think about how to plug it in.
Fast charging
The USB 3.1 specification allows you to transfer a charge with a power of 100 W (USB Power Delivery technology). If a smartphone with the usual micro USB took 3-4 hours to charge, then with Type-C it can charge in an hour.

Fast data transfer
The new USB 3.1 standard supports data transfer rates up to 10 Gbps. Large amounts of data from a smartphone can be transferred very quickly, and if you connect a monitor to the gadget, it will “stream” 4K high-definition video.
Smartphones could previously be used as personal computers by connecting various additional equipment to them. USB Type-C 3.1 increases the potential of this option due to more power.

Design
The device is offered in three colors – red, blue and black. Our review shows the black model.
As for the design, the A12 looks stylish, it’s clear that the designers did a good job here. The body is made of plastic, the surface is divided into two zones with different textures. The lower part is matte, the upper part, a little more than half, is ribbed.
The smartphone looks quite fresh. However, the plastic is not of very high quality and will probably be scratched, it is better to use it in a case.
There is a camera block on the rear panel. There are 4 modules in total.
On the right side there is a volume rocker and a power button. The power button has a built-in fingerprint scanner, which works perfectly and responds instantly. The button is located conveniently under your finger.

On the left side there is a slot for memory cards. Triple slot – for two SIM cards and a memory card.

At the bottom there are a USB-C port, a microphone, and a 3.5 mm audio jack.
The screen has a resolution of 19.5:9, the front camera is located in a drop-shaped cutout. It should be noted that the previous smartphone in this line – Samsung Galaxy A11 – had a front camera in a round cutout in the upper left corner. In A12, the designers returned to the drop again, but there’s nothing wrong with that.
What are the disadvantages of smartphones with USB Type-C?
No headphone jack.
Many smartphones with USB Type-C do not have a separate headphone jack. It is assumed that the user will plug them into Type-C - now this can be done via an adapter cable, which is not very convenient. Or you will have to use a wireless headset.
Eliminating the headphone jack and switching to USB Type-C allows manufacturers to make smartphones slimmer.
You will have to carry the charger with you.
USB Type-C is not very widespread yet. If you change your smartphone, but your friends and relatives haven’t yet, then you won’t be able to use their charger.
Not all Type-C connectors are equipped with USB 3.1
Some smartphone manufacturers make a USB Type-C connector on the gadget, and inside it they put the 3.0 specification, which has weaker technical characteristics, or even 2.0. Therefore, before purchasing a smartphone, make sure that it not only has a Type-C connector, but also the USB 3.1 specification.

OTG standard
Many models of smartphones and tablets can be connected to the same models of flash drives as a PC - you only need the device to support the OTG standard and a special adapter.
Using it, you can connect to your phone not only a compact flash drive, but also a computer mouse, keyboard or gamepad. The adapter is also suitable for connecting a printer - documents and pictures can be printed directly from a mobile gadget.
What could affect the spread of USB Type-C?
Many experts and industry media suggest that the new standard will soon become ubiquitous due to its obvious benefits. Now gadget lovers are wondering whether Apple will put a USB Type-C connector in the next iPhone. The company has already released a MacBook laptop with such a “socket”.
If Apple, one of the trendsetters in the market, abandons its standard Lightning connector in the iPhone, then this will be a powerful argument for all other smartphone manufacturers. By the way, the specific iPhone cable standard has not changed for about 10 years.
Cameras
The main module is 48 MP. The pictures come out decent both indoors and outdoors. It should be noted that there is no night mode. Other modules are a 5 MP ultra-wide-angle with a viewing angle of 123 degrees, a 2 MP module for macro photography, a 2 MP depth sensor that allows you to blur the background, for example, when shooting portraits.
The front camera has a resolution of 8 MP. It produces high-quality images both during video calls and when taking selfies.
Basic video recording, 30 frames per second, Full HD resolution. There is no optical or electronic stabilization.
How have mobile phone chargers evolved?
In the 1990s, when the first mobile phones appeared in Russia, a charger of a unique format was sold with each model. Consumers endured the inconvenience of having to carry the charger with them. If it broke, it was not easy to find a replacement.
In the 2000s, multifunctional USB connectors - mini and micro - began to be used to charge smartphones. Over time, it became clear that the latter is more convenient. In 2009, the largest smartphone manufacturers agreed for the first time to produce a standard micro USB interface. In addition to comfort for users, this also solved an environmental problem - chargers of different formats were more often thrown away.
Only Apple remained aloof from the standardization process. The company still produces smartphones with a Lightning connector.
Recently, smartphones have appeared that support so-called wireless charging - when the gadget is placed on a special panel that transmits energy through the body. But so far it is supported by a few devices, mainly flagships.
Non-original chargers
Charger with higher amperage. If the current exceeds that consumed by your gadget, nothing bad should happen. The fact is that the lithium-ion battery is equipped with a special protective board that prevents overcharge/overdischarge, and sometimes even short circuit. Moreover, modern smartphones are equipped with power controllers that do not allow them to accept more current than the battery needs.

Despite this protection, it is not advisable to charge the gadget from a power supply with a higher current rating (A), since experience and forums indicate that the phone gets very hot and the battery fails faster.
Charger with lower amperage. Experts do not recommend using weaker charging. In this case, the battery will require more energy, which the charger cannot provide. This can lead to overheating of both the unit and the gadget, and sometimes even to a short circuit and fire.

Charging from another manufacturer. Many users complain that when using a Chinese charger with the same amperage and voltage, the process takes longer than the original charger.
Charger for iPhone 5/5S 1.0A
The problem is that different mobile manufacturers do not have a generally accepted standard for coding the load capacity of the power supply. Because of this, a gadget of one brand does not always “understand” a charger manufactured at the factory of another company. In this case, the charging process is carried out in a safe mode of 500 mA (0.5A) and much slower, which can also lead to overheating. There are situations when the device does not recognize the cable connected to it as charging at all.
Conclusion. We recommend using a native charger or an officially compatible one from a reputable manufacturer. Of course, in unforeseen situations you can make an exception, but you should not do this regularly. Also study and take note of the rules for charging smartphones.

Battery autonomy
At least the Samsung Galaxy A12 is ahead of all competitors in terms of battery life, thanks to a capacious 5000 mAh battery. Since it has a low-power processor, the battery can last a very long time.
In the battery test, the smartphone lasted 14 hours 38 minutes - which means you can get 2 days of work on just one charge. This is an exceptional result; among its competitors, only the Moto G9 Power is better, but the battery capacity is 1000 mAh larger.
Charging time for the Galaxy A12 is as expected - it will take you 2 hours to charge the battery from 15 to 100%.
Design and appearance
Even though the characteristics make it clear that the Samsung Galaxy A12 is not a flagship, the design does not give it away.
There are practically no bezels around the 6.5-inch screen, although the “chin” at the bottom is noticeable. The front camera is placed in a tiny teardrop-shaped cutout at the top. It's a little eye-catching, but the same can be said about any other solution.
The back cover is made of plastic; externally, the material is practically indistinguishable from metal. The lower part has a smooth matte surface, but the rest of the area is covered with protruding diagonal lines. They make the body of the Galaxy A12 slightly corrugated and contribute to a comfortable grip.
The module with the main cameras protrudes slightly above the surface, so the device lies unevenly on a flat table. The fingerprint scanner is built into the power button on the right side, which is convenient. It's worth noting that the A12 has a number of useful features that premium smartphones often lack. The device supports a microSD memory card and has a 3.5 mm headphone jack.
Overall the design is nice and comfortable. Of course, there is no wireless charging or water protection according to the IP rating, but this is not something you should count on in the budget price segment.
Battery
The battery in the Samsung Galaxy A12 is powerful, its capacity is 5000 mAh, which is excellent for a budget device. One charge lasts for 20 hours in video viewing mode.
With normal use, the smartphone will last up to two days.
The package includes fast charging, its power is 18 W. You can fully charge your smartphone in 2 hours.
Today you can find a huge variety of USB cables on sale. Their prices can sometimes differ by an order of magnitude. How to understand all this variety and choose the right Samsung charging cable? Today we will try to answer this question in our article. Of course, in this text we give tips on choosing the right Samsung charging cable. But these tips will also be relevant for equipment from other manufacturers.
Hardware performance
If the mention of the MediaTek processor initially made you wary, then your intuition did not let you down. Yes, MediaTek chipsets have become much better recently - the G95 in Realme 7 and Dimensity 800U in Redmi Note 9T show very high performance. But this can hardly be said about the Helio P35 inside the Samsung Galaxy A12.
From the first minutes of operation, the smartphone seems slow. Animations are slow and applications take a few seconds to launch. Over time you get used to it, however, the A12 is not very suitable for work and multitasking, even with 4 GB of RAM. Performance tests also confirm this.
The Galaxy A12 is far behind all its competitors in Geekbench 5, where it scores 170 and 990 in single-core and multi-core modes. Realme 7 on MediaTek G95 received 510 and 1640 points here. Other competitors are also noticeably ahead, including the Moto G9 Power or Nokia 5.3.
Graphics capabilities were tested using the GFXBench test. The A12 has only 19 fps in the native resolution of 720p, when in 1080p there are even 12 fps. Realme 7 and Poco X3 NFC showed about 4 times more results. We can safely say that even for its price segment, the performance of the Galaxy A12 is weak.
Display and display
As a display, the Samsung Galaxy A12 received a 6.5-inch PLS panel (similar to IPS from Samsung). Its resolution is 1600x720, which is approximately 264 pixels per inch.
And although this is far from the Full HD resolution that can be found on many other smartphones, the detail here is completely fine, even with such a large screen. The sRGB color space coverage is 88%, the shades are not very accurate. While the maximum brightness of 420 nits isn't impressive, the 1740:1 contrast ratio makes it all look pretty sharp.
The Galaxy A12's display isn't the worst - it's about the same as the Moto G9 Power and Nokia 5.3. But, this screen clearly falls short of the specified Poco X3 NFC standard.
Does cable length affect charging speed?
Yes, but in very different ways. For example, by extending the wire to three meters without increasing the cross-section of the conductors inside, we can lose two-thirds of the energy. A good branded cord produced according to the AWG standard practically does not lose up to two meters. We recommend buying them.
If you learn about new versions of phones from advertising on TV, then you've probably seen a lot of models from Samsung. Of course, the Korean company also has budget devices. One of these is the new Samsung Galaxy A12 smartphone that came to me for testing.
The Galaxy A12 has a large 6.5-inch display, a quad-camera system on the back, and looks like a premium model. Why is it being sold for only 12 thousand rubles? This is what I tried to find out.
Software
In terms of software, the Samsung Galaxy A12 gets a stripped-down version of the overlay called One UI Core 2.5 - on top of Android 10.
One UI Core looks and feels like the full One UI on flagships, but it lacks many of the features like Edge Panel or Samsung Pay, although this smartphone does have NFC.
In general, this is a system already familiar to many, although the stripped-down version also has a number of disadvantages. For example, you will be constantly advised to install recommended applications or games. This irritates me a little.
