If your battery isn't charging as well as it should, don't immediately assume that your charger has gone bad or your battery has gone bad. Based on personal experience, the problem in this case (and the solution) may be much simpler than you think. If your phone or tablet isn't charging properly or isn't charging at all, we'll show you 10 ways to fix a phone that's having charging problems.

Why is my phone not charging?

This problem may occur due to various reasons. Either your phone doesn't charge at all when it's connected to the charger, or it charges very slowly (sometimes a little faster than the discharge process occurs). In principle, this is a very common drawback, and we ourselves have encountered this. Below we provide a list of possible solutions.

Repair the USB port yourself

The fastest, easiest and most successful solution would be a little soldering on your working device. The problem is that often the metal surfaces inside the USB port and microUSB charger do not allow good contact either due to a manufacturing defect or due to the charging cable being constantly connected and disconnected.

All you need to do is turn off your device, remove the battery (if possible) and use a small object, such as a toothpick, to lift up the small plate inside the USB port of your smartphone or tablet. Do this very carefully and gently. After this, you need to reinsert the battery and connect your device to the charger. In 9 out of 10 cases this method gives a positive result.

Remove lint, dust and leftover sweets

Do you carry your phone in your jeans pocket? If so, then in this case the culprit will be various piles: we have already lost count of the numerous cases where the cause is bad USB charging it turned out to be lint from your Levis.

We also saw phones whose charging ports were filled with chocolate: in such cases, the phone was placed in a bag next to a package of sweets. A can of compressed air will help blow out the foreign elements and your USB connection will be back to normal.

Replace cable

The most unreliable element of the charger is its cable, and not the adapter that plugs into the outlet. Users of Apple products are especially vulnerable in this situation, since the normal life of expensive branded Lightning cables is likely to be no more than 15 minutes. Many cables are used very harshly, and endless bending and twisting takes its toll.

Replacing the USB cable that came with your phone with any other is another aspect of a negative charging experience. The most in a simple way To determine a faulty cable, you will need to replace it with another one, followed by checking how it works with your device. If everything is in order with such a cable, then it’s time to purchase new cable, and if not, then in this case something else will be the culprit of the problems.

Diagnosing a suspicious adapter

If the cable doesn't look like it might be causing the problem, then it's worth checking the adapter that plugs into the outlet (especially one that has a charging cable that can come loose). We've encountered problems with numerous chargers where the USB port becomes a little loose due to frequent unplugging and plugging.

We also recommend that you make sure that the same adapter-cable combination works on different devices - this can help you rule out the possibility that the fault lies with your device and not with the cable or adapter. In addition, it would not hurt you to check the functionality of the outlet, that is, whether there is any malfunction in it.

Safety first

Our advice to you: do not charge your phone near water or in extremely hot or humid conditions. Also, you should not overcharge your device; charging the phone throughout the night, while it needs no more than two to three hours for this, is not best idea. This may cause the battery to explode or damage your phone.

Even though your device has a built-in charge controller for your battery, sometimes it doesn't work (you may remember stories of exploding batteries from 2013). Better to be safe than sorry. Or burn to the ground.

If you're replacing a charger or cable, be careful: the internet is littered with reports of cheap third-party chargers exploding in the middle of the night or overheating smartphones. As with any electrical equipment, make sure whatever you buy meets certain safety standards.

Replace the battery

Unfortunately, batteries do not last forever, and after a few years they find it difficult to keep a full charge. The more often you charge and discharge them, the sooner they will have to be replaced. If your battery starts to die after just 6 months, then it is probably simply faulty and you should file a warranty claim for a free exchange. new battery. But if it is already 2-3 years old, then in this case the “life” of such a battery is coming to an end.

Note that some faulty batteries are very easy to identify, as they begin to swell or leak electrolyte. If nothing like this is visible from the outside, then you need to remove back cover device and inspect the battery (if, of course, you succeed - some devices are produced with sealed battery compartments).

If the back cover of the device does not open, we recommend that you place the device with the screen facing up and rotate it around its axis. A swollen battery will deform the back cover - you may not see the swelling on the battery, but it will be enough for the device to spin. If you suspect your battery is swollen or leaking, remove it or take your phone to a repair shop. service center and buy good replacement such a battery.

Different chargers charge differently

Typically, charging from an electrical outlet is always faster than from a computer or laptop, since computer USB ports are designed to small current. The socket can supply twice as much current as a USB port, and in the case of so-called fast chargers, even 5 times more. This indicates that charging is much faster. If your phone is charging slowly, and from a laptop, this is the essence of the problem.

If your charger doesn't work very well in your opinion, try something else that suits your device. A charger from another phone will not always be able to provide the required voltage and current - for example, a charger for a Bluetooth device will be less powerful than one that is specifically designed for charging smartphones. In the case of new premium phones, it must be a phone that supports the feature fast charging, although this phone's charger is not a fast charger. We advise you to read the information on this topic printed in small print in the documents for such phones.

Upgrade or rollback

Software updates and new ones Android versions may cause some damage to the life of your battery, especially when upgrading an older device to the current software. New devices are often optimized to take advantage of the latest software, having pre-optimized hardware and software on board, while your 2-year-old device has some problems receiving updates.

If this happens to you and you cannot get rid of such problem, then you should downgrade your device to an earlier version of Android. But remember that this comes with big risks. Highly recommended to protect your device latest versions Software, although it's worth noting that the risks associated with leaving an old working version on your device are often negligible.

Likewise, sometimes your device's battery life can be significantly increased thanks to a certain update, so if you think you're behind the times with your old Android software, you should go to Settings and open About Device " to check for updates.

Turn off your mobile device

When various applications or functions intensively use the battery while it is charging, this will affect how long the battery life will decrease. If you are charging a device and at the same time communicating with someone on Skype at 100 percent display brightness, it is natural that such a device will require a longer period of time to charge than with the screen off and Wi-Fi and 4G turned off.

If you want your battery to charge as quickly as possible, switch (or turn off, respectively) Airplane mode. Imagine that your device is immersed in a kind of energetic sleep. Or fueled by a Red Bull energy drink in the dark.

Calibrate your battery

Sometimes what your device “thinks” about your battery may be different from what actually happens. The effect in this case is that your phone may perform differently based on an estimate of the remaining charge in the battery, including limiting performance before the charge level drops to as little as 2 percent.

Not long ago we already published detailed guide on the topic of how to calibrate a battery, so we will not re-post the information, we will only say that this is a very useful option that is worth trying before saying goodbye to your “dead” battery forever.

If all else fails, then you need to double check that you actually have the power saving mode turned on. This is the first thing the device manufacturer's office will ask you if you call them for assistance. By the way, this may be the next step for you if none of the methods described above helped you.

If tickling and belly rubs are your thing main reason, why you need a feline friend, then the Petit Qoboo robot may be a little strange for you, but almost an animal. The robotic companion is a fluffy therapy pillow with an expressive tail that looks like a cat substitute.

A larger model of the robotic therapy pad with a tail can already be purchased on Amazon for about $150, but the new Petit Qoboo robot model, which debuted last year at the 2020 CES electronics show, is still in the prototype stage. The creator of the new robot is working on an ambitious schedule and hopes his miniature cat replacements will hit store shelves later this year.

Video review of Petit Qoboo: Comparison of the old and new model of the companion robot.

Comment on the history of the creation of the robot "Petit Qoobo", from the developer:

Saaya Okuda, overseas marketer at Yukai Engineering Inc:

"Yukai Engineering Inc. decided to create a new companion for Qoobo, "Petit Qoobo", as a result of listening to the voices of Qoobo owners and fans. We received comments hoping for a smaller, more portable version of Qoobo that could be carried around. There were also requests for additional functions, which would make Qoobo more realistic. "Petit Qoobo" and its features are a response to these voices.

"Petit Qoobo" is much smaller than the original Qoobo, and users can easily carry it with them when going out, taking it to a friend's house, and so on. In addition to Qoobo's original feature of wagging its tail in response to touch, "Petit Qoobo" also responds to loud sounds such as clapping its hands or saying its name. Users can also feel slight heartbeat and breathing movements, which provide a more realistic quality. "

ETH Zurich has unveiled details of "Concrete Choreography", an installation that recently opened in Riom, Switzerland. The innovative installation features the first robotically constructed 3D printed concrete stage, consisting of formless columns 3D printed to full height in 2.5 hours. The process is expected to significantly improve the efficiency of concrete structures while achieving the fabrication of complex material components and construction robots.

3D printing news: ETH Zurich creates concrete columns using a special 3D concrete printer.

In Riom, Switzerland, the Origen festival features nine 2.7-meter-high columns. Each column is 3D printed concrete. The new columns were individually designed using custom software and manufactured using a concrete printer, a new automated concrete 3D printing process developed by the ETH Zurich team with support from NCCR DFAB.

MSc Digital Fabrication and Architecture students explore the unique capabilities of multi-layer extrusion printing, demonstrating the potential of computer-aided design and digital fabrication for the future of concrete construction. Perhaps the construction industry this process in the future it will become more environmentally friendly if they develop new eco-concrete for 3D printing.

Video review of 3D concrete printing: Concrete choreography.

This is how easy and fast 3D concrete printing works.

3D printing of houses and buildings made of concrete is a prospect for construction.

Hollow concrete structures are printed for the strategic use of materials, resulting in a more sustainable approach to specific architecture. Additionally, the calculated material structure and surface textures are an example of the versatility and significant aesthetic potential of 3D concrete printing when used in large-scale structures.

The new review will be about printing on a 3D printer with metal.

It is worth noting that there is technology to carry out 3D printing with metal. It's the same promising direction for construction, but for this they use other materials (for example, powder), programs and other types of printers (which we will talk about soon).

What color is your mobile phone? Is it black, red, white, gold or blue? Most likely, rear end your phone has some single-color option, which you will find in the coloring set for beginners. It has taken too long for most phone manufacturers to realize that phone colors actually matter to consumers, and it is only recently that they have started giving mobile phones not just a rarely used color, but fancy shades like coral red or canary green.

Honor News: With new 3D holographic color phones from Honor, it's possible to add a little new color to life.

It's no surprise that most people don't mind hiding the backs of their phones behind an opaque plastic case. In cases, the user can choose a suitable color for the phone case to give the mobile a little personality. But China's new Honor 20 Pro and Honor 20 series phones are the world's first smartphones with 3D dynamic holographic design, and their reflective appearance could become a new industry standard.

"Always better" is the company's motto. Perhaps this motto suggests that she refuses to follow the industry standard by simply experimenting with layers of paint with each new phone model.

Color 3D holography for the phone case.

In order for the phone body to achieve a shimmering optical illusion, the manufacturer Honor designed its Honor 20 model with a deep layer containing millions of shimmering microscopic prisms, and on top of this a so-called 3D curved glass layer is placed. The combination of these technologies causes the light to "play and dance" on the back of the phone as the user turns it in different directions.

Two colors for the Honor 20 phone can be found under these dynamic layers, Midnight Black and Sapphire Blue. Sapphire Blue). Unlike the newfangled phrases for some phone colors, Honor mobile has color gradients for phones that actually evoke the effect of a shimmering night sky or a shimmering jewel.

While the color options sound exciting, you can go even further with the Chinese Honor 20 Pro phone. This upgraded model features the signature "Triple 3D Mesh" containing three layers. Instead of just painting back panel The phone itself, this time with a body-colored layer, sits between the outer 3D layer and the inner depth layer. According to the phone maker, this makes color shifting effects much more dynamic.

The Honor 20 Pro mobile phone is actively sold in two colors such as Phantom Black and Phantom Blue. Although the names of these phone colors are not so metaphorical, do not think that their rear panels are less dynamic.

Honor's obsession with choosing the right colors may seem overly dramatic, but in the UK, for example, a survey of hundreds of Brits found that forty-nine percent of them consider color when choosing a phone to buy.

Why is a phone with a changing color scheme being sold?

What is a phone for? Choosing a mobile phone, as Honor designer Jun-Soo Kim puts it, is “Extending human life.” Essentially, Honor is saying that customer identity cannot be captured in one unchanging color.

The history of the creation of Honor color phones.

The Honor 20 demonstrates the natural evolution of the company's experiments with dynamic color in phone design (irridescent colors). The Honor 8 model started the trend of a 2.5D multi-layer back wall, which creates a 3D lattice effect. Then the Honor 9 version turned into a phone with a curved 3D glass, echoes of which can already be found in the Honor 20 model. Well, last year, the Honor 10 model was equipped with an Aurora rear glass that reflected colors from all sides.

What is the screen like on an Honor phone?

Honor's design innovations don't stop at the color of the phone's body. It is worth paying attention to the location Honor cameras 20. Instead of cropping the screen to make room for the “selfie” camera. The phone maker has cut a 4.5mm hole in the top left corner of the screen, thereby leaving more screen space for the user's needs.

Camera with artificial intelligence or AI camera in your phone.

According to the description of the phone, it is worth noting that on the back of the device, the Honor 20 AI camera has four lenses and is located so as to leave more space for a battery with more memory. But most importantly, the result is a 48-megapixel camera that uses the Kirin 980 AI microchip to take DSLR-quality photos and enhance photos.

Summary of Honor phone color.

As a result, phone descriptions, technical compatibility and cutting-edge hardware innovations are what usually attract attention to Chinese Honor phones. But in this case, the technology is almost overshadowed by the uniquely colored body design, which may make some users reluctant to go back to simple 2D phone body colors in the future.

Rumors continue to arise regarding the launch of the Google Pixel 4 mobile phone. A new set of information or predictions comes from a leaked image (3D rendering of colored cases) on the Internet, which is believed to be of the Google Pixel 4. It is not uncommon for users to spy Because of the theme of new products, such images are overlooked. Meanwhile, for some analysts, the new picture helps make a few assumptions about more than just the color of the phone.

New, unofficial, Google image Pixel 4 is sparking rumors about color options for the mobile phone's body.

While another image of the phone body itself doesn't seem to show more than what was previously discussed online, the model seen in the background of the photo raises eyebrows due to its color. That mobile phone has a shade of purple that the Pixel model didn't have before.

Elsewhere, there have been other leaks of the same Google Pixel 4 with "three phones" (variants) stacked in a row. There are white and black colors, plus the third has a bluish tint, which some call mint green. Would you like to buy a blue phone? Probably the name of the phone colors will still be updated.

Whatever leak about the phone's colors is true or false, it's safe to assume that this year's new Google Pixel 4 will definitely have additional color. What's even more interesting is that in the image, the physical buttons on the sides of the phones contrast with the color of the body. You can see white, blue and yellow buttons which give the phone a fun look.

For some strange reason, all the images and leaks seen so far have only shown the back panel Google smartphone Pixel 4. As reported in various sources, allegedly Google company shared a rendering of the phone, and there was also a part where the square camera bump appeared. The dual camera unit was visible.

The leaked photos being discussed, including the image along with the cases, show the back panel in different colors and the camera module. What do you think? better color phone?

About specifications Google Pixel 4:

Obviously, the idea of ​​a fingerprint scanner is not leaving fans alone. Some people want the phone to either have Face ID to unlock the phone, or an in-display fingerprint scanner, or both.

Some other aspects and specifications, such as the dimensions of the phones and the overall thickness being 8.2 millimeters higher compared to the 7.9 mm seen in the Google Pixel 3 and Pixel 3 XL, can be taken as close to reality.

There is speculation that the Google Pixel 4 and Pixel 4 XL versions of the phone may be more like the " Apple iPhone 11" which is scheduled to be released in a couple of months. When, more precisely? Technology company Google has not yet announced the official release date of the Pixel 4, but various sources are hinting at the release of the new phone at the end of the year.

Have you ever wondered why you need a telephone? latest model? We'll tell you more about this soon, so stay tuned for news about new smartphones from Google.

Robotics news: MIT's nimble Robot solves a Rubik's Cube in a world record time of 0.38 seconds.

Many people have a special place in their hearts for the Rubik's Cube. This is a good workout for the intellect. Many people loved or still love to play with this ingenious toy, and over the years there have been many competitions, challenges and variations to solve the Rubik's Cube.

The popularity of the Rubik's Cube can be attributed to the simplicity of its design combined with the mind-boggling complexity of the puzzle.

New record for solving a Rubik's Cube 3x3x3.

Engineers and hobbyists have been using robots to solve Rubik's Cubes for years. 10 seconds used to be considered a quick assembly, but by today's digital age standards, that's a time that makes you smile.

It was only a matter of time before engineers and roboticists began to tackle the challenge of creating a new robot. Back in 2016, the robot set a new record for solving a Rubik's Cube in 0.637 seconds. But for some enthusiasts, that time wasn't fast enough.

Just recently, two MIT students, Jared Di Carlo (a third-year electrical engineering and computer science student) and Ben Katz (a mechanical engineering graduate student), thought they could build a faster robot that could solve a 3D combination puzzle.

They watched videos of previous robots, and noticed that the robots' motors were not the fastest that could be used to solve the problem. So they thought they could do better with better engines and controls.

How a robot solves a Rubik's Cube

Students installed an electronically controlled motor that powers each face of the Rubik's Cube. Using a pair of web cameras pointed at the cube, special software determines the initial state of each side of the cube (which colors are on which side of the cube at a given time). Then, based on the information received, using existing software for solving the Rubik's Cube, the robot solves the puzzles using an algorithm.

What is the result of the work? Their robot solved a Rubik's Cube in 0.38 seconds! It is safe to say that no person is physically capable of breaking the record for this speed. We can add another achievement to the list of robots surpassing humans.

There is a man who holds the fastest world record for hand assembly, his name is Felix Zemdegs. He was able to solve the Rubik's Cube in 4.22 seconds. The skills and talents that robots are replacing are vast and varied, to say the least. Not to mention that robots can still surprise. Next is a video demonstration of the robot; it’s better not to blink while watching.

Video review of assembling a Rubik's Cube in 0.38 seconds:

Just like that, hardware hackers Ben Katz and Jared Di Carlo broke the previous record for robotically solving a Rubik's Cube. Their robot solved the puzzle 40 percent faster than the previous record.

Details about the record-breaking robot

The robotic device is assembled from motors from the Kollmorgen ServoDisc U9 series, PlayStation Eye cameras (for scanning the cube) and, of course, a Rubik's Cube was needed. According to the robot's creators, "The entire software process takes about 45 milliseconds. Most of the time is spent waiting for the webcam driver and determining the colors on the sides of the Rubik's Cube."

Facebook Inc. Artificial Intelligence Research Group. presented new platform for robotics called PyRobot. This platform (framework) was developed jointly with researchers from Carnegie Mellon University. PyRobot aims to help AI researchers and students integrate deep learning models built using the PyTorch platform (a machine learning library for the Python programming language) with the robots they create. The basic idea is that they can create their robots more easily by using artificial intelligence skills such as natural language processing.

News from the world of robots with AI (AI): Facebook introduces a platform for robotics PyRobot is an open source framework for controlling robots.

Facebook said it wants to promote long-term robotics research to help develop embedded artificial intelligence systems that can learn more efficiently by interacting with the physical world.

Previously, to stimulate the production of artificial intelligence models, the company introduced PyTorch Hub.

What is PyRobot today

PyRobot is a lightweight, high-level interface that provides independent hardware APIs for robotic manipulation and navigation. The PyRobot repository also contains a low-level stack for LoCoBot, a low-cost mobile manipulator hardware platform (robot assembly toolkit). Now artificial intelligence and machine learning is becoming more accessible to those new to robotics.

Research supervisor Abinav Gupta and Saurabh Gupta, as a research fellow at Facebook, explained in their blog that: PyRobot is a lightweight, high-level interface on top operating system robot It provides a consistent set of hardware-independent middle-level APIs (application programming interfaces) for controlling a variety of robots. PyRobot abstracts away controller details low level and interprocess communication, so machine learning specialists and others can simply focus on building high-level AI (artificial intelligence) robotics applications.

Facebook's source also says PyRobot has dozens of potential applications, such as helping researchers share data and set benchmarks and build on each other's work. The company solicited proposals from the broader AI research community on how to democratize robotics using LoCoBot and PyRobot, which are hardware specifications and tools for building low-cost robots.

PyRobot works by using APIs to abstract the functions that robots need to use. Perform tasks such as kinematics, path planning, position, speed and torque control for joints, and visual simultaneous localization and mapping. PyRobot comes with a number of pre-trained deep learning models that allow robots to navigate, grasp objects, and more.

This means developers can program their robots using just a few lines of Python code, Facebook says.

Facebook researchers also say that: The cost of hardware and the complexity of specialized software limit the scope of robotics research. With lower barriers to entry, researchers can, for example, build multiple robots that collect data and learn in parallel. Providing a common platform for various equipment. PyRobot will lead to the development of benchmarks in robotics, similar to other areas in AI, and will quantify the pace of progress in AI robotics.

Like Amazon's RoboMaker, PyRobot runs as an interface on top of the robot operating system (ROS), extending the infrastructure. In May, technology company Microsoft released a set of robotics tools with a limited preview, and last year integrated the ROS platform into Windows 10.
