Here, we need to understand a basic concept: decibel - the unit of sound pressure level (symbol: dB), for every doubling of sound pressure, the sound pressure level increases by 6 dB.  1 dB is the sound that the human ear can just hear; generally speaking, 15 dB or less we can consider it to belong to the " silent "; and 20 dB or less we consider it to be quiet.  20-40 dB is about the murmur of a couple's ear. Normal environmental noise intensity in 30-40dB, relatively quiet and comfortable; 40-60 dB belongs to our normal conversation sound, when more than 50dB (45dB at night) may affect sleep and rest, so that the normal physiological function is affected to a certain extent.  Above 60 dB is a noisy range, 70 dB we can consider it very noisy, interfering with normal conversation and communication, making people feel distracted and unfocused.  Above 90 dB (the upper limit of the national noise tolerance) will cause hearing damage and lead to other diseases, and stay in the space of 100-120 dB, if there is no accident, one minute humans will have to be temporarily deaf (deafening).  But there are cases where a high volume speaker is very necessary.  Do not forget that the above data is for normal people, for hearing problems in the population, such as the elderly, they have different needs. It is possible that what we generally consider as noisy sound is just right for them, so a smartphone with a good quality loud speaker can help them hear better.  For some people who work in a very noisy environment for a long time, such as construction workers, the surrounding environment may be more than 70 decibels, then if your phone volume does not reach this decibel or more, it is likely to cause you to not hear or hear clearly, so that you miss some important information or calls. Next, let's look at the results of a test done by GSMArena. Obviously, ordinary smartphones are not able to meet the needs of this group of people for the volume.  In addition, loudest speaker can have a broader use, for example, in the morning you have difficulty getting up, but you have to go to work, you have to go hunting, you have an appointment with friends to go out, especially in winter, wrapped in the blanket feeling really too cozy, ordinary alarm clock and can not wake you up, you begin to hesitate in the wake and continue to lie in bed, you begin to think about whether to change the plan, this time, At this time, if the ordinary alarm clock is replaced by a loud speaker, you will not hesitate to get up, as long as the sound is sounded, you are stimulated, you will quickly jump up from the bed to turn off the sound, this time your sleepiness is completely gone, maybe with the loud speaker, it will not become so difficult to get up. In some extreme cases, smartphone with loudest speaker can even save your life, for example, you are trapped in a place, you need to shout for help, but your voice is too small, and only a few shouts, your throat is dumb, this time, with the power of the loud speaker, may be able to increase your chances of being rescued.  The smartphone with loud speaker is really practical, try to use the loud speaker phone to bring more surprises to your life.

Because of its function and appearance, people have always associated smartphones with young people and rugged phones with old people, but now more and more young people are choosing to use rugged phones.Why is that?I think the most important point is that we are dominated by all kinds of apps, smartphone can install all kinds of apps, but rugged phone only has the most basic functions such as making phone calls and sending text messages due to the limitation of technical conditions. This limits people's access to a wider online world to the greatest extent.I'm a 27 year old, I'm currently using an iphone 8, but I really want to change my phone, I want to try rugged phone, the next is my personal experience, maybe not universal, but somewhat representative.It's really rare for me to be able to spend a continuous hour doing something without being disturbed by other messages. When I'm working, I get messages from people on social media, and work groups often have message alerts, and even though they may not have anything to do with me at all, I still need to take the time to read them. Outside of work hours, my time is more fragmented. One minute I browse through the answers on Quora, one minute I chat with my friends on WhatsApp, one minute I browse on Facebook, one minute I browse shopping sites to see if there is anything I can buy, then I play games, then I browse Tinder to see if there are someone who has hooked up with me, and so on. I seem to be really busy, I have multiple apps to browse, but when I'm done, it's like I'm not browsing anything, but my time is passing while I'm switching between apps. The problem is, I don't get any information that helps me, I don't remember anything, and sometimes I even get some spam and I want to say what the fuck, I've been receiving information passively and I never have a choice about what I want to receive. Wait, I get it, all these seem to be social media apps.But I have to admit that there are some tool apps that are essential, personally, like Google Map, like Uber, like Airbnb, that really have made my travels easier.So to be precise, my life has become more convenient because of tool apps, but also more fragmented and meaningless because of various social media apps.So, at the moment I have two options, first, buy a smartphone, but only download some necessary tools, but as a human, I want to socialize, can I resist not downloading any social media apps? Instantly, I know that once I download this type of app, my time will definitely be divided. The other option is to buy a rugged phone, whether it's a social app or a tool app, I can't download it. I seem to be relearning how to live without my smartphone.

Infrared thermal imaging technology is a passive, non-contact detection and identification technology, can use the target and the background or between the target parts of the temperature difference or radiation differences in the formation of infrared radiation characteristics of the image to find and identify the target, its two basic functions are temperature measurement and night vision.Thermal imaging camera works on the principle of thermal infrared imaging technology. Modern thermal imaging devices work in the mid-infrared region (wavelength 3 ~ 5um) or far-infrared region (wavelength 8 ~ 12um). By detecting the infrared radiation emitted by an object, the thermal imager produces a real-time image, thus providing a kind of thermal image of the scene. Its core is a thermal imaging camera, which is a sensor capable of detecting very small temperature differences, the temperature difference into a real-time video image display. But only see the thermal corridor of people and objects, can not see the real face of the object. Advantages 1, day and night can be used normally 2, extreme weather can be used 3, can see through the fog, rain, smoke and other obstacles 4, all heat-generating objects are nowhere to hide in nature as long as the object above absolute zero (-273 ℃), will be constantly outward radiation of infrared. Thermal imaging that is through the optical system, infrared detector chip and electronic processing system, the object surface infrared radiation into a visible image. Simply put, the principle of thermal imaging is to use temperature imaging to transform the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.Thermal imaging is not affected by visible light, can be 24 hours clear imaging, non-contact temperature measurement, through the smoke and fog and other advantages, can be applied to human temperature measurement, industrial temperature measurement, automatic driving, security fire, outdoor observation, etc.. Commonly speaking, thermal imaging camera is the invisible infrared energy emitted by the object into a visible thermal image. The different colors on the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heat generation of the target can be studied to provide a basis for work and research. For example, the infrared thermal imaging camera can check the floor heating leakage, can accurately detect the indoor pipe network, such as the distribution and direction of the location of the floor heating pipes, water pipes, hot water pipes, and can accurately locate the location of pipe leakage. Underfloor heating leaks often exist in two phenomena.1. fuzzy diffusion of pipes at the leaky location, the storage of non-linear, presenting a cloud of heat in the infrared picture.2, the leak location temperature is high, in the infrared picture presents a white bright color.The main performance indicators of thermal imaging night vision device classification. 1. resolution: resolution is the assortment of thermal imaging night vision device is an important indicator, night vision device affects the cost of thermal imaging night vision device one of the keys. General thermal imaging night vision camera resolution of 160x120, 336x256 and 640x480 three. The selling price from tens of thousands to hundreds of thousands of dollars.2. the resolution of the built-in screen: we observe the target through the thermal imaging night vision device, in essence, is to observe its internal LCD screen. The top thermal imaging night vision device, its built-in screen resolution and clarity are very high, so that it is clearer observation effect and better vision.3. magnification: due to the technical bottleneck, the physical magnification of the thermal imaging night vision device, at present, the largest magnification can be produced for 5 times. 4. double tube or single tube: double tube in the use of comfort and observation effect are obviously far better than single tube, of course, the price of double tube thermal imaging night vision device will be much higher than the single tube thermal imaging night vision device, double tube thermal imaging night vision device in the production technology will be much higher than the single tube.

Recently, a friend came to me complaining that his recently purchased cell phone screen was broken, coincidentally, he did not buy a broken screen insurance, and eventually spent a lot of money to replace the screen. I was thinking that if my friend had bought a Rugged Smartphone, there would not be such a problem, but why has the Rugged Smartphone, which is waterproof, dustproof and shockproof, not been popular? Why is it only a niche category in smartphones? Why only a specific group of people will use this type of phone, such as construction workers, hunters, outdoor enthusiasts, etc.?First of all, people's impression of Rugged Phone is still stuck in a very long time ago, when talking about Rugged Phone, the first image that comes to many people's mind is Nokia 3310, which is indeed a kind of Rugged Phone, more precisely it is a feature phone, don't forget, there is also Rugged Smartphone. You can understand the Rugged Smartphone in this way, it combines the indestructibility of a feature phone with the intelligence of a smartphone.The second is that it is not as good-looking and light as ordinary smartphones. The fact that the Rugged Smartphone does not look good is not entirely the fault of the designer, but a major reason is the limitation of engineering materials. Today, the phone to do waterproof and dustproof is not a difficult task. To achieve this goal, there are usually two options. One is by reducing the splicing of the body, and then use the waterproof tape and seal to block the body gaps, making the body waterproof, dustproof ability greatly increased. This is the idea of structural dust and water resistance. This sealing method also has many drawbacks, such as headphone holes, charging holes on the rubber plug deformation, it will destroy the phone's sealing, resulting in a decline in the ability to waterproof and dustproof. This will require the use of nano-waterproof technology. Simply put, the device surface is coated with a layer of nano-polymer, liquid and coating contact will condense into water droplets rolled off, so if there is liquid into the device, you can quickly discharge. For rugged smartphone, these two options will basically be used at the same time. In the body of the charging hole, headphone hole parts of the rubber plug, although waterproof, mud-proof, but pulled down the body of the sense of sophistication. Another reason to reduce the beauty of Rugged Smartphone is the thick bezel. In order to prevent falls, rugged smartphone mostly use armor-type protective structure, the bezel is made thick and large, and the material mostly uses soft rubber to improve the toughness. Finally, the rugged smartphone currently have some features that may not be particularly practical for many people, for example, thermal imaging camera, loud speaker, accurate coordinate positioning in the absence of card and no signal, these technologies may only used by a specific group of people.I think these are the main reasons for the Rugged phone is not so mainstream, what do you think?

First, we need to know what extreme cold is. According to the Department of Emergency Management and Safety Services, extreme cold can be considered any temperature below the freezing point (32 degrees Fahrenheit).When the temperature drops low enough, you'll notice all sorts of problems with your phone: Sluggish response! Crazy battery drops! Dead phone! It simply shuts down! At this point you think it's the quality of the phone that's at fault, but in reality you don't know it's the low temperature that's to blame.Smartphones are generally installed with lithium batteries, which work on the principle that the internal electrolyte through a chemical reaction, the formation of potential differences, thereby generating current. In low temperature environment, the chemical reaction of lithium battery slows down, so the discharge current becomes smaller and the power drops. And when the phone turns on the battery low temperature protection, there may be automatic shutdown phenomenon. The iPhone has a clear statement on the official website that the normal operating temperature is 0~35℃; the best use temperature is 22℃; and the limit temperature is -20~45℃. Of course, we know that iPhone work less than normal when they are close to about 0℃! So, what about Android phones? In fact, it is similar. So in winter time, or colder areas, the use of cell phones can easily cause problems, and in some more extreme cases, your life will be threatened. For example, snow climbing, you encounter some special situation, you have to seek help, if you bring a normal phone, it is likely to automatically shut down long ago, so in similar situations, we need an unusual phone, this phone needs to be able to maintain normal operation even in extreme cold conditions. This unusual phone is the AGM Glory Pro, I am proud to say that with AGM Cold Resistant Battery, the phone can be used continuously for 22 hours at -27°C, 10 hours at -30°C and one hour at -40°C.Why is AGM Cold Resistant Battery unusual?1, Heat Protection SystemWith the redesigned structure, Glory will prevent heat evacuation under cold environments. All generated heat will be delivered across the components, boosting the cold resistance of the inner structure. 2, AGM Battery ActivationThe vitality of any lithium battery will decay under extreme coldness, with the AGM Battery Activation Solution, Glory's lithium battery will remain vital under -27°C. Proven by the Thermal Shock Test, AGM Glory is also adaptive to 60°C and other tough situations.

I have done a user research before, mentioning "what do you think of when you hear rugged phone", I was surprised that many people mentioned Nokia 3310, the research address is as follows, https://bit.ly/3A5OV8S, This is indeed a model of rugged phone, we can devide rugged phone into 2 categories, feature phone and rugged smartphone. The rugged smartphone has been developed over a long period of time, and now its functions are more powerful than those of ordinary smartphones. I can say this, as far as the function is concerned, rugged smartphone can completely replace the ordinary smartphone, but the ordinary smartphone can never replace the rugged smartphone.AGM is a professional manufacturer of rugged smartphones, I'll take AGM Glory Pro as an example. The following features are not available on ordinary smartphones. Glory Pro is IP68/IP69k/MIL-STD-810H certifiedThe IP Code denotes the degree of protection provided by your device's internal casings and enclosures against dust, intrusion, and most importantly water. IP68-rated machine can go up to 1.5m for the same amount of time, IP69k means that the phone would be able to withstand high-pressure, high-temperature jet sprays, steam-cleaning, or washdowns. Arctic Battery/ Cold Resistent BatteryThe Glory Pro can be used continuously for 22 hours at -27 degrees Fahrenheit, which is a very powerful feature. In more extreme conditions, many phones will fail, but not the Glory Pro.Thermal Imaging TechnologyAGM Glory Pro phone thermal imaging technology is the industry's top, with twice the resolution and 1/2of the reaction time than the best phone thermal imaging in the market.Measures all objects within 5 meters.Industrial Mode Accuracy: ± 2.0°C, ranging from rather -20°C ~ 150°C, or 100°C ~ 550°C.I just gave a few examples, there are many other features that are not available in a normal smartphone. If you want to know more, you can come to our website and have a look.

This is a screenshot I took from our website.There are a lot of words on it that people who are not in the professional field may not necessarily understand, so that they don't know how to pick the right phone for them. Next, AGM Mobile will explain these similar proper nouns from a professional perspective so that you can pick the right phone for you.1, What is Qualcomm Snapdragon?Qualcomm Snapdragon is a processor, and many people know that the processor is the core of the phone. Now the high-end processors are Snapdragon 865, Apple A13, Kirin 990, etc., while the mid-range processors are Snapdragon 7 series, Kirin 820 and other processors. The better the processor of the phone, in general, the more smooth the phone. But the better the processor, the greater the corresponding power consumption, the phone is easy to heat up.2, IP68/IP69K/ What does it mean?Here IP is the abbreviation of Ingress Protection, the IP Code denotes the degree of protection provided by your device's internal casings and enclosures The IP Code denotes the degree of protection provided by your device's internal casings and enclosures against dust, intrusion, and most importantly water.As per IEC standard 60529, IP is always succeeded by two digits. If we take IP68 as an example, the first digit (tens), 6, denotes protection against dust, If we take IP68 as an example, the first digit (tens), 6, denotes protection against dust, while the second digit (units) signifies protection against prolonged immersion in water.For a detailed guide, have a look at this picture:So IP68-rated machine can go up to 1.5m for the same amount of time, IP69k means that the phone would be able to withstand high-pressure, high-temperature jet sprays, steam-cleaning, or washdowns.

Before understanding these two parameters, we first need to know what ROM and RAM are. ROM means Read Only Memory, which means this kind of memory can only be read, not write. ROM and RAM are both a storage technology, but the principle is different, RAM for random storage, power failure will not save data, while ROM can be in the case of power failure, but still save the original data.We all know that there is memory and hard disk, in fact, memory is a RAM technology, while ROM is similar to hard disk technology. In cell phones, RAM refers to cell phone memory, which belongs to the internal memory of the phone and belongs to random storage, which plays an important role in determining the performance of the phone configuration. In addition, after a power failure, the data is cleared and the software is not in the login state after restarting the phone.ROM belongs to external storage, for example, we can often buy SD cards to put inside the phone, cell phone ROM is what we usually say memory card, can also be simply understood as cell phone hard disk. It is used to store phone system files, pictures, movies, etc. It will not lose data when the power is dropped, and the larger the ROM, the more data will be stored.Here 8GB is the parameter of RAM, 128GB is the parameter of ROM. In cell phones, RAM refers to the phone memory, for cell phones to see the performance, in addition to look at the phone processor is to see the memory, the larger the memory phone configuration is better.The larger the ROM, the larger the phone can store things, the larger the capacity, the more expensive the phone is generally, many phones of the same model different versions are divided by the ROM capacity. Take AGM Mobile as an example, the same phone model can be divided into 8GB + 128GB and 8GB + 256GB, the latter will be more expensive than the former.

Greetings to the guys from AMG, I am from sunny (sarcasm) Yakutia, Nyurba The story of turning off the phone in our region is not news, so let's say, I personally have tried a bunch of different companies of smartphone models until now I have not met the one who would have met my expectations straight, so I saw your phone on the YouTube channel of my countryman "Oles Petrovich". At the moment, I use a smartphone from Xiaomi in the cold after 5-10 minutes, if the floor of the screen starts to flicker, and then the accumulator starts to drop to 0%, and then a complete failure only if it is thoroughly warmed during in the inner pocket for half an hour, then it will only work and such phone shutdowns happen everywhere and always, whether it's hunting, at home, on the street, even when photographing under the Christmas tree, it's not possible to tell exactly one story about this.  And I would also like to add off-topic, but I saw on your device there is a thermal imager, a rangefinder, frost resistance, it would all help me at work, i.e. as I myself work in the fire department, a phone with a thermal imager and does not. I'm a hunter. Not a pro, but I love it and try to get into the woods whenever possible. My old Lenovo smartphone is about five years old. So when I'm on the grounds, I always send the point (coordinates) to my wife, just in case. On that day, the thermometer dropped to -20 degrees Celsius. I took my husky, put on a backpack, a gun, and our camouflage in the car, and we set off. The field greeted us with fabulous beauty. The trees were coating snow velvet and sparkling under the sun. The snowball crunched merrily underfoot. Naturally, I took out my smartphone to take off this beauty. However, it took only one photo before the screen blinked out. So I thought, how would our heroes cope with this? I put it in my shirt pocket closer to my body to warm it up. Half an hour later, I got it! Oh! Great! It revived!  I got some more photos and ...the screen went black again.  In general, I made a couple more pictures according to this scheme, and my Lenovo refused to wake up. When the sun told me it was evening, I heated my car and gadgets.   I was finally able to call my loved ones again. In the end, everything ended well. Well,  It was upsetting when I walked back into my memories. We lost all the communication, and what if there was a car breakdown or something? Today, everyone who was missing left the apartment without a phone.  That's the story.  Thanks for your attention. The tale of How did a cold smartphone fail me in the "rescue operation"? To begin with, I'll tell you about my current phone for the sake of fairness. I have a Samsung J7 model year 2016, bought in 2018 specifically for working in a taxi. The seller recommended it as one of the most suitable at that time. He worked hard accordingly(navigation, geolocation, Internet) and constantly charged, affected its battery life.   On the paper, it was a 3300 mAh lithium battery.  Video playback time? Up to 22 hours.  Network operation? Up to 11/14/15 hours (3G/4G/Wi-Fi).  Naturally, at the time of history, the battery was no longer holding up to its glorious past. Then a year later, I broke the screen, but I never changed it. I was not clear how it would affect me, but you never know.    It happened on February 14, 2021. I can easily recall the date because it was Valentine's story. I was a member of the volunteer community of free assistance on the roads and off-road. On Sunday, an application for passenger car evacuation in the suburbs of Kazan fell into our "alarming" chat. I live on the nearest outskirts, so I accepted and enforced my mission.    It turned out that a young guy decided to arrange a romantic picnic for his girlfriend in a field next to the radar that serves the airfield of our local aircraft factory. The idea was great, a barbecue, kebabs and bombers, fighters, and other missile carriers flying overhead. The guy acted reasonably, and he even checked the field the previous day.  However, on the next day, the weather changed – a sharp cold snap to -20 degrees celsius, and he could not get there to prepare everything on the spot. I drove to the place, met the applicant, and went to look at the stuck car. I couldn't get to him in my vehicle because of the front wheel that went down very badly at the wrong time. I had to call for the help of a teammate on a four-wheel-drive Kia Mojave. First, they pulled out my car because it blocked the exit on the only road. The rescuing process was delayed because of the snow captivity. As I said, the frost was getting stronger, and the sun was setting while the wind was rising. All this has never helped our business. Meanwhile, my smartphone warmed up a little in my pocket and allowed me to take some pictures of the evacuation results - three beautiful cars and drivers standing against the airfield radar. But for some reason (perhaps because of the dead battery) these photos have not been sent. It was very disappointing and annoying to waste so much effort for nothing. We missed the opportunity to tell our teammates about it picturesquely by providing photos and videos. However, especially for the sake of a good story and to meet the conditions of the competition, I rolled into this place and tried to take beautiful photos. In the photos, I am wearing a black jacket. The background is field and radar.   The applicant then told us that all these troubles (the breakdown, of course) disturbed his big day. The evacuation took about 2 hours. With all the winds running through frosty fingers, maybe it was a bad idea to have a lovely barbeque and kebabs when the field was closed to -20 degrees celsius, even under the warmest clothes.
