Faced with the problem of lack of power when connecting a communicator on Android - with the simultaneous operation of the GPS navigator and DVR, the battery discharges faster than charging. At the initial 100% charge of the battery, even when connected to the vehicle’s on-board network, it goes to zero for several hours of operation in this mode.
Battery problems caused by water damage are also very common. If your phone does not charge after falling into water, you do not have many options, you need to change the battery, if possible, and there is no more serious internal damage. However, you should try to prevent this from happening.
If you find a solution that we have not put together in this article, you can leave us a comment to help other people with the same problems. Whether they are laptops, tablets or smartphones, this type of recording is becoming an extremely popular feature, and not surprisingly. Among these benefits are connector reversibility and a higher data transfer rate and device loading.
At first I decided that the charger used by me lacked an ampere at the output. I bought several more powerful ones (at 1000mA and at 2100mA) - but the result did not live up to expectations, the picture did not change.
I do not have knowledge in electronics, so I would like to hear the comments of knowledgeable people.
Googling a little, I found the following statements that interested me:
However, like all technologies that are at an early stage in terms of adoption, there are certain dangers. However, these risks are associated with ignorance, both among manufacturers and users. Essentially, this resistor ensures that smaller devices do not extract more energy than their circuits can withstand.
But then which cables are safe?
Therefore, it is worth deciding which one is right for you. This cable is one of the best in terms of price and quality. It is able to charge quickly because it has a charging current of 4A. Combine the incredible price with even more incredible features. Made in nylon, it has a length of 1 meter. Despite being slightly more expensive than the previous cable, it has a shield made of Mylar aluminum foil, which provides stability for many years. The connector is nickel-plated and the cable length is 1 meter.
The maximum charging current is the current that, in principle, can be charged. And it will give out exactly as much as the consumer eats. If the device needs 100mA at 5A, then it is 100mA at 5V and will consume even if the source of these 5V will be able to give out 100500A.
As I understand it, it follows that this is not even a charger. The communicator itself consumes less from charging than it spends on working in this mode.
This cable is something special, as it meets the necessary requirements so as not to fry your device, and also allows you to charge at a long distance. In addition, according to the manufacturer, you will not have problems with this cable, because it has a special nylon braid. Each cable has something special that makes it ideal for people with different needs.
You just noticed that your phone is almost flat, but you have little time to recharge it. It's simple: follow these 5 tips and you will quickly get interest! Would you be addicted to your smartphone? Worse, you absolutely need drums because you are waiting for an urgent call and cannot miss it. Fortunately, you can relax with a variety of tips that let you quickly charge your phone.
What is also interesting - in the phone’s properties, when charging from one of the devices, the status “USB charging” is displayed with the other charger “Charging AC”. I assume that in USB mode the phone should consume no more than 500mA, since in USB2.0 the maximum current is 500mA , although this may not be the case. Perhaps the phone determines the type of charging not by the number of amperes, but for example by closed contacts through which information is transmitted to USB, or something like that.
Close all applications
Forget about how to charge your phone through a computer and choose a power outlet. Charging is much faster when the charger is plugged in. Just because it is able to transmit more energy! This is why it is important to close them to speed up the boot process! The same goes for geolocation services and any other useless features running in the background.
In addition, if you want to earn interest even faster, you can even switch to airplane mode. But be careful, you will no longer succeed, because the network of your phone will also be disconnected. Is that all, you all closed and cut off all connections? Now don’t touch the phone anymore!
In total, there are five wires in the USB cable: black and red - power, white and green - data, and the fifth - braid with foil around the perimeter.
I also saw a comment that in order to increase the charging current above the nominal for USB 500mA, some manufacturers supply power to the MiniUSB connector additionally to the 4th pin (through which data is usually transmitted). And what is strange, having disassembled several plugs, I saw myself that in one of them the minus is connected through some kind of transistor to the neighboring contact as well. There are two cores in the auto-charge wire, and in the connector they go to three MiniUSB pins. In others, they are connected to two - red and black wires. In general, this story is also unclear.
If you look at it every ten seconds or use this moment to sort your photos, you will never be able to achieve the desired effect. Indeed, the screen is an element that consumes most of the battery! The more you request it, the longer your phone will load.
In general, when you want to save battery, feel free to dim the screen. You will notice that this gesture allows you to optimize the autonomy of your phone, as well as reduce charging time. Also consider disabling the vibration alert.
I disassembled all the chargers I purchased to evaluate the quality of the filling.
I would like to hear your comments on the device data charges. Get advice on how to get enough power to charge your device.
Candidates for the role of powerful charging:
Ginzy GA-4212UB / S3 - 520rub.
Characteristics:
Output: 5V 2500mA total for 2 USB
And nowhere did I find information about how many amperes and which connector is being fed. It says only one USB for charging Apple, the second for the Galaxy Tab. If they were the same in Amperes, I think they would not sign them. I suppose that one of them is at 1000mA the second at 1500mA, but who is who - apparently they can only show measurements, I have not figured it out yet.
Thus, the rule of thumb for quickly charging your device is to leave it alone! This is the most radical decision! If you do not want to configure your phone settings and close everything manually, you can simply turn it off. You will be sure that it does not consume anything and that it is charging at the best pace.
Specifications
To be sure of optimal use, it is best to start with the right foot and follow some basic rules. If this note may seem obvious, it remains that there are other standards, and looking at the data sheet will not hurt. To have peace of mind, take the standard plug if the cable is lost or broken. Check for an AC adapter. Not all wireless chargers come with a power cable. To avoid disappointment, carefully read the accessories that came with the induction charger. If you already have one, make sure that it can provide the power needed for the charger. Check the total current. Choose a reputable brand. Trusting the induction charge of your phone that exceeds a thousand euros to an unknown brand, the risk is not needed. Select a standard connector. . Finally, obviously, choose the object that you like!
Mobiledata YXT-022 350 RUR
Characteristics:
Output: 5V 2100mA on 1 MicroUSB
Here, all the declared amperes fall on one connector - everything is clear with this. The chip inside looks very rude - a bunch of empty space. thick tracks. it seems that this is done so that crooked-handed workers could participate in its soldering. Even if you poke the wrong soldering iron, you will not damage anything. I think it could be assembled on a half as much board.
If the charger should sit on your desk or on furniture, how versatile is it thanks to the timeless design. From squares to circles, from black to transparent to wooden, there is something for every taste and every color. The power cord design is ideal for preventing conventional charging cable wires. We are responsible for the quality of our products.
- The cable is flexible and can be easily bent to the desired shape.
- The cable has a maximum power of 5 A and also transmits data.
Deppa - 129 rub.
Characteristics:
Output: 5V 1000mA on 1 MiniUSB
On this board, in my opinion, most of the elements are soldered. Even the reverse side was not left without use. I would like to understand if this means a greater number of elements of a more advanced technical filling?
We also think a lot about how much we depend on smartphones. On the graph you can see how the charging process goes with time. Caution, use the original device cables. Do not use random wires for the charger.
Cables with higher resistances exist that can ignite a cable, charger, or smartphone. Smartphones are developing so fast! We could not escape the cliche, because it supports our next statements. Although technological leaps are not always as obvious to the user as we want, they are.
Unknown charge for 55rub.
Characteristics unknown, documentation lost.
Surprised by the lack of a copper coil, which is on all other charges. Is it good or bad?
Based on this chip, I previously made a hidden microUSB wiring for powering mobile devices, as you can read about the post in my logbook.
Unfortunately, they are not doing this right now, and there are no clear signs that this will change. In fact, the technologies have been the same in recent years - only manufacturers are increasing battery capacity or adding and improving special energy-saving modes. Here are some tips to help you deal with fast-paced energy. Caution: This guide is intended for more inexperienced users. If you find additional ways to store the battery, share it with your comments.
It is convenient for all applications to report everything that happens per minute, but it is a big enemy for a modest battery that should bring life to your entire smartphone. Although this is not very convenient, use manual mode. You will quickly see this change, and if you have an important application that needs to be updated in real time, leave it alone.
Smartphones are currently very popular, and so much so that they displaced ordinary cell phones from the market. Everyone is familiar with the advantages of smartphones, but they have one significant drawback. If you are always connected to the Internet, play games or talk for hours - the battery runs out very quickly ... And in order to charge it you need a charger and a wire with a microUSB plug. But not every wire is suitable for charging smartphones, as it does not provide adequate voltage transmission. The choice of a suitable wire for charging smartphones will be discussed in this article.
Do I need to sync your photos with all accounts? Do not deny new versions of applications - there is a reason developers are launching them. Often, among the main reasons, it is the optimization of consumption. It’s important to add - do it when you decide, not the application. Perform updates manually, as the automatic function may choose the most inopportune moment for updating 15 applications with a 10% battery.
One of the most important tips is not to use fake chargers and batteries. In addition to poor quality, they also hide other dangers. Another convenience that, if you can save, will make the battery easier. This feature is a larger consumer than the ringtone itself. The bad news is that it's nice to turn it off when you press the buttons. This is fully applied if you do not use gestures in the air, intelligent page viewing and similar glimpses.
Theoretically, you can carry a micro usb cable with you and charge your smartphone in the office from any computer, or in combination with a power supply from a wall outlet. It is because of the fact that you often carry such a cable with you that most often it is damaged or lost. Such a cable can be damaged very easily, especially if you carry it in a bag or backpack mixed with other things. Also, the micro USB connector is not too durable, because in order to have a mechanical contact of the fields, manufacturers most often use slightly bent contacts. And bent contacts, as you know, after several hundred charges can be unbent, which makes the wire cease to fulfill its functions. 
If they are turned on and you are not using them, you have “guests” who only satisfy their hunger without returning. While we see the vision - get rid of all unnecessary widgets and forget about animated wallpapers - their thirst is strong. Even if you do not update your widgets regularly, just sit on your desktop, they are still consumers. Here, of course, we are talking about those whom you do not use.
A function that sounds more than comfortable and true is not optimal for the battery. Often this makes it easier to display more than you need. The best option is to adjust the brightness to a low but comfortable level, which you can increase if you feel the need.
There is also another problem, these cables are often borrowed by work colleagues or other dormitory residents, and often do not return :).
How to choose a new wire?
In case of loss or breakdown, it becomes necessary to purchase a new microUSB cable. Original, from manufacturers of smartphones or tablets, as a rule are inaccessible, and are sold at crazy prices. Theoretically, every smartphone owner in this situation can buy a cheap Chinese cable. 
Obviously, the best way to extend battery life is to use the widget less. Yes, this is difficult to advise, but you can do something - reduce the time, then the display goes blank. If it is now per minute, do it in 15 seconds - it is 4 times less, and the less battery will be used.
Charge your smartphones when you decide - lithium-ion batteries do not suffer from "memory". It is best to disconnect the phone from the network before it reaches 100% charge, but also try to keep the percentage from falling lower. More active users can use external batteries that provide a reliable charge.
At first glance, the difference between the wires presented is in size, some have 50 cm others 100cm or even more. But that is not the problem. It may appear when you try to charge them a smartphone.
A case is known when, when using the Chinese wire, the smartphone from zero to 88% was charged for 12 hours and at this point it stopped, that is, it was not able to charge it to 100%. At the same time, the owner of the smartphone first decided that this was a smartphone problem, however, by borrowing from the colleague the original wire was able to charge the smartphone in 3 hours.
Silence: for you and the battery
If you don’t have access to your phone at certain times of the day, set a mode that restricts wireless connectivity and mutes sound and vibration. In the absence of such a function, you can put the phone in “Airplane mode”. The bad news is that this will completely limit incoming calls. You can also do this during the day, unless, of course, you always have to connect.
If you use a wireless network when you are at home or at work, leave it always on, and not just when you wake up the phone. Thus, you run out of battery less than the battery, because the network will not connect several times. External batteries are available in a variety of sizes, colors, and configurations, all of which provide ample charge for your devices. But how to choose the best device according to your needs?
After that, he checked the wire by measuring the charging voltage, and the puzzle resolved by itself. So the original wire from ZTE, 60 cm long, supplied a voltage of 4.6 volts - that is, the cable resistance was relatively small. In turn, the Chinese stamping produced a voltage of 1.9v. The cable resistance was so great that the phone practically could not really charge.
The moral of this story is quite simple. It is enough to buy a good quality wire for $ 2 so that you can charge your smartphone without a brake from a computer, laptop or charger. It should also be remembered that not always a higher price implies better quality. Now you know that if the phone charges unreasonably long, the problem is in the new cable, which should be replaced.
