You can play the phone while it is charging. Can I use my phone while it is charging? Using power bank

Modern telephones have long ceased to be just a means of communication. Devices that can only receive calls remained at the beginning of the century, and today a smartphone is an irreplaceable thing, the importance of which in everyday life is difficult to overestimate.

Internet access, navigation systems, as well as millions of applications for leisure, business and development have made smartphones the “right hand” of a successful businessman, and an ordinary student, and a schoolboy, and a young mother, and even a pensioner.

And then he ran out of battery ...

Yes, if the great-grandfathers of modern smartphones could do without recharging for weeks, and some even months, modern devices cannot boast of such a thing. Of course, you can always turn off the Internet and navigation, not use applications and achieve almost the same result on some models, but ... wouldn't it be easier then to give up your smartphone altogether? After all, its main advantage lies in its extensive functionality.

Modern smartphones are produced with 2000-4000 mAh batteries. It is easy to guess - the higher this figure, the longer the device will not require "food". But even the most powerful batteries last for a maximum of two days - more accurate indicators directly depend on the degree of use.

A "sat down" smartphone turns into a beautiful, but, unfortunately, useless piece of plastic or metal, and left without a connection, a person literally begins to feel helpless. After all, his phone has access to work mail, materials for the conference, and a shopping list, and a number to call back in fifteen minutes ... It is not a problem to restore the workhorse to work if you have a power outlet or an external battery at hand. It is hidden in something else. For some reason, almost everyone forgets that using the phone while charging is strongly discouraged.

Why can't I use my phone while charging? Battery features.

99% of smartphones today have lithium-ion batteries. They are cheap enough, lightweight and do not require a long charge. However, you need to take into account some peculiarities.

When powered from a mains source, a strong heating occurs. And if you use your smartphone at the same time, it will get even hotter, which can lead to swelling of the battery. The situation is aggravated if the phone is packed in a tight leather case.

But bloating is not so bad. A damaged battery can eventually be replaced. The situation is much worse when overheating of the battery leads to an explosion. Such cases are very rare, but they are known. This is why some airlines prohibit the carriage of lithium-ion batteries.

Overheating also threatens to reduce the service life, and the charging time will increase significantly. And if you use an adapter and a cord from another device during “feeding”, you will most likely not be able to work on the phone - the touch screen will “shut down”, sending a signal to any point, but not where your finger touched.

Safety engineering

But do not refuse to recharge phones "on the run"! Of course not. The modern pace of life will simply not allow this. If the device is charging, and you urgently need to access the Internet, check your mail or write an SMS, for the duration of use, you just need to disconnect it from the wire, and then continue charging. And in any case, do not bring the charging phone to your ear! Cases that he can really do harm are, in fact, rare, but why risk it over trifles?

There is one more interesting "trick", which will definitely be appreciated by connoisseurs of fast charging.

Phones based on Qualcomm and MediaTek chipsets support fast charging technology. You can find out if there is this function in a particular device from the instructions - the words "Quick Charge" or "Pump Express" correspond to it. Such devices can be charged 2-4 times faster. However, to do this, you need to find a charger on the market that supports this technology.

Long and trouble-free operation of your gadgets!

Is it a bad idea to leave your smartphone on charge overnight? This is by far one of the most pressing questions we could ask.

We've all done this: before bed, you connect your smartphone to a charger so it can charge all night while you sleep. The idea is to wake up in the morning with a smartphone battery 100% charged. But then you heard that when the phone charges overnight, it damages the battery and over time, its capacity decreases, so you turn to Google for answers.

Therefore, before we talk in detail about this myth - about charging the battery at night, first we will give you a short answer. Yes, you can leave your phone on overnight. A certain amount of care must be taken, however, so be sure to read on to find out the whole truth about whether you can leave your phone charging overnight. We've also compared pros and cons to help extend smartphone battery life.

Lithium vs Nickel

You probably know that most of today's technology runs on lithium-ion batteries. A few years ago, batteries were mostly made of nickel, like the Duracell and Energizer batteries you buy in stores. Nickel-based batteries tend to have cyclic memory. If they weren't given full charges between cycles, they could “forget” their full power and only remember that they were last charged to their maximum capacity (even if they weren't). Many of us have never used nickel batteries on mobile devices since the switch to lithium ion occurred in the early 2000s.

Fortunately, lithium-based batteries did not suffer from the “memory of charge” phenomenon often exhibited by nickel batteries. Lithium batteries have played a large role in the mobile phone revolution. First, they can hold a lot of energy while remaining fairly compact, which allows mobile phones to become ever smaller and thinner. In addition, lithium batteries have a significantly longer lifespan and charge quickly. One warning is temperature sensitivity.

Heat: the silent (battery) killer

We have now learned about the most significant threat to our lithium-ion or lithium-polymer battery, which is heat. Sure, batteries hate cold in much the same way they hate heat, but the latter is more relevant when it comes to leaving the phone plugged into the charger overnight.

The charging temperature of lithium-based batteries, that is, the temperature at which the battery is able to receive a charge, is between 0 and 45 degrees. Lithium-based batteries, meanwhile, can discharge in temperatures as low as -20 degrees. Fast charging technologies work best at higher temperatures between 5 ° C and 45 ° C; at 0 ° C, charging will stop.

There are several important points that these numbers show us. First, a lithium-based battery can discharge in sub-zero temperatures, so storing them in the kitchen freezer will not prevent them from self-discharging. Second, the lithium-ion battery heats up as it charges. When it gets hot, it charges faster. But since the battery cannot hold more than its capacity, after reaching a full charge, the battery uses up excess power, giving it off as heat. Overnight charging becomes a problem when the battery is unable to redirect the incoming current after reaching its capacity.

Fortunately, there is a solution to this problem.

Smartphones use the battery wisely

The batteries used in mobile devices today are still largely the same as for nearly two decades, but the devices that use them have gotten a lot smarter. Nowadays, we can worry less about when it comes to battery "health" because the problem of optimizing power has been put on the shoulders of the software running on smartphones.

Thus, we get the answer to our main question: can we leave the smartphone plugged into the charger overnight? The answer to this question sounds confident, why not?

As we said above, the main danger of leaving the smartphone on for charging overnight caused the battery to heat up, and it remained hot until the end of the night. However, our mobile devices have become much smarter. They may stop charging when the battery is fully charged, so when you wake up in the morning, the battery is already fully charged overnight. It's pretty nice.

However, this does not mean that the habit of leaving your phone on overnight will not affect battery longevity. You don't run the risk of overheating your battery by leaving your phone plugged into a charger overnight, but we'll still give you some tips you can incorporate into your phone charging habits to keep the battery tip-top.

1. Each lithium battery can have a finite number of charge and discharge cycles. With each cycle, the battery capacity decreases slightly, so we need to avoid a lot of cycles. To do this, try to keep the battery level between 40 and 80 percent. Of course, this will not always be possible, but try not to let your phone charge below 40 percent, and keep the number of full discharges to a minimum.
2. Try not to use fast charging every time you charge your phone. Most fast charging systems cause the battery to heat up, which we know is bad for your battery. If you use the fast charge option frequently, the battery is getting excess heat more often than it should, resulting in a shorter battery life.
3. We mentioned earlier that lithium ion batteries do not suffer from the cyclic memory of nickel batteries. While this is true, the smartphone's internal power meter - the part that determines the current battery power level - can sometimes be reset. You can recalibrate your battery by doing a full discharge and charge cycle: use your phone until it dies. Once it turns off, charge your smartphone to full power by leaving it off. Finally, turn the phone back on and make sure the battery is shown as fully charged in the notification bar; if not, turn off the power and continue charging. Repeat this process once a month to ensure your battery is performing optimally.

Conclusion

The battery is one of the most important components of a smartphone; after all, a smartphone with a dead battery is little more than a paperweight. Therefore, it goes without saying that we do not want to do anything that could damage the battery and reduce its efficiency. While there are those who still believe it is a bad idea to leave your phone on overnight, all signs point to overnight charging as a completely legal way to make sure you start your day with a full charge on your smartphone.

One of the most common problems with which owners of gadgets come to the service center is when the phone starts working only on charging. Moreover, the options may be different:

• The smartphone does not function without connecting to a 220 V network (using an adapter). As soon as the power begins to flow, the logo (Android or the manufacturer of the equipment) lights up, a vibration response is felt, but there is no subsequent reaction - the phone turns off again.
• You can work with the gadget only when it is charging. The icon of a charging battery is lit on the screen, but this does not give a result.
• The smartphone does not recognize the charger (charger), but it turns on only when connected to a power source via a micro USB cable.

In this article, we will deal with all the possible reasons for this behavior, and give practical advice on how to behave in such a situation.

The most common and obvious reason is battery failure. It breaks down more often than other parts, and has a limited shelf life. In addition, it is the battery that is most susceptible to mechanical damage after falls, and also suffers from moisture and debris.

Therefore, you need to handle the battery with extreme caution, adhering to all operating rules.

Remember how long the battery has been in the device? If this period is more than a year, then it is likely that it has already gone through all the charging and discharging cycles (300-400 cycles), becoming unusable. It is useless to revive it - it will be cheaper and easier to buy a new one.

There is a possibility that after mechanical impact (shock, pressure, etc.), the battery contacts are bent or come off. You can correct them yourself, but it is better to contact a specialist.

Often, owners of cell phones come to service centers, in which the battery is no longer charged due to oxidized contacts. This happens if you regularly take your phone to the bathroom, bathhouse (or other rooms with high humidity), use it in the rain and succumb to sudden changes in temperature. In such a situation, the battery will also have to be replaced.

Charger

Pay attention to the charger:

• Examine the cord for kinks and protruding contacts. Careless behavior with a fragile cable can provoke mechanical damage, as a result of which the smartphone will not receive the necessary 5 volt power on charging.
• Examine both connectors (USB and micro-USB). Mishandling and storing their prong contacts can bend and dirt and crumbs can build up inside.
• Check the adapter and test it with other cables.

The system itself, or rather the voltage controller, can also turn off the charging if non-certified cheap Chinese equipment is used in the power supply process. It not only breaks down quickly and does not deliver the promised voltage, but it may well burn individual parts of the smartphone due to poor assembly and inductive emissions.

If the problem with the phone happened on a one-time basis, it is quite normal for the system to malfunction. Disconnect the device from the network. After disconnecting, try charging again.

On / off button

This problem belongs to the category of mechanical damage, when the power button, for example, after a fall, is not pressed, or does not respond properly. It is very difficult to diagnose and repair the module on your own, and for repair you will need special equipment to replace the loop or other components.

Mechanical damage

Breakdowns of this kind occur due to careless handling of the gadget. Falls from a height, testing at extremely low and high temperatures, swimming in water, etc., provoke breakage of parts.

Only the battery can be replaced at home on your own, the rest of the repair should be entrusted to a qualified technician. Sometimes the owners do not even know about such problems, because some blows do not even leave scratches on the screen, but break internal contacts, boards and parts.

It is necessary to try to reboot the smartphone, to do this, simultaneously press the "Power" + "Volume Down" keys and hold them for 7-10 seconds. This is a compulsory procedure that allows you to reanimate the device in case of any errors in the Android system. In 90 percent of cases, the method will work with a bang.

Reset

If this does not help, you will have to roll back the operating system to factory settings. Please note that this will entail the deletion of all personal data and applications, so we strongly advise you not to skip the first paragraph of the instructions:

1. Create a backup copy of all information not smart. Move it to the cloud or physical media.
2. Open the menu or directly the "Settings" section.
3. Find the "Backup and Reset" item.
4. Select the sub-item "Data reset".
5. After rebooting, turn on the equipment and test the charging again.

If the firmware rollback did not help, then the matter is not in system failures, but in the hardware itself.

Installing updates

After installing updates, problems of various kinds often arise, including with the autonomous operation of the smartphone. First of all, the gadget should be simply rebooted and try to charge it again.

Conclusion

Practice shows that in 98% of cases, the situation when the device turns on when charging is connected and is no longer solved successfully and with minimal financial costs.

However, if you are not sure that you will do everything right to solve this problem at home, it is recommended to visit special repair points, where such a problem will be corrected within a few hours or days.

No, this is not about the morning physical routine of the owner of the phone, who decided to check his mail while standing in the bar. It's about charging a smartphone battery.

The usual battery of an average mobile phone is hardly enough for a day of active use. You have to charge in broad daylight, sometimes in the midst of communication. How can you leave your phone alone for two hours? He will be torn apart by messages. Or not from messages? ...

“The question is controversial. The myth that it is impossible to use a phone while charging has gone from old phones. The efficiency of the then batteries directly depended on the charging cycles. If it is charged during use, the cycle does not occur, hence the battery will gradually die. Modern batteries do not depend on this, and the phone can be safely used while charging.

Yes, it gets warm, but it's okay.

The power controller and processor can withstand very high temperatures up to 150 degrees and above. Another thing is the comfort of use, as well as the conscientiousness of the manufacturer. Elements of high-quality assembly are distinguished by good heat transfer and a high melting point of each part.

Chinese budget models do not guarantee that the plastic will not melt inside, that the board or any other part of the device will not be damaged.

Here's an example of using low quality plastic. The damage is not critical, but there was melting, which means the owner inhaled toxic fumes at least:

It should also be noted that there is a risk of mechanical damage to the charging socket. Attachments of the same micro usb to the board are easy to accidentally tear off by pulling the charging cable at a certain angle.

This is the most common problem with which people go to the service center.

It is treated by replacing the connector or re-soldering the old one. It costs from 500 to 1500 rubles, it implies the obligatory disassembly of the device with removing the board from the case. Considering that many modern phones are disassembled through the display sticking, the usual, from the point of view of the master, work of replacing the power connector turns into a rather labor-intensive business with a high risk.
