Almost all new smartphones suffer from one problem - they discharge too quickly. Many users recall with nostalgia those times when the mobile phone "held a charge" for almost a whole week. That's the price you pay for ever-increasing power and performance.

In such a situation, the question of how to properly charge becomes more relevant than ever. new smartphone?

Each of us has probably heard that a new mobile phone needs to be charged in a special way so that the battery subsequently holds a charge longer. Given the above problem and the rather high cost of modern smartphones, I want to save myself from any problems.

Even in the store, the sales assistant usually mentions how to charge the phone after purchase. You can also find entire instructions from manufacturers and various specialists about what needs to be done.

The following advice is most often expressed:

The phone needs to be allowed to work for a while, and then fully charged;
3 complete charge/discharge cycles required;
· After purchase, the phone must be immediately planted, and then charged for 12 hours.

From this it is already becoming unclear, since how to charge new phone? Do I need to "bleed" the battery? And what actually to do so that it does not take six months or a year to change the battery?

Battery features

The bottom line is that batteries, like the devices themselves, are constantly being improved, so the characteristics and requirements for operating conditions are constantly changing. And the advice, in turn, remains the same.

Before you take on the "pumping" of the battery or put the phone on charge for the whole day, you should find out what type of battery is installed and what recommendations the manufacturer gives.

Battery types

The battery is an important part of any mobile phone, just behind the design, performance and other new "chips" they are usually forgotten about. Engineers of the world's leading companies, in turn, are working to improve mobile batteries.

There are several varieties:

· Ni-Cd (Nickel-cadmium);
· Ni-MH (Nickel-metal hydride);
Li-ion (Lithium-ion);
Li-Pol (Lithium polymer).

Nickel-cadmium and nickel-metal hydride batteries were used in older devices. If you still have a tube with a monochrome or simple color display, then it probably has Ni-Cd or Ni-MH on it.

They differed enough a high degree reliability and durability, but very high power. There was another drawback - the "memory effect". Over time, the structure of the electrolyte changed, so it was recommended to fully charge and discharge it at least from time to time.

This is where the advice about charge-discharge cycles came from.

Nickel batteries were replaced by lithium batteries - Li-ion and Li-Pol (lithium-ion and lithium-polymer). They are used in almost all modern smartphones, laptops and tablet computers. Therefore, you need to know how to charge a new smartphone with just such a battery.

Their advantage lies in small sizes, sufficiently high power and safety. They have almost no "memory effect", so they do not require any charge-discharge cycles. Now developers are still working on improving these types of batteries, trying to increase durability and reduce dependence on various conditions operation.

Tips on how to charge your new smartphone

As already mentioned, the batteries of modern smartphones are practically independent of any operating conditions - manufacturers are constantly working on this. Although it cannot be said that they manage to do it 100%. In this regard, certain problems sometimes arise, and some of them arise precisely because of ineffective recommendations.

There are a few tips to follow:

Lithium batteries are sensitive to low temperatures so it is not recommended to use smartphones for a long time outdoors in winter, and it is better to wear them in inner pockets;
· For lithium batteries extreme states are not very useful - full discharge or full charge, so it is better to leave a few percent;
· The optimal state for lithium batteries is 40-60% charge, in this state they are stored without problems for quite a long time. That is why in stores the charge of a new smartphone is always at this level.
Thus, there are no particular difficulties in how to charge a new smartphone. You should not "drive" it on a full charge - this is just not very useful for him. Do not leave it in the cold for a long time, otherwise AB may lose its potential. Although new models are usually made not so susceptible to low temperatures.

It is always better to have a standard charger, USB cable or auto charger with you, and recharge periodically during the day if possible. If it is possible to connect to a laptop or an outlet for at least 20-30 minutes, then this is already enough, and most likely, the smartphone will not sit down at the most inopportune moment.

If necessary, you can purchase a high-capacity battery or just have a spare with you. In this case, you can save yourself from a lot of problems, and not be among those who constantly complain about a discharged mobile phone.

The topic of proper charging of smartphones and operation of batteries mobile devices as old as the world, but still people are arguing about how best to do certain things so that the battery lives as long as possible. There are countless operating tips on the internet, but too much information is just as bad as too little. Due to the many tips and rules (and not all of them carry the truth), users are lost and sometimes begin to follow stupid instructions that have no connection with reality. As a result, it seems to a person that he is doing everything right, but in fact he is killing his battery and reducing the life of the smartphone itself at times. We went the other way and thoroughly studied the topic, so we will try in an accessible form and briefly talk about the main provisions for properly charging a smartphone to increase its service life.

What types of batteries are used in modern smartphones?

Absolutely all fresh smart phones use only one of two types of batteries as a power supply: Li-Ion or Li-Pol. These batteries have many disadvantages, but today nothing better exists yet. Global manufacturers are actively working in this direction and there is already a graphene battery, however, it is very far from mass production. Therefore, apart from the above types of power elements, there is nothing. So what are Li-Ion and Li-Pol batteries most afraid of and which ones have disadvantages:

1. Recharge - reduces service time;
2. Overdischarge - completely disables the battery;
3. Overheating - reduces service time;
4. Subcooling - reduces service time;
5. A limited number of charge / discharge cycles - upon reaching a certain figure, they lose much in capacity;
6. Aging - eventually the battery just dies.

Now let's take a closer look at all the shortcomings and what the neglect of the rules of operation can lead to.

Overcharge is an excess allowable voltage on the battery, which may even result in a battery fire. However, all modern batteries are protected from overflowing with energy due to the presence of a charge controller in the batteries, which, when the design voltage level is reached, turns off charging. The operating voltage varies from 3.5 to 4.2 Volts, while overdischarge is considered to be an excess voltage on the banks over 4.3 V (in some cases 4.35 V). If the battery itself is serviceable, then overcharging does not threaten it and it will never happen. That is why you can safely leave your smartphone on charge all night, because the electronics monitor the process very carefully.

Overdischarge (deep discharge)- observed when the voltage on the batteries reaches below 2.8 V. Overdischarging is no less harmful to the battery, like overcharging, though not dangerous to human life. With a deep discharge, irreversible processes occur and the battery capacity is very much lost. Each overdischarge reduces the battery capacity by 2-3%, while the circuit between the contacts and the bank itself can also break, which leads to its complete failure. To revive such a dead man, the so-called frog (toad) is used. However, it is not always possible to start an over-discharged battery, so after that you can only throw it away. To prevent the battery from going into deep discharge, not only the charge controller on the battery is used, but also on the smartphone board. So it is impossible to bring a modern battery to a deep discharge during normal use, because two systems monitor this at once. Remember that even when the smartphone reaches 0% charge, in fact, the voltage on the battery remains around 3.3 V, which is clearly higher than the critical 2.8 V. Therefore, there is nothing to worry about if the device sits at 0%, but only if the device is immediately put on charge. Moreover, every 6 months you even need to discharge your smartphone to 0% to calibrate the battery. Remember that it is strictly forbidden to leave a completely discharged device without charging, since the battery will gradually self-discharge below 2.8 V, which threatens it with death. If you want to store your smartphone in the off state, then you should charge it to at least 60%, then turn it off and store it at a temperature between 15-20 degrees Celsius.

Overheat- at elevated temperatures, the batteries degrade very much, as the processes inside the cans intensify, which leads to swelling or even fire.

hypothermia- in the cold, Li-Ion or Li-Pol batteries lose capacity due to the fact that chemical processes inside them slow down very much, due to which the voltage drops and the smartphone turns off. Naturally, constant hypothermia of the battery does not promise anything good.

Therefore, it is worth remembering just two simple rules:

• Do not leave the smartphone for a long time in the heat or direct sunlight, as well as in the cold for a long time.
• Charge your smartphone only at positive temperatures, ideally at room temperature from 20 to 25 degrees Celsius.

Battery charge/discharge cycles

Upon reaching 500 full charge/discharge cycles, the battery capacity drops by 20% (at nominal temperature and charge current). If the operating conditions are not met, then the number of charge / discharge cycles is reduced by 2 times. At the same time, if the smartphone is not fully charged and discharged, the number of charge / discharge cycles will increase several times. However, this approach is also negative, but from the point of view of usability, since you have to constantly monitor the battery, put it on charge in time, sacrificing battery life.

but best solution nevertheless, there is an option when the battery does not reach critically low or high charge values. In this regard, the minimum charge should be at least 10%, and the maximum 90% - so the autonomy does not suffer, and the battery life increases. At the same time, more frequent incomplete charge/discharge cycles lead to micro-memory effects, after which they add up. Also, each charge, albeit slightly, but still heats up the battery, and high temperatures, as we already know, are harmful. That is why fast charging is not always effective, unless it is illiterately implemented.

Battery aging

The aging of a Li-Ion or Li-Pol battery is that, over time, the internal resistance and discharge currents increase, due to which there is a loss of capacity. Battery aging occurs on its own, but factors such as overcharging/redischarging, overheating and hypothermia, high charge/discharge currents, and the number of discharge/discharge cycles increase its speed. When the battery is used for two years, the capacity drops by about 4%, after which each subsequent year takes away 10% with it. Roughly speaking, a conventional battery will completely fail after 10 years, and this figure is rather big, since users usually change gadgets at least 1 time in 3 years. That is, when buying a new smartphone, you don’t have to worry about battery aging, but when purchasing a used phone, there is a risk of running into trouble. If a used smartphone is more than or about two years old, then it is best to refuse to buy, since the battery itself has aged during this time, and it is not known how correctly its owner exploited it.

How to properly charge a brand new smartphone?

The first days of battery life in a new smartphone are especially important, it's worth remembering. As far as we know, almost all manufacturers ship their smartphones with about 50% charged batteries. In this case, the battery must be discharged to zero calmly and without high loads (games, heavy applications), and even turning off the device does not carry anything terrible. After that, you need to charge the battery of your device to 100%, but again, without loads. In general, try to forget about games when charging your smartphone, as in this case there is a strong heating that provokes battery degradation. Complete charge / discharge cycles must be carried out at least 3. What is it for? In the production of Li-Ion or Li-Pol batteries, an inhibitor is used, which is added to the electrolyte. The inhibitor is designed to increase the storage life of the battery, so the first three cycles of full charge / discharge destroy the existing preservative, so to speak, and the maximum capacity is reached. The process of resolving an inhibitor is called depreservation - it has nothing to do with the memory effect inherent in nickel-metal hydride batteries.

If you immediately load the smartphone out of the box, then subsequently the battery will immediately lose some of its capacity, and the service life of the power element will decrease. Therefore, the process of destroying the inhibitor (re-preservation) is very important, and after that you can use the smartphone as you like, but taking into account everything that we wrote in this article. Then your smartphone and its battery will serve you for a very long time and the question of replacing the battery after some time of operation will disappear by itself.

Correct for its durability, you need to clarify the situation with batteries. It's all about their looks. Previously, the portable was equipped with nickel-iron, nickel-metal hydride batteries, but now laptops and smartphones have lithium-ion batteries.

Nickel batteries have a so-called "memory effect". The essence of this phenomenon is as follows: if you charge a battery that is 30% full, then the remaining 70% is remembered by the device as a “full charge”, while it is clear that the initial capacity is reduced. That is why the principle of charging a nickel battery has become widely known. Chemical changes recharging a full battery will result in capacity loss in the future.

The modern portable is equipped with lithium-ion batteries, which do not require full recharging.

How to charge your smartphone correctly

The device requires regular recharging. Do not allow the smartphone to be discharged to the end, to 0%. Even discharging the battery to 50% is not good option. When lowering the charge by 10-20%, it is already required to put the device on recharging.

The device must not be left on. Modern lithium-ion devices do not require constant 100% recharging. The best option recharging - from 40 to 80%. Try to stay within those limits. If the battery is 100% full, then it should not be left on charge, it is precisely such actions that lead to a reduction in the life of electronic devices.

How to charge a smartphone if this process occurs at night

In order for lithium-ion batteries to last for years, to maximize their lifespan, it is best to purchase energy-saving sockets. When the device is charged overnight, special sockets automatically turn off the charger after a specified amount of time.

If the phone is or is not of Chinese origin, then it already has a charge controller, which, upon reaching 100%, will turn off the charging itself, and in some cases even report a full charge with an audible signal. Naturally, such normal devices can be left online for a long time.

How to charge your smartphone to extend its lifespan

Once a month, but not more often, you should completely discharge the electronics, and then charge it to 100%. These steps are required to calibrate the device. The fact is that charge devices are in minutes or percentages, these functions can go astray with frequent small recharging, and therefore they should be adjusted monthly in this way.

It is unacceptable to allow the device to overheat, this will significantly reduce its service life. For this reason, you should not work with your laptop on your lap.

Modern batteries for mobile devices are different better reliability and performance, so many of their problems, which everyone knows about, have ceased to be relevant. Today we will renew your knowledge in this area so that you know how to properly charge your Samsung smartphone galaxy.

There is no instruction as it is not needed. First, do not bother with how and when to charge the battery. Just plug your phone or tablet into the power adapter and that's it. The only thing you need to know is that you should not cover the gadget so that it does not overheat. Excessive heat adversely affects battery life.

Secondly, do not use a non-original charger. Beware of cheap adapters from unknown manufacturers. You can use high-quality chargers from reputable brands that claim to be compatible with your mobile gadget model. If the smartphone supports fast charging, then the charger should also have this function.

There is no longer a need to discharge and fully charge three times in a row after buying a brand new device. Modern self-contained power supplies are devoid of the “memory effect”, so this recommendation is no longer relevant.

By charging the phone every time from 0% to 100%, its battery will last a maximum of 500 cycles and then lose most of its capacity. So what can you do to increase battery life? Here are some tips:

• Recharge your phone regularly. Don't let your phone run out of battery until you turn it off, and don't charge it to 100% for long periods of time.
• Keep the charge in the range of 10-80% and you can extend the battery life by at least 2 times.
• Don't leave your phone on charge all night. It only overloads the battery once again.
• Do not overheat the battery.

Of course, you should not dwell on all this. Don't worry if your phone runs out of battery and you can't charge it for a while, or you've fully charged it on a long trip. Even without our recommendations, the autonomous power supply of a mobile device will still serve you for several years.

Is fast charging bad for a Samsung smartphone?

The first versions of fast charging technologies really had a negative impact on battery capacity due to the fact that the phone got quite hot during the process. Modern designs are much more efficient than before, allowing for faster charging and less heat.

The drop in battery power is now so slight that after a few years of use you won't even notice a change. So do not be afraid that a few months after using the battery, the smartphone will become unusable.

Of course, if you still don't trust these technologies, then disable fast charging if you're not in a hurry. Many smartphone manufacturers, fortunately, allow this. If you cannot disable fast charging in your device, then use a quality power adapter that does not support fast charging. The phone will charge more slowly, but more confidently.

How to properly charge a new smartphone battery?

Many “specialists” will advise that a new battery needs to be charged with the device turned off for about a day, while others argue that without three full cycles charging and discharging is indispensable. I hasten to inform you that these tips are not suitable for modern Li-Ion batteries, as they are devoid of the “memory effect” and other shortcomings.

So what to do with a new battery, you ask? Everything is simple - practically nothing! We changed the source of autonomous power supply to a new one, charged it to 100% and use it. Do not discharge the phone to zero, there is no need for this. Over time, the phone will “get used” to it and will start working at full capacity, as well as display the correct charge level.

Follow the above tips and your battery will last much longer this time around. All recommendations also apply to new mobile devices whose batteries are in brand new condition.

Can I use wireless charging?

This method of recharging the battery can also overheat the phone, which reduces its life. If you notice that wireless charging is the reason why the device is always warm, then try to avoid using it.

Modern induction coils tend to heat up, there is nothing strange in this.

Drawing conclusions

If you want to extend the battery life of your smartphone or tablet, then these tips and tricks will definitely help you, but if you don’t want to bother, then it will still work for at least 2-3 years without problems.

Beware first of all high temperature heating of a mobile gadget, as modern lithium-ion batteries are very sensitive to overheating.

How to properly charge a smartphone with a new battery

The problem of any smartphone is its short battery life. Ordinary phones, the forerunners of smartphones, worked without recharging for several days. The battery of modern gadgets runs out in a day, a maximum of two. This is a fee for large screens, multimedia applications, Internet access, etc. Therefore, you have to charge the battery very often, which is why it begins to degrade a year after use. And to prolong the life of your smartphone battery, it is important to properly charge it while it is new. There is a lot of discussion about how to properly charge a new smartphone battery. Let's try to figure out this issue.

To begin with, it is worth saying a few words about the types of batteries used in phones. Modern smartphones use lithium-ion (Li─Ion) and lithium-polymer (Li─Pol) batteries. What are these devices?

Lithium-ion batteries have entered consumer electronics, displacing batteries as well. Lithium-ion batteries were superior in performance to the above except for the discharge current. Their value is much lower. But since this is not so important in smartphones, tablets and laptops, lithium batteries have firmly occupied this niche.

In lithium batteries, the main problem was the use of lithium electrodes. Due to the instability of lithium, it has not been possible to create a safe source of energy for consumer devices. Therefore, manufacturers began to develop electrodes not from lithium, but from its various compounds. And with a slight loss in energy density, they managed to achieve the creation of batteries with the required characteristics.

We recommend that you additionally read the article about the battery.
This is how lithium-ion batteries with a negative electrode made of carbon materials were developed. Cobalt oxides began to be used as the active mass of the positive electrode. This material has a potential of 4 volts with respect to a carbon electrode in which lithium is intercalated. Therefore, most lithium-ion batteries have a voltage of 3-4 volts.

During the discharge of a lithium-ion battery at the negative electrode, Li is deintercalated from the carbon material. Lithium intercalates into oxide at the positive electrode. When the battery is being charged, these processes go into reverse side. There is no metallic Li in the system. The charge-discharge process is the transfer of Li ions between the electrodes. They even began to be called accumulators of the "rocking chair" type.

Smartphones also use lithium-polymer batteries (Li─Pol). They are based on the transition of polymers to a semiconductor. This occurs when electrolyte ions are introduced into their structure. As a result of this process, the conductivity polymer material increases significantly. Scientists are working towards finding a polymer material that would replace the liquid electrolyte. Such searches are being carried out both for Li-Ion batteries and for batteries with metallic Li. In the latter, in the case of using a polymer electrolyte, the energy density can increase several times compared to lithium ion ones.

Now battery manufacturers have already mastered the serial production of lithium batteries of the following types:

• polymer electrolytes in which lithium salts are embedded. It may not be one polymer, but a mixture;
• dry electrolytes based on polymer. For the most part, this is polyethylene oxide with various lithium salts;
• microporous matrices, where non-aqueous solutions of lithium salts are embedded.

Smartphone battery charger

Now, as for the charger (charger) for the smartphone battery. Let's briefly consider the main aspects of choosing a memory for a smartphone:

• original or universal charger. It is better to charge the smartphone from the "native" memory. But if you choose a universal charger in accordance with the characteristics of the smartphone battery, then there is no difference. It is safe to charge from a computer, but for a long time;
• what current to charge. The charger should charge with a current not exceeding the maximum battery charging current. This value can be found in the characteristics of the battery. In most cases, with a smartphone battery capacity of up to 1800 mAh, the charging current is 1 A. If the capacity is larger, then 2 A;
• cable. Use the data cable to charge. The battery of the smartphone identifies the charger by it. Otherwise, the charging process may end sadly.

The new battery should be discharged to zero, namely before turning off the smartphone. After that, put it on charge from a standard network charger. Check your phone's manual for how long it takes to fully charge the battery. When charging a new smartphone battery for the first time, add a couple more hours by this time. In the case of charging with an original charger, you can not be afraid to recharge the battery. Such chargers turn off the current supply when a new battery is filled with capacity. After fully charging your new smartphone, you use it as usual.

It is not necessary to try to discharge as quickly as possible. The main thing do not forget that a new smartphone will need to be charged only after the battery is discharged to zero. And so the new battery will need to be charged and discharged 3-4 times. After that, the charge is already done in the normal mode.

With further operation, the new one no longer needs to be discharged to zero. Moreover, it is undesirable. It is necessary to put the battery to charge when the battery is discharged to a level of 12-14%. By the way, you don’t need to charge the smartphone’s battery to 100% if it is no longer new. It is enough to bring the charge level to 80-90%.

Experts recommend exercising your phone battery once a month. It consists in the fact that the battery is discharged to zero and charged to 100%. Do not forget the smartphone on charge for a long time if you use "non-native" chargers. This is fraught with battery failure. Be careful when using third-party chargers designed for car cigarette lighters. Choose such chargers according to the characteristics of the battery of your new smartphone.

There are devices that are popularly called "frogs" for their appearance. With their help, you can charge the battery directly without a smartphone. Their choice also needs to be approached carefully. The requirements are the same, matching the rechargeable smartphone battery in terms of power, voltage, current.
