Most recent smartphones Apple, Sony, Samsung and other manufacturers produce monolithic gadgets without the possibility of replacing the battery.

It became a prerequisite for the correct charge of the phone, because now its service life directly depends on. To properly charge the smartphone or tablet, you need to follow simple, but efficient methods. There is a system of "three it is impossible", which will prevent the battery rapid wear and will provide its long work.

Fake charger

You can not use cheap fakes charger.

Despite the external similarity with the originals, their technical component is significantly different. Using such devices, you will not receive any guarantees. The foreign portal Lifehacker as part of the control purchases compared the quality of the adapters from the original manufacturers, third-party firms and cheap fakes. As a result, it turned out that only certified charging is coping with 100%. They are a little behind the charge of KMS and Belkin, and the work of fakes does not comply with the requirements and rules.

Be sure to get acquainted with our material about the Android smartphone.

Full of discharge

You can not allow full battery discharge.

This is one of the most controversial statements. In fact, everything is simple: specialists who prove the opposite, mean nickel-cadmium batteries of the last century. Due to their ineffectiveness, manufacturers moved to the installation of modern lithium-ion power sources. It is recommended to prevent, but if it happened, you can put the device for charging as soon as possible.

Warm places

It is impossible to charge the smartphone near the working radiators and in other hot places.

This thesis explains the nameplate below. It contains an approximate charge consumption depending on temperature. Not only the battery, but also the screen of the phone suffers from overheating.

At the end of the article, I want to give a few useful Soviets to extend the battery life:

• Once every 2-3 months, practice full discharge / battery charge. This will allow you to correct the correctness of the charge level on the device screen. Otherwise, the gadget can show unreliable figures in percent.
• If your gadget is discharged quickly, accept situations.
• Try not to leave your smartphone. It may adversely affect the operation of the battery, and rely on the automatic function of turning off the electricity supply to charger - a fairly risky step.
• To extend the life of the battery at least a couple of times a month, disconnect the device for the night. The complete lack of activity positively affects the battery.
• Be sure to familiarize yourself with our article about.

Compliance with these simple rules Provide a long and stable operation of the smartphone or tablet battery.

It is the opinion that after buying a new smartphone before charging, you must first completely discharge the battery. And this procedure must be repeated several times. In fact, over the past decade, a lot has changed and technologies are not at all those that were previously. Therefore, it is important to figure out whether you need to completely discharge a new battery.

Do I need to discharge a new smartphone battery

Now all the phones are completed or batteries. These batteries do not have a memory effect and they do not need a squabble in order to achieve maximum container. So purchased new smartphone It is not necessary, it can be immediately boldly to put it for charging and operate at its discretion.

New phones are no longer released with or batteries, but this does not mean that it is impossible to order a new battery for an old favorite phone. In this case, before operating, it is recommended to completely discharge it, since the Ni-MH and Ni-CD batteries have a memory effect and if this is not done, they may not go to the maximum container.

Do you need to fully discharge the battery before charging

In this case, everything is more complicated. Li-Ion and Li-Pol batteries have limited quantity discharge charge cycles. Approximately 500 full discharge cycles. Under these cycles is meant how many times can be discharged by a battery to 0% and then charge up to 100%.

All the difficulty lies in the fact that if the battery is charged at 10-20% and charge to the same 100%, the number of cycles increases to 1000. The total charge also does not reduce efficiency.

Ideally, Li-Ion and Li-Pol Akb must be charged at 20% and charge up to 80%. It will be the most sparing mode for the battery. It is almost impossible to track this, so you can install special application, for example Accubattery.

Nevertheless, once every 3 months it is worth producing a full charge cycle of the discharge.

With Ni-MH and Ni-CD batteries, everything is completely different. Whatever the capacity does not decrease better to completely discharge, and then fully charge.

Why did you need to discharge the batteries of phones

In the 2000s, many have only appeared mobile devices And they were far from light and not so flat as now. And all due to the design using Ni-Mh Akb. Features of such a battery consisted in the so-called "memory effect".

If you charge such ankb, for example, up to 90%, then it will remember this level and the next time you charge up to 100% it will fill the container only up to 90%, since the system will assume that it is already 100%.

Of course, if this is not systematic violations in charging rules, then nothing terrible will happen.

Therefore, users of such devices were important at first operation, be sure to completely discharge and charge the gadget. Old devices demanded a complete discharge cycle and charging.

Such manipulations need to be carried out if the need and the desire for the operation of the instruments for a long time occurs. The process of complete charge and discharge allows the device to always remember its maximum capacity.

There were questions or have it to add? Then write to us about it in the comments, it will make it makes the material more complete and accurate.

The topic entrusted with a large number of tips, recommendations, many of which, alas, have long been outdated and will rather harm the battery than the service life will increase.

So, we understand how you need to charge a new battery for the smartphone.

There are two leisure myth about the first charging.

Myth number 1. The new battery needs to be completely discharged for the first time, and then charge up to one hundred percent.

Some users prefer to discharge-charge the phone several times, believing that in a similar way you can "dig" the battery.

This delusion came from those times when nickel-metal-hydride batteries were stood in mobile communicators, which could not work on a complete capacity until several cycles of complete discharge-charge.

But for more than ten years almost all the phones (except is that unnamed Chinese fakes) work on lithium batteries.

Batteries of modern smartphones are:

lithium-ion;

lithium polymer.

Such batteries initially have a complete container and are not subject to the so-called "memory effect", that is, the battery will not remember, on which percentage of charge it was charged.

But! Manufacturers mobile phones Recommended in the first use once completely discharge and charge the smartphone. This is necessary to calibrate the charge controller and, as a result, the more optimal consumption of the battery capacity subsequently.

Myth number 2. Charge the battery for the first time you need 8-10-12 hours or more

Recommendations that a smartphone with a new battery must lie on charge from eight hours to days, do not work. In this case, more - does not mean better, because the power controller will still turn off the charge process as soon as the container reaches a hundred percent.

Thus, the long charging will not give the battery, except for a possible reloading. The recharge of the battery may occur if the temperature change will change: you charged the phone up to 100 percent of the house, went out on a hot street - the smartphone heated - a reload. And recharges negatively affect the battery. Therefore, the batteries for phones advise to charge to ninety-ninety-five percent.

Brief instruction how to charge the phone battery for the first time

1. Before use, discharge the battery to zero.
2. Then put charging until the charge level reaches 100%.
3. Remove with charging and use the smartphone as usual.

After the first charging, try not to allow a complete battery discharge and not to charge constantly to 100 percent, since the frequent recharge and reload reduce the available battery capacity.

The principle of working lithium-ion batteries is based on the movement of lithium ions between positively and negatively charged electrodes through the electrolyte. I would like this process to laugh forever, but everything in this world is susceptible to aging, and in the case of accumulators - degradation. If human life is measured for years and decades, the concept of the number of charging / discharge cycles is more suitable for the rating of the longevity of batteries. How to extend the life of your smartphone battery and what is a "sweet zone"? Explain.

The charging / discharge cycle does not have clearly defined boundaries, the depth of charging and discharge can vary, and the number of cycles can be reduced or increased depending on the intensity of the use and conditions in which the battery works. Therefore, to put the shelf life of such devices - the case is ungrateful. The resourceful user will always find the way to kill the battery before the term.

Since the release of the Sony Corporation, the first lithium-ion battery passed almost three decades. And if processors during this time every two years by the Moore law increased their power, doublening the number of transistors, then the batteries have increased by approximately 8% each year. The benefit of their production has been reduced by approximately the same dynamics. Today, lithium-ion batteries correspond to most expectations for the market of mass devices, let consumers and complain about the low capacity and the need for frequent charging. Believe it, it is the best that we have for mobile technology.

But tips on how with this "best" need to contact.

Leave a smartphone to charge for the night?

Yes. (However, in the long run, the effect of long night charging can be negative.) After a couple of hours by 100%, the battery stops accumulating electricity, and then the power controller dosage supplies energy into the battery, while holding its charge at the level of 100%. Unless, of course, it is necessary. Modern smartphones themselves are reluctant to the network at night, if they are right about it correctly. So not only the owner sleeps, but also the battery. And the power controller is following its safety, which will not be able to puncture the battery when he is already fed.

Do I need to discharge the battery to zero and charge up to 100%?

Do not. Most mobile devices are disconnected when the charge level reaches 3 volts to the cell. Or approximately 5% of the remaining actual battery capacity, let it in the system it will be already 0%. Manufacturers choose this threshold in order to leave the charge for maintenance of controllers, reduce the load on the battery, and also in case the phone is not immediately connected to z / y. To have a stock in case of passive self-discharge. This process may take months as long as the voltage decreases to 2.5 volts per cell. After that, the protective circuit will open, and the battery will begin fail.

In the industrial devices, this threshold of the residual charge may be higher, as there is a task to extend the service life of the instrument. Their batteries can operate in the so-called sweet zone (from 30 to 80% of the actual capacity), as this ensures the longest service life. In the consumer smartphone market, this is not being introduced, because we first are the question of comfort. Is it worth thinking about "sweet zones" if most people change their phones every 3-5 years?

Find a "sweet zone" on the chart

Tips to discharge the phone to zero remained since there were nickel-cadmium and nickel-metal hydride batteries in mass everyday. They possess the so-called memory effect - loss of capacity in the event that the battery has not been discharged completely, and the new charging cycle has already started. Lithium-ion batteries of such an effect are not experienced, they can be recharged at any time. Just decide for yourself with a "sweet zone" and comfort.

Why are lithium-ion batteries die still die?

Determine how much exactly the battery will live, quite difficult. But one thing can be said for sure - in the end she degrades. Why is this happening? This is due to an irreversible migration process of lithium ions, which are responsible for the transfer of an electrical charge between the electrodes.

When graphite (anode) enters into interaction with lithium and electrolyte, a film appears on its surface from the reaction products, which is called solid electrolyte interphase (Solid Electrolyte Interphase, SEI). Consisting of oxide and lithium carbonate film over time thickens and forms a barrier that prevents lithium ions to interact with the graphite anode and electrolyte. In addition, in the process of discharge, this lithium, which went to create a barrier, does not return to the cathode. This means that the battery gradually loses its effectiveness.

Ultra-quality charging harm the battery?

Ultricral charging apply only during the first phase of the smartphone charge. You already, probably, all the ears are shipped by these 50% in 20 minutes. So, this is due to the fact that the batteries are nonlinear devices. The most busy time for them occurs in the second half of the charging cycle, when the reception of lithium ions on the electrode is complicated. They seem to fight for recent parking spaces at the shopping center. In the second phase, the charge current decreases noticeably.

Experts remind that it is necessary to produce fast charging at a moderate temperature, because in the cold chemical reactions slow down. At the same time, overheating with quick charging can provoke a battery degradation attack.

Modern smartphones are equipped with power controllers that evaluate the state of the battery during charging, and also reduce or stop charging current if the battery turns out to be excessive voltage.

Disable Wi-Fi and Bluetooth prolongs the battery life?

The second energy consumption in mobile devices is the work of wireless interfaces. Especially indicative in this plan travel by train. The smartphone is constantly jumping from one base station to another, trying to catch a weakening signal of the cellular network.

If the train has a Wi-Fi-point, then it is better to connect to it. This can be saved not only mobile trafficBut also the battery charge, since the cellular receiver does not have to work overtime in a constant search for a stable connection.

As for Bluetooth connections, there are nuances here. In parallel with the improvement of mobile phones and an increase in the capacity of their batteries this technology wireless communication It became less energy efficient. In 2009, the Bluetooth Low Energy Specifications were adopted, which became part of the Bluetooth 4. BLE standard - this is part of Bluetooth, aimed at connecting to devices that are periodically exchanged by a small amount of data. That is, to play music in wireless headphones The smartphone will use Bluetooth Classic, for connecting with a fitness tracker - BLE. So it turns out much less considerable power. That is, limiting yourself in wireless interfaces seriously on autonomy will not affect.

If it is so important to extend the life of the battery in the last percent, it is better to turn off automatic brightness adjustment and set this indicator to the minimum level. The screen is the most important consumer of energy in the smartphone.

The smartphone battery can not be extinguished with water?

You can and need. The battery does not light up spontaneously. At least open flames precede overheating, hissing or bulge in the battery area. What do experts advise in this case? It is necessary to immediately remove flammable materials from the phone, and even better, it is gently to put it up to a non-combustible surface. At the same time, a simple shutdown of the battery from charging will no longer stop the destructive reaction inside the device.

But there is also good news. With a small lithium-ion fire, you can cope. First of all, with the help of a foam, carbon dioxide or powder fire extinguisher. But even the usual water will help to put out the clogged smartphone, despite the commodity network myths. Do not forget to de-energize the device.

The Federal Civil Aviation Office of the United States advises flight attendants in such cases to use water or gas bottles. A lithium-ion battery contains very little metallic lithium, which can join the reaction with water, highlight combustible hydrogen and thereby pour oil into the fire.

During combustion of the battery, carbon dioxide (CO2) is mainly isolated, a bit of fluoride hydrogen, phosphorus oxyfluoride and others are not the most useful for inhalation of the substance. So in the presence of smoke and gases, the room should be used. With proper use lithium-ion batteries Rarely occur.

That's right for its durability, you need to clarify the situation with the batteries. The whole thing is precisely in their views. Previously, portable was equipped with iron-leather, nickel-metal hydride batteries, now in laptops and smartphones lithium-ion batteries.

In nickel batteries, there is a so-called "memory effect". The essence of this phenomenon is as follows: if you charge the battery, filled with 30%, then the remaining 70% is remembered by the device as a "full charge", it is clear that the original container is reduced. It is precisely because the principle of charging a nickel battery became widely known. Chemical changes When recharging a full battery lead to a decrease in capacity in the future.

The modern portable is equipped with lithium-ion batteries that do not require complete recharging.

How to charge the smartphone correctly

The device requires regular recharging. Do not allow the smartphone to be discharged to the end to 0%. Even the battery discharge up to 50% is not a good option. When lowering charging, 10-20% is already required to put the device for recharging.

The device cannot be left on. Modern lithium-ionic devices are not required permanent 100% recharging. The optimal option for recharging is from 40 to 80%. Try to keep precisely in such borders. If the battery charged full program100%, it should not be left at charging, it is such actions that lead to a reduction in the service life of electronic devices.

How to charge a smartphone if this process occurs at night

In order for the service life of lithium-ion batteries for years to maximize their service life, it is best to get energy-saving outlets. When setting the device for charging for the night, special sockets through a given amount of time independently turn off the charger.

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

How to charge a smartphone to increase its service life

Once a month, but not more often, the electronics should be discharged completely, and then 100% charge it. These actions are required to calibrate the device. The fact is that the instruments show the balance of the charge in minutes or percentages, these functions can be knocked up with frequent small recharging, and therefore they should be adjusted monthly to this way.

It is unacceptable to overheat the device, it will significantly reduce its service life. For this reason, one should not work, holding a laptop on the knees.
