Charging a smartphone or tablet is a common procedure that users do every day without thinking. Meanwhile, if you charge the battery incorrectly, it quickly breaks down. In order to extend the life of the battery, certain rules must be followed.

Nickel-cadmium

The batteries that were used to equip the first phones back in the nineties. They were highly resistant to temperature extremes, withstanding cold down to -40 ° and heat up to + 60 °. The number of charging cycles was 2000. Batteries were not widely used due to the toxicity of cadmium and the "memory effect" that reduced the capacity.

The "memory effect" occurs when the battery is not fully charged / discharged. For example, if the user regularly charges the phone at 30%, the device “remembers” this figure as zero charge. Accordingly, 30% of the battery capacity is lost.

Nickel-cadmium batteries have a predominantly cylindrical shape

Nickel metal hydride

High-capacity batteries that do not contain toxic cadmium. They also have a "memory effect", large in size. Used in cheap older phones.

Nickel-metal hydride batteries continue to operate and are used in the manufacture of old-model cheap phones

Lithium ion

They replaced nickel-cadmium batteries and are used in modern smartphones and tablets. They are more susceptible to temperature extremes - it is not recommended to use lithium-ion batteries at -20 ° and below. Compact, capacious, having a plate or cylindrical shape. Advantages:

The lithium-ion battery is used in most modern smartphones

Lithium polymer

Modern polymer-based batteries. They can be of various shapes and sizes. Used in curved and flexible devices. The advantages of such batteries:

Disadvantages - danger of battery explosion, prolonged charging time of devices.

Flexible lithium polymer battery can take any shape

How to properly charge a new smartphone / tablet on Android

Modern smartphones and tablets are most often equipped with lithium-ion or lithium-polymer batteries.

Charging the smartphone in the off state is faster

There is a myth that a new phone / tablet needs to be charged overnight (6-8 hours), otherwise the battery life will be reduced. In fact, it is enough to charge the device to 100% for correct battery calibration.

The second myth is the need to disconnect the battery immediately after the device is fully charged, otherwise overcharging will shorten its service life. In fact, lithium-ion batteries have built-in microcircuits that automatically shut down the charger at 100 percent.

A new smartphone only needs to be charged in a special way if it has a NiMH battery. Such a battery should be fully charged and discharged three times to avoid the "memory effect".

Charging rules for devices that have already been used before

Users charge Android devices as the charge is consumed.

In the cold season, smartphones and tablets are discharged more intensively, and in hot weather they can overheat when charging.

General rules for charging the battery

The switched off phone does not consume power, so it charges faster.

Most modern Android models have micro-USB connectors for charging. Accordingly, a cable from a smartphone is suitable for a tablet, but the process will take place more slowly due to the reduced conductivity.

Battery Calibration

It happens that a smartphone or tablet starts to turn off at 20% and even at 50% charge. The reason is a software glitch, which can be resolved by calibrating the battery.

To calibrate:

Calibrate the battery once a month. For convenience, you can download the calibrator application from the Play Market.

Calibration can also be used to recover from a deep (heavy) discharge.

Battery Doctor app allows you to calibrate your battery

If you stop using your phone, remember: even a switched off device "eats up" the battery charge, and prolonged discharged state is harmful to it. Therefore, before turning off the device for a long time, charge the battery by about 60%, and then remove it and put it separately.

What connectors can be used to charge the tablet / phone

When a standard charging cable is not at hand, users wonder how else you can charge your smartphone / tablet. Can I use a USB port, headphone jack or HDMI output for this?

It is not possible to charge an Android device via the headphone jack. This technology is being developed by Apple.

Charging a smartphone using the headphone jack is a myth today. The only company developing in this direction is Apple.

Apple plans to use the principle of electromagnetic induction to charge gadgets. To charge the iPhone, it will be enough to install the plug from the headphones into the jack and place them on the contact device. An electromagnetic field will be created around it, affecting the battery charge level. However, the technology has not yet been tested.

USB port of a computer or laptop

The device for charging via USB can be made as an adapter without a wire

Devices can be charged not only from an outlet, but also from a computer or laptop. Complete with modern devices are USB cables for connecting to a PC.

Some laptops (Samsung, Toshiba) have a sleep-and-charge function that allows you to charge devices from USB, even when the computer is turned off.

For charging, it is enough to connect one end of the cable to the phone / tablet, and the other to the USB input of the computer.

HDMI input

HDMI is an interface that allows you to transfer high-quality graphic and audio information. It is not possible to charge a smartphone or tablet directly through this input. However, there are micro-USB to HDMI adapters that allow you to do this.

Car cigarette lighter

If the battery runs out, you can charge it from the car cigarette lighter

In the car, the smartphone / tablet is charged through the cigarette lighter socket.

When buying a car charger, pay attention to the plug and cable length. Use a car vacuum to remove dust from the cigarette lighter socket before charging your phone.

It is also possible to charge the device from a radio with a USB port. This is done by analogy with connecting to a PC.

Home appliances with USB port

You can charge your smartphone from any device with a USB output: TV, DVD player, router, audio system. Leaving the device on charging, remember that the current supplied to the USB is several times less than that on the computer. This means that the phone / tablet will take longer to charge.

External batteries

The external battery must have a larger capacity than the battery of your device

An external battery is a portable power source for a smartphone or tablet that allows you to charge devices in any conditions. Removable battery models differ in capacity, amperage and number of ports for connection.

When choosing a battery, focus on capacity. So, if the battery capacity of the smartphone is 3500 mAh, and the capacity of the charger is 2000 mAh, the charging will be incomplete, so you should choose a more powerful battery.

Disposable batteries

Manufacturers offer devices that allow you to charge your smartphone or tablet from AA batteries. The plug is connected to the device, and the batteries are installed in a special box - charging takes place, after which the batteries are discarded. The disadvantage of this method is its high cost, so it is suitable only for extreme cases.

Unusual adaptations

Other methods of charging devices are based on receiving energy and transferring it to the USB input:

Quick Charge technology

Powerbank with fast charging technology

Quick Charge technology was developed by Qualcomm. It allows you to charge tablets and smartphones faster by increasing the amount of current received from 5 to 12 V. To enable this function on Android:

To disable the function, uncheck the box in the device settings.

How to speed up smartphone charging

If you need to quickly charge your smartphone or tablet, use the recommendations below:

The battery is one of the most important parts of a tablet computer. And the correct operation of it depends on how long you can use the device during the day, and its service life in general. Especially considering that in many modern tablets, battery replacement is not provided at all by the design of the case. Is it possible to ruin the tablet battery by incorrect charging, and how to properly charge it in general, read on.

I think many people still remember how before, when buying a mobile phone, you had to "overclock" the battery with several full charge cycles, and how undesirable it was to recharge it with short charges during the day. Today, nickel batteries are a thing of the past, and most (if not all) mobile devices run on lithium batteries, but some, by inertia, continue to follow outdated instructions, although this is not only unnecessary, but sometimes even harmful. Well, let's skip the subtleties of the device of nickel and lithium batteries, and go directly to the main features of charging and operating the tablet battery. Adhere to the rules described below, and you can be sure that your battery will last a long time and trouble-free.

• There is no need to put your new tablet on multiple full charge cycles. Lithium batteries do not have a "memory effect", therefore, the benefit from such a procedure will be zero.
• Avoid draining your tablet when it turns off on its own. If this happens, put it on charge as soon as possible. Remember, full discharge will significantly reduce battery life.
• Try not to use the tablet in cold weather for a long time, this will reduce the battery life.
• Remember that short and incomplete recharging of the tablet does not harm the battery at all, so you can safely charge the tablet whenever possible or necessary (see note!).
• Do not use a fully charged tablet in extremely high temperatures. As battery capacity increases at high temperatures, you run the risk of “overcharging” it, which is harmful to lithium batteries.
• If you do not plan to use the tablet for a long time, charge the battery to 40% and turn off the device. At this level of charge, you can store the tablet for quite a long time without damaging the battery.
• And the last thing - do not be afraid to exhaust the battery life by frequent charging, lithium batteries lose their capacity over time, regardless of whether they are used or not.

How to charge your tablet from a computer

Tablets, like phones, have the unpleasant property of being discharged at the most crucial moment. If you often have such situations, try to carry a USB sync cable with you, most of the tablets can be charged from a computer or laptop via USB. However, do not forget that charging from a USB port takes much slower than from a charger. Also, keep in mind that if your tablet is too low or completely discharged, then the power from USB may not be enough and the battery will not be able to start charging.

And laptops have entered our life relatively recently, but along with mobile phones have firmly taken their place there. And now all mankind cannot imagine its life without computer technology and the Internet. People communicate on social networks, share information, find out the latest news, study and work through the Internet.

New development

Relatively recently, namely in 2010, a new device appeared on the computer market - a tablet computer, or just a tablet. It very quickly became widespread among users due to its compactness, as well as lower cost compared to laptops and stationary computers. It is very convenient to watch videos, listen to music, read books in electronic form, communicate on social networks on the tablet. But working on it, writing texts is difficult and inconvenient due to the lack of a keyboard and mouse. The advantage of a tablet is also lower power consumption compared to a laptop. But still it has to be charged. There are no problems when there is a charger nearby, and if it is absent, then the question arises of how to charge the tablet without charging?

How to charge?

You can use a USB cable. Well, every user of various gadgets probably knows how to charge a tablet via USB. It is enough to have this cable with the appropriate connector and a stationary computer at hand. It should be noted that charging a tablet via USB is much slower than through an outlet, since the voltage and maximum charging current in the computer are much lower. The tablet can also be charged in this way from a laptop. Charging from a laptop follows the same principle.

Charging rules

Previously, it was believed that for the device to work properly, it is necessary to completely discharge the battery before the first charge. Currently, tablets are equipped with a new type. And before using the tablet for the first time, you must fully charge it. In order for the tablet battery to last longer, it needs to be recharged more often and not to be completely discharged. The method described above for charging the tablet from a computer is also suitable for recharging the battery. But there are times when there is no USB cable either. And again the problem arises of how to charge the tablet without charging. In this case, you can use a cigarette lighter. This is where you need a car one. On the one hand, such a device has a connector adapted to the car's cigarette lighter, on the other - USB. You can buy it at any electronics store. Before charging in this way, first of all, make sure that it is sufficient. Then connect the cable to the tablet computer and to the car. This method is only suitable for recharging

Mister Samodelkin

There are a lot of tips on how to charge your tablet without charging. Some users offer the following option: in case there is no standard or car charger and there is no USB cable, you need to take any old charger that has been idle for a long time, and no one remembers which device it is intended for. Usually every owner of modern mobile phones has several of these at home. You need to cut off the connector for connecting to the phone - you won't need it, then strip the wires by removing the insulation from them. Two wires will appear - blue and red. Then you need to remove the battery from the tablet, find the plus and minus on it. Then connect the wires: the blue wire will go to plus, the red to minus, fix this structure with insulating tape or tape. Connect to an outlet, and that's it - charging is done. In this case, you need to act carefully so as not to get this method, although it is not very reliable in its design, but compared to how to charge the tablet via USB, it is faster, because the current in the outlet is more powerful and, therefore, the gadget will charge much faster. But this method is best used only in emergency cases. And in order to avoid such problems in the future at the most inopportune moment, it is better to purchase a spare battery and carry it with you.

A large number of options

There are chargers that allow you to charge your tablet computer from AA (finger-type) batteries via a USB cable. Radio amateurs can make such a device on their own, especially since everything you need can be purchased at a radio store.

If the "native" charger breaks down or is simply lost, and it is impossible to buy the same one, you need to purchase a similar one. There are several rules to follow when buying it. First, you should know such characteristics of current consumption as voltage and amperage. You can see them in the instructions or on the battery itself. Secondly, it is necessary to strictly observe the main rule - the voltage should not exceed 10 percent of the recommended indicator, and the current strength should be higher, but not more than 3-4 times. Otherwise, charging with a device that does not meet these requirements will damage the battery or the tablet itself.

How to extend the life of a tablet?

Some users believe that charging time depends on the operating system on which a particular tablet is running, but this is not at all the case. It all depends on the manufacturer of the gadget. So, for example, manufactures are the least capricious to the charging conditions, and therefore there are fewer problems with them when using various charging methods.

To prolong the life of the tablet battery, you must constantly monitor its charge level and do not allow it to completely discharge. It is not recommended to leave the tablet turned on during the process.

Thus, when answering the question of how to charge a tablet without charging, many answers arise. All presented methods are simple, affordable and safe, provided that simple rules are followed. But it is still recommended to use the charger that comes with the tablet and meets all its requirements. This will extend the battery life of the Tablet PC itself.

A good battery is nothing more than an element that is directly responsible for the battery life of your device. The type and capacity of the power source determines the amount of charge that you can consume while in autonomous mode. Currently, there are two types of batteries in use: lithium-ion and the newer and more advanced lithium-polymer. Therefore, from the very beginning of the acquisition, you need to know how much to charge the tablet for the first time, so that it works as long and stable as possible.

Charge indicator

The most technologically advanced batteries are lithium-polymer type. This technology has a number of features that in a short time brought this type of energy storage to a leading position:

1. The ratio of battery size to energy density is the most compact. That is, more energy can be accommodated per unit volume of the battery;
2. Lowest self-discharge and energy loss compared to other types;
3. The battery cell has high voltage as well as size. This allows you to make a device battery from one element (cell), which reduces its cost;
4. Low maintenance costs and long service life.

How much to charge a new tablet depends on technological innovations and the use of modern technologies. There are also small drawbacks that are eliminated by engineers who improve both the technology and the field of application:

1. Built-in protection circuitry. It is designed to control the charge of different cells and prevent overcharge / discharge;
2. Batteries cannot be stored for a long time, as the aging process takes place, which destroys the cathode in the cells.

How much do I need to charge new devices

The most common question among buyers who have just purchased a new device is: "How to properly charge a new tablet?" According to the technology of new batteries, you can charge your gadget as you like, if it does not contradict the rules of operation, although you need to pay attention to such a note as: "During the first full discharge, the minimum is set, and during the maximum charge, the maximum is determined." This means that in order to calibrate the power controller, you need to completely discharge the battery, and then charge your gadget at one time to the maximum value. By doing this, you will correctly set the initial default values, ensuring correct and correct power control.

The charging time of the gadget depends primarily on the rated current and voltage that the charging produces. If the power of the charged current is insufficient, you run the risk of charging failure and constant "undercharging" of the battery. Therefore, how much you need to charge the tablet will be determined by the charge controller, which will turn off battery charging when all capacities have the maximum value of the allowable charge current.

Based on statistics and averaged values, you can give an unambiguous answer to the question of how to charge a new tablet. As practice has shown, the time for a full charge occurs five to six hours after the connection of a completely discharged battery.

The quantity and quality of charging

The battery life and the period of its operation depends not only on the quality of workmanship, but also on the conditions of its operation. With the first, the buyer cannot do anything, but know how long it takes to charge the tablet and how it should. To reliably charge your gadget, you need to follow these rules:

1. Appropriate temperature conditions;
2. Allowable charging current and charging device used;
3. Reliable connection of wires and cables with your gadget.

Charging mobile gadgets can be carried out in different conditions, but it is worth considering some natural factors that are often overlooked:

1. What are you charging from (car charger and USB can supply a maximum of 500 mAh to all devices);
2. The voltage drop depends on the resistance of the charging cable (the longer the charging cable and the greater its resistance, the lower the voltage and current you will receive at the output of the connector);

In most cases, it depends on them how long it takes to charge the tablet.

Do not forget that a completely dead battery requires almost the entire potential of standard charging, since a large amount of energy is consumed to charge it, therefore non-native and low-power charging devices may not cope or even fail. So how much to charge the tablet? It depends on all of the above factors, which form the charging conditions, and they, in turn, and the time when your gadget is fully charged.

How to properly charge a gadget

In order for your device to work for a long time and stably, you need to know how to properly charge the tablet battery. To do this, you need to make the correct connection and comply with the charging requirements:

1. Make sure the network is operational and meets the technical requirements;
2. Determine the compatibility of the charger and charging (220V / 110V);
3. First connect the charger to the device (smartphone);
4. After that, connect the charger to the stationary network.

It is recommended to charge the gadget at one time, since it is in this case that the charge controller is least stressed. If, during charging, you actively manipulate the device, and even more expose it to strong resource loads, this will directly affect both the performance and premature failure of both the controller itself and an increase in the charging time of the gadget. So how long should you charge your tablet? It depends on the capacity of the battery, the controller on the battery itself and the power of the charging current.

How to properly charge the battery during subsequent use in order to maximize its life

Modern rechargeable batteries have practically no memory effect, that is, the charging and discharging graphs are almost identical. Despite this, batteries are subject to aging and wear and tear. There are two types of wear:

1. Natural;
2. Active use.

Natural wear and tear is the gradual oxidation of the cathode mainly, as a result of which part of the capacity and voltage of the cell is lost. This type of wear cannot be stopped. The average battery life is about two years, after which it can fail for natural reasons. Also, natural causes include overcharging or severe discharge of the battery. To prevent this, a power management circuit is installed. It is she who determines how much to charge the tablet.

Wear and tear from active use is determined by the number of charge and discharge cycles, as well as the condition of the battery cells themselves. After each time the charger is connected to the device, all battery cells undergo a fault tolerance and operability test, after which they begin to charge. The performance of each device depends on how the power plan works. Because of this, there is absolutely no difference how to properly charge an android tablet or with any other operating system.

To maximize the battery life, you need to periodically (no more than once a month) carry out preventive discharge and full charge in one step. These steps are intended to ensure that the power controller can continually calibrate as the battery capacity decreases over time. Therefore, how to properly charge a Samsung tablet should be known to every user of this brand, since this directly affects the operating time of the device not from a stationary network.

Refer to the user manual for the approximate standard time to fully charge a new device battery. From it you should also find out how much to charge a Samsung tablet from a standard charge. But despite this, over time, you can clearly see the deviations and roughly determine the degree of wear and tear on the battery of the tablet device. I hope our article was useful to you. You can find a lot of interesting and useful information on our website.

Currently, tablet PCs, as well as laptops, smartphones and mobile phones, usually use rechargeable batteries made on the basis of lithium and ions, that is, the so-called lithium-ion batteries. The question of the correct charging of such batteries is not at all unambiguous.

Dispelling Myths About Battery Charging

Some believe that the degree of their charge should be maintained within 40-80%, preventing a complete discharge, while others are sure that it is necessary to wait until the battery is completely discharged, and only then charge it to 100% capacity.

These different approaches are associated with previously widely used nickel batteries, which were characterized by a "memory effect". In fact, such batteries had to be discharged to zero, and then recharged, otherwise the battery would not "give out" all the energy. That is, the battery “remembered” that its capacity had not been fully used, and, at the next discharge, gave energy only up to the “remembered limit”. This does not apply to lithium-ion batteries, just the absence of a memory effect is their great advantage. Let's try to figure out how to properly charge such batteries.

How to charge the battery on the tablet

It must be remembered that you cannot bring the battery to full discharge, in the ideal case, you cannot allow more than 80% discharge. You need to charge the battery on time, then it can last several times longer than with improper use. Lithium - ion batteries work great even with an incomplete charge, for example, at a charge level of 50-80%, and vice versa, a full, 100% charge is even undesirable for them, as this shortens their service life. In turn, deep discharge can completely destroy the battery, which can entail costly repair of the tablet PC.

Remember that lithium-ion batteries age even when not in use. After 2 years of storage, the battery may lose about 20% of its capacity, that is, it makes no sense to buy such batteries "in reserve".

Calibrating the tablet battery

It is recommended to periodically, once a month, carry out a full discharge cycle and fully charge the tablet PC battery. Such cycles are needed to calibrate the battery cells. The fact is that on tablets and other similar devices, when batteries are operating in a mode with frequent and short charging cycles, the program that controls the state of charge of the battery malfunctions. After full discharge and full charge cycles, the program is "calibrated" and the tablet charging indicator starts working correctly.

Heating the tablet as a negative factor in battery performance

As you know, the battery is a chemical source of electrical energy, and at high temperatures all chemical processes are activated, therefore, to prevent the rapid discharge of the battery, try to store it in a cool place and protect it from heating.

Unfortunately, some tablet PCs get hot during operation, especially in "heavy" applications, such as toys. It's hard for me to judge how this affects the battery, but I hope the manufacturer of your tablet PC took this circumstance into account and protected the battery from overheating.

Keep in mind that the higher the temperature at which the battery is operated or stored, the shorter its service life. It is better to store lithium - ion batteries 40-50% charged, at a temperature of about 0-10 degrees.

Conclusion

In conclusion, I would like to say that if you use the above recommendations, then, of course, the battery life will be extended, however, you do not need to take these tips as dogma, for example, nothing terrible will happen if the battery is completely discharged, just try, so that it doesn't happen regularly. I would also like to note that the battery in a tablet PC can always be replaced.

Users of modern smartphones are accustomed to the fact that their devices are charged in a couple of hours from zero to 100%. And if we talk about smartphones with a fast charging function, they can be charged up to 50% in half an hour. When a tablet falls into the hands of such a user, the charging time of this device may surprise him greatly - much longer than two hours. And a very standard question arises - how much should the tablet be charged?

The answer to this question can be said only if you know the tablet model. Why? Primarily because the batteries of mobile devices vary greatly in capacity. So, there are tablets with a 3000 mAh battery, and there are those where the battery capacity exceeds 8000 mAh! Accordingly, in the first case, the tablet will charge much less, possibly several times.

Want some time? On average, charging from 0 to 100% in the case of tablets takes 2-3 hours and up to about 7-9 hours for devices with a very capacious battery (this also applies to new tablets). Will you say that it takes a very long time? Alas, these are the features. In fact, it would be possible to use fast charging for mobile devices, but this negatively affects the performance of the battery, so manufacturers are still carefully using the fast charging function, moreover, it allows you to charge the device to about the first 30-50%, after which it switches to normal charging mode - so as not to cause unnecessary harm to the battery.

So, gentlemen, if you have a tablet with a large-capacity battery, you shouldn't be surprised that a full charge cycle takes 5 hours or more. Of course, if the tablet charges, say, 15 hours instead of the usual 5 hours, this is clearly some kind of malfunction.

By the way, pay attention to the fact that the article is only about those cases when you charge the device from the outlet. If you charge it from the USB port of a computer, it is not surprising that the tablet takes all 10 or even 15 hours to charge. The fact is that the USB port limits the amperage, so charging in this case can be very stretched. Some tablets do not charge at all from the USB port of a computer or laptop.

What if the tablet takes a very long time to charge?

• Reload it.

• Change USB cable or charger.

• Only charge your tablet when plugged in.

• Clean your contacts.

• Reset your device.

• Contact the service center if all else fails.

Articles and Life Hacks

Many modern device owners do not know how to charge the tablet for the first time. With the purchase of this computer device, you will need to take into account some rules.

The user needs to be smart about the new battery that the gadget is equipped with.

Sequential instruction

1. Calibration of the power controller.
2. First, the battery installed on the device is completely discharged.
3. When charging for the first time, you need to make sure that the network is functioning correctly. It must meet the technical requirements.
4. It is important to determine the compatibility of your tablet and charger.
5. Then the charger is connected to the device, after which it can be connected to the network.
6. After that, the computer mobile device must be fully charged once, up to the maximum level. These actions will allow you to correctly determine all the standard initial values.

   At the same time, the user will ensure correct and competent control over the tablet power supply.

Some nuances

If the power level is insufficient, then the gadget may face a battery failure. It is equally important to know exactly how to charge the tablet for the first time in order to avoid systematic "undercharging" of the battery. This is why it is so important:

• The device should be charged exactly as much as the power controller determines. It is able to disconnect the charging of a computer device in a timely manner. In this case, the capacity will have an optimal level of permissible charge.
• As a rule, it is recommended to charge a new tablet for at least 5-6 hours for the first time.
• During this procedure, you will need to use only the "native" charging device, the desired temperature regime. It is equally important to check that the cables and wires are properly and securely connected to the computer device.
• It is recommended to stop using low-power and non-native chargers. They, as a rule, do not cope with the task at hand. This could damage the tablet battery.
• It is best to use a charger with small cable parameters. The longer it is with high resistance, the lower the voltage at the output, the connector will have.
