How to charge a new phone. Smartphone battery: how to charge it correctly for the first time? How to properly charge a new phone with a lithium-ion battery

Majority Owners modern smartphones not happy with the opening hours electronic device without recharging, so many people think about optimizing its operation. It is equally important to put the gadget into operation correctly so that the battery subsequently works longer and more efficiently. To do this, it will be useful to learn how to charge a new battery on a smartphone so that after that it retains its original capacity for a long time. Practical advice will help you achieve the desired result.

Charging the battery after purchasing a smartphone

For normal further use of the battery, it must be charged in a certain way the first few times.

First, you need to wait until the smartphone is completely discharged and turns off. Then you need to immediately connect it to the mains using your original charger and start it up. Add 2 hours to the recommended charging time listed in the user manual. Modern chargers are capable of turning off the power after the battery reaches the required capacity, but it is better not to rely on this, but to disconnect it from the outlet yourself. After this, you can start using the gadget normally.

This procedure will need to be repeated with the battery 2-3 more times.

Further use of the smartphone battery

After several repetitions, bringing the battery level from 0 to 100%, you will be able to use the device in the most convenient mode. Experts recommend keeping the battery charge level at approximately 10-90% to increase the number of available discharge cycles.

It is important to remember that long-term storage mobile device with a completely empty (0%) or full (100%) battery is undesirable.

Monthly prevention

It consists of repeating the procedure performed immediately after purchasing the gadget approximately once a month, which includes completely discharging and filling the battery to 100%. In this case, one repetition is enough.

Charging device

It is recommended to use only original models, especially when leaving the smartphone unattended for a long time. In this case, there is a high probability of overcharging the battery. Particular care must be taken when choosing chargers that receive power from the car cigarette lighter so that they are ideally suited to the characteristics of a particular battery.

By following the described requirements, the smartphone user will be able to make the operation of the new battery trouble-free and as efficient as possible.

Properly charging your mobile phone battery can extend its life, which is especially important for models with a non-removable battery.

How to properly charge a battery is not an interesting topic for many until a smartphone or tablet faces the problem of ineffective operation.

Many of us have had the problem of running out of battery while away from home and unable to charge it, but few try to use a method to prolong the life of this key element.

The battery has been designed in such a way that after 500 full charge cycles, 80% of its original capacity is retained.

Once this point is reached, your smartphone's battery (for most manufacturers, after 300-500 cycles) will noticeably lose efficiency.

One of the most frequently asked questions is whether it is necessary to wait for complete discharge and about the memory effect.

Memory effect in phone battery

If you charge the battery too often, this can occur in the so-called “memory effect”.

If you charge a battery that has another 20% of resources to a level of 80%, then it can “forget” about 40%.

This sounds strange, but fortunately only applies to older nickel-based batteries (nickel-cadmium and nickel-metal hydride batteries to a lesser extent).

Lithium ion (li ion) does not suffer from memory effect. In their case, you should do the opposite - charge often, but not all day, and don't let it drain to zero.

NOTE: Do not charge the lithium battery from 0 to 100%. If a lithium-ion battery is systematically discharged to 0 and then charged to 100 percent, its service life is reduced.

It will be very good if you charge the lithium-ion battery in the range of 20% - 80%. Try to keep the resource without dropping below 20%.

Some of the smartphones and tablets currently available are capable of recognizing when the battery has finished charging and turning it off on its own.

However, experts recommend disconnecting your smartphone or tablet from the power source if this is done for a long time, since there is a risk of overheating, which Li ion batteries strongly dislike.

How to properly charge a new lithium battery for the first time

A new battery should always be discharged to zero for the first time - until the smartphone turns off. After this, using the original charger, not only charge the battery completely, but also keep it connected for another 2-3 hours.


After fully charging the new smartphone battery, you use it as usual, for the first time; it is not necessary to discharge it as quickly as possible, as was previously recommended in the old ones.

The main thing is to do a full charge the first time, after a complete discharge, and so on with a new battery 3-4 times. After this, go to normal mode.

How to properly charge your phone battery with a frog

There are universal devices - “frogs”. They are designed for lithium Li Ion batteries.

Charging is controlled by the phone's microchip and is automatically turned off if it is no longer needed, but the frogs do not support this, they differ from each other and not all are of good quality.

If you find 3 or 4 contacts on the battery, then the outer 2 are usually used. If the first green indicator lights up, then you did it right.

If it is not lit, change the polarity (CO button - polarity reversal). There are frogs that determine polarity on their own.

NOTE: The frog does not have charge control, so it is not highly recommended and is considered inferior to the original device.

Is it possible to use the battery fast charging system?

Many smartphones have a feature that allows you to quickly charge the battery (for example, in the case of technology, Motorola Turbo Charger charges in 15 minutes).

This solution is based on a special code that is powered at a higher voltage. Unfortunately, this is accompanied by a heating process, which is not a positive phenomenon in the case of a lithium-ion battery.

For the same reason, try not to leave your smartphone in the sun, because in the long run, high temperatures will shorten the battery life (its power will be significantly reduced).

Remember also that very cold conditions are also not favorable. Conclusion: it is better not to use the fast battery charging system.

Can I use any charger?

Use Charger, supplied with your smartphone or tablet, because then you can be sure that everything is correct. Cheap alternatives, unfortunately, can pose a threat to your phone.

Do not store the battery for too long on a zero charge. Leave her resources at 40-50%. remember, that unused battery discharges within a month by 5-10%.

If you leave a dead battery for a very long time, it may be the end - it will no longer be able to charge.


Of course, it is unlikely that for such a long period, you will not be using a smartphone, tablet or laptop. This applies primarily to the spare battery. Charging batteries correctly can greatly impact their lifespan.

The process of charging a lithium-ion battery is quite complex, and cheap chargers do not take into account the characteristics of the battery.

Smartphones discharge quickly, and their charging is slow and ask for much more often than older ones Cell phones. Good luck.

Over the past twenty years, smartphones have become an integral part of life. If people used to get along quite well without a phone, today, if you forget it at home, you feel like you have no hands. The main problem of many devices remains short battery life. Sometimes this is a consequence of poor quality, but more often the reason is improper operation. The battery will live longer if you know the charging rules. Let's figure out how to properly charge your phone.

How to properly charge the battery?

The recharging process is simple - you insert the charger cord into the phone connector and wait from one to three hours. But the catch is that it is during charging that people, without knowing it, damage the smartphone’s battery. What to consider so as not to buy new battery every three months?

Keep it regular

Don't wait for the phone to die. Frequently discharging to zero reduces the overall capacity of a lithium-ion battery. It is better to regularly charge your smartphone when there is 10–20% charge left.

There is a direct relationship between the battery life and the percentage of energy that remained in it at the time of recharging. Pay attention to the table below. It shows that the ideal solution is to recharge the phone as soon as the charge drops below 90%, but in practice no one does this.

Disconnect the charger promptly

This applies to cheap Chinese chargers and some original ones. It’s difficult to know which one stops supplying power after reaching 100%, so it’s better to play it safe.

Continuing to charge an already charged battery means gradually killing it. To avoid this, unplug the cord immediately or use special outlets that stop supplying power after a specified time.

Completely discharge and charge the battery once a month

This is necessary to calibrate the charge level indicators. The fact is that if you frequently charge your phone battery, the sensor will eventually display incorrect information on the screen. Therefore, a smartphone that just showed 70% charge may suddenly die.

Don't overheat the battery

Don't put your phone under straight lines Sun rays. High temperatures reduce battery capacity. At an average storage temperature of +25 degrees and correct conditions of use, the battery will lose 4% of its capacity in a year.

If a smartphone is frequently overheated above 60 degrees, its battery capacity will decrease by 25% over 12 months.

How to charge your phone without charging?

You often encounter a problem: an important call is about to take place, you are in the city center, and your smartphone has 5% charge left. What to do in such a situation if you don’t have a phone charger at hand?

Ask for help

Go to a large supermarket and do some shopping. Some of them have special lockers with chargers for customers. Put your phone on charge and walk between the rows for 10–15 minutes. The resulting energy should be enough for a 20-minute conversation.

Another way to revive your battery is to contact your carrier's office. They shouldn't refuse. And if they do take a fee, it will be a small one.

Use special terminals

Battery charging terminals are appearing in some supermarkets, waiting rooms and train stations. Unfortunately, there are still not as many of them as we would like. But it's worth looking. You will have to pay a certain amount for an hour of charging.

A laptop will help

The phone can be charged via a laptop by connecting it via a USB port. A data cable will do for this. Such charging will require more time, but, as they say, for lack of fish and cancer, fish.

What to do in a critical situation?

When there is neither a charger nor special terminals, you need to go to extreme measures. It's not certain that it will work, but it's worth a try. Remove the battery and place it on a metal surface in direct sunlight, such as a can.

Heating will speed up the movement of molecules, causing the charge to increase slightly. Half an hour of sunbathing for the battery is equivalent to about five minutes of much-needed communication. However, you should understand that this trick is harmful to the battery, and, of course, the procedure cannot be repeated several times.

Battery saving tips

If you see that your phone has 30% of the energy left and you won’t get home soon, turn off unnecessary functions and programs on your smartphone. The Wi-Fi, Bluetooth and GPS communication modules consume more power than others. Put your device in Airplane (or In-flight) mode and lower the screen brightness.

Staying connected is extremely important in modern world. A phone battery that runs out at the wrong time can seriously ruin your mood. To make this happen less often, follow the rules for using the battery and charge it correctly. new phone. How long does your smartphone battery last?

If I charge it to 100%, will this affect the battery life?

To answer these questions, we have collected all the information you need.

Many people have already become dependent on smartphones, so much so that some have even become nomophobes (nomophobia is the fear of being left without a smartphone).

Also, many people constantly worry that their phone might die at any time. However, few people think that battery life is also important.

Battery life

For the average user, a battery can last about 3-4 years, but this can be significantly increased if you follow some tips.

It is immediately worth noting that there are no eternal batteries yet. Most smartphone developers report that their devices are designed for 300-500 charging cycles.

According to Apple, iPhone batteries can reach 80% of their capacity after 1,000 charging cycles.

After this, phone batteries can no longer maintain a charge for a long time.

Here are some tips on how to properly charge your smartphone (iPhone or Android phone), tablet or laptop.

How to properly charge the battery

Many people wonder whether it is worth discharging the battery to zero before starting to charge it.

To answer this question, it’s worth learning more about the term “memory effect.”

What is the "memory effect"?



The batteries are able to remember how much charge is left (it only works when the device still has charge and has not been completely discharged).

If you frequently charge from 20% to 80%, then the battery may “forget” about the 40% that were not charged (from 0 to 20% and from 80 to 100%).

However, this applies to older nickel-metal hydride and nickel-cadmium batteries, but does not apply to lithium-ion (Li-ion) and lithium-polymer (Li-pol) batteries (we will talk about the latter below).

Li-ion and Li-pol batteries do not suffer from "memory loss", so they should be charged frequently, but not completely, and also do not allow them to discharge to zero.

How to properly charge your phone/tablet/laptop

Do not charge your battery from 0 to 100%



The rule for lithium batteries is that they should be kept at 50% or more at all times. When the charge drops below 50%, recharge it if possible. The best option is to charge the battery little by little several times a day.

But don't charge it to 100%. This, of course, will not be fatal to the battery, but regular charging to the maximum will significantly reduce the battery life.

It is worth noting that when discharging and charging by 50%, you can increase the battery life to 1,500 cycles.

Let's summarize: It is better to charge the battery from 40% to 80%, do not let the charge fall below 20% and rise to the maximum.

Correctly charging the battery

How often can you charge the battery to 100%?



Despite the fact that completely discharging a phone or laptop is not very good, there is still one exception. Lithium batteries(Li-ion and Li-pol) must be discharged to 0% at least once every 2 months.

This technique is similar to rebooting a computer, or a summer vacation for people. This action applies to both smartphones and laptops.

This training will help the device calibrate the electronics that are responsible for correctly displaying the charge level.

How to properly charge the battery

Should you charge your phone overnight?



Most modern smartphones are smart enough to stop charging when the battery is full, so there's little risk in leaving your phone charging overnight.

However, it is worth knowing that after a full charge, the battery of a phone, tablet or laptop will recharge the device from time to time so that the charge remains maximum. This action keeps the battery in a state of "stress", thereby gradually reducing its capacity.


If you leave your device charging overnight for a year, you will notice that your phone or laptop will drain faster than before.

How to properly charge a new phone or laptop


Now, with modern technology, there are no special instructions on how to charge a new phone or tablet. You just start using it, maintaining a charge between 40 and 80%

Previously, if you purchased new smartphone or a new battery for your phone, then it needed a “buildup”. This means that the battery had to be discharged to zero (until the phone/tablet/laptop turns off). They even advised discharging and charging the new battery to 100% 3-4 times. There is no need to do this now.

Lithium polymer battery


It is worth noting that the technology for creating lithium-ion batteries improves approximately 1-2 times a year. Therefore, it is becoming increasingly difficult to understand the behavior of new batteries after prolonged storage.

The lithium-ion battery has many advantages, but it still has some problems associated with operational safety, as well as high cost.

To solve these problems were created lithium polymer batteries(Li-pol), which appeared relatively recently.

More and more modern smartphones, laptops and tablets use this type of battery. In addition, such batteries can be found in modern radio-controlled toys.

What is the difference between Li-pol and Li-ion batteries?

Left Li- ion battery, right Li- pol battery

Lithium-ion batteries use liquid electrolyte, which is why problems arise when using them. Lithium polymer batteries work in much the same way, but have a different structure and a dry electrolyte instead of a liquid one. The dry electrolyte is a solid polymer and looks like a plastic film.

Today it is possible to create lithium-polymer batteries up to 1 mm thick, and also make them of any shape. It is also worth noting that the aluminum or steel case, which is used in Li-ion batteries, has been replaced with foil in Li-pol batteries.

How to charge lithium polymer (Li-pol) batteries


It is worth remembering that a lithium polymer battery must have certain voltage limits throughout its entire operating life. Most often it is from 2.7 (minimum charge) to 4.2 (maximum charge).

Such batteries The capacity is lower, but the service life is longer. Li-pol batteries do not like being completely discharged and charged to 100%. The borderline state for such batteries has a bad effect on their service life.

To maximize the service life of lithium polymer batteries, it is worth keeping the charge within 40% - 60% (in extreme cases, between 30 and 80%).

New Li-pol batteries When purchased, they have a charge level just within these limits.

Correctly charging your smartphone

Should you use fast charging?



Many Android phones have a fast charging function (this can be Qualcomm Quick Charge, or, in the case of Samsung phones- Adaptive Fast Charging).

These phones have special code, located on a chip also known as the Power Management IC (PMIC). This chip communicates with the charger and signals to it that a higher voltage is needed for a faster charge.

Fast charging heats up the battery, so you should also remove the case. Experts advise disabling the fast charging function if possible.

How to properly charge your phone battery

High and low temperatures harm the battery



* To avoid harm to your phone, tablet and laptop, do not leave the device in a closed car, near a stove or heater, or in direct sunlight.

*The same goes for cold temperatures, so don't leave your electronics in a cold room, and don't carry them in an outside jacket pocket in winter.

* A very useful thing for a laptop in the summer is a special stand that provides good ventilation for the device.

How to properly charge your smartphone or laptop battery

Can I use any charger?



If possible, use the charger that came with your phone. If you decide to purchase a charger from a third party, make sure that the manufacturer approves its use.

Cheap alternatives may harm your phone. There have already been cases of cheap chargers catching fire.


*Do not wait until the battery is completely discharged.

*Do not charge to 100%. After 80% you can safely disconnect from the adapter.

* If the battery is still discharged, immediately charge it.

* Ideally, the battery charge should be kept at 50%. This is difficult to do, so you can keep the charge between 30 and 80%.

* Frequent charging from a socket is harmfulLi-pol batteries. Try to charge from your laptop sometimes (just connect your phone to USB port). At the same time, it is better not to connect anything else to the laptop, otherwise there will not be enough current for charging.

* Li-pol batteries do not like prolonged exposure to high and low temperatures.

* Once every 2-3 months you need to completely discharge and charge the Li-pol battery, that is, to carry out calibration.

* When you decide to replace the lithium polymer battery, carefully look at its characteristics (voltage, connector, type, etc.) - they must completely match the characteristics of the battery being replaced.

* Lithium batteries do not have a “memory effect”, therefore, they do not need to be “overclocked”, that is, discharged and fully charged several times.

* Do not leave the battery discharged for too long. It is better to keep the battery charged at about 40-50%.

* Every month, batteries lose 5-10% of their capacity when completely discharged.

*If you leave a discharged battery for a long time, it will eventually fail to hold a charge.

* Spare batteries should also be charged at 40-50% and only then store for future use.

How to properly charge your phone? Whether it is new or old, whether its battery is worn out, branded (Samsung, Xiaomi, Apple) or Chinese “no-name” - in 2019, the rules for charging the battery for all mobile devices are the same from a scientific point of view.


Find out what is best for recharging your phone, tablet or any other modern portable gadget based on evidence and scientific claims.


How to extend battery life and service life?

The most common questions concern the features and rules for using a stand-alone mobile device. So, how can we extend the life of any battery, regardless of the type of battery used (Li-Ion, Li-Po, NiMH, NiCD)?

2. Deep discharge- remember that a partial discharge is safe, but a full discharge wears out the battery; it is optimal to keep the charge level from 30% to 80% (what is a deep discharge).

3. Hard work- choose phones that have a fairly powerful battery if you want to use your mobile device for games (like Pokemon Go) or resource-intensive tasks.



4. Fast charging- use only original chargers when your phone supports one of the proprietary technologies (Qualcomm Quick Charge, Pump Express, VOOC, Super mCharge and others). But if you want to extend the battery life, then in everyday use with high power adapters, try not to exceed the charge level of 80%.

5. Battery storage- the worst factors are elevated temperature and high voltage, therefore, it is optimal to place the phone or other gadget with a Li-Ion battery in a cool place partially charged (for example, up to 50%).


How to properly charge your phone and any other mobile device?

The instructions are the same for everyone modern gadgets that use a Li-Ion or Li-Polymer battery:
smartphones (iPhone, Android, Windows Phone, BlackBerry - on any platform);
phones (Java MID2.0, Symbian, Nokia, all kinds of Chinese dialers);
tablets (on Windows based, iOS, "Android");
GPS navigators, hand-held, portable, for cars;
smart watch (Xiaomi Mi Band, Android Wear, Apple Watch, Samsung Gear and so on);
laptops (from netbooks to ultrabooks and gaming PCs);
other autonomous high-tech products.

1. How to properly charge a new phone?

Simply plug in the charger and recharge before first and all subsequent uses. A full cycle or long charge is not required for Li-Ion and Li-Polymer - they are ready for use from the factory.


2. What bad things can happen to the battery?

Storing with a low charge level leads to the protection circuit being turned off and failure (the phone does not turn on, the percentage of the energy level “jumps”, and so on). Physical damage and external factors (especially heating) can lead to depressurization of the case and self-ignition of the battery (remember the story of the exploding Samsung Galaxy Note 7).

3. Does the phone need to be fully charged?

From a scientific point of view, partial charge of Li-Ion and Li-Polymer cells is more effective than full charge (up to 100%).


Maintain charge level between 30% and 80%.

4. Is it possible to interrupt battery charging?

Partially filling the battery capacity does not cause any harm - this is the most practical way to keep a smartphone or other mobile device offline.


5. Do I need to completely discharge my phone to the end?

Deep discharge (up to 0%, and sometimes even attempts to turn on a gadget with a discharged battery) leads to premature wear and aging.

6. Does the phone battery have a “memory effect”?

There is no “memory effect” in the batteries of phones, smartphones, tablets and laptops. Li-Ion and Li-Po technologies do not have the reversible loss of capacity without “training” cycles, like NiMH and NiCd batteries.

7. How to calibrate the battery in your phone?

If the charge percentage indicator begins to show erroneous data, then calibration will help correct the problem. The procedure can be repeated every 3 months with unnecessary functions turned off (switch to energy saving mode).

8. Should you unplug your phone when it is already charged?

Not necessarily - except that it is dangerous to leave another consumer in the outlet unattended. The battery expert community provides evidence that the phone's charging process is fully controlled and cuts off power from the charger when the battery capacity is already full.


9. Does a non-removable battery in smartphones last less than a removable one?

There is no difference - in both cases there is no need to remove the battery even during storage. It is enough to fill it at least halfway and put the device in the closet.

10. How can I safely store my phone and battery when I’m not using it?

To avoid damage to Li-Ion and Li-Polymer cells, the manufacturer requires that batteries be kept partially charged. But the temperature factor is even more important - it should be a cool place indoors.

11. Is it normal for the phone to get very hot while charging?

It also leads to overheating of the phone and battery (and its wear, see point 2). wireless charger with a coil and low-quality electronics - when purchasing, check the reviews for the words “heats up the phone.”

12. Can I charge my phone outdoors?

Yes - it is safe, provided that the air temperature is not lower than 0°C with relatively low humidity.

13. How to choose the right charger for your phone?

Check technical requirements to the voltage and current in the phone instructions. It’s very easy to find out whether a charger is of high quality or not - if the battery remains cold during the charging process, then everything is fine. If it gets hot, you should not use this charger.
