Right for its longevity, you need to clarify the situation with the batteries. The whole point lies precisely in their types. Previously, the portable was equipped with iron-nickel, nickel-metal hydride batteries, now in laptops and smartphones, 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 when recharging a full battery will lead to a decrease in capacity in the future.
The modern portable one is equipped with lithium-ion batteries, which do not require a full recharge.
How to charge your smartphone correctly
The device requires regular recharging. Do not let your smartphone run down to the end, to 0%. Even discharging the battery to 50% is not a good option. When the charge is lowered by 10-20%, it is already required to put the device on recharge.
The device cannot be left on. Modern lithium-ion devices do not require a continuous 100% charge. The best option recharging - from 40 to 80%. Try to stay within these boundaries. If the battery is fully charged, 100%, then it should not be left on charge, it is these actions that lead to a reduction in the service life of electronic devices.
How to charge a smartphone if this process occurs at night
For lithium-ion batteries to last for years, to maximize their lifespan, it is best to purchase energy-efficient outlets. When setting the device to charge at night, special sockets turn off on their own after a specified amount of time Charger.
If the phone or laptop is not of Chinese origin, then it already has a native charge controller, which, upon reaching 100%, will turn off the charging by itself, and in some cases even report full charging with a sound signal. Naturally, such normal devices can be left on the network for a long time.
How to charge your smartphone to extend its lifespan
Once a month, but not more often, you should discharge the electronics completely, and then charge it 100%. These steps are required to calibrate the device. The fact is that the devices show the remaining charge in minutes or percent, these functions can get lost with frequent small recharges, 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 the laptop on your lap.
How to properly charge a smartphone so that the battery lasts longer, I will tell you in this article. I usually change my gadgets once a year as it comes out. a new version... Therefore, if you do the same, this review will not be relevant for you. And if you have been using your phone or tablet for a year or more, it is better to follow the recommendations below. Simply put, so that your lithium-ion or lithium-polymer phone battery does not degrade faster than you decide to buy a new smartphone, you need to follow a few simple rules. There are slight differences for Li-Ion and Li-Po batteries, but this is a separate topic for conversation, there will be an article on this as well.
The first, but not a mandatory rule - take your smartphone off the charge, do not leave it on the network all night. After charging is complete, the device is only occasionally powered by current to maintain 100 percent. Due to the long charging time and elevated temperature, the battery is constantly under stress and after a year you may notice a noticeable decrease in the smartphone's battery life.
Second, do not completely discharge your smartphone. This means up to 5% and below. Modern mobile phones usually turn off automatically when the charge percentage drops below 5%, this is a kind of built-in protection. But in any case, such complete discharges wear out the battery a lot, despite the presence of power controllers. Only in the case when incorrect information about the battery capacity is displayed, can the device be discharged to 0 and charged to 100: for calibration.
Third, you can charge at any time convenient for you. With the advent of Li-Ion batteries, there was no need to wait for a full discharge or charge. Scientists from Battery University, who are researching this topic, advise charging gadgets from 40% to 80%, because when reaching 100%, the charger keeps the battery in a high voltage state, which wears out the structure of the battery.
Conclusion: the battery is much better if you charge it often and little by little than once and for a long time.
Fourth as a rule, use only branded chargers, especially if your smartphone supports one or another format fast charging... These power supplies usually (but not always) shut off the current completely when they reach 100%. If the bundled charger is out of order, or you came with a regular power supply unit without fast charging, try to find an original unit from the manufacturer for your smartphone, taking into account the type of fast charging (see voltage and amperage). Or you can order an analog from a good manufacturer on Ali. For example, I do just that, I use fast charging from UGreen, where two connectors are for the usual one, and one for the Quick Charge 4.0 standard. We also do not forget about the cables, because it must be designed for the required power. For example, I take 60W cables.
Do not forget about a cable that is suitable in terms of power.
Fifth, it is important to observe the temperature regime, because extreme heat or cold lead to a rapid discharge and disable the battery if you actively use it. For example, there is absolutely no need to charge a smartphone lying in the summer under the sun, for example, in a holder on the windshield of your car. This leads to rapid degradation of the battery, and in some cases, to the explosion of the battery. I will say even more, one time Apple I recommended removing protective covers from smartphones while charging, because this prevents heat from dissipating from the case. Given I do not use apple products, so I don’t know what is being written in the instructions in the boxes.
In the open spaces of the application store, both for Android and IOS, there are many applications that will monitor and advise you when to put or remove your smartphone from charging. I don't use it, but I have to say.
There you can also find all sorts of task managers that will help limit the activities of unwanted programs running in the background or disable their startup. Although, most likely, you may need root-rights.
Here are some applications for Android for working with the battery, you can read the descriptions on the application page:
- Accu Battery;
- Battery Calibration Pro 2018;
- Battery Monitor.
In modern smartphones with shells, manufacturers have already begun to build in scheduled charging options. For example, there is such a function when you can programmatically turn off the power, and not maintain 100% when the phone is fully charged. Also in the MIUI firmware from Xiaomi (and some others) there is a setting for the charging schedule by the hour.
And if you still own a smartphone with a removable battery and do not plan to use it for a long time, it is better to remove it and store it separately in a cool and dry place.
Modern smartphones are extremely active in consuming battery power when compared with conventional ones. push-button telephones... Why? The main source of power consumption is the screen - the larger it is, the higher its resolution, the higher the power consumption. And this is only the main source, and there are still a lot of additional ones. Accordingly, you usually have to charge your smartphone once a day or two days. How much should it charge?
You must understand that there is no exact answer to this question, since everything depends, firstly, on the model of the device that you are going to charge, and secondly, on the situation in which you have to charge the gadget. What does it mean? This means that depending on the charging method, the gadget can be charged at different times. So, if you use a branded charger and charge your smartphone from the mains, it can be charged, say, 3 hours when fully discharged to 100%. If this is done from the USB port of a computer, the indicated figure can be multiplied by 1.5-2, and this is because the USB technology produces only a certain current, which limits the charging speed of the device.
Generally speaking, a full charge of a smartphone from the network takes, on average, 1.5-3 hours. Accordingly, if a smartphone has a 1500 mAh battery, it will probably charge much faster than a smartphone with a 3000 mAh battery.
Want a more specific example? Let's take a multi-generational iPhone.
Here's what we got:
- iPhone 5SE, 6, 6S: 2 hours 10 minutes
- iPhone 6 Plus, 6S Plus: 3 hours 40 minutes
- iPhone 7: 2 hours 20 minutes
- iPhone 7 Plus: 3 hours 40 minutes
Above is the approximate average time charging iPhone from 0 to 100%, however, we remind you once again that these data are only approximate and may vary.

It would seem, what could be easier than putting your phone on charge ?! But on the Internet, the same questions appear over and over again regarding how to properly charge a smartphone.
The vast majority of modern phones have a non-removable battery. service center... And the prices for such a procedure are not very encouraging. It is for these reasons that users want to extend battery life as much as possible.
We have collected the most popular questions about charging a smartphone and in this material we would like to give comprehensive answers to them. So:
Question: How long is a smartphone battery designed for?
It is impossible to give a short answer to this question. Too many factors affect battery life (which we'll talk about later). For example, Apple officially declares that the iPhone battery is designed to retain 80% of its original capacity after 500 complete cycles recharge. We can say that 500 cycles is the average for any modern lithium-ion battery.
1 cycle- this is a full discharge of the smartphone, followed by charging up to 100%. According to Apple, if we discharged a fully charged smartphone to 50%, then charged it to 100% and the next day discharged it again to 50%, only then we get 1 recharge cycle (twice 50% each).
Roughly speaking, if 1 full recharge cycle occurs daily, then after 500 days(or almost a year and a half) the battery capacity of your smartphone will be 80% of the original.
Why then worry about charging at all, since the battery will last for at least a few years? The fact is that in reality, everything is not as great as on paper. If the battery is mishandled, you may well reduce the service life to 200 cycles (that is, after six months you may notice that the smartphone holds a charge worse).
And if you take into account the words Battery University(the most popular information resource on batteries and accumulators), then every time you connect your smartphone to a charger, when it is discharged to 70% and below, 1 recharge cycle occurs. In addition, Battery University states that a battery loses on average 15% to 22% of its original capacity over 1 year.
Question: Do I need to completely discharge it after buying a new smartphone?
Once you bought new smartphone, it will not be superfluous to carry out 1 full recharge cycle. That is, charge the smartphone to 100% and then discharge it until it turns off completely (don't worry, modern technology is smart enough to turn off the smartphone even before the battery is deeply discharged).
Why do you need to do this? Such a procedure does not make any difference to the battery and will not prolong its life in any way. A full recharge cycle needs to be done to calibrate the software so that the percentage of charge displayed by your smartphone matches the actual charge of its battery.
If you have never done the calibration procedures ( full charge up to 100% followed by discharge until the device is turned off), then your smartphone may incorrectly display the charge level and, for example, turn off with the remaining 10% charge.
Moreover, such a calibration can (and even should) be done every few months.
Question: Is it useful to discharge the phone "to zero" every time?
It is this usage scenario that is most harmful to a lithium-ion battery. Do not let the charge drop below 20% and recharge your phone more often. Otherwise, battery wear will accelerate. It is best to keep the charge between 40-80%. You will not harm the battery by charging it 2-3 times a day.
Once again, I would like to emphasize this idea - it is better to put your smartphone on charge more often than wait for it to be fully discharged.
Question: Can the phone be charged overnight?
This is one of the most popular questions about smartphone battery life. Indeed, many people find it convenient to put their phone on charge right before bed and get a fully charged phone in the morning.
The biggest danger in this case is battery overheating ( high temperature - enemy number 1 of any battery). Fortunately, overheating has nothing to do with prolonged charging. You theoretically won't be able to charge your smartphone overnight - smart electronics won't allow that. As soon as the battery receives required charge, it will be immediately disconnected from the network. It is for this reason that the phone is completely cold in the morning.
On the other hand, a fully charged battery is the most "stressful" for the battery, and keeping it at 100% overnight will shorten its lifespan.
If you plan to use your smartphone for a long period of time (say, 4 years or longer), then it is best not to leave your smartphone charging overnight. Otherwise, in 1-2 years you will lose all the same 20% of the capacity.
Question: Can I use my smartphone while charging?
There are two reasons why people are interested in this issue - personal safety and the impact of this factor on the battery.
As for the first reason - you don't have to worry, the smartphone will not shock you or explode in your hands. Yes, there are cases when this happened, but the reason for this was low-quality (very cheap) Chinese chargers and / or batteries. Therefore, it is worth using only original devices from well-known manufacturers.
If we talk about the battery itself, then it is very harmful for it high temperatures... During charging, any smartphone starts to heat up (by the way, if your smartphone gets very hot, you need to figure out why this is happening, it should not be so).
By using your smartphone while charging, you raise the temperature even more. Therefore, you cannot simultaneously charge your phone and perform "heavy" tasks on it (for example, play games). If you just want to charge your smartphone and listen to music, this will not harm either the battery or you.
Question: Is it harmful to charge the phone with a quick charge every time?
In fact, the smartphone is charging fast only up to half (when it is safe for the battery) - then the electric power decreases (due to a decrease in the current or voltage) and the phone continues to charge slowly. Failure to disable fast charging could result in battery swelling and rapid degradation.
Apparently, fast charging is an inevitable advance in technology. And in the near future, "slow" charging will simply disappear. Therefore, there is no point in avoiding fast charging.
Question: Can I use Chinese (non-native) chargers?
In no case! Always buy only original chargers, batteries and even cables. For example, using an original Samsung charger and battery along with a cheap Chinese USB cable, the company's smartphones with fast charging will charge slowly. That is, the cable will play a key role and will not allow you to use fast charging.
Moreover, there are many examples when cheap Chinese chargers melted right in the outlet, caused short circuits and even shocked a person. Non-original batteries may swell while charging and / or explode.
Also, chargers and cables from unnamed Chinese companies can damage the smartphone itself. The cheapest components are used in such devices, and the soldering and assembly does not hold up to scrutiny. All this leads to the fact that the real values of the current and voltage may not coincide with those declared by the manufacturer.
Most people still believe that a new smartphone, in particular its battery, should be immediately discharged to zero after purchase. And only then can the new battery be used to its fullest potential. Unfortunately, this is not the case at all.
The fact is that the modern cellular differs from prehistoric predecessors not only in the touch screen, the presence of the Internet and the built-in camera, but also in the battery.
Previously, mobile phones were equipped with iron-nickel batteries, which really had to be discharged immediately after purchase. This is due to the fact that this kind of batteries had the so-called "memory effect". The essence of the effect is very simple: when the battery was charged from 20%, the device took 80% for a full charge. In this way, because of the first unsuccessful charging you have already lost 1/5 of your potential energy reserve. Therefore, it is not surprising that buyers of brand new smartphones are worried about such an issue as the first charge.
But don't panic. Currently, in modern smartphones, iron-nickel batteries have been replaced by a lithium-ion battery (i-ion). Therefore, in modern realities, it is correct to ask not how much to charge a particular device, but how to do it correctly.
Modern smartphones, for example, Honor or iPhone, need more regular recharging, rather than charging the device for 1 times from 0 to 100%.
In no case should the smartphone be allowed to discharge to 0% - such actions lead to the fact that the device gradually begins to lose a potential amount of energy, which cannot be restored in the future.
That is why smartphones remind of a low battery charge already at 20% and repeat when 10% remains. Remember that if the reserve of your battery has reached such a low value, then it must be put on charge. The optimal battery charge is between 40% and 80%. Stick to it, and then your smartphone will live as long as possible.
Also, experts of the Battery University portal note that it is advisable to put the smartphone on recharge at 50% of the remaining energy. If you follow this nuance, then, according to research, battery life will increase by 4 times. If the smartphone has restored its power reserve to 100%, then it should not be left on charging, since the device's battery overheats, which also leads to a reduction in potential.
However, if you have such a lifestyle that your smartphone can be charged exclusively at night, then energy-saving sockets are sold especially for you in the modern market. Such a device has a built-in timer. Therefore, if you know that your gadget will reach its maximum charge in an hour and a half, set the time on the timer and rest calmly.
Also, high-quality original smartphones already have built-in charge controllers, which, when reaching 100%, independently turn off the flow of additional energy.
However, it is necessary to discharge the device periodically before turning it off, but not more often than once a month. This is due to the fact that, due to regular recharging, the sensors that track the remaining energy can get lost. It is because of this that your device can unexpectedly turn off at 10%. Therefore, once a month, do not be afraid to discharge the equipment before turning it off, and then charge it 100%, because in this way you will restore the correct operation of the sensors.
By the way, you can find out about the capabilities of your battery simply and free of charge thanks to the Battery Life app. It will show the number of charge cycles of your device, the wear and tear of the battery, and also indicate which specific applications require the most energy.
How to properly charge your Xiaomi phone
If you are thinking of purchasing a new and fashionable Xiaomi or have already acquired the ultimate Redmi 4x, then there is no point in worrying: charging such a device is much easier than discharging it, because the battery capacity of the latter is 4100 mAh.
However, if your Xiomi still loses ground and turns off at 20% charge, there is no need to panic - our instructions are universal and suitable for all types of modern smartphones. You just need to calibrate the charge sensors by discharging the phone to 0% and charging it to 100%.
If that doesn't work for you, then the problem is probably with the technical aspects of the device. In this case, do not be too lazy to refer to the instructions, paying attention to what it says about the duration of recharging. Leave the phone plugged in for the specified amount of time. After that, if the phone is 100% charged, you can unplug it from the outlet. Then follow the above rules. If the phone still continues to be capricious, then you should contact technical support for advice.
How to properly charge your Android phone
Basically, modern smartphones produce monolithic devices without the possibility of changing the battery. Dead battery - count your new smartphone. That is why many owners of modern devices are so anxious to monitor the health of the battery.
However, Android owners have repeatedly noticed that their phone starts to discharge faster in hot weather. The fact is that a lithium-ion battery will drain much faster if you allow the device to overheat. Therefore, make sure that your smartphone is not charged while lying in the sun or near a switched on radiator.
Also, the owners of smartphones for Android are accustomed to using low-quality chargers, as well as Chinese cheap power-banks. Despite the similarities appearance, the content of such devices is seriously inferior to the original counterparts. Therefore, no one can guarantee how many years such a charge will last, and how its work will affect your phone.
It should also be borne in mind that a traditional charger is divided into two types of charge:
- Transformer: A traditional charger that charges the device with a constant, equal amount of energy.
- Pulse: charger with built-in timer that stops the constant flow of energy after 4 hours of use. After this period of time, charging supplies the equipment with small impulses, maintaining the charge of the device without dangerous overheating.
How to properly charge your Samsung phone
As for the Korean media giant Samsung, for example, it turns out to be easy to set up correctly "Galaxy". In addition to the fact that the entire line of smartphones has software on android, which is constantly updated, and the contents of the models are getting better and better every year.
For instance, Samsung Galaxy The S9 has a 3,000mAh battery while its big brother S9 + has 3,500mAh. It is not so easy to dissipate such a charge, but it is possible.
Remember, if your device is discharged, in no case leave it in this state for a long time. One of the most common reasons for customers to contact technical service is the reluctance of the smartphone to turn on after a long discharge.
Otherwise, if you follow the above rules, there is no reason to worry. Samsung is a reliable technique.
How to properly charge your phone battery with a frog
If you still have not acquired a smartphone with a built-in battery, and your phone does not charge from standard charging, then you can always resort to using the "frog".
The frog is a charger that can replenish the energy of completely different batteries. Outwardly, this unit has nothing to do with an ordinary amphibian creature - on one side of the device there is a plug for an outlet, and on the other side there is a clamp that provides contact with the battery.
An important advantage of this device is its versatility, which is able to charge both a phone battery and a camera. The principle of operation is very simple: you just need to remove the battery from the device and connect it to the frog's contact terminals. After you plug the device with the battery into the outlet, thanks to the signal lights, it will tell you if charging is in progress. Also, the light will change to green when the battery is 100% charged.
It is also worth noting that modern models this device acquired adapters and a USB port for phones with a built-in battery.
So, to summarize:
- do not let your smartphone run down to 0% (except monthly preventive discharge);
- if it is discharged, put it on charge as soon as possible;
- try to recharge your smartphone during the day;
- completely discharge and charge the device once a month;
- do not leave your smartphone on charge overnight if you are not using an energy-saving outlet;
- do not overheat the device.
