Original charger for iPhone. What kind of chargers can you use to charge your iPhone? Simple rules! Should I leave my iPhone charging overnight?

You have repeatedly asked us about the labeling of power supplies that come with Apple equipment:

Tell me what all these volts, amperes, hertz, resistance and other parameters of chargers mean. In most cases, people ignore these important parameters; only appearance remains the fundamental factor when purchasing. I would like to be a little more enlightened on these issues.

It's time to dot all the i's.

Modern consumer electronics do not require the user to have virtually any knowledge from the world of physics and electronics. Just buy it, take it out of the box and use it.

However, knowledge of certain parameters, understanding of certain processes and properties will help you choose the right product, use it wisely and not expose the equipment to the risk of failure.

iPhone power supply

This is a standard European power adapter that has been included with all iPhone models and some iPad mini models for several years. Chargers from other regions differ in appearance, but have similar characteristics.

Input

All symbols after this inscription describe the necessary input parameters for the operation of the device.

100-240 V

This inscription indicates that the device is designed for a voltage range from 100 to 240 V. Such power supplies are universal and are made to American (110 V) and European (220 V) voltage standards. When using adapters, European charging can be used in America and vice versa.

"~" symbol

Indicates that the power supply is designed to be connected to AC power. All electrical appliances connected to the network are designed for alternating current.

Devices that operate on batteries or accumulators are consumers of direct current, because the battery is a source of direct current.

50/60 Hz

This parameter means the frequency of alternating voltage in the electrical network.

In Russia, this indicator is 50 Hz at a voltage of 220 V, in most countries of North and Central America a frequency of 60 Hz is used at a voltage of 110-115 V, and, for example, in Korea the frequency is 60 Hz at a voltage of 220 Volts.

And this parameter indicates the versatility of the iPhone power supply. But it is worth saying that frequency, unlike voltage, is critical only for devices equipped with electric motors. Thus, hair dryers, meat grinders or juicers produced for sale in different countries will have different operating frequencies.

When operating in an unsuitable power supply (with a different frequency), the devices will not be able to produce the maximum declared power, and with long-term use, the motor may fail.

This parameter also relates to the input voltage and characterizes the current strength. The higher this indicator, the greater the current the adapter can produce at the output.

This parameter does not impose any restrictions on the connection.

Output

All symbols after this inscription describe the output parameters of the power supply.

The power supply essentially converts the voltage from the mains in the range of 100 to 240 Volts into the 5 Volts that are typical for the USB standard. The same 5 Volts can be obtained by connecting a smartphone to the USB port of a computer or laptop.

Symbol ⎓

The output current will no longer be alternating, but constant, which is necessary to charge the battery. The symbol “three dots under the line” on household appliances indicates unidirectional current.

The current in a given circuit has a constant direction from points with higher potentials to points with lower potentials. In such a circuit, polarity appears, that is, of the two contacts used, one is the positive pole and the other is the negative pole.

The most recent indicator is the most important for the average consumer.

The output current of 1 Ampere is designed to charge a battery of a certain capacity. The larger the battery capacity, the longer it will take to charge at that current. Conversely, when using a power supply with a higher amperage for a small battery, we will get a shorter charging time.

A power supply with an output current of 1A can be used with any device, but it will take a very long time to charge the iPad.

iPad power supply

Apple tablets come with different power supplies. In the boxes with iPad 1\2\3\Air\Air 2\Pro 9.7″, iPad mini 2\3\4 you can find a power supply for 10W, and with the iPad 4 and the large iPad Pro they put 12W charging.

Most of the parameters match the parameters of the iPhone adapter. The input specifications differ from the current to 0.45A and 0.5A, respectively. From the weekend - the output voltage will increase slightly to 5.1-5.2 V.

The main difference is the increased output current. Instead of 1A, iPad power supplies have 2.1A and 2.4A.

This allows you to charge larger batteries in tablets, and when connected to an iPhone, it will give less charging time.

MacBook power supply

Adapter Apple USB-C Power Adapter 29W comes with new Apple laptops that come with USB Type-C ports. If you have an adapter, you can also charge your iPhone, iPad or iPod Touch.

For 5V consumers it produces a current of 2.4A. This figure is greater than the iPhone adapter and power supplies from most iPads and is equal to the charging current from a large iPad Pro.

Apple does not prohibit using power supplies from some devices to charge others, although sometimes this leads to a little more wear on the battery.

Armed with the knowledge from this article, you can decipher the inscriptions on the power supply from any gadget, smartphone, tablet or laptop.

Don't forget that we publish a lot of interesting things in

Did you ask if you can charge your iPhone using an iPad charger? Which adapter should I choose? Is it possible to use the phone while it is connected to the outlet? Now I'll tell you everything.

How to charge an iPhone

You cannot charge your iPhone incorrectly; it can be charged quickly or slowly. What does this depend on? From a specific smartphone and power supply.

Charging the iPad helps. But not always.

A minute of statistics: iPhone 5s consumes 1A, iPhone 5 takes the same. Connecting them to the iPad power supply is no use. But the iPhone 6+ and 6s+ eat up 2.1A, so it makes sense to connect a unit from the iPad. Let's check it out.

We take two iPhone 6+, connect a standard 1A charger to one, and connect a 2.1A iPad unit to the second. In 10 minutes the first one was charged by 4%, and the second by 10%, profit! To speed up charging, use airplane mode, the difference is small, but the method still helps.

Charging the battery while in use

You can use the device while charging, it will just take a little longer to charge.

Current strength decides

When buying a multiport charger, pay attention not only to the current strength, but also to the support for Quick Charge, this will greatly speed up the process. This cool theme doesn’t work for iPhone, but if you have a Galaxy S6, then feel like a king.

The same principle applies to Power Bank: it is better to take a charger that produces a current of 2A. It won't kill your smartphone, but you can always charge your tablet. Whereas with an external 1A battery this situation is basically impossible.

iPhone not charging? Check your Lightning cable

Bought a Chinese Lightning for 100 rubles at a stall, but your iPhone refused to charge? Before purchasing, be sure to look at the packaging; if you take proven, certified Belkin or Griffin products, then everything is ok. But when the box doesn't say "made for iPod, iPhone, iPad", then you can fly with the cable.

No need to replace the battery

A modern battery has a lifespan of about 1000 cycles, which is about 3 years of operation. So you’d rather exchange your old phone for a new one because you’re just tired of it, than really start to suffer because of a dead battery. Unless, of course, you killed it with Chinese wires and a worthless power bank.

To prevent your iPhone from burning

Achtung! Don't charge your iPhone while lying in bed. Just imagine: you stare at the screen, fall asleep, the phone falls on the bed or under the pillow, under the blanket, overheats and FIRE. Don't do that.

Every iPhone owner asks the question: how to properly charge the device and at the same time ensure long battery life. In this article, we have collected tips and tricks that will help you learn more about this.

Due to improper use of the smartphone, the user may unknowingly shorten the battery life. This happens every day, and in order to correct the situation, it is worth familiarizing yourself with the unspoken rules for extending battery life. Let's consider what negatively affects its work.

Extreme temperatures

Any gadget, be it a phone, tablet or computer, is sensitive to both too low and too high temperatures. This is justified by the absence of a heating or cooling function for the device in the internal configuration. Consequently, the “filling” of the iPhone may simply freeze or heat up and fail, or in the worst case, catch fire.

• the screen was not exposed to direct sunlight;
• the smartphone was not in a closed, stuffy or hot room (for example, in a car in the heat);
• did not charge in places where there is no ventilation, no access to air, because The device will not cool down.

Rule #1: Do not use or charge your device in extreme temperatures.

Non-original charger

The standard iPhone power adapter has a voltage of 5 volts (V) and a current of 1 amp (A). Complete with a certified cable, the phone charges in an hour and a half. If the equipment turns out to be non-original, both the battery and the phone may suffer.

It's all about the manufacturers - some provide quality products, others may give the user incorrect information about the characteristics, i.e. indicate the standard 5V and 1A, and sell the product with values ​​that will be greater or less than those indicated.

Even with a slight increase in voltage, for example, by 4%, the battery capacity will decrease twice as fast from cycle to cycle. Typically, the differences are regulated by the built-in PCIM controller, which is responsible for supplying current.

Counterfeits may not have such a controller, which can result in high output voltage. This can damage both the charge controller in the iPhone and the battery itself. It is better to protect yourself from problems and use the equipment provided by the manufacturer.

Rule #2: Use the original adapter.

Chinese charging cable

The situation with Lightning cables is more complicated. Many iPhone owners have heard that such cables break easily and are not cheap. Its plug is equipped with a special chip with which the iPhone recognizes its original wire. Finding such an analogue is quite difficult.

However, the Chinese were able to clone this chip, selling similar cables for pennies, which is how they lure users. It is worth assuring that such a product may work, but for a very short time. We recommend using cables that have passed Apple certification - this way you will avoid additional damage to the device.

Rule #3: Buy only certified cables.

Full discharge

The smartphone uses a lithium-ion battery, and it is very sensitive to the charge dropping to zero. This can cause significant damage, resulting in a reduced service life. This is all due to the depth of discharge - the ratio of the discharged capacity to the nominal one.

For example, if you use up 100% of the charge and do this constantly, the battery in this state can withstand about 500 cycles. If the phone is only half discharged, the number of cycles instantly increases to 1500. It turns out that the more you discharge the battery, the less it will last you.

Rule #4: Don't completely drain your iPhone.

Charge up to 100%

When the device's charge reaches its maximum, the battery is in a high load state. This is due to the fact that each cell of a lithium-ion battery is charged to the required voltage, therefore, the higher the charge, the shorter the lifespan of one battery cell.

Of course, this does not cause as much harm as completely discharging it, but it is better to charge the iPhone in small portions - at every opportunity, even by 10-20%, but often and painlessly. The optimal charge level is considered to be 40-80%, so you can charge the phone starting from 50% and ending with no more than 90%.

Rule #5: Charge your device more often.

No battery calibration

When using the phone for a long time, the charge indicator inevitably goes down. This is due to improper operation, frequent discharge, incorrect operation of the smartphone itself (sudden shutdowns, damage to internal components, etc.), or charging the battery haphazardly. A complete discharge is appropriate if the iPhone displays an incorrect charge indicator. Then it’s worth bringing the phone first to 100%, and then to zero, or vice versa.

This process is called "calibration". Sometimes you have to do it in order to bring the battery back to life. For prevention, it is best to do this procedure no more than once a month.

Rule #6: Periodically discharge your iPhone.

Is it possible to leave an iPhone on charge all night?

Many people are debating whether it is safe to charge an Apple smartphone overnight. Therefore, we conducted our own investigation. In fact, long-term charging at a constant value of 100% does not cause much harm to the battery. When the iPhone is fully charged and connected to a charger, it runs on AC power. At this time, the smartphone is not charging or discharging, and the battery is in a “feeding” state.

If the charge drops by 2% during overnight charging, current begins to flow through the cable. This does not cause much harm to the battery, because this happens infrequently - about once a week. In other cases, the current is kept at a stable level, therefore, the device does not “fry” at night.

Is it possible to charge an iPhone using an iPad charger?

It’s worth answering right away: yes, you can. This is possible thanks to the special proprietary charge controller built into the iPhone. With it, the charging speed is deliberately reduced after 80% in order to control the optimal current supply. He is also responsible for “working from the network” and constantly monitors the health of the battery. For this reason, when charging from an iPad adapter, the battery is not loaded, despite the fact that it has a voltage of 5 volts and a current of 2.1 amperes.

In total, the charging power of the iPad is twice as much as the adapter from the iPhone. It is logical to assume that in this case the smartphone will charge faster, but this is not true. In older iPhones, regardless of the current supply level, the built-in controller does not allow you to receive more charge than what is written in it. In new models, starting from the sixth generation, the manufacturer was able to speed up the process a little, but only slightly.

Long term storage

If stored for a long time, the device may wear out considerably - some functions will become worse, the battery will lose its capacity, etc. To prevent this from happening, you must follow the following recommendations:

• Charge your iPhone up to 50%;
• turn off the device completely;
• store in a dry place where the temperature does not reach +32 degrees;
• Bring your iPhone's charge to 50% every six months.

The device should be charged with half the battery capacity, because a full charge can significantly reduce the service life. The same applies to his absence. At 100% the primary capacity is lost, at 0% the phone goes into deep discharge, and this harms the battery.

The company has prepared relevant recommendations especially for its customers, which are especially worth listening to:

• You shouldn't charge your iPhone together with the case, because... this may cause the phone to heat up;
• the same can be said about using a smartphone in cold weather;
• Use only certified accessories marked MFI (Made for iPhone) on the supplied box or on the product itself;
• Before long-term storage, charge the phone halfway and turn it off.

It is worth noting that Apple only recommends, and does not tell users how to handle the company’s devices. According to iPhone owners, it is not necessary to strictly follow all the rules for battery use. The manufacturer has created special built-in controllers so that the owner does not damage the battery through his actions. However, the tips described above will somehow help extend its life for many years.

Video instructions

You can watch detailed video instructions on how to properly charge your iPhone. The created video will help users better understand the implementation of all the provided actions.

Results

Usually we don’t monitor how we use the battery and don’t notice the damage we cause to it. However, you shouldn’t worry too much about this and constantly worry when the gadget turns off on its own initiative or due to the user’s inattention. Apple carefully monitors the quality of its products.

Therefore, even with normal use, the battery will function as before for the standard three to four years. There is no perfect plan for how to increase battery life. Just don't overuse the capacity, always keep an eye on the charge and beware of extreme temperatures.

The latest Android smartphones have a fast charging marketing feature. With the Galaxy S5, Samsung's fast charging technology has gone super-fast. Motorola has implemented a charging technology in the Droid Turbo that can charge in 15 minutes for up to 8 hours of use. HTC has a Rapid Charger 2.0 charger that can charge devices in its 2014 lineup 40% faster.

The new iPhone 6 and 6 Plus have larger batteries, but no additional technology to charge them faster. However, there is a way to quickly charge the capacious batteries of the iPhone 6 and 6 Plus (and other models). This article will discuss it, as well as how it affects device batteries.

In fact, the solution was always literally in front of our eyes - a 12-watt iPad charger that produces a current of 2.1 amperes. The question arises, why doesn't Apple talk about this feature separately and can it harm your smartphone's battery? As for the first part of the question, it is better to ask it to Apple’s PR department, but the second part can be answered by gleaning information from this section of the company’s official website. It says that the iPad charger is compatible with other Apple gadgets, including the iPhone. It turns out that the company is aware of this possibility and confirms it.

In fact, the charger settings provide a slower charging process than is possible. Simply increasing the charge current from 500 milliamps (or 1 amp) to 2 amps (iPad charger) will significantly speed up the charging process.

You may ask, what consequences could this cause? Increasing the charge current will cause the battery to heat up more, which will also reduce its service life. Therefore, most people would consider charging an iPhone using an iPad charger a bad idea. You can dispel doubts about this by understanding the basic principles of charging batteries.

Isidor Bachman, founder and head of Cadex Electronics and author of the book “Batteries in a Portable World,” in his book talks about the key indicator C-rate, which determines how much charge a battery can safely receive or the speed at which The battery may be charging/discharging. To determine this coefficient, you simply need to take the ratio between the amount of charge and the battery capacity in milliamps. For example, for an iPhone 6 when charging from an iPad charger, this figure will be 2100/1810 mA or 1.16 C. For an iPhone 6 Plus it will be 2100/2915 mA or 0.72 C.

The batteries of most mobile devices have a charge factor of approximately one. Thus, the coefficient calculated above for the iPhone 6 and 6 Plus is in a safe range. Bachman says that battery manufacturers recommend using chargers that provide a rate below 1 C, but such a slight excess is not at all a cause for concern.

There is one more point regarding fast charging of the batteries of our gadgets. Each of them has a special PMIC controller responsible for the battery charging process. It “talks” to the charger you are using and requests the specific amount of charge the battery needs. That is, theoretically, this mechanism is capable of protecting your iOS device, since Apple clearly indicates the charging parameters. This technology is supported by Qualcomm controllers, which are used in the iPhone 6 and 6 Plus, so we can safely say that accelerated charging will not damage the smartphone and will not lead to a significant reduction in its resource.

From personal experience, I can say that I have been using this lifehack with iPad charging since the days of the iPhone 4. I simply charged the phone with the adapter that was at hand and at home, most often it was the adapter from the iPad. The charging process is more than doubled, and if you haven’t completely discharged your iPhone, it will be able to charge to 100% within an hour. During this time, I changed several devices, but on none of them did I notice any harmful effects from such charging. Yes, the battery heats up more, but no one forces you to hide your iPhone under your pillow while charging, right?

The problem is that Apple is a very self-centered company. Therefore, if users should buy something, it should only be with their logo. And thanks to this policy, the iPhone has several interesting lines in its program code. They forbid him to use a cable that is not produced by the parent company. And the cost is quite high. But the proprietary cord contains a special chip, which the device must analyze in order to work.

How to charge an iPhone with a non-original wire

But despite all Apple’s tricks, you can still use a non-native USB cable. Although you will have to suffer a little each time for this. So, a list of actions that need to be carried out so that your iPhone still “eats” the non-original plug and starts charging:

1. Connect the charger with the cable inserted into it into the outlet.
2. Take the wire plug and insert it into the smartphone. The latter must be blocked.
3. A warning will appear that you need to close. To do this, you need to pull it to the side.
4. Only after this - unlock the device.
5. Reject everything the iPhone complains about again.
6. Without blocking the device, remove the cable plug from the Lightning socket and immediately return it to its place.
7. And again, reject all the windows with which the miracle of Apple technology will notify you.

After this simple list of actions, the device should begin to receive energy.

Is it safe to charge with a non-original cable?

Such manipulations using a cheap cable, which for some reason is still not equipped with a normal chip (for example, like wires from Remax), can be very expensive for its users. The relatively new iPhone 5 has a small but very unpleasant module among all its hardware. It is almost invisible to the eye, but it can really ruin your life.

This little rascal is called U2 IC. It analyzes which cable is currently being used with the smartphone. And if for some reason he doesn’t like this cord, it simply breaks. And if this chip breaks, you will have to either get rid of the iPhone or repair it.

What problem does it cause? It's simple. Without an adequately functioning U2 IC, the device is unable to receive power. Even if it regularly enters the gadget, it does not reach the battery. As a rule, the owners think that the battery is damaged, and then they go to change it. But this does not help - as soon as the new battery is discharged to zero, the smartphone will no longer show signs of life.

So what should we do?

Use only high-quality non-original iPhone cables! All manufacturers who respect themselves and their name have long been aware of which chip inside the plug is responsible for initialization in the device. And they even learned to fake it. And therefore, you should not take Chinese “noname” wires from the nearest kiosk. They are certainly cheap and available. But won't it be more expensive to repair your mobile phone later?

It’s better to spend a little money and buy one, which is a little more expensive than the Chinese one, but still cheaper than the original one. There is a lot to do in this area. Many manufacturers offer their services:

• Belkin company. There is no need to even doubt this - this company, according to assurances, is certified by Apple themselves. Consequently, your gadget will not suffer from the use of wires purchased with this brand;
• Remax company. Their products attract attention; it is impossible to pass by such a wonderful purchase. Their big bonus is that they don't stop at boring monochromatic cables. The Remax assortment includes dozens of different wiring. In the catalog you will find everything, even fabric-braided data cables, which remain operational longer than regular ones;
• manufacturer named Just. Severe and solid models for mobile phones that will not become a problem for the user. They are produced with a leather braid, which is more reliable than even fabric. There is no need to talk about quality - it definitely exists. Not a single gadget, according to user reviews, failed while Just was working with it.
