A week ago, the unlucky owner had it while charging. And then the Internet exploded with discussions: why do smartphones burn when charging? Does this depend on the fact that the charger is not “original”? Will my iPhone crash one night when connected to a charger from AliExpress? CHIP hastened to reassure everyone who is concerned.
Yes, you can. The compatibility of a smartphone and a charger does not depend at all on whether it was produced by the same company as the smartphone itself. And if your phone supports wireless charging, then the manufacturer himself ordered it to be charged from devices from other companies. Because the Qi wireless charging standard is open and publicly available, and anyone can produce chargers using this technology. for details.
With wired charging, in fact, it’s the same thing - everything is regulated by standards. There is nothing wrong if you charge your iPhone with a charger, for example, from the well-known Belkin. And charging from the iPad too. And nothing will happen to Samsung if you charge it with a device, for example, from Huawei. Or a no-name USB cable from a PC. Why - read below.
Why can a smartphone be charged with a non-original charger?
Because mobile device batteries are designed to consume exactly the amount of energy they need to charge, or less, but not more. To do this, they are equipped with a controller that monitors this. This practice has been followed by all phone manufacturers since 2007, when the USB charging standard was adopted.
If your iPhone battery requires 1 A of current to charge, it doesn't matter what you charge it with. You can connect it to an iPad charger that produces 2A - it will only take half the current from it, and will charge at the same speed as its original one, but will not burn out. You can plug it into a USB port on your computer that gives 0.5A - it will charge half as fast, but it won't burn out either.
Thus, the law works here: consumption is determined by the consumer. Whether the phone burns or does not burn while charging depends on the integrity of the smartphone manufacturer, and not the charging. If you have a Chinese noname, into which the kind Uncle Liao installed a low-quality controller, it may burn out. And if the harried Chinese from the Foxconn factory installed a damaged battery controller in your iPhone, it can too. And if you yourself drop your phone every now and then, then even more so.
The charger itself may burn out if the manufacturer skimped on the quality of its assembly. The smartphone will not burn out - the fuses will not allow it. But to avoid this situation, it is better to take devices from serious assemblers - for example, from other smartphone manufacturers or from well-known companies that produce accessories, like Belkin.
Surely every second reader is interested in the question: “Can I charge my iPhone using an iPad charger?”
You can find a lot of unnecessary information about this on the Internet, but the answer on the Apple website is indicated as clearly as possible. I quote:
iPad devices come with a USB power adapter. This adapter can also be used with iPhone and iPod devices.
Although USB power adapters are designed for use with iPad devices, they can also be connected to all iPhone and iPod models using a cable (Lightning to USB or 30-pin to USB, depending on the model).
I personally have been charging my iPhone with an iPad charger for a couple of years now. Especially if I need to speed up charging: For example, I'm in a hurry somewhere. The charging speed increases by 1.5-2 times. I did not notice any harmful effects on the phone battery.
Nuance: Almost all iPad models come with a 10W power adapter. Only the iPad 4 and iPad Pro include a 12W adapter. And the first iPad Mini was 5 W. That is, the power adapter of the first iPad Mini is the same as that of the iPhone, so the charging speed will not change in any way.
The opposite question arises: Can I charge my iPad using an iPhone charger? Yes! Only the charging speed, on the contrary, will drop by about 2 times.
Good day, dear readers! In this post I will tell you and give examples of how to properly charge your smartphone! All the details are under the cut :) Nowadays, every person, and even more so a geek, has at least three chargers in the house for their Android devices. But everyone...
Good day, dear readers! In this post I will tell you and give examples of how to properly charge your smartphone! All the details are under the cut :)
Nowadays, every person, and even more so a geek, has at least three chargers in the house for their Android devices. But all charges have a slight difference. A smartphone charger, for example, has a current of 1A, and a tablet charger has a current of 2A.
Most people have a question: is it harmful to charge a smartphone by charging from a tablet, or vice versa? And the main question is how to properly charge your smartphone? This question, of course, arises most often among newcomers to the mobile world. But still it takes place!
There are a lot of opinions about how to charge this or that device. Some people advise discharging the device’s battery to 0% each time and charging it to 100%. And some recommend keeping the charge between 20% and 80%. Complete discharge of the battery occurs if the battery is nickel, because nickel batteries have the so-called “memory effect”. But as we know, in modern devices the batteries are “lithium-ion”, and such batteries do not have this effect. Thus, we immediately exclude the myth of “0% discharge” from our methods of charging devices :)
Which method, then, will be more gentle on our batteries?
— Recharging the device
The most gentle mode for the device’s battery is to recharge it regularly. Many people advise that the battery charge should not drop even below 50%. I would advise you to recharge the device every time the charge drops to 20%. It is best to keep the charge between 20% and 80%.
— Do not leave the device to charge “overnight”
As I said above, the battery-friendly mode is from 20% to 80%. There is an opinion that if you leave the device on charge “overnight”, this is what shortens the battery life. But this applies more to “no-name” devices (China). Since most official, branded gadgets have built-in controllers that control the charging/discharging current of the battery. When the charge reaches 100%, the controller opens the key and the voltage stops being supplied to the battery, to avoid overcharging. So leave it overnight and don't be afraid of anything!
— Discharging at 0% IS USEFUL, but not often :)
Yes, yes, exactly the discharge to zero. Although I wrote above that this is very harmful to the battery, it needs to be done once a month. Now I will explain why! All of our devices display the charge as a percentage; due to frequent recharging, this indicator will show incorrect readings over time. You can calibrate these readings in a simple way: discharging the battery to zero and fully charging it to 100%.
— Keep the device in the refrigerator!
No, this is of course a joke about the refrigerator. But I must tell you that high temperatures shorten the life of the device’s battery. Those who have really wondered about the effect of temperature on lithium-ion batteries know that if you store it at a temperature of 20 degrees Celsius for a year, the battery loses about 20% of its total capacity.
— Is it possible to charge a smartphone using a tablet charger?
We all, including myself, have at least two chargers in the house. In my case, this is charging from LG Nexus 4 (with an output current of 1.2 A) and from ASUS Nexus 7 (2012) with an output current of 2A. And no matter how much I want to, I either charge the tablet using a smartphone charger, or vice versa. So let's figure out whether such interchange of chargers is harmful?
Opinions on this matter are divided... Some say that a higher current than in the “native” charger can damage the battery or even damage the device. Others say that it is completely harmless to the battery.
But personally, I believe that the “interchangeability” of chargers has its place, and nothing will happen to your devices. Why? Because, as I already said, each device has charge/discharge controllers and a battery controller. So this same controller will not allow the device to “take” more current than it needs. If, for example, a smartphone is charged from a “native charger” with a current of 1A, then from charging a tablet (which has a current of 2A), the smartphone will also consume the 1A it needs.
IMHO
Personally, I charged my Galaxy Nexus with an ASUS Nexus 7 (2012) charger for a year, and nothing bad happened. And now I use the same charger from the Nexus 7 to charge the LG Nexus 4. And I don’t worry about battery damage, or even more so, the device failing!
What do you, dear readers, think about this? Is it possible to “interchange” chargers from different gadgets in the house?
Apple technology users are often called family. And this is not without reason, because only when using a variety of equipment with the image of an apple do you really feel how different devices work together. Accordingly, with all this, you have a great variety of chargers at home. And, naturally, one day the question arises, is it possible to charge an iPad using an iPhone charger?
Functionality check
Let's start with the fact that you don't need to have a specialized education or the necessary knowledge in electrical engineering to see when inspecting the chargers of Apple devices that the chargers are visually simply different: the power supply from a tablet is twice as large as a similar accessory from a smartphone or iPad mini . But there are situations when it would be convenient to bring one charger to work and leave the second at home. So let’s figure out whether charging from an iPad is suitable for an iPhone.
No, of course, you won’t see such a picture if your charger and cable are original. By the way, you can also use non-original ones, just don’t buy who knows what: using cheap chargers (after all, most often Chinese), you risk ruining the battery.
Can I use the charger from another device?
A moment of technical information. Large chargers - for iPad - differ from power supplies for iPhone only in amperage. In the first version it is 2A, and in the second it is 1A. They all have 5 volts. Accordingly, the power is 10 and 5 watts.
But the maximum power of the charger is indicated. This means that it can be used to recharge any device that needs less power.
Control over electricity consumption lies on a special chip inside the gadget. It is clear that a more powerful iPad can “digest” more energy, and its controller allows it to consume more power.
Conclusion: you can charge your iPad and iPhone with absolutely any 5-volt power supply. But it’s worth considering that the tablet will take twice as long to charge using a phone charger.
The latest models of smartphones running Android OS have begun to receive fast charging functionality. As for our favorite smartphone, this option is available to all iPhone and iPad users at the same time. This feature is not described anywhere, but simple experience shows that 1A standard current is far from the maximum value that a smartphone can use. By taking the power supply from the iPad and connecting it to the iPhone, we get about 25-40% faster battery recharging.
Is it possible to charge an iPad using an iPhone charger: Video
Technology has long become an integral part of the everyday life of almost every person. Computers, laptops, tablets, smartphones and so on. Young companies achieve success, and those that were pillars of past years disappear.
But among all, the “apple” company stands out - Apple. “Yabloko” has long been a sign of quality, and the products, although not cheap, are distinguished by the latest developments and elegant style.
The wide variety of gadgets has led owners to wonder whether they can use a standard smartphone. But first, a little information about the legendary company.
A Brief History of Apple
You could write several rather lengthy treatises on the history of Apple and still miss something important.
The corporation was founded on April 1, 1976 by Steve Jobs and Ronald Wayne. Apple has become one of the most famous manufacturers of software, laptops, tablets, phones, personal computers, audio players, etc.
The company's main center is located in Cupertino, California.
Apple's annual market capitalization has remained the highest in the world for several years. The company's founders created such practical and aesthetically attractive devices that a kind of consumer cult was built around Apple.
Until 2007, the company name included the word Computer. This was due to the fact that for the first thirty years Apple focused on the development of personal computers and suitable software. However, over time, Apple began to devote more time to more mobile devices: iPhones, iPads and iPods.
What is an iPad?
One of Apple's most popular gadgets is the iPad.
A lightweight and convenient tablet provides uninterrupted access to the World Wide Web and successfully performs the basic functions of a personal computer.
Undoubtedly, it will not be able to completely replace a PC or laptop: the need for recharging and the small amount of memory will not allow it to work autonomously for days. Due to the specific operating system, it is not possible to install programs on the tablet that require specific software.
Among the main differences from conventional tablets are:
- Excellent battery for longer battery life.
- High sensitivity touch screen.
- An operating system that responds quickly to requests.
- Easy installation of programs.
But the gadget is not without its drawbacks:
- A closed file system that does not allow developers to change it, similar to the Linux OS.
- Lack of built-in USB ports.
- Lack of a standard Flash player from Adobe.
How is an iPhone different from a smartphone?
If everything is clear with tablets, then how does the iPhone differ from thousands of other smartphones?
Owners of Apple smartphones note that the main advantage of the iPhone is its operating system. Unlike Android, whose updates are installed on phones of any brand, iOS is designed specifically for Apple. Thus, random “lags” of the system are practically excluded.
Applications downloaded through a special store are suitable for every smartphone. iOS is less susceptible to viruses than other operating systems. The elegant shape and body of the devices are not only beautiful, but also durable.
A little about batteries
Before answering the question of whether it is possible to charge an iPhone using an iPad, you need to learn a little more about the properties of the battery in these devices. Since the days of the first telephones, the material from which batteries for smartphones and tablets are made has changed. Batteries have become lighter and more practical.
The Apple devices listed above use lithium-ion polymer batteries. Due to the fact that lithium is one of the lightest metals, the battery is lightweight but practical.
Their main difference from nickel batteries is the ability to charge the battery at any time. Also, gadget owners do not have to worry that incomplete charging can damage the battery and reduce its operating time.
To ensure proper operation of an iPhone or iPad, developers recommend fully charging the battery once a month and then completely discharging it. This will help keep the electrons moving.
Is it possible to charge an iPhone using an iPad charger?
Owners of Apple gadgets often lose the charger from their smartphone or tablet. After that, they try by all means to find out whether it is possible to charge an iPhone using an iPad charger, and vice versa.
Some people think that if it’s from an iPhone, it can ruin the battery. Some people sincerely believe that one gadget does not fit the parameters of others.
It's time to dispel the myths and find out the truth.
Pros of the solution
Smartphone owners note that you can easily charge your iPhone using an iPad charger. The original accessories and devices fit together perfectly, and there are simply no connection problems.
The main advantage of this method of charging an iPhone from another Apple charger is the time savings. The charger that comes standard with your iPhone has a maximum output of one ampere. When charging from an iPad - two amperes. Thus, the time to fully charge the battery will be halved.
Also, if you use an iPad, you will no longer need to carry multiple chargers with you. This plus will be appreciated by those who need to constantly carry a smartphone, tablet and laptop with them. There are several cables in the bag that always get tangled.
However, is it possible to use an iPhone, since it is a more powerful device? Of course, it is possible, but it is worth noting that then the time to fully charge the battery will increase significantly.
Smartphone owners don't need to worry that a more powerful iPad charger will harm their iPhone. The maximum current indicated in the application does not play a big role, since smartphones have built-in controllers that do not allow more power to pass through than the gadget requires.
Minuses
But are there any disadvantages to this charging method? Users did not notice any significant deviations in the battery life of phones or tablets.
Most of all the information about how to charge your iPhone without damaging the battery's properties comes from the fact that almost all modern smartphones have batteries that do not last long. The owners are trying by all means to preserve them.
Thus, information has emerged that if you charge your phone using a tablet charger, then within a year the smartphone’s battery will become almost unusable. However, they forget to mention that, one way or another, most owners of Apple smartphones change batteries after a year.
Thus, there are no significant disadvantages from such charging.
Information from official sources
Undoubtedly, only the manufacturer will provide the most complete information about whether an iPhone can be charged using an iPad charger.
The support service on the official website reported that iPads usually come with a charger with a USB interface. This same adapter is great for iPhone and iPod.
Are other gadgets suitable?
Many owners of mobile devices at some point have a question: “Is it possible to charge an iPhone using an iPad, as well as from a computer via a cable?”
You can also charge gadgets from this company via USB connected to a computer or laptop. But first you need to figure out what ports were built into the PC. Modern personal computers are equipped with three types of USB ports: 1.0, 2.0 and 3.0.
The maximum current strength in the first two types reaches five hundred milliamps or two and a half watts. The latest generation of ports output up to nine hundred milliamps or five watts. Charging time for iPhones and iPads will vary depending on battery size and port type.
The first and second generation USB ports deliver almost half the power, which means that the charging time will be almost twice as long as when using the third generation ports.
It is very easy to distinguish the third generation port from the rest - it is blue.
It turns out that charging Apple gadgets is very simple. You can use both original accessories and a standard USB cable connected to a personal computer.
