Tell me, is it possible to charge an iPhone from a computer?
Of course you can. Charging will take a little longer, since the voltage coming from the computer is less than from the original charger. The advantage of charging from a computer is very good, since less current is supplied to the charge, the battery will last longer, and batteries for such devices are quite expensive. You've probably already seen swollen batteries? They were charged incorrectly, perhaps with chargers that exceed the norm for this particular model.
Experts have found an unusual feature in the new version of iOS 12. It turned out that if the iPhone is not unlocked for more than an hour, the Lightning port will not be available even for charging, AppleInsider reports.
Thus, after installing the fifth beta version of iOS 12 firmware on a test iPhone, experts found that the system automatically turns off the smartphone port after an hour of sleep mode. For example, if you put the device on charge to the computer and do not remove the lock, after an hour the device will finish charging and turn off the physical port.
It's all about the security of user data. Previously, Apple announced protection for the iPhone, which consisted in the fact that the Lightning port turns off if the smartphone is not touched for more than an hour. However, experts could not assume that after 60 minutes the iPhone would also turn off charging.
In addition, the charging speed of quantum batteries directly depends on the number of blocks they consist of. The thing is that the more blocks are used in the battery design, the faster the mobile device will charge.
Cleaning the connector
Carrying your phone in a pocket or bag without a case causes dirt to accumulate inside the connector to which the charger is connected. There are no sealed plugs on the iPhone, so the only option is to clean the port in a timely manner.
Therefore, before changing the cable or contacting a service center for diagnostics, make sure that the connector is not dirty. Using a regular toothpick, carefully clean the connector, removing any accumulated small debris. Also, using a cotton swab, rubber band and alcohol-containing liquid, clean the contacts of the charging connector if dirt or oxides are observed there.
Pros and cons of wireless charging for iPhone 10
The main advantage of wireless charging is ease of use. The owner of an iPhone will not have to look for a power outlet for long, especially if the person is not at home. In addition, wireless charging does not affect battery performance at all.
However, wireless charging has many more disadvantages. The main ones are:
- Speed. Unlike other charging options for iPhone X, the wireless method will be the slowest.
- Price. To purchase a “home” charger, you will have to fork out almost $100. This is how much original and branded accessories from Apple cost.
Cable check
If there is another original cable, then try charging the device using it. This way you can determine whether the problem is with the phone or the charger.
If you use a non-original Chinese cable, a message may appear on the screen stating that this accessory is not supported. The same notification appears if the lower cable is damaged, therefore:
- Try charging your phone with an original charger.
- If your iPhone still won't charge, contact a service center.
Charging from a computer
If you want to charge your iPhone from a computer via a USB port, but charging is not happening, then try ending all processes on your smartphone that may consume energy. Turn off Wi-Fi, close applications.
In general, it is not recommended to charge your iPhone from a computer: the USB interface was created for data exchange, not energy transfer, so use a regular charger that plugs into a power outlet. The iPad, for example, in principle does not charge via USB, only maintaining the current charge level.
Is it possible to charge iPhone 11 with a non-original unit?
Most often 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.

Restarting the system
Sometimes a forced reboot of the iPhone helps fix the charging problem. It is used in extreme cases when internal system errors prevent the smartphone from working normally.
- Connect your iPhone to an electrical outlet.
- Press the Power and Home buttons at the same time. Hold until the device reboots.
After the system starts, you will see that the iPhone has started charging.
For other phones, look for the reboot method in the instructions or on the Internet.
What to do if iPhone does not charge from laptop or PC
Phones and tablets can be charged either from a wall outlet or from desktop computers and laptops. In fact, most devices that need to be charged can be charged by simply connecting them to your laptop or PC. With a laptop, you don't even need to turn it on.
You can turn it off and still charge your device. Charging is mostly a simple process, but sometimes the phone won't charge. If you're trying to charge your iPhone but it's not working, try the following.
Let the iPhone charge
Now the main thing is to give the device time to recharge. Many at this time are already packed, standing on the threshold and don’t know what else to do. They start playing games or just scrolling through photos. So the smartphone may not only take longer to charge, but may not even receive a percent of the energy.
It’s better to review your collected things again, make a plan for the day, spin your favorite spinner.
Basic checks
Before attempting any of the fixes, first perform the following checks:
- Make sure the data cable you are using is not damaged. Ideally you should use the original cable, but third party cables will work just as well as long as they are not damaged.
- Your iPhone's connection port is intact and clean. Dirt can accumulate in the port since many people tend to keep their phones in their pockets. Make sure the port is clean and has no visible or obvious signs of damage.
- Plug it into a wall outlet to make sure it's charging. If it doesn't, the problem may be with your iPhone, the wall adapter, or the charging cable you're using.
- Connect it to at least one other computer to see if it charges or not.
If everything works, try the following fixes.

Why iPad won't charge from computer:
The fact is that in order to charge an iPad, a current of 1.2 A is required, and the USB ports of the vast majority of computers and laptops produce no more than 0.5 A.
What to do if the iPad does not charge from the computer (5 ways that will definitely help you solve the problem):
1)We try to connect the USB cable to different ports of the computer
Try connecting your iPad's USB cable to different ports on your laptop and computer. The fact is that the current strength supplied by the computer ports can differ significantly. For example, it may be different for USB outputs located on the front wall of the system unit and on its rear wall. The same rule applies to laptops.
2)Putting iPad into sleep mode
By putting the iPad into sleep mode, you will ensure that it still charges. True, it’s unlikely that the charging speed will suit you. When using this advice, remember that the iPad will only charge if the laptop or computer is turned on.
3)We turn to our Apple relatives for help
Problems with charging your tablet can be avoided if you have Apple products such as Mac Mini, iMac, MacBook or MacBook Pro. These devices are equipped with powerful USB ports that can provide the tablet with the required amount of energy without any problems. While charging, you can even use the iPad.
4)We purchase a special USB cable
If you no longer want to rack your brains over how to charge your iPad from a PC, purchase a special cable, which is a 2nd USB adapter. In order to charge the tablet, you only need to connect two USB connectors of the adapter to two ports on the computer. The remaining connector of the adapter is intended for connecting an iPad using a standard cord.
5)Download and install a Windows program that allows you to increase the current strength
Today, the most popular are three programs that increase the current from 0.5 a to 2 a: Ai charger GIGABYTE ON / OFF charge i-charge
You can download a free program that increases the current in USB ports below.
You’ve had breakfast, you’re about to leave home, you’re already dressed, you’ve collected the necessary things, you pick up your iPhone and see that there’s 10-15% charge left. Is the situation familiar? It’s good if you travel by car, you can recharge your smartphone along the way, but in other cases it’s just a tragedy.
You have to look for a PowerBank, make room for it in your bag and manage a string of wires that allow you to charge your smartphone and use it on the go at the same time.
Until Apple “invented” fast charging, the correct algorithm of actions is as follows:
Change charging port
All laptops have at least one charging port. This is a simple USB port that can supply power to a connected device. However, all USB ports can supply power, the charging port provides more power and allows devices to charge quickly (if supported) and charge even when the laptop is turned off.
The charging port is indicated by a lightning bolt next to it, although in some cases it may not be present. Read your laptop's manual to determine which port is the charging port and make sure you're using it to charge your iPhone. If you are already using the correct port, try using a different one with your laptop turned on.
Universal charging - power bank
For traveling I got this cool device. This is not just a 10,000 mAh power bank, there’s a lot of that stuff, but it also comes with a charger ! Yes, yes, there are two USB-A ports (or USB-A and USB-C, you can choose the desired option when ordering) with a maximum power of 45 W (15 W for USB-A and 30 W for USB-C). That is, you can charge at the same time, for example, an iPhone and an iPad, or an iPhone and a MacBook Air, there will be enough power.
She's much smaller in real life
I took it straight away from USB-C so that I could charge my wife’s MacBook Air
The main thing is that for the price of a good power bank you get not just a box with a battery, but also a charging adapter. If you are going to go somewhere, this is a very useful device; take both the charger and an external battery with you. The size is also pleasing, even smaller than the iPhone 11 Pro . Well, isn't that great?
I think this is downright brilliant. Previously, it was necessary to take a separate power bank and a couple of chargers, but now you can get by with one such device. Pay attention to coupons , you can get an additional discount with them.
Universal charger and external battery for iPhone, iPad and Mac
Check disabled USB ports
If all the above fails and you have already verified that the iPhone charges when connected to another computer, check if the USB ports on the system are disabled. You can do this from Device Manager.
Right click on each port and make sure none of them should be enabled. If the port really needs to be activated, turn it on and see if the iPhone starts charging.
And if you lack passion, look into an intimate store. There you will find a full range of everything you never even dreamed of.
Charging case for iPhone
A special battery case has become a very popular product of our time, after putting it on the iPhone begins to rapidly replenish the battery capacity. The device has a capacity of 2200 mAh, which is enough to extend the life of the smartphone by a good 1.5-2 days. An important point is to take care of charging the case itself in advance, otherwise it will turn into only a protective shell and, I would like to note, a very weighty one. The design of the accessory is laconic - one “turn on” button and an indicator panel displaying the remaining battery. The cost of the gadget is reasonable – it sells for between 800 and 2,000 rubles.
Connecting to a power source
If you're having trouble charging your iPhone 8 or later wirelessly, try charging your device first using the included USB adapter and cable. If it will charge this way, read the article about wireless charging. If you are using an accessory from another manufacturer, make sure it is certified by Apple.
To charge your device, follow these steps.
- Connect the supplied USB cable to the device.
- Connect the cable to one of the power sources listed below.
Wall power outlet
Connect the USB charging cable to the USB power adapter, and then plug the adapter into a power outlet.
Computer
Connect the charging cable to a USB 2.0 or 3.0 port on a computer that is turned on and not in sleep mode. Do not use USB ports on your keyboard.
Charging accessory
Connect the cable to a powered USB hub, docking station, or other Apple-certified accessory.
When your device is charging, a lightning bolt icon appears next to the battery icon in the status bar, or a large battery icon appears on the lock screen.
How to properly charge Apple devices
It would seem that everything is simple - you insert the charger cable into the gadget and into the power supply, and electricity will do the rest of the work. However, this is misleading and recharging your device in this way can harm the battery.
Manufacturers and specialists, through research, trial and error, have created a number of guidelines for the operation of iPhone, iPad and iPod batteries. This also applies to other devices whose batteries are based on lithium-ion.
- Carry out a full discharge-charge cycle of your phone no more than once a month. To do this, you need to completely deplete the battery reserves, then start the charging process, and, without turning on the device, bring the charge level to 100%.
- Charge your phone as often as possible. The recommended battery level should be kept between 40-80%. Frequent charging means the movement of electrons inside the battery and the absence of the possibility of rendering energy-intensive elements unusable.
- Do not bring the battery charge to 100% (except for the cases described in the first paragraph). Your device runs on battery power, not mains power. Once the maximum charge is reached, the battery continues to be used, and this leads to its discharge by 1% or less, which starts the charging process again. Such microscopic charging of the battery harms it, so it is not recommended to leave your device to recharge all night or all day.
- Maintain temperature control, especially when charging your phone. Increasing and cooling temperatures lead to physical deformation of battery cells. The optimal temperature for active use and charging gadgets ranges from 20–24°C.
Is it possible to charge an iPhone using an iPad charger?
There is no prohibition against using “foreign” charger cables to power your iPhone. But it is worth remembering that the plug must fit the phone connector. For example, it is highly not recommended to try to charge an iPhone using a charging cable from a thin Nokia and other plugs that are not suitable for this purpose. You also need an operating voltage of 5V, but this is the international standard.
The output charging voltage for iPhone, iPod and iPad is the same and is equal to the operating voltage of the USB port - + 5V. What is written on the charger is the maximum current it can produce. But that doesn't mean she always gives him away. Any Apple device has a special charge processor that optimally selects the current to charge the battery. It also limits the charging current at a certain maximum level if the battery is severely discharged. The only difference is that the iPad's battery is larger than the iPhone's and therefore, to reduce charging time, the iPad's maximum charging current is 2A instead of the iPhone's 1A. Naturally, the charger must provide this current. That's why it's more powerful on the iPad. As a result, the Iphone can be safely charged by charging from the Ipad, since the charging current of the Iphone is less than what the charger can produce. By the way, on the contrary, you can also charge an iPad using an Iphone charger, it’s just that the charge will be 2 times slower, since the Iphone charger cannot produce the required 2A.

How to charge your phone from a computer, in a car or on a train
The charger is divided into two parts: a power supply and a cable with a USB connector. As a result, anything that has a USB input and is connected to a power source can charge your device.
The simplest example is computers and laptops. You need to connect the devices using a charging cable and wait for the required charge level. It is important to remember that a laptop that is turned off or in sleep mode will not charge the smartphone. Although for sleep mode this function can be disabled:
- Right-click on the “Computer” icon and select “Manage” from the drop-down menu.
Through the context menu of the “Computer” icon, go to “Management” - In the left column, click on “Device Manager”.
- Open the USB Controllers tab.
In "Device Manager" find "USB Controllers" - Double-click the left mouse button to open the properties of each item called “USB Root Hub”.
Double-click the left mouse button to open the properties of “USB Root Hub” - Go to the “Power Management” tab and uncheck the “Allow the computer to turn off this device to save energy” checkbox. And confirm the change with the “OK” button.
Uncheck "Allow the computer to turn off this device to save energy" and save the changes
Now your laptop will charge smartphones and tablets even in sleep mode.
When it comes to cars, not many of them have direct facilities for charging your phones. But almost all of them have cigarette lighters, which means that with the help of a simple device called a “bullet,” you can connect your phone to a power source.
Using a cigarette lighter adapter, you can charge your smartphone in the car.
The possibility of using the electrical network in trains is fully realized. Each carriage, be it a reserved seat, a compartment or a SV, has the most ordinary sockets. Of course, their voltage varies within a certain range, and this affects the charging speed of the gadget. The main thing is that you only need a cable and an AC adapter to start recharging the device's battery.
Using a standard charging kit, you can charge your phone on the train
How to use wireless charging
Not the newest technology, which only recently found application in the charging system for portable devices. If we omit the unclear terminology, wireless phone charging is based on the principle of inductance.
The wireless charger consists of two parts:
- magnetic pad;
- phone case with plug.
Using a special case, you can charge your iPhone with a wireless charger
As a result, we get a phone case with which a magnetic pad can charge the device.
The advantages of this type of charging include the fact that the absence of a cable eliminates all the risks associated with its use, be it loosening of the socket or electric shock due to poor insulation. Among the disadvantages, one can highlight the small range of action of such a device: the phone can be moved and rotated on the surface, but it cannot be torn off by more than a few millimeters.

How to use a universal charger
"Frog" is a universal battery charger. With its help you can charge absolutely any battery of a mobile phone or tablet.
Using a universal charger you can charge any smartphone battery
Every year, this charging method is used less and less due to the availability of older models of mobile phones, the increased reliability of new ones and the inconvenience of using the “Frog” itself.
The principle of operation of a universal charger is that the battery is charged directly from the network. To do this, you need to remove the battery from the phone, connect it correctly to the “Frog” antennae and connect the power by inserting the charger into the socket.
The difficulties are obvious. Opening the case of an iPhone or iPad is not that easy. Here you cannot do without special tools, the use of which at home creates a high risk of damaging the miniature circuits of the device, introducing dust into the case, or breaking it.
Video: how the Frog charger works
Alternative iPhone charging options
Technologies do not stand still, they develop, become more mobile and progressive. Chargers are not far behind: they promote the brand of alternative energy sources. They all use the energy of wind, sun, movement and even fire to turn them into electricity and power our devices.
Wind generators are small devices that, as the name suggests, are powered by wind. The movement of air causes the blades to rotate, which through simple manipulations produces energy.
Wind generators are not the most popular type of charger, as there is always a risk of falling into a calm zone
A much more well-known way to generate energy is solar panels. Scientists say the Sun will stop producing light and heat in about 4 to 6 billion years. This makes our main luminary a source of inexhaustible energy. And even though you won’t be able to charge the batteries at night, you can do this in abundance during a fine day.
In cloudy weather, the performance of the solar battery decreases
The next power source is a dynamo. What's more renewable than your own energy? The most inventive ones manage to attach a dynamo to the wheels of a bicycle, thereby freeing themselves from routine work for the sake of a fun ride.
The dynamo can also be used as a power source to charge your smartphone
These devices are on sale in almost all online stores specializing in technology and have USB ports specifically for charging phones.
The device charges slowly or does not charge at all
Follow these steps, trying again after each one.
- Check the charging cable and USB adapter for signs of damage, such as broken or bent pins. 1 Do not use damaged accessories.
- If you are charging your device from a wall outlet, check that the charging cable, USB wall adapter and wall outlet or AC power cord are connected securely, or try using a different outlet.
- Remove any debris from the charging port on the bottom of the device and firmly insert the charging cable into the device. If the charging port is damaged, your device may need servicing.
- Leave the device to charge for half an hour (if after this the device does not respond, find out what to do here).
- Force restart your device.
- On iPad models with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the top button until the device restarts.
- On iPhone 8 or later: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Side button until the Apple logo appears.
- On iPhone 7, iPhone 7 Plus, and iPod touch (7th generation): Press and hold the Side (or Top) button and the Volume Down button for at least 10 seconds until the Apple logo appears.
- On iPad with a Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold the Side (or Top) button and the Home button for at least 10 seconds until The Apple logo will not appear.
- Leave the device to charge for another half hour.
- If your device still won't turn on or charge, take the device, cable, and charging adapter to an Apple Retail Store or Apple Authorized Service Provider to have it checked. You can also contact Apple Support.
Use a powerful charger
To quickly recharge, do not try to charge the device via USB from the computer. Take the supplied power supply and connect it to an outlet. If you find a more powerful iPad adapter, charging time will be reduced.
These things will help you charge your iPhone as quickly as possible:
USB Power Adapter 12W
This unit is much more powerful than the standard one: 12 W versus 5 W. Some iPad models are equipped with it, but it will also do an excellent job of charging an iPhone. The smartphone will charge almost twice as fast.
It’s high time for iPhone Plus owners to think about purchasing a unit with the code “MD836ZM-A” ; the iPhone will spend less time at the outlet.
Lightning to USB cable 2 m
The original cable from the iPhone is usually carefully laid behind the desk and you don’t want to pull it out to charge it before going to work. Buy another original cable, but this one is two meters long.
It will be convenient to place your iPhone in the hallway or hallway for quick charging.
29W USB-C adapter
This power supply comes with the 12-inch MacBook. When you connect your iPhone, it can charge it too. Of course, charging time will be reduced even compared to charging from an iPad.
87W USB-C adapter
The most powerful portable power supply in the Apple line. They are equipped with power-hungry MacBook Pros. It will literally “pump” energy from the outlet to the connected gadget.
Lightning to USB-C cable
If you choose one of the last two blocks, you will have to acquire such a cable. They no longer have an ordinary USB port, but a new Type-C, and with this cable you can directly connect your iPhone to the latest model MacBooks.

Your IT assistant
We have all encountered a situation where the charge of a smartphone begins to decrease right before our eyes. Many will decide that it is time to change the battery, and some will think about the reasons for the rapid discharge of the battery. And the latter will be right, since knowledge about the proper use of batteries will extend the battery life for years.
The device stops charging after reaching the 80% threshold
Your iPhone may become slightly warm while charging. To extend battery life, the operating system can stop charging at 80% when the battery becomes overheated. iPhone will continue charging when its temperature decreases. Try moving your iPhone and charger to a cooler place.
iOS 13 features Optimized Battery Charging to reduce battery wear by reducing the time it takes to fully charge your iPhone. iPhone uses built-in machine learning to determine your daily charging schedule. This feature keeps your iPhone charged beyond 80% until you need it. 2 This charging method reduces battery wear and increases its service life. Optimized Charging only activates when iPhone detects that the charger will be connected for an extended period of time.
Turn on energy saving mode
In iOS 11, they even provided such a switch in the control panel, but in older versions of the system you need to go to Settings - Battery and activate the toggle switch there.
In this mode, the power of the iPhone is reduced, some processes are disabled, performance drops, but energy consumption is also reduced. This way, not only will charging be faster, but the device will also be less power-hungry throughout the day. If you don’t have time to “refuel” 90-100%, this will be useful.
A warning appears indicating that the accessory is not supported or certified
These devices may appear for several reasons: the iOS device's charging port may be dirty or damaged, the charging accessory may be faulty, damaged, or not certified by Apple, or the USB charger may not be designed to charge devices. Follow the steps below.
- Remove dirt from the charging port on the bottom of the device.
- Restart your iOS device.
- Try using a different USB cable or charger.
- Make sure your device is running the latest version of iOS.
- Contact Apple Support to arrange service.
