Charging iphone from usb port

Почему iPhone не заряжается от USB порта компьютера, повербанка или зарядка отключается через час

Если вы столкнулись с тем, что iPhone или iPad вдруг перестает заряжаться посредством USB от компьютера или повербанка, то вероятнее всего, всему виной функция «Режим ограниченного доступа USB», появившаяся в iOS 12. Данное новшество призвано защитить устройство от используемых спецслужбами хакерских техник.

Режим ограниченного доступа USB на iPhone и iPad: что это и как правильно настроить?

Получить доступ к iOS-устройству можно с помощью нескольких способов, в том числе через USB. К примеру, через коннектор Lightning взломщик может загрузить с iPhone (или iPad) все необходимые данные, взломать код доступа и разблокировать устройство.

«Режим ограниченного доступа USB», появившийся в iOS 12, отключает зарядку и передачу данных через Lightning, если со времени последней разблокировки iPhone или iPad прошло больше часа. То есть, даже заполучив устройство, злоумышленник не сможет изъять из него данные через USB, если с момента его последней разблокировки прошло достаточно времени.

Режим активирован по умолчанию, однако могут возникнуть обстоятельства, в которых вы хотели бы его отключить. К примеру, для зарядки телефона от компьютера знакомого или на время использования CarPlay в поездках на большие расстояния, когда вы в течение долгого времени не сможете разблокировать iPhone.

Как отключить / включить «Режим ограниченного доступа USB»

1. Откройте приложение «Настройки»;

2. Выберите «Face ID и код-пароль» или «Touch ID и код-пароль» в зависимости от используемого устройства;

3. Введите свой код доступа;

4. Прокрутите страницу вниз до опции «USB-аксессуары»;

5. Если с момента последней разблокировки устройства прошло больше часа, и вы не хотите разрешать передачу данных по USB, оставьте переключатель в выключенном положении;

6. Если вы хотите разрешить передачу данных по USB, передвиньте переключатель в нужное положение.

Помните, что для защиты вашего устройства переключатель лучше не трогать. Как правило, пользователи разблокируют свои iPhone каждые час-два. Если вам нужно перекинуть данные с мобильного устройства на Mac или компьютер с Windows, просто подключите его к компьютеру и введите свой код доступа. Данные будут передаваться, даже если с момента последней разблокировки прошло больше часа.

«Режим ограниченного доступа USB» доступен только на iPhone и iPad с iOS 12 и более новой версией ПО. Режим отключает устройству доступ к интерфейсу CarPlay, если с момента его последней разблокировки прошло больше часа, поэтому в данном случае пользователям придется деактивировать функцию. Из документации Apple:

«При подключении iPod Accessory Protocol (iAP) USB-аксессуаров через коннектор Lightning (таких как CarPlay, вспомогательных и зарядных устройств или съемных карт памяти) или при подключении к Mac или ПК вам может понадобиться разблокировать ваше устройство для того, чтобы оно смогло распознать аксессуар».

No Charger in the Box? Everything You Need to Know About Charging the iPhone 12 and 13

The latest Apple iPhones don’t ship with a power adapter, but they do support Apple’s wireless MagSafe charging. Whether you use a cable or not, these are the fastest ways to charge the iPhone 12 and iPhone 13.

Starting with iPhone 12, Apple no longer includes power adapters in every box as it moves to reduce package waste (and make some cash on accessories). Its newest smartphones also include support for Apple’s magnetic MagSafe charging. Here’s what you need to know about charging your iPhone 12 and iPhone 13, and what you might need to purchase.

What Comes With the iPhone 12 and iPhone 13?

Every iPhone 12 and iPhone 13 comes with a USB-C-to-Lightning cable, and that’s pretty much it. So out of the box, those who don’t currently have any Apple power adapters will need a USB-C power adapter to charge the iPhone 12 and 13.

Plus, the newer iPhones ship without EarPods, so you’ll need to supply your own headphones to listen to music and podcasts. Apple sells its own AirPods wireless earbuds, but there are plenty of alternatives that won’t break the bank, not to mention our picks for best wireless headphones and those made with runners in mind.

As Apple explained during its iPhone 12 event last year, excluding the power adapter reduces the size of the box. This means 70% more devices can fit on a shipping pallet, which means more iPhone 12 devices can ship to users. Smaller boxes also allow Apple to reduce yearly carbon emissions by 2 million metric tons, it says.

How Do I Charge the iPhone 12 and iPhone 13?

Apple has not fully transitioned the iPhone to USB-C—which typically provides faster charging speeds—or removed ports altogether, so the iPhone 12 and iPhone 13 still include the typical Lightning charge port. This means you can use an existing Lightning cable and traditional USB-A power adapter to charge both phones. With the included USB-C-to-Lightning cable, though, you can also plug your iPhone into your Mac laptop.

Additionally, the iPhone 12 and iPhone 13 are compatible with current Qi wireless charging pads. However, Apple’s main focus for charging the iPhone 12 and 13 is its built-in, fast charging MagSafe magnetic power connector.

What Is MagSafe?

For years, Apple used the term MagSafe to describe its computers’ charging cable connectors. Their magnetized tips “snapped” into the magnetized MacBook charging ports—and snapped out if disturbed so as not to bring a Mac laptop crashing to the floor, for example. They disappeared a few years ago as Apple transitioned the MacBook lineup to USB-C charging and data transfer, but returned this fall in the M1 Pro/M1 Max-based MacBooks as «MagSafe 3.»

Apple brings a similar technology to the iPhone 12 and iPhone 13 lineup in the form of a magnetized “hockey puck” disc that looks like a big Apple Watch charger and snaps to the rear of the phone. This MagSafe connector includes a USB-C cord that plugs into a power source and charges at 15W.

What’s the Fastest Way to Charge the iPhone 13?

Since iPhone 5, Apple has shipped its iPhones with a 5W USB power adapter in the box, with the exception of the iPhone 11 Pro and Pro Max, which ship with an 18W USB-C power adapter. (Apple’s iPads also ship with 10W or 12W USB or 18W or 20W USB-C power adapters, depending on the model.) So unless the iPhone 12 or iPhone 13 is your first Apple device, you probably have one of them lying around.

5 ways to charge your new iPhone 12

Apple did the unthinkable with its new iPhone 12: It stopped including a charging brick in the box. It’s supposedly better for the environment, but that’s no real consolation when your phone dies and you don’t have a compatible charging brick to resurrect it.

To make matters worse, the cable that comes with the iPhone 12 is Lightning to USB-C. In other words, the part that connects to your phone is the same as always, but the other end won’t plug into your old USB charging brick. It’s time to find a new solution, unless you feel like using the same brick and cable combination you’ve always used. If that’s the case, party on, dudes.

Anyway, Apple’s questionable business decision at least gives iPhone 12 owners an opportunity to introduce USB-C and wireless charging into their lives before one (or both) becomes a full-time standard. USB-C, in particular, isn’t going away, so it might be time to invest in a compliant charging solution.

Regular old charging bricks

The easiest, cheapest, and most straightforward solution to this problem Apple arbitrarily created is to just buy a USB-C charging brick. That is, a little piece of plastic that you plug into a power outlet with a USB-C port for that special Lightning to USB-C cable you got with your new iPhone 12.

These are not difficult to acquire, as you might imagine. Apple sells one on its online store for $19. That one will more than likely do just fine for a majority of people. There’s nothing fancy about it, but we’re talking about charging a phone, not launching a Space Shuttle. You might as well just get what works.

If you’re inclined to get a little more advanced, however, brands like Anker and Aukey produce third-party charging bricks that come with multiple ports. You just need to spend more money to get them. This one from Aukey has both USB-C and old USB ports on it for $46, making it compatible with any Lightning cable you own. For about the same price, Anker has one with two USB-C connections on it if you really want a head start on the future.

Portable chargers

For iPhone 12 owners who like to go outside every now and then (as much as we can under current circumstances), a portable charger is a must. These come in many different sizes, shapes, and capabilities. But for our purposes, we’re obviously going to focus on iPhone-friendly USB-C models.

Portable chargers measure their battery capacities in mAh, or milliampere-hour. Let’s simplify that: More mAh means more battery. Naturally, a portable charger with a big mAh measurement will last longer and likely even come with multiple charging ports. The downside is they cost more. That said, beefy portable chargers can still be had for $50 or less.

Once again, Anker and Aukey will provide decent options at inoffensive prices. Anker’s PowerCore Slim has 10,000mAh of juice along with both USB-C and regular USB ports for $30. For the same price, you can get Aukey’s 8,000mAh charger with a USB-C port and two of the older USB ports. It’s also Qi compatible for wireless charging, which we’ll discuss a little later.

Power towers

This next category is for people who are serious about cable management. This is probably way too much if all you want to do is get a reliable, available USB-C port for your iPhone 12 cable. But if you’re willing to spend some money and rearrange some cables, a USB-C power strip tower could change your life.

Yes, there are vertical power strips with normal power outlets and USB-C ports on them. They look a little ridiculous, but it’s a great way to make sure all of your devices go to the same place for easy management. This $30 one from NVEESHOX, for example, has nine outlets, three normal USB ports, and one USB-C port.

Don’t think we’re done with the familiar faces from before, either. Aukey has a $50 model with 12 power outlets, three USB ports, and two whole USB-C ports. Now that’s playing with power.

MagSafe

To coincide with the launch of the iPhone 12, Apple brought back the «MagSafe» branding that was previously used for MacBook chargers before those went to USB-C. MagSafe lives again, this time as a means of providing fast wireless charging for the iPhone 12 because AirPower never reached the finish line.

If you get an iPhone 12 and wireless charging tickles your fancy, it probably wouldn’t hurt to check out the official MagSafe charger from Apple. At $39, it’s a little more pricey than some third-party options, but it’s built specifically to magnetize to the optimal charging points on the back of the iPhone 12 for the fastest wireless charging possible — at least in theory. It’ll also work for your other wireless charging-compatible devices, so it’s not a one-trick pony.

Apple’s also selling a $49 MagSafe-compliant case for the iPhone 12 if you really need to burn some cash.

Third-party wireless chargers

Don’t be fooled by Apple’s MagSafe-heavy branding for the iPhone 12: Any Qi-based wireless charger will work. In other words, if you’ve been using a wireless charging pad for a while already, it’s going to work with the iPhone 12. It just might not charge as quickly as the MagSafe mat.

Still, some people live their lives at a deliberate pace. They don’t need to go from zero to 100 in a pinch, and they certainly don’t need to overpay for the privilege of doing so. Our friends at PCMag have an excellent roundup of great third-party wireless chargers, many of which are significantly less expensive than MagSafe.

For instance, Anker sells a basic wireless charging mat for $11.95. That’s about as much as a particularly excessive combo at Taco Bell and probably a lot less bad for you. This $20 option from Mophie is also appealing for those with tight budgets and a need to just set the phone down for a while.
