IPhone 8 may have included a 10w charger with USB Type-C

Still rumors about IPhone 8, the new generation Apple smartphone that has the difficult task of celebrating worthily the ten years of the revolutionary brand. According to the analyst of KGI Securities Ming-Chi Kuo, known in the panorama of rumors about Apple products, the device will have a charger compatible with the standard USB Type-C Power delivery which ensures extremely short recharge times. However, the charging port of the device will still be Lightning, and not USB-C.

 

It echoes KGI Securities the research of Blayne Curtis, Barclays analyst, according to which the loader will reach a maximum power of 10w; It is worth noting that the current IPhone 7 charger is 5w, while it rises to 12w on IPad. Both still take advantage of the old USB type-A ports, but the USB type-C is not an absolute novelty: it is in fact present in the new MacBook chargers, which reach the power of 29W.

 

Recall that, according to previous rumors, the battery of the IPhone 8 could be two cells in the shape of “L”; Your device may also support wireless charging. It remains to be understood how Apple will decide to proceed with the cables in the package: a Lightning/USB Type-C cable is the most desirable option, perhaps with an adapter from USB-C to USB-A to ensure greater compatibility.

Introducing the iphone x: Why the day for Apple and US is so important

Much, very much is already known to iphone x aka iphone 8. So the Apple event tonight is getting boring? Not. The company provides a number of choices, in the following three examples. How will it end?

Still last week, our information after some accessories manufacturers did not dare to print the packaging for the finished (!) new iphone cases. Reason: You did not know the name of the coming Apple smartphone. iphone 8? No, probably iphone X. Apple was able to keep this autumn an important fact secret until just before the event. Overall, however, a lot is known about the new model, see the summary in the video:

And this information makes it clear: Apple packs it back in. Relies on new, must separate itself from proven. It is probable whether this will be the acceptance of us (the customer). But it depends on how well the Apple engineers did their job in the last few months. Three examples of turnouts:

1. A lot of OLED for iphone

Yes, the iphone 7 is chic. But anyone who had the latest Samsung devices in their hands can no longer be impressed by the Apple device. Large display, bright colors – The iphone cannot keep up with it, although it also has a very good display. The new iphone now gets a comparably huge display (5.8 inches) that shows deep black and radiant colors – thanks to OLED technology.

Will the interested parties be prepared to put a few hundreds more on the table?

2. Bye, bye, lightning? A new port

Lightning quickly found a broad acceptance in the Apple warehouse after a little whining about the 30-pin connection. Will Apple actually use the iphone x to give up the exclusive port in favor of USB C? It sounds incredible, but should come like this. And then there is a wireless charging option…

With this turnout position, sooner or later any iphone lover will be confronted. “Juhuu” or “aargghhh”? This depends on which and how many accessory products are at home.

3. Face ID: Does face recognition work right away?

Enter code-how annoying is that?! For many, the fingerprint sensor only means to protect the smartphone content with a code.

Will the new technology, face detection, work just as quickly and reliably as Touch ID?

Will it even be safer – or let yourself be “hacked” with a photo?

Conclusion: On Tuesday evening, Apple sets some course for the future, the three innovations are more significant than “again a faster processor”, “Greater water protection”, “better camera” and the like. Tomorrow night it will be exciting.

We get a first look at the new devices in the livestream and in the live ticker to the Apple event from 19:00 am. Furthermore, our colleague Ben is on the spot and will get an impression of the novelties for Giga. We’re excited.

 

USB Type-C and 3.1

What you need to know

Standard, transfer speed, type of connector, power supply and compatibility: so many factors that vary without really knowing what these changes are due to. At a time when the Type-C tries to impose on all our devices (smartphones, motherboards, laptop), let’s make the point and check what it really brings.

 

Presented for the first time around 2013, the Type-C connector can be seen as a reaction of the USB-IF, the consortium in charge of the development of the USB, following the output of the Lightning connector of Apple in 2012 which was the first compact reversible connector. What to put an end to the situation that we all know with a chance on two to crash (or more if affinities).

 

However, while Apple has hardly developed its connector that remains dedicated to the IPhone, IPad and IPod (mobile devices for which it is used primarily as a connector for charging), the USB-IF wanted to integrate all the forces of the USB, starting with the possibility to benefit from gargantuan bandwidth and innumerable devices (via a simple adapter). As we recall in passing that any innovator that was the Lightning connector of Apple, this one is content with 8 pins (vs. 24 for USB Type-c), which limits its fields of application and therefore it is confined to mobile devices, Apple preferring even the type-C for its MacBook.

And if the type-C was a little late, it seems to be definitely gone since almost all the smartphones, all the laptops and a huge majority of motherboards are now launched with a C-type. But what is this format? What does it bring with respect to other connectors? and is it necessary to take advantage of the 10 Gb/s of the USB 3.1?

 

No less than 10 connectors

 

The USB is no less than 10 connectors in all and for everything. So let’s start by clarifying this point. The classic connector is type-A, but this one is split between the classic type-a, with 4 strands, and the type-a superspeed, which has 8 strands and will therefore be able to withstand the flow rates of the USB 3.0 and 3.1. This connector is usually differentiated by a blue plastic insert, but some builders opt for a different color in order to better tune in with their design.

 

Then comes Type-B, which is more square in shape and is used to connect large devices such as printers or external HDD boxes (Format 3.5 ”). Again, there is the classic version, limited to 480 Mb/s, and SuperSpeed version.

 

These connectors are quite wide, so the USB-IF had introduced mini connectors, simply called mini-A and Mini-B. The first was somewhat unused and was neglected for the benefit of the second which was found on many small devices such as memory card readers or external HDD boxes (Format 2.5 ”). To go even further, the micro-A and micro-B were then discovered. Same verdict for version A, little used, while version B is simply the one that has been found for years on our smartphones (the micro-USB as it is called frequently). Once is not custom, this connector being limited to USB 2.0 speeds, a superspeed version has emerged, doubling the number of pins to the detriment of clutter and solidity. This Micro-B SuperSpeed is used for card readers or USB 3.0 HDD cases.

 

TYPE-C, the innovative

 

The last of the family is precisely the Type-C. Its name breaks radically with the rest of the line, and for cause it is reversible. That is, while all other connectors must be plugged in a particular direction, with a non-symmetrical plug as a deceiving, this time the Type-C can be inserted in both directions. This is made possible by a symmetrical socket on the one hand and by the presence of a contact used to detect the orientation of the cable.

 

The USB-IF has also tried to correct the relative fragility of the Micro-B with the Type-C, which prevents the cases where the connector is folded into the receptacle.

Incidentally, the C-Type marks a break with the other USB connectors in the sense that it serves both on the host and on the client. Understand that the cables with a type-C connector at each end will indeed be a reality, whereas previously, it was the type-a only that were present on the hosts, while one of the other 7 connectors was found on the devices. The Type-A should still remain for a long time, if only to keep the compatibility that is expensive to the USB, but nothing says that it will not disappear eventually. In this eventuality, the C-type being a real USB port, a simple adapter will transform it into type-A and connect old peripherals.

USB 3.1 GEN1 and GEN2

Back in 2010, the time or USB 3.0 was introduced on motherboards. At this time, the USB 2.0 and its 480 Mb/s were insufficient, so the new standard promises 5 Gb/s. In practice, throughputs revolve around 3.2 Gb/s (400 MB/s) but the same problem was encountered in USB2.0 (30 to 35 MB/s Instead of the theoretical 50)

In 2013, the USB-IF consortium goes further and pushes to 10 Gb/s. At this point, there is a reference to a standard called USB 3.1. But of course, marketing got involved, and instead of maintaining this clear split, the USB 3.0 became USB 3 Gen1, as opposed to the USB 3.1 Gen2 which is Bel is the only one capable of providing 10 Gb/s. All this so that manufacturers can display a USB 3.1 logo on products that have not changed much since their USB 3.0 certification (the only difference will only be few people).

If you are looking for 10 Gb/s, the only USB 3.1 criterion will not necessarily be sufficient, so you will have to delve in more detail. At about the same time as the USB 3.1, the USB-IF introduced a concept of reversible connector that finally called USB Type-C. Amalgam was quickly made between the two standards, but they are indeed independent. In fact, the Type-C connectors on smartphones are generally limited to USB 2.0 connectivity.

USB POWER Delivery, an independent standard

Power Delivery Table

In addition to the standard that defines the speed of the USB, we find in parallel the standard known as USB power delivery, which determines the power that each connector can deliver. For example, a conventional USB port will deliver 500ma in 5v, or 2, 5w. But another, stronger, can climb to 900mA or 4, 5w. For the battery recharge, which is therefore transferring data, we can increase the power delivered and thus climb to 5a, or 25W. This point is important because ports and cables capable of delivering maximum power will ensure faster recharge of your devices (smartphone, mouse, headphones, gamepad, etc.) while this can also allow to be satisfied with a single cable for some devices (keyboards, HDD players).

To spice it up, the Type-C connector opens a new overhaul of its own Power delivery. Base, this connector can provide 1.5 A or 3 a always in 5v. Either 7.5 W or 15w which, in both cases, is already much more than the majority of Type-A connectors. Under certain conditions, it will be possible to climb to 5a and 20v, the Bagatelle of 100 watts of power. Enough to feed more greedy elements, such as laptops or screens. This gives rise to many combinations between the type of connector, its standard and the power delivered. It will be noted in the passage that if a Type-C connector can in some cases deliver 100 W, it may just as well be limited to 7.5 w while a type-a will be able to provide more than 7.5 w, proving that the C-type is not necessarily synonymous with large power.

Alternative MODES

With USB 3.1, the USB-IF has implemented an additional mode of communication for direct connection between device and host via alternative data protocols. This is the alternate mode. Four types are originally planned, but manufacturers can also incorporate their own proprietary technology, as this is based on the recalibrated wiring on the fly. Thus, the USB can be transformed into DisplayPort, MHL, HDMI or Thunderbolt (the latter including DisplayPort and potentially other connectors).

Of course, it is possible to connect screens or other devices to conventional 3.0 ports, but this required either devices intended to operate via a USB signal or active adapters.

What about the OTG?

For those who do not know what it is, the USB OTG (On-the-Go) refers to the ability of some mobile devices (smartphones and tablets primarily) to operate compatible USB sticks. The key as the terminal must therefore be compatible with this standard. But until then, smartphones were equipped with USB micro-B (or micro-USB) connectors while PCs used Type-A connectors. In fact, the few micro-B keys were specifically intended for mobile devices and were OTG compatible. With the Type-C being a universal connector, it will not be the same here. It will therefore be necessary to check the compatibility OTG not only on the side of your device (and of course, very few seem compatible at the moment), but also that of the key you want to accept.

Dangerous cables!

Here we will pass the details on the power supply of the USB, but also know that there are 3 separate circuits of monitoring, each is intended to ensure that the right power is assigned to the right type of device, both smartphones (and their fast reloads) as well as standard and older devices that are not compatible with USB 3.1 and its power standards. Manufacturers must therefore integrate a small piece of PCB at the level of each connector that incorporates a power control circuit. However, whether it is to save money or simply design error, some manufacturers do not incorporate the necessary protections. The consequence is immediate: If you connect a type-C device to a type-a connector via a type-a-to type-C cable, if it is not compliant, the unit may pull more power than the port is capable of delivering. Therefore, there are potential damage to the Type-A connector which can, in the worst case, damage the controller (and therefore the motherboard or charger) or even cause a fire. And do not believe that this kind of problem is found only in low-cost brands since OnePlus was caught red-handed in the bag with the cable of the OnePlus 2 (that of the OnePlus 3 fixes the problem). But rest assured, this only applies to type-A to type-C cables, and it will suffice to ensure that they incorporate a 56kohms resistance to avoid any inconvenience. If this point is not specified, go your way.

Also pay ATTENTION to the transfer speeds

As we said, there was a giant amalgam between USB 3.1, 10 Gb/s, and the USB Power delivery which makes even the builders tangle (or try to drown the fish). Many are therefore those who will display a so-called USB 3.1 certification simply because their products support a powerful power supply without the flow rates being at the rendezvous. Same thing for the alternate mode: This is only available on USB 3.1 ports (GEN1 or GEN2) but some are confusing between USB 3.0 and USB 3.1 Gen1 to display false USB 3.1 Gen1 (which go unnoticed in most cases). But in the world of laptops, motherboards and desktop PCs, it’s fortunately very rare (and there’s only one that could be awkward).

Therefore, be sure to check the presence of a specific reference to the flow rate (5 GB/s or 10 Gb/s), of the standard (3.0, 3 Gen1 or 3 Gen2) or the power delivered (from 2.5 to 100 W, or from 500ma to 5a), regardless of the type of product under consideration (type-A or type-C).
