At the last event Apple introduced the new iPad Pro with USB-C port instead of the old Lightning port. You only need to connect the new iPad Pro to the iPhone via the USB-C to Lightning cord, the phone will be charged. But it turned out that Android representatives, typically Galaxy Note9 had this function… for a while and is much simpler.

No need to buy extra accessories

For iPhone, you must buy a $ 20 USB-C to Lightning cable from Apple or buy it for a little bit less. However, with the Google Pixel 3 or the recent Galaxy Note series, you don’t have to buy anything else. Google offers a USB-C two-head cable with the free device. You can use this cable to plug directly between two devices with Type-C ports to “rob the rich” give to “the poor”

What happens when connecting two phones using a USB-C port?

You will not be able to create a eternal engine by charging over and over.

Instead, you will have to select one side host and “receive” (client) each time connecting the two devices at the notification popup.

After opening the USB option message, you can “receive” or “battery”, transfer photos or exchange data easily between two Nexus together.

What about Android (Type-C) with iPhone (Lightning)?

Not that complicated, if there is no USB-C to Lightning cable available, you simply plug the OTG switch port, connecting to the iPhone’s USB-A to Lightning cable. (OTG port is available in the box attached to the device)

transfering data when changing a new phone becomes easier than ever. Photos, music, call history or messages are synchronized easily.

You can get your Note 9 to help your girlfriend when her iPhone runs out of battery, copy photos from iPhone faster than AirDrop and more.

Note 8 (Type-C) connects Note 9 (Type-C) via OTG. Who will benefit?

The Galaxy Note8 battery capacity of 3300 mAh and Note9 is 4000 mAh. Do you think when connecting these two super products, the battery will pass from the high side to the low side?

Not really, different from Nexus 2 when using USB-C 2-headed cable. In this method the default of the OTG plug will be the host – the power supply, the other side will be the client – receive the power.

Current strength is quite safe

The charging current measured by Ampere software is 340mA. This is the number when Note8 battery is nearly full. According to the writer’s experience, if charging from 0%, the current will be higher, maybe up to the standard 600mA level when charging from a laptop to the phone.

Of course, the device does not recognize the 2A fast charger as if using a socket, if you want to quickly, you should turn off the power or leave the phone in flight mode.

Wait, what about microUSB to USB-C? Can my Note4 charge each other?

The answer is yes, Samsung has been supporting OTG for a long time. Maybe… even Galaxy S2 had it.

Not all models are supported. The mid-range Android series like Xiaomi or Huawei rarely gets the OTG function enabled by the manufacturer, unless the user “root” the device and install Rom from outside.

So you already know how to charge Note9 for iPhone. OTG port also helps us do a lot of things like connecting with mouse keys or gaming handles, but that’s another topic.

Well, the cool and new features that Apple announced are actually not as new as you see. Android manufacturers, typically Samsung, have had them for a long time. Recent features such as 512GB of memory, 2 SIMs, a large 6.5-inch OLED display … are all things Samsung has done for a few years before Apple. And now it is the battery charging feature for this phone.
