iPhone 12 USB 2.0 Speed - Apple iPhone 12 Guides, News, & Discussion

Hello users,
I bought the iPhone 12 Pro and tested the USB speed. The iPhone 12 Pro only supports USB 2.0 speed. USB 2.0 = up to 480 MBit/s = up to 60 MB/s
The PC (my PCIe card has USB-C - USB 3.2 Gen 2 connectors) is always the USB host and used a Lightning to USB-C cable for the iPhone 12 Pro. I copied files from the PC to the devices.
Test file:
1. 604 MB GiB (1x mp4 file)
2. 3.94 GB (15 x mp4 files)
Code:
iPhone 12 Pro
1.
20 s = 30.2 MB/s
2.
02 min 20 s (140 s) = 28.8 MB/s
Here for comparison with other smartphones.
Code:
Xiaomi Redmi Note 9 Pro
1.
15s = 42.1 MB/s
2.
01 min 58 s = 35.8 MB/s
Code:
OnePlus 7 Pro.
The OnePlus 7 Pro is the only smartphone I have supported the USB 3 speed.
1.
2s = 282.8 MB/s
2.
16 s = 258 MB/s

Z3 Dual Wi-Fi - only 72Mbps

My laptop connects with 300Mpbs. But my Xperia connects to the same access point only with 72Mbps.
Mine too.
My original Z did that as well, but my wife's G2, and my dads knock off Chinese phone connect at 150...
Sent from my Nexus 7 using XDA Free mobile app
The Snapdragon Chipset only has one antenna.
Most Phones
N Mode
1 antenna in 20Mhz mode = 72 Mbps Link
1 antenna in 40Mhz mode = 144 Mbps Link (Aka 150)
AC Mode
1 antenna = 433 Mbps Link (I get this as I have an AC router: Netgear R8000)(Z3 gets around 240 Mbps peak transfer speed)
Most Laptops
N Mode
2 antenna in 20Mhz mode = 144 Mbps Link (aka 150)
2 antenna in 40Mhz mode = 288 Mbps Link (aka 300)
AC Mode
2 antenna = 866 Mbps Link (My laptop with Intel 7260AC adapter gets this link)(Gets around 320-400 Mbps peak transfer speed)
Reason for single antenna is to save power. The Snapdragon 810 Chipset will have a 2x2 antenna (aka 2 antenna).
40 Mhz for 2.4Ghz Band is generally not preferred in residential areas with lots of WiFi users/congestion as it uses more channels causing interference and may actually lower your effective range.
This is why older Apple products and Intel adapters at one point did not allow 40Mhz mode for 2.4 Ghz. Modern routers automatically drop to 20Mhz if they are conflicting with your neighbors and many don't let you force 40Mhz mode only supporting auto switching based on interference or the other option being 20Mhz mode, this applies to all Intel adapters as well.
Also these are link speeds not the actual transfer speeds, in N mode my laptop drops from 300 link speed to 240 or 144 due to many neighbors having WiFi. That's why I use 5Ghz N or AC as very few people have this.
Remember actual throughput will always be less than the link speed due to overheads, generally around 60-70% of the link speed with good range/signal.
The best transfer speed on the Z3 at 433 Link speed for me is around 240 MBps.
I still can't understand
1. Why my laptop use 2 antenna in 40Mhz mode = 288 Mbps Link (aka 300) and in the same time my Z3 use 1 antenna in 20Mhz mode = 72 Mbps Link with the same wi-fi access point.
2. And why my Z3 don't use 1 antenna in 40Mhz mode = 144 Mbps Link (Aka 150).
Yeah I get that too, Sony probably did that to avoid interference. Even my dads M8, sisters GS4, mom's iPhone 6 does that.
20Mhz means Less interference so longer range and battery life due to less packet resends. I doubt it would impact you much if at all. If you really want more bandwidth switch to 5Ghz mode though range will be less unless your on 5Ghz AC.
In N mode even my laptop drops link rate from 300 to around 270-144 most of the time because neighbors also use WiFi obviously.

Anyone already using the new USB Type C Pendisks?

So, anyone already using the new USB Type C Pendisks? It's a great backup solution if the Nexus 6P supports them.
This is promising! Any usb c pendisk should work.
From: http://www.computerworld.com/articl...m-lexar-one-from-sandisk-go-head-to-head.html
"The Type-C USB port is expected to be available on 12% of smartphones in 2016, according to research firm IDC. So, I also tested the thumbdrive by downloading the 1.81GB .mpeg file to a Nexus 6P smartphone, which uses a Qualcomm Snapdragon 810 v2.1 processor.
I was surprised at how slow the transfer was; it took the Lexar 4 minutes and 47 seconds to move Star Wars onto the smartphone. The transfer speeds varied between 4.4MB/s to 7.8MB/s, considerably slower than USB 3.1's 10Gbps advertised speed. The SanDisk took 4.49 seconds to upload the movie and ranged from 4.3MB/s to 10.3MB/s transfer speeds."

He'd probably be less surprised if he did his homework and realized that the USB-C on Nexus6p is advertised to transfer at USB 2.0 speeds.
Yes, but that was the Lexar pen. The Sandisk one transfered the file in 4.49 secs. Forget it. 4 minutes and 49 secs.
I currently own a Kingston DataTraveler microDuo 3C (64Gb) and couldn't be happier with it. I'm not sure about the phone transfer speeds but on a PC, it scores 20MB/s writing speed. I could watch a 2Gb 1080p .mkv movie I had stored there with my good Chromecast with 0 lag or stuttering, really recommended!
What is pendisk? Thumb drive?
I was wondering what "pendisk" was also. Lol
I'm using the Kingston dt duo
I am using a adapter pretty cheap. Well its fast like ? check out those pics. Working real good ?
It provides and give painless to transfer content between new-generation tablets and phones1, and PC and Mac computers.
