iPhone 14 Pro: Huge new camera sensor, same slow Lightning cable data transfer

So iPhone 14 Pro is impressive. Truly Impressive – The 48MP sensor on the device’s main camera lens allows capturing the largest and most detailed photos yet on an iPhone. It can also capture stunning 4K video with optical zoom quality.

And Apple definitely wants you to shoot professional-quality content with the iPhone Pro camera. In fact, The company did an entire advertising campaign out of it.

But bigger sensors also mean bigger coils. how much bigger? Well, 48MP is uncompressed ProRAW Image size will be between 48MB – 60MB, and when using HEVC codec, about 400MB per minute of 4K video.

For those of us who are going crazy and want to use the new sensor’s 48MP ProRAW capabilities, this is way too much file space if you start out recording five or 10 minute 4K clips or take a few hundred photos in one session. You’ll need to empty your device onto your Mac or PC, or maybe your iPad, where you can make desktop-style photo edits.

If you’ve ever had to transfer video from your iPhone to your Mac using a Lightning cable, you probably know how slow it can be. First, the Photos app has to sync and index file lists and thumbnails, which takes some time. Then you have to perform an import procedure.

How slow is lightning? Well, because it’s a file USB 2.0 Instead of USB 3.2 or 4.0 technology, the maximum transfer rate is 480 megabytes per second, or roughly 60 megabytes per second (MB/sec).

This means that if you have 100 ProRAW photos that you need to transfer on your iPhone 14 Pro, it can take more than a second to transfer each photo, or over a minute and a half for 100 exposures, assuming optimal transfer rates. Realistically, it’s probably more due to indexing.

A five-minute 4K video has a size of about 2000MB or 2GB. At this rate, it can take up to 13 minutes to transfer that much data over a Lightning cable. Maybe longer.

We don’t have the full specs on whether or not the iPhone 14 has been upgraded to USB 3 – some newer iPads have a USB 3.2 connection, but those use USB-C connectors.

How fast is USB 3.2? The theoretical limit for generation 1 is 4.8 gigabits per second or 600 megabytes per second (MB/sec). USB 3.2 Gen 2 is 10 Gbps, and USB 3.2 Gen 2×2 is 20 Gbps. And USB 4 / Thunderbolt 3? 40 Gbps or 5,000 Mbps, more than 80 times more than USB 2.0 transfer rates.

(Yes, we know, it’s confusing. do not ask Ed Pot To technically edit your post before having your first coffee.)

Now, Apple may have upgraded the Lightning connector this year — no one has examined the iPhone 14 Pro closely yet. But it is also possible that it did not happen because of the European Union Apple will be forced to use USB-C next yearSo, Apple may wait to make more drastic changes to its chipsets and connectors. Or Apple may decide to forgo cables entirely.

It is definitely possible AirDrop Photos on Your Mac. iPhone 13 Pro Max had a file The maximum Wi-Fi transfer rate is about 1200Mbps, using an 80MHz channel on the 5GHz band with spatial streams. This is an improvement over USB 2.0 – about 2.5 times faster.

But it’s only a quarter as fast as USB 3.2 Gen 1, let alone a USB 4 / Thunderbolt cable. With Wi-Fi 6, the maximum data rate for 802.11ax is much higher, but only on devices with 160MHz channels using four or more spatial streams. MacBook Pro It can only support spatial streams Like the iPhone, so AirDrop is up to 1200Mbps.

I don’t expect the iPhone 14’s comms stack to be much better than its predecessor, even with a native wireless chipset, if that’s actually what they ended up using this year.

Remember that while reading from iPhone flash memory is very fast and AirDrop is also fast, you are also limited by the writing speeds of the destination computer you are transferring files to. However, this is not an issue with content creation level systems; in the end MacBook Pro M1 MaxOn the internal SSD, you can get write speeds of up to 7.5GB/s.

We haven’t even come close to saturating that with Lightning’s USB 2.0 speeds of 60MB/s.

But there is still a good built-in toolkit currently out there for wirelessly dragging and dropping bundled photos and videos from your iPhone to your Mac (you can’t use AirDrop on a PC); Apple makes you use iCloud.

This is not what you want as a professional content creator; You want the fastest direct connection possible. There are third-party tools for this, but they are not always reliable.

I think there is always next year.
