Despite being similar, USB-C and Lightning are not the same. They are among the most popular charging cables on the market, especially when it comes to mobile devices.
The most significant difference between the two cable types is that Lightning is a proprietary connector used on iPhones and other Apple devices. Some other key factors set USB-C and Lightning apart.
Even when most of the consumer electronics industry has consolidated around USB-C, Apple continued to use its proprietary Lightning connector on the iPhone and a handful of accessories like the ever-popular AirPods line for several years. Luckily, that finally changed in 2023 with the release of the iPhone 15 series. But you may wonder, what are the practical differences — from charging power to data transfer speeds between the two ports? So in this article, let’s take a deep dive into the differences separating USB-C vs Lightning and why Apple has made the switch.
Connectors for USB-C Cable and Lightning Cable
USB-C Cable
- Introduced in 2014.
- Joined USB-A and USB-B as popular connectors.
- Used for connection, communication, and power supply.
- Compatible with the latest models.
Lightning Cable
- Introduced in 2012.
- Replaced Apple's 30-pin dock connector in Apple iPhone 5.
- Used for connection, communication, and power supply.
- Discontinued after the launch of the iPhone 15 Series.
USB-C and Lightning (not to be confused with Thunderbolt) are protocols used for connection, communication, and power supply. Although both cable types are primarily for charging devices like smartphones and tablets, you can also use them for digital transfer tasks such as uploading or downloading movies, music, photos, and more.
USB-C is considered by many to be the current standard for charging and transferring data. However, every iPhone and iPad since September 2012 has come with a Lightning cable. The exception is the iPad Pro, which adopted USB-C starting with the 3rd generation models in 2018). Lightning has remained on the iPhone since 2012, while other manufacturers have used several types of USB ports before (mostly) settling on USB-C.
Setting aside Apple exclusivity, USB-C is superior to Lightning in just about every way having the benefit of being a new connector coming out years after Lightning.
Data Transfer Rates: USB-C Is Significantly Faster
USB-C is capable of supporting USB4, the latest and fastest USB specification. As a result, USB-C cables can transfer speeds up to 40Gbps. By comparison, Lightning cables are much slower and transfer data at USB 2.0 rates of 480Mbps.
Complicating matters is that Apple doesn't release all specifications for its proprietary technology, so it's unclear what Lightning's actual maximum transfer speed is. That said, Apple hasn't released a protocol update since Lightning's release, meaning its functionality has changed little since 2012. There are, of course, pluses to this. You can use a cable from 2012, and it's still compatible with new iPhones.
As the numbers indicate, USB-C has a massive speed advantage over Lightning. That said, this advantage isn't as significant as it seems, considering most people now transfer data wirelessly from their phones and other devices instead of using a cable.
USB-C vs Lightning: Which cable transfers data the fastest?
Both USB-C and Lightning allow data transfer to and from a computer but at vastly different speeds. Even within the same connector, the exact speed often varies from one device to the next. For example, we know that the Lightning connector is capable of USB 3.0 speeds since it was included in previous generations of the iPad Pro. However, Lightning on the iPhone was always restricted to USB 2.0 speeds.
This meant that the iPhone’s Lightning connector could sometimes be slow enough to bottleneck professional workflows on the iPhone. If you shoot 4K HDR video in Apple’s ProRes video codec, every minute of footage outputs around 6GB of video data. Transferring longer clips at USB 2.0 speeds could easily take an hour or longer. And considering that Apple sold Lightning-equipped devices in capacities as high as 1TB, filling it all up in one go could take a while.
The last iPhones to include Lightning were limited to slow USB 2.0 transfer speeds.
For some context, USB 2.0 offers a maximum transfer rate of just 480Mbps, while USB 3 increases that to a whopping 10Gbps.
With the release of the iPhone 15 series and the introduction of USB-C, Apple has once again drawn a line in the sand. The base iPhone 15 continues to keep USB 2 transfer speeds and only the Pro models get USB 3.0. The latter will also support display-out and transfer speeds of up to 10Gb/s.
However, the USB-C connector also supports the latest USB4 specification, which takes transfer speeds up another notch to 40Gbps. Once again, most devices don’t support the fastest speeds. Flagship Android smartphones like the Samsung Galaxy S23 Ultra and Pixel 7 Pro offer USB 3 speeds. However, budget devices like the Galaxy A54 are often limited to USB 2.0 speeds.
Compatibility: Lightning Only Works With Apple Devices
Lightning was a replacement port for Apple's old 30-pin connector first introduced with the iPod back in 2001. As a replacement, it was better in every way: It was smaller, it could be inserted either way, and it moved data and power more quickly than the 30-pin connector. At the time, Apple said it was going to be their standard for the next 10 years. It's gone well beyond that.
Apple has used the Lightning connector in various products, including keyboards, trackpads, mice, AirPods and more.
Apple has begun to transition away from Lightning to USB-C in some products as it has more capabilities than Lightning (pressure from the EU has also played a part). Most iPads now use USB-C (only the 9th generation iPad remains using Lightning), and all Mac laptops use (or can use) USB-C to charge and carry data.
Fast Charging: USB-C Supports Higher Wattage and Current
Fast charging requires a USB-C to Lightning cable and a 20W or higher power adapter.
USB-C offers a higher power delivery rate than Lightning and delivers a faster charge under the same voltage. Whereas Lightning supports a maximum current of 2.4A, USB-C carries 3A with support for up to 5A. This distinction makes USB-C much better for fast charging, as it supports the USB Power Delivery fast-charging standard.
Standard Lightning cables don’t support fast charging, so Apple includes a USB-C to Lightning Cable with most products. Combined with a 20W or higher power adapter, you can fast-charge an iPhone up to 50% battery in about 30 minutes.
Between USB-C and Lightning, only the former can supply power to larger electronics like laptops. USB Power Delivery (USB-PD) was recently revised to support 240W of charging power. But even before that, devices could pull up to 100W with a compatible USB-C cable. That’s a lot higher than the 25W Apple pushes via the Lightning connector.
Moreover, not all Android smartphones rely on the basic Power Delivery standard. A handful of manufacturers also offer their proprietary charging protocols using the USB-C connector. Examples include OPPO’s SuperVOOC and Xiaomi’s HyperCharge technologies. Both protocols already support charging power above 100W, albeit only on a select few models. Still, with that much power, you can charge up a smartphone from empty to full within 20 minutes.
Lightning doesn't charge as fast as USB-C, but that could be an intentional limitation.
The latest iPhone 15 series still doesn’t exceed 25-27W, at least according to Apple’s spec sheet and tests conducted on previous-gen iPhone models.
Apple’s decision to limit charging power to 25W on the iPhone might be a conservative one to limit heat output in such a small form factor. That said, the company opted to use USB-C on the MacBook Pro and Air series instead – with support for up to 100W charging power. Similarly, the iPad Air and Pro have also moved past Lightning and can charge at speeds above 25W, but not as high as 100W or even 65W.
Durability: USB-C Cables May Last Longer, but Lightning Offers a More Stable Physical Connection
In terms of ease of use and durability, USB-C and Lightning are closely aligned. Both connections have reversible ends, making them easier to plug into your devices. They also include chips to help guarantee compatibility and control power supply for stabilized current and data transfers.
Anecdotally, there's considerable debate over which cable offers better durability. Some people claim that Lightning cables break more easily, while others argue that Lightning's connecting tabs fit better in their respective ports and are less prone to loose connections than USB-C. That said, much of this comes down to personal preference.
The best thing you can do to increase the longevity of either cable is to purchase one from a trusted manufacturer and take good care of both the cable and your device's condition.
Final Verdict: USB-C is the Better Connector
Durability debates aside, USB-C is superior to Lightning in just about every way. It offers wider compatibility, faster data transfer rates, and increased power delivery for better fast charging.
With pressure mounting from European regulators for the mobile industry to adopt a universal standard, Apple appears to not have much say in the matter.
Virtually every single Android smartphone on the market now uses USB-C for data transfer and charging. The Lightning connector, meanwhile, was of the iPhone series between 2012 and 2022, even as other Apple devices migrated to USB-C. The company didn’t ever disclose the reasoning behind this decision. That said, some speculated that it could have been to maintain backwards compatibility with several years’ worth of Apple and third-party iPhone accessories.
Lightning also allowed Apple to earn licensing fees through the Made For iPhone/iPad (MFi) program. Third-party accessory makers also have to abide by certain rules, giving Apple much more control over the Lightning ecosystem. On the other hand, manufacturers can implement both USB-C and Power Delivery without paying any licensing fees.
The Lightning connector is not long for this world.
Still, Lightning’s time came to an end when EU policymakers unanimously agreed to mandate USB-C on all new smartphones and tablets sold in the region by 2024. And that is why, the Lightning connector no longer exists on the latest iPhone and beyond.

FAQ
What is a USB C-to Lightning cable?
Answer: A USB-C to Lightning cable has a Lightning connector on one end, with a USB-C connector on the other end instead of a standard USB-A connector. With a USB-C to Lightning cable, you can charge and sync your iOS devices.
Why do charging cables stop working?
Answer: The cable takes a lot of stress over time, and that's a likely culprit when your charger stops working. It's possible for a charging cable's copper wiring to be damaged, causing the charger to stop working or work intermittently. Sometimes, however, the charger is the problem, not the cable. To fix a broken charger, test the wall socket and look for damage to the device's power port.
How long can a USB-C cable be?
Answer: Different USB cable types have different maximum lengths. USB 2.0 cables can extend to about 98 feet (30 meters). USB 3.0 and 3.1 cables can extend only to about 59 feet (18 meters). Your extension cables can only be as long as the original cable.
