- Bluetooth 5.3 has a maximum transmission speed of 50 Mbps, compared to Bluetooth 1.2’s 1 Mbps.
- Bluetooth 5.3 has lower power requirements and better compatibility with newer devices, while Bluetooth 1.2 is more backward compatible but lacks the performance and features of the newer protocol.
What’s the real difference between Bluetooth 5.3 and Bluetooth 1.2? Wireless connectivity evolves alongside the many leaps in computing. However, it can be tricky to spot the differences if you aren’t in the know about today’s technologies. While you could spend time looking at a slew of online articles that are a bit nebulous, this guide will be cutting straight to the point.
If you’ve been curious about how your wireless devices are connected to your smartphone and laptop, you’re in the right place. This guide will take a closer look at version 1.2 and version 5.3 of the Bluetooth protocol and tell you everything you need to know about one of the preeminent wireless protocols today.

As you can likely see, Bluetooth 5.3 is a vast improvement over Bluetooth 1.2 That is to be expected when analyzing technologies that have almost two decades of development between them.
Bluetooth 5.3 vs. Bluetooth 1.2: What’s the Difference?
When it comes to overall performance, there really is no comparison. Bluetooth 5.3 trounces 1.2 in every conceivable way. It has better overall performance, is capable of wireless high-definition audio, and presents a more stable configuration for compatible wireless devices.
This does have some drawbacks, however. Most devices on the market are going to be compatible with Bluetooth 1.2 peripherals, even though the standard hasn’t been in active use since sometime in the early 2000s. If you want to use Bluetooth 5.3, you’re going to need a device that was made in 2022 or later.
As such, this can greatly limit the overall selection, especially if you’re using an older phone or laptop. However, if you don’t mind upgrading, there are only major benefits to utilizing Bluetooth 5.3 for connecting devices like tablets, smartphones, and laptops to wireless speakers and other accessories.
The largest difference seen between the two protocols is the overall transmission distance. Bluetooth 1.2 does have the benefit of using EDR, which increases the broadcast range and speed of any transmission. However, you’re looking at a distance measured in dozens of feet during ideal conditions.
- Advanced Bluetooth 5.3 technology
- 13mm drivers that boost the bass
- Dual-ear touch control
- Over 6-8 hours of playtime on a single charge
Bluetooth 1.2 also comes with the added benefit of disrupting your wireless internet connection. Version 1 was prone to interference, so 1.2 was a great jump forward, all things said. When compared to 5.3, 1.2 is strictly left in the dust.
Bluetooth 5, and by proxy 5.3, saw a range boost of up to 800 feet. This is a significant increase over the likes of Bluetooth 4, which was no slouch in terms of overall connection distances. With Bluetooth 5.3, you could realistically take a modern pair of wireless earbuds and smartphone and roam your entire house while listening to your favorite music.
Yet again, you’ll see a stark difference between the two protocols. Bluetooth 1.2 doesn’t really have the throughput to accommodate a bunch of connections to the same device. You’ve got around 1 Mbps of transmission speed, which is great for 2003.
However, when looking at Bluetooth 5.3, you’ve got a massive increase in overall speed and bandwidth. Bluetooth 5.3 comes with the ability to send data at up to 50 Mbps, which is a huge jump forward. If you’re looking to transfer files over Bluetooth, like an AirDrop if you’re using an iPhone, then you’re going to have a wonderful experience.
Again, it does bear repeating that Bluetooth 5.3 was introduced in 2021 as a security update for version 5 of the protocol. It has an additional 18 years of development that Bluetooth 1.2 simply hasn’t received. As such, the performance and bandwidth of Bluetooth 1.2 are more in line with what the bleeding edge of technology was circa the early 2000s.
Overall compatibility with Bluetooth 1.2 is going to be higher. Bluetooth as a protocol is largely backward compatible with older devices. This means if you do happen to have a 1.2-enabled headset, headphones, or other devices, they’ll work with a newer smartphone. However, you’re not going to have an ideal time since it will default to 1.2 speeds and distances.
Bluetooth 5.3 is relegated primarily to newer smartphones and laptops. Something like the new Apple MacBooks and the latest iPhone 15 are going to have better support for Bluetooth 5.3 as a protocol. This isn’t an advantage necessarily, as you’re going to be paying quite a bit to get the latest wireless support.
However, if you’re prone to upgrading frequently, you’re likely in for a treat. Users who like holding off on upgrades for several years will likely notice a substantial leap forward in terms of overall connection strength and compatibility. That said, it won’t be immediately noticeable if you’re using an older phone or laptop.
Bluetooth 5.3’s power requirements are lower than 1.2’s. This is just the simple fact of the matter. As has been harped on again and again, Bluetooth 5.3 has more development and refinement behind it. You’ll notice less of a draw on both the accessory and its main connection than you would with older Bluetooth protocols.
Version 1.2 was good for its time, but used substantially more power to make and maintain a connection. This isn’t any fault of the protocol itself. It is more a product of its time and the limitations imposed by technology of the era.
Now, 21 years after the introduction of Bluetooth 1.2, it can be hard to justify the higher power requirements, lesser bandwidth, and overall less stable connections. If you want the best possible connection with the least power drawn, you’ll want to aim for devices using Bluetooth 5 or higher.
Bluetooth 5.3 vs. Bluetooth 1.2: 5 Must-Know Facts
- Bluetooth 5.3 has 50 times the bandwidth of Bluetooth 1.2.
- Bluetooth 5.3 can transmit up to 800 feet to a single source.
- Bluetooth 5.3 comes with the ability to utilize high-definition audio.
- Bluetooth 1.2 enabled the use of wireless devices without colliding with Wi-Fi signals.
- Bluetooth 1.2 was a substantial improvement over version 1 of the original protocol.
Bluetooth 5.3 vs. Bluetooth 1.2: Which One Is Better? Which One Should You Choose?
So, when it comes down to it, there isn’t a reason to pick Bluetooth 1.2. Now, if you happen to be some sort of retro mobile device enthusiast, there might be a reason to pick it up. However, if you’re looking for something that works with minimal hassle, Bluetooth 5.3 is going to be your best bet.
Yes, you’ll need a new device and accessories to take advantage of it. However, once you get past that, there are only benefits. Bluetooth 5.3 is a marked improvement over every previous version of the Bluetooth standard.
It is more stable and has better security. Once you also factor in the extreme distances it can connect over, it makes sense to opt for the latest and greatest. The only real drawback is that you’ll have to replace everything to use it.
