Bluetooth 6.0: What You Need to Know About the Future of Wireless Headphones

Bluetooth got a major upgrade, and it’s already showing up in phones and headphones. Here’s what to expect and what we’re still waiting for.

The Bluetooth Special Interest Group announced version 6.0 of the near-ubiquitous wireless technology in Sept. 2024, adding some major new features that aim to improve Bluetooth’s reliability, security, smoothness and efficiency. It might even get you a greater range between your headphones and phone, as well as longer battery life. 

We’re finally seeing devices arrive with Bluetooth 6.0, including phones from Apple and Google, as well as headphones and earbuds. Here’s what you need to know about Bluetooth 6.0 and how it will affect wireless connectivity for years to come. 

Main improvements of Bluetooth 6.0

Latency

Latency is the time between an audio signal being sent and when you actually hear it. The higher the latency, the more annoying it can be — think of when the sound lags behind the video in movies or games. Most Bluetooth (5.0 and newer) devices have latency somewhere between 50 to 100 milliseconds, depending on gear and configuration, which is noticeable to most people. 

Bluetooth 6.0’s new isochronous adaptive layer, or ISOAL, allows devices to break up audio data into smaller chunks for quicker processing. In theory, this has the potential to reduce latency, and it’s possible that we might see latency under 10 milliseconds under ideal conditions, such as close range, no obstacles and no interference. 

We expect that under real-world conditions, the majority of setups will operate at a latency of around 20 milliseconds, which would still represent a significant improvement over Bluetooth 5.x. 

Location tracking and security

One of the new spec’s most buzzworthy features is called Channel Sounding, which provides a significant improvement in the accuracy of device location tracking. It relies on a back-and-forth exchange of data packets between connected devices and a combination of time stamps and frequency analysis, rather than the old, less accurate method of just measuring relative signal strength. 

Channel Sounding is a boon for Apple’s Find My and its Google and Samsung equivalents, offering location accuracy down to approximately 10 centimeters, along with improved resistance to obstacles and interference. It also enables enhanced security for Bluetooth lock systems using a combination of encryption, randomization and location cross-referencing to ensure some random person isn’t unlocking your car or front door. 

Power efficiency and pairing speed

The same features that reduce latency also help with power efficiency: Everything behaves intelligently to use more power for keeping audio and video in sync for things like gaming, and less power for less intensive applications like audiobooks. This flexibility is especially crucial for wireless earbuds, which require the most effective power management due to their compact size. 

The process of scanning for nearby Bluetooth devices is also being upgraded, with decision-based advertiser filtering and monitoring. Advertising in this case doesn’t refer to selling you products. Basically, it’s a set of headphones broadcasting, «I’m a headset, and I’m nearby and ready to connect.»  

Instead of constantly shouting, «Is anyone there?!» to see if there’s anything nearby to connect to, Bluetooth 6.0 devices will keep track when previously paired devices go in and out of range. This should save precious battery life, make pairing quicker and provide smoother multipoint switching.

What Bluetooth 6.0 doesn’t do

Improved Bluetooth sound quality (maybe)

Were you waiting for reliable, wireless lossless audio transmission from your phone to your headphones? Still not there yet. 

Astute readers who note that CD-quality lossless audio transmission requires 1.4Mbps of throughput speed may wonder why Bluetooth 6.0’s theoretical 3Mbps isn’t enough. It’s because much of Bluetooth’s bandwidth is taken up by overhead — a bunch of ancillary data that’s required for secure Bluetooth connections that has nothing to do with audio. While there are some codecs that promise high-quality wireless audio, lossless CD-quality audio remains elusive.

Bluetooth 6.0 does bring the optional long-discussed LC3plus codec, which can transmit up to 24-bit and 96kHz audio. However, unlike «regular» LC3, this is an optional codec that has a separate licensing fee. That means there will be limited adoption compared to the more popular codecs. Remember, both your device and headphones must be compatible with LC3plus for it to work. How well it works and whether it can reliably transmit 24/96 in the real world remain to be seen.

A future incremental revision of Bluetooth 6.0 promises to add a high-data-throughput feature that will open up usable bandwidth for lossless streaming, potentially by using other frequency bands besides the crowded 2.4GHz band, to achieve speeds of up to 7.5Mbps. That should provide enough headroom to enable high-res audio streams, though it’s unclear if manufacturers will adopt the right codecs for lossless Bluetooth audio via headphones. Given past and current adoption rates for different Bluetooth codecs, it is unlikely to be Apple, and this technology will instead first find its way into lesser-known Android phones.

Where to find Bluetooth 6.0 right now

If you want to get a head start on Bluetooth 6.0 compatibility, there are a handful of devices already shipping (though not all of these are available in the US).

The 3 iOS Features You Definitely Aren’t Using (but Are Silently Draining Your Battery)

If you find that your phone loses battery too fast, you may just need to disable these features to solve the problem.

It’s 2026, and if you’re constantly toggling on «Low Power Mode» just to survive a commute, you may as well be carrying around a brick. While it’s true that lithium-ion batteries naturally degrade over time, most people are draining their «juice» prematurely by leaving on high-performance features they don’t even need. 

Your iPhone has a few key settings that drain your battery in the background. The good news is, you can turn them off. Instead of watching your battery percentage plummet at the worst possible moment, a few simple tweaks will give you hours of extra life.

Before you even think about buying a new phone, check your Battery Health menu (anything above 80% is decent) and then turn off these three settings. It’s the easiest way to make your iPhone battery last longer, starting right now.

Turn off widgets on your iPhone lock screen

All the widgets on your lock screen force your apps to automatically run in the background, constantly fetching data to update the information the widgets display, like sports scores or the weather. Because these apps are constantly running in the background due to your widgets, that means they continuously drain power.

If you want to help preserve some battery on iOS 18, the best thing to do is simply avoid widgets on your lock screen (and home screen). The easiest way to do this is to switch to another lock screen profile: Press your finger down on your existing lock screen and then swipe around to choose one that doesn’t have any widgets.

If you want to just remove the widgets from your existing lock screen, press down on your lock screen, hit Customize, choose the Lock Screen option, tap on the widget box and then hit the «« button on each widget to remove them.

Reduce the motion of your iPhone UI

Your iPhone user interface has some fun, sleek animations. There’s the fluid motion of opening and closing apps, and the burst of color that appears when you activate Siri with Apple Intelligence, just to name a couple. These visual tricks help bring the slab of metal and glass in your hand to life. Unfortunately, they can also reduce your phone’s battery life.

If you want subtler animations across iOS, you can enable the Reduce Motion setting. To do this, go to Settings > Accessibility > Motion and toggle on Reduce Motion.

Switch off your iPhone’s keyboard vibration

Surprisingly, the keyboard on the iPhone has never had the ability to vibrate as you type, an addition called «haptic feedback» that was added to iPhones with iOS 16. Instead of just hearing click-clack sounds, haptic feedback gives each key a vibration, providing a more immersive experience as you type. According to Apple, the very same feature may also affect battery life.

According to this Apple support page about the keyboard, haptic feedback «might affect the battery life of your iPhone.» No specifics are given as to how much battery life the keyboard feature drains, but if you want to conserve battery, it’s best to keep this feature disabled.

Fortunately, it is not enabled by default. If you’ve enabled it yourself, go to SettingsSounds & Haptics > Keyboard Feedback and toggle off Haptic to turn off haptic feedback for your keyboard.

These Are the Weirdest Phones I’ve Tested Over 14 Years

These phones tried some wild things. Not all of them succeeded.

I’ve been a CNET journalist for over 14 years, testing everything from electric cars and bikes to cameras and, er, magic wands. But it’s phones that have always been my main focus and I’ve seen a lot of them come and go in my time here. Sure, we’ve had the mainstays like Apple and Samsung, but I’ve also seen the rise of brands like Xiaomi and OnePlus, while once-dominant names like BlackBerry, HTC and LG have vanished from the mobile space. 

I’ve seen phones arrive with such fanfare that they changed the face of the mobile industry, while others simply trickled into existence and disappeared just as uneventfully. But it’s the weird ones that stick in my memory. Those devices that tried to be different, that dared to offer features we didn’t even know we wanted or simply the ones that aimed to be quirky for the sake of quirky. Like someone who thinks an interesting hat is the same as having a personality. 

Here then are some of the weirdest phones I’ve come across in my mobile journey at CNET. Better yet, I still have them in a big box, so I was able to dig them out and take new photos — though not all of them still work. Let’s start with a doozy. 

BlackBerry Passport

At the height of its power RIM’s BlackBerry was one of the most dominant names in mobile. It was unthinkable then that anything could unseat the goliath, let alone that it would fade into total nonexistence. The once juicy, ripe BlackBerry withered and died on the bush, but not without a few interesting death rattles on its way.

My pick from the company’s end days is the Passport from 2014, notable not just for its physical keyboard but its almost completely square design. The rationale behind this, according to its maker, was that business types just really love squares. A Word document, an Excel spreadsheet, an email — all square (ish) and all able to be viewed natively on the Passport’s 4.5 inch display with its 1:1 aspect ratio. Let’s not forget that all Instagram posts at that time were also square so it had that going for it too. YouTube, not so much.

In theory it’s a sound idea. In practice the square design made it awkward to use, as the physical keyboard was too wide and narrow. Its BlackBerry 10 software, especially the app availability, lagged behind what you’d get from Android at the time. BlackBerry quickly ditched the new shape. After trying to claw back some credibility with its Android phones — including the stupidly named Priv, a phone I quite liked — and by bringing on singer Alicia Keys as Global Creative Director (because BlackBerry phones had keys, get it?) the company stopped making its own phones in 2016.

YotaPhone 2

You’d be forgiven for having never heard of this phone or its parent company, Yota. Based in Russia, Yota made two phones: the creatively named YotaPhone in 2012 and the similarly inspired YotaPhone 2 in 2014, pictured above. Both were unique in the mobile world for their use of a second display on the rear. From the front, these phones looked and operated like any other generic Android phone. Flip them over though and you’d get a 4.3-inch E Ink display.

The idea was that you’d use your Android phone as normal for things like web browsing, gaming or watching videos, but you’d switch to the rear display if you wanted to read ebooks or simply have it propped up to show incoming notifications. E Ink displays use almost no power, so it made a lot of sense to preserve battery life by viewing «slow» content on the back. 

The reality though is that beyond ebooks — which aren’t great to read on such a tiny screen anyway — there’s very little anyone might want to use an E Ink display for when out and about. It was difficult to operate, too, thanks to a slow processor and clunky software. After just two generations of YotaPhones, the company went into liquidation.

HTC ChaCha

Remember when Facebook was the cool place to be instead of just the place your parents and their friends go to publicly air their most troubling of opinions? When I was at university, instead of trading phone numbers when you met someone, the default thing was to add each other on Facebook and then begin poking each other. Facebook was so ubiquitous at the time that it was simply the way every single person I knew communicated. 

Keen to capitalise on Zuckerberg’s social media success, HTC brought out the ChaCha in 2011. The phone came with an utterly ludicrous name and a dedicated Facebook button on the bottom edge. Tapping this would immediately bring up your Facebook page, allowing you to post the lyrics to Rebecca Black’s Friday, ask what Fifty Shades of Grey is about or do whatever else it was we were all up to in 2011. 

Facebook might still be around in one form or another, but HTC abandoned its phone-making business back in 2018. Unsurprisingly, phones with dedicated hardware buttons tied to social media haven’t caught on.

Sirin Labs Finney U1

«Bro!» I hear you shout, all-too loudly. «BRO! You’ve got to check out what my Bitcoin is doing!» You’d then show me your phone and I’d watch while your crypto account plummeted, rebounded and plummeted again over the course of 12 seconds. The phone you’d be showing me, of course, would be the Sirin Labs Finney, a 2019 phone specifically targeted at crypto bros who wanted a device that would perfectly match their high-living, high-fiving crypto-trading lifestyle. 

At its core, the Finney is just another Android phone, but a hidden second screen pops up from the back of the phone, with the sole purpose of giving you secure access to your crypto wallet. The phone had a whole host of security features to ensure that only you could access your Bitcoin or Etherium, and it allowed you to send and receive cryptocurrency without having to use a third-party online platform. Apparently that was a good thing.

If you were entrenched in the crypto world, this phone might have been the dream. But the wallet wasn’t easy to use and the phone was expensive, thanks to the cost of that second screen. Sirin Labs stopped making phones soon after and the mobile industry learned an important lesson about not developing hyper-niche devices that aren’t even that well-suited for the handful of customers that might be interested.

Planet Computers Gemini PDA

Half phone, half laptop, all productivity. The Gemini PDA by UK-based mobile startup Planet Computers was a clamshell device in 2018 with a large (at the time) 5.99-inch display and a full qwerty keyboard. It was basically a slightly more modern interpretation of a PDA, like 1998’s Psion 3MX, in that it was effectively a tiny laptop that would fold up and fit in your pocket. The full keyboard allowed you to type away comfortably on long emails or documents while the regular Android software on the top half meant it also functioned like any other phone — apps, games, phone calls, whatever. 

It had 4G connectivity for fast data speeds and a later model even got an update to 5G. But, like the BlackBerry Passport, its focus on business-folk and productivity above all else meant it was a niche product that failed to garner enough appeal to succeed. It didn’t help that it was utterly enormous and fitting it in a jeans pocket was basically impossible, so it didn’t impress either as a laptop or as a phone. 

LG G5

LG remains a huge name in the tech industry today thanks to its TVs and appliances, but it also tried to be a big player in the phone world, too. I liked LG’s phones — they were quirky and often tried weird things which kept my days as a reviewer interesting, perhaps none more so than the LG G5 in 2016. 

LG called the G5 «modular,» meaning that the bottom chin of the phone snapped off allowing you to attach different modules such as a camera grip or an audio interface. Like many items on this list I can say that it’s a nice idea in theory, but in practice the phone fell short. Swapping out modules meant removing the battery, which of course meant restarting your phone every time you wanted to use the camera grip. 

It was an inelegant solution to a problem that never needed to exist. But its bigger issue was that the camera grip and audio interface were the only two modules LG actually made for the phone. It’s as though the company had this fun notion in creating a phone that can transform according to your needs but then forgot to assign anyone to come up with any ideas on what to do with it. As a result, the end product was uninspiring, over-engineered and expensive.  

Samsung Galaxy Note

Samsung’s Galaxy Note series helped transform the mobile industry. It literally stretched the boundaries of phones, encouraging larger and larger screens — even creating the unpleasant and mercifully short-lived term «phablet.» But the first-generation model in 2011 was controversial, mostly due to what was then considered its enormous size. 

At 5.3 inches, it was significantly bigger than almost any other phone out there, including Samsung’s own Galaxy S2 — which, at a measly 4.3 inches, paled into insignificance against the mighty Note. It was mocked for being so huge, with memes appearing online poking fun at people holding it up when making calls. And while times have changed and we now have Samsung’s 6.9-inch Galaxy S25 Ultra, the original Note’s boxy aspect ratio meant it was actually wider than the S25 Ultra. So even by today’s standards it’s big.

It was also among the first phones to come with its own stylus shoved into its bottom. It’s a feature that few mobile companies have mimicked, but Samsung kept it as a differentiator on its later Note models before incorporating it into its flagship S line starting with the S22 Ultra. 

Nokia Lumia 1020

Nokia’s Lumia 1020 was my absolute favorite phone for quite some time after its launch in 2013. And it’s because of its weirdness. 

Nokia had an amazing history of bonkers mobiles — 2004’s 7280 «lipstick phone,» for example — and while the Lumia range was much more sedate, the 1020 had a few things that made it stand out. First, it ran Windows Phone, Microsoft’s brief and unsuccessful attempt to launch a rival to Android and iOS. A rival that I happened to quite like. 

It was also made of polycarbonate, with a smoothly rounded unibody design that strongly contrasted the angular metal, plastic and glass designs of almost all other phones launching at that time. Its look was unlike anything else on sale, and I loved it.

But the main thing I loved was its camera. With a 41-megapixel sensor, Carl Zeiss lens, raw image capture and optical image stabilization, the Lumia 1020 packed the best camera specs of any phone I’d ever seen. It made the phone a true standout product, especially for photographers like me who wanted an amazing camera with them at all times, but didn’t want to have to carry both a phone and a compact digital camera. 

While incredible image quality from a phone is a given in almost all camera phones in 2026, the Lumia 1020 was an early pioneer in what could be achieved from a phone camera. 

LG G4

LG, twice in one list? Oh yes, my friend, because the G5 seen above was not the first time LG went weird. Launched in 2015, the LG G4 had two main features that raised a few eyebrows. Most notably was LG’s decision to wrap the phone in real leather. Yes, real actual leather. Like what you’d get when you peel a cow. It even had stitching down the back, making it look like a handbag or a boot.

While it’s not a phone for vegans, I actually liked the look, especially as real leather — even the really thin stuff LG used on the G4 — naturally wears over time, gaining scuffs and scratches that give each phone a unique patina. It’s why I love my old leather Danner boots, and it’s why a vintage, worn-in leather jacket will almost always look better than a brand new one. Still, with leather being an expensive — and arguably controversial — material to use on a phone, it’s no surprise LG didn’t return to this idea.

But it’s not the only weird thing about the phone — the G4 was among a small number of phones released around that time that experimented with curved displays. It’s gently bent into a banana shape, the theory being that it makes watching videos more immersive, as is the case with curved screens in movie theaters. The problem is that movie screens are immense, so that curve makes sense. On a 5.5 inch phone like the G4, that curve is barely noticeable and only really served to push the price up. 

Motorola Moto X and Moto Maker

I’ve just pointed out how weird the LG G4 was for using leather and now I’m pointing out another phone that, as you can see in the image above, is also wrapped in leather. But the weird thing here isn’t that the Motorola Moto X came in leather — it’s that I personally got to choose that it came in leather. 

With the Moto X in 2013, Motorola launched a service called Moto Maker that allowed you to customize your phone in a wild variety of ways. From different-colored backs and multicolored accents around the camera and speakers through to using materials including leather and even various types of wood, there were loads of options to make your Moto X look unique. Each phone would then be made to order and you could even have it personalised with lazer etching and provide your Google account for it to be prelinked on arrival. 

If custom-making phones with a vast number of potential options en mass sounds like an absolute logistical nightmare then you’re on the same page as Motorola eventually found itself. Moto Maker only existed for a few years before the company retired its customization service. 

Samsung Galaxy Fold

I’m ending on a wildcard addition with the original Galaxy Fold. It’s a wildcard because Samsung’s Fold and Flip range are now up to number seven and we’ve got foldable devices from almost all major Android manufacturers. Though still not Apple. 

While the original Fold might have kicked off the foldable revolution, there’s no question it was a weird phone. I was among the first to test it in the world when it launched in 2019 and while I was certainly impressed by the bendy display, its hinge felt weird and «snappy» to use. The outer display was, let’s face it, terrible. 

On paper its 4.6-inch size is reasonable, but it’s so tall and narrow that it was borderline unusable for anything more than checking incoming notifications. Trying to type on it meant whittling down your thumbs to pointy nubs so I spent most of my time interacting with the phone’s much bigger internal screen. Cut to today when the Galaxy Z Fold 7’s outer screen measures a healthier 6.7 inches and as a result can function like any regular smartphone, with the bigger inside screen only required when you want more immersive content.

Looking back at the original Fold and its bizarre proportions, it’s honestly a surprise that Samsung persisted with the format. But I’m glad it did.
