Xiaomi showcases 40W fast wireless charging technology which can charge 0-100% in 40 mins

Wireless charging tech on smartphones has been around for quite a while now. However, unlike other innovations in the smartphone world, wireless charging hasn’t caught up. While this low rate of adoption can be attributed to several reasons, there’s one major issue that has limited the spread of wireless charging on modern smartphones — slow charging speeds. At a time when a wired charging connection can, most likely, get your smartphone from 0-100% in just about an hour, most wireless charging solutions on premium flagships can barely match that performance.

In a bid to address this issue, several smartphone manufacturers have been working on more powerful and efficient wireless charging tech. For instance, earlier this year Xiaomi launched its Mi 10 flagship lineup in China, which features support for 30W fast wireless charging. The Mi 10 lineup was one-upped by Vivo’s APEX 2020 concept, which features support for 60W fast wireless charging. According to the company, the 60W wireless charging solution is capable of charging a 2,000mAh battery in just 20 minutes. But since the APEX 2020 is just a concept smartphone, we can’t expect its Super FlashCharge technology to make it to production devices anytime soon. Xiaomi, however, might bring a 40W fast wireless charging solution to its devices sometime later this year.

In a recent post on Weibo, the company’s co-founder Lei Jun revealed the company’s new wireless flash charging technology which boasts of 40W output capabilities. As seen in the video above, the new fast charging technology can charge a 4,000mAh battery from 0-57% (2,280mAh) in just 20 minutes, while taking about 40 minutes to get it up to 100%. In effect, this makes Xiaomi’s wireless flash charging technology faster than Vivo’s 60W Super FlashCharge. While it would be great to see this new technology in an upcoming Xiaomi device, the company hasn’t revealed any information about the release timeline for the same. It’s also worth noting that the phone in the video is a prototype/custom Mi 10 Pro.

Facebook’s 3D Photos are now supported on many Android devices with single cameras

Back at Facebook’s F8 developer conference in 2018, the company first announced a new feature for the platform called 3D Photos. As the name implies, the feature lets you post and view three-dimensional photos in your Facebook News Feed. The photos appear in your news feed like any other photos, but when you scroll past them, tap on them, or tilt your device, the 3D Photo’s perspective changes. You can also use virtual reality headsets like the Oculus Go or the Oculus Rift to view 3D Photos. At the time of launch, Facebook allowed users to create a 3D Photo only if you imported a depth map file on desktop and used a dual-camera phone like the latest Samsung Galaxy or iPhone devices. The reason behind the dual camera requirement was that Facebook could create a depth map from the images captured from both cameras. Now, however, dual cameras are no longer a requirement to create 3D Photos on Android phones.

As per a recent blog post from the company, Facebook now uses AI and machine learning to create a 3D Photo without any depth map data. As VentureBeat explains, the company has improved its machine learning algorithm such that it can infer the 3D structure of images without needing depth data. Additionally, the feature now works with selfies, paintings, and complex scenes as well.

To achieve this feat, Facebook trained a convolutional neural network using millions of pairs of 3D images and their depth maps. Once trained, this neural network is now being used to infer what a 3D image should look like without the accompanying depth map. This neural network can be run on typical mobile processors in a “fraction of a second,” making it suitable for the 3D photo feature. Google also enabled a similar feature in AR Core’s Depth API late last year, which allows the platform to create depth maps using a single camera.

However, even with the new advancements, the feature has some limitations. As per a report from Engadget on the matter, while any device can now view 3D Photos in the News Feed, the ability to post a 3D photo in Facebook’s app is limited to the iPhone 7 and newer, along with a couple of “midrange or better” Android phones, including Samsung’s Galaxy Note 8 and Note 9, as well as the entire Pixel lineup excluding the budget-friendly Pixel 3A. Along with this new development, it’s also worth noting that Facebook is currently testing an image editing suggestions feature for the photos you post on your News Feed.

Redmi K30 Pro Zoom Edition, Redmi Note 9, and Redmi 10X 4G names confirmed in MIUI 11

There are a handful of established players in the smartphone market; and thanks to how releases have worked out in the past, we have now fallen into a predictable pattern of releases. Every year few months, these established players release another iteration in their successful product lines, cashing in rightfully on the hard-earned goodwill from those lines. So when we hear about Xiaomi working on the Redmi Note 9, we aren’t really surprised. But when we hear about Xiaomi working on a Redmi K30 Pro Zoom Edition and Redmi 10X, we do take notice.

XDA Senior Member kacskrz discovered the names of a few upcoming Xiaomi/Redmi smartphones in the latest MIUI 11 China Developer ROM. These include:

  • Redmi K30 Pro
  • Redmi K30 Pro Zoom Edition
  • Redmi Note 9
  • Redmi 10X 4G

Of these, we already know that Xiaomi is going to launch a Redmi K30 Pro flagship smartphone in China. Xiaomi has also revealed that the Redmi K30 Pro will come with the Qualcomm Snapdragon 865 SoC as well as 5G capabilities. However, this is the first mention of a special “Zoom Edition” of the flagship. We do not know what exactly is special about this “Zoom Edition”, but judging from its name, it may obviously have something to do with better zoom capabilities on the phone.

As for the Redmi Note 9, there is no surprise that it is in the works. According to market research firm Canalys, the Redmi Note 7 had a spot in the top 10 selling smartphones globally in 2019, while the Redmi Note 8 and Redmi Note 8 Pro both occupied spots in the top 10 selling smartphones globally for Q4 2019. In fact, the Redmi Note 8 was the best selling Android smartphone for Q4 2019 — so it was entirely expected that Xiaomi would follow up with a successor.

The Redmi 10X 4G is a peculiar find. Xiaomi has sold several “X” phones as part of its Mi series, like the Mi 5X and Mi 6X. However, this is the first time we are hearing of a “Redmi #X” phone. We do not know what is special about this phone outside of the name. We speculate that the 10X could refer to either zoom capabilities (following the theme from the K30 Pro Zoom Edition), or it could be variant of the Redmi 10 (unlikely, since the Redmi 9 is yet to be released, pushing the Redmi 10 and then Redmi 10X to even further timelines). Curiously, the name also includes the words “4G’, which indicates that there might also be a 5G variant in the work.

We’ll let you know when we receive more information about these upcoming phones.

Opinion: Waterfall Displays are the Future of the Glass Slab Smartphone

Curved screens have been one of the more controversial additions to phones in the past few years. A lot of phone enthusiasts dislike the extreme curves as they pose practical usability issues. Other people swear by curved displays, claiming that the look and feel of the curves are worth the usability trade-offs. This has been a hotly-debated topic and it seems as though some OEMs have decided to go to the extreme with “waterfall” displays. In my opinion, curved screens are here to stay and they are evolving into the new waterfall display.

The waterfall display can be found on two different devices at the moment, the Huawei Mate 30 Pro and Vivo Nex 3. Both of these devices have displays that curve so drastically that they wrap around to the sides of the device. This means there aren’t even physical volume buttons on the side. In theory, this sounds like it’s going to be a horrendous experience from both ergonomics and palm rejection. In reality, it makes for an absolutely incredible feeling device that also looks futuristic.

I’ve had both the Vivo Nex 3 5G and Huawei Mate 30 Pro for four months and have used both extensively. Both have different takes on the waterfall display and how it should work with buttons and user interactions.

Left: Huawei Mate 30 Pro. Right: Vivo Nex 3 5G.

The Vivo approach is probably my favorite of the two. While Huawei maintains a physical power button, Vivo removes all physical buttons from the sides of the phone. Instead of physical buttons, Vivo opted to use pressure-sensitive buttons for the volume rocker and power button. All you need to do is press where the button would be and it will work. You do get nice haptic feedback from the absolutely fantastic haptic motor to know when the button was pressed successfully.

If you’re wondering how you turn on your device since these aren’t hardware buttons, don’t worry. The pressure-sensitive buttons work when the phone is turned off! You pretty much never need to press a physical button. Vivo has included a physical power button on the top as a backup just-in-case something random happens and you aren’t able to use the pressure-sensitive buttons on the side.

This doesn’t sound like a normal phone experience, right? To the best of my knowledge, there has yet to be a phone that has come to market without the dominant buttons being physical switches. This is super weird and yet I’ve come to prefer pressure-sensitive buttons to physical buttons. The combination of superb haptics and incredible false button more than make up for the lack of physical buttons. I actually wish more manufacturers would copy Vivo and include this in their phones.

The Huawei method is a bit more conventional, but only slightly. Huawei basically shoves the power button into the side aluminum frame of the device. Describing it sounds normal until you remember, the glass and display basically make up the sides of the phone. You still have some aluminum there, but it’s towards the back of the phone. Basically, the power button is further back on the device frame than it is on most phones. This honestly isn’t a big deal and you get used to it very quickly.

Huawei did remove the volume buttons from the Mate 30 Pro, which leaves us in a weird position. There are no pressure-sensitive or capacitive buttons on the side, so there is no mechanical way to change the volume. Instead, you need to use this funky double-tap gesture. You just double tap on the top half of the side of the display on either side. It’s honestly an annoying and unnecessary gesture. I really hope OEMs don’t follow Huawei’s user experience if waterfall displays do catch on.

What about palm rejection? Well, it’s never been an issue in my experience. I haven’t had issues with the device randomly getting touches from my hands or randomly changing the volume while holding it. The algorithms these companies are using are very good. I wouldn’t even consider palm rejection an issue on most modern curved phones. As long as you hold the phone like a normal human being, you’ll be good.

I know that was a lot about the user experience and how it affects general phone functions. What about ergonomics and durability? To fully grasp the idea of waterfall displays, you really need to understand what they are. Simply put, it’s a large display with curves that fall over the sides of the phone like a waterfall. The screen essentially becomes the sides of the phone.

So about durability? Well, I don’t think it’s a major concern, but it is something people will wonder about. For the record, both the Mate 30 Pro and Nex 3 come with a case in the box and I’d expect most waterfall display phones to do the same. It’s a good way to make sure your phone is protected no matter where you go. You may not love the idea of covering such an eye-catching design in a case, though. But this is not a unique problem for waterfall phones.

The main reason I’m not concerned about durability is these phones really aren’t that different. When most phones are dropped, they are dropped on one of the corners or the front/back. The back of a waterfall phone is unchanged from basically any other phone, so you’ll have the same durability issues. Similarly, the corners are not hugely different from other phones, especially those with less extreme curved displays. Dropping any phone on a corner is not good.

The weak point of a waterfall display is where the curved display meets the back, creating a sharp edge. This edge is not as protected as the edge of a display on a normal smartphone. Other phones have more material on the sides to protect the display, but on a waterfall phone, the display is actually on the side. So if you drop the phone and the side hits something or lands just right, you could have a problem. Is this likely to happen? Probably not, but it could.

After that, it’s all about looks. Looks, of course, are subjective. To be honest, I really like the look. The waterfall display looks fantastic while down on a table or even in your hand. It just looks futuristic and feels absolutely fantastic to hold. These design traits just make for devices I want to keep using. They are comfortable, sleek, and all-around great.

Alleged Motorola One 2020 Device

I’m glad more OEMs are taking a look at these displays and adding them to their own devices. The Huawei Mate 30 Pro and Vivo Nex 3 are the only two waterfall display devices at the time of publishing, but there are more on the way. Soon, Motorola is going to launch the Motorola Edge+ and a mid-range sibling with  waterfall displays. I can only imagine what other OEMs have in the works. I’m really excited to see all of these new devices and actually get to use them.
