Our devices have changed over the years, but the need to keep them charged while on the go hasn’t. UGREEN just released a massive charging bank that’s guaranteed to keep your devices charged whether you have a phone, tablet, or computer. It’s the UGREEN 25,000mAh charging that can deliver a whopping 145W of power.
Portable charging banks typically come in a range of capacities, but they’re usually low. They’re to keep your phone from dying while on a trip. However, this portable charger takes things to the next level.
This UGREEN charging bank also has blazing-fast charging
One of the main areas where typical power banks fall short is the charging speed. It doesn’t matter if your phone supports fast charging when connected to the wall. Most banks just aren’t built to deliver a lot of power at once. This power bank flips the script.
The UGREEN power bank supports PD3.0 and QC3.0, and it can deliver up to 145W of power. Since some new phones come out with 120W fast charging, you’ll know that you’re covered no matter how fast your device’s charging is.
Most new phones from Chinese companies give their phones 120W charging. Even the new Samsung Galaxy Books have 68W charging. It doesn’t matter what the device is, it’ll be charged up quickly.
What if you have more than one device? No worries, as this power bank can charge three devices at the same time. Why not charge your tablet alongside your phone? You can do that to keep productive. You won’t need to plug your phone into your computer just to keep it charged.
Speaking of computers, you’re able to charge your computer as well. If your computer charges via the USB port, then you can plug into this power bank. It has a massive 25,000mAh capacity, so there’s a ton of power to feed off of.
The company says that it can charge a 2022 13″ Macbook Air in just 90 minutes. You won’t have to worry about your computer dying on you if you’re out and about.
If you’re looking into picking one of these power banks up, you can order it from Amazon US and Amazon UK. It costs $149.99/£139.99.

Motorola is back with the Razr, and its second true attempt at a foldable. And on the surface, it seems like Motorola has really hit out of the park. Motorola addressed basically everything that users complained about with other flipping phones, and also lowered the price. That includes adding a larger cover display, a larger battery that lasts longer, and a cheaper price tag. But was that enough to make the Motorola Razr+ a best-seller for the company? It might be. But let’s find out in our full review.
Table of Contents
Motorola Razr+ Review: Hardware & Design
The design of the Motorola Razr+ is actually a bit different than you might expect from Motorola. With their previous foldable, they did keep some of the unique design choices that made the Razr so popular in the 2000s. After all, the Razr v3 did sell over 130 million units worldwide, so it was a big seller for the company. So it makes sense to reuse that name here. But it didn’t make sense to keep the chin.
With the Razr+, the chin is gone. That does get rid of one of its more differentiating factors however. And now, it looks like every other flipping phone on the market. And it has less of an industrial design this time around.
Motorola has outfitted the Razr+ with curved sides, which make it feel better in the hand. It also has the power button and volume rocker on the right-hand side. The power button also doubles as a fingerprint sensor. Making it easier than ever to get back into your Razr+. That fingerprint sensor works really well, and I really wish every phone went with a power button fingerprint sensor.
On the opposite side, you’ll find the SIM card slot. While there is support for eSIM, it is not the only way to use the Razr+. Unlike the iPhone 14 series which is eSIM only. So that’s good to see.
The back of the phone is going to be frosted glass, unless you get the Viva Magenta color (exclusive to T-Mobile and Motorola.com) which is a vegan leather back. It feels great in the hand, whether folded or not. Inside, you’ll find the massive 6.9-inch display, along with the cut out for the front-facing camera, and a lifted bezel. This is the case for most foldables these days, where the bezel is actually raised, to protect the folding display.
Let’s address the elephant in the room. It does not fold completely flat. This isn’t new. Most foldables do not fold completely flat, because of the hinge. But it became a big deal after a few leaks of the Pixel Fold came out, saying it didn’t fold flat. That’s still the case here on the Razr+. But you won’t notice, unless you are looking for it.
It’s one of the most stunning foldables I’ve seen, so far. Now, this does come ahead of Samsung announcing the Galaxy Z Flip 5 (and Fold 5) next month, so that might change. But Motorola has really hit it out of the park, at least from a hardware and design standpoint.
Motorola Razr+ Review: Display
Like most foldables, the Razr+ does have two display. The inner display is a 6.9-inch FHD+ 165Hz AMOLED display. While the outer display is a 3.6-inch 144Hz AMOLED display, it has a resolution of 1056×1066, so it’s almost a square.
The inner display is quite nice actually. It’s great to see Motorola using a proper AMOLED here instead of a pOLED display. While they are similar, AMOLED displays are a lot more vibrant and reproduce color a lot more than pOLED does. It’s really a great display, with one problem. It’s a problem that I’ve gotten used to with the Razr+, and that’s the aspect ratio. This is a taller device than most others on the market. With the inner display being a 22:9 aspect ratio. This makes it tougher to reach the top of the display, when using it one hand.
Now, I don’t know for sure, but I’d assume that making this taller is what allowed for the larger front-display on the Razr+. Though, a slightly wider phone wouldn’t be too bad either. It’s something you’ll get used to after a few days, but it’s another thing to keep in mind.
Large Front Displays are in
I spent a good two months using the Galaxy Z Flip 4 as my daily driver last year, because it was really the first Flip phone that had decent battery life – thanks to the Snapdragon 8+ Gen 1, the same chipset in the Razr+. And the main thing I disliked about the Flip was, having to open it tens if not hundreds of times a day for every little thing. With the Razr+, you don’t need to.
The front display can be used to reply to emails as well, as it can fit the entire keyboard on that screen. Now it will be hard to see what you’re typing, but it is possible. I’d say you’re more likely to reply to text messages, than write an email with this screen. Unless it’s a super short email.
Apps do work on the front display, and in fact, every app works on it. Motorola said that they built it so that any Android app should work on the display, some will look better than others, however. We did try a number of apps on this front display. Particularly ones that don’t generally work well on these weird aspect ratios, like Instagram. And it worked. Now was Instagram the best looking on this square display? No, of course not. But it does work. Other apps we tried included Twitter, Amazon, and Google News, to name a few. They all worked, but other than Twitter, I’d prefer to use them on the internal display.
Since this outer display is a 144Hz panel, you might be thinking about games. And yes, there are some games that work here. They are powered by the Game Snacks that Google has been working on for Android Auto. Which is pretty interesting. There’s games like Marble Mayhem which you have to tilt the phone to get the marble through the maze, and then it drops into the camera. Which is neat. Other games that are pre-installed include Astro Odyssey, Scooter Xtreme, Tiger Run, Stack Bounce and 99 Balls 3D. Obviously, these are not AAA games, and really lightweight games. Which is what you’d expect for playing on such a small display.
These are mostly games you’d play when you have time to kill, like waiting at a doctor’s office, or something like that. Probably not something you’d use often, but still cool to have.
Motorola Razr+ Review: Performance
Inside the Razr+, there’s the Snapdragon 8+ Gen 1, with 8GB of RAM and 256GB of storage. Now some of you might have noticed, that is an older processor. It is, but it’s not that old. It’s just now hitting a year since it was announced. But it’s still a really good processor, and that is likely how Motorola was able to put the Razr+ out for under $1,000.
The Snapdragon 8+ Gen 1 performs as well here as it has on every other phone that has used this processor over the past year. That means that it is pretty fast, while staying cool, and very battery efficient. While using the Razr+, I never really noticed any overheating. Now, the phone did get hot while using the camera for extended periods of time and playing games, as it would normally. But otherwise, it was pretty cool.
For others 8GB of RAM likely feels like its kind of old at this point. But it’s plenty of RAM. When using the Razr+, apps didn’t really need to be redrawn, and it did keep apps in memory quite nicely. That’s surprising, compared most other Android smartphones from Google and Samsung do not do that, with the same amount of RAM.
Overall, performance here was quite nice. It’s not the most powerful smartphone on the market, but it does a good job at everything it needs to do. And everything you might throw at it.
Motorola Razr+ Review: Battery life & Charging
This section is going to have some good, and some bad news. Let’s start with the good news, battery life.
Battery life on the Motorola Razr+ hit my expectations. Comparing it to the Galaxy Z Flip 4, which has a slightly smaller battery at 3700mAh, while the Razr+ has a 3800mAh battery. And the processor is the same, while the Razr has a slightly larger display and a higher refresh rate. I figured I’d get about the same battery life, and, I was actually wrong. The Razr+ outperformed the Galaxy Z Flip 4, slightly.
When I reviewed the Galaxy Z Flip 4 last year, I was usually getting six or seven hours of screen on time. With the Razr+, I’ve been getting eight hours on most days, but no less than seven hours. That’s pretty good. Not quite on the level of some non-folding phones like the Galaxy S23 Ultra, but it is better than the Pixel 7 Pro.
Wireless charging should have been skipped
Now, onto the bad news. Charging speeds. Motorola has pretty decent wired charging speeds at 30W. Sure, faster would be nice, but even at 3800mAh, this does charge pretty quickly. The bad news though, is the wireless charging speed. It’s 5W, which is just, so bad. That’s about as slow as you can get. Now, I understand that Motorola was looking to cut some corners and save money, while also protecting the battery. But 5W? Motorola should have just omitted the wireless charging and maybe given us a slightly larger battery with that space.
The other bit of bad news is, Motorola is joining the OEMs that no longer include the charger in the box. Now, Motorola did include a charger in our reviewers kit, but that won’t be in the retail boxes that ship in late June. Most of us likely have a 30W capable USB-C charger, but if not, you’ll need to buy one.
Motorola Razr+ Review: Software
For the most part, Motorola has stuck to a vanilla Android approach on its phones. And that includes the Razr+. So you’ll notice that it is very similar to what the Pixel offers. Though it does ditch some of the annoyances of the Pixel software, like the battery life screen only updating every two hours – obviously, that’s really only an issue for reviewers like myself.
With Motorola sticking to a vanilla approach here, that does mean that Material You is available on the Razr. But it’s not the same method as other smartphones. Basically, it’s not located in the Wallpaper screen. Instead, long-press on the home screen and tap on Personalization. In here, you’ll see a number of options for personalizing the Razr+. This includes themes, fonts, colors, icon shapes, and so much more. In the colors section, you’ll find the Material You options for the icons. It includes basic colors and wallpaper colors. So it uses a single shade instead of up to four shades, like stock Android uses. It’s unclear why this is, but it is what it is.
Motorola has added some curated live wallpapers that react to you opening and closing the Razr. Like a flower opening as you open the Razr and closing as you close it. It’s the little things that make all the difference and this is one of them. Of course, you can set any wallpaper you’d like, but some of these are really cool, to be quite honest.
The company has also added a ton of gestures that you can use on the Motorola Razr, to get the most out of this phone. Like the Sidebar, which is a quick way to jump into other apps for multitasking. You can also turn on gestures to double-tap the screen to put the phone to sleep or wake up. Interestingly, these are two separate options. So you can turn one on for turning off the display and keep the one off for turning on the display, if you wish to do so.
Motorola also allows you to swipe across the screen to jump into split screen mode. Making it much easier then going to the recents menu and doing it. And there’s so many more. If you go to Settings > Gestures, you’ll find about 20 different options there. Of course, an oldie but goodie is still there. And that’s the chop to turn on the flashlight. That’s a gesture Motorola added on the original Moto X, way back in 2012, when Google owned them.
The software on the Motorola Razr+ is really fluid and I have not had any issues with it at all while reviewing this device. Everything’s been super smooth and quick responding. But that’s what you get when you stick to a relatively vanilla approach to Android. Something we wish more smartphone makers did.
To wrap up the software section, it’s important to talk about updates. According to Motorola, they are promising three OS updates. Which means this will get Android 14, 15 and 16. As well as 4 years of security updates. That does put them in line with most other OEMs, and a big departure from its previous stance of maybe updating their phones to the next version of Android. So good on Motorola there.
Flex View mode is incredible
Flex View is nothing new for foldables. Samsung was the first to do this, back on the original Flip, and others have added this feature as well. But basically, on the Razr+, Flex View is great for using with the camera. When you take a photo, the front-display will automatically show the viewfinder, even if you are not in Flex View mode. If the phone is flat, it’ll still show the viewfinder. So those you’re taking photos of, can see how they look. You can also use this when closed, so the front-facing camera is pretty much pointless.
There’s more that the camera can do in Flex View mode as well, like the ability to take multiple photos back to back, like a photo booth. You can also take photos hands free, and the viewfinder will take up the top half of the display, while the controls take up the bottom half.
It also works in a few other apps like, YouTube. Which will show the video in the upper half of the screen, with all the controls at the bottom. But most of the Flex View features are in the camera app, currently.
Motorola Razr+ Review: Camera
The cameras on the Motorola Razr+ aren’t the most feature-rich, and they aren’t going to be the best cameras on a smartphone. We kind of expect that from Motorola these days. But they will get the job done. The cameras are actually pretty good, though some of its non-folding competitors will perform better – like the Galaxy S23 Ultra and Pixel 7 Pro.
On the Razr+, we have a 13-megapixel ultrawide sensor, and a 12-megapixel main sensor. The main sensor is fairly large at 1.4um, in fact, those are larger pixels than what the Pixel 7 Pro uses. This means that Motorola’s camera can let in more light. So even though it is only a 12-megapixel shooter, it does provide some really great looking photos.
In my testing of the Razr+, I found that the colors were pretty accurate, and not saturated at all. So that’s a win over the Galaxy S23 Ultra already. It was also able to take photos of my dog that didn’t get super blurry. Typically, her face becomes blurry on any non-Pixel smartphone. Due to her being black and not staying still for more than a fraction of a second. So that means that the focus is accurate and the shutter is fast. That’s always a good thing.
Macro mode done right
Motorola has often times been an offender of adding a dedicated macro sensor that was just complete trash. Usually a 2MP or 5MP macro sensor, just to be able to say there’s two or three sensors on the phone. But with the Razr+, Motorola decided to use the ultrawide for Macro. What they call “Macro Vision”. This is the new trend as of late, and it works out really well. I was able to get up pretty close to a number of objects and get some really good macro shots.
Macro mostly works better on trees, signs and plants outside. That is because of the natural sunlight. Remember when you are that close to something, you’re also blocking the light. Making it tough to get enough light to get a good picture. I took a few pictures at my desk, and they didn’t come out quite as nice.
Here’s a few samples of the macro shots I was able to get.
Portrait mode on the other hand, is also fairly good. It’s not perfect, especially on objects. Like with a lot of other phones, portrait mode works better on humans than objects. But I was still pretty impressed with it. Motorola might take the second best portrait mode photos behind the Pixel.
Should you buy the Motorola Razr+?
The big question here is, whether you should buy the Motorola Razr+? I really want to say yes. But a foldable is not for everyone. Even for myself, I’m not sure I could live with this phone for two, three years, before it’s time to upgrade again. And that’s not to say it’s a bad phone, it’s quite the opposite. I just don’t know if I’m ready for having to open my phone hundreds of times a day to do things.
However, if you are looking to get a foldable, this might be the one to get. And there are plenty of great deals available right now, where you can get it for nothing, or very little money. If you want something a bit cheaper, the Razr will be launching in a few months, with an even lower price tag.
The threat actor “Midnight Blizzard” is engaging in increasing credential attack activity.
They conceal the origin of their assaults by employing residential proxy services.
These attacks target governments, IT service providers, NGOs, the defense sector, and vital manufacturing.
Numerous password spray, brute force, and token theft tactics are used in these credential assaults.
Microsoft has detected increased credential attack activity by the threat actor Midnight Blizzard using residential proxy services to obfuscate the source of their attacks. These attacks target governments, IT service providers, NGOs, defense industry, and critical manufacturing.
— Microsoft Threat Intelligence (@MsftSecIntel) June 21, 2023
Employing Low-Reputation IP Addresses & Proxy Services
Midnight Blizzard (NOBELIUM) has also carried out session replay assaults using stolen sessions, most likely obtained through illegal selling to get initial access to cloud resources.
Threat actors’ connections made with compromised credentials can be obscured by utilizing low-reputation IP addresses, such as those provided by residential proxy providers.
Microsoft Threat Intelligence reported that “the threat actor likely used these IP addresses for very short periods, which could make scoping and remediation challenging.”
Details of Midnight Blizzard Threat Actor (Microsoft)
Microsoft noted in a series of tweets that, making issues even more difficult, the threat actor only uses these IP addresses occasionally, creating substantial obstacles for effective scoping and remediation operations.
It is important to note that the same organization, known as Midnight Blizzard or NOBELIUM, was responsible for the disastrous SolarWinds breach in late 2021.
Microsoft has strengthened its defenses to combat this growing danger. To defend against these attacks, Microsoft Defender Antivirus, Defender for Endpoint, Defender for Cloud Apps, and Azure Active Directory have all been given strong security features and improved detection capabilities.

US military personnel have become unsuspecting recipients of unsolicited smartwatches delivered straight to their mailboxes. Recent reports indicate that these seemingly innocuous devices, once activated, automatically connect to Wi-Fi networks and establish unauthorized connections with users’ cell phones, potentially exposing sensitive personal data.
It has been discovered that these smartwatches are not only capable of accessing a vast array of user information but may also contain malicious software, including malware. This was revealed on June 15th, 2023, by the Department of the Army Criminal Investigation Division in a press release.
This malicious software grants the sender unrestricted access to saved data, including but not limited to banking information, contacts, and account details such as usernames and passwords. The consequences of such breaches could be far-reaching, compromising not only personal privacy but also financial security.
Moreover, security experts have warned that the embedded malware might enable unauthorized individuals to remotely exploit the smartwatches’ voice and camera functionalities.
This would grant malicious actors the ability to monitor private conversations and gain unauthorized access to online accounts tied to these devices, further exacerbating the potential risks faced by the affected military personnel.
This incident is somewhat similar to the one in March 2020, in which malware-infected USBs were sent with unsolicited Best Buy gift cards. According to researchers, the USB drives contained an Arduino microcontroller ATMEGA32U4 and were infected with GRIFFON malware.
The unsettling discovery has raised concerns among military officials, prompting investigations into the origins and intentions of these unsolicited smartwatches. While the exact motives remain unclear, experts suspect that these devices might be part of a larger scheme known as “Brushing.”
This deceptive practice involves sending counterfeit products to unsuspecting individuals in order to generate positive reviews under their names, enabling unscrupulous companies to compete with established products.
To combat this growing threat, military personnel who receive these unsolicited smartwatches are urged to exercise caution and follow specific protocols. First and foremost, recipients are strongly advised not to turn on the device under any circumstances. Instead, they should promptly report the incident to their local counterintelligence or security manager.
Additionally, individuals can utilize dedicated reporting channels such as the “Submit a Tip – Report a Crime” portal to ensure swift action is taken to mitigate the risks posed by these rogue smartwatches.
As investigations continue, it is crucial for military personnel and the wider public to remain vigilant against potential cybersecurity threats and promptly report any suspicious activities. By raising awareness about this issue, steps can be taken to safeguard personal privacy, financial well-being, and national security.
In the face of these emerging challenges, it is imperative for authorities, technology companies, and individuals alike to work together to stay one step ahead of those who seek to exploit our vulnerabilities in the digital realm.
Privacy-focused messaging app Signal is adding text formatting. You can italicize your message, make it bold, strike through a word or phrase to discard it, share code in monospace, or use a spoiler effect to hide your message from the recipient (more about it below). These formatting options are currently available to beta users. A stable release may follow in the coming weeks.
The latest beta update for Signal brings text formatting
Signal has made itself a name in the messaging space thanks to its extensive privacy features. The app regularly adds new features, such as camouflage icons, to further bolster its privacy-centric approach. However, it still lacks in some other areas. Text formatting has been one of the missing features, and it’s now on the way.
Version 6.24.1 of the Signal beta for Android lets you format your message in various ways before sending it. You can format a single word or the whole message by selecting it in the compose field (press and hold on to a word). This will bring a pop-up menu with multiple action buttons, including Cut and Copy. Next to those are formatting options, such as Bold, Italic, Strikethrough, Monospace, and Spoiler (tap the vertical three dots to see more).
Most of you may be already familiar with these options, or at least the former three. Bold will make the selected word/phrase bolder to emphasize it, while Italic will italicize the text. Strikethrough puts a line through the text to make it look like you have discarded it without erasing the text. Monospace, meanwhile, is usually used to separate codes or other technical information from the main text. In this format, all characters have the same breadth.
Finally, Signal has added a Spoiler effect that hides the message with an animation. The recipient can choose to see it by tapping on the message bubble, but the message will not show up until they manually opt to see it. This can be handy in group chats where you don’t want to reveal the plot of a new movie to a friend who hasn’t watched it yet but want to discuss it with others who have watched the movie.
As said earlier, these text formatting options are rolling out with version 6.24.1 of Signal beta for Android. If you are part of the beta program, check for an update for the app in the Google Play Store. If not, you can join the beta program here. Those who are not willing to use the beta build will have to wait until these features arrive in the stable channel. You can click the button below to install the latest version of the Signal app.
The iPhone SE 4 info has been all over the place for over half a year at this point. The latest piece of information claims that the iPhone SE 4 is coming, but that its launch got delayed again.
The iPhone SE 4 launch gets delayed yet again, unsurprisingly
Barclays analysts said, to MacRumors, that the phone’s 2024 launch window is “unlikely”. They say that the reason for that is Apple’s in-house 5G modem. That modem was supposed to debut inside the iPhone SE 4, and it still is, hence the delay.
As some of you may know, Apple acquired Intel’s 5G modem division back in 2019. At some point since then, Apple has been trying to produce its own 5G modem, but things don’t seem to be proceeding as expected.
Apple most likely acquired Intel’s 5G modem division due to a public clash it had with Qualcomm back then. Qualcomm accused Apple of patent infringement. That has been settled a long time ago, but Apple is still working on its own 5G modems.
The rumors have been all over the place, to put it mildly
In any case, at the beginning of the article, I said that the iPhone SE 4 rumors have been all over the place. That could not be more true. Back in December last year, a report surfaced claiming that the iPhone SE 4 is not coming at all.
Then, in February, a follow-up came, saying that the device will launch, but in 2024. After that, 2025 was mentioned as the launch year, and the latest rumor before this one claimed that the iPhone SE 4 is just a prototype for 5G modem testing, and that it’s not coming.
Saying that the rumors are all over the place is an understatement. If you decide to put faith in the latest one, the one we’re talking about today, the iPhone SE 4 will become a reality, but not until 2025.
The iPhone SE 3 launched with a very affordable price tag, but it came with a number of compromises, ranging from its dated design, to very poor battery life, to camera performance.
With the iPhone SE 4, if it ever sees the light of day, Apple will update the design. It will no longer use the iPhone 8 chassis.
Researchers have devised a new attack strategy to exfiltrate sensitive information from target devices without physical access. The attack methodology presents video-based cryptanalysis, where an attacker may extract the cryptographic keys of target devices from the video footage of their power LED indicators.
Extracting Cryptographic Keys Via Power LED Videos
According to a recent study, it is possible for an adversary to extract the cryptographic keys of a target device merely by analyzing video footage of the device with its power LED visible in it.
Specifically, this video-based cryptanalysis technique relies on detecting the change in power LED light’s brightness. As the CPU performs cryptographic computations, the subsequent power consumption impacts the brightness of the LED lights.
While these brightness fluctuations seem harmless, a smart attacker can detect and analyze the changes to retrieve secret keys. An attacker may simply record the video of the target device, focusing on the power LED. Then, zooming in the video to fill the frame with the power LED allows exploiting the rolling shutter to increase the sampling rate of the LED color by three magnitudes. Next, analyzing the video frames in the RGB space empowers the adversary to decipher the RGB values and retrieve the secret keys.
In their study, the researchers demonstrated two side-channel cryptanalytic timing attacks. First, they extracted the 256-bit ECDSA key of the target smart card by recording and analyzing the video footage of the smart card reader power LED, obtained from a distant (16 meters away) security camera. (Dubbed as the “Minerva” attack.)
Next, they demonstrated a similar attack on a Samsung Galaxy S8 by exploiting the power LED of a Logitech Z120 USB speaker connected to the same USB Hub as that of the Galaxy S8. The researchers recorded the speaker’s power LED via an iPhone 13 Pro Max. (Dubbed as the “HertzBleed” attack.)
The researchers from the Ben-Gurion University of the Negev, Israel, have shared the following video to demonstrate the attack. Besides, they have described their study in detail in their research paper.
Suggested Countermeasures
The researchers explained that the vulnerabilities exploited in this attack don’t exist in the power LED or other device hardware. Instead, the flaws exist in the existing cryptographic libraries. They found at least six smartcard readers from five different vendors and Samsung Galaxy S8 vulnerable to the demonstrated attacks.
Although, the researchers advise using the most updated cryptographic libraries to prevent the vulnerabilities. However, they do not rule out the possible zero-day flaws in the latest libraries that may facilitate such attacks.
Therefore, the basic prevention against Hertzbleed and Minerva attacks is having no power LEDs in the device. Nonetheless, such attacks are still possible by detecting the power LED of connected peripherals (as demonstrated in the case of Samsung Galaxy S8).

Amidst economic hurdles, 2023 has been the year where almost every company has laid off a significant portion of their workflow. Now, in a recent development, Qualcomm has announced significant job cuts as it aims to reduce expenses in light of a persistent slowdown in smartphone sales.
As per the Worker Adjustment and Retraining Notification Act (WARN) paperwork, the company has not only eliminated 415 positions at its San Diego headquarters but also let go of 84 employees at the Bay Area office. Amongst the layoffs, the engineering department was the most affected, with approximately 300 positions eliminated, as indicated by the WARN notice.
Reasoning for the layoffs
While smartphone and modem sales in the US have remained consistent, soft smartphone sales, particularly in China, have had a substantial impact on Qualcomm’s growth this year. During the latest earnings conference call in May, Qualcomm’s CEO, Cristiano Amon, acknowledged the challenges and stated, “We are actively managing operating expenses and will continue to evaluate additional opportunities to drive greater operating efficiencies without losing sight of the automotive and Internet of Things growth opportunities ahead.”
However, it is important to note that this new round of job cuts comes in addition to two smaller layoffs that Qualcomm announced in December and March, resulting in a total of 232 workers being removed from the San Diego workforce.
Venturing into new areas
Although Qualcomm’s revenue has been slowing amidst economic hurdles, the company has been working on expanding its business, particularly in the automotive industry, where they are focusing on in-vehicle connectivity, digital dashboard/infotainment systems, and autonomous driving technologies. Additionally, the company is also ramping up its efforts to supply technologies for various industries, including in-cabin cameras for trucks, drones, retail and warehouse scanners, and robotics.
“We are on track to meet our commitment of a 5% reduction in non-GAAP operating expenses relative to our fiscal ’22 exit rate. This includes a further reduction of spending in handsets to fund diversification investments,” said Akash Palkhiwala, chief financial officer, at a recent earnings call.
