Proprietary vs. Common Batteries Most cameras now require a certain style of battery for a particular camera. Battery styles vary by both manufacturer and camera model. Search for “Nikon battery” or “Canon battery” on the internet, and you’ll find many different shapes of batteries even within that manufacturer’s product line. Some types are for point-and-shoot cameras, while others are for DSLR cameras. Fortunately, most DSLR cameras by one manufacturer use the same style of battery....

Initially spotted by WABetaInfo, the app is working on privacy tools that would put you in more control of who sees your status. With the new customizable feature, you would be able to choose “Everyone,” “Nobody,” “My Contacts,” and now, “My Contacts Except” for your Last Seen. The option to choose who sees what aspects of your WhatsApp profile will go beyond the Last Seen feature and include your Profile Picture and your About, which contains things like your bio....

All iPhone models are relatively similar when it comes to hardware. It’s the software that’s different. Apple releases a user guide that covers all models that can run the latest operating system every time a major new version of iOS comes out. Apple produces other instructional materials, such as product and safety information and QuickStart user guides, for each model. Identify which model you have below, and then download the user guide you need....

How Horn Speakers Differ From Modern Speakers Horn speakers are much larger than their modern counterparts. For example, some vintage Altec Lansing speakers stand four feet high and three feet wide with an imposing multicellular horn perched on top. Because they were designed to run on low-power amplifiers, they are energy-efficient despite their size. Horn speakers come in different designs. For example, Altec offered several different cabinets, including the A5 and the A7....

You may have thought that Apple’s War on Buttons ended when Joni Ive split, but it seems to be lumbering on. According to well-sourced analyst Ming-Chi Kuo, the iPhone 15 may ditch its remaining physical volume and power switches in favor of touch controls with haptic feedback. This could possibly make the iPhone more durable, but it could also make it a lot more annoying. “Its decision to remove the physical home button with a haptic engine was in the right direction, and time has proved it....

A recent update on Oculus’ development blog revealed plans for multi-user accounts and app sharing—two of the biggest features the virtual reality community has been asking for. While the idea of app sharing might not seem that important to the overall future of VR, some believe it will be a vital step in helping to expand the number of people who enjoy VR content. This could then lead to more purchases of Oculus VR devices in the future, especially as the company continues to update and expand the app sharing system....

Why is it so good? Because the biggest iPad not only excels in everything that makes smaller iPads great, it also has a surprising number of other capabilities only possible with the bigger screen. I love my big iPad, and while I sometimes get jealous of the cute 11-incher, the 12.9 is the best all the way. Love At First Sight The first iPad launched in the US back in 2010, and I had a friend buy one and ship it to me in Europe because I couldn’t wait four months to get my hands on it....

“The Scribe is a huge deal because of its modern features that make the classic Kindle attractive to younger generations as well as older generations,” Troy Portillo, director of operations at online learning platform Studypool, told Lifewire via email. “It’s good for students, writers, researchers, and historians alike. The Kindle Scribe is perfect for users who like to take notes and annotate what they read. I’m excited to get my hands on one!...

The new M2 MacBook Air is thin, light, has battery life for hours, and comes in at only a few hundred dollars more than the iPhone. And that’s because it kind of is a big iPhone, which is exactly the computer we’ve been waiting for all these years. “In my opinion, 14- and 16-inch MacBook Pros with M1 Pro and Max were the very first true laptops in the mobile era....

Start saving now because an AirCar, which can drive on roads while also being able to fly, recently completed a 35-minute test flight. A new study found that the cost of a flying car will come in at over $700,000. “Individual, middle-class people may not be able to afford to buy a flying car in the near future or until as early as 2050,” Seongkyu Lee, a professor of aerospace engineering at the University of California, Davis, told Lifewire in an email interview....

Playing video games in VR can cause time to seem compressed, according to new research. The study found that participants who played the virtual reality version of a game first played for an average of 72.6 seconds longer before feeling that five minutes had passed than students who started on a conventional monitor. “Research suggests that perception depends on bodily signals such as our heart rate,” Nick Davidenko, a scientist at the University of Santa Cruz and one of the study’s authors, said in an email interview....

Home Depot is piloting a program that requires tools to be activated by Bluetooth before you can use them. The program is meant to deter theft, but experts say it’s a sign of the increasingly blurry definition of ownership in the digital age. “The bigger question is what downstream software update may turn the once-owned power drill into the newly leased power drill, which throttles features, functions, benefits, digital obsolescence, and your private data,” David Forman, a vice president at cybersecurity firm Coalfire, told Lifewire in an email interview....

OLED displays are superior to the LCDs in most laptops, but short battery life and high pricing have kept them out of small, portable PCs. Dell’s latest XPS 13 could change that. It has a 3,456 x 2,160 OLED and promises a contrast ratio of 100,000:1, nearly a hundred times better than a typical LCD laptop display. This isn’t Dell’s first go at OLED. Alienware, which Dell owns, introduced a short-lived OLED variant of the Alienware 13....

Of course, that information doesn’t help those folks who might need to buy a new vehicle. A single-car family with a car that’s been in a collision or is beyond repair can’t wait 12 months (or longer) for the market to settle itself. They’ve been eyeing an EV, and now they figure if they have to buy something new, it might as well be powered by electrons instead of fossil fuels....

You’ve always been able to share app purchases, but now anything you pay for inside an app also can be shared, including subscriptions. IAP-sharing joins all the other Family Sharing services, like iCloud storage, TV and Arcade subscriptions, and Apple News+. This is a big deal, and can potentially save you a ton of money. But what about the developers? Aren’t they going to be out of pocket? James Abeler, founder and director of Firecore, which makes the excellent video-playing app, Infuse, thinks not....

Virtualization is usually considered too geeky a process for average desktop users, but all it takes is a single click to install Windows 11 on top of the new Parallels Desktop 18. With a significantly improved performance, and the ability to work with Xbox and PlayStation controllers for playing Windows-only games, initial reviews on Twitter seem to suggest Apple Silicon Macs are the best Windows PC, though the experts aren’t buying any of it....

Cybersecurity researchers at Rezilion recently discovered over 90,000 vulnerable internet-facing applications, including over 68,000 potentially vulnerable Minecraft servers whose admins haven’t yet applied the security patches, exposing them and their users to cyberattacks. And there’s little you can do about it. “Unfortunately, log4j will haunt us internet users for quite a while,” Harman Singh, Director at cybersecurity service provider Cyphere, told Lifewire over email. “As this issue is exploited from server-side, [people] can’t do much to avoid the impact of a server compromise....

Yet this is exactly what our mobile carriers have been doing. Thanks to responses published by the Federal Communications Commission (FCC), we now know that not only are some of the country’s top telecom operators, including AT&T, T-Mobile, US Cellular, Verizon, and others, privy to our phone’s location information, many hold on to this, and other, rather private data, for years on end. “Our mobile phones know a lot about us,” FCC Chairwoman Jessica Rosenworcel said in the press release about the responses....

The announcement, made on YouTube’s news blog and reported by CNET, explains how the new features will “help people more easily search and find content on YouTube.” The first change is allowing users to get a preview of the video they’re about to watch on the YouTube mobile app. A video creator can add time-stamped images that list out the different topics covered in their video and allow users to determine if it’s of interest....

Whether you use YouTube in a browser or on your phone, things are going to start looking a little different in the near future—especially if you prefer to use the dark theme. The darks are getting darker to bump up the contrast and make colors and brighter tones pop just a bit more, while video and playlist pages will be adding a little dynamic color. This “ambient mode,” as YouTube calls it, dynamically samples color from the video and adds similar shades to the background of the video or playlist page....
