Why smartphone batteries explode, and why they may get worse

When I started at The Verge in 2014, I needed an excuse to learn about technology. My background was in covering video games, television, and pop culture, and I lacked the basic cognitive functions to hold a phone above my head without dropping it on my face. So I launched a podcast called What’s Tech. For two years, the show was an opportunity to learn the fundamentals about the technology that supports everyday life. Free to ask silly, obvious, and embarrassing questions, I learned a ton. I hope you did, too. After all, my favorite takeaway from the podcast was that I wasn’t alone. We often take tech for granted, like a magical apparatus that does everything we need, not a massive collection of moving parts designed and programmed by women and men with their own dreams, ambitions, and motives. Technology is immensely confusing, but understanding how it functions and who creates it is a worthwhile and rewarding pursuit. I sincerely hope that through this show, tech became more accessible and less mysterious, without losing its fun and that special power to fascinate us. Recently, I took on more responsibilities with our Culture team. I’d love for you to check out our work. Right now, I want to give the section and its writers the time and support they deserve. But to focus on Culture, I need to let What’s Tech go on indefinite hiatus. I won’t go so far as to say the show’s done forever. We’ll leave the RSS feed open, and hopefully we’ll have something new to take the show’s place in the coming months. Which is to say, I’d encourage you to stay subscribed. Now for the final episode. For my guest, I invited my buddy Ross Miller, with whom I co-launched The Verge’s TLDR section. We talk about life on the internet. And also, breakfast. I hope you enjoy. Thanks for listening.

Snapchat Spectacles, the mysterious and incredibly hyped hardware from Snap, Inc., have arrived. Vending machines for the video camera sunglasses are springing up around the country, first in California and Oklahoma, and who knows where else next. Verge senior reporter Bryan Bishop joined me this week to talk about his experience hunting down Spectacles and whether we’re all going to feel like olds wearing them.

In the early 2000s, the digital photography revolution made it possible for miniaturized camera hardware and image sensors to be packed into cell phones without adding a significant amount of weight. Then the iPhone was announced. As the smartphone war began, the camera became an important part of the ongoing spec race. Competitors tried to beat Apple in making an excellent camera (and app) that was easy to use — and it took until this year for that to start happening. Now, two-thirds of adults in the US own a smartphone. The average smartphone user takes at least 150 photos per month. Instagram has half a billion monthly users. Even if it’s just selfies or pictures of lunch — nothing has familiarized people with photography like smartphone cameras. It’s now a part of our everyday lives. I joined Chris on this week’s What’s Tech to talk about my first camera phones, why the newest smartphones have such equally excellent shooters, and where it all goes from here.

Over the past couple years web security has become a staple of the nightly news. The stories usually hinge on government leaks, foreign hackers, or web encryption. There’s menacing subtext that practically everything put online is vulnerable to “cyber attacks.” Though one might wonder what steps are being taken to protect not just the government and giant corporations, but you, the individual. What keeps you safe when you stumble your way into a Wikipedia hole or click a strange link sent from a friend? To find out, I invited my colleague Russell Brandom to talk about web security, and particularly HTTPS. As Russell explains, while your information isn’t necessarily less vulnerable, websites themselves are becoming safer. This is a dense topic, but fortunately Russell brought a helpful metaphor. It involves pie. Subscribe to What's Tech on iTunes, listen on Spotify, or subscribe via RSS. And be sure to follow us on Twitter.

Our most sacred and special task as human beings is to document our own existence with a single-minded dedication. That's why we have massive iCloud photo libraries, 15GB of video of that really cool Springsteen concert on our phones, Instagram accounts for ourselves, our pets, and our alter egos, and dusty yearbooks stacked up in our closets. The latest in this personal digital archive: personal GIFs. Apps like Boomerang, Motion Stills, Giphy, DSCO, and more help us make GIFs and other short, looping videos of life's most precious moments. And of course, of life's most 'grammable sammies. The Verge tech reporter and gadget blog queen Ashley Carman joined me (Kaitlyn Tiffany, your friendly Chris Plante stand-in) in the single-stall What's Tech recording booth this week to compare sweat mustaches and GIF-creation techniques. We had a nice conversation about art, technology, ourselves, and the utility of acronyms. If you tune in, you'll also learn a little something about the future of keepsakes! It's a good, emotional time. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Here at The Verge, we love Halloween and everything about it. Horror movies, non-horror seasonal movies, seasonal beverages, seasonal bots, this Pumpkin Guy, horrifying makeup tutorials, poop-shaped candy — bring it on. In particular, we love to be scared. It gives us a sweet little adrenaline burst to get us across the daunting dark tundra of November to April. This Hallo-season, senior entertainment reporter Bryan Bishop has embarked on a journey to find the most immersive, creative, and high-tech scares in all of Los Angeles. In a new series called "The Future of Fear," he's taking us all where we're too East Coast or too chicken to go. These aren't your grandma's haunted houses (although Bryan and I will both stan for the original Haunted Mansion at Disney World, may it live forever). I love Halloween so much I, Kaitlyn Tiffany took over the seat usually warmed by your friendly neighborhood What's Tech host Chris Plante. You can't tell from the audio, but I wore a blazer to the recording because I take Halloween very seriously! Bryan told me about all the terrible things he's subjected himself to this fall, and it was delightful even while it shook me to my core. Basically, it's a haunted house of a podcast and don't listen to it before bed. Learn more about your ad choices. Visit podcastchoices.com/adchoices

Samsung has officially recalled the Galaxy Note 7 worldwide, after more than 90 of the large smartphones in the US overheated due to defective batteries. Overheating is, in this case, an understatement, as some owners have claimed their smartphones outright exploded. Exploding lithium-ion batteries actually aren’t so uncommon. As my colleagues Angela Chen and Lauren Goode noted earlier this month, there are many ways for a lithium-ion battery to become dangerous, and they aren’t limited to any one smartphone or electronic device. “An exploding phone seems like a freak accident,” write Chen and Goode, “but the same chemical properties that make batteries work also make them likely to catch fire.” To learn more about the lithium-ion batteries, I invited The Verge’s science reporter Angela Chen to the show. We talk about how manufacturers are pushing the battery to its limit, and what alternatives we may see in the future. Subscribe to What's Tech on iTunes, listen on Spotify, or subscribe via RSS.

I didn’t take many selfies until I downloaded Snapchat. But like so many people I’ve fallen in love with lenses, the optional tools that make my face look like a dog or an emoji or an advertisement for junk food. Now, a day doesn’t go by that I don’t mug into my front-facing camera. The magic of lenses is how they erase the perception of the selfie as an act of narcissism — an insipid criticism that comes from a certain clump of people who feel the need to bash people for showing a fleck of confidence. Why didn’t I take selfies? I was too embarrassed. Anyway! I digress! I’m clearly fascinated by the popularity and power of lenses, so I invited my friend and colleague Ashley Carman to the show. We talk about the potential of the lens, and the possible future of a would-be gimmick that has birthed a broader pop culture trend.

Late last month, news broke of the exoplanet Proxima Centauri b. Orbiting the closest star to our Solar System, there’s a lot to love about Proxima b since it shares a few key traits with our own home planet. But before we start making intergalactic vacation plans, let’s pump the space-brakes: half the planet is locked in darkness, it’s pelted by radiation from close proximity to its sun, and the rock is 25 trillion miles away. Our current best option for sending a probe there involves a laser-propelled space-sail, which would reduce travel time from tens of thousands of years to 20. Which is to say, while potentially astonishing, even the best case scenario seems like a long-shot for our lifetime. To explain Proxima Centauri b, I invited my friend and colleague Loren Grush onto the show. This is, I think, the first episode in which we don’t talk about the Nic Cage film Knowing, so just keep that in mind. Subscribe to What's Tech on iTunes, listen on Spotify, or subscribe via RSS.
