Samsung will launch its first tri-fold smartphone this year, but the brand hasn’t revealed its launch date yet. And while we await more information from Samsung about this smartphone, rumored to be called the Galaxy Z TriFold, a patent document published by KIPRIS revealed the tri-fold will pack three batteries. Since this is a tri-folding smartphone, it has three segments, …

A patent application published by KIPRIS a week ago reveals what might be the final design of Samsung’s upcoming tri-folding phone, the so-called Galaxy Z TriFold. It bears a strong resemblance to an expanded Galaxy Z Fold 7, but it’s clearly a vastly different device with a unique internal structure. Detailed sketches discovered by our colleagues at GalaxyClub reveal that …

Every night some 74,000 gallons (280,000 liters) of water are frozen at Norton Audubon Hospital in Louisville, Kentucky. The hospital used to get all of its air conditioning from a conventional system found in most U.S. buildings, but now 27 tanks of ice sustain a network of cold-water pipes keeping operating rooms at safe temperatures and patients comfortable. This type …

Genuine repair parts for the Pixel 10 series are now available on iFixit with some interesting differences. The Pixel 10 Pro screen is more expensive this year, which makes sense given that it’s a slightly better panel with increased brightness. There’s a small $7 price increase for the back glass, which is presumably due to the addition of Qi2 magnets.  The …

In science, there is a surprisingly long list of things we still haven’t exactly figured out yet but still use because they work. This unexpectedly has been the case for lithium-ion batteries—a power source for electric vehicles and various portable electronics—where scientists knew what the mechanism was but weren’t sure exactly how it worked. Fortunately, MIT scientists have found the …

At the heart of all lithium-ion batteries is a simple reaction: Lithium ions dissolved in an electrolyte solution “intercalate” or insert themselves into a solid electrode during battery discharge. When they de-intercalate and return to the electrolyte, the battery charges. This process happens thousands of times throughout the life of a battery. The amount of power that the battery can …

Apple’s AirPods have long been criticized for being some of the most unrepairable gadgets you can buy, and the new AirPods Pro 3 sadly keep that reputation alive. Like every portable electronic device, Apple’s earbuds also rely on lithium batteries that degrade after a couple of years, but the problem is that the company still insists on gluing them inside, …

Researchers have developed all-solid-state sodium batteries that retain performance down to subzero temperatures. Developed by researchers from the University of California, San Diego, the batteries could help replace lithium-based energy devices. Researchers also revealed that sodium is an inexpensive, plentiful, less-destructive alternative, but the all-solid-state batteries they create currently don’t work as well at room temperature.  They heated a metastable …
