The Morning After: Does Samsung have another phone-battery problem?

Amr Dalsh / reuters

A few years ago, Samsung had major battery issues when several faulty Galaxy Note 7 phones had exploding batteries. The devices were recalled, and the company spent a lot of time over the following years outlining all the rigorous battery tests it did to ensure it didn’t happen again.

Now, YouTuber Mrwhosetheboss, as well as others, have noticed batteries in Samsung phones are swelling up at a disproportionately high rate. This usually affects older devices, but some are only a couple of years old – the 2020-era Galaxy Z Fold 2, for instance.

Samsung hasn’t formally responded yet, but battery swelling isn’t a new problem, nor one unique to Galaxy phones. As lithium batteries age, their increasingly flawed chemical reactions can produce gas that inflates battery cells. Many companies suggest you keep device batteries at a roughly 50 percent charge if you won’t use it for extended periods.

The latest iPadOS 16 beta brings Stage Manager to older iPad Pro models

An M1 chip is no longer required, with a caveat.

The biggest change with iPadOS 16 may be Stage Manager, a totally new multitasking system that adds overlapping, resizable windows to the iPad. The latest iPadOS 16 developer beta can run Stage Manager on several older devices: It’ll work on the 11-inch iPad Pro (first generation and later) and the 12.9-inch iPad Pro (third generation and later). However, there is one notable missing feature for the older iPad Pro models – Stage Manager will only work on the iPad’s built-in display. You won’t be able to extend your display to an external monitor.

Intel’s 13th-gen CPUs offer up to 24 cores and 5.8GHz speeds

The Core i9-13900K sounds like a beast.

Intel’s 13th-gen Core chips, AKA Raptor Lake, have landed. The company’s new top-end chip, the Core i9-13900K, sports 24 cores (eight performance cores and 16 efficiency cores) and can reach up to a 5.8GHz Max Turbo frequency. Last year’s i9-12900K offered 16 cores and a maximum speed of 5.2 GHz. Intel claims the new 13900K is 41 percent better for multi-threaded work, like video encoding. If you skipped last year’s chips or are running even older Intel hardware, the 13th-gen CPUs look like the update you’ve been waiting for.

Volvo has developed the world’s first interior radar system for cars

It’s a new safety feature.

Set to debut on its upcoming flagship EX90 electric SUV, Volvo’s new radar system monitors both the cabin and trunk, to prevent a car from being locked while anyone is inside. The idea is to guard against situations where pets or children may be inadvertently trapped inside a car on a hot day, with the car surfacing reminders if it recognizes there are occupants inside when being locked. Volvo says the multiple radars in the trunk, in the car’s overhead console and in roof-mounted reading lamps can detect “sub-millimeter” movements.
