Samsung’s Galaxy Z TriFold settles for 15W wireless charging — here’s why

[phillynews215]

TL;DR

• Samsung’s new tri-fold prioritizes thinness through custom engineering, measuring just 3.9mm when unfolded.
• A special slimmed-down wireless charging coil from partner Witz was essential for this ultra-thin design.
• It’s “Qi2 Ready,” but requires a special magnetic case for accessories, as it has no built-in magnets.

Foldables have always fought a war on two fronts: You want a massive screen, but you don’t want a brick in your pocket. With the new Galaxy Z TriFold, Samsung has managed to keep the phone slim, measuring only 12.9mm thick when folded and just 3.9mm when open. Achieving this slim design required impressive engineering, especially when it came to powering the device without needing to plug it in.
