Apple is facing another lawsuit over Powerbeats battery trouble. New York resident Alejandro Vivar has filed a potential class action lawsuit over allegations Powerbeats Pro design defects prevents the wireless earbuds from charging properly. As it's reportedly too easy to lose contact between the buds and their charging case, one of the earpieces either won't charge "consistently" or quickly drain its charge. Apple committed fraud by misrepresenting battery life and failing to address issues it supposedly knew about, the plaintiff said. Vivar's attorneys suggest a combination of the case design and an insufficiently sturdy ear "gasket" (the piece that goes into your ear) may be responsible. Customers have had to resort to inserting a "wedge" to keep the charging pins in contact, according to the lawsuit. The lawyers also reject Apple's claims the Powerbeats Pro are sweat- and water-resistant, arguing that sweat corrodes the charging conta...

This SAD lamp makes the winter almost bearable

Gather ‘round and let me tell you a story about the dark sky that makes mid-afternoon feel like midnight, and the light source that makes it at all bearable. Once a year, winter appears with a quick chill of the ears and sudden craving for a vat of hot chocolate. It brings all things beautiful: holiday lights, white blankets of snow in the park and thoughtful gifts. But it also invites in the cold and heaping amounts of darkness. I came of age in upstate New York, where sunlight is gone by half past four in the afternoon the entirety of December and January. That’s to say this isn’t a new phenomenon for me, but that hasn’t made it any less painful. In fact, it has caused a feeling of dread that starts popping up come late September. But when I moved to Scotland, 4:30PM became nearly 3PM and the sun didn’t fully rise until well after I’d woken up. Even in London where I’m now based, it’s easily dark by 4PM on the shortest days. Like most people, the darkness leaves me exhausted while...
