Anyone that's been up a mountain recently will know the anxiety of taking your phone out after a few great runs to find it worryingly freezing and inexplicably low on battery. That's because modern smartphones aren't anywhere near hardy enough for seriously cold temperatures, and battery life takes a serious hit as a result.
You might think you need a waterproof phone case to go skiing. What you actually need is something to keep your phone warm because – as all skiers and snowboarders know – freezing conditions can massively reduce the battery life of a fully-charged phone. Cue Phoozy’s Apollo II BlackOut Plus (US$30/UK£33, about AU$60), which is designed for an inner jacket pocket or a pocket on salopettes.
