Stranded on the road or caught in a power cut? Emergency mode gives 1 hour of non-stop heat.
Keep your coffee warm
Rest the cup on your phone and let the first sip's warmth last to the last.
Stay warm, always
Warm hands, warm coffee, warm soul. Your phone runs a little hot, but it does it for you.
How it works
- 1
Pick a target between 30 and 55 °C on the round dial and tap start.
- 2
All processor cores and the graphics chip get to work and the screen glows brighter. Once the target is reached, the load drops to hold the warmth.
- 3
Built-in protection: the load backs off by itself when the device gets too hot, and on iPhone the heat is held at 40 °C.
