The Janus One is a small, simple, and stylish phone with up to 90 days of stand-by time15
Enter the Janus One. This project wants to simplify your life “in a smart way.” The Janus One is a connected dialer for your smartphone, or it can be a standalone, fully functional feature phone.
Underneath the stylish exterior, the Janus One can work as a battery back-up for your smartphone, a pedometer, and more. Perhaps the most impressive part of the Janus One is the claimed 90 days of stand-by time thanks to a large-for-its-size 1,500mAh battery. That is quite a feat given the credit card sized frame, and being only 5.5-mm thin. It also happens to be water resistant.
Using it as a Bluetooth connected companion to your smartphone, the Janus One will work as a remote dialer, or you can even get better than half of a full charge on an iPhone 6.
The Janus One is an unlocked GSM phone that accepts a micro SIM card. It will also store up to 500 numbers, and handle SMS messaging. It will be available in three colors, black, white, or gold. You can reserve yours on Kickstarter for $69 which includes shipping (there are volume discount perks as well), and the China-based team has an ambitious September 2015 ship-date. Details can be found through the source link below.
