Fitbit Edge Leak Points to Replaceable Battery With 7-Day Life

Leaked retail listings say Google's unannounced Fitbit Edge will have a user-replaceable lithium-ion battery lasting up to seven days, or two days with the 1.34-inch always-on OLED display, where pixels emit their own light, left on. The same leak lists IP68 water resistance, meaning dust-tight and able to survive submersion.
