Hi, yesterday I received my fr945 and fully charged it. Okay, I played around a lot in the evening including some running route suggestions. In the morning i had 76 percent battery. Battery drain is really huge in non workout mode. At 11 o clock today after my workout i had 72 percent battery, now at 1 pm its only 69 percent. The only sensor which comes in addition to my predecessor fr935 is oxygen. Other settings including my own watchface arre pretty the same as on my old fr935. This isn't very impressive. Any suggestions?
