## Questions & Answers

**Q: How long is the battery life?**
A: I use my 44mm with everything always on, including the display, and mine goes about 40 hours. Turning the display to turn on only when you turn your wrist takes into 60 hour territory.

Turning off sensors and radios doesn't do much good as it keeps the system from optimizing properly. To get best battery life, let the watch manage the sensors and radios.

**Q: Are all of the warch faces silly like in the pictures?**
A: Their are thousands of watch faces on the play store that you can download to your watch. I do not recommend Facer. Facer's watch faces drain the battery on the watch plus you must run the Facer app to use the watch faces.

**Q: Im wondering if this watxh will allow you to make and recive phone calls and texts? And if you have to have a premuim paid servuce like fitbit**
A: No only can you make and answer calls when your phone is near the watch on blue tooth. You can set the remote mode on, put your wifi on and leave it on and if you go over to a friends house you can connect the GW4 watch to their wifi and receive and make calls with your phone at home.

**Q: Can I get emails on this watch?**
A: I get 25+ emails/texts on my watch per day on weekdays and the drain on the battery is minimal.
