I have the Moto 360 gen 2 that I use daily paired to the 10. Since I am not allowed to have my phone out at work I use the watch for notifications and such. I stream music all day (10 hours) from my phone using my watch to control volume and change songs to my Bluetooth speaker. Text messages I respond to by voice. Music is streamed from local storage.
When I leave work my phone and watch are at 100 percent and when I get home 11 hours later my watch and phone are down to around 65% remaining. I have done this for weeks now and that is average. I have very little screen on time on the phone and there is no wifi at all. I don't shut off wifi. The watch is always on using full ambient mode. The few days that I forgot my speaker and did not stream, my phone is down to 85% and my watch is still drops to about 65%.
My coworker has the Huawei watch and he gets about the same battery usage on the watch but has ambient mode disabled. He pairs to an S7 and does not stream. At first his watch would only last a few hours, but over time the power consumption stabilized and he gets a full day.
