That seems incredible to me. The Moto 360 review at The Verge mentioned that at best it barely got through the day, and that was with the display off most of the time like the Apple Watch. They've improved that much since then?
Yep, there were several Android Wear updates which really made a big difference in power usage. I suspect they included better use of BTLE, and a dimmer always-on mode for most of them, which then goes bright when you twist your wrist/ click the button. (The LG Watch R is a beautiful exception to that. It's always bright.)
Now, you'd think that because web reviews are electronic, that they could be easily updated to reflect stuff like this, but few of today's "reporters" ever do updates or corrections.
So most of the Moto 360 reviews I've seen, still give battery life from the way it was back in September.
What's the difference between the LG Watch R and the Apple Watch that allows for 49 hours of always on use?
Forty-nine hours was my result. It didn't include any music playing. So subtract that out.
As for hardware, I only know the difference between the LGWR and the Moto 360, which explains why the LGWR does so much better than the M360:
- M360 - 320 mAh battery, LCD display, and older TI OMAP CPU
- LGWR - 410 mAh battery, P-OLED display, and Snapdragon CPU
Also, remember that the Apple Watch will go a total of 72 hours if you shut most stuff down.
