I've charged every night ever since I got the s3, just like you... Why notHave an LTE TMobile Frontier and, after some initial messing around, it works fine. I'm not trying to use it to solve the national debt or launch nuclear missiles so my demands aren't unreasonable. Does have alittle lag but battery life is about the same. Of course I charge nightly - why not - so it's not a big deal. I just don't run out at 10 at night if I'm out and about.
I have to agree. I wonder if the amount of apps on the watch plays a factor in the performance of the watch?
Similarly, I noticed that resetting my watch sped up my phone. This became necessary after my G3 stopped communicating on bluetooth. This with Tizen 3.
