What do you guys think about battery life of the LG G Watch R after the 5.1.1 update? I got the update on Monday and since then I noticed that I would only get about 30h out of the GWR. Before the update I could wear it for 2 days (>50h) without problems. I didn't change my habits, nor did I install a ton of new apps.

I think I am going to factory reset the watch and see if it goes back to normal. Did any of you experience something similar? Btw I have had Google Fit deactivated since I got the watch. I am using tilt to wake and the new gestures! I'm on always on and brightness is at maximum.

Thanks for all your comments!

Performance optimizations of the demodulation code of RF Analyzer
When I started implementing AM and FM demodulation for the RF Analyzer, I first built a receiver in GNU Radio Companion and then tried to rebuild it in Java. The basic blocks in the receiver are pretty simple and soon I had working code. But I had to recogn...
