Ok, is not a battery matter. To turn off the recording lights and bluetooth (did´t tried with the peak one), , all you have to do is Menu/ 7 Display/ Indicator>>POWER SAVE.
After 10 seconds, ALL the lights are off.
If you use remote control, you will have only the bluetooth blue one, then, after 10 seconds (or the time you choose to turn off the screen in the R07) will turn off, and when you press record in the app, there is no lights.
