Nest Thermostat Batteries LOW on a new ORBI AX setup

No. 

Only thing I found was that with mine, being so close to the RBR, 5 feet, was having problems with the NEST. I found that when I moved the RBR away from the one NEST controller, 20-25 feet, the NEST controller started working with out draining the battery. Also was said that this is also a NEST controller issue as well that NEST needs to fix it on there side as these controllers ping pong back and forth on there own when there is more than 1 signal source in play, i.e. RBR and 1 or 2 RBS. Its also recommemeded to install the C power wire to your NEST from the main central AC system to help avoid the battery draining. You'll need to consult your systems mfr wiring diagram to find out which connection that is.
