This is a common complaint from some, on all Roku models. Others have no problem with this at all (I seem to be one of the lucky ones.)
If you have one of the remotes that has an earphone jack for remote listening, the earphone amplifier in the remote is activated and more quickly draining batteries whenever something is plugged into the jack, even when you are not streaming anything. Make sure you unplug the phones when not actively listening.
There also is some anecdotal evidence that battery life can be affected for those with point-anywhere remotes that connect to the Roku via WiFi-direct. The remote has to work too hard constantly sorting through the information packets from other devices using the same channel and it uses up the batteries much too quickly.
If you have access to your router's setup, try configuring it to use a different WiFi channel to see if this helps the situation. In the 2.4 GHz band, channels 1-11 are supported. Channels 1, 6, and 11 do not overlap each other and so give you the best chance at reducing congestion, so try each in succession, although depending on what channels your neighbors are using other channels in the 1-11 range may work best. Also, reducing router bandwidth from 40 to 20 kHz may also reduce interference.
Please report back to let us know how you make out.
