A wide variety of factors must be considered when discussing battery consumption. How many recordings/live streams are occuring on the cameras? What is the signal strength like and how far away from your router/smarthub are the cameras located?
What does the signal strength icon show for these cameras? Are you using activity zones? Has anything changed with your network recently that could be causing interference with the cameras?
Most of the cameras are at full signal strength. One is usually at 1 or 2 bars of strength.
I have the below cameras.
Arlo (first series)
2 x Arlo pro 2 (1 of these is connected to a solar panel)
Arlo Essential (connected to a solar panel)
Arlo Essential XL
Arlo Doorbell camera
Within the last 4 months I changed out my base to the 4540. I had no issues for the first few months, with no changes I saw that battery life dropped drastically. Now they do not last 2 days and they are scheduled to only activate between 4:30pm and 7:15am (even the cameras with solar panels don't last more than 2 day's).
In trying to trouble shoot the issue I replaced rechargeable batteries in one o the Arlo pro 2's and saw the same issue. I also brought all 5 cameras inside (minus the door bell of course) and charged them to max capacity. I pointed them at a blank wall within 3 feet of the base and monitored the battery usage. While in the room I could hear the cameras clicking as if they were activating multiple times for hours. periodically I would check the app to see if anything was triggered or recorded and found that nothing was being recoded. I sound like all of the cameras are getting a signal that is triggering the cameras draining the batteries. within half of a day with the batteries fully changed and no recordings the batteries are all showing approximately 63%. The only other thing I noticed is the base stations blue light changes to orange at different times. I wasn't able to correlate this to anything.
