Good Info !
Haven't had any trouble since the firmware update, but good info on turning off those options in the infotainment center.
Thanks !

Seems like there is hope. We let the car sit for about 60 hours and the car then started with no issues. Battery voltage was at about 12.7.
The DCM firmware update seems to have helped !
Anybody else had any trouble since have the firmware updated ?

2020 Camry XLE purchased, Oct 2019 has had the battery drain issue 3 times. Dealership finally replaced the battery in December 2019 the third time I took it to them. 10 months after they replaced the battery Oct 2020, I go out to the car and experienced the same problem! Smart key System malfunctioning / Battery dead. I was livid, this was the 4th time this has happen. I called 1-800 Toyota spoke to a Case Manager and Supervisor while vehicle was being towed to the dealership. I was told by the Case Manager that they had just release an update to correct this issue. I told him to call my dealership and ensure that they had the update and would perform the procedure on my car. He did and once I got to the dealership they informed me they would replace the battery and complete the DCM Reset and Firmware Update EL1934 0.8 86741-#####. Toyota and the Dealership says this will fix the Battery drain issue. I am hoping this works. If you are experiencing the same problem, make sure that 1-800 Toyota documents your case and make sure your dealership is aware of the update.
They performed the same update on our Camry TRD today. Fingers crossed !! Dealer seemed pretty confident it will fix the problem. Thanks for the info !!

Same here. 2020 Camry TRD with 4800 miles.
First time the battery died was at around the 1500 mile mark. Car had been sitting for the weekend and on Monday it was dead.
Jump started and took it to the dealer. They found nothing wrong with it.
Happened again this weekend even though car had only been sitting for less than 48 hours. Unbelievable.
Good thing I bought a boost pack. Going to be needing it on a regular basis apparently.
Definitely wasn't the key fob as both fobs were in a different county than the car.
I've seen the TSB that essentially admits that the battery dies at about 48 hours. T-SB-0007-19
"A battery in a stored vehicle is subject to conditions that can reduce its performance and service life. These conditions include storage period, temperature, parasitic drain, and battery load. Because of these factors, battery inspection and maintenance are required in order to ensure proper operation and optimal battery life. As a matter of policy, Toyota does not provide battery warranty coverage for discharged and/or failed batteries due to lack of maintenance. It is the dealer’s responsibility to maintain the specified State-Of-Charge (SOC) of the vehicle’s battery while in stock and ensure proper SOC at delivery. To eliminate customer service concerns due to an undercharged battery during the first few weeks of ownership, ALL dealers should check battery SOC and recharge, if necessary, no more than 48 hours before to customer delivery. "
It's going back to the dealer again, but I'm pretty sure it's pointless to do so. Will see.
Have a funny feeling I'll be learning how to do parasitic draw testing very soon.
I see a lot of people post that they are having this issue but so far, no solutions. A quick read of the kbb website reviews
for these cars demonstrates pretty quick how big a problem this one is. Good job Toyota.

2020 Camry battery going dead

You can turn the fob off so that it won't communicate with the car. I can't remember the exact procedure but I think it's just push the lock button until the light blinks 4 times.
Pushing any button turns it back on. No need to put key in the next county or in a metal box lol.
I doubt that the smart key is your issue. Can't hurt to turn it off when not in use though.
