You may want to call Sony and hear it directly from them as to what they say is draining your batteries.

I have Sony a6500 and a7rii.
Batteries are sometimes fine and sometimes not. I think it’s the batteries’ fault not the camera. I’m trying to determine which ones now. I have them numbered and will probably have to write
the numbers down in a journal to figure it out. Good luck!

My Sony A77 did the same thing. I traded it for a Canon 7Ti Rebel and have not experienced that problem since.

You didnt miss it, I don’t think that you ever read anything but the initial post.

Bingo! The simplest solution.

Or - maybe I simply replied to the post in itself because I agreed with the post.
You're right, you don't think.

Hi Steve
I read through other threads on the A77RII and the one thing that looked interesting was the memory card.
There was an entry where someone noted that a particular memory card was causing the issue (maybe brand?)
Even though I switch off my Nikon 7500 with the physical switch there is still power. When inserting the memory card a small light still comes on for a couple of seconds.

I would try the following.
1. Reset the camera to default settings, Remove the memory card, and Remove any items such as camera grip or flash, and see if the problem clears. If it does:
Add the removed items one at at time until the problem returns to determine the cause. if it doesn't return then the reset fixed it.

Quite some while ago I conducted a battery drain experiment on a Sony NP-FW50 and a Promaster NP-FW50. Airplane mode off. The Sony a6000 was "off" except when reading the battery % on the screen. I have since repeated the test with the Sony a6300 with Airplane mode "on," but have not analysed the data yet. Notice the 'stair-step' discharge with the Sony.

First of all, I am not suggesting that you go out and purchase a different brand camera. I mention the brand only because it was the equipment we had.

The last time my brother and I were backpacking together, we were using similar Nikon DSLRs with fully charged, similar age OEM batteries. I tend to turn my camera "off" between shots if it is going to be more than a few minutes. My brother left his on continuously for more than a week. Obviously, as brothers, we gave each other a hard time about this difference and kept an eye on battery levels. We both put the lens cap on when we were not actually using our cameras. By the time we got back to the car, the battery levels were similar for both cameras. I have no experience with Sony gear, but I doubt they would intentionally design a camera that could leave you stranded if you do not have the ability to recharge the battery daily. All other things being equal (unnecessary functions disabled, fully charged batteries in good condition, etc.) I would expect somewhat similar performance from other brands. As previously suggested, I would start by making sure that unnecessary functions are disabled. If the problem persists, there have been numerous suggestions made here relative to battery issues. If the problem still persists, I would be contacting a Sony service center to see if that (those) particular model(s) have any known issues or, possibly, need repair. Neither needing to take the battery out of the camera every evening (if it will discharge overnight, how much of its charge was used up during the day?) or needing to carry enough batteries to put in a fresh one each day would be acceptable options when I am miles from the nearest road.

Hope you find a solution that works for you without it costing you an arm and a leg.

The batteries are two years old and I have no idea how many times they have been charged. Unlike some, I take pictures not fill out spread sheets or date logs. I wouldn't even have a clue of how many shutter actions have been made and don't really care.

I will look into buying new batteries, all the overpriced Sony brand, but it will help answer whether the issue is new vs old, Sony vs. Wasabi, or a fault in the camera.
