my experience:

charged with unit on android standby(not using it), limited to 80/80 at night(ard 12am), once the charge is full, plugged the usb off, and turned the unit off.

in the next morning at ard 10, turned on the unit, the batt shows 75/73. so the batt discharged while the unit was off.

never happened on android 9 firmwares, luckily can roll back to previous firmware. i will wait until android 11 firmware is fixed to install it again later.

Honestly surprised to see the battery drain you guys are experiencing, hope it gets fixed soon. My dx300 has been off since I did the update on the day of release. I tried a song or two on the stock player and on Neutron at the time. I just turned it on and these are the power values I still have. Not an issue on my unit it seems. Haven't even done a full reset yet either.

I left mine on standby at 19% digital over the night, by morning it shut down. Even the analog battery drained a lot, which never happened before.
This has never happened on Android 9 as well, so there is definitely something wrong with the new firmware.
I am currently charging it but disabled the battery saver option. Maybe a full charge will recalibrate it, let's see.

Battery consumption appears to be caused by amp use, not Wi-Fi/Bluetooth or apps
I am using AMP11.1

Battery at 100%.
Wi-Fi/Bluetooth: Off
4.4mm headphones connected
MangoPlayer plays for 5 seconds and stops
Checked after 15 minutes in standby mode and it was A98% / D97%

Recharge after reboot
Wi-Fi/Bluetooth: On
Connect 4.4mm headphones
Connected to FIIO BTR5 via Bluetooth
Use MangoPlayer and stop after 30 seconds of playback on BTR5
Checked after 15 minutes in standby mode: A100% / D99%.
After that, when I played the song on BTR5 for 60 minutes, it was A100% / D96%.

Is it possible that the firmware has the wrong amp controller and continues to control the power supply unnecessarily?

Has anyone collected (at least mentally) a list of the changes that have been made with the new FW, since there is no official changelog (that I have seen)?

Just in case the black-screen/non-responsive buttons happen to anyone else, what fixed it for me was waiting for the battery to die and having it power off. Once it was off and showing the red battery icon on screen I charged it for a few min and powered on right to Android.

You will have to use the .img firmware and the 660 Tool. I think the Tool is on the DX320 1st page and it is the same tool you use on a PC for the 300, 320 or the DX240. Then with the 660 Tool, you have to use the .img firmware.

How are you trying to install back to 1.07? Normally you could just use the image file (on the root of the internal drive or a micro SD card inserted; also in the root of the card) and go to "Update Firmware" in the options menu, and point it towards whatever FW you want to install. But since the new FW changes the version of android altogether you will need to download the FW 1.07 to your pc, then download and use the 600 Tool from your PC to reload the DX with the FW you want. From there, you can do the easy method to go to any other FW on android 9 (which is all but the latest one). The 660 tool has instructions for use.

660 Tool

If that doesn't work, just search the forums for the DX320 thread. It is the first post on the first page.. G'luck to you.

Haven't even done a full reset yet either.

I never did a full reset either, and I'm not experiencing any battery drain.

How many did a full reset and are experiencing the problem?
