Anyone with Dx300 + Android 11 running into battery issues after factory reset? I’m wondering if i should just go back to the previous android version. Just updated to android 11 on my dx300 and the battery life is horrible. Unit heats up and both analog and digital battery is draining without any usage.

After a reset, nothing changes. Both batteries are discharged when idle.

I can't go back to the previous firmware version 1.07.390 from 7.12.2022. The local update says that the update is not possible.

I have made the Factory reset, battery draining very fast . Will check if it will help. Ist there no problem to downgrade to the older Version?

Downgrading the firmware through the computer, most likely.

How to downgrade from PC?

On the first page of the dx320 topic there is 660 Tool with instructions. Next, download the firmware in .img format and flash it according to the instructions.

can someone give a link to the img file of the firmware image 1.07?

For people having problems with the batteries draining when "off" - is that happening also in the Mango OS mode? Or just in Android OS mode?

 

[JoelWilcox]

Yes, but I kinda had this problem already before android 11. The device would, sometimes, charge suspiciously fast, then the battery indicator would drop as fast, and restarting would show the correct %.
I suppose (and I hope) that is is a battery calibration issue.
Right now I'm emptying both batteries to 0% in order to calibrate the thing properly

Good idea. Results?

Installed back android 9 and the battery is not discharged. It's a pity that Android 11 is problematic. The sound on Android 11 was better.
