Good idea. Results?

Ok so far it seems to be all good. The battery levels aren't dropping so fast anymore.
At the very beginning the digital battery was charging super fast, from 0% to 30% in 20 minutes, but it slowed down around the 70% mark
The strange thing is that before android 11, the analog battery would charge first, then the digital one.
When both batteries reached 100%, I turned on the device and the analog was at 96%. Turned off, charged again. turned on again 98%. After at third time they were both a 100%.
In the end it took around 2h30 for a total charge, which is, I believe, the normal time it takes for a full charge.
I hope this will be enough to calibrate both batteries

I am confident these bugs will be addressed and the new firmware will eventually be safe. In the meantime, I am very curious about the perceived increase in sound quality with 11. Can anyone who noticed this please elaborate on how the sound changed? This would help me decided whether to upgrade at this point or not. Thank you.

this might help if you want to go back or downgrade firmware from android 11 to android 9 or dx300 v.107 so only 660 tool with img file will work for you not OTA file.

I have had my DX300 off and also put it in standby and I am not getting any appreciable drain. I don't understand why, since it seems so many are. I checked again to make sure I am on the latest FW and I am.

No battery drain problem on my DX300, after upgrading via OTA and performing a factory reset via recovery mode afterwards.

AMP12EXN on.

Edit : had my first battery drain on Jan. 18

In standby, which I never use but trying it all this morning, it looks like there will be about a 4% loss a day with the latest firmware. When the unit is off, I get no noticeable battery decrease. I was at 91% (digital and analog is 100%) and wondering why it would not charge when I put it on the charger, and then realized I had 1. turned it off at the % and 2. I changed the battery mode to charge to 80%. So everything is working correctly.

***edit: I checked again on standby and after around 7 hours the the digital battery has gone down to 90% from 91% and the analog battery is still at 100%. This is the current latest firmware.

Urrgghhh…. Updated to 11, all was fine, noticed the battery was draining faster than anticipated, powered off to prepare for a recovery boot to default it, and nothing.

Won’t boot any longer I plug into my PC and hear the usb connect sound but no devices show in adb or the qfil/qpst apps.

Tried plugging in with the forward button held. Unsure what steps to take next other than to leave it unplugged for a few days and see it resets once the battery drains.

I would do a 20 second or so push on the power button to get it to shut down and turn on or get it to shut down then hold the forward button and plug it into a charger and hold that until the screen turn on then use the volume control to go up and down and go to reset and push the power button to reset the DX300. You can also clear cache with this menu.

Nothing after holding in the power or any combo of buttons.

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.

Same here. Having way faster battery drain than on the previous android 9 version when idle so now i shut it down when not in use. (but that is kind of annoying)

Try leaving it plugged into a computer. The lower current from the computer can often wake up the system. Leave it for a few hours then try it again.

I am baffled why my DX300 has zero issues with the latest FW. It works fine on Android 11.

I also have the WiFi and Bt off.

Same here so far. 6hrs in standby. Analog dropped 0%, digital dropped 3%. Upgraded via OTA zip, and did not factory reset after.

 

[orcinus]

Let 10 hours pass in standby and 2% consumption
No abnormal consumption

Since i just got back to android 9, the sound i find on 11 before was fuller. The mids and mid bass were more present on 11. It feels louder a bit, or more powerful is the word..?

The older android 9 sound feels cleaner and wider though. Its very transparent.. and i realized i loved it too once i rolled back to 9.

All these are on amp12 btw.

Just curious, are you using google play store or apk pure on yr Dx300 ?
