[X] I am reporting a bug in the Onion OS (Note that Onion devs can’t fix inherited issues with RA Cores)
[X] I have reviewed the Onion Wiki and did not find the answer
[X] I have searched the existing (open and closed) issues to ensure I do not log a duplicate

Onions OS Version

V4.2.0.2-beta-4c7e2db

Miyoo Firmware Version

202303262339

Provide a clear and concise description of the issue

While charging the device, miyoo mini plus, the battery percentage is not displaying correctly or calculated incorrectly. After couple hours of charging the battery percentage was still below 10% (started charging when my device showed 5%).of

Steps to Reproduce

Charge the device (miyoo mini plus in my case) when the battery is below 10%
Wait for couple of hours(my case) or few minutes
Remove the cable to check if the battery has more juice than the start of charging (the charge would/should be the same as the start or hasnt increased at all)

Provide any additional context or information that may help us investigate your issue

I removed the sd card with onion os on it(after 3-3.5 hours of charge) and used the sd card with the stock os and the battery percentage(or rather the indicator) showed the expected charge level.

I restarted the device with onion os (multiple times) to check if it would show the correct battery percentage, but it did not.

I'm also seeing this issue. However my battery percentage stays at 0%. Same Miyoo firmware version. I can see the batteries true percentage when I'm in the RetroArch app. Another issue is the OS boots me out of anything I'm in and returns me to the menu every 10- 20 seconds. I'm using a SanDisk 128GB Extreme microSDXC UHS-I Memory Card. When I put in the original micro sd card and have no issues.

Alternative steps to reproduce:

Start with battery below 100% on the Onion home screen
Tap the power button to sleep, leaving the device ON
Charge for a while
Unplug the device and wake the screen
Observe the battery level is the same as before
Start a game
Immedeately exit back to the Onion home screen
Observe the battery level is now updated to the correct value

Same issue with a SanDisk 64gb microSD. Any update on a fix?

Same problem. Also, the volume buttons do not work, and the application / game closes a few seconds after launch.

@mindougby sounds like you're using the wrong version of Onion

Aemiii91 commented 1 year ago

@ena740m same as above

I am having a very similar issue on version 202305052130. For me when I am charging, it says 0% battery, and when I unplug the charger it says it is charging.

Can confirm, yesterday I found my MMP fully discharged (although I left it 'fully charged' and switched off). I was able to switch it on while connected to the charger, launched a game, got a blinking red battery empty overlay a few times and the game would exit to menu after a while. When I disconnected the charger, the OnionOS battery level indicator claimed I was at 80-ish percent, which I clearly wasn't. Using Onion-v4.2.0-beta-dev-072c73c Model MY354 Version 202303262339

So no help on this or what?

Mook252 commented 1 year ago

Same issue here. Battery level permanently at 0% even when it's fully charged. Guess it's back to stock firmware then :/

Aemiii91 commented 1 year ago

@Mook252 and you installed the latest pre-release? (4.2.0-RC)

Mook252 commented 1 year ago

@Aemiii91 Thank you for your reply, I had thought I was on the latest version but I now see that I am not. Sorry for not checking properly. I will give the 4.2.0-RC a try.

Battery level permanently at 0% even when it's fully charged. I am using latest firmware 202306282128 and latest Onion V4.3.1 I also tried reverting to older firmware and to stock OS and nothing helps.

It's not the firmware, other firmwares have the same problem. Probably the battery controller is malfunctioning. If you remove the battery cable and plug it back in, the battery level shows correctly, you can try to solder a toggle switch that will disconnect the power to the device physically.

I tried it several times, I even disassembled it and examined board under magnification, nothing suspicious found 🤷🏻 When battery is charging red led is constantly on, then, when charged, it blinks, when it blinks I disconnected the battery and measured voltage with multimeter, it showed 4.11 V, then I played games until device turned off by itself, disconnected the battery again and measured voltage, it showed something around 3.3 V
