Okay, so Mediapad M3 isn't showing up under device names. Can I pick another Huawei device, or am I screwed?

I just picked the most recent Huawei device on the list at the time.

 

[MattP410]

I just picked the most recent Huawei device on the list at the time.

So that would be the only one that says (9 &10)? I'm assuming those numbers are Android OS's?

That is my understanding.

I also figured out Vanced. It wasn't automatically going to the option to install unknown apps, so I had to do it manually. Thanks again for all your help.

Battery Drain Issue?​

Hi.
After using the device for an hour, the battery dropped from 100% to 77%.
Just after one hour of use, it was 89%, but during sleep, it drops a lot.
I don't usually carry my tablet and I charge it immediately after use, so I didn't notice this issue until recently.

It's not rare for battery life to worsen after flashed a custom ROM, but I'd like to know your situation. Is this normal?

Yours sincerely.

Hi,surdu_petru
Connect to the WiFi Internet, if you turn off the screen to standby mode, the WiFi will not be automatically disconnected, but will remain connected, resulting in unnecessary power consumption.

I noticed a similar battery drain in my device. I left my tablet for a day on standby without charging and it went from 100% to 75%.

Sorry to muddy the waters, but I am not having a power drain problem on mine.

I never heard that the tablet is supposed to automatically disconnect when in standby??

Did you check if there were google update for example or if you have a kind of wifi automatic update?
Also can you check the apps in battery usage stats per app? Click on the 3 dots and click in detail usage

I have not this issue on my device, but as a workaround you can try to disable Wi-Fi & Bluetooth scanning !

 

[friedsonjm]

I wonder if there is a difference in battery usage between LTE and WiFi models? Mine is wifi only, and after three hours sitting it has not used even 1%

Due to the long experience on Huawei devices, (starting with Huawei Ascend P6) - this problem I have encountered frequently even on identical devices, but I suspect that it is different revisions of the same type of device where the hardware was slightly different - and most of users fixed thier issues by disabling WiFi/BT scanning !
