PS. No matter you are connected to a wifi network or not, the wifi usage just kept going up.

How much data do you see during a period of time (30s, 5min)? KiB? MiB? If you see KiBs, it is probably because the Wi-Fi interface is communicating with the network event when it is not connected to. This is dependent on the near networks.

Hi, salva,

I saw around 100KiB in 10sec~30sec.

However, the serious thing is that the Wi-Fi was not enabled that time.

If the interface is on then that amount of transfer is normal but as you say Wi-Fi is off, let's ensure Wi-Fi is off indeed:

STR:

With the device connected to a PC:

0 - Flash the phone
1 - Open settings and ensure Wi-Fi is switched off indeed
2 - If disabled, open and adb shell session
3 - Emit the 'netcfg' command

Expected:
If the interface is off -> no 'wlan0' entry should appear at all. If it appear, it should look:

wlan0    DOWN

If the interface is on -> an entry with the following text should be shown:

wlan0    UP

Hi,

Sorry, I was busy at other things and forget to close this one.
You are right! The wifi in settings app showing that it's offline but it's not.

Close this as invalid bug and open another bug for tracking the above mentioned issue.
