1187106 - [Settings] Wi-fi is not fully disabled in sleep mode when "Wi-fi sleep" is turned on in Settings.

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Settings, defect)

Description

[Nicholas Nelson [:NicholasN]]

Attachment: adb_logcat_wifi

Description:
The user connects to a wi-fi hotspot and switches on "Wi-fi" sleep. Next, they lock the device or let the display time out. An ADB logcat is pulled, and the hotspot is disabled. In the logcat, it appears that the device continues to scan for a wi-fi connection, long after the device has gone to sleep.


Repro Steps:
1) Update an Aries to 20150723134401
2) On another device, create a wi-fi hotspot.
3) On the Aries, go to Settings > Wi-fi and connect to the hotspot.
4) Toggle Wi-fi Sleep.
5) Enable USB Storage in Settings.
6) In Settings > Developer, check Wi-Fi Output in ADB
7) Lock the Aries device.
8) Disable the hotspot on the second device.
9) Observe output of ADB logcat.


Actual:
Device continues to scan for wi-fi connection while in sleep mode.


Expected:
Wi-fi is fully disabled while device is in sleep if Wi-Fi Sleep is toggled.

Seems like this feature isn't working in 2.5 and 2.2 behavior is a lot worse with an OS restart.

NI component owner to take a look.

Also adding qawanted to verify the 2.2 behavior.

Tested this on another 2.2 device, and the restart issue didn't repro. However it did keep searching for a wi-fi connection. I also branch checked 2.1 and the issue does not reproduce there because wi-fi sleep is not an option.

Actual:
Device continues to scan for wi-fi connection while in sleep mode.

Is the USB cabled is plugged? Only when the screen is off and the usb cable is 
unplugged will the wifi be disabled after a while [1].

Thanks :)

I tested this by initiating download of a 1 gb file. I put the device to sleep at 26%, woke it 5 minutes later, and it was at 34%. I put it back to sleep and checked about fifteen minutes later, and the progress was at 88%. Based on these results, it seems like wi-fi is not turned off, and each time I woke the device it appeared that the wifi was not attempting to reconnect based on the status bar icon.

Tested with phone connected to wifi, wifi sleep enabled, initiated a 1GB file download, turned off the screen. The only variable here is whether or not the phone was plugged in.

- When phone was plugged in and I woke the screen 15 min later:
Download was still going at 8%.

- When phone was unplugged and I woke the screen 15 min later:
On lockscreen it says 'Download failed 5 min ago' and I visually saw the device reconnect to wifi upon waking screen. Which means wifi appears to have stopped at ~10 min after screen off.


I think it should be made clear to the users that Wifi Sleep will only take effect when the phone is unplugged. Currently the description of Wifi-Sleep in Settings > Wifi only says 'Enable to automatically turn off Wi-Fi during sleep to save battery power' - which does not mention anything about unplugging.
