Hi

I recently bought a HTC Desire which I've become exceedingly fond of.

I've read (and been told by a colleague who owns a HTC Legend) that wifi should automatically turn off while the screen is off to conserve battery. I have the impression that I should be able to see the wifi icon turn on as I turn on the screen and unlock the phone. However, I haven't noticed that happening: The icon seems to just be on always.

I have then tried observing my router's DHCP table when the the screen is off, but I haven't observed the entry for my phone disappearing (and I don't really know how much time has to pass before the table not showing my phone.

Are there any settings that can cause this behaviour? What about programs? I current use smart monitor to log data usage as well as locale (using a SSID plugin and not the locale "location" condition). The only services I can see apart from those I think are OS services, are the ones for locale, smart monitor lite and the SSID plugin.

Thanks in advance

You could try pinging the phone IP address from a terminal window on your computer. Get the IP Address from your router's DHCP table, or from an app like IPDroid.

To ping

Mac/Linux/Etc:
ping 192.168.1.X

or

Windows:
ping -t 192.168.1.X

when wifi is active you should see responses, when it's inactive you should see timeouts. When you are done with ping exit with control-C

On old 1.5 you can control when it sleeps by doing...


Menu>Settings>Wireless Controls>Wifi Settings>Menu>Advanced>Wifi Sleep Policy

Change it to whatever you want!

Thanks a lot to you both

I didn't know that there was an advanced setting for wifi.... most other settings don't have that. I found that wifi sleep was set to "never". I'm now changing it to 15 min. However, as locale periodically activates wifi to check location, I might have to change the precision such that it only relies on cell towers.

is your problem solved by running through that setting? even i set mine to "after 15 mins", when i turned the screen on after like 30mins, i noticed that the wifi was till on...

Didn't see that setting there. Just wondering what does it do for "Never when plugged in" when it's not actually plugged in, turn it off after 15 minutes?
