[Android] Work around Wifi + Screen Off bug in HTC/Nexus One

[BinaryTB]

Apparently all HTC phones (includes the Nexus One and probably some non-HTC) put the phone wifi into a power saving mode which *drastically* reduces the power/speed of the connection, either causing timeouts or very very slow speeds.

I'm running stock Android 2.2.1 on my Nexus One and just confirmed that this bug exists by testing it with a ftp file transfer using swiftp, screen on & off, the transfer speed shoots up if the screen is on. This is with my wifi sleep policy set to "never turn off".

Here is the official Android issue for it:

Here is the Cyanogenmod issue for it:

And here is a fix (but looks like only for Android 2.3):

It looks like you can use "PARTIAL_WAKE_LOCK" on HTC devices to workaround this issue in older Android versions:
