Help Wifi Sleep Policy Changes Back to 'Always'

[mug2k]

I've tried on many occasions to change the wifi policy (settings>wifi>advanced>keep wifi on during sleep) to 'never' but after a small amount of time It'll go back and it'll have changed to 'always' on its own. Is this a known bug and is there a way to fix this as I lose about 20% battery overnight atm.

Not sure of why that would be happening, but, i think, if you were to disable that, your battery would be even worse. Generally you'll get better battery on wifi vs mobile network.
