I have just been reading about battery drain problems and have got to say this is the best app for reducing battery consumption.

I have it set to psm between 2200 and 0800 with all connections closed but not on flight mode. I have it set to 2g when idle and 2g when on wlan as 3g in my area is poor signal quality. So I only use 3g when away from home and office, so mainly travelling where I would be using very little data anyway.

I have gone from a day on one charge to nearly 2 days with the same usage.

Superb app!
