Learining client 2.1 wastes battery

[silfiriel]

Now I am satisfied with how my battery lasts (around 36 hours with the help of Juice Defender and Power Saver turned on)

however in power managment when I check what wastes the battery

something called Learning Client 2.1 wastes 25% of the battery, Waht is this and can I turne it off?

Phine is running on ICS

I updated to Jelly Bean too, and it seems the Learning Client is either fixed or gone. However the stamina mode seems to be broken now, since my Wi-Fi is running even when the screensaver is off - and turning stamina mode on/off seems to have no effect whatsoever.

So I can use GPS now, but my battery lasts less time  than before JB - before I had 3-5 days (with GPS turned off) now I have 2-3 days (irrespective of GPS) and the second biggest waster of battery is now Wi-Fi instead of Learning Client.

One problem fixed, new problem created, it seems to me.
