how's the M battery?

First of all I want to say I just got my Razr M a little less than a week ago , this is my first smartphone and so far I love it.
I tried setting up the location trigger and it didn't work well for me. I got the Powersaver app and that shut the wifi off but the location trigger didn't work well turning it back on; sometimes worked, sometimes not.
Another potential problem I see with this is that the location area is much larger than the signal area of the router. At work the building is large enough that I loose the signal in certain areas. The powersaver shuts down the wifi but the smart action will see that I am still at the location and turn it back on. Not a big deal I guess but it seems that they would just be constantly in conflict.
I may just use the powersaver to shut down then manually turn on when needed.
