Fast additional info, with yesterday reboot, kernel ideal loaded: 2 powertops (2 measures) at least

- wifi, internet, gtalk and skype disabled -> 400, 589 wakeups

- internet (3G) enabled -> 1068, 807, 52000 (I saw an update alert, ignored), 1004, 553, 463, 892, 719 wakeups

Let's see what I have in settings
+ connect automatically -> any connection -> 10 minutes (interval)
. Is this active even when the device is already connected?
+ exchange -> every 30 min during 8->16:00, perhaps too much, but one connection each 30 min is not so dramatic, isn't it? I change to every 4h.
+ GPS, enabled. Umm, I though it was disabled. Now I remember that I re-enabled it when I saw the the iphone didn't need to turn it off to have decent battery. However, I see the GPS working only when any map app is active, is it true? In any case, I disable it.

-> 567, 490, 482, 863, 497 wakeups

- gtalks and skype ONLINE -> 1461, 3398, 839, 603, 999, 796, 1353 wakeups

Notes: At the beginning, I disabled gtalk and skype, some days ago I started to just putting the IM in OFFLINE rather than disable the accounts. I understand that the effect is the same, but perhaps there are some differences (?)

Well, I don't know if these values agree with the poor battery time. I will re-flash the device and see what happens then. But I will install some apps because I need them for next days, so I'll be unable to do "clean" tests ...
