if i remember correctly it was also discussed extensively elsewhere...but i can't remember in what topic..and i need to get up for work, so can't search again ;-)

Dan

p.s bear in mind that the linked topic was pre pr 1.2 so some of the bugs referred to no longer exist...as nokia has now cleared up all bugs and problems and has a fantastic ovi store...sigh!
Thanks for the link.

I think mthmob's view proves my theory.

100mW just use the battery much quicker !

I can't have access to the menu where you can change it, in settings->internet connections, I only have the option of
- connect automatically (any connection)
- search interval (10 minutes)
- X Switch to WLAN when available

To the right, a Connections and a Save button, and in the first, I see the connections available, I can edit them, just to change the name.

So where can I change the 100-10mw value???

* exactly what it can be seen here

* ok, finally
http://www.forums.internettablettalk...d.php?p=466904


Then, testing, however, I will see any change if I am connected to WIFI signal, I suppose, if I am connected to 3G network, my battery will be drained as fast as it does now??

After about 3 hour web browsing, by Wifi

Chances are you have a router where PSM is not properly implemented or enabled:

I didn't come to this forum from the start and even I have read about this fix three times already. The discussion always ends the same way: It doesn't make ANY difference if you use 10 or 100mW. The thread starter will find out this was just a coincident. You will NOT go from 17 hours to 48 hours of battery time thanks to this setting.

Actually, I really go from 7 hours to 48 hours of battery time because of the setting, I think.

And some people here have the same view.

It is easy to find that 100mW use more power than 10mW.

You said it was a bug, then is this bug fixed in PR1.2 ?
If not, then I think this setting still helps to save the battery.

Well, I know for a fact that when I set mine at 10mW at home, and when I go to my living room, I lose connection to my wifi router which is in my room.

But if I set it to 100mW, I can keep the connection alive and browse from the exact same spot. So it definitely does make a difference in terms of wifi coverage. So I can only guess it will also make a bit of difference in power usage if wifi is used heavily.

After installing update PR1.2 I found my battery lasted much longer then before. This was because it wasn't connecting in 3G mode and I had no wifi connection available.

Everyone should know and have the 2 Vital apps for the N900 which are the Wifi Switcher & the 3G Switcher. I had this before the update and to fix the 3G issue just installed the switcher again.

By keeping the wifi off when not needed and ONLY using 3G when needed for extra quick browsing (otherwise in 2G) you save a hell of a lot off your battery.

Btw a tip i picked from a thread here somewhere is by keeping the brightness level on 2. This also saves a lot from my experience. ( I sometimes use full for videos.)

Surely by using 10mW instead of a 100mW one can assume it would make a BIG difference. Im also going to try this now. Could be useful!

I dont know about the battery lasting for 48 hours. With casual use of the phone, a bit of wifi, music, phone calls, messages, actually even with phone calls only,thats quite impossible including the steps mentioned.
