Try to install and use some dbus sniffer application from extras-devel (sorry, I am on a run and don't remember names). It may give you the clue - what is a reason behind huge dbus activity.

I select 02 Mobile Web so I am always online and don't have to switch between mobile web and wireless.

By way of update I gave in and flashed my device last night. Before I flashed I would need a recharge by 9.30 to 10am after starting to use the device at 6am. By between 12 noon and 1pm it would be in need of its second charge. Right now it is almost 1pm and the battery level has only moved a single level. Looks like it should easily make it through the day without needing a charge. I can't even remember that ever happening.

The only problem is I have lost all the mods I made. I was hoping the backup app would restore all my mods but it did not. So now I have to go through the 90 page share your mods thread.,

Do you happen to be using a case with a magnetic closure?

No not using a case. Just screen protector. Does using such a case cause the device to have problems?

The magnets can trigger the "keyboard open" and/or "back panel open" sensors. The former will cause the screen to be on all the time while in the case (which soon zaps the power) as well as rogue screen presses, phone calls, etc. The latter can result in the media card being disabled/enabled & scanned repeatedly which would also affect battery life. It depends on the strength and positioning of the magnets though.

Hi,

I have the same problem with my N900, the battery lasts only about 2-4 hours when I'm not even using the phone.

The phone is also extremely slow when I try to use apps, open text/instant messages etc.

When I type "top" in Xterminal, i get this:



Any ideas what to do? If there are no other solutions, I'm probably going to reflash the device. The only problem is that I don't even know how to do that. Could someone give me clear instructions how to reflash the N900?

Thanks in advance!

my two pence: have you tried 'wifi-switcher'? my battery life was awful (approx 6-7 hours) before but i can get several days now. i haven't tried leaving the kernel modules loaded since updating to 1.1.1 yet but, to be honest, i'm happy with how it is now.

God damn... Your N900 rushes a lot... According to ''Top'', your CPU is running WAY TOO MUCH, and some daemons eat your battery.
I suggest you uninstall what you installed from Devel or Testing, and if it doesn't work, I strongly suggest flashing your device. I'd like to help in doing it, but I've got to go haha!
If you need informations about it, PM me.

I don't know if it helps but using Skype IM and the Modest email client for gmail have been the greatest battery drains for me. I need IM but I have since moved to web based Gmail and that seems to have a positive effect.

Hopefully, PR 1.2 will include some work on prolonging battery life.

Add to that some texting and 30 minutes of music.. and that should sum it all.

I observed it using the Battery Eye application today and saw that the battery continuously keeps dying even if I'm not using the phone actively.

I'm using the PR 1.1.1. The only reason I could think of is that I have tried out a lot of apps from testing and devel, but have uninstalled them now. I'm not sure if something hasn't been removed and is still eating the battery.

Can someone help please!!!
