i edit the file /etc/pmconfig and set the two vars to 1. tested with low and high cpu usage it's still solid. will report if any reboot occurs. guys just use vi to edit it. and do it as root. then just reboot it.

anyone with the right know how to get the n900 to charge via wifi? is it possible?

definitely not

I just bought a new battery from amazon (Nokia branded BL-5J) and I charged it yesterday with the phone off. I turned on the phone when the light turned green at it was at 96% which is normal from what I've experienced from this phone. I used the phone a little and the battery dropped to 90% and it was holding stead for hours, seemed to be a really good battery.

Later on I installed a few apps....Accelemymote GUI, liqflow, and IPTraf Network Monitor and ever since then the wifi has been coming on and the processor was at 100% and the battery was draining VERY fast. In two hours it went from 85% to 40% with no applications open. I've removed the three apps and rebooted. I have autodisconnect installed and no apps open. And the problem continues to occur. What could possible be going on in the background that is draining the battery so much?

I have no widgets running and I'm processor seemed to be pinned at 100%, however I didn't check the processes at that time.

A few hours have passed now (with me staring/watching my N900 relentlessly) and it seems to have improved. Can anyone recommend a good battery charger. I'm going to carry around two from now on.

@gardzan: Check your WiFi access point - does it support Power Save Mode?

Dear all!
During the last weeks my n900 battery seem to be broken. If the battery level is below 50% and I make a phone call it can happen that the phone suddenly tells me that the battery is empty and shuts down. My phone is now 7 months old and I made sure to properly charge it always (recharge only when phone tells me, etc.). I always have internet, bluetooth turned off. I don't have email checking or any other manual installed tasks that run in the background.

Here is a recording of battery eye from the last days:

Why does it sometimes tell me the battery is empty if it was at 50% and I started the call just 1-2 minutes before.

About one week ago it happed that I had 70% battery level and after picking up a phone call I had the message battery empty -> shutdown.

Also every 1-2 days the phone drops connection and asks me to enter my pin code again.

Do I need a new battery or is the phone broken?

simply uninstalling catorise and the cpumem applet sent my cpu usage down dramatically on hildon desktop thus giving me leaps and bounds greater battery life. try it for one day you will notice the difference, I dont find myself running for a charger every 2 hours.

I've bought a new battery and I'm using the network switch applet to set to 2G whenever I don't need Internet access.
Now I have 2-3 days standby with no internet usage and just a few phone calls.
The sudden power drops are gone too.

Lucky the batteries don't cost much and they are user replaceable.

I'm using mobile phone for at least 15 years and I had no other phone or other technical device where the battery was wrecked after 6 month.

Maybe just bad luck.

I just edited the /etc/pmconfig and rebooted but my phone is still getting a horrible battery life of 6-8 hours, no noticeable battery life change whatsoever with smartreflex enabled or disabled... although it is noticeably hotter with smartreflex enabled...

I have 2 spare batteries with me all the time. 3 batteries a goes only half day for me.. I have seen battery drain in less then an hour. I will buy a new mobile phone and use N900 at home connected to charger all the time.. I really like this device but because of ridicilous battery life it is unreliable for daily life and business.. but at home connected to a charger all the time it is a good internet tablet.
