13h is pretty bad still. You should be able to improve that. I get about 48h juice with normal modest use. Always 3g or wifi on. No streaming video though. The single most important thing is to overclock and undervolt. Also don't let widgets update too often.

I have configured mine to go into flight mode and use 250mhz max during night. During that time it takes ~50mAh.

hey can you please explain how you can configure your phone to be at night in flight mode?and for the 250 mhz maximum i have too overclock???

Battery life is only dependent on the individual's usage.

There are so many threads already existing with this discussion, you can see a summarized version of the same in many places like this.

I am not sure if you have to overclock för 250mhz. I have not checked it up. You need a program that uses terminal to execute though. Maybe CpuFreqUI will allow you to do this without overclocking. But i am fairly certain that you need the custom kernel for this.

I have configured Alarmed (install with app manager) to switch this for me. The flight mode is a preconfigured setting in alarmed.. so you would only need to select it.. and then choose daily.. and what time it should go into flight mode.

AlMehdi | # 16 | 2010-08-11, 23:44 | Report

Not entirely true. I don't do most of that stuff.. and still get 48h of usage. But sure if you play n64 games and watch a lot of youtube videos then the battery will not last long.

I still charge my phone when i get home from work though.. it is normally at 60-70% left by then.

Also.. if you don't need the browser. Close it.. cause it will take battery in idle.

thank you very much i try alarmed first.
but i dont want to overclock because of the warranty lost,
but i will install a system log app and look whats going on at night.
can you tell me a good syslog app??

AlMehdi | # 18 | 2010-08-11, 23:47 | Report

Actually.. you have syslog if you want it. Just go into terminal and:

1. sudo gainroot
2. apt-get install sysklogd

I use it my self. Another program that could be helpful is PowerTop.. though it can be hard to understand. You have threads about it here on maemo.org.. so search and you will find

If you have leafpad (my preferred editor) installed you only need to.

1. leafpad /var/log/syslog

You will need to restart too. Syslog will be bad for your battery.. but i value it enough to have it installed anyway. There isn't any other good log for n900.. sometimes "dmesg" is enough but it doesn't show everything and clears after every restart.
