I went ahead and did this change a couple days ago, directly in my N900 as prescribed early in the thread (used Leafpad). Absolutely stunned at the change in phone's battery life! I keep the brightness usually at 60%, turn off the WiFi whenever I'm not using it, keep the GPS off, Bluetooth off, overclocked to 850Mhz using Ideal voltage... and this has had the greatest impact at increasing battery life thus far. On top of that, as others have pointed out, responsiveness of active apps (usually have up to 6 MicroB windows open) has improved.

I keep loving the optimizations that keep being posted! Not so much the fact that Nokia didn't seem to do any of this themselves, or that some things don't work quite like they should... but this community has been amazing at improving this device.

This is good news! can you check my steps below if im doing it right in xterm:

1. sudo gainroot
2. cp /home/user/MyDocs/custom_swappiness /etc/event.d/
3. root or sudo root?
4. chmod +x /etc/event.d/custom_swappiness

My battery life doesn't seem to be improving, should I just reflash emmc or?

Mr_Ryde | # 66 | 2010-09-07, 14:43 | Report

After reading this thread a few days ago I changed Swappiness to 15 and Page cluster to 1.

My setup:

Overclock 500-1000 on ULV. on V40 Kernel.
GSM only when not using internet or when accessing internet via wifi.
Battery Indexing Disabled using Tracker-cfg.
Battery is original that I have had since early march.

Standard use for me is some mild sms and calling. Some photos using fcamera, about 90 minutes of Angry Birds. Some internet browsing approx 1 hour (wifi) so far and the updating of weather and email over wifi once every few hours. Maybe an hour of listening to music.

It is now 46 hours after a full charge (reading in beecon snippet was 97%) AND I HAVE 35% REMAINING!!!

This is just outstanding. Plus there are the other benefits described such as snappy switching of desktops etc etc

@ Lilboymonkey - don't reflash your emmc. I have never done this and my phone works great. Have reflashed software twice. 1st to upgrade to PR1.2 and the other just to reload some apps after a huge clearout.

THIS IS KEY - if you have a bunch of dev apps and widgets then these changes will not really effect you much as those things eat battery

Ciao

what do you mean?
is it 77mb befor or after?

my ram-usage is always around 130-180 mb, even on idle. how did you achieve this?

lilboymonkey | # 68 | 2010-09-07, 14:49 | Report

So I should just reflash then?

Mr_Ryde | # 69 | 2010-09-07, 14:56 | Report

If you have recently uninstalled a sh&t load of apps from dev and fancy starting with a clean slate then yes I think it will be beneficial.

I actually tried to install Nitdroid but it didn't work out. I had good battery life beforehand, and then after attempting Nitdroid my battery life went to crap. Guess I'll reflash later on then when I get back home.
