Guys, i'm new in this forum and i wanna share my experience with my n900 (i got it 1 week ago). Like all of you, i had problems with the poor battery life in the n900, tried many settings to improve the battery life 'cause only worked for me around 8-10 hours. Yesterday i turn it off the GPS and with no widgets like facebook or forecast, put brightness lvl 2, disable light notification (only for missed calls and sms) and now my battery is around 80-90% in 18 hours!!!!!!!
Newbie here with the n900. Here is the two test that I've done with my phone with approximately the same type of usage over a day. I did both of these test twice and got the same outcome both times.
Test 1 - Fully charged the battery, from dead, in the phone and kept the wifi off and my cell service on 2g except when I needed it to be otherwise. The result was my battery would last around 4 to 5 hours.
Battery charge time was approximately 3 to 4 hours to full charge according to the phone.
Test 2 - Fully charged the batter, from dead, in an external charger then ran the same service as test 1. The result was my battery will last around 11 to 14 hours. The battery charge time was approximately 6 to 7 hours to full charge according to the external charger.
Mate I tried to edit this in midnight commander, when I go to save I get a "cannot save file" dialog box, even when I try to save as with a different name . . .
Any other method to edit and save this file ?
btw I am only editing the value of vdd1, as this is stable and the benefits of testing thus far has doubled my battery life !
to get smart reflex working download cpufreq app, it has a smart reflex option and is surely easier than editing files etc...
@satchl
What was the cpu usage like on the first test?
even if you anable smart reflex in QCPUFREQ ,i dint think its affecting any configurations.........after enabling it in Qcpufreq when i check /etc/pmconfig the values for vdd1 and vdd2 are still 0.
enabling it means vdd1 and vdd2 has to change to 1
I used to use it in cpufreq and perhaps it doesn't work 100% although I was sure it did, I no longer use it though it crashes my phone when overclocked.
ok super linux noob here, but i found out how to change and save pmconfig file.
using vim editor:
1. open xterminal
2. sudo gainroot
3. cd /etc
4. vi pmconfig
5. move to the "0" on the line "sr_vdd1_autocomp 0" and press r, and enter "1". Then repeat for "sr_vdd2_autocomp 0".
6. to save " :w "
7. to exit " :q!:
hopefully that works for you.
*** note: i just changed this, so i do not know if this will increase battery life.
Dear all.
i found a way to improve the life on the n900 battery, usual my n900 it take just 24 hours before it will be dead but now it take 2 days with 12 hours working on my device.
all you have to do is recharge your N900 from the USB cable from your PC and when the led turn to green remove it directly don't keep the led green to much time.
this way did work on my device and am sure that it will work on ur device too.
thnx in advance !
