Just read the Jakiman posts and ignore the rest of the stuff in this thread. His guide is the simplest/most accurate. Most of the other stuff I see here is shockingly inaccurate.

Care to elaborate on what is shocking an inaccurate here? OP has been given some good advice here. An explanation on why lowering voltage is better, empirical results on how to acheive the best battery life.

Please explain what is innacurrate here (obviously ignoring all additions by epitath) before you start throwing around baseless allegations.

Whut? Where did you get this from? You can have 250-950@<ANYVOLTAGEPROFILEYOUWANT> (assuming your phone can handle going so low)

From MY OWN experiance, for maximum battery I use 250-805@STARVING with SMARTREFLEX on.

• -Smart reflex is the CPU built in powersave mode, it is the best.
• -Starving voltage profile is a profile made by a user who was OBSESSED with running at the lowest voltage his n900 could take. (while yours may be able to hande even lower voltagaes or not at all).
• -250 as minimum because there is very little differance in voltage use between 250 and 125 but there is better performance with 250.
• -805 as max as it seems to be the highest SMARTREFLEX can take without freaking out.

but really if you want a nice simple overclock with very little risk to your system then just use:
then you can explore some of the more advanced features when you are ready.

Ignore EVERYTHING epitath and abill_uk ever say, they are the local trolls. I don't know why geneven has derided the advice given here, it is more or less sound info.

For further info, re-read jakimans guide. If you STILL cannot work out how to acheive what you are trying to do then ask SPECIFICALLY how to do it.

quick questions -
this thread got me playing with oc again yesterday.
I know its possible to check the cpu limits in xterm , but is it possible to check which profile you have running and if you can set smartreflex via the terminal?

also if smartreflex set via terminal results in reboot - would the reboot be in non smartflex mode?

thanks

when we save our voltage profile (to say my profile1), do we need to set it again every time we reboot? (in other words, does voltage not save to the changed kernel-config saved setting?)

also, if we use QCPUFreq to change profile, or "Load Preset", does it set it permenantly or does it go back to default after reboot?

how do we know what profile is currently loaded? does the output of 'kernel-config show' tell us somewhere?
