I found out yesterday that my N1 min cpu scaling freq was only about 248mhz. On wake up from sleep, i felt a little sluggish behavior so i clocked minimum scaling freq to about 500mhz and i feel that my n1 is smoother now. And no battery loss!!

shahz : IMHO, the most power eater in N1 is the DISPLAY/SCREEN So, eventhough you set the min_freq to 500MHz, still nothing to compared to screen's power consumption, but you get more responsive.

i think do not use the live wallpaper better..

ccm: You are correct !! the Live Wallpaper is just eye candy... If you NOT open your home screen most of the time every 1 minute, then, the live wallpaper not using much power, I think.

Can i ask what kind of data plan are you guys using? And how much do you pay per month for that.

I am using Celcom 3G Voice + data plan. The data plan itself is MYR 98.

Shahz, do you mind share how you do that?

Exactly..Apparently, the CPU usage is not that hogging as much as the screen is.. I use auto-brightness anyway so it just knows when to use more when needed..My battery lasts one day approx which is good enough for heavy user like me

I'll share some cpu playing games with you guys. Please be careful when playing with these settings though. Use them at your own risk.

First of all, we are very happy to have cpufreq utility in our android phones which help us to tweak the processor to our liking..Here is what you can do..

1. Connect your phone to your computer (put your phone into sleep mode for about 10 seconds to let it idle)
2. After 10 seconds, run this command in your cmd/terminal



You will likely get a value of "24500"

This is the value your phone is currently running (in sleep mode) and will be the freq when it wakes up. Jumping from 24500 all the way to 1GHz is a long journey so you may see som sluggish behavior until the CPU ahieves its optimum frequency and stabilizes..Now, lets check the min freq set to see whether your CPU is really running at its min speed already..To do this, run this code:



This means, when your phone is running at its minimal usage, your CPU clocks at 245MHz..Now, we should check what are the available frequencies compiled with our Nexus One. For that, we run this line of code..



You will see a list of available frequencies which range between 24500 to 998400 (1GHz)..So, now we shall change our minimum frequency to 499200 (500MHz) so the phone will always operate at least at 500MHz (which is roughly the frequency the HTC Hero runs at). To do this, we run this line of code:



Now the min scaling freq is all set to 500MHz..You can verify it with the following line of code..



You should see "499200" as the value..

Beware: Do NOT set your CPU usage too high or you may overheat your phone resulting in crazy battery drainage and even worse, burn your phone
If you followed the little guide above, you should be just fine. I figured out this myself so don't blame anyone (even me) if anything goes wrong. Do it at your own risk.

P/S: If I'm not mistaken, you need ROOT to achieve this but I'm not sure whether the unlocked bootloader allows cpufreq tweaks..

Have Fun

i m using voice plan plus unlimited data plan (rm38 for the data plan)
normally i just need to browse map, receiving email..upload photo to my picasa or facebook..I think rm38 is enough already for me, but don't expect it to watch youtube in high quality..

if i am in wifi area, i will use the wifi for higher speed

planning to switch to RM98 per month (3.6mbps) but need to survey more how fast is it first...

then... 1 thing i would like to point out.. in my office here my phone always dead..always no network coverage but this never happened to my previous phone (n95, blackberry storm 9500)

Why the difference in price although both are unlimited? Speed?

speed...
128kbps,384kbps,3.6mbps..
rm38/68/98

If you are using adb shell commands, do enclose it with qoute ''. or " especially when handing redirection ">"

Example
$ adb shell 'echo 499200 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq'

kalu guna prepaid utk 3g data kat nexus 1 kejap je abih.....aku isi rm60 3-4 ari dh abih....lastly aku delete 3g setting hya guna wifi utk surfing tenet, sync FB & gmail........ kohkohkohkohkoh

Worked fine with me without the quotes in Mac's Terminal

kat sini ade limit 200mb utk 7.2mb, pastu die limit gprs je Tu yang kene tau berape banyak pakai.

N1 ETA = tomorrow

by HTC or communication company??

what do you mean?

N1 will be introduced in Malaysia tmr right?

erm no..i dont think so. All import only

Of course..or maybe google will send to us ;-)
