    whats weird with smartflex on, it seems as if it never has a scaling_min or whatever....

    It used to idle at 125, now mine is never there, same with 250... its constantly at 500.... i mean if it saves power... fantastic.... just doesn't make sense to me...

    Smartflex on with 500... we'll see...

    That's the point, you are not using CPU scaling, only the SmarFlex technology to regulate the voltages..

    I wonder if we'll see implementation of this by palm in future updates..

    If not, a reliable simple scaling app could make good money.

    I get this happening. Probably a bug in the Camera app more than anything else. Doesn't bug me, I don't spend that much time in it.

    Would be nice if we could see some empirical battery life and/or performance testing with variations of scaling and smartreflex at 500/550/600 MHz.

    I've been running for about a day now with SmartReflex set to 550MHz (600MHz crashed for me).

    Observations:
    * Battery life is extremely good. 10% drop in about 5 hours. After a 20min phone call, another 3% drop.
    * Performance is much better. Applications load faster and the gui is snappier with less stuttering.
    * Phone does not get as hot during YouTube videos. In stock mode, the phone would get noticeably warm when watching YouTube, which is to be expected. With SmartReflex, the phone runs much cooler when watching the same videos.
    * No crashes (at 550Mhz).
    * Camera operated normally, but I did not have it open for a very long time.
    * No flickering or artifacts when running different applications.

    For me, SmartReflex at 550Mhz seems to be a keeper. If you can get 600Mhz, more power to you. If you just want better battery life, SmartReflex + 500Mhz should do the trick.

    This would be nice to have. Are there any battery benchmarks that have been ported to this platform? I know that there are battery benchmarks out there that are intended to test smartphone battery life.

    Battery performance is very subjective and is subjected to a lot of noise. Not many of us will have the patience to sit down with our phones and run the same list of applications waiting for the battery to run down. A benchmarking tool would be very useful.

    How much stuff are you running in the background? (mainly email push, and sync, etc). With about 6 email accounts running (5 of which update every hour, one is EAS) I'll get about 3% drop per hour. So about 10% in 4 hours. I did do some SMS and web browsing though (light). Still, not bad at all.

    Weird enough, I switched to 550mhz, camera is fine. Then switched back to 600mhz, and camera is still fine.... weird.

    So has anyone confirmed that setting the cpu frequency above 500 is ok for the RAM?

    I can't seem to get SmartReflex to work... initially after rebooting after putting the script in the /etc/event.d directory, I ran the cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state command and got only 1 beside 600 with the majority next to 500... then after another reboot, it doesn't even have a 1, it remains at 0 next to 600

    When creating the script, do you just paste the code into a blank notepad screen and then save it without a file extension? ie. smartflex.

    edit:

    @wprater

    why would setting the CPU frequency at 500 be a problem for the RAM when the stock frequency is 500? do you mean 600?

    What do you get when you run the following?
    sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

    And:

    sudo cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

    If neither of those return 600000, then your script isn't setting the frequency. Doesn't matter what the extension is on the script, everything in /etc/event.d/ gets processed during boot time.

    I get 500000 for both... why isn't the script working? Is the script on the wiki correct? Do I have to change the permissions on the file with CHMOD or something?

    I had the same problem with copying and pasting the script. What I ended up doing was creating the file and typing it all in there. It stuck then.

    Here are things to check:
    Log in as root or have root priviledges
    Make sure the file system is writable
    Did the event.d script remain after reboot?

    All you need to do is create the file without an extension, just like you said. Should have worked for you from what you wrote.

    I only have two emails running in the background set to manual. One is POP and the other is IMAP. I also have my WiFi on and BT connected to my headset as well. Screen brightness is set to almost the lowest, which could be helping battery life.

    Pretty respectable, I may need to test this out...

    type this is in: cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

    If ur running on 600 than you will see numbers next to "600000"

    The autocomp registers are the ones that enable/disable SR.
    $ cat /sys/power/sr_vdd1_autocomp
    1
    $ cat /sys/power/sr_vdd2_autocomp
    1


    If you don't see 1, you don't have SmartReflex enabled.
