    MWHAHAHAHAHAHAH

    Ok OK. Calm down I'll share...

    I'm using CM7 tickerguy B0.8
    And Mantera's overclocking kernel
    -Kyles Help Desk CAN HELP YOU DO THESE 2 THINGS
    (minus5252's Channel - YouTube)

    1. Brightness on the lowest setting
    2. Power Governor on Conservative in the Cyanogen MOD Performance Settings
    3. Min CPU= 460 MHZ ( I use this setting you might find varying success and can go lower if you want)
    4. Max CPU= 1900 MHZ ( I use this setting you might find varying success and can go lower if you want)
    5. Juice defender Ultimate = Aggressive
    6. Juice defender Ultimate 50% battery threshold
    7. Juice defender Ultimate Configure APPS

    • Set all apps that need 3G to enable (gmail, pandora, browsers, etc)
    • Set all games and apps that DON'T NEED or you don't want to have connectivity to disable
    • Set pandora to enable w/ off so radio stays on when screen is off
    8.Download Battery Calibration and follow the instructions

    TIPS:

    1. Delete all the extra non used widgets
    2. Move apps to sd card
    3. Go to airplane mode when you have no signal or your not using the phone
    4. CHARGE WITH THE CORRECT CHARGER YOU ****** (MOTOROLA)!!! My phone charges in about 1 hour!
    5. TURN SCREEN OFF WHEN YOUR NOT USING IT( Set it to go off automatically) based on preference
    6. Uninstall all the extra crappy apps your not using
    7. When your playing a game go into airplane
    8. Turn your wifi off or I recommend having JUICE DEFENDER ULTIMATE control it!
    9. SHARE YOUR RESULTS!!!!
    10. After making your settings mods download CPU SPY. Use this to monitor if your phone is going into deep sleep when not in use. (Contributed by Whyzor)

    Hmm. Why so high on the MIN CPU setting?
  3. Mobstergunz

    Mobstergunz Well-Known Member Developer

    the conservative governor tries to hang as low as you let it clock so with these setting it'll probably stay around the 800mhz to 900mhz area. setting a high min with conservative governor is a good idea because of this

    Exactly! Basically functions as on demand if it needs to go faster. But it never falls below 800 so it stays pretty swift when just doing simple tasks.

    Ah. I use Smartassv2, 122MIN 1024MAX on the CM7 Stock Kernel and it works beautifully. I get about the exact same results. AND! I don't need Juicedefender to do it. However, I like your way as well. Just not overclocked THAT high.
  6. justdoyour

    justdoyour Active Member

    BIG difference. Speed is everything when your multitasking!
  7. lifeblows10

    lifeblows10 Well-Known Member

    I guess it all depends on how heavy you are multitasking. I am glad to see you get such impressive results using such a high frequency... I think I will switch to a new kernel, just because I want to try to beat you. Hehehe ;)

    But seriously, kudos.

    Battery stat is most affected by apps that keep wakelocks, preventing the CPu going into deep sleep mode (usually when screen is off, use CPU Spy app to see). Normal idle during screen on, the CPU is at the min frequency, which I believe 800 is too high, When it's actually processing info, it ramps up to max frequency, how fast depends on the governor, conservative has slow ramp up time. Interactive/X/smartass/v2 has faster ramp up time, sacrificing little in battery.

    I've achieved 11 days on a charge with my OV using CM7 (turning off 3g, wifi, BT, GPS unless needed), also airplane mode during sleep. Now I've only had my MT for a couple of days (heavy use so far since I'm playing with it all the time, but I can probably easily stretch it to 3-4 days. I'll post more definite results in a week or so.

    Cool. I'll be waiting for that post.

    How do you underclock to 122min on CM7 stock kernel? mine does not give you any options for over or under clocking fixed at 245min AFAIK
  11. Prey521

    Prey521 Well-Known Member

    You can't on stock, you need another kernel like TheOC.

  13. lifeblows10

    False. You can use the Stock CM7 (or MIUI) kernel to clock to a min of 122. All you need is something like SetCPU or No Frills, and set it there. You can't do it from the CM settings, like you can with the other kernels (the ones that allow you to overclock.) If you want it to boot like that all the time you check the "set at boot" and every time you reboot the phone it will boot just like it.

    I would not advise using an additional clocking software outside of the one built into the kernel. As it may conflict with the clocking setting set through CM7 settings.

    HEY! JUST BECAUSE THIS ISN'T YOUR IDEA DOESN'T MEAN YOU SHOULD TRY TO BE HATTING ON MINE! (JK :) )

    (That was completely sarcastic. You do have a valid point.) However, I never have ran into a problem with CM7 and SetCPU or No Frills. And I've used it that way since day one. (Had the phone since Aug. 24. :) )

    Some preliminary observations. I can get less than 1%/hr drain on idle if the phone goes into deep sleep (as seen in CPU Spy app). I'm at 1d 8h since last charge, and have 47% left. I would've had more if some mysterious bug didn't appear where going into airplane mode prevented it from going into deep sleep last night (stayed at 245 Mhz) for 8 hrs, draining about 28%.

    Handy apps to improve battery usage are BetterBatteryStats, CPU Spy, & Current Widget (to get current readings, although seems to be only updated every 60 seconds).

    Cool. I'm currently at 1 day 5 hours 80%. I'll post a pic when I get to 10 percent for the final statistic with the the new tweaks I added.

    How do you get your phone to go into deep sleep and how can you tell if it's been going into deep sleep?

    Thanks
  19. Whyzor

    Whyzor Well-Known Member

    Download & run the CPU Spy app from market. Reset the counter, then turn off screen, wait 5-10 seconds. turn it on and refresh, you should see the deep sleep mode register (among other frequencies from the interactive part). If deep sleep doesn't appear, it takes some investigation into what apps you have installed and the settings in them that keeps them awake. Start with settings - applications - running services.

    This thread indirectly helped me out a lot. I found that the facebook app and business calendar pro app were both really keeping the phone awake. I have removed both and am relying on google calendar (built into phone) and the facebook page via browser instead now.

    I was hoping to find a fix for wifi in MIUI, but have so far been unsuccessful. It keeps the phone awake no matter what I do (awake meaning not in deep sleep, but clocked at 245 mhz instead).

    Have you tried telling Juice Defender Ultimate to control the wifi settings?
  22. Jmelz

    Jmelz Well-Known Member

    Not yet, I figured maybe something could be done at the rom level or some other specific fix. I've never used Juice Defender, only llama.

    I admittedly havent even tried llama again since the change from punkrom to miui, but I might give it a shot.

    Thank......I let it sit for a minute and it never entered deep sleep.....time to do some huntin!

    BTW, my batt life went from 100% to 98% in the few minutes that I unplugged it from the charger to run this test!!!

    Some related info from the CM7 thread:
    I have found that following those tips and using Juice Defender Ultimate to toggle my data I can get a full day of light to moderate use easily from a full charge (maybe more, but I charge it every night). Like it was stated there though, I only get a few hours with heavy usage.

    There is no way I am going to overclock to 1900. Maybe a slight overclock if I can see proof that it hasn't harmed anything and I get some sort of benefit from it. Since I don't play many graphically intense games, I haven't seen much use in overclocking my phone.

    I haven't tested it, but I have noticed with wifi and 3g off my battery life is immensely long, so I assume it is doing the "deep sleep" just fine.

    Here are the apps that I have always running. The one that I suspect may be keeping the phone from going into deep sleep is Lookout Mobile or Touchdown/Airwatch. All of the non system apps are must haves so I guess I'll never get into that Deep Sleep mode! :-(

    My Running Apps
    -Google Voice
    -Battery Defender
    -Touchdown
    -Sense Analog Small Clock
    -Facebook
    -Lookout Mobile
    -Go Launcher EX
    -Go Contacts EX
    -AirWatch Agent
    -SwiftKey X

    Running System Apps
    -DSP Manager
    -Google Services
    -Settings


    My battery has dropped 15% in the 40 minutes that I've had it off the charger. Only using it to uninstall a couple of apps and perform these tests. I'm running the latest OC kernel/Conservative Governer/122mz - 1.5ghz. I suspect that it's Lookout chewing up my battery due to the nature of the app.
