Underclocking/undervolting when idle for battery savings

    Lately I've seen a few posts mentioning that underclocking and/or undervolting when idle, using a CPU control app that is made to do so, helps with battery life. I installed AnTutu Battery Saver based on the logic that Dracable trusted AnTutu CPU Master enough to put it in DrAndroid Lite, and I trust him.

    It seems to work the way it should.

    I think the end result is that my Venture, already horrifically unresponsive and slow to come out of idle (answering a phone call is a stressful experience!), seems to be worse. Has anyone done something similar with a Venture and had better success?

    Ive only used antutu's cpu master, and their benchmark app. Honestly, as far as cpu managers go, i prefer SetCPU. I only added antutu cuz its a free app. As far as battery management apps go, i discourage them altogether. Its just 1 more service in memory, sucking down cpu usage, and therefore draining battery. All of the options battery saver apps give u r usually able to be done manually. They are just "convienience" apps, therefore making it a waste of ram/cpu. I got decent battery life on the Venture if i kept sync off, kept brightness all the way down, kept wifi/bluetooth disabled and gps turned off. i used to surf the web on it constantly too. U want even more battery life? Throw your phone in airplane mode when not using it.
    As far as underclocking/volting go, underclocking a tad may help a little bit. As far as undervolting goes, i think, if i remember correctly, the kernel has to have support for under/overvolting, and i dont think that was added to the drandroid kernel.
    Keep in mind, that WAS my first try at an OC kernel. Im sure there are probably a few things i didnt get right! U could always try to reflash the stock kernel and see if it improves anything. Either way, keep us informed! Anymore questions, feel free to ask! :)

    Airplane mode isn't an option for me...my phone's first and foremost job is to receive phone calls and text messages whenever they may happen. I use the stock power widget with wifi, bluetooth, GPS, data refresh, and brightness. I keep them all off except as needed. I also added a widget to turn off mobile data; I rarely turn it on, and almost always am plugged in with a car charger when I do. I live, drive, and work way out in the sticks and I think my phone uses a lot of battery just struggling to keep a signal.

    Definitely struggling to keep a signal is a battery drain. Keep in mind tho, that widgets r another huge drain of battery, and again, just another "convienience". Best to have as little widgets as possible.

    If he is running a venture, he is on virgin mobile. these phones are available on the u.s. Cellular network too, but it was rebranded as the alcatel one touch premere/ot909b. The venture is exclusive to virgin mobile tho :)

    Yup, Virgin Mobile.

    I used to have zero widgets, but now I have the stock power widget, the data widget, and a small timer widget that I believe is well-behaved. The widgets have not reduced my battery time (and the power/data widgets have immensely helped by making it convenient for me to turn everything off and only on when necessary).

    I understand that, but what i was trying to say is that turning that stuff off/on manually without having the widget active should give u a little better battery than using the widget to do it all. The battery life is soooo bad on the venture, u really gotta try hard to squeeze every bit of life out of it that u can. LoL! Personally, i always carried around an xtra charged battery with me at all times, just in case. Im loving not having to do that anymore with my new phone. :) i get to leave on sync now, have all the widgets i want, etc... And i dont gotta worry. The charge lasts me all day even under heavy usage :)

    I'm not sure about those widgets. Like I say, I don't think they cost me any power, and even if they do I think it's less than the power needed to keep the screen alive while I dig around in the settings menu...that mobile data toggle is like 3 or 4 menus deep.

    I carry an extra battery too, but I try to avoid using it.
