    Hi guys,

    I was hoping someone could help with a weird issue I've been having. I switched to SS 5.4 (thank you Chevy, AWESOME work) and started playing a bit with kernels to see which one gave me the best battery.

    When using Chevy's kernels (I've tried 800 ULV and LV, 1000 ULV and LV), the phone runs OK and with regular useage I get around 15 hours of uptime. When using Deprimed's without any customization (just running the overclock and primed scripts) I get around 20 hours uptime with regular use of my phone.

    Now, here's where it gets tricky. With Chevy's kernels the Android OS process is just normal, but with Deprimed's the Android OS usually takes around 25% of battery useage. But as you see above, Deprimed's kernel gives me better battery life! Weird, huh?

    Any ideas as to what might be going 'wrong' with Deprimed? I mean, if I can get Android OS to a lower value, in theory, the kernel should allow me to have even better battery life, right?

    That is strange, my understanding is the more Android OS usage means the phone isn't sleeping properly and that can be caused by too low of a voltage on the kernel.

    You can install spare parts off the market to get a better look at what's using the battery when the phone should be sleeping.

    Open the app > Battery usage > change the top selection to 'Partial wake usage'.

    Ya spook i was having same problem when using deprimed kernel though i didn't test it enough to see if i got better battery or not.

    My OS typically is 2-7% but with deprimed it was about 16%. maybe ill battery test deprimed a bit tomorrow.

    Spare parts still says that partial wake use is Android OS on the top... followed, strangely, by Facebook (weird 'cuse I seldom use it, I'm a FriendCaster user)

    Try running it without the overclock script, all that really does is drop the voltages down from the "stock" settings deprimed comes with. If you find it works better you can redo "primed" and start tweaking the voltages up on the 20overclock script til you find a good balance.

    Try clearing cache and delvik cache and lemme know if it helps. I can get ULV 800 chevy's kernel to start fine but after a while android OS shoots up and i think when i clear cache/delvik cache it helps the problem for a little while. Still testing it.

    Maybe it has to do with the logging being enabled on Prime's kernel compared to disabled on Chevy's?

    Well, I cleared cache and dalvik and what do you know? Android OS did go a liiiiittle bit lower, but now I have Android System shooting up. Battery life seems unaffected.

    Next test would be to try Deprimed at stock levels, see how that works out.

    using deprimed, i got 10% android OS and like 50% running according to spare parts yet after about 18 hours(mostly idle/standby) i'm still at 70%.

    Weird, huh? At least I got the Android OS process to go down a bit (albeit battery life seems improved only so slightly). The culprit? Bumblebee. When I switched from Bumblebee governor to Ondemand, Android OS went from over 20% to 13-16%.

    Chevy's still faster but eats my battery quicker :(

    I love chevy's kernels but being able to set my own vsels/freqs with deprimed just makes me feel like i have even more control and i like it :).

    Same for me. I'm getting amazing battery life with the Deprimed Kernel. I just don't ask question and thank jeebus

    Jeebus! hehehe So, if BFS is causing it, could anyone explain why AndroidOS is so high and battery life so good?! o_O it just boggles me hehehe (just to think that, if 'legend' is true, getting AndroidOS down in this kernel would get even better battery life...)

    Ya i swtiched to one of the other kernels without BFS and android OS is down but battery life is worse.

    So, I guess BFS is the culprit for great battery life but increased AndroidOS... buuut, I also managed to gain about an hour of extra battery life.

    How? Deleting an app I don't use: Facebook (I'm using FriendCaster). For some reason, even though all notifications were off in the app and even logging out of my account, the Facebook app always took 5-8% of the battery cake. Weird thing? It only happened on Deprimed (I monitored it in Chevy's and Facebook app never appeared).

    Won't miss the app, though...
