    Question Weird Issue: SS 5.4 + Deprimed Kernel

    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.
