The previous algorithm woke up every 10 seconds and re-computed everything.

So is the increased battery drain from SCBS just moving from 10 second polling to 5 second or is there more to it?

Is there plans of merging the kernel and changes to the autobuild source repository. It would be great to have scbs support with the latest kernel.

Fyi, the init.android binary creates the msm_camera nodes based on uevent messages from the kernel. Any mknod commands you put in the /init script are obliterated anyway because init.android creates /dev from scratch.

Re: [TESTING] SCBS: Improved battery meter system

jonpry: your app is reading Battery Voltage and reporting it as capacity. This fixes it.

Code:

diff --git a/app/src/com/prymfg/babs/HtcBattery.java b/app/src/com/prymfg/babs/HtcBattery.java

index 3a7830f..e6c4acb 100644

--- a/app/src/com/prymfg/babs/HtcBattery.java

+++ b/app/src/com/prymfg/babs/HtcBattery.java

@@ -73,7 +73,7 @@ public class HtcBattery {

         if(real_device)

         {

             try {

-                String str = readFileAsString("/sys/devices/platform/htc_battery/power_supply/

battery/batt_vol");

+                String str = readFileAsString("/sys/devices/platform/htc_battery/power_supply/

battery/capacity");

                 return str.substring(0,str.length()-1) + "%";

             } catch (IOException e) {

                 return "busted";

(I've also fixed this in your kernel code so that it doesn't highjack the batt_vol reading with capacity any more, since it's already reporting capacity in the capacity node where it belonged... http://lists.xdandroid.com/pipermail...ay/000272.html)

Re: [TESTING] SCBS: Improved battery meter system

Is this needed in FRX071?

I don't know what you mean by "needed".

If you mean "included", then no unfortunately it is not. It's immensely helpful, but unfortunately the code never made it mainline.

Re: [TESTING] SCBS: Improved battery meter system

ok, thanks. Yes, that's what I meant

Re: [TESTING] SCBS: Improved battery meter system

are the files in links above compatible with the later build FRX071? Will replacing the zImage and rootfs provided with 7.1 affect stability or features of the system?

Probably. Run at your own risk... Unfortunately this stuff is pretty outdated, so you'd be taking a step forward with battery and a step back with everything else.
