What values you use for undervolt? Do you ever get a reboot due to undervolting? I'm going to do some system tweaks to help with battery usage. Btw battery manager has battery profiles you can use for night and day. Do you use smart actions or tasker is better?

For undervolt I use:
#!/system/bin/sh
su
insmod /system/lib/modules/symsearch.ko
insmod /system/lib/modules/overclock.ko
echo 5 1200000000 52 > /proc/overclock/mpu_opps
echo 4 1000000000 51 > /proc/overclock/mpu_opps
echo 3 800000000 50 > /proc/overclock/mpu_opps
echo 2 600000000 40 > /proc/overclock/mpu_opps
echo 1 300000000 26 > /proc/overclock/mpu_opps
echo 307000000 > /proc/overclock/gpu_opps
On my previous razr maxx I had to use 26 41 51 52 53, anything lower cause a reboot but i've been luckier with this phone and was able to use the lower values. I have noticed that on both phones, changing the lowest voltage of 26 to anything lower caused problems, even if I tried just a 25.
My battery life is probably due to the great signal I get in my area (grand rapids, michigan), and great 4g that I have.
I did try Smart actions, but the amount of profiles that I'd have to use in order to check my data every half hour would be too much editing for me. Juice Defender does it fine for me, and puts me into airplane mode at night which i'm sure helps immensely with battery.
I have Tasker, and have toyed with it. I've used it to do what Juice Defender does, but in the end tasker is just something I tinker with. I did have a profile with tasker that did allow me to shake my phone to make it full brightness, but I find I like lux better for brightness control. I do use tasker to change my sound volumes based on my location when I get to work, and to turn off my gps all day except for when I travel to work, and when I travel home.
I haven't really played with battery profiles, but I'll give it a shot. I do notice that I always get a nice savings in battery when I use setcpu to do the mix-max screen off profile. Of course this is all in my experience, and I'm sure others might not get the same mileage from their phone as I do.
