[Q] battery life not improving with undervolt on Setiron reoriented kernel

[tehsam]

I have been using setiron's reoriented kernel for awhile now with the Voltage control app set at -75mV for 100, 200, & 400mhz and -50mV for all other frequencies. I am not having any stability issues and the voltages are sticking after reboot. However, I was expecting a pretty significant increase in battery life due to the undervolting and I have seen next to nothing. Battery life is not bad by any means but in real world use is pretty comparable to what I was getting at stock voltage.

people seem to be reporting really big increases in battery life, so I'm a little confused. have I not UV'd by enough? if that were the case I would expect to see at least some battery improvement.

I wiped battery stats/recalibrated the battery when I flashed. I do have BLN enabled, but my understanding is that this causes a really small amount of battery drain. any thoughts?

How much % of battery you loose after night|?

while idle with the screen off (background data enabled) I lose about 1-2% per hour. I lost 10% overnight most recently and I was asleep for 7 hours. that is about the same that I was getting at stock voltage.

all i can sya, is thst you losing not many %

If you are in a weaker signal area, then the cell phone radio is going to work just as hard no matter what the CPU voltage.

Battery drain can be a symptom of i9000 kernel and captivate modem.
Changing the modem and keeping 850mhz is a multi step process. I tried the kernel you are talking about but it's over rated.

if you want battery life flash a 2.1 rom and use unhelpful's kernel, 1.4.1 was the most stable on my phone but it doesn't have voodoo. 1.6 has voodoo and 1.7 has voodoo and clockwork recovery if I remember right. But I had random restarts, others did not report the same problems so who knows.

I would wait for captivate froyo source to drop. I'm getting decent life with cognition and no undervolting.

Edit after reading the whole thread your battery life seems normal, I don't see any problem, you can try more undervolt but test the phone completely. Make sure it doesn't freeze randomly, or on shutdown. Also test it with the charger plugged in, extra heat from the battery charging can affect stability.
