Has anyone run into any battery issues with v0.4? I installed two days ago, and I've had to recharge my phone four or five times since then. Usually I can go a whole day of regular use on v0.3. I am using the latest ChevyNo1 800Mhz ULV kernel, and have setup up some setCPU profiles to curb the battery life somewhat. I am open to most suggestions.

I had a very similar setup as you and was experiencing the same issue. I tried several different kernels, but think I am getting closer. I am now using Chevy ULV 800. I also removed SetCPU and my task killer. I read somewhere that Chevy has all that built into his package, so it's actually causing the phone to work against itself.

Believe it or not, I am now on 20 hours and still at 70%. That's pretty good as far as I'm concerned. Also, it might help if you could post what apps you have installed. There are some apps that are known to love the battery...

I'm running P3's lv 250Mhz-1Ghz kernel and my battery life is great. I keep it on 1Ghz until my battery/temp reaches a certain level and SetCPU profiles kick in. I easily get a day of use, sometimes 2 days with medium use.

Medium use for me in 1 day = 100+texts, 10-15 emails, up to an hour of browsing and a few hours of streaming music.

It also helps that I'm always around WiFi though.

I've been getting pretty lame battery life with BBV0.4, however, it is a bit better with Chevy's 800mhz LV kernel. Still, it's not nearly as good as I got with BBV1.1 (Android 2.1) with Bekit's 1.1ghz LV kernel. Sighs.

How do you do a 100 text and maintain battery? Do u use autobrightness on the droid or manually set it?

I have EXCELLENT battery life with BB 0.4 but I'm running the kernel that came with it and have not changed anything. I'm also not running any theme. I would strongly suggest to anyone having battery issues to check the kernel they are running and themes they are running. I've done some tests on this and found out that most of the issues people have with their phone are linked back to the kernels they are running. Stick with 800 LV kernel and you should fine. If not then there's something else going on with your phone.

I use auto-brightness. I also do not leave GPS on and have my RSS, weather and other auto-updates on a nice refresh time.

Like I said before, I also am in WiFi areas a lot so that helps data wise.

I thought wifi drains battery more than 3g?

Cell radios use more power. When using WiFi for data you will get better battery life. This is at least what I've been told for years.

I am currently using the smoked glass theme for v0.4. I don't think that is the problem.

Do you turn off your 3g antenna? I assumed it was worse because the 3g stays on, so you are running two things instead of one.

3G stays on but for voice. The data comes in through WiFi.

Wi-Fi isn't optimized for mobile platforms; as such on things like phones, Wi-Fi actually uses more power than the cellular radio does.

Oh wow. Weird. I still get better battery life when using WiFi. Just using the cell radio I can basically watch the battery level drop very quickly.

"Wi-Fi is more energy-efficient than 3G when it comes to transferring data, so that is why 3G sucks up so much battery in that regard," he said in an e-mail to InternetNews.com. "Alternatively, when you look at how much energy the device consumes while idling, Wi-Fi is much more inefficient."
