Is it possible the EL13 modem just sucks more battery than EK02 and EG30?
I used to go through only 10% battery over 8 hours at work with stock EG30 (rooted) and EG30 modem.
Since I moved to EL13, I go through 20 - 25% over the same period, with far fewer apps installed, otherwise the same location and usage pattern, and using various ROM's that claim they have kernels optimized for battery life.
Can the baseband really be responsible for such a vampire effect on the battery?

Hey guys, I have been getting great battery life on Calkulin's rom and did lose track of AOS utilization. However, when flashing the EG31 I had paid more attention to my battery life. My AOS usage has been single digits (3%) compared to 35-50% from before. And this is while the phone is in deep sleep or idle. I just wanna know if anyone is still getting AOS bug, especially w/ the new EG31 and Calks' rom.
i second this i love this rom. no more bug great. getting great battery life. spread the word
I never really paid attention to AOS before, never realized it was an issue. Every time I check it, its at 6% or less and that's on Calkulins 1.5a with with eg30. With this rom I have no problems getting home at 14 hours and still have more then 20% charge left. I see no reason to try other roms till CM comes out. There are certin tweaks in the the CM rooms that I miss.
Actually i found the answer. The new outlaw kernel by steady hawkin cuts down AOS. If u go to stock kernel, AOS will be back. There's a trade off between no LOS on stock vs low AOS on outlaw.

I am on Caulkins Rom 1.5a with the included Kernel and the EG31 modem. My AOS has never popped over 2%. Usually two and a half days on a full charge with moderate to heavy use. Completely awesome combo! Plus I dont seem to be suffering the dreaded LOS??

That's where I'm at
Haven't really tested what the implications of the AOS bug are in actual battery life in this situation as I still seem to be doing pretty good
Big can of worms here, but I'd like any first hand experience of various combos that have produced great battery life.
Seems to me like kernel has the biggest effect, followed by sometimes the rom and sometimes the modem(el 13 and 26 gave me some really bad battery life while talking).
Stock ek02 kernal was pretty good, i've tried desperado with probably the worst life, then el29 rogue stock with great battery life and now i'm on gunslinger, still testing but seems to be average battery with limited use.
I had ok reception with EL 13 and experienced some occasional high battery drain from phone calls. I tried el26 but had worse reception and el29 i don't notice much difference but it appears to be a good average all around.(data speeds vs. reception vs. battery vs. blue tooth).
Discuss
EL29 everything has been the best for me so far.
bump - I got my daughter this phone and she uses it a lot for music and that is a killer on her battery.
I'd like to root and pop on a ROM that is very battery friendly.
I've been reading on [ ROM ] Calkulin's E4GT v2.8.1 ... but I would really like to hear some experiences if possible.
Many thanks
Same as above....been running el29 modem with BLEND (latest) with the gunslinger kernel.....battery life is great

See my setup below... Provides over 24 hours of moderate use. Its a sweet setup.

I have been having poor battery life with blazer 4.0 When I leave my phone overnight the battery percentage drops 20-30%. I have been using blazer since 3.x and always had great battery life. My phone is about 4 months old. Anyone else having this problem?

No, great battery life here, be sure to wipe battery stats, and update to the latest kernel.

Which kernel are you using? I'm on EL29 right now
I've been having much worse battery life with 4.0 recently, I'm not sure what happened. I was having amazing battery life before. I've tried reflashing and calibrating nothing has gotten better. It could POSSIBLY be the FC/FB modems killing my battery, I used to use EL29.

Try bare rom converter? How many apps u have? Background running?

I'm running modem ek02 on my phone. I've tired the el modems and ek02 seems to work best on my phone. I haven't tried the fb modems yet. I have also tired reflashing and calibrating the battery.
Same here.I removed about 50 apk's including WiMax apk's(because im on Virgin Mobile) using 7zip before flashing this rom and my battery lasts only 12-14 hours with moderate use.
When i first got my Epic i flashed GB MIUI and i was amazed with battery life,it lasted more than 2 days,and sometimes the battery just would not die,lol.
I want to go back to MIUI so bad but all the devs jumped on ics(to early if you ask me) and GB MIUI doesn't get updates anymore and it doesn't have HW acceleration.But its almost perfect as daily driver.
I chose Blazer instead of Calcun's because it was more clean but im definitely not impressed with battery,i odexed it too.I haven't flashed any kernels or modems with it,can anyone recommend kernel/modem combo for Blazer 4.0?Maybe that will improve my battery life.
I noticed battery indicator is not accurate because my phone will shut down when battery reaches 3-4%,maybe its Starburst theme that i use on it idk.
I'll try to make this as simple as possible.
On VeNuM's GB ROM, I was getting at least a day on my battery, it was fantastic. Modem was EL29 (I believe, possibly 26 though). I could use the phone a lot and it still got good battery life. With the verizon PRL, forcing roaming 24/7, I could almost get two days on it since there was less time it was "Searching for service"
Now on ICS (have done stock, calk, venum), I have been getting dreadful battery life. Take it off the charger at 9 and by 3, after using the phone during my hour commute, it's dead. The place that I work has pretty bad service for sprint, barely hovers at 1 bar if I even have service at all. One thing I have also noticed is that even on stock (and stock PRL), my phone does not seem to roam, at all.
Here was day one on FE22 stock: https://www.dropbox.com/s/mwjr5j3nd5vgody/2012-06-06 15.36.08.png

You'll notice that there are a few bumps at the end. I did have it charging on the comp for a little bit before I left work, those are the two spikes. HOWEVER, it also rose on its own. It went down to 5% and then went UP to 6%, staying there for a bit and then going down.
There seems to be something funky going on, but I just dont know what. I'm currently testing what the difference is with the verizon PRL, I have that on there now.
Are there some battery logs I can post to perhaps decode this puzzle?
-----------------------------
Second question. How do I go about downgrading from ICS to GB?
Thanks a lot.
You should try calibrating your battery and wiping the battery stats at 100%. That would speed up the settling in.
I suggest using sfhubs Odin one click package to revert back to GB.

Something is keeping your phone awake. Download badass battery monitor and check whats using up your battery.!
I'll do that right now. I just took it off the charger an hour ago and it's down to 85, just sitting in my pocket. I'll let it charge back up to 100 and then clear battery stats. I'll use it today and if it's still bad, revert to GB.
You look at the pics? They're depressing.
i definitely think you have apps causing wakelocks. try disabling dropbox, facebook and other random programs that sync, same goes for other stuff u may have polling for updates. with exchange syncing every 15 minutes i think i get better battery life vs push. Kobridge tweaks helped a ton.
white signal bars- cm9, the other is stock fe22 w/kobridge
id defintely search the forums for better battery stats (the dev made it available for free to xda users) or badass battery monitor in the market (also free)
I'm on Kobridge aggressive! I tried moderate as well.
Can anyone else confirm the first reply as to how to downgrade to GB? A direct link would be nice as well.

Battery life is not as good on ics and I too had the same the same problem. System monitor wouldn't pick up any program eating up CPU. Took me for a few day to realize I had a bad install. I had to Odin back to el26 and re install. That seemed to fix my problems. Which is my understanding is the procedure one is supposed to take when flashing from ics. So regardless your flashing back GB everytime you flash roms. but might want to give ics another shot when you flash correctly.

Must say it took me several weeks to find the right combination of parts to get my battery right.
I found that several of the newer modems were overheating my phone and draining my battery in a couple hours. Right now I'm running wicked ff02 rom, agats ff02 kernel and fe21 modem. Battery never get above 90 degrees; and yesterday I got an 8 hour day of work with heavy use (no mid day charge).
Edit: I tried venums boa rom, with very good results too. He included badass battery monitor, which seems to be one of the best of the bunch.

I did downgrade back to GB, running Blazer's EL29 rom with verizon PRL right now and from what I saw it was decent, even through the first battery cycle with the ROM. I'll see how it runs this weekend.
If I want to go back to ICS, can I flash straight from EL29 or should I flash the EL26 kernel first and then upgrade?

ICS Battery life
I have been running "Wicked Sensations" now for 4 days, with the FF09 Modem. I also added the FF11 Kobridge Tweaks to the mix using the aggressive zip. I have been getting roughly 15 to 18 hours out of my battery. I keep my screen about 15% on the slider for brightness. I am heavy user and this seems to be the best combination for my SII. I came from Calkulin's 3.0 GB... If you decide to go back to ICS, this combination. Good luck.
Hey everyone,
I recently experienced some incredible battery drain while running Calkulins 2.7rom with the EL26 kernel + EK02 modem (without OTA EL29 update) which seemed to happen overnight. This prompted me to flash my rom+kernel to Calks ICS 2 v1.6 with the FE22 modem. However, this also resulted in rapid battery drain when the phone was trying to sleep. I used badass battery monitor and my "kernel" CPU % is at 99% when the phone is off. This results in a battery life around 7hours even if I do not use the phone once throughout the day. I have wiped again and tried a Venum ROM based on FE22 and I get the same results.
What is preventing this phone from sleeping? I haven't installed any apps.
