Hi All,
I recently flashed my phone to stock from Calk's 1.5a rom as I thought It was causing problems... I found out the tower had the issue. Anyway, I was getting unbelievable battery life with the following kernel, 2.6.35.7-SPH-D710.EG30-CL435734
Can anyone provide my a link so I can download it again. I'm currently running Calk's 1.5a Rom with the kernel it comes with and my battery life is horrible. At 2PM CST today, it was charge to 100% and I also calibrated the battery... I'm already at 79% and I've only talked on it for 10 min max, checked a few emails and that's it... Any help would be appreciated!
I'm currently on the following:
ROM - Calkulin's E4GT ROM v1.5a
Kernel - 2.6.35.14-rogue_ET-1.1.3+
Baseband - S710.10S.EG31
Its In the stock Tom, just pull it out

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?
I was wondering if anybody knew why my kernel is consuming so much energy at 80%, when Ive seen it consume on average 20%.
MY E4GT is rooted running the complete EL26 setup including the Blazer ROM, Thunderbolt script package, the recently released rogue EL26 kernel, and EL26 modem
please let me know if more information or details are needed
thanks in advance
What is the Thunderbolt script package? Sounds like some kind of wakelock going on. Do you have BetterBatteryStats to monitor usage more thoroughly?

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.

backup sms with "sms backup and restore"
backup apps with titanium or "appbak"
run the odin one click found here http://forum.xda-developers.com/showthread.php?t=1433101
if you dont want root, then run the autoroot package linked below(after doing above) and choose the option to remove root.

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.
