Assuming many of us got our EPICs on launch day or soon after.....curious if have you noticed any drop in battery life? Mine seems to be holding a charge as it did from the first few days of owning it.
This is the complete opposite to the Pre that I came from...I had to get a new battery after 7mos.
Am running SFR 1.2 with Twilight and SetCPU at Conservative 1000/200.
Same result
My battery is still being very nice to me as well.
I do have to say, running a custom ROM makes a world of difference. I have been running Bonsai, SR Frozen, and currently Simply AOSP, and get awesome battery life.
I went back to stock once to test a new ROM, and immediately remembered why I switched. After 5 hours of having my phone unplugged and just sitting in my pocket, I was down to 60% battery. Samsung should really catch on and throw some improvements into their stock ROM and then maybe it could actually be considered an improvement over vanilla Android.
My battery seems to be doing fine. Switched back to running RandpmROM hawk v4 from rooted.stock because I forgot how much the battery life on froyo sucked.

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.

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.
i just got my epic touch 4g but i noticed that when i had my photon battery would last all day on school but with my EPIC battery life only last till half a day, and even worse when i turned off my phone to 'conserve battery" my battery last even less
EX: i turn it off at 70%- and when i turn it on its at 54%
i am running FF18 ICS
is there another rom with stock touchwiz that have better battery life?
or is it possible that is my phone?
HELP!
I hear caulkins rom is good if you want TW. I use CM9 which isn't TW.
To let you know. Having a big battery drop after a reboot, is a known issue with ICS. One way to help is to put the phone in airplane mode, reboot and take it out of airplane mode.
Try Manufan721 rejected crack stock 1.3b Its stock with tweaks under the hood for speed and battery. Combined that with CPU sleeper app. I get around 14 hrs.

you can also just ignore it. it doesn't mean you have less battery time. it is just a measure of voltage. pretty meaningless. you'll notice that when that happens it will slow decreasing further and even increase as it continues to measure voltage.

See if you can get the OTA update to FH13. I had my E4GT for about a week and then the OTA update to FH13 came down. The battery life was much better than FF18.

Honestly? Skip FH13 and go straight to FI03. People are reporting MUCH better battery - at FI03 and moderate use I've burned through 43% after 8 hours - and that's with a 10 minute screen timeout! (Good thing it's doing better, I forgot the charge cable today)

So you have had that issue on FI03?
hell i installed FI03 already im going to check out if its better
do you recomend me to still with ICS or go back to GB?
Try fully charging and draining a few times..
I (sadly) had GB till last week, and had very good bat. life. few days ago, playing catchup, I flashed few ISC and JB roms, and my bat. life was absolutely horrible. To top it off, I didn't even have a wall charger, anyway today I think I'm getting better battery life. Few things about what i did,
Im on Dark_Knight's CM10 RC0, FH13, the one's I had before were CM9 (don rem which), CM10 alpha 5.3, and the official OTA update from sprint (4.0.4 - with i think it was FH13 modem)
Fully charged, wiped battery cache and left it to charge
Charged it with wall-plug
You might just need to fully charge it with the wall, I kinda overcharged it, without unplugging it, and It was on 99% for longer than an hour. Which means the battery reporting was off. I think the problem might have been that it didnt really fully charge eventhough it said bat. was 100%.
*I know people say batt. cache wipes doesnt do anything, but I am pretty sure from what I have seen it atleast doesn't get reset when you charge 100% as some claims..

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?
Sent from my HTC One X using xda app-developers app
Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.
