[Q] FI03 Kernel using 70% of my battery. - Samsung Epic 4G Touch

I recently upgraded my E4GT to build FI03. Overall I find this release to be very stable but my battery is draining in around 4 hours. I see that the kernel is using up between 65%-70% of my battery. I'm fairly new to rooting and am wondering if there is a better kernel to use than the one I am using?
Currently my kernel is listed as:
3.0.15-1083465
[email protected] #3
SMP PREEMPT Mon Sep 3 20:27:53 KST 2012
I am running stock ROM and stock Recovery, but the phone is rooted with FI03 build IMM761.FI03.
If there is not another kernel to flash, is there something I can do to prevent the battery from draining so quick? I don't overly use the phone that much, but even if I did I should get more than 4 hours off of the battery before I have to plug it into a charger.
Thank you in advance!

Get the Universe ROM it has the cpu sleeper it really helps

I'm new to custom ROM's will installing a custom ROM delete apps and data or will everything remain as is? I've got no problem trying them out what so ever if it will help my battery life out.

Your kernel is using that much because of a wakelock. You need to find the app thats causing your phone not to deepsleep. Try betterbatterystats and cpu spy. Find the app thats is doing this and everything will be fine.

using better battery stats it appears as though wlan_wake and power management service are using almost 30% of the battery and i'm not familiar with CPU spy and exactly what I'm looking at but my phone is spending about 70-80% of the time in the 200MHz state.
as far as apps there doesn't seem to be anything out of the usual. Sometimes NetworkLocationLocator is around 10% but otherwise there's nothing else I see out of the norm.

I am on FI03 stock rooted and my kernel use is usually around 30% or less, like others have said there must be a wake lock issue.

It appears also as though com.Google.android.Location has 568 wakeups in 8 hours. I would imagine that's a gps issue.

Evo battery life....

Ok, I have an evo, running fresh gingerbread rom, and.....the battery still blows, i have tried most if the popular roms and was not impressed, i have set cpu as well, i dont see any change, im not really that good at this stuff so can somebody PLEASE hook me up with a method to make my phone last a day, roms, kernals, set cpu profiles, anything.....thank you all greatly
Sent from my PC36100 using XDA Premium App
If you are on 4g, wireless tether, playing roms, texting, and making calls, then don't expect the phone to last more than 5 hours.
First thing you need to do is start off with a fresh rom... pick your favorite so far.
Reboot
Install kernal (I like tiamat for AOSP or Netarchy for Sense but I suggest you try your own)
Reboot
Install undervolting script
Reboot
Open Google Talk>Settings>uncheck automatically log on then log off google talk
Install SetCpu
If you don't really game or anything then lower your voltages to 125 min 700ish max (you can be more aggressive if you want, but I wouldn't)
Charge phone to a 100%
reboot into recovery
wipe battery stats
Use your phone till it dies
Recharge
I think you will now have a strong phone that can last a good day depending on how you use it
If you still want to increase your battery life after all that
Lower brightness
lower the updating frequency of stocks, accounts, etc
make it a habit of turning off radios when not in use or install Juice defender
Create profile in SetCPU to lower CPU when screen off
All really good suggestions above...
but sometimes it could be just the battery it self... if all else doesn't work try another battery. The previous stock battery was horrible for me even after trying all the settings and etc. Once I got a new battery and did all the setting changes this thing is ready for anything.
What rom are you using? For the best battery life with a rom like cm7 I recommend using an SBC kernel from tiamat 4.0.2 SBC+ and give it a few days to settle in...then when your battery is low around 20% or less charge it for at least 4-6 hours while phone is sleeping..then turn off your phone while plugged in and charge for another hour..then unplug til green light goes off then plug in again til light goes green REPEAT 10 TIMES! then turn on phone while plugged in wait 2 minutes then unplug and battery is improved...do it every time you charge it from low %... this is for SBC kernels...also follow what the others said above me... I use an extended battery on conservative running it at 245 and 768 its been 12 hrs and I'm at 71% with moderate to heavy use...hope this helped

wow, seems pretty involved, ill give this a shot, im running Fresh 4.0.0.4 rom now, is there another rom i should be using otherwise? i dont use the tether, i just do the youtube thing, facebook,email text and call, nothin to extensive
Try Evodecks 1.0 or 1.2c... Very nice and everything works on it... I'm using Tiamat 4.0.2 w/ sbc, its been 23 hrs and still at 59% thats moderate use though! But just search around and eventually you'll find something that suites your taste... MIUI is also a good rom! Just my 2 cents...

WHOA it's rare to see someone say that the battery life is horrible in this forum. You should try a new fresh wipe and install, and try different kernels.
Try darksides super wipe then re install juggernaut ROM. Make sure not to run setcpu or any other cpu apps, I was having bad battery drain running setcpu.

i actually think those "battery saving" and task killer apps uses up more juice than saving ... i had juicedefender ultimate and i noticed my battery drain when it was enabled .. i deleted the app and ive noticed a great improvement on my battery .
Agree
I was also getting horrible battery life on the Juggernaut roms. I tried the bullet kernel, synergy, and faux kernels with all sorts of different ways to reduce battery consumption such as underclocking, undervolting, uninstalling bloat, and removing apps from startup. No matter what, my phone would always be dead by the time I came home from work/school (I'm usually away from home from 630am until 800pm).
I recently started using the DARKSIDE rom/kernel in the hopes that it would provide some better battery life and I am actually getting significantly longer usage times. As of right now after ~15 hours of time spent off the charger and with moderate use (~500 texts/day, XDA app, FB checking, random Internet usage), I have just under 40% battery life remaining. I must say I am very impressed with this rom and give the developer TDJ mad props.
So here's my battery life with Eugene's Macnut ROM:
Compared to this (Juggernaut 4.1 with ICS Ultimate Theme):
I run juggs with TDJ Darkside kernel, kernel makes huge diff

I am running Juggs 4.1 as well previously with the FAUX123 kernel and decided to try out TDJ's Darkside kernel. Wow, huge difference, highly recommend. I use system tuner app to adjust my speeds but main thing in system tuner app is to go into boot settings and set screen-off to powersave governor and max frequence to 800, 500 etc.
I also run easy bettery saver and that helps as well. Battery life is best I have ever had with my G2 and I got it first day it came out and have run most all of the rom's kernels on it. If you can I would suggest running TDJ's Darkside rom as well. I would but just don't want to reload again at this point.

I'll try darkside rom and see if it fixes my battery drain problem.

Thank you for this, I wasnt aware of that, what do you use to change your clockspeed when your screen is off? I recently switch from an iphone and unfortunately battery life seems to be something I have to actually think about now. I know its a faster processor and a bigger screen so I get it, I just never had to worry about turning off wifi and things like that before. I currently am running beastmod 4.2 with darkside kernel. I have 9hrs on battery at 41% with 2 hrs and 15 min of display. Im not really interested in speed at this point so I thought setcpu was a good thing to use to underclock and use less battery. Can you recommend any good alternatives or should I not bother with setcpu type apps. Thanks in advance
On darkside... Not the current one but the one before it... I think it was version 1r2 or something like that. Battery is great, better than juggernaut. I have bluetooth and Wifi on all day

They gobble up a TINY bit more CPU (probably no more than 1% throughout the entire charge) at the cost of managing your data settings. It saves juice primarily when your phone is idling. It pings, it checks data thresholds. The main idea is that it turns off 4g/wifi when you're not using it, and back on when you are. This requires a little but of CPU, but you end up having a battery that lasts much longer.
There's never be a time when you're using your phone 100% of the time on battery. There's ALWAYS idle time.

Darkside kernel questions.

So I'm currently running Juggs 5.0 and using the Darkside kernel. First day was rocky but relished it and love how smooth it is. Now am just testing the battery life. Here are much questions... 1) I was using cpu tune for my Faux kernel and used different profiles for it. Since I have Gideons script can I still do that? 2) Do you recommend it since I have this script? 3) I want my phone to not use hardly any battery when at rest or sleep, what's the best way to do this with the info I have given? Also I am using juice defender. Thanks in advance fellas !!

1) Yes but I wouldn't recommend it, its equivalent to having two CPU apps, they'll conflict, so pick one
2) See point one
3) Make sure your phone is deep sleeping, by using CPU spy and betterbatterystats to avoid app wake locks, which keep your phone from entering deep sleep and draining more battery.
For better performance all around (including deep sleep) i recommend undervolting with either faux clock or system tuner. Gideon script can also be modified to undervolt more if you read up on it a little.
As a side note, the general consensus among power users is that juice defender sucks. It drains more than it saves

Got it. So my kernel will kill the radio and etc that JD already does and save me battery? Because that is what JD is for right? Also I can't find faux clock on the market.

No, a kernel won't kill the radio. Jd sucks, and it eats up more battery than it saves. Having your radios shut off makes a smartphone dumb. Run gideons script and call it a day.

Yeah I know that but I still don't know a lot about it still. I have to read here and there and processing time for me may not be as quick as some of y'all But what I thought underclocking was is it is going below the standard speed that my phone typically does like 1242. So it would run at 1080 or whatever rate I chose. So I guess I'm wondering is when does it decide to run at whatever MHz it runs at? So the numbers I showed, is that about right or good? Again thanks

Poor battery life with juggernaut 5.0 & darkside v1 kernal

its been 3 days since i rooted my phone for the first time due to battery life issues. the first day my phone lasted for 10 hours. after a full discharge and full charge I've been experiencing horrible battery life again on medium usage. only getting 6 hours of battery life. what do you guys think would be the cause of this??? everybody is getting better battery life and mine seems to be horrible still. I don't have any out of the ordinary apps running either. do you think i need a new battery?

I have never found juggs to be a battery friendly ROM. It's a power ROM. Better for gaming, shooting live video etc. If you want the 15 to 20 hour battery some are getting then switch over to darksides ROM DIGITALWARFARE. It's powerful enough for gaming just not like juggs.
Also usage plays a roll to. If your gaming for 4 stright hours don't expect the phone to last that long because no phone will. Running Juggs with darksides kernal is kinda doesn't mix.

Download 2x battery from the market, it's done wonders for my phone and i use it with any rom i flash. Not to mention i ran that same setup for quite awhile and the maximum time out of a battery i've gotten comes using juggs 5 and v1 darkside kernel.
I'm running Juggernaut 5.0, with Eugene's Streamline kernel. I'm getting about 17hs. I'm also OCD, so I play, and tweak every setting possible. I game a lot, and usually get about 6-8 with that. It depends on a lot of factors though. I agree though, it's kind of an oxymoron to use Darkside kernel with that rom. They kind of clash.....I guess you could say, as far as battery goes anyways. I had the same issue when I used that kernel. Just my experience anyways. There's a lot of setups you could go with, so. Best to just test everything once, till you find your happy place.

what are you using? are you experiencing poor battery life as well?
Sent from my SGH-T989 using XDA
Your battery life also depends on a number of other factors as well. Do you have animations on or off? If they are on, turn them off. What brightness is your screen? I turn mine all the way down. How many widgets are you running? I don't use widgets. Is your phone constantly syncing with Facebook, Twitter etc? I only turn my sync on for Gmail and Google. Is your GPS on? I have mine off at all times. Do you stream a lot of music/videos? How many programs do you have running in the background? I make sure everything is closed or off except for the programs that need to be on. If I need to use a program/app I will open it, I don't need it constantly running shortening my battery life. Etc Etc.
I also recommend using the app Juice Defender. Yes it runs in the background at all times, but, it greatly improves battery life. I use it all the time and it's fantastic.
I typically have my phone on for 15-17hrs a day and by the time I go to bed I still have over 50% battery left. I am currently just on a stock ROM and not Juggs, but my results with Juggs were around the same as well, even with the Darkside Kernel. Peace

+1 I don't use juice defender on my device since I am happy with the battery life I get so far. However, I have Juice Defender on my wife's SGS2 with custom settings and her battery life has improved a lot. Before her phone would only last 10-12 hours with moderate use. Now she gets over 20 hours with the same usage.
Use tdjs ROM

I'm using aokp now but I found this to be the best setup for battery for me.
I recommend you try this and see if you still have this issue.
Juggernaut + synergy + juice defender on aggressive mode = awesome battery life.. awesome enough for you to have multiple MiniBaths. :banghead:

I'm running Juggernaut 5.0, with Eugene's Streamline kernel. I'm getting about 17hs. I'm also OCD, so I play, and tweak every setting possible. I game a lot, and usually get about 6-8 with that. It depends on a lot of factors though. I agree though, it's kind of an oxymoron to use Darkside kernel with that rom. They kind of clash.....I guess you could say, as far as battery goes anyways. I had the same issue when I used that kernel. Just my experience anyways. There's a lot of setups you could go with, so. Best to just test everything once, till you find your happy place.

I lost 10-15% an hour if im not on Wifi, this phone has terrible batt life when not on wifi. Could that be why?

its been 3 days since i rooted my phone for the first time due to battery life issues. the first day my phone lasted for 10 hours. after a full discharge and full charge I've been experiencing horrible battery life again on medium usage. only getting 6 hours of battery life. what do you guys think would be the cause of this??? everybody is getting better battery life and mine seems to be horrible still. I don't have any out of the ordinary apps running either. do you think i need a new battery?

Kernel with BEST BATTERY [email protected]

Hello, was wondering how what kernel has the best battery life and speed. I'm using darthstalker rom with combustion kernel o something like that but stock not the OC one. Have had bad battery life this past few days today this morning I unplugged it at 97% messed with it a little. Little xda, flipboard no videos and I'm down to 62% ridiculous.

Every phone is different even with kernel, roms, apps, etc... you have to figure out what's best for your phone.
Flash and test. What works well with mine might not with yours.
