Problems with Epic

I'm on ec05 un rooted.
I've noticed a problem that started a few months ago. Before I get into that...some things to know:
I have 5 batteries. 1 stock and 4 aftermarket.
One issue I have is battery drain. If I'm not on wifi then I get between 2-4 hours. With wifi it is 5-7.
Whenever I change the battery it is a toss up as to whether all of my apps will load. I have rebooted 5 times today within a 30 min period. All the apps still haven't loaded and battery life dropped 20%. I have tried using the keys to reboot and also taking the battery out.
The phone will also get hot when not on wifi.
Any suggestions on how to fix? I have tried factory reset and it doesn't fix it.

If you're already willing to factory reset, you might as well Odin back fresh and see if it helps. Unfortunately root is needed to calibrate the battery in traditional ways.

If you have 5 batteries and have to swap out every 5 hours then your probably on your phone all day.

Are you just pulling the battery or letting it power down? I know stock has journaling on which protects you from if the battery gets pulled but after o long it ill catch up and do it mine has but I get why better battery life then that. My wifi on I will get about 15 hour with little bit of use but I will get about 6 to 7. When running pandora at work the whole time and maybe mess around with it for 30 mins. Also make sure you back out of everything

I would bet you've got some app installed that is constantly running in the background, constantly connecting and downloading data and killing the battery. Since WiFi uses less power than 3G you get better battery life on Wifi, but if you are constantly syncing and downloading you are going to kill the battery.
If you go into settings>accounts and sync and look at what's syncing it may give you a start. You could also go int settings>about phone>battery use and see what's using the most power.

The only thing that is set to sync is gmail.
The display is using 91% of the battery. Even if I don't use my phone much during the day, the display still shows 90% or higher.

The display is always the biggest drain. That is based on 100% of what you have used. If your battery is warm while not on wifi you are losing 3G and your phone is constantly trying to connect to sync. Put it in airplane mode for an hour and see how the drain is. My guess is a tower is down near you or under maintenance.

When wifi is on means 3g is off. And cdma 3g uses ALOT of battery because is has no type of "sleep mode" meaning it is on 24/7 and when you do use it it is a battery hog because it also uses a lot to power the cdma bands. Just another cheap flaw in the life of sprint.
So when you are not on wifi turn off 3g.

battery?

im running the stable cm7 release and my battery life is terrible. i followed the guide on the forums here on fixing your battery life, charging to 100% pull battery put back in instal battery fix etc and overnight (short 5 hour night btw) i lost over 25% of my battery life, doing nothing ! wifi off data was on but i only recieved one or two emails all night. is this normal for cm7?
i read about how people are getting 20+ hours battery life while using their phone, if i leave my charger at home and go to work my phone is DEAD halfway through and all i use it for is the occasional phone call mabye 5-10 texts throughout the day and an email or two... how can i fix this?

I read somewhere that if you flash another ROM with battery not fully charged, it messes up calibration and you have to calibrate again. I am still with stock Blur just because I read so many issues with so many people about batteries
I hope you can get it figured out.

anybody?
is anybody else having battery life issues with cm7? if not did you do something to fix it? i have no idea what to do, the phone pretty much has to be tethered to a charger or it gets drained ridiculously fast. If i hang out with a few friends and use my phone during it i literally have to stop using it after around an hour or so because the battery's about to die.
Is there a certain rom with exceptional battery life that i can try to see if mabye its a hardware related issue? i seem to remember having horrible battery life for the day? or so that i was running stock ATT gingerbread.

I use Aura 1.2.2.2 (debloat) and get average battery life. Comparable to what I got before I installed third party ROM. If you want to try that one and see if its just CM then give it a go.
I had a battery problem after flashing to CM with a previous phone (OG Droid) but it was because I flashed while I had the phone plugged into the charger. It took a while to get it back to normal.
I doubt its CM. I dont know if its something draining your battery in the background or if its a result of weird calibration due to the flash.

my battery life has never been hte greatest but recently i got it working really well
I use the latest weekly build of CM7 and here is what i did
upon fresh install:
wipe battery stats
THEN:
kill battery
charge as far as it will go
clear battery stats (use battery calibration app)
take out battery
wait to reboot(missing battery)
put it back in
let it charge for 2hrs
reboot and unplug
kill the battery
charge to 100% while off (no interuptions)
Enjoy!
i have found that the more cycles my battery goes through 100-0-100
the better it gets
these steps almost tripled my battery life (along with Weekly 3)

there is a bug some people report with CM7 about the suspend process. (i have it, you can search "suspend" in the CM7 thread and see others are as well) load up the app betterbatterystats (there is a thread on xda that has the apk) and see if you have that bug.

I'm on nightly 20 having good battery life

I'm a victim of the suspend process bug
had to flash something else, using ALIEN for now and battery is pretty good
Sent from my MB860 using XDA App

i installed betterybatterystats as you guys recommended and im not entirely sure how to read it but the suspend process shows at the top of the list so i assume thats the process which is eating up my battery? Is there a fix for this? i do like cm7 but if its the rom which is causing my battery life issues ill have to wave goodbye. Does this suspend process but happen on the weekly / nightly builds as well?

I was having horrible battery life as well. I froze some apps that I downloaded from the market and that helped a little bit but what gave me 20+ hours of battery life is the new UK orange Radio that has recently been released. I wanted to flash it since I am using an Orange UK phone and see if it improves my wifi connection, etc....
Reddy flashing a radio appropriate to your device and see if it helps.

I had it on stable, and am on weekly 3 right now. I'm probably going to switch back to a blur rom soon..
Sent from my MB860 using XDA App

My battery blows with CM7. My phone has the suspend bug and nothing fixes it. I tried a fastboot wipe and clean install of the latest stable as well as nightly #20. I've tried several kernels, I'm currently running a screen off profile of 216-216 on the 1.0ghz kernel and I'm undervolted to the max just to make it thru the day.
I'm getting the nexus prime or the iPhone 5 next... which ever is released first.

Recent increased battery drain

Has anyone else been experiencing increased battery drain this past week? No matter what rom i have installed, apps or how often i wipe the battery stats the battery drain doesnt slow. I have watchdog going for the past couple of days to try and track the problem but its not showing any runaway programs.

Maybe try a new battery.
Sent from my HTC Glacier using xda premium

I have, or in the sense that something likes to keep my CPU awake for long stretches when the phone is idle. Noticed it during the sale but haven't been able to find what it is, as I don't have many apps added to my phone (most goes on my tabbook). Excluding application updates the only thing left I can figure to do, is switch back to Zeam from ADWLauncher Ex.

Yeah, on stock, ADW really drained my battery. It works best on CM7 or rooted. Sorry.

Could be a couple things, maybe try a different radio or maybe another battery? Or maybe set a screen-off profile in setcpu 368 min/max conservative? What voltage is your battery at full charge? Mines usually around 4207mV

Has the same problem, even in airplane mode...saw this:
http://forum.xda-developers.com/showthread.php?t=1390405
a couple days ago and followed the 2nd to last post and battery life has been great again...

Not sure what eqjunkie829 has but I'm on CM 7.1.0 and don't have the Amazonlet running. Initially I thought it might be dry commo from Swiftkey X (I usually have mobile data switched off and wifi on when desired). What apps are useful for accounting? I.e. more precisely seeing who used what than the battery thing in settings.

more than usual? no never

turn your display brightness down, turn off gps. they usually drain your battery. have you tried using juice defender? paired with the ics 5.1 beta, i get great battery life. 9 hours in and my battery was still at 60%.

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

+1 that app will tell you exactly what's bogging down your cpu, and which apps prevent proper deep sleep mode.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.
Using GT-I9000 my sent Tapatalk 2 from.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

Idea
I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.
Since I can't put my signature for unknown reasons...(Maybe because I just created an account since I did not want my old one)

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!

Something wrong?

I've tried a large amount of ROMs by now and I'm cosistantly having these issues with my battery. I'm noticing a correlation between battery and WiFi seeing that WiFi destroys it every time I use it...is there something wrong with my phone? Battery? Should I stop using agat and ktoonz kernel? I'm confused...I'm not OCd or anything with my kernel either

If you have a battery monitor (such as GSam or BetterBatteryStats, etc) take some screenshots and post em' so we can get more info.

Yes, I noticed that WIFI kills the battery life too. That probably because, it constantly scans to try to find and connect to a hot spot of TWCWIFI. I have to make sure to turn off the WIFI after use.

Hmmmm. There are a number of rooted apps that will kill unnecessary apps from sucking the life oitta your battery.
Use Greenify. Its a pretty cool app that deff helps out.
Obviously make sure Power Saving Mode is on. Make sure to turn off anything youre not using.
ALSO. Something many people don't know...Whenever I get a new phone and or battery. I make sure..and this is important...I charge the battery ALL the way up without messing with it. Then when its good and juiced up. Use the battery normally. But use it ALL the way til your phone dies. Literally. Then...charge it ALL the way back up.
Repeat these steps a good 3-4 times. Batteries have memory in them. If you charge up a new battery to say 75% and take it off and let it drain..then charge it back up. It'll think that 75% is 100%. Thats why its crucial to do those steps a good handful of times.
I guess you can also set your brightness level to auto. Get a cleanup app. Clean Master is a good one. It even boosts memory too by clearing up random files.

I tried greenify but like as we speak, I'm on the charger with WiFi on and the battery is still draining....like is my phone screwed up?

Yes, you should. I am always amused that people will take a perfectly good device, modify it completely, and then wonder why they are having issues. ODIN back to stock rooted and don't fix what's not broken. Needless to say, I have no battery drain issues with my device. On my old S3, I used to do what you do, including running kernels by the same devs you mentioned. What I found was that I would spend hours backing up, flashing, restoring, configuring, etc, and I would be left with a device that ran like crap with piss-poor battery life. Nothing custom lasted more than 48 hours on my old S3 and nothing custom has even been flashed to my S4. No need for it.
I do notice that sometimes I get more WiFi battery drain than even on LTE. That has to do with the signal strength of the WiFi vs LTE. A weak wifi signal will drain your battery more than normal, that goes for any device.

Give us some screenshots brotha so we can help diagnose the problem.
