ODIn - Samsung Epic 4G Touch

I finally took the plunge and flashed my phone using the Odin method from this forum. First off i usually use swype for my keyboard and i get a error message me telling me the file can't be found and need to select another input method.
My next issue is when i charge my battery. I have noticed that the battery icon on top will tell me i have 70 per cent battery life left when i plug it in to charge it shows 90% i am running orginal samsung stock batery.
I really dont see much different in ICS . I have the same wallpaper didnt really notice any different programs for this. What am i missing? Where can i download custom roms for my rooted phone and what should i download

What exactly did you flash to the phone?
The battery thing is a little unusual. It could be because you just flashed a new rom and a reboot may fix that. Of course, it takes a couple of days for the battery life to settle in also whenever a new rom is flashed to our phones anyway.

I would download better battery app from market also battery calibration fully charge battery and calibrate battery. Use better battery for status of battery. For a nice clean themed rom try wicked sensation. Daze did a very great job on his rom, and I made it my daily rom.

[Q] Why is my battery so bad on ICS? Can I downgrade to GB?

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
Day one calk FE22: https://www.dropbox.com/s/0lroppsxl1bzbup/2012-06-07 18.14.04.png
Battery 2nd: https://www.dropbox.com/s/pttz5fla4us8evk/2012-06-07 18.14.08.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.

[Q]Battery Draining 20% in 15minutes

Hey everyone, I've tried posting this in the battery life thread but I've gotten no help in resolving this issue. This morning I unplugged the phone from the charger(I leave it plugged in overnight) and the phone dropped 20 perecent of the battery in under 15 minutes. At this point the only thing i was doing with the phone was checking a text message I had recieved.
I have optimized my phone so that I it only updates email and many other services manually but regardless a 20 percent drop in 15 minutes is not acceptable. I have calibrated my battery using the battery calibration app which hasn't worked. I have rooted my phone and am currently using the stock bell rom. Additionally, I am also using nova launcher on my phone and that is about it. The only strange thing that I've done to my phone is use a blackberry charger to charge my battery but I don't think this is the issue.
At this point I am beyond frustrated with this device need a solution now or I'll have to take it in to get fixed. Does granting root access void my warrenty? Do I need to unroot before I go to bell. I will post images of my phone stats in the next post.
thank you in advance for your help.

Before you send it in or take it somewhere, download" Better Battery Stats" and see if you can target where the drain is coming from. And yes, you will need to return to stock but before you do you will need to run the triangle away app. That will reduce your flash counter to 0. I'm betting you will be able to find out the problem with Better Battery Stats though. Check your PM's. I sent you something helpful that I didn't wanna post on here.

I don't know what Kernel I'm using but I am using the stock Jellybean rom. I've basically just given myself root access and installed the latest stock firmware. I am using my original charger(plugged into the wall) and last night i left my phone plugged in for over 8 hours so its definitely getting a full charge.
When I was am girlfriends house I used her dads blackberry charger to charge my phone but I don't think that would have wrecked the battery in such a way. I have noticed that the battery seems to draing very rapidly up until about 75% at which point battery consumption returns to normal. I can try charging my phone whilst plugged into my pc if you think that maybe make a difference.

Ok. I gotcha. The charger thing only matters if you use the wrong charger all the time. It doesn't charge it properly. It doesn't do any permanent damage that I know of. I would advise using the Samsung charger whenever possible. Anyways, let your battery drain all the way down to 0 til the phone shuts itself off then charge it all the way back to %100 without taking it off the charger. This should recalibrate your battery. It just got knocked outta wack. It happens sometimes. Let me know if this works. And by the way, you're probably running the stock kernel. You can always get that info by going to settings/about device. Let me know if this helped.

I have a friend who had the same problem, he had to get his phone turned in because his motherboard was malfunctioning.
He ended up getting a full phone replacement and hasn't had the problem since.
If you continue to have this issue I'd definitely get it looked at by your providers retail location.
edit: If you root you will want to avoid tripping the flash counter, which from what I've seen lately is very difficult.
Telus flat out told me in the store that they don't even care if it's rommed and have asked me what I like to use for roms etc which is nice, I don't know if Bell is as lenient.
Best of luck.

The previously mentioned %68 after 5 hours is pretty typical of what I get running stock kernel with ParanoidKANGdroid 1.40. That's while I'm at work, so I'm usually connected to WiFi, on silent, with most of my usage during that time being texting, but I do usually play games on my lunch. I have thought that was a bit excessive drain, so yesterday I set up CPU Editor and set my maximum CPU frequency to 702 MHz. I got pretty close to the same drain.
Today so far, I have the stats uploaded, and that seems much better to me so far.

Thanks for posting this thread, I'm having the exact same problem. It's been an interesting go for me.
Some times it does it and other times it doesn't.
I'm using cyanogenmod nightly from 1.3.13 with the latest ktoonez kernel and I've noticed that today, it's sucking battery more than ever. I'll attach a screenshot, but I think there might be something with the charger as mentioned earlier in the thread. When I charge it at night, I'm charging it off an old blackberry micro usb cable with a generic AC to usb plug.
I'm going to let this thing drain out and die and charge it back up to 100% and see if that works for me.
Does kernel make a big difference for battery life? For that matter, what are the main advantages of different kernels?

It definitely helped me. The main advantages that I see with running the kernel that I use is the ability to undervolt & overclock it. This will allow you to run the same frequency that you normally would but at a lower voltage therefore reducing heat & battery consumption. Google it & do some reading & educate yourself on it before you make your decision. I am glad that I decided to do it.

Yes I think AOKP will allow you to change some settings around. It will allow you to set you min/max clock speed & your gov & scheduler. A custom kernel will give you different gov, schedulers, & different min/max speeds. I use Ktoonsez's kernel & it comes packaged with an app called Ktweaker. He advises to use this app to control your kernel settings. I don't think that they will apply properly if you don't. Also you can undervolt with Ktweaker.

[Q] What ROM do you think is the best on battery life?

I have a ROMed Galaxy Note 2 and the battery life is amazing. My son on the other hand has a stock Galaxy S3 and it's the worst battery life I've ever witnessed. It's the typical draining while in standby issue reported by many S3 users. Bottom line, his phone is getting a ROM tonight before this phone melts down. Problem is, which one do I choose? There are so many and it would take me months to read thru every post to determine which one is right for him. So for now I'm going to focus on what really matters most, battery life.
Which ROM have you read about or used that you feel is battery life winner?
Thank you.

We are lucky to have MANY great ROM's out there. There are so many great devs here that go out of their ways to make the experience better. I highly suggest trying as many as you can, because each phone, after much experience with my ROM's, are different. Make a nandroid backup and try a bunch! What I'm getting at is that there are too many well made ROM's here to pick one. Flash away. Oh and make sure you turn off google now cards and locations...that will drain your battery like no other on this phone. Best of luck!

For longest time I was swearing at CM10 / CM10.1 and than I found a thread about what affect battery and now both TW and CM based roms that I use are about the same...
To get great battery life follow the simple rules:
- stay away from colour. The darker the theme / icons are the better the battery life. Some go as far as to get inverted gapps...
- no live wall paper. It will affect battery life... yes, the darker the wallpaper the better the battery life...
- turn off GPS , bluetooth , nfc and everything else that you don't need... turn it back on when you need it...
I have 15 toggle mod and I even turn off data when I don't need it. (I turn it back on once every couple of hours to get e-mail and notifications... than turn it back off... this also prevents rouge apps from dialling back home to mothership...)
- if I travel from one location to the other I toggle airplane mode on and off... this forces modem to look for strongest tower... the strogner the tower the less power you need... hence less battery consumption...
- Use Ti Backup on roted rom... unistall what you obviously don't use..
- Google apps that run that you don't know what they do... stop or unistall those that you don't need...
- Use fierwall... block everything that doesn't need to talk to internet ... less you use antenna longer the battery life...
Also, if going to new ROM wipe battery stats and let battery fully discharge couple of times. This helps as well...
Follow these simple rules and don't be surprised if your battery life doubles regardless of the rom...

While most of this makes sense, I have to disagree with discharging the battery fully. This actually reduces battery life drastically.

I agree but idea is that you let the kernel optimize it by itself.
So you do this only a few times on new rom and that's it...
As for myself I tend to plug in the S3 to charge as soon as I hit 60-70%...
(whenever I can of course - i actually keep one charger at home and one at work)
SIDENOTE:
Forgot to mention the widgets... to me they're just short-cuts and if you set them for automatic update (weather being prime example) they'll just waist battery and bandwith... (it takes about 1 sec to turn on the data from 15 toggle mod and 1 more to start the app I want updated - email weather whatever... to me this is a small price to pay for extended bat life...)
If I may toot my own horn, how about this guy getting four days from one charge with my ROM and ktoonz's kernel? http://forum.xda-developers.com/showpost.php?p=36384974&postcount=95
Your mileage may vary but I usually get about a day and a half or two days from one charge with the stock kernel that's included in the ROM

4.1.2 battery life terrible

I can't possibly be the first one to create a thread about this. Yet I have been searching and can't find it. So here I go.
I obviously have a T-mobile GS3 T-999. I was on stock unrooted 4.1.1 just fine with great battery life. I updated to 4.1.2 stock unrooted and now my battery life is terrible. I can't even come close to lasting all day like I could before. My habits haven't changed. I haven't installed anything else since they update. I have rebooted and power cycled several times, no change.
Anyone else have a reduction in battery life since upgrading to 4.1.2? Is there anything I can do without going beyond the usual? I have been using power save mode since I bought the phone. So it was that way before and after the update.
Rooting and flashing a custom Rom will increase battery life tremendously. If you don't want to root then disable all the bloat ware. This will speed up phone and increase battery.
Sent from my SGH-T999 using xda app-developers app
Haven't been able to get awesome battery life on my end either. Played with all kernels available even going backwards to kernels I know gave good life on 4.1.1... Something internal is causing it, it seems. I don't get wake locks that I don't cause my self, just battery drops faster now compared to what it did before.

I suspect that the premium suite, which added multi window and a bunch of new apps and features, is probably causing the increased battery usage. With the increasing amount of bloat Samsung is stuffing into their ROMs, decreased battery life is expected.
The life on 4.1.2 is terrible over all not sure why best bet would be routing flashing a custom rom or you could try playing with kernels but those are tricky business. I feel 4.1.1 Roms get the best battery though I'm on 4.2 and not very good battery life on that either

I flashed a number of 4.1.2 roms and found out that for some reason the cpu stays at the max clock constantly. No clue why.. Maybe that's the issue?
Doesn't matter to me at the end since I got a lemon
Yeah I'm not really liking it much. I would do better on 4.1.1
These are my results on Stockorama v2. Stock Kernel.
I don't think it's that bad but I wish it was better.

That's actually quite good compared to what I get with the latest CM 10.1 nightly.

That's terrible on both accounts lol. I usually get 18 hours with that battery time. I remove all the bloat I mean all of it. I have maybe 20 apps total in my app drawer, I disable all the sync besides contacts, gmail, and calender. But still have drain. On stock kernel it was bad and deep sleep was hardly achieved with no apps running in the back ground. I'm gonna Odin root66 md5, tomorrow and see if it helps. Other then that I'm going back to 4.1.1. I'll report back tomorrow or Friday with results.

Well, I don't plan on rooting or using a custom rom any time soon. But I am hoping to find out what I can tweak to get my battery life back to what it was. I am guessing I don't have the option to go back to 4.1.2 using Kies. And I hear that 4.2 has poor battery life as well, so now I don't have that to look forward too either.
I'm on Stockorama V1 and still had 50% battery when I went to bed this morning (I work nights). The first day after I flashed it the battery was pretty bad, mostly due to wake locks from the Media Server, but that was an easy fix with an app from the Market. I would actually say my battery life is a little bit better now than it was on 4.1.1.

I don't know if Sammy ever solved it, but iwith past updates the media scanner would hang up and drain batteries quick. Some had their phones heat up.
Another culprit can be that when going to a different android version, it may handle some data differently, causing hang ups when it runs into something they didn't plan for.
In either of these cases, its best to do a full wipe (backup first) and then reinstall your apps. Don't restore them from backup as that's just like not wiping in the first place.
Then wherever possible, import your data through the app itself. Not many do this but some do. Contacts is one.
I know it can be a pain, but it can help a lot. Plus you wind up cleaning out stuff you don't use or need anymore.
I always wipe data when updating , unless its to the same android version (4.1.1 to 4.1.1). Going to 4.1.2 shouldn't be to big a deal, but you never know.
Another thing to try:
If you verify media server/scanner is a oroblem, copy all your music, pics, vids, etc to your computer and wioe it from the phone. Then reboot and wait a few min to see if its acting ok. Then copy your files back, wait a few min and reboot again. Hopefully it'll calm down after this.
Hope that's more helpful than confusing!

You wonder why carriers take so long to release an update because usually people would start complaining. It's not 4.1 so don't expect the same thing, usually when there's an update things are the never the same. It was the same thing the jump from ics to jelly bean, when creating voltages for batteries I don't think companies anticipate all the extra stuff a update can bring this is still kinda of an ics phone.

My battery life went up so much. I'm on stock but rooted. I usually drain my battery before the day is over. Now I'm going over a full day.
Sent from my SGH-T999 using xda app-developers app
I was able to get 32 hours on average with CM 10.1 and KTunez kernel. I recently switched to the Stock latest TW and I'm seeing 22-24 hours with the KTunez kernel. I am rooted and removed all the bloatware.
I'm running stock rooted for now. I hardly have even noticed any battery drain on my phone. Stock Battery, nothing really battery-heavy, no customer kernels. However I dont really see the use of this Sidebar thing. Its like
HAY GUIZ LETS PUT THE UBUNTU UNITY BAR ON ANDROID HUEHUEHUEHUE SO CLEVER!
But in all seriousness, I seem to be running just fine. So I cant really vouch for Multiwindow being the culprit. I may run some tests though.
I don't remember what it was before. But usually by the time I went to bed, it was in the 40's and sometimes the 30's if it was a heavy day for me. Now it drops into the teens.
I see that as of today, the phone has been discharging for just under 4 hours and is already at 88%. And I haven't even used the phone in any way today before checking it right now. Shows "Google Services" as 41% of the battery use. But that only shows CPU total at 33 seconds. Next item is "Device Idle" at 15%. So I don't understand why it's down to 87% in 4 hours of basically doing nothing.
Though I don't think that info alone means anything to me right now as I don't recall what that info was like on 4.1.1, only that my battery % by bedtime is significantly lower than when on 4.1.1
I was just curious how many other Tmobile people experienced the same thing when going from 4.1.1 to 4.1.2. All stock that is.
I don't have time to deal with wiping the phone clean and starting over. But I may try that someday. My phone never gets hot and I never see the CPU getting much use at any given time.
I do wonder about facebook though. I think it also did an update of it's own around the same time I did the 4.1.2 update. I will check into that.
I have found battery life to be about the same, at first it wasn't that great but now I was able to get over 2 days with minimal use 4g on all day. With normal I use I still get better battery life that 4.1.1

I am confused. So it wasn't good and then it just became good over time? Or have you made some setting changes?

Well when I first updated it was stock and battery life didn't seem very good but I've since flashed a custom rom and all is well. Also I think stock rom got better battery with use, maybe had to settle in? But within 3 days of using 4.1.2 my battery was back to normal again.

Battery Life TERRIBLY sucks

My battery life on 4.3 stock was 8 hours screen time (half brightness I believe)
Rooted and flashed a custom rom and kernel 7hr30min screen time
Flashed different kernels dropped to 6hr max screen time (without factory reset)
After installing Xposed and many many modules the screen time kept dropping to like 5hr to 6hr
Updated to KitKat and rooted 4:30min to 5 HOUR MAX screen time PLUS phone got hot ALOT OF TIMES
***RIGHT NOW*** Flashed a custom ROM HyperDrive with Colonel X latest and Compulsion latest BOTH 3hr30min to 4hr30min MAX screen on (EVEN with Jovy23's kernel settings that got him AMAZING battery life with ConservativeX governor - It still did not fix the issue not even a little - I still like Compulsion which was awesome when I was on jellybean) :'(
Same settings for all the above set ups. Whenever I flash a ROM I ALWAYS clean flash and I DO NOT have Titanium Backup NOR do I use any other restoration app. I tried to clear and format every partition. I formatted SD card. SAME issue. I am frustrated by the battery life; it DOES NOT last me a day when on stock unrooted it was easily 8 hours. Also I do not use auto-brightness cuz the sensor uses more battery, so it was on half-brightness)
Someone please help me. The worst thing about a phone is the battery life. I usually browse Chrome and Facebook and for these simple tasks my battery dies quickly (WTH?!). I can't even think about gaming (and I REALLY want to GAME), but I know the battery life would die so much.
Is my phone defective? I tripped Knox. I already had a warranty replacement in like the first 2 weeks cuz of Knox issues stock. WTH is wrong with my phone. I want to format and clean EVERY SINGLE THING on my phone to get it the 8 hours screen on time I used to get. No matter what I do my battery life right now WILL NOT go above 4hr30min to 5hrs screen on. I used to watch Netflix for quite a while back on my stock Jellybean / rooted Jellybean days, now it dies extremely fast.
What should I do? I was thinking of flashing AOSP so it cleans up whatever Touchwiz and Samsung related is on my phone and then re-flash touchwiz so everything is set up correctly. I tried to use the mega-wipe script for a certain Note 3 model but it stopped at like 10% to 20%, so that route did not go well (I manually wiped everything data, internal, etc, before flashing many ROMs and this problem persisted).
I cannot do anything good on my phone until this issue is fixed. I hate clean-flashing and setting up things (I think titanium backup and stuff screws up your system) all the time. I cannot game, I cannot download good apps, I cannot do anything that is not online based or can be backed up online. Apparently my battery state is stated as "good" on the system.
"... All of this in under one day..." Give it a few cycles over the next few days. It'll change. I've been using HyperDrive with ColonelX with the conservative governor tweaked for performance. Can't really say much about the battery life since I have the 10000mAh battery.

Dude, if it's all under one day. You need to let a ROM and kernel set In. You can't drive a car without wheels. Just give it 2 or 3 days it will begin to get better. That's what I think too but I give it some days to stabilised if you will . Then my battery goes from normal to good to great. It won't right away start getting great battery life. Unless you have a kernel your phone don't like and flash another it does like battery life improvements where almost instant at least in my case. Like now I'm getting Ok battery life. It's not the best. But it holds. I might switch kernels tonight to spice things up.

I meant the right now part is under a few days. Idk why i said all under one day (it was late night). This has beena problem since February at least
Trust me I know you have to let a ROM and Kernel set in but my phone keeps working harder than its supposed to. Screen off battery is good, so wake locks are not the problem. The problem is cpu wise something is messed up that it puts my cpu to drain huge amounta of battery
Even you tried another or different ROM still happens?

Yes tried many roms and many kernels with many governors... i suspect its my battery but my battery state is good for some reason
I had this issue but it went away when I updated my phone to 4.2.2

The rom and kernels might be the one messing your battery life, since your battery is in good state, but why not try replacing a battery if you have an extra and see the results...

How do you find that out?
There is an app that can report this value. The premise is that certain cpu's have different values which indicate how the cpu will perform. The problem is, the same cpu can over time end up reporting different values which pretty much means it is not really a set hardware value and most likely means nothing.
You can find the large thread about it if you look, but it was pretty much debunked as a really value at the time.
first download the new rom http://forum.xda-developers.com/showthread.php?t=2709867
put it on a sd card
make sure you have a custom recovery
1 go to setting back up and recovery do a reset from there
2 let the reset be done then restart the phone and go to recovery
from recovery do a full wipe factory restet
3 install the zip from the sd card
4 pick the apps you want with aroma installer and install compulsion kernel
4 finish installation and boot up
set up the phone and enjoy it bro.....

Nice battery life enhancer.
You have to let the rom settle before you can get accurate battery life akin to the rom and kernel. Trust me I know this as a fact. I have been flashing roms like crazy since the days of the Samsung admire and the rom takes days to settle.

Yes he let it settle but still no good for him.
I have the same problem. 4.3 battery life was 6 hours screen time, 4.4 down to 3 hours screen time. Note 3 used to be my ideal, perfect phone. 4.4 ruined that.

You made sure to toggle allows allow scanning off?
Toggle either power-saving or GPS only under location?
Power saving mode if applicable?
Turning of haptic feedback?
The always allow scanning seems to be the number one battery killer for me. I turned that off and noticed immediately better battery life. Almost akin to an extra minute per one percent, which adds up.

Yep, did all that stuff from day 1 back on 4.3. Updating to 4.4 was the most frustrating thing ever. Many people here report great battery life with 4.4, but many like myself had it slashed in half upon upgrading. It ruined an otherwise perfect phone.
