I can tell you i've done this and havn't noticed any difference in battery change. I use skyraider 2.5.2 and KK #3 kernel. Bump Charge and work gets me well through the day with moderate use.

I've done this a few times too and haven't it do anything.

ive noticed a change when i charged fully while the phone was on and the light turned green then just rebooted in recovery and wiping battery stats i do it every time i flash a new kernel i mean my opinion i have noticed better battery life doing this process

[Q] Question about Rooting the epic?

Any major benefits to it right now beside the major LoS issue. OC is not really a key factor in it for me with this phone since its fast anyway. I know custom roms usually always have a major benefit towards what they can do. but is it really worth it at this point. i have not once had any LoS issues, may just battery
PS. i just got my phone yesterday so i dont know much about samsung products. im use to rooting with HTC devices from the start of the hero, Evo, Evo Shift.

I waited a week to root and had no LOS. Then I flashed everything I could get my hands on and still haven't had LOS. The roms that are out all seem a little smoother and faster than stock. Just make sure you wipe data/cache/dalvik and format system before you flash a rom and you should never have any issues. Returning to stock is also so easy that there aren't any real drawbacks to rooting and flashing roms or kernels. If you're happy with the way it is now I'd just give it some time and read about the roms and kernels as everything progresses. I could live with my phone stock but I hate background processes and bloatware lol.

that's what im looking for, the better battery life, but stock is surprisingly good for me right now, except battery. Does either rom support signal feeds from other towers like CM did?? just curious, highly doubtful tho.

Do you mean forced roaming like on Verizon? If so then yes you can force a prl update to the phone that will let you control roaming. And as far as battery life I run the stock pulled kernel and have it set to 500Mhz Max when the screen is off and 1ghz when on and my battery life has been great (standby times are incredible).

How do I wipe battery stats through Rogue Recovery running Calk's ROM v 2.6?

Hi guys, I tried searching through the forums to find the answer and didn't get far... I am currently running Calk's ROM v 2.6 with Rogue recovery and EL13 modem and I feel like my battery dies way faster than most other ROMS. I noticed that Rogue recovery will let you wipe battery stats, and was wondering if I can some how try to re-calibrate my battery or if there is anything that I can do to improve the battery life on this ROM. I noticed that there are some zips that I can flash on the same thread of where I got the ROM, will that work with v 2.6? Sorry I'm some what of a noob, all I know is how to flash ROMS and bring my phone back to stock. Thank you guys in advanced!

I'm using the full version of the ROM btw. I believe I'm on EL13 kernel as well...

Hello, ive asked the same question lol so Ill pass my knowlege along. From what ive learned, if youre using rouge recovery there should be an option that says wipe battery stats under wipe, but you shouldnt do that first. In order to do a full battery callibration, you need first charge your phone to as close to 100% as possible, which means you need to charge it fully while its on, turn it off and charge until it says fully charged then turn it on and charge it again.. This process shouldnt take over ten minutes after it charges the first time. im not sure why you do this but I think its too ensure it fully charges. Once you do that.. Go into recovery mode and go to wipe/wipe battery stats, reboot and make sure to leave it off the charger until it dies completely, use as normal, then charge fully without interruption. Then youre done.. Hope this helped brah

There is a battery calibration app in the market as well. Plus you need at least two full discharge cycles with a new rom/kernel to really start gauging anything...

Thank you, thank you! I'm going to give it a try... I will post again with my findings.... Oh, btw I flashed the 100mv undervolt zip that Calk posted as well and it seems to drain a little slower...

Major battery drain on Calks E4GT 1.6 ?

I flashed calks 1.6 the other day and noticed big battery drain. I reflashed today just to make sure. Drains about 20% an hour in my pocket. As soon as I start using it, it drains so fast i can watch the percent countdown lol. It dropped 20% posting this. Its also charging weird. When I plugged it in it was at 65% and in 20 min it was full. This is very odd because I used this rom many times and it had great battery life. Anyone else experience anything like this on their E4GT ?

Must be a bad battery, how long have you have your battery? also have you removed battery stats?
Try using phone at maxxed out power until it drops to 0% then recharge battery until full, I recommend overnight.
And get back to me...

I don't think its the battery unless it went bad overnight lol. It was fine the other day. Something weird happened a few weeks ago i dont know if it has anything to do with this but I flashed a rom that I had flashed before many times (phantoms blazer ics) and it aborted the install. I reset my phone with sfhubs one-click , formatted it,
And tried flashing a new rom and same thing. I posted about it in Q&A and no one really helped out too much. I tried everything new downloads, new kernels you name it I tried it. And it still happened, everything I tried, to flash got aborted on el26. It was so odd cause it was doing it to old downloaded roms and the el26 I've been using since ics . I could flash a gb rom in el29 but as soon as a flashed el26 and tried flashing something it would happen again. The only thing that would flash successfully is calks format all (every time)So I got frustrated, and i stayed on stock rooted el29 for a week or 2 since no one would help. The other day I figured id try again off a fresh reset and new downloads, and it went fine, I flashed a few roms but decided to go back to calks 1.6 . And now the battery issue ? Should I wipe battery stats? I don't really know what that does. Btw I reflashed and it didn't solve anything, still draining. I will try running it down and charging overnight. Any other suggestions?

Btw I've had this phone with the same battery for about 5 months now
Sent from my SPH-D710 using xda app-developers app

Did you flash back to gb ?
Or flash another Rom but imo its probably due to an app installed that's not ready for ics

only thing I can think of is I downloaded the T.5.3.0.32 VVM for ICS. The one I downloaded is supposed to safe for ICS. You think that could be draining my battery?

Time to upgrade to a released rom....
Calk's 1.6 is based on old, unreleased code and isn't supported. Calkulin has moved on and no longer dev'ing for this phone.

I would like to but I liked that rom for its stability and battery life, but my question is why is my battery life bad now. Ive ran this same rom (same download) before and it was great. Why the bad battery life all of a sudden?

Please help. Poor battery life. (Please see inside)

instead of flooding all other threads I thought of creating one of my own.
I am running ARHD 8.1 with faux kernel 006. Previously I was on stock kernel with ARHD but due to poor battery life I flashed faux kernel. With gsam battery monitor I saw that my HOX kernel is consuming 40% of battery. After flashing the kernel it remained the same. What is the matter I don't know. Is this the reason of poor battery life? This is my screenshot:
I also
Installed system tuner. The CPU is always running at 1ghz and doesn't allow me to change it. What could be the problem. I am totally messed up.

I noticed that you seem to have flashed and done a lot of mods to your phone.
Try flashing it back to stock, leave it that way for a week and let it stabilize.
You're doing too much expecting magic instantly.

Thanks but how to flash it back to stock? And does HOX automatically turns on when fully charged? It happened to me everything I charged my device when it was on.
Should I revert back to stock or should I wait for a few days with ARHD+faux kernel?
Btw I have installed system tuner. Any settings you recommend to save up more juice? I am a total noon with all these.don't wanna duck up my device again. I am leaving with full charged. Let's see how it goes.
P.S. just checked the battery consumption and these are the stats:
Kernel-42%
System(HTC launcher)-9.2%
Internet-2.3%
Charge is draining by 1% every 30 secs. Wow.

I use watchdog to see what's using the cpu and causing battery drain. Maybe try that app?
I agree with the poster above- go back to stock and wait it out..
If all fails then you might even have a faulty battery which is covered under warranty, but because of unlocked bootloader its risky trying to claim it.

Dude. Flash to stock. Don't install any battery apps. Wait one week.
All of your problems will be gone.

Oh yeah. Don't install system tuner, setcpu, anything. Leave it stock.
A lot of people go over board with apps and just bog down a good device.

can u guide me or send me a link on how to flash to stock rom and kernel

1. Find the correct RUU for your devices. They are in a stickied thread in the development section.
2. Flash stock recovery.
3. Relock boot loader. (fastboot oem lock)
4. Run the RUU.
To find the right RUU, use fastboot oem readcid and post your cid here and I'll tell you if I know the RUU. I'm not sure where to get the stock recovery, but this is what I've read others say about returning to stock.

i am on ARHD which is stock so do i need to flash stock recovery. where to get the RUU and stock recovery? even on the stock kernel with ARHD i was getting my kernel using 40%. so should i just change the rom? if so suggest me one rom
edit: i went out at 9:00a.m with 100% came home at 1:30 with only 14%. had two reboots and only1hr screen on. there cant be anything terrible than this. will charging it again and again work. also the cpu doesnt fall below 1200mhz. its between 1200 1400 and 1500. i just want good battery life whether its dual core or quadcore. charge was 20% just after 1sec it fell to 14%. app usage is 54% with 41% consumed by kernel

You might have something eating your battery. And yes, you do need to flash stock recovery in order to run an RUU.

I installed cm10 and battery life is so far good. Just on my first charge cycle and got 35% left with 2hr 18min screen on. Is it good?

You cant really tell with your first cycle, you seem to keep a rom for a couple of days complain then switch. You need to wait a week or so to let the battery settle so to speak.

That sounds great to me. I usually get to 15% with 1hr 48m screen time.

Exactly. He has made a bunch of posts over a short amount of time.
My battery life is very good on stock rooted. Run stock for a week and let it calibrate. 1 days results are meaningless.

Good or bad we don't know. Depends on usage type of data used, signal, screen brightness, auto sync and various other factors that can contribute to draining of the battery.
But that seems average anyway so not that bad.

Run arhd super wipe Install a clean rom like aosp and don't install any apps, seems like you have a rouge app do you restore apps from titanium? Use watchdog like mentioned it will alert you when any app is being naughty and running cpu when not necessary.
