How to increase battery life on E4GT? - Samsung Epic 4G Touch

Hi. This may seem like a noob question, but I recently switched from Stock GB28 to PAC MAN 20.1.0 and my battery drains SUPER QUICKLY. Anyone know what I can do to save some battery life??? (I under clocked to 500, BTW)

Questions go in the QA section.
Anything under 800 mhz will normally make the device unusable. I suggest not having it that low. You an use a multitude of things. DS Battery saver and Greenify together work quite nicely.

The two apps mentioned above plus THIS is what I use and I usually get 18-24 hours per charge unless I'm on my phone a lot. Screen on time is the biggest factor for battery life, especially if you're using DS and Greenify.

Not sure if that will work on his ROM.

Just have to delete 41kobridge out of the init.d before you flash on AOSP. It's in almost all of my AOSP ROMs. If there are problems delete dvfs.sh out of /system/bin, just backup before you do anything with it.

I'm hardly on my phone (I usually turn it off when I'm not on it!). I go to the Gym at about 8:00-8:30 PM so I sit at a bus stop by myself at like 10:00 PM. Which, is when this place starts lookin' like a ghost town. I'll definitely check out those apps, though! Thanks, Everyone!

I think I can see why you are experiencing bad battery life. It's not your daily routine, it's your daily driver. AOSP has always had a reputation for bad battery life on the E4GT. The lightning zap kernel may change that, however I suggest a Touchwiz based ROM. The mods have become amazing, you might not miss being on PAC.

I disagree with this statement, you just gotta tweak it right... I have four AOSP ROMs located here that I have done so, I have not done PAC Man yet, but if you wanna stay on AOSP it might be something to consider. And they are proven to increase your battery life, ask anyone that had used them.

ROM With best battery life?

Hey guys, just wondering what's a ROM/Kernel combo with the best battery life ? I'm on Stock right now and I get about 7hrs and 5 of those hours are on Standby lol. I tried Android Revolution with Trinity and got about 12 with about 6 of those hours on standby and 6 hours of very light usage. I did flash a rom the other day that gave me about 23hrs with light usage but I can't remember what it was >_<
Thanks

again?????? seriously?!!! battery life mostle depends in the kernel.
Whichever one works best on your individual phone in your unique circumstances. No one knows what will work best for you but yourself.
There's a reason mods lock the plethora of threads such as this. It's a pointledly subjective question and a waste of bandwidth.

The answer to this will be different for everybody, dependent on how you use your phone and for what. There is no universal answer. You have to find out what works best for you.
I know that's not a great answer, but it's the honest truth. I, personally, run Jellybro with Franco (on Wheatley), but that's for the mix of features, smoothness, and other factors.

Well just installed it taday. But there was a leak of it and battery was good. I would get about 13 hrs and about 3 1/2 hrs screen time. Im a really heavy user. From 1-10 I give it a 10. I think everybody running this will agree with me.

Just to warn you, I got horrid 3g speeds with fk23...But I think it could be an area thing...
fi27 and f127 modem with agat fi27 v0.6.8 with the rom call lightweight 0.5 its great I get around 9 hrs heavy uses sometimes when I im bored I switch to a backup of jb fk09 tweaked signed I get about 8 hrs heavy uses
Awesome, thanks for the reply! Just wondering, can you define 'heavy'? I personally use my phone at school all the time, I listen to music through headphones about 1/2 of my total day(4 hours or so) and I will also spend a lot of time texting, browsing the web, and using apps that use data. I'm honestly constantly on my phone, and will have to charge it around 3 times per day.

Right now I'm on miui trying it out for the first time getting used to no app drawer. Favorite ROM for a daily (if I had one lols) would have to be Living Rejects. I flash it at least twice a week. Its pretty much my goto when I need a good solid dependable ROM for GPS and coverage while traveling. The battery life is effin amazing and music come out really loud and clear. But I will say once our beloved devs get cm10/AOKP/PA etc running solid for jb I will prolly be going back to PA or try out KK again. I love the UK customization options. I ran ICS aokp as a daily until jb started seeping its way into my veins now I'm flashing like there's no tomorrow can't wait for volume bug fix ^^

[Q] Questions about kernels

I'm new to Android. I made a few posts on here making that abundantly clear (lol). I am just wondering, what exact part of the OS is the kernel? For example, I'm using LiquidSmooth with the default kernel that was included with that. If I were to flash the ktoonsez kernel, what changes would I see? Also, could someone point me to a site where I can download the KT kernel for LiquidSmooth 4.2.1 JellyBean Beta 2? What other kernels are there? What are the advantages of using them? And finally, where can I find them?
I'm looking for a way to conserve battery life right now, but not take away from how my phone currently looks. Sorry for asking such a stupid set of questions, but I'd like to know about this since I plan on sticking with Android. And if that's the case, I wanna learn all about the neat things I can do to make my phone customized, sleek looking, and effective.
Thanks in advance for helping out this new comer to the Android scene
The kernel is the interface between the devices software and hardware. Its basically a bundle of drivers and code to tell the hardware and software how to communicate. All computers use a kernel from windoze to OSux and Linux. Android is based around a modified version of the Linux kernel. You won't see any visual changes when you flash a kernel. And you can find em here in the development or original development sub forums
Sent from my SPH-L900 using Xparent ICS Tapatalk 2
Cool thanks for the detailed explanation. I never really took the time to look up the exact purpose of kernels in an OS but you just explained it to me perfectly.
So, are there any kernels that are better for say battery conservation and performance?
Sent from my SPH-L710 using Tapatalk 2
That all depends on your settings and usage. Theres no one way to get the best battery and performance for your usage, mostly just trial and error trying out different settings and tweaks til you find what works for you. For a good battery performance balance undervolting and overclocking work well. For instance I'm on a note 2 and im overclocked to 1.8ghz and undervolted by 75mv across the board and get almost identical battery to stock, however I still gain in performance without sacrificing battery. Now if I drop my clock rate back to stock and keep the undervolting I get same performance as on stock but my battery life increases by a few hours.

Awesome, installed the KT kernel and used the settings listed in the Kernelizers thread. I also installed DS Battery Saver Pro and now my battery life is amazing. Left my house at 7:05AM this morning and on my way to work over the course of the hour my battery dropped 3%. Usually, my battery would drop 10% - 15% during this time so I am VERY happy with the outcome.
Thanks for all the help guys

Of course. It's just that I know many people have already flashed them all, and I was hoping knowledgeable sources would share their experiences with respect to how they use their phones. Crowd-sourcing, man. Share the knowledge.
Try them all and stop when you find one you like.

Of ones you listed I like AOKP best. Its just clean. IT feels polished.... Deff a possible daily driver if you don't mind bluetooth problems (which might be fixed by now anyway) point is its a good rom. However the one you didn't list in my title is JELLYBAM
Which I use and love. Its not as polished its a mix of 3 sorces... but its dam good.... plus best bat life I have got from a rom Unless you want one thats stripped down (then you can get more bat life) but I like to use my S3 and I enjoy hell out of it... anyway k
Try jellybam.... if its to not the norm for you just go with AOKP or Im sure cm10 be fine too... I never tried them though..
Later bro. There all good in there own way. Try a few its as simple as a back up lol
I've also tried Jellybam for a few days and battery life has surpassed the other roms I've tried (Tasks' AOKP and Liquidsmooth which I've used for about a month each). I mostly use my phone for web browsing, sms, and skype. I do not call much. I was pretty shocked that I was still at 60% after a day (used about 2 hours of screen time). I've also used ktoonsez kernel with the same settings for each rom.

I think tasks Rom is the most supported but I don't use Bluetooth but if you do search the thread about people who do you might find a good Rom. I love aokp and tasks been my daily driver with updates always for about two months I can't go back to touch wiz I tried. Task and I use ktoonz kernel. Either way the built in kernel is fine I just like under clocking and when playing need for speed over clocking is nice to have hope I helped typing on phone sorry for errors.

CM 10.1 is good. I have personally been using LiquidSmooth 3.2.1 beta right now (Android 4.2.1) and it has been very good. Very stable and good battery life, if you keep location based services turned off. On my most conservative usage, this is my best battery life: http://www.twitpic.com/bw26dx
On heavier usage, I can go about 18 hours average and still have about 30 percent or so left.

Thanks for posting.. this thread will soon be closed like the rest with the same question.....
User's mileage may vary on ANY rom. Best thing to do is try one and see how it works for you specifically. Hit the Dev section, find a rom that fits your needs, flash and try it. Great thing about being rooted... Possibilities are endless! Don't like a rom, flash another! Thanks for shopping. Please come again.
