Your screen brightness is too high and turn off haptic feedback. Btw screen love to rape your battery

I think its the FC22 modem. Obviously modems vary from phone to phone. Flashed it over Calk GB ROM and my battery life TANKED. Went to sleep with 30%, woke up with 4%, nothing in use either

Debloat out the samsung widgets and sprintware you don't used. Makes a huge difference. Check with John C for other battery saving tips.

thanks guys I just saw Calk released fc 24 Maybe that will help with the battery life?? cuz is ridiculous right now.

Are you using auto screen brightness? It is usually enabled by default. If so turn that off and set you screen manually. Personally I hardly ever need more the 25% brightness level.
Another tip, pick up Better Battery Stats on the android market for $2.50. You will be able to see right away your awake time vs your screen on. That way you can see if a rogue app is killing your battery life.

I hope you guys meaning "good battery life for an ICS build."
I'm still running Calk's EL29, and when I see people saying 40% use over 5 hours is great battery life, I feel like I'm in some Bizzarro world!
With medium use at 50% brightness (2 hours of screen-on, 50 texts or so, WiFi and GPS not disabled, 20 minutes or so of actual phone time), I find myself somewhere between 20 and 25% depleted.
Granted, my screen on time is mostly dark things... White on black Kindle reading, white on black text theme, dark background pic, etc).

Using my old HTC EVO for the weekend and I forgot how amazing it was for idle battery drain, must be due better more mature custom kernel.
Bad side though is I don't remember it being so fat and heavy! got spoiled by how slim and light the gs2 is.

WTF 15hrs thats crazy,.. im running this same ROM too but nowhere near that bat life it has improved a lot but unlike this..

um.. web browsing uses 2 of the biggest battery drains of any smartphone, the screen and the 3g/4g radio. there isn't much you can do to minimize battery drain during activities that utilize one let alone both of them.. even surfing on wifi is going to make your phone drain a lot faster

dam my android os is eating my battery and I cant figure how?

okcupid I didn't know what it was till I Googled it. good luck

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?

Sent from my SGH-T989 using XDA

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.

unfourtunately im seeing no results. i got about 6-7 hours still on decent amount of usage. i even went ahead and purchased the extended battery from nexus and im still seeing no improvements! im pretty sure its not a rogue app because i barely use any apps. im even using apps like 2x battery to try to get more juice. anyways i just wiped and installed digital warfare last night. just unplugged my phone at 100% lets see how this goes. ill report back.

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.

[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.

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.

Extended battery dying quickly

If you look at the screen shot, my 4300 MAH battery was dying with only gps on on low brightness screen time of 2 hours and 30 min. This is very short compared to a week ago when I got it, I got almost 6 hours of screen time.
Also I had about 45 min of screen time with juicedefender on and then idle from 7 to 1:47 today and 73% battery!?
Remember this is an extended battery, this seems too quick.
Could it be the battery, or programs on my phone. But I checked battery and screen was the most battery consumption on Low brightness. And nothing running in the backround

Well, the only stable is cm10 stable, which is android 4.1.2, not 4.2.2.. but I personally love cm10 stable. You could try to dirty flash, but I have never went down an android level over dirty flash, but I would imagine it would not end well. I would recommend a clean flash. If you need a good backup app, look into app backup and restore for your apps and mybackup for text and app data. It can backup so much and is so simple to use. Both in play store.
Sorry about having to clean flash, but after you do, if it isn't your battery (which I believe it isn't), battery life should be improved greatly.

I know people will argue otherwise, but the only thing different I see in 4.2.2 is 4 things.
the camera, which I flashed on 4.1.2 because I found a zip. Loving it.
4.2 keyboard, which I also have on 4.1.2. Very cool.
The lock screen which personally I think it is a good idea but it isn't that important to me. Cm10 stable is better suited because it is simple.
And last which is the quick toggles. I like this feature too but isn't a deal breaker for me. As cool as they are, I just use the power widgets in cm10 stable and they work just fine.
I know they say 4.2.2 helps improve battery life, and yes, in the long run it will. I don't know what nightly you flashed, but they are exactly what they are, nightly. They are just test for new things they put in to see if anything breaks. I am personally gonna wait till I see a stable 4.2.2. Rom until I make the jump up. 4.2.2. Is gonna have bugs as it is brand new. I can wait until the bugs are squished. If you want awesome battery life, you could try some of these touchwiz ROMs. Sometimes AOSP doesn't play nice with some phones as every phone is different.
So do as you wish. If you can live without some 4.2 features (which some you can get on 4.1.2) then make the jump. If the battery still acts up on 4.2 to where it bothers you, then switch. If you don't mind it stay. It is all up to you. .
I also forgot to add: if you flashed a nightly of cm 10.1, you could try the snapshot (monthly build by cm people).
These are considered more stable for daily use.
I am gonna go to bed now, but if you have anymore questions, feel free to ask/pm me. I will get to answering them as soon as possible.
Hope it all works out.

I had the worst luck with most aftermarket batteries, tried all brands, from everywhere, some didn't bother about telling you there is no NFC chip, and, they all got super hot while charging. None of them seemed to hold a charge longer than OEM.

[Q] Battery life ROM

Hey All,
I flashed the Shiny ROM recently. I am getting pretty bad battery life though I didn't own the phone long enough before flashing a Shiny to know if this was a Shiny issue or not. Anyways, I like the ROM well enough but was curious if anyone could suggest another ROM that perhaps goes easier on the battery. I am just on the edge of getting a zero lemon battery but thought I might try a few more software tricks before I plunk down the cash for that battery.
I have already replaced the shiny kernel that is baked into the ROM with the KK422 kernel which I had heard is easy on the battery. Seems to be helping a bit so far.
I know that battery use is highly individual, I am mostly looking for a starting suggestion. I can run my own usage diagnostics.
Thanks yet again!

Use greenify and wakelockdetector. Also you can try to tweak with trickster to get better battery.

Thanks. After I wrote that OP it occurred to me, probably kernels more so than ROMs affect battery life. Just based on the little that I now that would seem to be the case. Is that true at all?

Yeah I noticed better battery life with kernels not so much by switching roms..
