Hi,
I would like to gather some general thoughts about SK17i's battery life.
I got mine about 8 days ago, everything is good, but the battery life is really disappointing.
In a typical work day I have
- wifi - off
- bluetooth - on during driving, that amount to about 1.5 hours
- mobile network data enabled
- probably 1 hour on phone call, max
- email checked every 30min interval
- browsing - maybe 45min, max
- no task killer software installed
- rooted, build number 368
I unplugged the phone from charger at 7.30am, and now is 6.00pm, 11hours later, the batt is at 20%, about to start giving warning message already.
Is this the typical batt hour you guys get?
one more thing, mine is an Indonesia set so it comes with host of program that I cant use in Malaysia. I have uninstalled most of them, except this MoxierPro which I cant seem to get rid of. I also noticed the program "Games by pop cap" seems to be running actively in the background even though I never start it.
hope to get more input on this.
thanks

yeah its really disappointed but in my mini pro its gave me minimum 24 hours with all time edge+sync+50% brightness. not rooted. stock settings. you know one day i got 4 hours on 100% stats. will upload screenshot soon.
i think u didn't followed up intial instrucitons for battery life like first few days atleast 4 days keep it discharge 100%-4-5% even let it off and then charge again to 0%-100% again dischage same manner, do it atleast 4 times (means 4 days) but before that u need to formate completely and try again. hopes it helps you.
well after coming from x10 mini pro this mini pro really next to awesome. i love it too much. just some boltware apps need to remove. need some games if any have plz tell me.
I think some of the stock app killing the battery, plus the data connection is the most powerful battery drainer. Anyway, first get rooted and remove some of mind blowing stock app. If u can minimize the data connection and use wifi instead of it, that can help improve battery life. My mini pro lasts about 1 day 10hours with minimal data connection but always witb wifi turned on.

on x10, it's been the same. after deleting some crap, the standy time increased from 2 days -> 8 days. especially playnow, trackid, timeshift & facebook including their extensings and plugins are draining the battery a lot.
i suggest to have look in this 2 threads and check, whats "save to remove"

additional there is a very good and simply to setup app you could try:
GREEN POWER - (availible as free and paid version)
http://www.appbrain.com/app/green-power-free-battery-saver/org.gpo.greenpower
Yup I think that some of the stock app is the cause of massive decrease of battery life at night, or during idle. But I just dont know what apps that cause this.
I really want to remove it asap

well i also want to remove, but by unlocking bootloader, i dont want to void the warranty also some features like xperia inside facebook, some camra function also may be stops to work so just waitng if any one root it without unlocking the bootloader. just like xperia x10 mini pro with superone click.
I am trying out Green power, seems to work well as it does not kill app but work from another angle: instead of always on data connection, I set it to turn on every 30 min using green power... so far it looks good.

well when its rooted then try to do a battery calibration
does it also have the BST-38 like the x10 mini pro?
You have to mention that because of the small design you can not expect that they implemented a more awesome battery that is small and has the same capacity like a battery of a large phone like the htc ones. otherwise such a awesome battery would have cost much more and would have made the price much more expensive.
As also the x10 mini pro has a lifetime of about one day I suggest it's the same here
Try turning of G3 and only use G2 if possible. otherwise we should wait until they ported cm7 to the mini pro where you can do this.
Nope, EP500 - 1200mAh, somewhat better talktime is promised in the specifications (5.5 hours) compared to old Mini Pro. But the device is still fresh, some customizations should improve battery life
Is there any high performance EP500 battery on market? like 2000mAh maybe?

Perhaps give time to cycle charge the battery several times (discharge fully, charge fully) so it will run optimal. The bloatware and the apps that keeps running on the background, uninstall them as they seem to be uninstallable. For the Popcap games, only way you can get rid of that is to have root and uninstall it. Since you mentioned you're rooted, take that useless crap out.
My unit is about to get a week old but I have very light usage and looks to me it can last best 3 days, so with normal usage will be definitely less than 2 days, which is like your experience. Anyway, the full cycles I am still trying to do and squeeze out what the EP500 can muster.
This is the best choice I can find on an alternative battery
Code:
http://cgi.ebay.com/130561150352
Looks like has double the capacity, which I believe should at least provide more juice. Planning to buy, but we better see what the fully optimal EP500 can do first.
Also, I'd like to share that I use SetCPU to downclock the CPU when idle to 122.88Mhz. When the phone not rooted, the lowest clock speed is ~245Mhz. In general our phones are more idle/standby than in use, so half the clock speed reduction will be good for the battery. As a sidenote, I wonder why Xperia models are like this (lowest stock clock speeds ~245Mhz), whilst Samsung ones go as low as 100Mhz.

with little to moderate use i can last almost the whole day. with moderate to heavy use forget about it, always bring a charger everywhere i go. i love the compact qwerty phone and speed but the battery is getting to me.

Youre just like me. I just want to root my phone easily using superone click too
Sent from my SK17i using XDA App
I was on the same boat but you just need a bit of confidence. The SuperOneClick even the latest one will not work because the exploit is patched on the stock firmware. That's the reason why bootloader need be unlocked so you can flash the insecure boot.img kernel (opens the exploit), which will enable the SuperOneClick to root the phone.
If you're bothered about the unlock bootloader, that can easily be relocked again following the same process, and you're back to stock.
yes i am trying to understand the rooting process to uninstall apps that is killing the 1200 battery.
you can force stop it but once you use the app again you have to force stop it again, and that can get old quick.

that's the way android works. when you start an app it will remain there unless its programmed to terminate on quit or disable (ie. juicedefender) or have an exit option (ie. opera mobile). they say it has intelligent process management which keeps things in RAM so its instant when you relaunch, and if it needs the memory it will kill useless or sleeping processes.
there's this program "autostarts" (needs root) which you can set to disable apps to start on triggers (ie. after phone startup, or when connectivity state changes), and i use that to ensure that apps that i rarely use but still need in the phone, do not start unless i start them, thereby i save RAM. for instance, i disable TitaniumBackup, because there's no point its running unless i need to backup/restore apps.
I have a disabled data, the 23 hours off wifi, bluetooth every 2 days one hour, the screen brightness to 50%, and the unchecked bravia engine, 12 hours. Generic rom installed, uninstalled all possible programs.
The battery lasts very little.
to see if we can CM7, sure but the battery lasts.
Thank you
First off I want to thank Nitro for Eclipse it is by far the best my phone has run since purchased.
I have noticed tho on .5 that my battery seems to get used up a lot faster. Has anyone else noticed this? I know that Nitro said in his ROM OP that you could change the cpu frequencies in the init.d script. Has this worked for anyone?
If so could you please let me/us know what you did to get better battery usage.
My battery too died really fast when using v5. I adjusted the cpu freq to 216mhz and calibrated the battery. Also tried Overmind's init hack w/ no luck. I have the extended battery and it would need charged after 6 hrs or so. I use my phone a lot but I used to get 11+ hours under similar use..
I recently went back .2.2 where I had better luck w/ battery life. Gonna test this version and hope my battery isn't on its way out.
EDIT: After going back to .2.2 I'm now sitting at 30% with 16+ hrs of similar heavy usage. Nothing against Nitro's v5 but I've had MUCH better battery life on .2.2 Never gave much thought to the reboot "fix".

How do you change frequencies? I was trying to change governors but it wouldn't let me
Sent from my DROID X2 using XDA App
The only way I was able to change governers is using the Droid overclock app and installing busybox OR flashing a init.d hack. Not really sure how the app opened up the governors for me, but I know for a fact that init d hack works.

So there is no real fix as of yet. I am not going to reboot my phone after each charge, that is obviously a band aid fix and I actually like to see how long my phone runs (well) without needing a reboot.
I really like 0.5 so I'd rather not go back to 0.2.2 just for the better battery usage.
It cannot be a kernel issue because since GB was released the Kernel never changed and it hasn't been since I flashed Eclipse 0.5 that my battery life has decreased.
It must be something to do with the ROM, I am sure it will be straightened out soon. One of the genius script writers will provide a hack or there will be settings tweak that helps. Until then it is not nearly a deal breaker, I can still use my phone like normal. It is just something I happened to notice now that we have 1% battery level increments. 5% in my case, I'm running TheMuffStuff's Cyan Ice Cream Blur.
I'm Pretty Sure The Kernel Did Change, Kinda The Big Topic With 2nd-init.

Sorry I don't mean to be rude or ignore the fact that rebooting fixes the battery usage just feel it is more of a band aid than a fix.
Mikey, I apologize I didn't realize that the kernel was able to be modified with a locked boot loader. I do realize that 2nd init hijacks certain process within the kernel and allows for modifications I just didn't know that the actual kernel we were running in eclipse .5 differed from the stock GB kernel.
I will be the first to admit that I have a lot to learn when it comes to the Android OS. I am very thankful to those with the knowledge to bring out these phones full potential.
Just Wanna Be Clear I Was Referring That Gingerbread Kernel Is Different From Froyo.
Not Stock Gingerbread To Eclipse Rom.
I Could Be Wrong And That's Fine, Wanted To Be Clear If I'm Wrong.
I never noticed the battery problem 'cause I'm used to rebooting my phone every morning anyway (coming from a long time windows mobile user) that stupid piece of crap got me in that habit, but this phone is fast as all get out. you can hit reboot, go take your morning whiz and it'll be back up and running before you even start peein!
it's like the playstation 3 of smartphones, just be patient and wait for the software to catch up with the hardware.
maybe adjust your usage a little too. turn off all your stupid data-hungry apps. the 3g radio in this thing sucks juice like nobody's business. but you can play games/music/movies all day long in airplane mode.
I've already gotten 7 solid hours of playin music + stupid zombies while traveling. I'll turn my radio on only when I want to be bothered.
it surprises me that even the wifi doesn't kill it like the 3g radio does. if I'm on wifi all day long my battery life is AWESOME. I've even taken out the 3g tweaks from my eclipse.5 and now I have no trouble getting 12+ hours between charges. the absolute worst thing for the battery is music + wifi tether (I like using the phone hooked to my speakers for general music listening 'cause I don't miss any notifications)
the fact of the matter is, these phones will never have good battery life until the radio gets a serious update/overhaul. it seems like it transmits at FULL power constantly even if it's not necessary.
you want battery savings? turn off background data and put it in max batt saver mode. it doesn't make things that much slower and as soon as you wake the phone it reconnects pretty quickly and updates whatever you were missing out on. that and honestly, it's nice to not be notified about every piece of junkmail that reaches my inbox on a daily basis. people can text you just as easily as e-mail, and if they can't respect that, they don't deserve your respect in return.
who even had a cellphone 15 years ago, let alone all this other crap that comes along with "smart" phones. we all got along fine without them before.
come to think of it, I have never had issues with music skipping either, but I don't let my phone frivolously piss away data either. something to think about, but I remember the days when I paid by the MEGABYTE for data service too.

Dunno how others feel but I liked this post.
I recommend juice defender I love to set it to turn off all data while the screen is off. And I set it to turn it on every two hours for a minute to retrieve gmail and such. Has helped save so much battery lately and works great. That way I don't have to mess around with going g into settings to turn off data and on every time I wanna check. I also leave it in my notification bar so I can just pull down and tap and it cuts my data. Also have seen I can set it to turn off and on data when using any app I just haven't configured that setting yet. I have noticed up to 4hrs more battery when I have juice defender enabled .
I agree completely on the radio. Even when I have a very very good signal if im not using wifi and pulling data from 3g my battery has been almost completely drained within a few hours of heavy use just browsing the web. Its crazy how much juice it sucks down.

I will definitely check out juice defender. I am by no means complaining about the battery usage at all. My phone still lasts all day with the same amount of use I have always had.
I had just noticed a difference going from Eclipse .2 to .5, and it was even mentioned by Nitro that people may experience a higher battery usage with this rom. I was simply wondering if anyone had applied a script or modified a setting (as stated in OP) that made a difference. I tried to change the cpu values in the script but it didn't make a difference for me. If anyone did make a change please post the change you made and how you made it.
Sounds like rebooting after charging, or using software to modify data usage is what works the best for now.
I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:

Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
Hi all,
first of all, I'm not a fan boy of any kind. I've been using so many android devices in the last years, I'm more of a tech fanboy then a <brand>fanboy.
Given that, I'm not soddisfied at all with S3: reading and viewing so many preview and review of this phone, I though it will last more than one day and that it would be fast as hell and lag free, at least, this is what everyone is saying in every damned review I saw/read.
I had in these passed 6 month: gaalxy s2, sensation, galaxy note, sensation xe, galacy nexus and right now htc one x and sgs3.
Well, the sgs3 is not so much better as everyone is saying, in particular, is not better at all of htc one x as every comparison review is stating.
What's up? Is that just me or what? My sgs3, with the same operator's sim is lasting less than htc one x and it's not fluid at all, at least while scrolling through homes!!! Of course, even the one x has some microlagging while scrolling through homes, but I though sgs3 would have no lag at all.
Does anyone else see it?
What it's really strange dealing with battery drain, is that the phone drains a lot even while in standby. The first voice in my battery stats is phone cellular stanby? How can it drain more than the screen???
Any "smart" answer is very appreciated, but please, avoid phrases like "you got a lemon, change it": what I'm saying it's not that it lasts me4 hours, I can get through the whole day with sgs3. But it does not last more than one day as everyone is stating! I mean: I get 17h unplugged with 3h screen on, it's on par with all the other phones I had...but not with Galaxy note or One X, they really last more than one day.
Thanks
Can you make a video of the lag so that we can see what you're experiencing? because I and most people have a smooth interface so maybe an app or your setup is causing problems?
Regarding the battery life, I got something like 22 hours with 5 hours screen-on (screenshot in battery life thread in general) and that was with pretty heavy usage - games, videos, web browsing. But you're right there's definitely high cell standby drain in the current firmware. Hopefully it can be fixed. Also, there's an led notification app, can't remember what it's called, that has a bug that drains the battery on the gs3. See the battery life thread in general for more info.

Hi, first of all, thanks for your answer. I'm not talking about huge lag, but the tipical microlag that you get while scrolling through homes in every android phone up to nowdays. I got some microlag while scrolling on HTC One X too.
If I can I will upload something tonite.
Your battery stats is great: 22h with 5h screen-on is a very good result. Do you use data connection always on? How many charge cycle did you perform?
Anyway, no, I'm not using light flow as my phone is still on stock rom, no mod yet!
TIA
Yeh wifi and 3g always on. here's a link: http://forum.xda-developers.com/showthread.php?p=26864539#post26864539
But even with the good results I'm getting, I don't think the phone would last 2 days because of the high cell standby drain. Its definitely a problem that needs to be fixed.
Regarding the lag. I get UI framerate drops in the following:
- Task switcher if there are a lot of apps open
- Browser bookmarks with thumbnails enabled
But they're the only areas that I've noticed have noticeable fps drops. Another annoying thing is for example the ABCDEF... list to the right of the contacts list, it seems to take a second or so to become responsive when you start dragging your finger down it, kinda spoils the experience.
Also, touchwiz launcher seems to need to reload when RAM gets used up.
So yeh it's not perfect but overall it's lightning fast and battery life is superb. Will be even better with software updates
I'm getting 1day 5 hours with 7 hours screen on and minimal standby drain.
The only lag I experience is 'sticky' vertical scrolling.
I did drop touchwiz in favor of go launcher but that was only because I found it too boring.
So far this phone has more than lived up to my expectations.

Do you mean you have no lag at all (neither a micro lag) when scrolling through homes?
Yes, noticed the launcher reload sometimes.
I don't know, maybe it's just me 'cause I had so many phones and in particular an HTC One X to compare it with? I don't find it any faster than one x but in web browser, nor it lasts more than one x! :/

No noticeable fps drops when swiping through the home screens no. I only have widgets on 4 pages though so will try adding more and see if that makes a difference.
I also owned a hox (tegra3) but returned it because of the bad battery life and laggy browsing (tried lots of 3rd party browsers too) and ui fps drops, overheating and screen flex.
I had a hd2 and had managed to get pretty good battery life on it as well.
I find a lot of little things add up.
I let very few apps sync.
I have black or dark backgrounds wherever possible.
I don't use haptic feedback.
I only use gsm unless I'm actually doing something that requires more speed but I do have data always on.
I switch WiFi and GPS off when not in use.
I use auto brightness.
I use betterbatterystats and battery monitor pro to keep an eye on things.
I avoid battery savings apps like the plague as they invariably increase battery drain.
Hope some of these help.

That's funny, I have a tegra 3 One X and I have none of the problem you had, or, at least:
- first one x rom was quite laggy, now it's much better, on par with s3, but always with some microlag
- no overheat but when playing heavy games like shadowgun, while s3 gets really hot even when just surfing
- very decent battery life, better than s3
- no screen flex
- no laggy browser until flash player is on demand
Oh well, maybe my One X is an S3 and the S3 is a One X!?!?
Joking apart, you can notice microlag when you scroll very fast through homes both on One X and on S3. I have 5 pages and widget on every page on both phones.

I have several app syncing (4 gmail account, 1 yahoo account and 1 exchange account, everyone along with its calendar part), twitter every 30 min, beautiful widget weather every 1h. GPS always on, 3g data always on. Auto brightness on all the time.
I see, using gsm only, no gps and few apps syncing really extend battery life, but I want to be able to fully use my phone. Moreover, both One X and S3 have the same apps, the same account synced and almost the same widgets (sense one apart), but One X last longer!

Anyway I placed widgets on all 7 pages and swiped really fast and have no lag or fps drops whatsoever. Maybe a particular widget is causing the problem?
I found using the live wallpapers caused my home screen to reload and caused lag. Since changing to a static wallpaper everything has been nice and quick with no re-drawing

Of course, I've already tried everything I could in order to lessen the lag: I'm using a static wallpaper, but micro lag is there. Maybe it's ust a matter of defying what microlag is: if I do scroll fast through home pages I have some microlag, I can see the animation is not completely fluid.
I have the following widgets: beautiful widget clock 4x1 (but I tried even with samsung standard plain digital clock), google search widget, music widget, stock ics calendar widget, plume (but I even tried with the static official twitter widget), photo gallery widget, weather pro widget.

One more thing: using SpyCPU I saw that sgs3 it's for 70% of its total standby time in deep sleep, while one x it's for 80%. Moreover, one x has more states with low CPU freq (100mhz, 70, 50) while sgs3 has 400mhz as lower freq used state, 300 and 200 are unused. :/
I guess that the Tegra companion core going so low in frequencies...
hey, so i have ran pretty much every "jelly bean" rom out there for this phone for about 2-2.5 months. maybe less. note sure..
anyway, the battery has been horrible! on every rom.. I have a 2700 mAMP battery, and a regular Samsung battery. I have to use both once a day for this phone.. now I have no idea what is making the phone loose percentage after percentage of battery as fast as it has for me, but everytime i post i get about 0 luck from people that either have the same issue, or just people saying they have heard it a million times. i probably should have put this in the "Q&A" thread, but maybe i forgot. can someone, preferably more than one, help me out here?? i don't get how other people say they have 8 or more hours of screen on time with half the battery left. it just doesn't make since. I am loving the android system. but this could be anything! the apps in the background. the kernel, maybe I didn't clean my cache or something. i can't raise my brightness up to far or it'll drain my battery, jamie in the paranoid thread said he had his batter on 100 percent and had excellent battery. so I'm far from confused here. do I need to get another phone, or what. very much apprentice the help from as many people as possible. I love my phone, but I hate that i have to focus on using two battery a day with this phone.
Same here battery draining pretty quick on all jb ROMs.

Battery usage is highly subjective..
It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.
We know the obvious power users ....the display, wifi, data ..
But it gets far more difficult to track the Usage after that.
We know that JB is not optimized for our device, but it's getting better, and until we see a true JB kernel with the rom matched to it, the battery is going to suffer.
Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g
to get better battery turn brightness to lowest usable setting, turn off sync for any non essential apps, turn off soft key lights, flash a kernel that lets you under volt and under clock, try different govonors and io schedulers, turn off gps, put in airplane mode when not using. these should help. keep in mind cell signal strength will also impact battery and 4g will kill it faster then 3g. i am on cm9 stable under clocked to 1.18 undervolt all by 25mv( not much change but i like to be safe) ondemand and sio and get amazing battery life.
What's your screen-on time? 4 hours is the close to the limit on ANY rom for our Notes. You have to make sure it's not some sort of confirmation bias going on here.

thank you so much man! i actually went to at&t and they mentioned that too. they said the kernel im using isn't fully optimized for the phone yet. other words. the phone wont support it. he said basic stock ics is the best thing to do now. he also said. these forums are for phones from Europe as well. not just for AT&T in the us. again, the ROMS these devs are making are not supported for the phone, and is kinda like a mimic of something its not. he said jelly bean was out, but i don't know where to get it. can someone tell me how to install ICS, because when I download it, and use KIES, it installs the system, but never fully completes the process.

Sure...
At the top of the general note section, you will find the "note super everything thread"....
Scroll down to find the ICS info you need...
There are many great ICS roms, and you will find that your phone is "MUCH" better running on the software that was intended for it..
Do the homework in the superthread, and read, read, read......then if you have more questions....just PM me, and we'll get ya up and running....g

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

I was not aware of this info....many thanks for the heads up...I always supposed that since the ram was consumed with applications, that those apps were pulling CPU usage from the device...
that is clearly not the case......g
Yep, no problem. If you go back to a touchwiz based ROM and go into the stock task manager, it shows you what's taking up RAM, as well as the CPU usage of each thing in the list. If the apps are working properly, pretty much everything will show very little to 0% CPU usage, and ones that are using it heavily will even be highlighted in yellow or red depending on their CPU usage %age. Unfortunately aosp based ROMs don't have that task manager, one of the things I miss from touchwiz.
Every time a non-techy friend buys a new android, it seems the overly aggressive sales rep that sold the phone to them 'helped' them get to know the phone and installed a task killer, specifically advanced task killer. I always just uninstall it without telling them and see how long it takes them to notice lol.
It's still useful in certain instances, for example if you have an app that doesn't run well but you still like/need to use, but in general practice android does a much better job of managing itself. Besides, if you have an app that you know runs poorly and hogs your processor in the background, but you still need to use it, with most aosp based ROMs you can set your phone so that long pressing the back button kills the current app, essentially making task killers useless.

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

That's a very big heads up. Thanks. But thing is when I have wifi on. Don't I need to be connected to wifi network first before it actually can help me??

This is true. What kind of signal strength do you get where you are at? Does your phone bounce back and forth to lte. I have noticed when i go from a strong signal to weaker signals or band switching a lot, my battery drains rapidly.
Use cpuspy, as mentioned, to verify you do see deep sleep. Also, i find if rooted, that seting the min speed to 192 helps quite a bit.
