Let me start off with the good in this rant. This device is BEAUTIFUL and has A LOT of potential. Considering i just rooted it, it is even more fantastic BUT (there is always a "but" in life) here are my issues that i PRAY would go away. For some odd reason, though i have done everything i can to prevent it from happening, the battery life is just terrible! And here is the mind blowing part: My brightness is always at about 15-30 percent, my automatic sleep is at 15 seconds, i am never on 4G, NFC is off and my GPS is almost, always off. I recently learned that having a lot of black (Wallpaper, themes or simply a black display) going on prevents the display from eating up battery, therefore i've blackened what i use most (MMS, Gmail, Instagram and of course a black wallpaper) but after all of that, the battery still tends to suck major ball sack (sorry for the vivid image). If you must know i am using an AOKP rom, Jelly bean. I absolutely love the rom.
On behalf of that rant ^ .. Is there anything anyone could/would suggest i do in order to have a better experience with battery? Maybe a different rom that revolves around better battery life? Anything that i am missing to prevent battery from draining so fast? AM I THE ONLY ONE GOING THROUGH THIS?!
Last but not least, what gets me going and makes me want to punch something is the fact that my phone constantly, CONSTANTLY heats up for NO REASON (i'm assuming theres an actual reason but i have no idea what it is). After a full charge, i'd unplug the device and couple mins in after browsing web for like 60 seconds and texting, it'd start burning on the top of the screen and the back where the camera is. What is that all about?
And on behalf of that second rant ^ .. is there a solution for that? AM I THE ONLY ONE GOING THROUGH THIS?! lol

Check out what my battery looked like after a few mins from unplugging it. Screen, 67% ??????
Believe it or not... I had a battery go bad already on me. Now i was short charging it and stuff like that.. but still. The early builds weren't as efficient as this one is. You might try a new battery. Or the oem extended one. I have had good luck with both routes. Oh, and i'm stock.
Lots of battery drain and a hot phone means that it's trying to do something. Looking at your screenshot, you're not having any signal problems, which would lead me to believe it's a rogue app. What was your total screen on time during that 48 minutes?

i honestly don't remember, i THINK it was probably 32 mins because thats what i see every time i see the battery that way. If that makes any sense.
Which kernel are you running with that rom? I had a JellyBean rom with a kernel that increased overall, but my phone would often heat up and battery life was not the best. Changed roms and kernel and everything is cool now.

32 minutes of screen on being 29% of your battery. That makes roughly 110 minutes of screen on for the entire battery. Running a stock battery? I never did, but I think people have said 2 hours screen on is the low end for a normal battery. I could be wrong, though.

2 hrs is the low end for OEM battery? I'm lucky to get over an hour and a half on OEM extended. GNex battery is unbelievably horrid.

Or the high end. I got mine as a replacement device for the Droid Charge, so I had to order a battery and back cover when they offered it to me. Since VZW had a 50% off sale on the 2100mAh battery and back, I went with that. So I've literally never used the standard OEM battery with the phone.
Try going to this link: http://minooch.com/franciscofranco/Galaxy Nexus/JB/Jelly Bean/
and downloading "franco.Kernel-r225-384GPU.zip" flash it in recovery like you would a normal rom. Franco's kernel is extremely stable and works magic for good battery life. Should also resolve your overheating issue. If not, I'd suggest a full wipe and installing a different rom.

Terrific! So no need for a data/cache wipe? I can flash this over the current ROM I'm using? Backup I'll do of course but yeah.

I normally wipe cache, not sure if it's required. But yeah, it's not a new rom or anything, just different kernel to test out and see if the kernel is what was causing your battery issues.
I'm using the jbsorcery beta with the lean kernel and under clocked with the modded voltage and this is heavy usage on Facebook and texting and about 30 min on the phone I have about 2hrs 45min and im at 80%

Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.
If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.
I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%
Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB
I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.
EDIT: I just installed GSam. Thanks for the tip!

Maybe you should've posted this after receiving and using your new battery. My phone had horrible battery life after a while on ICS but it turned out that it was in fact the battery and not ICS. Got a new battery and it is back to 18 hours a day (on ICS)

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...
https://play.google.com/store/apps/...av_result#?t=W251bGwsMSwxLDMsImNjYzcxLmJtdyJd
Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
So I bought my ATT GS3 out in Los Angeles this summer and then I returned to New Jersey to find that I have horrible battery life. It was not right away so this could be completely unrelated. As of right now my phone is at 75% and I let it drain while i was sleeping for 10.5 hours. I have tried several different roms which are usually good the first two days and then after that the battery life is bad again. I thought it may be some application I have installed so I removed a few of the ones I remembered downloading since I got back to NJ. I also updated to the latest radio ending in H9 because I was two behind when I checked. I have attached some battery information below. Any help anyone could provide would be great. I have tried Juice Defender which did save some battery life but it also caused a problem where I couldn't use the internet for 10 seconds after I wake the phone.

I thought the cell standby problem only effected the international GS3? If the cell standby fix was the problem then I shouldn't actually be draining that low right? Something must be draining the battery then. Google maps is probably draining the battery but how do I stop that from happening?

Just another observation. Battery tends to drain faster if you leave it in your pocket. If you flash a rom, you might have to calibrate the battery stats. I only lose 1% every 2 hours overnight if I leave it on a cold surface.

So I have tried a few different roms and I'm still not happy with the battery life. I calibrate the battery after every rom installed and I usually keep that rom for atleast 2 days to test it. Right now I'm on AOKP. If the phone is on standby whats the general %/hr? When I go to sleep my phone drops from 92%-75% for about 10-11 hours (on desk at temp 60F). By Apocalypse487's response I should only see a drop of 5-6 % over night when I see 17%. Am I supposed to me losing this much battery life over night? To me I feel like I barely use my phone. Today wasn't too bad with 1 hr with screen on and about 1 hr in calls. I made it about 1 day 1 hour 36min on battery. My phone was sleeping for about 23.5 hours. Is this the typical battery life or is something wrong with mine? Tonight I'm going to try juicedefender and see if that helps.

I'm using ParanoidAndroid based off of CM10. Version 2.16 of PA gave me the best battery life. Try that. Certain Roms have better battery management, but that probably depends on the kernel. PA uses stock.
Sent from my SAMSUNG-SGH-I747 using xda premium
I'll give ParanoidAndroid a try and see what that does. So Juicedefender ended up making it so I only lost 1% over 9 hours. Thats pretty good. Way better than I wanted. So what could be draining the power over night. Is it because my data is on all the time but shut off when using Juicedefender?
I use Trinue 2, and I use an app called Go Power Master.
In GPM you can setup options that will turn off mobile data/gps/wifi when the screen is turned off, will automatically turn them back on when the screen is back on.
Those things little things I find can make a big difference for the battery to last throughout the day.

It's as Sianspheric says, common things like gps, data, and wifi uses power. I just started using Juicedefender since my friend told me it helps. Also download battery calibration. It's a root only app. Don't let your device discharge completely. It's bad for Lithium Ion batteries. That will clear out any bad data from Samsung.

What's up with these threads in the wrong places every so often? It's like no one reads the rules now-a-days...
And also, don't just say that your battery life is bad without giving members a time of how long the battery lasts. We don't want to guess how long your battery lasts.

I would say in between ... my biggest question was really about the kernels. I can determine for myself what is good battery life with experimenting with flashing different kernels, among other things. I'm just looking for a bit more information on flashing a kernel, ones I can, ones I can't, etc.

Same here. I cannot get my phone past the 5 hour mark if I am using it. If I just leave it next to me alone, it lasts 7. If I have wifi on, however, it lasts 15! My guess is how strong the network is and whether or not you have an exchange account synced affects it. Another thing is, after a full charge your phone running CM10 will refuse to enter deep sleep for some reason, making for some very disappointing battery life. Rebooting it every time you disconnect a charger helps somewhat, but that's hardly practical: with a battery life this bad, that makes rebooting every hour since I keep it plugged in everywhere I can. I am resigned to lugging an external battery everywhere I go and hate every minute of it.
As for another kernel, don't bother. Battery life has sucked for me with every last rom and kernel combo I have tried, including stock. Numbers have been pretty much the same, and there are no wakelocks on it. What another kernel did manage to do is make my phone really hot and really slow, as well as reboot whenever it feels like it. Phone becomes utterly unusable.
Kernel won't help you. You are not solving one problem, you are solving several : radio, deep sleep and demand for data.

By the way, I was referring to the current crop of custom kernels for CM10. I wrote it as a general statement and I didn't mean it to be.
There used to be one kernel called KKO. If it gets ported to CM10, get it. Your battery life will still suck, but you will have a slightly snappier phone and more governors to play with. You can squeeze maybe an extra half-hour from the phone this way. Insignificant, I know. Also, the extended batteries are all sacrificing something: either NFC functionality, or the slimness of your phone (some require a custom back cover), or both. In the end, when you do the math, it adds about 2 hours of runtime to your phone: you are still running from charger to charger. The external battery gives me an additional ~7 hours of heavy use, but is a big phone-sized object tethered to my phone with a USB cable. I look like a suicide bomber with a wire running between my pockets. Not ideal, not by a long shot.
I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced
Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.
You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I didnt really notice any improvements on the KT747 vs stock kernel.
I greenify everything except for the messaging apps. But then again, when my screen is on, i want ot be using those apps.

KT747
3G good signal.
Using tune in radio while texting on go sms and surfing using chrome with 7 tabs open

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.
Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I tried customs like AOKP, PA, CM etc before. I dindt notice a gain in bat life.
I do enjoy's stocks stability so I would like to find a solution with my stock phone. But doesnt see like theres one....

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .
