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.

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.

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%

So I've come to accept that the Incredibles battery life is terrible. But after rooting and flashing new ROMs, how come my battery life is even MORE terrible?? Is it because I've downloaded too many apps? My phone was just charged to full and as I post this it already dropped 10%. I can't get my battery life past 6hours of moderate use ie texting and occasional browsing. This can't be normal, or is it??

Good explanation on what happens to your battery when you think it's being fully charged.
Concerning ROMs that boost battery life, have you looked into those that are basically just tweaked, scaled-down versions of stock ROMs? I'm running Magnolia 1.3.1 and getting more than a day of use with a good amount of texting, calling, browsing, apps, etc.
And this is on the stock kernel! My Dinc is running so well I don't want to screw anything up by flashing a different one haha
Another suggestion would be to use setcpu or similar app to underclock slightly at all times, and drastically on screen off...these processors are plenty fast, and you may not even notice 100-300 hertz less through the day.

My battery came as a lemon, so I got a new one under warranty and battery life quadrupled. My battery life was insanely bad (like 3 or 4 hours light/medium use) so if yours is that bad your battery might be bad too.

My battery life was much worse with the stock ROM.
I am using the CM7 nightly, my battery life is much better using this rom opposed to the stock.
One thing I had to do was to turn off auto brightness and manually set the brightness. I usually set it to about 1/4 or 1/3 of the way up as the screen is bright enough for indoor use.
I watch a lot of videos and this comsumes battery, but with the brightness manually adjusted it was much better. ex if a normal video used 20% of the battery for a 22 minute show, it now uses about 10 to 13%.
Also I noticed that when I am at 100% charge, it drops to 93% in about 10-20 minutes. After that it stablizes and appears to give a more accurate reading.
those are my suggestions. I have had the same results with all the CM roms.
Latest CM7 nightly gave my wife's phone 1 day 11 hours to get down to 20% charge, with typical (for her) usage. Meaning a lot of touchdown email checking/facebook stuff, not a lot of talking.
Well, once upon (a greater) time for my phone, the battery life was phenomenal. I would take it off the charger at 6AM, and with moderate use, still be at about 50% when I got home at around 8PM. Now, I can't even have the phone off of the charger for a few hours, because "Android OS" eats my battery. I went from 100-60 in like 3 hours off of the charger with the screen OFF.
I've had various CM9 and CM10 installs, and it seems like they're what started the bad battery life. I used Mobile ODIN to flash back to EL29, and flashed the EL29 modem .zip in CWM, and the battery life is STILL ****ty. What do you think it could be?

Swollen battery is ALWAYS a bad battery. They swell when a cell begins to or has ruptured inside the housing and can do some serious damage if the housing bursts. At temps above 130 with a swollen battery the chance of a full housing breach goes up 70% at 160 its almost guaranteed to breach and at 180-190 it will burst causing somewhat of an explosion. Exposed batteries not sandwhiched inside a device actually produce a pretty large fireball when the burst at those temps and the housing does enough damage it could be fatal. I've burst quite a few using a hotplate and sitting the battery on it inside an acrylic aquarium and letting it heat til failure. If your battery is swollen stop use immediately and get it replaced. You can end up with serious injuries and if it bursts while you're talking on it possible death and at the minimum severe chemical and/or thermal burns :thumbdown: not fun

I am so incredibly happy! I haven't had time to go through all the info in the links you posted, but instead took the cheap and easy way out and simply froze Google Maps using Titanium Backup. My battery life was awesome today!!!! It could still use improvement, but I finally feel like I'm making significant progress. Yes, I'll go through the posts you linked more thoroughly when I have time and I'll work on disabling maps in startup, but for now, I can feel confident that my battery will last all day. Whew!
So, no matter what I do my battery life stays the same regardless of what rom or kernel I'm running. So now I'm wondering if it's my battery, but I'm thinking even if my battery was bad the rom or kernel should have some sort of effect on battery life. Does anyone know if this may be the cause of a bad battery or what else could be the issue, I know for sure it's not the rom or kernel so it has to either be a problem with my phone or battery but I'm not sure which one it is.
Try running a looped video run down test. And report what you get for screen on time.

Yeah, that seems very low, I guess you may have a bad battery, by the way what ROM were you running when you did that test and you did test it from a full charge right?
Yeah I tested from 100%, I'm running Frosty JB v3.0, It's insanely smooth but like the other roms it wasn't able to increase my battery life. So far the only thing that will increase battery life is if I underclock the cpu. Other than that nothing else I've tried works.

I honestly don't think your battery life is that terrible. Streaming Netflix destroys your battery regardless of wifi or mobile data, and so does playing a game. Three hours of screen on time isn't that bad, especially considering you watched netflix for two hours and in your screenshot you have no bars of signal, which will also destroy your battery in a hurry.

There are no bars because I turned off data and was using wifi, I agree that netflix drains more than an average video played off the phone but I still think this is horrible. I mean 5 hours total is not something to brag about when your screen on time was only 3 hours, not to mention I underclocked to 1.2ghz to save power and was on the lowest brightness setting.

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.

Its in my sig

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