I'm just wondering if there's any known methods to increase the battery life without sacrificing performance. I know the basic stuff like turning off Gps, Wifi, Data, etc. when not needed but is there anything else I can do to prolong the battery life? I'm currently running the wanam lite rom with trininty's alpha 7b kernel. A couple of people reported great battery life with this combo but I'm only getting a little bit better than stock battery life.
What exactly is a little bit better than stock? How many hours are you getting?

Well with moderate use ( 3-4 hours of web browsing, playing games, etc.) on stock I get about 9 hours and with this rom and kernel I get roughly 9 and half.

I get the same too, kind of hate it :/ I don't understand what drain so much when the phone is not in use, I always wonder why stand by time is so bad in my phone, I get much better battery life rooted but I'm stock right now, I got tired of flashing roms and I hate to wipe every time I flashed so I prefer stock to stop doing that

Yeah, The rom is based off of stock H2 and is supposed to have some battery tweaks to make it last longer. All of the people said battery was good using this combo and 1 person said it's been 1 day 16 minutes, and they had 26% left but they didn't post the usage.
Ok this is with the stock rom. Heavy usage by my means any way. It was on the charger for a few mins here and there. But really not enough to show real battery increase.

The best way to determine battery life (not I played a game for a little, surfed the web over 4G, called some, texted all day) is to take a screenshot of your Screen On time, and overall time since charging. Otherwise, your statements are pointless.
If u have a rooted device u should try the highonandriod Rom it dies have better battery life than stock

I'm very happy with Wanam Lite for now, it's so far the smoothest stock rom I've flashed and I'm eagerly awaiting the next update, so I don't really plan on flashing anything else for now. Thanks for the suggestion though, I'll definitely give it a shot when I'm looking for another rom to flash.
Disable auto synchronize. Thats the key.

Don't use the phone. The screen will almost always be your biggest power draw. Screen-on time is relevant because if you have the screen on for three or four hours you aren't going to see battery life that is any better.

Your right, it is relevant when comparing, but I'm not comparing anything here just looking for tips and tricks. I looked at battery stats when I compared the stock battery to the rom battery and recorded both stats on heavy use. If you want statistics, I got 9h 38m of battery use, internet and netflix took up 31% battery consumption, games took up 23%, phone calls and texting took up 12%, and the other 34% is basically screen off time. These were the stats from when I tested it on the Wanam Lite rom. I'm not confused as to why it only lasts about 9 and a half, hours as you can see I was constantly on the phone when I was testing it.

Well not only were you watching a video (I assume, instead of just browsing) Netflix, you were streaming. That probably did a number on your battery. I know I cannot stream Netflix for very long if I want my phone to last through the day. Also games, things that will ramp up the processor, etc while using the screen will tax your battery more than usual.

Some may not like my answer because it removes some bells and whistles, but I suggest turning off all the motion features. Just my two cents. Battery life was better and I found most of the motion features unnecessary.

Yeah, this isn't my everyday use, nor would I do this if I was trying to maximize my battery life. This was purely for testing the battery life on heavy usage and I found that it was only a little bit better when compared to stock. I'm in no way complaining, I think Wanam has done a amazing job with the rom. The stability is great, speed is comparable to JB roms, and battery is a lot better. Unless used heavily as shown above, then it's only slightly better then stock which is kind of odd but makes sense. I was just wondering what all a person could do to maximize their battery life, that's all.

No worries! If you have trouble with idle battery drain, something like Juice Defender will help a lot if you're going to have the phone idle for extended periods of time. Other than that, all I can think of is underclocking (I run at 1350), and sometimes overclocking your min-CPU speed can help as well. The thought behind this is is that the CPU will be able to finish tasks faster, even if slightly, and then be able to go back into deep sleep. I know a lot of people on the Galaxy Nexus forums run 700min, 1000max because of this.

Thanks, I actually didn't know that, I also heard undervolting can increase battery life and reduce the battery/phone heating up but someone said that it can it will have a major effect on the CPU, not sure if it's true or not.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise
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.

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.

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 .
Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
