Battery life is something that definitely concerns everyone.
Lately we've been seeing a considerable increase in the number of tips, tweaks, and some apps to improve battery life in our nexus phones.
New modded kernels are also starting to pop up since kmobs released his UV one, followed by psyq's and insectRaven's, among others. I've even read comments about having 70% battery power after about 15 hours of use with AVS! Damn, what's your secret you people?
As well as undervolting, AVS, and other kernel-based configs, people are also starting to talk about how each ROM optimizes battery use. Some claim Emmother has better results than CM. Some are just fine with CM.
There have also been several comments about slow charging being better than fast 1A charging.
So, to join all these things together, I've created this post to see how much battery are YOU getting and what's your setup. Hopefully, we can all benefit from the information that's collected here once it gets going.
Please post in a clear and organized manner so we can all get some useful info out of this thread. I encourage you to follow this way of posting your info:
ROM: Whatever ROM you're using.
Kernel: Whatever kernel you're using (please be specific about extra features it may include)
System & software related:Widgets: Any widgets you've got that you think have certain influence on battery life.
Background: Any apps you've got running on background.
Connectivity: 3G signal + strengths or weaknesses / Wifi / Bluetooth.
Sync enabled?: Pretty self explanatory.
GPS & navigation: What software do you use for navigation.
Others: Screen brightness, display % usage, etc..
Battery-related:Battery model: HTC stock, ebay, whatever...
Charging method: What kind of charger are you using?
Extra info: Voltage, temp, and any other info worth providing.
Overall phone use: (Time-wise)
Internet (Browsing): How much time you spend *JUST* on your browser.
Internet (General): IM, VoIP, streaming... Basically any app you frequently use that requires connection.
Calling: Approximate total time per charge.
GPS & navigation: Do you use it frequently? If so, how much.
Games: Which games and for how long do you usually play.
Other: Any apps you may want to point out.
Battery life & impressions:
Here is where the real, but somewhat subjective, talk comes in. Just post what battery life you're getting with the info you've just provided and what are your concerns and impressions regarding this. This is the place to comment in more detail about anything you may have posted above and want to clarify or drive special attention to.

Leave whatever you don't want to post blank, but please be as specific and objective as you can on what you do post. Also, feel free to add any category with info you think is worth it. If you think there's something that I left out and should be there (which is very likely I have) please don't hesitate to tell me and I'll add it as soon as I read it.
I really hope we can all share some info and clear out all the secrets regarding mysterious claims for battery life I've seen around lately. For this to work I urge you once again to post in a clear and organized manner. There's quite a lot of information and it'll be much easier to find, compare, and comment on.
Thanks in advance for your participation.

I'll try and post the best results here once we've got enough impressions.
What happened to this thread???? No one replied?
I think the idea is awesome, however the information you ask might be a bit too detailed. I would rather try to classify uses under "light", "medium" and "heavy" (i.e. light would be just occasional phone and messaging, medium would be more frequent messaging with occasional data/gps/wifi....etc.) That way, someone could easily classify himself along these criteria and we would get a very large database of battery life for each rom and use. I'm sure a lot of people would chime in on this as battery life is very important to all of us.
For me, it's too early to give my opinion as I just got the phone and installed CM, but I am a little bit disappointed at the battery life... I definitely won't be keeping the display brightness on auto...
Hey thanks for replying!
I created this thread because in such a phone, battery life is an issue that we're all concerned about. Now, with so many different ROMs/Kernels to choose from, it's sometimes difficult to know which will suit you the best in these terms.
I never said every category I mentioned had to be answered. They're kind of a guide if you will. Just answer whatever you feel like answering, or make a simple comment if you feel lazy. I don't really care as long as the discussion stays on topic.
I think once we've got some participation this thread will grow exponentially. I just can't believe people don't give a **** about they're $500+ "superphone"'s battery.
ROM: CM 5.0.5.3
Kernel: intersectRavens 33.1 AVS Extra
System & software related:
Widgets: Weather widget donate, Battery Life, Agenda Widget, Audio Manager, Power Control, IP Address
Background: Wallpaper rotator(60 mins), SeePU, SetCPU, AppSwipe, GTalk, Meebo, Google Voice, Gestures, Swype
Connectivity: 2G only for 2 more weeks
Sync enabled?: Yes
GPS & navigation: Motonav about twice a week.
Others: 0% Brightness except in the sun, Display usage ranges from 20% to 60%
Battery-related:
Battery model: ends with M
Charging method: 500mA USB usually
Extra info:
Overall phone use: (Time-wise)
I'm a heavy user. The battery will die in under 4 hours if I use it constantly.
Internet (Browsing):
Internet (General): gmail,gvoice,im, xda, fmylife
Calling: about 30 mins per day.
GPS & navigation: not too much, all of them drain the battery fast.
Games: RoboDefence (level 70 , drains the battery quickly, choppy with power save kernels), AirControl. Whenever theres time to kill
Other: Camera.(tried desire, back on stock now). Shoot anything and everything. Very fast way to empty your battery.
Battery life & impressions:
Have to carry a charger on me whenever I go out for an extended period (5 hrs). Noticed some improvement in standby time with the new AVS kernel.
Waiting to try the release version of CM 5.0.6 or 5.0.7;logs indicate power saving is a priority now.
The information contained in this thread is not my own work. It is simply a collaboration of the links, guides, and information I have found on the web as I try and optimize my own Evo battery to maximum performance. This guide assumes that you already have a rooted Evo, if not I would suggest heading over to the developer's section for a guide on that.
Please note I have NOT been able to test out the outcomes of all these guides so the amount of battery you save will be very YMMV. For the most part though, I don't see any of these guides harming your battery life so they are worth trying. My Evo battery is able to last 10+ hours on moderate/high use, and over 20 hours on idle through the help of some of these guides.
Let me know if you want anything added up here!

So over at android central here is what is posted. This was a conversation with a member and the developer. Where it says bills info he is the developer of this app and his statement. So it appears it does help.
Obviously it can't overclock, we all know that because of perflock BUT here's the deal, the EVO CPU is set to scale back when its sleeping by default although it doesn't always do this because it may misinterpret information.
(bills info)
What this widget does is force it to underclock so you may see a slight increase in battery.

There have been mixed reviews on how well that modification is working. I would say keep a close eye on your battery levels when you attempt this. I tried, and my battery dropped 23% in 15 minutes right after I took it off a fresh charge. I'm not sure if it was the overclocking widget causing this or something else but there has been a lot of varying results. I'll have to test it out again later.
Goodluck to you!
It should be noted that the "overclocking" is actually underclocking, which the EVO does automatically. There is no need for an additional widget to control this.
Sticky IMO
Changed the section to be overclocking/underclocking.
Also added Flip's rom to the list, as I've been keeping up with that thread and it seems like a lot of users are reporting substantial performance gains.
Let me know if there's anything else that needs to be added!
*** NOTE ***
I just realized i posted to the Nexus One forum, not Galaxy Nexus as i had intended..
Hello everyone
I thought i should share what i just discovered. I disabled the syncing of facebook contacts, and my battery usage seems to have dropped significantly.
I have deactivated the autosync and notifications in the facebook app ages ago. The only change now was that in "Accounts and sync".
The first ~8h of my battery history is during the night (see attached screenshots)
Although our devices are different, I have to agree with you on the sync and battery issues. I use Facebook a lot and would love auto syncing, but it hits the battery too hard. What I did was disable syncing in settings>accounts and in the Facebook app it's self. I noticed that my battery drained at a much lower rate after doing this. Another think you can do is lower the frequency at which the app updates; but still there will be the update service running and your battery will continue to drain.
Welcome to the N1 section
Thanks
Still waiting for the day battery issues are a distant memory..
Yea, smartphones are great and all, but battery always sucks. We need a company to create a new technology to make them smaller and more efficient. What mAh size is the G Nexus's battery?
Big screens, multiple accounts and some application polling to get notification drains battery significantly. Day will come when there ll be batteries which will last more..

It has a 1750 mAh battery.
I think a methanol fuel cell would be nice. Methanol is 15 times more energy dense than a Lithium Ion battery. The only problem is making a small and safe enough fuel cell.
I think I am having the same issue with my Nexus One running stock 2.3.6. The past few days, I've noticed that my battery has been draining very fast. Normally, I had gotten a solid two days on a charge, but now I'm lucky if I'm getting an entire day on one charge. I haven't changed my usage habits at all. I had noticed that the Facebook app had notifications enabled and was checking for notifications once an hour. I disabled notifications, but the battery drain seems to be continuing. I've checked for other apps that may have gotten updated which are looking for notifications, but nothing else seems to have been changed.

Dear All,
Its been quiet some time trying to do enough experiments with custom ROM, battery life apk and all that can tweak CPU....seems a solution is getting into place. My device started giving a decent battery life, of 3% drop for an idle usage time of 8 hrs. Things done as below:
1. Root - Yes required
2. Good Custom ROM - using currently Ultimate ROM - thanks to the developer, its a great ROM
3. Install Greenify - this is one apk you will love unlike other task killing apk, hibernation is better
4. Install CPU Spy - Come with default with this ROM
5. Juice defender - just to ensure be sure all things are controlled.
Thats it, your device is ready to rock. I charged to 75% battery before sleeping, disabled of course Wifi and other data and removed all unnecessary task killers, battery managers etc. Gave a 3% dip in battery after 8 hrs. Post that a charge of again to 75% with a normal usage of calls( around 10 calls average talk time of 2 minutes), Wifi for reading mails and still the battery 15% after using for 5 hrs !!!. Earlier this used to tank in 3 hrs, so i believe a decent battery time.
Hope it helps readers to address battery issue.
Mine gives 1 percent drop full night maybe 8 hrs without any mods.
Maybe I know which rom and kernel. Thanks.

What's a difference if I will use 1% or 3% over night if in 1h of web browsing or gaming will loose 30%?
For heavy users benefits are negligible. Few mA on undervolting few on lowering brightness and black theme but still the screen is the hugest drain and rest is nothing if you do not have wake-locks. Most of the time my screen uses 60-70% with all connectivity enabled and no juice saving apps and no matter how many tweaks applied, we have to live with screen consuming a lot of juice even on minimum brightness. Liked a lot juice defender on hd2, now on note not much difference.

Thanks all for your feedback. Yes its true in any case we will have less than 3% drop if left idle, but i tried to check battery usage, "Screen usage" is high if used for a full time, earlier it was "Android" using more. Anyways thanks all for you information. AS Nigi mentioned we just have to live with it - No matter what we do, if for a day it works with 15% battery remaining it would be just sufficient.
Any lo!!!! Hear S4 is on the move - With octacore and DDR3 RAM. May be its going to be a gamechanger in saving battery !!!!

Galaxy Note has a large enough battery to standby for days (Official: 32 days on 3G, 40 days on 2G) without tweakings or modings. On ICS Stock ROM on airplane mode, during the night, a 100% battery remains 100% the morning after. I don't know what else I could have asked for a better battery performance out of my phone.
To get the best performance out of any smartphone one has to layout the expectations first and then become technically educated with the basics "properly" before changing usage habbits.
Laying out the expectations
Choosing a 5.3" device when smaller screen sizes were already available dictates the specific requirements one had. These could be physical (i.e., big hands, bad eyes), usage (i.e., reading and writing for long period of times, playing games, watching videos), or seeking differentiation (i.e., showing off, standing out).
When you know why you purchased Galaxy Note then we can move on to the technical stuff.
Technical - Basics
Bigger screens draw more power, the brighter the screen is the more power it needs. These are scientific facts and Galaxy Note's screen by no means is power efficient.
Web Browsing is the most, if not one of, task intensive job one can execute with his or hers Galaxy Note. Often Original Note scores poorly in web browsing benchmarks and this is not down to the screen size alone. When the CPU has the right sets of instructions corresponding tasks are performed much faster and with more power effiency. In my opinion the Exynos CPU used in Original Note does not support the crucial instructions in regards to the Web Browsing related processes and something is wrong with the internal flash disk components, be it software, hardware or both. Samsung has so far resisted in releasing its Exynos's source codes and I'm suspicious they have something to hide.
On the other hand, Note II offers excellent Web Browsing benchmark results, even better than the newly released Qualcomm 600 CPU. The battery capacity in Note II is not twice as Original Note but battery performance is almost twice as much in many respects. The overclocked Mali-400, 440MHz from 266MHz, in Note II should drain battery more but the CPU which is based on the same ARM architecture (ARMv7, ARM Coretex-A9) provides far better power efficiency. Thanks to the smaller semiconductor in Exynos 4412 (SGIII and Note II) which is 32nm versus SGII and Note's Exynos 4210 which is 45nm. The smaller nm number is the lower power consumption is.
There is no magic wand that can make Original Note more power efficient as it is. So no matter one does there is no way web browsing can be streched by more than 10 to 15 minutes in low screen brightness, period. Four hours is what we all get.
Change of habbits
Now that we understand there is a power capacity that cannot be stretched we however, can change habbits to get the maximum performance out of Note.
I adamantly opposed any software utility as a solution to extend the battery performance. They come at a cost which is not justified. I don't wish to go through the details but a simple daily reboot which is also recommended by the manufacturers will do the job these software claim to do. These apps mainly free memory while consuming battery.
Be sensible in choosing apps, be responsible in managing them. Once you realise the real reason you own a smartphone your choice for apps will be narrowed down anyway. Monitor the impacts of the newly apps on RAM and overall performance of your phone and then decide whether the app stays or goes.
Google Play app is a culprit to many issues. Literally Google Play is connected to various services for different reasons. One of GP's job is to check for app updates. The more apps installed the more battery is consumed to run the checks, download the updates, and finally installing them.
Be smarter than your smartphones.

Why are people so excited by a little battery drain during the night while wi-fi and data are shut down?
My matter is not having a long life battery on a phone I don't use and I find the night is the best moment to have my phone plugged and to let all applications updates and massive data exchanges be done.
My matter is to have the best battery life during the day when I'm on the my way and use the phone, browse, take pictures and films, send and read sms and mails, use GPS, read books and magazines, watch movies or listen to music.

I want both.
wakelocks = most common issue in standby battery life. Almost everyone encounters them and once they know how to analyze that (ahalfords sticky q&a section) that can be minimized
When awake, tons of other stuff n tweaks.
Both should not enhibit daily functioning. The moment I dont have the feeling, oh I need to not use the phone because I will have no juice is or I need to charge it/swap batteries is the moment I dream for. Such pda's dont exist yet. Not without changing ridiculously behaviour/usage and/or charging. Devices arent there yet. Soon they will.
However, its pretty good now with new battery and changing. I have had far worse lol.

Best way to increase your battery life is just to buy a new battery, get stock JB and decrease screen brightness.

For one, Atom Launcher seems to be a hog. Disable any apps/services you don't use such as S Health and News
I use both apps? I have them in always power save? Atom launcher is my default launcher so wasn't problem before
after flashing anything wait a day or two for the battery usage to stabilize before criticizing battery usage.
As the battery needs time to optimize for the new operatong system and any new apps.
Agree with @dynospectrum, any launcher that's using 10% of your battery is a hog. I remember users saying the same about Atom back in my Note 3 days.
As for the rest - hard to say objectively. A lot of sync going on and your MSN feed is demanding, but I sync nothing and my BBC news feed isn't a resource hog. YMMV.
OK just to be clear I didn't flash this morning it's been about 4days hence me noticing here are screen shots from a whole day
