I bought a SG2 some time ago and loved it except for the idle battery drain. For the life of me, I couldn't seem to get it to stop chewing battery when it wasn't being used. I even tested it by charging it to full and leaving it overnight. It lost about 20%.
Remembering that the iPhone 4 had excellent idle battery life, I decided to give it another go just for the hell of it. I hate iOS as a daily driver, but I figured at least I wouldn't have to worry about battery life.
These are my observations:
1) Idle time on iPhone 4 is indeed better. When it's not being used, it uses no battery. However, when being used heavily, the SG2 actually seems to get BETTER battery life than iPhone 4 when it is being used heavily. Not sure why.
2) I severely miss being able to send/upload high quality videos and pictures. I hate the restrictions that Apple places on file size. I don't always have wifi readily available and at least with Android, you can upload large videos to Youtube over the cell connection.
3) I miss the integration in the photo album with social services. It's annoying having to launch an app every time I want to upload a picture/video.
4) The camera on the SG2 is definitely better. You get more fine detail on objects that are further away, no doubt due to the higher megapixel count.
5) I think most apps on iOS look better and are more functional, but the problem is, you have to launch an app to do anything in iOS.
I really wish Samsung (and maybe Google in general) could solve the idle battery drain. Losing 20% over 8 hours without even using the phone seems rather high when you factor in that you'll be losing that battery life whether you use the phone or not. Theoretically, this should mean that the iPhone would get better battery life with the same use, but I'm not finding that to be the case so far. I will probably be going back to my SG2 very soon.
Sorry for the long-winded post. Just wanted to collect my thoughts and present my personal findings.
U r right about battery consumption .
But i m sure Android is going to be so much improved and vast in features that we cant compare to any os in the world in future.
Biggest plus of Android is community like this and the freedom to change things inside it.
agree on most of the things u said there
but
when it comes to battery life i have no idea why its soo random with some people
i lose about 1% an hour on KE2
(stock was on the phone when i bought it no root )
but since i installed KF3
i lose about 2% an hour
rooted flashed from odin
I must have responded to 10+ questions on this forum in the last 24 hours as regards battery drain, i get 25+ hours on my GS2, if you search on here you will find many tips that will substantially increase your battery life.
check the new kernel ninephetamine. Have used the modified 1.4v (with deep sleep enabled).....promising results with undervolting.
Currently OC 1400, and undervolted.
Simple Answer
Iphone does not loose batter on idle cause it puts all apps to sleep state if not used for a while
Android phones in general are always using data for like your emails, facebook, etc if you have set the apps to connect say every hour or so
IF you leave WIFI on it takes up battery as well
I am quiet happy with my SGS2 ( 12 -15 hours ) heavy usage and I am used to daily charging. and its just the day time hours unlike people who may be posting their night time hours as well which add anything form 8-16 more

I'm not interested in disabling everything that makes Android what it is. If I have to modify it to the point that it's an iPhone, I might as well use an iPhone. I'm well aware of battery saving tips for Android. They almost always involve shutting down all automated services and anything that retrieves data. This is not a solution. I have some e-mail accounts on periodic pull and the most important ones on push. On the iPhone, I have all e-mail accounts on Push.
I also don't particularly want to use a custom ROM. I prefer to stay stock.
I'm not getting horrible battery life on my SG2. In fact, I get around 15 hours with the same kind of use as that on the iPhone 4. I would just like to be able to set the phone down for several hours and not lose a quarter of the battery.
i have tried every single battery optimisation and calibration tricks on my Android phones. My first Android phone was a htc hero, second SE X10 and Now Galaxy S2.
All the optimisation and stuff works if you sacrifice something on your phone. i like my display to be sharp and easy to see. I want my email notification to be prompt and so many other things.
I used to be Windows mobile user my last handset was Toshiba TG01. i never ever had any battery issue.
It is to do with Android system, it needs to improve. it has all the pace now and so many chances.
if this roumor is true then IOS will shrink sooner than 2015:

Why my Lamborghini needs more fuel than my Fiat Panda? I can't understand. Crappy Lamborghini, back on Panda.
Well if riding the Panda can get me through the jungle instead of half of it, why not?
Also, the Panda can get me more food via the App Store.
Granted though the Lamborghini has alot more fancy features and doesnt have mindless sheep following it
Anyway, coming from an SGS1, then an iPhone4, I heartily agree with the OP. Android is awesome but it's still rough around the edges. Sometimes the ease and boring simplicity of IOS is something that I miss, along with the Apps and definitely the games which Android is sorely lacking.
But then again I'd be reminded of steve and his itunes bloatware. ugh
Yes, but when Lamborghini is parked it should use the same as the Panda! (I.e. zero.)
Google really should minimise the stuff going on when the phone is idle. Google also needs to do something about all these rouge apps that always start up services that always run in the background. They should provide some way of limiting/stopping the CPU usage of apps running in the background.
Even the official XDA forum app still servers up adverts in the background eating up your battery (and bandwidth) if you press home instead of backup to exit.
wifi sharing is a bit of a bug that drains battery like crazy. If your not rooted thats definitely the screen off battery drain for sure. If there was a reason to root, just root to freeze that one rogue app.

But most of the stuff is pretty useless anyway all this Samsung bloatware is guaranteed to drain your battery, i don't see it as sacrifcying anything, ive got email on push and i still get over 25+ hours battery,i used an iPhone 4 for a few weeks and id be lucky to get 16 hours with medium to heavy usage.
My data is always enabled too, you can save a lot of battery if you use apps like Juice defender plus and system panel will also tell you which apps,etc are using up more than others.
At the end of the day smartphones are always going to use up much more battery than normal phones and this isn't going to change anytime soon until such time a revoultionary new battery is designed that lasts for days on end.
Until then people have to deal with it,follow the tips and you'll get good battery life, if you want absolutely everything "on at the same time" your simply not going to get it, not on the iPhone 4 or any phone.

Has not been properly addressed. Thats why its not even included in 90% of the custom roms.
I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)
I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!
Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol
1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.
1 personally run ninja speed freak, i get amazing battery life. simply amazing, days on worth of battery!
it is not a kernel issue, i simply dont know exactcly what hack in particular gives ninja the amazing battery life. but im working hard to determing this so i can share it.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.
I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.
Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .
The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).
These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.
Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) then my bad bro!

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.

Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.

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 !!!!

Thanks.
I have the 4.1.2 rom Netherlands with root and installed Greenify, this alone was enough for me and I must admit I'm impressed with the result ... Battery lasting extraordinary.
Thankful.

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.

If you are rooted, uninstall gmaps updates first then remove GMS_Maps.apk from /system/app folder. Reboot and reinstall it from Google Play as downloaded app. Good Luck!
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.
Posté depuis mobile.
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.

Hi Bongski55....are you having Ultimate Jelly Bean ROM with LSF firmware...if so can you share the link please. I would like to try.
Best way to increase your battery life is just to buy a new battery, get stock JB and decrease screen brightness.

Are you using the ultimate jellybean rom? Just for clarification.
But do you find that the ram is getting used up quickly leaving only ~100MB free? If yes, may i ask if you solved it with greenify? I'll be trying it too now but i'll like to see whether u have this prob and how you solved it. Thanks.

Hey everyone. Without further a do, I am saying that my N4 battery suuuuucks really bad. Started on stock rom, flashed Chroma w/ latest franco kernel. Nope. Still lots of drain (slightly better overall, but nothibg major). Then flashed hells doctor kernel. Nope. Lots of drain when screen is on, but stable with screen off.
Honestly, I've seen people getting 6h on screen time. And everyone says that these kernels and rom can increase battery life by a margin, while mine stays the same.
Oh and there is a thing. Ive recently broke my stock charger and now using apple's ipad charger. Mine was 1.2 A and the one from apple is 1 A. Is this is an issue we are looking for?
Or its just a 2years old battery running out of its life cycles...?
Thank you!

Nexus 4 battere sucks really no matter what you plus your network coverage may impact vastly on performance. Anyway given the battery is 2 years old, I would say it's gone even if it says it's good but again it depends on your usage like continuous tethering or other heavy activity that makes the phone run hot

Well my usage can be heavy surfing on FB, Instagram and definetely FB messenger. I often use chrome and mainly everything is done under Wifi.
According to my screenshots, you cannclearly see that shes (battery) is ok when screen is off, no drain and etc. As soon I start using it it drains A LOT. Almost 90° angle on diagram It's crazy.
Plot twist: To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages.
Yes, i have a new battery which was working well, but I flashed factory image 5.1.1 xxx47v and the batt life is really horrible now.
It's easy to replace the battery, I recommend taking out the sim card tray before taking the back off though.
I haven't been on here for a long time, whats the best rom, for batt life. I'm willing to go back to kit kat if I have to .
Also note that some of the screenshots with 6+ hours of SOT the user has handicapped their devices (disable 2 cores, lower max cpu/gpu frequency, etc).
