I haven't ever had FANTASTIC battery life like I'm seeing from some folks around here... when I first started on Starburst (I didn't keep stock for more than about four hours), I was at around 70% at the same time. I'm currently on Calkulin's 2.0.0; about to revert to Starburst and see if it's ROM-related, now that I've given Calkulin's about a week with a calibration to no effect.
I'm currently undervolted by -75 on all steps, and this seems to have made it WORSE if anything, which I didn't think was possible for undervolting to do. I've been monitoring things fairly closely with Watchdog, and nothing jumps out at me. The phone signal in the pic doesn't look good, but I've been in all the same places as I was when I was getting much better life.
What interests me is that I'm seeing absolutely no usage-based change in battery life. Until that sudden dip you see up there, it was going down at the exact same rate whether I was using it or it was sitting on my desk doing absolutely nothing.
That dip started after I played Fieldrunners HD for about ten minutes during a break at work. After I stopped playing, battery life went into a continuous plummet.
I use Tasker (extensively) to keep things in check; generally speaking, nothing is active unless it needs to be, except for Wi-Fi which is always active as it's my primary method of detecting my locations.
Am I missing something simple-stupid here? If not, anyone got any ideas, assuming going back to Starburst doesn't magically fix it?

Not sure if this will help, but improved my battery.
(1) go to your email setting for each account and change sync update, I believe by default it's set up to check every 15 minutes. With 10 email accounts, it took a toll on my my battery. I changed all my accounts to 4 hours.
(2) best way to kill a task is by holding down home button, going to task manager and kill from there. Market task killers were making things worse for me.
Hope this helps.

Thanks for the thoughts! Sadly, neither of those really apply in my case. I stick with with the default Gmail app, which is all push, and I don't use task killers at all.

I'm running the stock rom with a custom kernel. I did notice that as soon as I went from stock to a different kernel I started to lose battery life. Maybe its something Samsung did? I am still a novice with Roms and what not, but nothing like this happened on my original Epic or my Hero. Maybe the yellow triangle isn't the only thing Samsung put in there.

Maybe the aggressive undervolt is causing your phone to ramp up to a higher state to perform the tasks? That drop is steep with how little screen on time you have

For as little as I know, that certainly sounds logical. I still wasn't getting as good as I would've expected even the UV, though.
I just flashed the EK02 modem with today's wonderful developments; I'm going to wait and see if that gets me better reception and thus better life. If not... now I'm not sure whether to try the new ROM first, or scale back the UVs. I want to try one thing at a time, since it's not urgent that I have good battery life ASAP. This gets me through my day, currently, more or less; I'd like to try and find my root cause so that I'm not just trying things wildly in the future.

Well, the good thing is that as of today, its possible to return back to bone stock and start again so you can mess with a few setups and see what works best for you. I have found that this is the first phone that uses the frequencies well. I haven't undervolted at all yet and I have had great battery life. I did the standard delete Sprint bloat, Social Hub and associated apps, Maps, etc. Also, get BetterBatteryStats. It may give you some insight into what's happening.

How you return to bone stock? By applying the update?

Then update to EK02

Got very slightly better today after flashing the EK02 kernel. 23% at the same time instead of 18%... anything could account for that 5%, though, so I don't really think EK02 had any effect on this. Zedomax kernel with stock voltages is next.

CPU boots pro
(From the market & assuming your rooted)
Settings
~Screen off profile max800 min200
~GPU to Conservative max1000 min800
~Nitrous Widget GPU to on demand max1400 min1000
What this should do is downclock your device when on standby by alot. Second for phone calls and daily stuff a clock of 1k will be silky smooth and be a small downclock. Third when you set up the nitrous widget and activate it you will overclock to 1.4k which is stoopid fast my quad score is at 1.4k I get 4500 scores at 1.6k oc but forget batt when I'm using the nitrous. I like too personally keep my phone at a clock of 800 for daily phone calls and web surfing... if I play a graphic intense game ill oc it with nitrous and not worry about burning up my phone because if I set the phone down it downclocks as soon as it stands by and will pick right back up when I'm ready.
Hope it helps here's pics.

If you're talking about the page I think you are, it'll have to wait until at least morning. I just did a full charge.
To wit... I spent 43 minutes on a phone call, and lost almost the same as what I normally lose in that same time period. 6% for a 43 minute call; I'm averaging 5%/hr loss doing NOTHING.
@Dchibro, assuming that's true, what would it mean for me? Does it give me a solution?

So, doing a bit of my own detective work... I've had Watchdog installed for about three days, with aggressive monitoring. I was almost immediately getting a bunch of alerts for two processes:
I initially whitelisted them through Watchdog, dismissing them as system processes that unavoidably needed to run. However, the comment from Dchibro got me thinking and sent me back to those, and I started Googling around. Here's what I've turned up so far:
http://goo.gl/Hsvej (HUGE thread on the issue in SGS2 forums. Haven't had a chance to go through all this yet.)
http://goo.gl/kUcqx (SGS2 forums.)
http://goo.gl/mlWW4 (Nook Color forums.)
http://goo.gl/mNiId (My Google search results.)
Gonna try some of the suggestions on here and see what I turn up. For now, I'm returning to stock voltages, implementing a bunch of those changes and keeping everything else as it is now to see where I end up. Phone will be charged to 100% before bed tonight, and I'll post sometime tomorrow with my findings.
Wish me luck!

So, in stead of waking up to 50% this morning, I woke up to 86%! Which is the same I went to bed at. Six hours of sleep, not a single percent lost. If nothing else, I learned from all this that I can reboot the phone when this bug hits me and and get away from it.

As I suspected. Your Watchdog shot clearly shows that you are/were (sounds like a reboot solved your issue at least temporarily) suffering from the Android OS bug. This bug presents itself most prominently in the suspend and events/0 processes. Unfortunately, a conclusive solution has not been found, but there are some things you can do to hunt the problem down.

Im one week into my new sgs2 running full stock. What should normal battery use be? I feel my battery drains too fast. Here is my usage summary since full charge couple hours ago.
I charged too 100%, shutdown, then charged to 100%, powered up and used the phone very sparingly since. Battery is at 91%

Definitely seeing a bit of an improvement, here.
Watchdog alerted me to the suspend and event/0 stuff again about an hour ago, but I quickly rebooted and nothing seems to have come of it. I'm going to try to make a Tasker profile to do this automatically, kinda like Viper's LoS script.
All in all, I'm considering this a mostly satisfactory alternative to draining 80% of my battery with almost no use in eight hours.

Before we all jump to Nexus 4, are we sure Google has killed the battery vampires?

I've had the Galaxy Nexus LTE for nearly 11 months on Verizon. I've done what I can to stem battery drain. At some point, I just gave up diagnosing the problem and started carrying 5-6 spare batteries with me. Some people claim one day's use; others report the same problems. I think it all depends on how we use our phones--eg do you take a lot of pictures--and what apps we have installed. I use the phone hard but not that hard. Sometimes the phone will burn the battery just being in the pocket.
I don't want this to be another Galaxy Nexus battery life sucks thread. What I want to know is whether the battery drain problem will be solved before we consider moving onto phones running 4.2.
Some of the drain is due to the terrible LTE radio. Phones with integrated chips have much less hardware drain.
But about the software drain? When I run GSam Battery Monitor, the number culprits seem to be Media Scanner (Server?), acore processes--contacts, user dictionary.
I've dialed down or turned off syncs as far as I reasonably can; are rogue apps causing problems or is the OS too easy to trip up?
If you search http://code.google.com/p/android/issues/list for "media battery," you see a lot of bug reports about the problem.
The Google Android team doesn't seem to care about these problems.

"I'm only posting this here for my own amusement. My track record with Android bug reports is that Google ignores them for 2 years and then closes them without taking any corrective action. Good luck everyone."

http://code.google.com/p/android/issues/detail?id=18115
4.1.2 has the os drain:
http://code.google.com/p/android/issues/detail?id=38720
Going into 4.2, how do we track these issues and see if they are getting fixed? I'm not a dev... The only way we can see the 4.2 source and commits is to clone the repo using git? Is there a friendly web interact through which we can see the changes?
Do we wait until 4.2 is released and see what defects are reported on the issue tracker?
Please don't let this be a typical battery life sucks thread, where people will
1) complain that they also have bad battery life
2) complaint that they have great battery life and don't see these problems
3) suggest debugging these problems with CPU SPY, BetterBatteryStats, etc
4) suggest fixing these problems with .nomedia
I want to know how we as users can track what Google is doing or has done to fix these problems in 4.2, so we, as Android devotees, can have faith in migrating to those devices.

Any Tom, ****, or Harry can post issues. Most of the time they don't have the technical knowledge to even know what a bug is. Don't confuse Google not caring vs. Google not willing to accept a ticket caused by something out of their control.
As for your case, you have a Verizon Nexus. They ALL suck on battery compared to other devices.
You say you don't want this to devolve into a typical battery thread but it will.

no lte in the nexus 4, sounds like they chased off the battery sucker to me.

I'd you're using your phone as a laptop, it's time to buy a laptop. Otherwise, the turn if syncing for things you use once a day. Actively using data (especially over LTE) with a large screen burns battery on any device. If you are burning battery in your pocket, you either need to sync less or identify the rogue app that is doing the work. And Google does use the bug reports to make improvements. A recent bug in Chrome removed names from the shortcuts in the bookmarks bar and it was fixed within a week. Android rakes longer due to the wide spectrum of devices and overall update process. Bugs in an OS are a different beast than bugs in a browser.
From the sounds of things, you will have battery issues on any device.

Go by the evidence. The Media Server / Scanner drain problem still exists in 4.1.2

Complaining about battery life on an LTE device is like dropping a 600HP engine in your car and complaining about your gas mileage going down.
So lets say an LTE phone has an enormous battery in it, this might give you "respectable" battery life... but take that same huge battery and put it in a GSM phone and watch the battery life go from "respectable" to "incredible".
If battery life is what you need... you might consider going GSM. With heavy use I usually end up at about 30-40% at the end of the day...
Of course, as stated above, the media scanner bug is still there... but from my experience, LTE is the biggest "battery vampire" by a landslide.

I can't wait to see how many "battery life sucks on N4" threads are created.

Honestly, it's just the way it is so ppl need to get over it. If they buy the Nexus and complain about the non-removable battery, then they should have gotten a different phone instead. Like an S3.

That's 4 days of actual on time (I turn it off at night, ~15 hours a day). That's closing in on what my old Nokia and Sony feature phones clocked in at.

First, turning it off at night, makes your "4 days" statement entirely false, automatically. Second, 1 hour 20 minutes screen on time is terrible, even for a known battery sucker like the gnex. Third, the only thing might slightly warrant a pardon for that screen on time, would be the fact that you did get over 2 days on it, if not for Fourth (and finally) the fact that your phone clearly shows that your didn't use it at all.

4 days of my use, where is there false information? Still on the same charge, 1 hour 41 mins now. 61 hours with real world use is not bad, especially since despite you seemingly knowing how I use my phone, I was using it for texting, a few calls, I used google maps, updated some stuff and other random crap. A lot can be done in an hour and a half.
And finally, the entire point of this thread is the android process sucking up battery, which is why I posted a picture showing the contrary. How about you find something credible to ***** about.

Maybe if you stop using that ugly, bloated, stupid ROM your Android process usage will be reduced.

Why is the battery so s***?

Hey there
I honestly gave up. I have been trying ROMs, kernels, tweaks, and everything but the battery life is just terrible.
I have mainly been using Team Venom's Viper ROM, though, and yesterday I decided to install Alex-V's kernel with s2w feature or w.e. It is supposed to work well with Viper and be very stable. However, I am not seeing it and the battery life seems to have gotten worse. Also some applications like File Explorer randomly quit (Application has stopped working).

My screen brightness is not even set to automatic, but very, very low so I don't know how it is eating 72% of the battery and why it dropped all that much in just 9 damn minutes!
Is there a way to uninstall Alex-V's kernel and get back the stock one that came with the ROM or do I have to reflash the ROM?
Thank you

If you are willing to take the time to read the OP's from the viper thread and read .....
You will find a venom flasher that flashes kernels fully automatic !
And a kernel has to adapt with a few charge cycles .... after a couple of days it should get more stable.
And the Alex-V kernel IS the stock kernel but he just added the S2W feature !

Thank you, mate. Would you be kind to explain to me what the swipe 2 wake feature is and does exactly? lol
I installed that kernel as a recommendation from someone who has been using Viper for a while, so I cannot say I took my time to read and learn about kernels in general, or Alex-V's specifically. And I viewed from page 1 to 5 but everyone seemed to be well acquainted with kernels and the S2W feature.

did not know it was that time again
and freaking search that is the only way you learn....or else you end up bricking your phone for not taking a couple of hours to read what you installing on your phone..and please do not say you do cause you clearly have not got a clue...or else you would not be asking the silly questions you are asking now

S2W will replace the need to press power or volume buttons in order to wake the device and light the screen.
It works by swiping left to right to wake the device, or right to left to send it to sleep mode.
The swipes are done on the 3 touch button panel on the bottom of your One X.
It'll work in the lockscreen.

However, no offense but whether my questions are 'silly' or not is pretty subjective and the reason why I am on the forum is to ask questions, learn, benefit from those who are more experienced, and eventually (hopefully) be able to help newbs like myself when they need something.

@One-x-master Thanks for explaining what the feature does. I don't think I'll ever need it, so I might be flashing the stock kernel again very soon. I'm going to wait a couple of days and let the kernel settle, however, and see if there are improvements in battery life and overall performance.

I would say it depends on owner's behavior. If he likes to hold the phone directly by hand, the kernel will consume amounts of battery.
Show-p did mentioned after screen off kernel sleep and touchscreen register remaining active, any contact will wake the kernel to check if the touches is the correct steps or else.

True ! And i forgot to mention that my phone is always in a pouch , so the buttons are not being touched in any way. :thumbup:

I cant talk about battery life...
My recovery eats most of it...

Hello, maybe you should try black pearl rom, that rom provided me 4hours and 15mins screan time on auto brightness and 3% left >.>( it was 1st charge after the rom was flashed), also i had a little bit over 1 hour of phone calls and 95% of the time phone was connected on a very poor wi-fi 2 bars tops and every 10-15mins discconected/reconected.
My usage was mainly reading stuff from XDA, facebook, some skype , few app downloads, mail (no sync at all) gsm network as well , not that i want 2g it's just i can't get 3g on my place lol, anyway if you cut the 1+ hour of talk time i'm sure i could've reach 5hours.
Anyway give it a try with stock kernel that comes with it . i'm currently on that rom but this time with NCX kernel and seams to give a little bit more juice, maybe i could get an extra 20 tops 30 more mins at screan on time with it.

Hahaha, sure bro, black pearl rocks:thumbup:
But what i meant is that i spent more time flashing stuff from recovery than giving the phone a normal use.
Btw, u should try skydragon rom

I have to speak against this, i ran the faux kernels and stock kernels without s2w and now i'm on Alex-v kernel and there is no big significant difference !
But this is just in my case, it is completely different with other users

Gotta agree with you..I don't have such a problem with battery life, even with s2w switched on..I've great battery life with Faux kernel and s2w..

16 day battery life

Hi guys.
I am trying to find out what everything can be turned off keep basic phone functionality to reach battery life that this phone deserves with nearly 5000 mah battery.
Curently i downclocked gpu turned all cores except one core limited to 400 mhz (with free kernel auditor in store).
phone is bit lazy ( like old android phones but still usable for basic functionality like picking a call or responding to sms)
but every time i need reasonable work i enable 2 big cores. with just 2 taps and when done turn them off.
As for services i disabled pretty much everything and left only minimum 7 services running as seen on screenshots. also do not disable location services or phone will not boot. killing them after boot is enough it seems.
I enable google play services + play store + download manager just when i need to download/update some app and disable them afterwards
for fast enabling/disabling most used services i use free package disabler from store and keep them in his favorites. too bad his widgets dont work on my device. also it doesnt stop services after disabling so i stop them wih force stop helper.
in developer options i disabled background services and enabled gpu acceleration for 2d.
this is second time i am trying to reach 16 days and I am in the middle.
what would elevate battery life for a little bit longer is if I guess if I can lets say each 9min be on airplane mode with 1 min airplane off to catch missed calls sms.
i remember i did pulse airplane mode from cron with script and build in utils but i guess that would require cron running in background whole time which i dont like.
Is it possible to launch timed events based on hw timer without having an app running?
I love cpu tuner that has exactly that airplane pulsing but each time it pulses it crashes. if i only knew why.
Also is it possible to find out what service on folowing screenshots eaten how much cpu and why ?
thx guys. hopefully i will reach more than 16 days with your help.

I just have one question... Why? This phone already has an amazing battery. Why kill functionality for a marginal increase in battery?

I am not sure I would call2 days fantastic battery life. Also I dont think I sacrificed that many functionality. If i need camera i enable it in one tap i need play store i enable it etc.
Now is this litle incovenience worth aditional 13 days for me definitely yes.
also how come phone lasts 2 days before and 16 days after ? this is definitely waste and governors are not equal to core shutdowns i guess
After some time when i will reach maximum . lets say 20 days ?
Only then I will start reenabling minimum common sense features like pulse wifi and email at specific intervals.
In the end when I will have more clear idea what services are draining battery unnecessarily I will try to code something that pulses wifi plus disables cores/services when screen is off.

I don't understand you, what’s the problem by charging it every 2 days and no need to limit it.I prefer it fast and no missing any call or sms,I've just frezzed some apps that I use rarely and others to stay active in background.

The OP clearly has a project where he wants to maximize every joule of energy available to him - which is a very noble endeavor. We live in societies which are all too happy to waste the resources available to them - the case in point here is that we have two posters quoted above who think that wasting energy is somehow acceptable - and charging up the device more than necessary is perfectly fine.
Whatever the reason the OP has decided to pursue this endeavor, it is in the spirit of XDA that we encourage and help, if we can. It is not for us to batter the aspirations of another member, purely because we don't understand the motives of their pursuit. This is a community and the only way it will thrive is if we encourage the curiosity and passion that has driven us so far.

You may be right but from my point of view what for I need a movil phone if I can't receive a call or a sms at the moment?By removing the Sim, without using any app and turning off data and wifi you can get too about a week without charging but then it has no sense.

I think enabling 2 big cores is unnecessary for your purposes, just allow the small cores to clock up to 0.8-1ghz when you need work done. If your phone is 'lazy' with 1 core clocked @400mhz you're wasting screen on power whilst waiting for the 400mhz to do its thing.

Updates?

Thx panyan for warm support. I also think that xda is fantastic place for all kinds of tinkerers and experimenters. who knows where most modern software in mobile phones would be if we had not places to evolve like XDA, a lot of features that are now in android or ios were firsp created and popularized by comunity as mods first. or firmwares that would not exist for older phones otherwise.

You are right. Thats great idea hopefully governor will be as efficient as manual throttling. Will definitely try that.
not much progress thou ;( can't push past 16th day.
Biggest drain right now is phone idle. are you guys aware of way to have finer power usage log ? ie what exactly is eating that cpu ?
Or mayby broadband chip is thirsty when sihnal is weak.
mayby airplane on for 5 mins when signal is weak would help. but right now I have not idea where the power is sinking. I am allready on 2g so maybe some 2g parameters to tinker with ?

currently I am getting 20~24 days of stand by time with network on, wifi off, no data. although I use the phone only as a back up and rarely use it. So the insane standby is expected

Elemental kernel & Android 10 settings

Can anyone help with elemental kernel settings? I left them all out of the box and battery is terrible... Looking for settings suggestions!

@cassato : This should be in Q&A section or possibly in a battery thread somewhere else on xda but definitely not in the development section. I do not mean that in a rude way at all. More of a heads up for you for the future.. XDA rules are we must do some serious searching first and if we find nothing on whatever it is somewhere here in XDA world then we can then put our detailed info into an appropriate section...
Your battery can wear out because of many different things!! There are MANY battery life threads all over xda. Your battery could be bad because our phones came out in 2016 or if you used an aftermarket charger they aren't rated like the ones our device came with that are made for our phones and generic chargers will mess up your battery because of this! If you have a 'not so good' signal it will cause the device to keep searching for a signal and that's a battery drainer. You could have some sort of virus on your device and that also can cause abnormal battery drain or you may have some apps that are running 24/7 in the background and that can and will also drain lots of battery. EX kernel is same as stock kernel pretty much as far as battery life goes unless you turn max power way down on cluster 1 and 2 and maybe use LKT magisk module and battery saving profile. Check out LKT! It can be found in downloads part of magisk manager or here on xda. Legendary kernel tweaks! Real kernel tweaks that work! I believe EX kernel is supported on LKT. You can read all about LKT more in magisk managers download section just toss in LKT on download and click it and it has links to the xda thread. There are LOTS of good reads on battery but I gaurantee you your issue is one of the things I speak of here. Process of elimination is what I'd do and I'd begin with the things that don't cost $$. ??
If you've used a charger other than your pixel charger I'd say grab a "new oem battery" online but make sure it's an original brand & a new real pixel oem battery before you purchase it if you get one. If you've never used another charger your battery can still be bad because it's old. There are battery test apps on Google play store, Accu Battery I believe is one. Maybe check that out.. Where you live what's your signal read? Lte discovery app will tell you your signal strength in your status bar. See if it stays weak alot of the time... Check your carrier online and see if maybe they're doing work in your area, maybe that can be a thing.. I've been there before. For apps that run often ElemetalX kernel manager app has a battery monitor in it that can be used to see what apps are draining what but regular ole Android will also tell you how much an app ran..etc ...Naptime and Servicely are some good battery saver apps that stop services that run that don't need to and make apps sleep faster and differently and they can and will save you some juice if that be the case. As far as virus's go there's no easy way around that. I always format data and wipe my internal storage and flash a factory image and keep nothing from before far as backed up apps go ...etc... And be sure and change your passwords on your accounts and do a good security checkup on everything. When an account gets hacked much of the time Google sign in records will have your device name as if you signed in with your phone but it's the hacker putting bogus info in to slip by and hopefully not be noticed so that they can keep gathering info.. I always delete devices off my account and start fresh if I believe I've been compromised. There is an app named 'Hacked' on Gplay it tells you if your accounts have been compromised. Pretty neat app! Lots of things can be the cause of abnormal battery drainage. Read up on everything you can on here. XDA has everything we'd ever want to know or need to know already typed out. I always do a Google search and add "XDA" at the end of whatever I'm searching for then bookmark the hell out of several sites and read read read. Search, read, learn,, and pass it on... Anyway good luck and I hope you get this figured out soon. Hope my short book about battery helps you out too. Haha! That's why I first came to XDA forums back when the og HTC Evo and the Galaxy S2 had just came out. Back then BBS , aka Better Battery Stats was where it was at! Android wasn't optimized like it is now. It's soooo much better than it used to be in that way.

thanks for all the info, I will check out LTK. I figured it was the kernel because the battery was fine before installing it and literally the next day it was pretty poor.

Also keep in mind that after installing a new kernel it takes a few days/battery cycles to settle and get accurate battery readings.. Did it seem to be better after that time you saw it drain really fast or did you switch setups before? I'm quite sure if you stayed on that said setup it would even out and things would be normal in 2-3 battery cycles and if not I'd check all possible reasons why starting with the no cost, like rogue apps and so on and ending with possible bad battery.. Flash LTK in magisk and select battery profile. That's what I use and I rake in anywhere from about 4 and a half 5 and a half hours screen on time, always.

Have you installed Busybox built with NDK magisk module? I'm on stock 10 now with EX and LKT and mine are not that way... Do you have some other things maybe installed that could be messing with it? Did you delete files on sdcard that may have been there from a past kernel?
