Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Since you didn't seem to realize, I thought I'd tell you. This thread was 5 months old before you posted in it...
lol
I just have my new Galaxy S2 and first thing I noted is that battery drain overnight in flight mode is significannt. I had a ZTE Blade which stayed in same % even for a whole weekend in flight mode, using CM 7 or the best GB cooked roms.
I tried many ROMs, including stock XWKK5, XILA2 and custom, doing a full wipe install and in every case they typically loose 3-5% in one night or 8-10% in one full day. Only ROM that seems to keep battery most inf flight mode CM 7, loosing some 2% in 24h (but more than ZTE Blade). Next better is The-GingerMod 0.8. I tried killing every running process in installed ROMs but consumption is still high.
In ZTE Blade made no sense turning off the phone at night since startup lost more battery, but with S2 it's better to turn it off if still has battery for another day.
I can understand that phone has some parts always running, and that S2 has a large screen that consumes more power than smaller phones, but I find strange that in flight mode, screen off, everything off there is such a difference with the ZTE Blade.
Any opinion about this?
I tend to put my phone in flight mode overnight (~8 hrs/because I like to sleep when I'm in bed ) and I normally lose 2% (0.25% per hr).
At the end of the day it's easy to overthink/stress/obsess about losing a few % overnight when you've got easy access to a charger most of the time. What I mean by this is you can spend a whole lot of time trying to find/chasing that extra couple of % in battery savings & either not find them or maybe only find 1-2%.
Obviously battery drain will depend on a whole bunch of factors not limited to kernel, rom, how you have your phone setup (apps & so on).
You may be experiencing wakelocks when the phone is in flight mode that might be causing the drain to be a bit higher than it could otherwise be. Get hold of BetterBatteryStats. Install it, read the thread on here devoted to it & you can post your wakelock details to that thread. There's a bunch of guys who post to the thread regularly (including the dev) who might be able to help you nail the wakelocks & maybe squeeze out a few % of savings.
I installed BetterBatteryStats but as for now my knowledge is very limited to decipher the processes, anyhow as I said I tried many ROMs after full wipe being intrigued for this behaviour, so they were clean installs with no app added, but I see that even custom ROMs if they're based on official and no removed apps have many things added in comparison to the more vanilla ROMs the Blade has. This explains why CM 7 (or The-GingerMod) s the one that drains less. Have not tried 'lite' ROMs whith removed apps.
Just wanted to decide if it's better to turn phone off at night or just put it in flight mode.

i am currently using a lite rom based on XILA2 and i have to say it is the best i have used hands down. I never use flight mode at night or anything else. All i do is choose the governor of my choice and that is it. Some governors have a screen off profile. That saves you having to add an extra profile in the cpu apps if you use one. Anyway choose a rom plus a kernel that gives you great battery and stick a governor that has a screen off profile and your phone will sleep like a baby
Now that you've installed BetterBatteryStats, charge your phone fully before you go to sleep, do a reboot & leave it in flight mode overnight as you have been.
If you want to find out if it's possible to squeeze out an extra few % of battery, have a read of the BetterBatteryStats thread on here (search for it), read the first page or so, and the last 10 pages. That will give you an idea of what screenshots you'll need to post/what info you'll need to provide for the guys in that thread to help you out.
As to whether it's better to turn the phone off or put it in flight mode @ night, you should realise there's no right answer to that. It's your phone after all. Battery life isn't the be all & end all as I hinted in my previous post. Obviously if you want/need your phone fully on at night (normal mode), then you're going to lose battery & you'll be happy to lose battery because your phone will be switched on. It's entirely up to you.

I can be a lot of things besides the kernel itself, for instance:
1. Sensors! Turn off motion sensors...
2. The lower cpu freq is too high. Use the lowerst possible value.
3. The cpu governor it switching to the higher cpu freq to quickly. Try interactive.
4. Constant updates of some programs, like Twitter or Facebook. Even if there is no network connection they still run on their scheduled times. I just turn them off.
Hope it helps!
Hi Everyone,
I've noticed a few other posters have indicated that wifi makes up an unusually large amount of their Prime's battery drain. Personally I'm seeing anywhere between 60-90% of battery usage being attributed to Wifi. Do we know if there are any commonalities in these cases? I'm on a fully stock .21 build with a C3 series Prime, and my battery life has in general not been amazing (6-8 hours off-dock MAX). Anyone else seeing similar outcomes?
Yep, there are quite a few threads about this already
The wifi power consumption is absolute insane. With wifi off the battery last as advertised... but with bt or wifi..... well...
Wish there was a way to select how much power we want to assign to the wifi as i have seen in another phones.
Im having similar issues, on and off.
Recently, Ive been messing around with new roms and and kernels and found out tinkering here and there that when the tablet is put to sleep, its supposed to go into deep sleep, this being what makes the tab super battery efficient when its sleeping
A quick test to see if its going to deep sleep is to download Cpu Spy free from the market, start it, go to options (top right) reset timers to get a fresh reading, put tab to sleep for 10 -20 secs, then turn on, go back to Cpu Spy, options Refresh. You should have a listing for deep sleep, which will tell you that deep sleep is at least working.
Every now and again i would test this, found out that sometimes deep sleep would not initiate, normally its ok straight after reboot, but after ive been using the tab (mind you, not always), and test deep sleep, i find that the tab would stay on a low clock speed rather then deep sleep, well 'low' being a relative term, i mean at some points, the tab wouldnt go below 475mhz even when idle.
When idle, ideally, the tabs if not doing anything intensive in the background, SHOULD go to the lowest CPU state, 102mhz, i think there is something, either system related or app related, thats forcing our primes to run at higher clock speeds and in some cases its not letting our primes go into deep sleep
I think using cpu spy, is a good tool to figure out what that might be, restart your tab, before doing anything, establish that your tab can go to deep sleep while sleeping and uses the lower cpu speeds when idle, and then test it everynow and again, if the issues come back, and you see a connection between a certain app or certain setting you've been using let someone know, chances are, it could be our culprit, in this case the best way to fix something is to find out what needs fixing.
I have already checked forDeepSleep issues but I have none, my tablet sleeps like it should and when turned off use very little energy... but man once it starts transfering data the battery goes to hell hehe (Music streaming, WebSurfing. anything that uses internet).
The battery used by WiFi is more evident when using the Prime in Eco Mode with the light turned all the way down, 80-90% is from WiFi :/
Changing the Policy to disconnect while the screen turns off just does noting for me, since I like I said before, it only uses so much power when transfering any kind of data.

Thanks for the info.
Just to get our ducks in order, do you test with CPU Spy after you have messed around with the tab, without closing or shutting down anything?
Most of the time, mine works as it should when 102mhz and deep sleep is concerned, but on occasion after playing around with it, i find that deep sleep wont initiate and the lowest clock speed would be 475mhz 370mhz, its as if somethings hanging up the system, not allowing it to initiate lower more battery friendly settings
At the time i was using virtuous prime with motleys kernel with the script specific for virtuous prime, that combination was not allowing lower clock speeds at all regardless what i closed or even a reboot, im now in the process of reinstalling virtuous prime with stock kernel as vanilla as i can make it, as a base rom with all my apps ready, and it seems to be doing what its suppose to be doing, CPU wise.
Gonna get the rom just the way i like it and nand backup, before i reinstall motleys kernel again to see if it improves the battery with its under volt features, this time im gonna wipe davlak and cache see if that makes a difference
Im constantly using eco mode, so thanks for that observation, will definitely keep that in mind when im testing
Sent from my Transformer Prime TF201 using XDA
Yep, what I do almost every day is reset CPU Spy stats when disconnecting my tab from the power so I can have an accurate read of the whole day.
Deep sleep working, CPU scales down to 102MHz like it should.
WiFi is like a black hole of energy when transferring data hehe, wifi on with only chat client and my email and Widgets synced uses almost no power... downloading anything, web browsing, music streaming eats the battery
My tablet also seems to go into deep sleep just fine (at least a few small tests indicate that it does). I'm having the same results as Zephyrot though, if I'm doing something that uses the data connection much it just hammers the battery. It's odd that I can play GTA III with settings turned all the way up for 3 hours and have it use less power than lightly browsing the web for an hour. Do you guys have C3 or C2 models ? I'm curious if the changes they made might have some influence on this problem.

For reference im on C2, but im in the phase of testing some roms and kernels(recently unlocked to try Cornerstone Rom) so my testing results are gonna be all over the place until i find the best performance/battery rom and kernel, untill then im gonna be doing basic short term tests, untill i settle down, so as far as my personal findings are concerned, take em with a grain of salt

Exactly my experience, Asphalt 6HD uses less battery than wifi!
C20 Prime here.
Since .21 update my battery life is crap! I can have fully charged tablet and dock, leave it overnight and next morning dock is completely drained and tablet has lost 5-10%. I thought it was wifi issue at first, but have tried several times in airplane mode and still have same result. After reading this, I will try cpuspy and see if it is a deep sleep issue. I cannot tell you how much I regret "upgrading" to .21, which I did accidentally and lost root in the process. Man, I wish this device had a do-over button!
Hi everyone
So I recently got a S2, upgraded it from stock Gingerbread to stock ICS via Kies, then flashed CM9. CM9 was great, but I quickly noticed worse battery drain than that of GB. I sorted out all wakelocks, now facebook is the top one in better battery stats list and it's only 10mins in a day so I don't think that's a problem. When charging, vbus_present shows up and keeps the phone from sleeping, but that's a normal thing when the phone is plugged, right? CPUspy shows the phone is in deep sleep the majority of time I don't use it, so I assume I have no wakelock problem.
But even then, the battery still seems a bit bad. When in deep sleep with wifi and mobile data off, it would lose around 1.5% per hour; and with moderate/high use (internet with wifi or gaming), I'd be lucky to have it last 3 hours. Charging to 100% from zero takes about 3 hours.
I also tried recalibrating the battery through BC, but haven't noticed too much of a difference.
Recently I found a guide on disabling fast dormancy via the build.prop file. Still waiting for results though.
So, my questions
1, My battery usage seems normal, doesn't it? 1.5% per deep sleep hour is acceptable I guess, but 3 hours of usage seems a bit short. Too short.
2, What effects does fast dormancy have?
1) Totally unacceptable. Mine lasts at least 7-8 hours with high use..
Does your phone heat up while the heavy use ???
What brightness level do you use for the display ???
How many apps do you have that can gain internet access ???
2) By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.
Luckily, Fast Dormancy can be disabled on the phone. For the Galaxy S II, do the following:
Dial *#9900#
Press “Disable Fast Dormancy“
Press “Exit“.
Easy as that!
Thanks for the suggestion I have brightness manual and at around 20%. Wifi is disabled when not used, and mobile data is always turned off unless I need it, so basically apps only get internet access when I want them to. I have also disabled sync for both google and facebook, but fb still pushes notifications to me while it's connected. Is that a major battery drain, and if yes, how to disable it?
Anyways, facebook, instagram, youtube are the only apps than can access the internet. No messengers or anything that may keep a wakelock.
My phone doesn't heat up during normal use, maybe a bit when I do some gaming (Max Payne?)
Also, *#9900# doesn't do anything on my phone. It doesn't bring up a menu or anything like that.
Bump. Guys?

Install BetterBatteryStats (search for it on here/Google Play), might help you nail what's causing the drain.
Yes I did, as said in my original post. After a night the highest wakelock are just around 10 minutes, and that one was facebook. Uninstalling it however had no effect.
Delivered using Nyan Cat's rainbow powers.
Thinking logically, there's got to be something else in those stats (partial wakelocks in particular) that's causing that drain. There's no way having fast dormancy enabled/disabled is either going to cause/fix the drain you've mentioned getting '3 hours of usage'; (I can get 5 & a bit hours screen on with CM9 & variable usage/mostly 'moderate' use) given everything else you say you've tried.
Post BBS logs here if you want someone to have a look.
Edit to add - Also post a screenshot of the 2nd screen in settings/battery, the one that has history 'details' at the top, with the 'mobile network signal' bar underneath the main battery graph.
Here you go: pastebin.com/1UwicChJ
I just registered half a day ago and don't have enough posts yet to paste links, so sorry the phone was only on battery for nearly 2 hours with some light browsing and facebook, but I hope it works.
Anyway, I looked through my running processes, and dsp manager is the only non-OS process running, besides facebook. I got CM9 so it came by default. Could dspmanager be the culprit?
Delivered using Nyan Cat's rainbow powers.
It's a new phone he's got there and I doubt it could be anything battery related itself.
I'm using CM9 nightlies and I get around 9 hours moderate use. It has been said though that a lot of these CM9 builds have battery drain and heat issues.
I use Juicedefender to help with the battery life which seems to work.

About 1/3 of this time was on wifi browsing. The drop is much more drastic if I play games.

A couple of observations. There's nothing that stands right out in the BBS log. The other one is, looking at that graph you've lost ~15% over a bit under 2 hrs. The screen has been on most of the time the phone has been awake (confirmed by the BBS log) if you look at the respective bars. You've also been using WiFi for most of the time the screen has been on/phone has been awake.
Roughly speaking, going by the screenshot, you'd get ~5hrs+/- screen on time if you kept using the phone in the same way you had during that just under 2 hrs, and this is pretty much normal. I haven't had drain issues for ages, so I double checked my details on the 2nd screen of settings/battery to make sure CM9 is reporting these details accurately (screenshot attached). Certainly in my case, this screenshot reflects what my phone had been doing for the just under 5 hrs it had been off charge/since last reboot; that is, >90% of the time in idle/deep sleep. So it probably isn't CM9 reporting these details inaccurately in your case either.
The BBS log & screenshot don't illustrate the problem you talked about in your OP. Now, if I had to take a stab in the dark at what's causing problems when you do have them (and FWIW, I do believe you're having the problems you mentioned in your OP at times), in the absence of any other info, maybe your WiFi router is constantly sending the phone packets (what's been referred to as a 'dirty router' on here before) when you're connected to WiFi & not actually using it. This scenario has been known to cause relatively high levels of drain.
So to be honest with you, based on that screenshot & the BBS log, I'm not really seeing a problem.
Now, if you want to post the same again when you actually have a problem with drain similar to what you described in your OP, happy to have a look at them. But for that ~2hrs covered by the BBS log & screenshot you posted, that's pretty much normal.

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD
Nah. Anything with screen on is far from 'light activity'. Screen consumes far & away the most juice. In saying that, I've seen some people on here say they can get 8-9 hrs screen on with 2000mAh battery. How they do it I have absolutely no idea.
But if yeah, 5 hrs with the screen on most of the time whether browsing or playing games (games in particular are very CPU/GPU intensive & thus use a lot of zzzzs; unless they're really basic games like chess or similar), or anything else isn't too bad. Can you do better ? Obviously, if people say they can get 8-9 hrs. But it's not a matter of doing A, B & C and you'll magically end up with massive screen on times. Every phone is setup & used differently, and getting the absolute max out of every charge takes a lot of trial & error and experimenting with settings/setup.
There are tons of threads about the subject on here if you feel like going down that path. For me, I'm happy with the battery life I get these days because you can really obsess over it & spend a lot of time stressing over it/trying to maximise it for often very little gain. I'd rather simply use my phone a lot during the day & charge it at night.
Yeah Crackberries are like Japanese cars, they can run on fumes pretty much ;-) Having a dual core processor, a decent GPU & a huge screen kinda changes things.
There is one thing you can do fairly easily tho. And that's to make sure the phone spends as much time as possible in deep sleep when you're not using it. That will ensure that you have enough juice to get you by when you do want to use it. Simple ways to help achieve that is to turn off data/WiFi completely when you're not using it (tho many people don't like to do this for different reasons; which is perfectly OK if you're happy to live with the resultant drain), and make sure you've got no apps that are doing things they shouldn't be doing (like syncing, for example) while the phone should be sleeping. Again, there are lots of threads about same if you ever feel like a bit of light reading ;-)
So yeah, if you do find you experience drain that's not normal/outside the usual pattern you have, definitely post details & people can have a look for you. And as you said, you'll get to know what really is normal with regard to drain & so on is as you use the phone more (I tended to use it constantly for that first couple of weeks as well).

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD

Already took such measures. Wakelocks killed my battery over my first night with the phone, and I woke up after 7 hours to find a ~50% battery completely empty. Now things are alright, I clear CPUSpy stats before I sleep and wake up to around 95% of deep sleep time. Overnight drain varies between 5 and 10%.
And yes, yes you are right. Maybe I should stop going nuts. I'm checking BBS and CPUSpy every hour, reading every XDA thread on battery, and calculating my battery drainage every morning I wake up :laugh::laugh::laugh:
Re: dirty/'noisy' WiFi networks, have a look at this post as an example of what I was talking about above.

Umm...so I just woke up, and noticed a wakelock in the kernel category. It was PowerManagerService, and it occupied around half an hour. Overnight, aftet I've slept 10 hours (got a day off ), my battery came from 24% down to 13%. That's a rate of roughly 1% per hour. Is that normal? And also, what is that PowetManagerService wakelock?

Fantastic. Looks like you got your 10 posts That tip is about as useful as "don't plant cauliflowers in concrete".

Because Im seriously curious... This phone has a rap of being "atrocious" in terms of battery life... Now I'm not making this post to be mean or anything, In fact I really do want to know what IS causing it or some theories.. and share one theory I have
But my personal experience really says otherwise, Tonight I set a new "record" on my One X+, 16 hours 28 minutes with 2 hours 43 minutes screen on time... And I didnt do anything "extreme" to achieve it, My Google Now is on, my location services are on, autosync is enabled.. About the only thing I have done is install JuiceDefender (My previous record without Juice Defender was about 15-something hours) I watched youtube videos, Read some websites, listened to music, and even played some games... I'm completely stock, no roms or anything
Now, I will note, I had a problem the other day where my battery killed itself, FAST.. After a bit of digging around and tweaking, I discovered the cause was that my One X+ wasnt entering Deep Sleep, and thus the processor was staying at 475mhz or so even when the screen was locked (Causing the battery to be drained like i was using it) What caused this? My Wi-Fi, of all things, While I had a really good signal, I had it prioritizing the 5.8ghz radio, and in my room, the 5.8ghz signal is fairly weak as im a ways from my router... so the phone was switching between it and the 2.4ghz signal, causing the phone to be unable to sleep, Removing the 5.8ghz AP from my phone fixed the issue completely and my phone returned to "normal" behavior...
Yeah i know it sounds really farfetched and weird, and took me a bit of googling to get the idea that this might be what was causing my issue (I tested my hypothesis by turning Wi-Fi off completely and using Cell data, Sure enough my phone slept like a baby and barely used any battery.. i flipped Wi-Fi on and suddenly the phone was drinking its battery down rapidly.. I disabled the 5.8ghz AP and suddenly the phone worked 100% properly again)
I suspect that this is the cause behind some folks who are saying their phone is draining down 7% in 20 minutes with it locked, Its simply not entering deep sleep, the processor is doing something in the background... Could some of them be having the problem i just described? Its possible, Especially if you have multiple Wi-Fi points in your house.. Could the wi-fi in the One X+ be bugged? I dunno, Thats possible to, Thats why I'm posting this...
Now of course some people need a phone that is going to go for 2-3 days without a charge, and no, this isnt the phone for you (There arent many smartphones out there that can manage that if you actually USE it any) But really.. 16 hours with 3 hours of screen on time is pretty darn good.. Thats getting quite close to my Galaxy Nexus with a 3500mah Extended Battery (Around 18h standby, 3.5-4 hours screen on) despite all of the "handicaps" the One X+ has over the simple GNex (Like LTE and a Quad Core processor) and is vastly better than my stock Galaxy Nexus battery which died constantly...
And yes, heres a screenshot as proof if you dont believe me...
I just want to add that I find that googlenow also drains the battery and as such I always disable it. It was a problem on my S2 and thus I have disabled it on my HOX+
Honestly, mine wasn't lasting longer than 8 hours until I rooted it and simply "froze" all of the AT&T apps I wasn't using. That alone gave me an extra 2-3 hours a day of battery life! (I've read here that the AT&T apps, even if you aren't using them, keep running in the background) The other thing that seems to help is an app called Smart WiFi toggler that's done wonders for both myself and everyone else I know who uses it in terms of minimizing WiFi battery usage.

I'm sure other folks have other tips, but this has been the winning combo for me.
I should add that i also froze every ATT app i could and never opened ANY of them.. So maybe thats part of it as well..
JuiceDefender i believe is doing something similar for me with the Wi-Fi by turning it off when its not needed...
My battery life was terrible when I first got this phone. I let it charge out completely once this month and I've been using LBE Security Master. Those two things have greatly extended my battery so much I have been able to go more than a day with it before charging. Another factor might be that my phone isn't carrier branded or anything.
The "My Wi-Fi isnt letting my phone enter deep sleep" thing is actually starting to get annoying, I thought i fixed it but it keeps coming back...and yes, it is legitimately killing my battery at twice the normal rate because the phone will -not- enter deep sleep
My phone goes into deep sleep just fine if i turn Wi-Fi off...and my battery drain returns to normal....So it cant be some app downloading stuff or constantly pinging the internet or else it would do the same thing when im on LTE...
Also i've reset the "Keep Wi-Fi on during sleep" option to never 20 times now, it keeps going back to "always" on me...
Ideas?
My battery life is ok. See here:

Mine is too, Provided i turn Wi-Fi off or i get the bug to go away for a bit (basically toggling wi-fi on and off a few times and twiddling with the settings makes it work right, but the problem comes back minutes or hours later)
Otherwise, Wi-Fi wont let my phone enter deep sleep, and my battery drains like im using it..
The thing thats annoying me more is that the "Keep Wi-Fi on during sleep" setting will not stay where i set it and keeps going back to the default setting....
I guess i can just toggle wi-fi on and off manually...
