Desire battery observations

I know you guys might be tired of these threads but I thought I might as well post this.
My desire is fairly new(Less than a week) and so far its been good apart from(What I though) battery life. i've been trying to improve it and I think I might have "some" progress.
Currently I'm running DeFrost 4.9 with HAVS @ 1137(4.9a) kernel with the very latest radio, I also use only 2G networks(No 3G here). I got two Gmail accounts but only one has sync(The other one is merely for Google checkout CC purchases), I got one Facebook account set to sync every hour as well as LP Facebook widget also set to sync every hour. I also got FancyWidget syncing weather every 3 hours. Apart from these I got Nimbuzz running 24/7 in background. The battery is calibrated and yesterday I did a complete discharge/recharge.
Now I plugged it off the charger 2 hours ago, it was at 100 according to spare parts. The brightness is at 2%. I did some lite browsing, browsed a bit with Tapatalk Pro and 40 minutes ago went to a market nearby. During my trip to market I had Google Navigation turned on navigating me(During both, the trip to the market and return). Now while making this post the battery is at 81%. Does it sound right?

How much time the display was on? How much time was the GPS on?

Be careful, don't be happy before time. I did the recalibration too, and found that my phone would turn itself off at ~20% remaining battery.

During the navigation, about 5 minutes for display, 40 minutes GPS during which I went into a building for 10 minutes and it probably lost signal then.

OK, this ain't good. I slept at around 2 AM with 29% battery life. In the morning(10:30 AM) it was dead(0% battery).

Sound about right. 8.5 hours with your facebook and other syncs. I don't see any problems at all. Mine does this too.

First, in the night put the phone in airplane mode (I dont think u need to check ur facebook )
Second, check if u have useless programs that are using cpu in background, if is this the case UNINSTALL that program and CONTACT the developer. We dont need to kill those kinds of app, we just have to UNINSTALL if an app doesn't work properly, untill the developer will fix it. If all people will do like me, the market will full of great apps

I don't think I have any useless stuff running in the background. All I got are 2 widgets(Facebook and Twitter) syncing every 1 hour and 3 hours respectively, one Fancy Widget fetching weather and Gmail push for one account. Is their a way I can check all the services running in the BG?
EDIT : Forgot to mention Nimbuzz running 24/7.

I won't rehash all of what has been heavily discussed by now in much greater depth, like in the FroYo Battery Usage thread. But auto sync with such social applications and you set yourself up for low battery runtime to begin with. Especially with a constant polling IM and/or battery widget running too. Don't expect much.
Anyway, I don't use them but weather, stocks, 5 mail accounts and news is set to auto-sync every 15 minutes and WiFi is always running if available. Last discharge as soon as I connected charger ended at:
http://bit.ly/c6R59G
http://bit.ly/bmM9oN
http://bit.ly/cMlnun
http://bit.ly/akPvr7
I slept twice for 7-8 hours each on that charge and it includes all of my daily usage including listening to 127 minutes of MP3 via headphones with the screen off.

Hmm Wi-Fi + Nimbuzz really screws up the battery . Last night I turned off the Wi-Fi and slept for 8 hours. I had 46% battery before and in the morning I had 40%. I also have disabled Auto-sync for Twitter/Facebook widget and Facebook app. Now the only running services I got are Gmail push, FancyWidget weather and Nimbuzz.

How did you manage to get such good battery life? Your phone lasted for over a 32 hours period which included 6 hours of display. And that too with stocks and News syncing every 15 minutes. Does Nimbuzz really screw you that much?

Well now datz some good battery. Which ROM are you using? Which Radio are you using?
I don't have any account/social networking syncing. Don't use wifi more than 20 mins a day. Brightness 20%. NO GPS. No Bluetooth. No stupid application sucking battery's power. If my screen is off I lose about 3-4% for a period of 5 hours, so no app sucking the battery in the sleep mode.
If i use EDGE when the battery is Full for about an hour I get battery drain of 20%
Would love to know more details on which ROM, Radio and your settings.

OK. There's not much I can say except what other guys who know better than me said here http://forum.xda-developers.com/showthread.php?t=743172
It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

In contrast, I lose 1-2% over 8-10hours in standby, maximum, with WiFi on. Usually 1%.

Thats some damn battery life you have there. You are on a Sense ROM? Do you actually use Sense? If so you're either exaggerating or I'm a total fool(I'd prefer the latter).
I've been trying to fine tune the battery, currently I'm using DeFroST 4.9 with SVS 998Mhz @ 1275mv kernel with 17_2 radio. Re-calibrated the battery yesterday and compiled a custom wi-fi module containing fixes for sleep disconnection today morning.
I left it at night around 3 AM with 99% battery, turned off the Wi-Fi/EDGE but kept mobile on. In the morning(Around 9:30AM) I was at around 91%. Gave it a quick charge to 100 till around 11:15 AM. Disconnected it and from 11:20 to about 11:40/45 AM I had quite a heavy chat session over Nimbuzz with my friend. My battery went from 100 to 94% in that time. After that I pretty much left it, picked it up to check a mail once or twice and sent a few messages over Nimbuzz. It is 1:40AM now and I'm down to 89%. All of this was over Wi-Fi, GPS off, Bluetooth off, no tethering no nothing. I got no Facebook/Twitter auto-sync. Only FancyWidget(every 3 hours) and Gmail Push. Brightness is at 2%(Although even then it is a bit bright, maybe it is just me).
I am using Extended control widget to see the power percentage.

Whoa ! Amazing post there. This should keep me occupied for quite some time to figure out what the heck is going on with my battery. The battery life what you are getting is really good and that is what everybody should get provided they figure out what the heck is sucking their battery that bad. Lotsa things and apps you have said drains the battery is on my phone and I haven't even started looking at logs in detail. Itz been only couple of weeks since I have this phone so I'll defn start looking into this issue.
Few questions
1. What issues did you have with your build.prop?
2. What battery widget are your currently using ?
3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ? Would be great if you could link us to the location mod

OK, It is 7:05 PM now and I am down to 70%. Nimbuzz was on all the time along with Wi-Fi(Although I don't know what happened but it switched to EDGE as if it lost Wi-Fi connectivity, Wi-Fi wasn't disabled, just disconnected). And I pretty much haven't touched it since 1:40 PM. Not as good as I hoped, but still kind of decent.
And my Wi-Fi strength isn't that great either, it is either 1 or 2 bar out of 4.

Well, I haven't done any such kernel modifications intentionally. Never had any need to either. 14.5h since last charge now, cell on 5h, WiFi on 12.5h, display on 2h and 76% remaining (actually, those stats were collected and written an hour back). The Desire display has been verified to consume at least 70% of the total device power when the screen is on. So you can't get more hours with display on if it didn't run as such.
It's HTCs ROM so of course it is using Sense. I can't do without most HTC added goods in Sense. Let alone the Mail, Bookmarks, Calendar, Stocks, Copy/Paste, Lookup, Clock, Gallery and Camera apps and widgets. The widgets I depend on work well only on the HTC ROMs I've tried. The missed Sense goodness combined with the bugs and problems I had on AOSP ROMs were extremely problematic so I moved back. Even my video recording and native playback is much better on this ROM.
To be frank, you've hardly had the phone so you'll learn much more yet. And it comes through search->reading->experimenting first. 1-2 weeks is too little for even figuring out most of the basics, unless you're moving from a similar phone and OS. For one, you'll need to actually read the linked thread to see what many observed and experienced. It took me and many others 6 months to learn things and get to this stage. Every other day I was testing and monitoring. But be aware that you can't, for instance, have the exact same setup and usage as me to have the same resultant battery life.
Had you read the linked thread you'd also be aware by now that bugs were filed for inaccurate % readings by Androids Battery Usage section. However, its time tracking was reliable in my testing.
- On your typical full discharge, how much time and % is listed under Display on?
- And for cell?
- Which A2SD are you using?
- Static wallpaper/color?
- Animation settings?
- Location on?
- Network location errors in logcat?
- Cell network chosen auto or manual?
- Did you mention all the widgets on all homescreens?
- OSMonitor/CurrentWidget values in idle screen on and idle screen off?
I use EC and SwitchPro widgets too but their battery widgets (like you mentioned) are known as ones with high consistent drain. The EC dev also corroborated this in its thread under the Themes section.
The 'idle' drops you get don't make sense to me unless there's fundamental hardware/software activity you haven't properly monitored and logged. Even kernel and I/O usage in the background. You'd be surprised at the difference one buggy underlying feature can make.

- HTC Desire via XDA App -

If you're actually asking those questions, here goes. Note, I am at 66% and the time is 8:56PM. And after this I'm gonna nandroid this ROM and try SuperVillainHD just for the kicks. Also, can it be that since the phone is relatively new, the battery is not up to its full potential?
Q1, 2) Battery usage is :
Display: 35% (35m 37s)
Wi-Fi: 20% (9h 44m 22s)
Cell standby : 15% (9h 44m 22s)
Phone idle: 14% (9h 9m 42s)
Android system: 6% (CPU Total: 9m 35s, CPU Foreground: 27s, Data sent: 7.82KB, Date received: 11.38KB)
Nimbuzz: 4% (CPU Total: 6m 46s, CPU Foreground: 2m 54s, Data sent: 298KB, Data received: 851KB)
Android OS: 3% (4m 1s)
Voice calls: 2% (45s)
Q3) I'm using DeFroST ROM with A2SD+
Q4) Yes, I'm using a static wallpaper
Q5) Animations is set to : All animations
Q6) GPS is disabled, if that is what you mean.
Q7) How can I check this and what would it show?
Q8) Didn't touch this, so I'm presuming Auto.
Q9) I'm not sure, so here goes. I got a Twitter widget, Facebook widget, both are set for manual syncing. Got FancyWidget syncing every 3 hours and several harmless icons. I got 3 bars of Extended Control widget and a google search widget
Q10) I don't have those, are they available in market? Do they consume battery?

I'll have to open the file for that to check exactly the changes I made. I didn't really follow anyone, just went off my own understanding and intuition. If I try to access the dir or open the file whilst the phone is not in Recovery, it'll force a reboot so I'll give more details later on this when I'm near a PC.

FroYos A2SD was nice but I needed much more space and was trying A2SD+ with various ROMs as well as manual use on HTC ROMs. Endless problems such as very remarked, consistent sluggishness in basic functioning, total boot and app load slowness, including high, persistent background CPU and IO loads and very poor SD card transfers over USB and WiFi made me sack it. I lost a class 4 16GB Kingston SD card with errors inside 2 months. I transfer 2-4GB in/out daily and many transfers started failing. Widgets bugged out frequently when you needed them most and had to be all re-setup. Video record and playback became dis-able. The phone became useless except as a toy. That's not what I bought it for but as a helpful companion. I eliminated everything in question. It was simply the SD card [over]use compared to internal memory.

Even though I used this, I still have select applications not on the SD card upon learning that they worked far more consistently and properly with lower power and CPU usage when using internal memory. Trial, observant monitoring, and error.

If you get great battery life, please share your tips here!

I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.

Best tip is to stay on wifi as much as possible. I got 3 days on wifi and about 4 hours use.

Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too

get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.

I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.

I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.

I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off

So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...

Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).

Tips and tricks: improve JB idle battery life.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.

Thanks for the tip

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.

I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.

Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings

I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.

Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

Also even though you are disabling sone of these apps like google now.... you can still use it your just turning off the background nonsense

Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that

I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.

Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.

(To save time, I'm cutting & pasting my post from another similar thread.)

"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,

I noticed the huge difference as well. I was walking around Chicago yesterday and not using my phone. After 4 hours I looked and my battery was at 50 %.

My personal experience improving battery life. (+GUIDE+PICS)

Hi,
I have been trying how to run the phone with one charge per day.
The first thing I did was getting the original OEM Extended Battery (2000mAh), in fact it improved my battery life around 20%, but anyway after that I needed a little more. The phone feels better, more "stock" than with the 1750mAh
I checked my battery stats and saw that Google Services was draining my battery, sadly I tried disabling Google Now and Location Services and the drain is GONE. It might be very radical, but where I live Google Now almost works only like Voice Search. You could add a shortcut so that you can enable Location Services when you need it (Using Maps for example)
I am running latest CM10.1 nightly with Franco's kernel 372, it works fine, the only change I have made is the min frequency which is 192mhz, I don't see/feel any lag (I ran ANTUTU and I get around 8200-8500), I haven't done a clean flash for CM10.1 since January since I use Cyandelta (I'll have to do that and it might help too). Another thing I did was editing autobrighness level, stock autolevels are too high when I am in dark places, you do that in brightness under screen. I lowered the ones under 300lx. For outside it makes no sense lower the brightness (You won't see anything hehe).
After that I was getting better battery life, but then I installed https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=es (Greenify) what a wonderful app. I set to hibernate: Calendar, Chrome, Dropbox, CamscannerClean Master, CyanDelta, Instagram, Maps, Path, Shazam, Twitter, Xda and Youtube. I still get my emails, my whatsapps and everything seems ok. You could be less aggressive than me, but hibernating Chrome, Maps, Path and Shazam is a must in my opinion. If you open the apps it works just fine!
What else?
I created a Tasker profile and it turns on autosync each hour from 4am to 11pm for 1minute. It works fine, as I don't really need to receive push emails (I think that's the only thing that Sync does). I have to test this because I think that if I don't use tasker and leave autosync on always it might be almost the same drain.
These are my results:
You can try these tips and let us know your results.

CM 10.1 nightlies and AK kernel latest. None of your tweaks.
Personally disabling and setting all those things up you did seems overkill and defeating smartphone purpose. Are you really away from a charger for 15 hours at a time? You disable sync but then install tasker just to turn it on once an hour at night? Why? You just killed one service but introduced another.

The important information in your screenshot is the screen on time, I could reach 17 hours at 50% with 1 hour or 1:20 of screen on..
I am reaching around 4 h of screen of time which I think is very good.
In my case sync only works for getting my Gmail emails, checking it every 1 hour is ok to me.

[Q] Short battery life but nothing specific seems to be a big drainer

Hi guys,
Though I have been reading these threads for quite some time now, I just joined so that I can post the issue that I am facing.
I am rooted and using Liquidsmooth v2.4
I am facing a battery issue. Battery life is short. I never survived more than 2 hours of screen time on my device which I know from these forums that is not normal.
The stuff I have tried but didn't help:
Wiped and factory reset on several occasions, both using the settings function and CWM
Flashed various roms (Cyanogen Mod, Carbon, Liquidsmooth, Stock rom)
Unroot to stock and root again
Changed to various more battery friendly CPU governors
Changed battery with a friend who is using the international version (which is using the same battery according to the Samsung website)
I am not in the states now and the local Samsung service centre refused to service it because they don't have the appropriate parts and also due to the difference in software. (I unrooted it and restored to stock before sending in.) They just looked at the model number and refused service; didn't do anything more.
I have attached some screenshots. There are no obvious wakelock issues and no app in particular is draining the battery. 50% power used on screen appears to be normal. The rest of the apps also look like they are behaving themselves, at least power consumption wise. I am not a very heavy user and don't run any games/apps that are huge in resource requirements. Email/facebook/browsing are my main activities.
The current settings on my phone:
Auto brightness
Wifi/bluetooth/GPS all off
Autosync is off by default but will use it sparingly if I need to.
Almost all of my apps have their notifications off and all apps are set to sync manually.
I only have one calender widget on my home screen, no others elsewhere.
CPU Governor is "ondemand", iO scheduler is "row". Min/max freqency: 384/1512 MHz
Juicedefender is enabled with "aggressive" (I know its effectiveness is controversial but on my device, disabling it eats more battery)
Any help is appreciated. "Thanks" will be awarded to all who post!
Thank you!

I see horrendous wakelocking. Install BetterBatteryStats. Charge it up for a bit, reboot the phone, then let it idle for a couple hours. Then post screenshots of everything.
It might be the worst I've ever seen. Good news is it's probably not a hardware issue.

It also looks like half the time you had a poor signal. Data transfer on a poor signal can wat at your battery too.
Always use wifi when available.

thanks folks. I've installed better battery stats and will update shots accordingly at the end of the day or end of the battery cycle(probably won't last a day)
Really appreciate the help.

Here are the shots for today.
I rethinked about the poor reception comment and wondered if any of my radios are malfunctioning or if my radios can work in the frequency bands here in Singapore. I called my local service provider to ask about the frequency bands and.it appears that my device's radios can recieve the GSM bands here although they suspect 3G may be an issue. Nothing concrete but I do hope to find out if that could be a possible reason for my battery drain.
I managed to squeeze past 2 hrs of screen time today by using as much wifi as I possibly can. This improvement in battery life probably means that data reception can really be an issue. It's not unlikely that both my home and workplace suffers from.bad reception but i do have a Q. If poor reception is an.issue, will the battery consumption by cell radio sky rocket?

For some reason the previous battery stats screenshots was only for about 5 hrs. i have refreshed and have uploaded the refreshed screenshots

This is not BetterBatteryStats. We already know your battery life blows. I want to know why, and BBS will tell me. I can't do a thing for you until you show me that. I think there is a free version on the forums, but it's cheap in the Play Store, and worth it. Get Greenify, too. You're going to need it. Greenify will prevent notifications from showing up for greenified apps. If you don't need notifications from Facebook (honestly, who does?), Greenify it. Maps, too. And disable Juice Defender for now, so I can see what is really happening.
Poor cell reception, if not on wifi, causes drain, yes. It seems to only get really bad when the phone can't hold a data connection.

Try turning off GPS. Also under Settings > Backup and Reset, turn off the Back Up My Data option.
Additionally, check the stickies in this forum. Woody has a fantastic Battery Thread that you should read if you haven't already.

Once you get a good cycle run with BBS, the screen shots we want to see are Since Unplugged/Process and Since Unplugged/Partial Wakelocks. Those two will help tell what is eating your battery and also what is causing all those wakelocks in your original screen shots.
If you are using Juice Defender, that will contribute to the wakelocks (but doesn't keep your device from entering Deep Sleep, so no worries there). I use it, but I have mine set up custom plus have done some basic build.prop edits regarding the RILs and wifi_supplicant_intervals.
My suspicion is that there is a rogue app that is transmitting data somewhere and that is not letting you sleep. If it is transmitting in a poor reception area then that puts ever more strain of things. You are not the first and wont be the last but Doc, Aero and I can help you figure it out.

Images for today. I've included a few more shots for the items that appear lower in the lists.
I've installed greenify but did not add any apps while collecting these data. Juicedefender is also disabled. My screen time was less than 2 hrs.
I did some of the stuff listed in Woody's informative thread. Deleting the tombstone files, lost&found files etc.
Thanks for everyone's help. Hope to solve this issue soon.

Looks like Maps is misbehaving. Terrible coding is terrible.

Yup. Looks like you are broadcasting your location all over the place. Do you use Maps? If not close it and Greenify it.
Are you getting notifications from Facebook or have a "Check-in" thing going on?

Edit: Tombstones and Lost.dir files are just memory management and have nothing to do with battery.

Shots for today. Things are a little better but looking at my screen usage, maybe there's still a lot of room for improvement.
I've greenified just about all apps that may run in the background. Facebook, Maps, Google+, Gmail, Chrome, Google Search (I converted it into user app), dropbox, etc. Whatsapp, Viber and Wechat are spared as I needed them to be able to notify incoming messages. Juicedefender is on, with advanced settings - set to sync only once an hour. Maps have been set not to update my location although I didn't go to the extent of denying location access ( I use maps fairly often).
All these are rather aggressive steps and I do see improvement. What else can be done? Other than my messengers, all my notifications are essentially off.
Once again, thank you everyone for your time and effort.

Please stop using Juice Defender. I want to see what your battery life looks like without it now. And it's also responsible for the majority of your wakelocks. And if you could get us some ~4 hour idle BBS stats (during sleepy time), that would be fantastic.

Noted. I'll charge my phone up and take some shots in the morning. Juicedefender will be disabled and hopefully more information will be revealed. Do today's shots show any improvement?

I think you are heading in the right direction (8% deep sleep improvement). For this next test, please disable Juice Defender (don't turn it off through the app, but disable it in the app manager to make sure it can't run). Also, I'm hoping to get a test where the screen isn't on for more than a couple seconds, so I can get an accurate reading on the usage per hour.
I suspect the rest of your issues (bam_dmux_wakelock), are due to a bad cell connection for a good chunk of the time. Connecting to a wifi network will solve that. If you don't have a wifi network, you can turn on airplane mode, or set up some Tasker profiles to help with that.

Out of curiosity, how bright do you have your screen set? Obviously its a big drainer, but it seems like every time your screen is on the batt level plummets.
