(Question) juice defender

Does anyone know if juice defender is actually a good app or no.
I use it on my phone but I never keep and data connections on anyway 3g 4g and wifi r always off unless I need to use them and then I turn them off when I'm done.
Since its "job" is kind of already done by me could it be a source of battery drain since its always running andin a way its for no reason.

I know one of our devs randomking doesn't like it, and since his roms are heavily battery life oriented it was enough for me to stop using it

Just think.its another app that wl run.just go to settings and customize that way.task killers waste battery and take up space.to maximize battery,research and try roms and kernels with different settings.im on miui rom,kernel v8,panache radio,and am at 38% battery,so with moderate use,its 38% after 10 hrs.gps off,with sporadic use of wifi.in otherwords,try different setups,but juice defender is up to u.

That's what I was thinking.
So you also think that advance task killer isn't nesessary?
I use my phone a lot for almost everything so I try to keep my battery as high as possble but sometimes after just 3 or 4 hours I could be at 30% or lower.

It is a very useful app, it will disable your radios when the screen is off to preserve battery life.

But I keep everything off already
And I usually have problems with my signal I'm not sure if it could be from it or not but I'm gonna just uninstall it for a whil and see if there's any differences.

Juice defender works well for me. At work I would have to put my phone on the charge at noon just playing mp3s. i get through the hole day now with 40% or better. i stream music for about 7.5 hours of the work day.

I've used Juice Defender since I got my Epic.
Though now that I'm running an EH17 ROM, and frozen DRM services, it's really not necessary for me anymore. Been off the charger for 11 hours with light use and it's still over 50% - on the rom it shipped with I was lucky to get 8 hours before it would shut off (with JD I'd get about 18 hours).

It probably helps you cuz you have internet connection on and it turns it off when your phone is sleep. I keep all my internet connections off all the time so I don't think out does anything in my case.

I'm on eh17 too and I froze drm, sns, and system updates. So far I've been on my phone for an hour and a half and in still at 100% this is great. I installed juice defender last night.

I have been using juice defender for a few weeks and it helps my battery life a lot. It really depends on your usage. I am in roaming areas fairly often where my phone used to search for signal for a long time if I keep it on.

I installed Juice Defender the other day & my phone had issues right away. I unistalled within a couple of hours. However, afterwards I was unable to access my pictures or videos stored on the SD card. I know this app caused the issue because I was looking at some pics right before installing it & could not access them after installing. Luckily I ran accross a post in th PA CM10 thread that gave me the solution. For some reason the Juice Defender app placed a .nomedia file on the root of my SD card that was causing my issue. I deleated that file & the media scanner autmatically started running. Just like that I had pictures again.
I hope this helps anyone that may run across this issue.

It wasn't juice defender... if you have rom manager it was that... I use juice defender and have never had it place a .nomedia anywhere... the app doesn't place files anywhere...

Thanks for the correction.....I assumed that since installing JD was the only thing that had changed in the hour or two that the issue popped up, then that would be the cause.....I have had ROM Manager & GooManager for a while but have had no such issues before....I guess if it becomes an issue then I will have to loose those......I only use them to check for updates & always do manual downloads & installs for the ROM's anyway......
Thanks again & sorry for jumping to conclusions......

Your good... a recent update to rom manager messed some things up... if you check its all over the forums that everybodies media is disappearing... rom manager is to blame... but I believe it has been updated and fixed....

depends on the ROM

I find it depends on the ROM. I was using it for CM9 to help but I find the CM10 pre+kernel+nexus modem combo is doing me wonders. I also stopped using the facebook app, uninstalled facebook mgr as well and use Trillian to connect to FB, AIM, etc. also trying to get rid of this media server.. seems I dont need it. I expect more battery after that (if removing it is possible) because it's #3 on my batt draining list right now.

If you listen to music and such (I believe whether it be streaming or mp3s from the sd card) that's why you see media server so high... same for me, but I'm constantly sitening to music while surfing xda... and still pull off 16+ hours on cm10... I used to use juice defender, but found if your gonna turn of data and such, it saves more battery if you can remember to do it yourself instead of having an app use resources to do so.........

I used to use apps like JD or advanced task killer to kill background processes and turn stuff off until I found out how Android handles programs in the background so I became less concerned.
If you're having issues with massive drain on battery life, make sure its not because of weak cell phone reception. If you're in an area with little to no signal your phone will use up extra juice to try to attain a connection so it'll drain your battery like 50% faster. Also make sure you have things you don't use turned off... like BT, GPS, WIFI, 4G anything thats optional.
Also consider the battery and whether or not it needs replacement. I got a defective battery and didn't know it until I had the ability to compare my phone to 4 other Epic 4g phones.

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.

I turn data off when im not using the internet and when I'm just listening to musc I just put my phone in airplane mode

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).

Fixing battery drain on your s3

I have done pretty extensive testing in the last few days and this is what I found.
TOUCHWIZZ USERS ONLY, uninstall and delete data for the app my uploads. It syncs your gallery with picasa and uses a load ofdata and battery. It won't break anything. turn off instant upload in Google+. Turn off smart stay and motion actions. they use about every sensor in your phone. Turn off the wake up phrase in s-voice. If its on it is always listening for that phrase. I'll keep looking for other things but I got fairly good battery life just doing those things right there.
When uninstalling an app, wipe cache and data first. This will clear any background processes that could stay after the app is gone.
Install es task manager and kill everything you don't need to run on startup to preserve boot time/battery usage. Also it will keep the processors a lot lower.
All accelerometer and other hardware functions use a significant portion of your battery. If you don't use landscape mode turn auto rotate off because it uses that precious battery life.
Weather bar in notification drop down and on your lockscreen will destroy your battery life. Weather widgets also use quite a bit of battery.
Facebook app also kills your battery because its always connected to the internet. Syncing Facebook account to your phone further wears down your battery. Any game or other app that connects to facebook will also do the same.
Look in data usage under settings. Anything on that list uses more battery because its connected to the internet.
If your not in an lte area turn lte mode off because your device will be searching for a signal it will never get.
Low signal strength kills your battery because your phone has to use more energy to hold connection to the network. If you have WiFi at home and bad cell service (or anywhere) use WiFi because its easier it is for your phone to hold good wifi signal than bad cell signal. also turn off your NFC. It uses more battery than Bluetooth does.
Get better battery stats app and look for wake locks because without deep sleep you will never get more than 12 hours battery life.
Widgets, live wallpapers, lock screen ripples and other things that move use battery also. If you don't use it then remove it to save a couple percent a day.
Remember that when charging through a computer USB port or things like that charge a lot slower than an outlet. Slow charging is better than fast charging because your battery stays cooler and that means your batteries total life will be longer.
Finally before you go in a ROM thread and start complaining about battery life, go at least three charge cycles after flashing to optimize your battery.
There are many things that cause battery drain so beware when you download that next app. It could be a battery sucker. If you don't need or don't use an app. Uninstall it because it may have background processes that are using up battery and RAM.

You can uninstall the facebook app, go to facebook on your browser, create a bookmark, and then place a widget on your homescreen for that bookmark. The site is actually faster than the app.

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

ii.Mediaserver. This system process is tricky when it comes to battery. What happens is that whenever you access any sort of media on your external SD card (playing music, gallery, what have you), this process kicks off. Luckily though (but hard to catch), sometimes, this process uses more process time than it should due to corrupted contents on your external SD card. In order to catch this culprit: try clearing your battery stats (for example, restarting your device or coming off AC power), playing some music and/or checking out pictures on your SD card for a few hours. Then, check your processes. If Mediaserver is high up there in usage, you may want to consider cleaning up your SD card. Naturally, we would expect that the process is higher when media contents are in use. I can’t give you a specific guideline such as, "something is up if Mediaserver consumes over 25% battery." This is another example of where you should look up other user stats for system processes based on your specific phone and OS version. If you think your SD card may be corrupted, backup your data, format the device, and slowly, add back files and repeating your media tests. Finding a corrupted file isn’t a guarantee, but this doesn’t hurt if you suspect data corruption.​[/QUOTE]

Turn off GPS when not in need. Turn off WiFi when not near wifi. All the stuff in the op. And undervolted by 100+ mv on every CPU setting. And my phone is absolutely lag free accept when I hit the unlock button it takes like half a second for the screen to come on instead of instantly (160mv undervolted on 192 which is sleep speed I set)

In my opinion maximizing battery life is all about watching out for the things on your phone that you don't care much about but are using a lot of battery life versus keeping the features you like that make your phone a smart phone.
I leave GPS on all the time, use auto brightness, have fb and fb messenger installed, use Google talk all the time, push my work email, etc. and accept the fact that this will cost me about 2% per hour when my phone is idle. I'm also using the latest ktoonsez kernel & task/kt jellybean rom and those help tremendously on battery life (1h45m since unplugging today, 51m of screen time and I'm at 89%). I have definitely been diligent about turning off the things I don't care about, like latitude, location in Facebook, rom weather, etc. and that helps quite a bit. My biggest problem has been maps running for no reason and draining lots of battery, but that sends to be a lot better with the latest rom and kernel.

Maps is known for that. If you don't mind my asking what do you use maps for and could you just use Google now to search locations and it will even give you traffic n stuff. That would probably get you another hour or so a day.

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

what rom and kernel are u using

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 %.

Best battery saver apps for nexus 4

Hi All,
I would like to invite your suggestions on best battery saving apps that you are using and how much difference does it make. Is it worth paying for apps juice defender ultimate or so http://forum.xda-developers.com/images/icons/advanced/battery_full.png
I am on stock (rooted) 4.2.1 and stock rom.
Thanks!

Best battery saver is your self. These apps don't work any better than you doing the things it does manually. If its using resources which they all do to "save" you battery... Its not really saving you battery.. But in fact using it.
Some tips I suggest:
Turn sync off in everything. Go to data usage hit the menu button and uncheck auto sync data. Also you will want to open apps that have notifications and make sure they aren't syncing either.
Remove maps if you don't use it or disable it at the very least this will keep it from polling your location and wake locking the device.
Keep your running apps to a minimum and force stop any unnecessary apps.
Turn off Google backup services. Sometimes this will be pulling and pushing data wake locking the device and using battery. I've never found it necessary especially since I use TiBu anyways for my apps to restore. It never saves my WiFi password either.

This isn't particularly good advice in my opinion. Are there apps that do use battery power when you don't force close them? Yes, sure, but many don't. And those which do without a good reason.. try to find a replacement.
Force closing apps all the time especially on a device with lots of ram will mean that your device has to restart the app completely if you open it again, which takes time and energy.
edit:
Also, turning off sync doesn't really help that much if you still use your apps often but instead refresh manually with the screen on, I'd expect. Of course everyone can decide for themselves, but one of the reasons I own a smartphone is because it can notify of an incoming email or something without me having to go to gmail.com manually. It all very much depends on what you want from your phone and how much you are willing to compromise. Using an App like Lux for example could also save you some battery depending on how bright you need your screen to be etc. There are so many variables to this.

Best battery saver is to not run crappy battery hogging apps like juice defender.
Turn on auto brightness, check your apps and make sure you are not syncing very often unless you need it. For most apps you can turn off auto sync and probably sync manually. I just turn on auto sync for handful of important apps which I open regularly.

Manually turn down screen brightness, don't leave the Wifi or bluetooth on when you're not connected, make sure apps you install aren't keeping the phone awake. Not much else actually works in the real world.

I get two and a half days from my Nexus 4 battery, I can thank Juice Defender Ultimate for a large part of that.
I could do all the tricks that Juice Defender does manually, but it would be a PITA and I'm sure I'd forget some of those tricks.
Better to pay a few quid, take a little time to set up Juice Defender, then sit back and enjoy your doubled battery life.

the best part of Juice Defender was turning off Wifi when not at home.. if you like this feature, search the playstore for 'Y5 Battery Saver'. It does the same thing, is simple and free..
Note: dont backup and restore it in titanium though. If you rebuild, install from the playstore. I have found it doesn't work right if restored

IMO if all you want is bt/wifi to toggle when you aren't home spend $5 on a few nfc stickers and stick one by your front door. You could also go with tasker.
As for battery life, francos kernel is giving me 2 days of battery (far more than I need) with wifi/bt on, whatever apps need to sync do so and I have brightness set to auto.

I found juice defender good for phones that are bloated with crapware and not rooted. It hurt battery life when i used it for phones with custom roms and kernels.

After I turned 'Google location' and NFC off, this thing can easily last the day with average use. Before that it was just draining like crazy.
Sent from my Nexus 4 using xda app-developers app

I've had juice defender ultimate since my Nexus S days. I wouldn't be without it as I can't get my battery to last a full day without it. When it's fully configured correctly, it works fantastic. I especially like that I can configure wifi to turn on and off automatically in areas where I have a saved wifi. I can decide the interval I choose for syncing data, and there are many other features. I'm not going to be manually turning on and off functions all the time, all that does is create more screen on time and is a waste of my time.
Bottom line, for me juice defender ultimate works because I spent time configuring it properly for my usage.

1.5 hrs screen on, 1.5hrs on call...I got close to 6hrs screen on when I did a drain test.
And no, I wasn't getting 2 days out of the phone stock with the same usage, it was more like 12-18hrs.

I tried using Juice Defender on a different phone and all it did was make the phone buggy with problems with wifi connectivity and other minor irritations and I could never configure it in such a way that didn't give me problems.
Are you having trouble making it through the day on one charge? I don't think I could use my N4 that much if I tried, I sat in a doctor's office the other day for 2.5 hours listening to Pandora on a bluetooth headset while reading a book with the screen on and still made it until I turned in for the night. Perhaps it is the Trinity kernel or custom ROM I am running, I never ran my phone stock so I don't have anything to compare with. I guess some of you want to go longer than 24 hours but it would be a really bizarre situation for me to need to do that.

So I tried juice defender ultimate and it did significantly increased my battery life. I am now getting about 30 hours or more with my regular usage. Even right now I have 63% remaining battery with 1 hour screen time and 17 hours total run time, see screenshot for usage.
