(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.

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.

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)

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

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 %.

I know this horse has been beat to death, I'm just hoping I can get maybe one bit of info that will help me resolve this issue before I just swap out to another phone. I really don't want to, but I'm just so sick of being chained to a charging cord all day. My phone should be able to hold a charge for at least 1 day, I don't even use it that much!
So with my little tirade out of the way, let me give you the facts I've got a Samsung Galaxy S II/SPH-D710, and the battery just drains down so fast, and the phone's barely 6 months old. I've downloaded numerous process monitoring apps, designed to see what's going on, and they all point at WiFi being the culprit. The phone never hits deep sleep because the wireless is keeping it awake. Sure enough if I turn WiFi off and I go 3G/4G all day my battery is fine. Problem is I can't get to that next level and find out what program or process is causing the WiFi to be on all the time. Even more frustrating, every time there's an upgrade like FI27 or FL24 which I'm on now, the battery works fine for a day or two. Then something kicks in and destroys the battery. My thought is it's got to be an app, I just don't know which one.
So before I kick this piece of **** out the window, I was hoping someone could please help me figure out what app/process is the cause of my battery drain.

Get DS Battery Saver. It will force all of your stuff off when you turn off the screen so that it will go into deep sleep.

Get a new battery?

Apps, batteries, ics vodoo it's a host of things that can solve your battery drain issue. Being that your phone is 6 months old I have to rule out the battery. The fact that your on ics is going to be main culprit, stock ics was not the best at managing battery use. There's something revving the crap out of your Wi-Fi, while Wi-Fi is on even while your screen is off there are processes going on in the background that are using Wi-Fi to send receive, update, sync, you name it and all you need to do is pinpoint these processes.
Some apps in the play store can help, but some of these apps can consume battery also, so it's best to delete it after troubleshooting.
If your phone is working properly and your not a social media junkie while it sleeps it should not be using any battery at all, just enough to keep your processor awake.
I keep notifications are sync off on my phone, while I'm out and about I'll check email or do a quick sync if I want to check for some incoming whatever. Most of the time I want info on my terms, not every minute with chimes beeps or lights flashing.
If you use google maps disable background location reporting, location services just use "location and search " disable Wi-Fi and GPS usage for location services.
This is a start, but I recommend Jb ga10 stock/rooted to give your phone a stable os.
I run stock/rooted Jb de-bloated with minimal apps, no games (all the games I like are on my Galaxy Tab 10.1) I use my phone for calls........... navigation and media player while driving. I get 16 to 20 hrs on a charge.

I get about 20 hours on the Vanilla RootBox JB ROM. YMMV. I also had terrible battery life on the stock ROM and every other one I tried. This is the first ROM that's bested 10 hours. Again, YMMV.

what rom are you on? tw? cm?

Have you used Better Battery Stats? Or the JB release candidate GB08?

Not to raise the dead, I've just been busy, but this is still an issue for me. I upgraded to JB GB27, and I love the GUI, it’s such a step up from ICS. But I’m still getting **** for battery life. Yes if I use DS Battery Saver it works and I get good battery life. However all those programs cause flaky restart issues. The phone will just restart for no reason. More importantly it’s not getting at the root of the problem.
IRL I’m a computer tech and I can’t just let this go, as previously stated I’m tired of being shackled to the phone charger. I’ve swapped in a new battery, it’s not the battery. I even turned on the setting “Keep WiFi On > Only when plugged in”. That did improve the battery a little, but I still can’t make it through the day without being charged. I’m on the phone maybe combined 30min of phone calls, 30 min checking email, and an hour or so of miscellaneous watching video etc. I know heavy users that are on their phones all day, or let their kids watch Disney movies all night. I’m not that guy, I’ve had numerous cell phones and never have I had one that couldn’t hold a charge all day.
I will be diligent in monitoring this thread, please give me your troubleshooting tips and I’ll report back with the results.

Downlpaf betterbatterystats. And find the wakelocks.

Can do, will let you know at the end of the day.
EDIT: Actually I read multiple issues with SG2 and BetterBatteryStats. However your wakelock comment made me stumble onto the app Wakelock Detector. Again I'll run it and report back. Thanks for the point in the right direction.

Ive noticed no better or worse battery between being rooted/custom rom and stock not rooted. However my phone gets about 16 hours on average. My friend has an epic as well and gets only 10 hours. I feel as though it depends on the user and apps. Facebook is a silent killer. As is any app that uses backround. Best setup ive had so far is billgeryans Quattro Rom with ds and greenify. I pulled a whopping 25 hour minimal use before charge and 13 hour heavy use day.....

So how do you stop it? Do you just have to close out of every app before you set your phone down?

exiting apps don't stop them. you can freeze and unfreeze them.

With titanium backup. You can also install greenify. It puts your apps in hibernation when your screen is off. So basically it's like freezing and unfreezing. Tbh I think it's better using greenify.

titanium can and you can create a widget to do it easily per app.
or
app-quarantine in playstore
or what I do:
shell commands usind connectbot widgets with a command like this:
pm disable-user com.facebook.katana
pm enable com.facebook.katana

so my 2 cents:
1) get a second battery and charger.
2) betterbatterystats to identify "bad" apps and either get rid of them or deal with them.
3) "autostarts" app to stop crap from auto starting on boot that you don't need running as a service.
4) dim screen! huge huge savings. keep it dim enough to use the phone.

Battery issues well I have a solution that won't solve but greatly helps. It's called greenify. It puts all running apps in hibernate mode. It's not like a task killer that just screws things up. U can choose what u want to hibernate and all that jazzy stuff. It's worth a shot. All in all if you want a bada$$ battery efficient rom go with wcx stock rooted rom. It's simply amazing. Hope I was at help

Check out greenify if you're rooted. It removes all currently unused apps and processes from memory, essentially putting them into deep sleep. That combined with ds battery saver and watching your wake locks will drastically improve battery life:beer:

Okay so does Greenify do this freeze automatically, the interface is a little clumsy. I appreciate all the help guys.

Annoying battery thread

Whats normal battery on this phone for you guys like? I really don't think mines normal. I've never gotten 10+ hours battery life on a custom ROM. never, and I flash like crazy, I've tried cm aokp aosp Jedi cm, ics tw ROMs, and Jb tw ROMs. Never over 10 and on tw jb I wouldn't even get over 5 hours, I'm not a heavy user, I check twitter sometimes and Facebook, a tiny bit of instagram.. not that much, with juice defender pro I can squeeze 7 hours from Jb touchwiz, and maybe 9 on an ICS ROM.. is my battery dicked? Stock koodo ROM gives me 14+ hours, so wtf? Maybe just a koodo t989d problem? My battery is physically in shape, I've monitored wake locks, checked chargers, virtually everything. WTF?

You need gsam and CPU spy to see what's draining your battery and if phone is deep sleeping.
The apps you said you use are pretty much big battery drainers BTW! I finally got my wife using the mobile Facebook webpage instead of the app. It was killing her battery and using all kinds of data while she was at work not even using her phone.
But yeah....your battery life is horrendous. Something is going on.

I have both, my phone deep sleeps. I've even UNDERCLOCKED! Still **** battery life. I'm not so big on Facebook, I don't use it too much really. Twitter though I am on a lot.

Im running the Unicef Rom v13.5 and I have been getting around 22 hours of use with around an hour and a half or two hours of screen time. I aslo just flashed it so I have to let it break in to get the full benefits. But yeah you should try checking out Anker Batteries and monitor what is using up your battery. Juice Defender I found is a big battery drainer and are you in an area with low reception?

Okay, uninstalled juice defender. I was thinking of getting the extended galaxy nexus battery, but will it really make a big difference?

Make sure you go into your apps like FB and twitter and turn off all notifications. notifications will kill your battery life.
Also, check apps that sync. you can go into your google accounts setting and turn off stuff you don't use or need to sync automatically, like google drive (just sync manually).
And turn off backups in the system settings.
lots of apps are configured to update automatically or configured to send error/usage reports, so make sure you go in to your apps and look for settings like that and turn them off.

THANK YOU
