[Q] juice defender

Aight so I downloaded juice defender free last night cause I've been having battery heat problems.....but it shuts off my 3g connection when the screen goes off and I can't seem to find the setting for it....I use Pandora radio so this is a bit of a *****.....any solutions?

Thats pretty much the only thing Juice Defender free does that can save your battery, that and turning off wifi too. So if you disable it why even have Juice Defender installed? I too tried the free version for about 2 days and could never get my wifi or 3g to come back on so I uninstalled it and thanked god I hadn't paid $10 for the paid version. IMO its crap.

Juice defender is terrible. It kills your battery. well thats my experience...

Terrible app. If it does anything then it kills the battery... Brings android system to the top of the usage list, because it shuts off 3g and wifi..
Sent from my ADR6300 using XDA Premium App

Screen is still the top on my usage.
I have the paid version. It gives you the ability to lock items (like Pandora) "on" for data usage. Then, they don't get killed.
I had amazing battery life with it on my D1. Jury is still out on the Incredible. I'm still working through ROMs and Kernels.

I use it also. It has this new feature that you can tell it your local wireless and leave it alone. Problem is it doesn't work. Keeps shutting off my wireless when I'm using it! Very frustrating.
Also their developer is not very accessible. They want all issues solved through their forums. I hate that...The best software also has an accessible support system.
The one good thing I will say about it is it has the potential for taking over all aspects of managing your phone. A one stop shop. Just not there yet...

I used to use Juice Defender with 2.1 and found that it helped battery life. However, with Froyo, it just made the phone unstable. (It'd just sponaneously reboot sitting on my hip 2-3 times a day.) After uninstalling all is well.
A co-orker's Sprint phone had the same flakyness until he uninstalled JD.

Wild! I have never had random reboots. But, we all know how unique these devices are... even between the same model.
With warm twopointtwo, it doesn't seem to be turning on all the time... or warm is somehow killing it.
dbaps - are you still in 'training' for the wifi? It takes JD a couple of times to fully learn your location (based off of towers) and remember that as a wifi location. Check under the settings...it'll tell you what percentage of training it has completed.

Those of you who say its crap obviously dont have it configured correctly. I bought "ultimate juice" and when you go into the custom or aggressive profiles you can tweak everything until your heart's content! It still seems to shut off data when Im streaming stuff with slacker and connected to wifi, even though I tell it not to. Other than that it definitely will give you a few extra hours if you spend the time to configure it properly.

Terrible app!

There is no correct configuration to this app. That is why it is called "Custom". The reason it is CRAP is due to the reason you list as a problem among numerous other features that don't work.
Seriously, why have an option to automatically tweak CPU values if the option doesn't work with 99% of the kernels on the market, which also includes the STOCK kernel?
Yeah, it's a GREAT app!

True. For clarity's sake, I was using JD free so I don't know if any other version would have been better or worse. It's possible that the complex WiFi network at work (multiple APs per floor with a centralized controller) confused things.
My phone is a droid incredible, the co-worker's is a Sprint Epic. Different symptoms - he had phone lockups requiring battery removal to recover. Rooted, re-ROMed and still crashing until Juice Defender removed.

If you use Ultimate Juice and set up things correctly. This programs rocks.
It will turn on and off your data (3g and wifi) when you need it (according to the conditions you set).
It takes a little bit of reading and intuition, trial and error, and PATIENCE.
Use it for more than 1 day. Your phone usage varies day to day.
Again, read the text, THINK, and setup the conditions according to the way YOU need them.
I get at least 20-40% more battery depending on how I use my phone. I rarely charge mid-day any more and I can count on my phone having battery throughout the most useful hours of the day.
On light to moderate use, I get at least 14-18 hours. Just for fun, I once tested it and got about 29 hours before the battery hit 5%. That's with a little texting and a few phone calls. I use the stock, standard capacity battery as well.
SET IT UP RIGHT!

I've had no issues with JD running on 2.2.
Set on Aggressive. Only annoying thing is that I get the error notification icon for Weatherbug Elite every two hours because data is shut off.

First - I've got the most recent JD installed. The old one was kind of lame. People have made some good points, but there is a lot of incorrect information in this thread...
It works. If you are *NOT* actively using your phone, it will save your battery by disabling communication you don't need. I can go to bed at 80%, wake up 7 hours later at 79%, maybe 78% at the worst case.
If you are using your phone, it's quite nice - it comes on quickly - and manages my network well (at home, uses WiFi, elsewhere - 3G).
It's not $10.
My wife is using the free version and has had zero problems.
I've never tried aggressive, but maybe I will.
I cant comment on the CPU stuff - never used that.

I've never had a problem either. I'm running Skyraider 3.5 with incredikernal 2.6.32.27. I have the free version set on advanced. The best battery lift I've gotten with light phone use, texting, data syncing and browsing was 72 hours. Same use with stock rom and kernal my best was about 18 hours before I needed to charge. I know everyone is different, but that's my experience.

When I tried it back last Fall the paid version was indeed $10, its now down to $5. Which I still believe is way too much for this app. My 3g would not turn back on no mater what I did and yes I read the tutorials many times and had it set properly.

Perhaps for you. For me (stock ROM on my dinc) it made the phone unusable. Calling that observation "crap" or "lame" is convenient, but doesn't reflect the experience that I had (and which others had).
Again, with Android 2.1 JD did help a great deal. With 2.2, it didn't help battery life but made the phone crash. This was not a positive trade-off.
With froyo, I can go two days on my incredible between charges given light usage without it. Why put up with the instability just to get a few extra hours of battery life?
For example, I'm currently at 62% after 15 hours since unplugged with moderate usage of the phone, with WiFi and Bluetooth enabled. I could just turn off Bluetooth except when I'm in the car, but I doubt it'd buy me more than a few extra hours of useful life.

Juice defender has caused me multiple problems. Was the source of phantom call drops and sleep of death!! As soon ad I removed it, problems solved.

Also corrupted two SD cards, losing all my files, because of sleeps and reboot caused by JD. Does not play well with Z and HD roms at all. Works at first but soon became the cause of a lot of problems.

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Battery can save only by low brightness, less active connections and less ram consuming apps...

Any app that claims to save battery only uses more battery by doing processes you can do yourself, so all you are doing is wasting battery instead of saving it...

well actually it does save battery but it depends on how well you know your device
if you know you can manage it yourself then ok you dont need it but it also helps by turning off data when the screen is off
but really for most people its not worth it and i would highly not recommend it

I used it on another (older) phone and it helped noticeably and I bought the plus version.
On this phone, I'm not so sure. Newer phones seem pretty efficient in the way they turn on/off radios. Currently, I can see JD offering a little benifit if you use it to schedule your syncing times at longer intervals (and you get a lot of email/notifications), and using the night time feature to shut down sync altogether during the night.
On this phone, I've actually had much better results using some customized init.d scripts put together by someone in my other phone's forum. I'm still testing them out, so perhaps I'll have him post it here once I know for sure there aren't any issues.
on this phone, those scripts made much more of a difference than JD did. here's some screen shots of the last two charges. The scripts seems to help most with saving battery when the screen is off. I'm a light user also, and hardly used my phone yesterday.

What are your settings?

I'm on Darkside Evo rom (ICS 4.04) and the jedi ics kernal basted on 3.0.8
I turned JD off last night before I went to bed and when I got up for work this morning, my battery had dropped from 68% to 48%. With JD on, I usually only get about 9-10% drop. So I'm keeping JD.
======
*edit* I had tried that cpu sleeper app (old version I believe), and I think it messed up some things I had going before I installed it, since my batter life dropped off a lot. So I'm going to reflash the rom today and set everything up again without it. I see there is a newer version in the market, so perhaps I'll try that one later.
======
For JD, I use the customize profile, and have the mobile data option enabled (turns off when screen is off),
I have the wifi option disabled (since I have it off most of the time anyway). And you can't use wifi calling if it's enabled because it turns wifi off when the screen is off.
sync is at every 30 mins
Night mode from 12am to 6am
I don't use app control, since I didn't want data enabled when I wasn't using my phone
Also, go to the google play store app, and disable automatic updating. I only have it set to update over wifi only. And be sure to disable notifications in any social networking app like facebook.
and use dark wallpapers, since the screen sucks the most juice. Mine are nearly black.
with the jedi kernal, you can use antutu cpu master to underclock and undervolt the phone. I just enabled some minor UV and UC, so we'll see how it does.

I paid for JD a long time ago....before I ever knew about programs like gsam. And when I saw it woke my phone over 200 times in a work day on aggressive mode....I uninstalled it and will never use it again.

your experience differs from many, pretty much everyone else lol. but whatever works for u. but I'm almost sure that with proper configuration even with the data left on all day u'd get more juice. that being said I'm not u and I don't use your phone so I agree to disagree

well i never trust third party anti viruses and battery savers - for a belief that they are all gimmicks has somehow been implanted into my mind during the early stages of my xda induction. But following the hype all around regarding jb i have had tried it once but didn't notice any difference - neither did it make things worse nor did it make em better - so i gave it up and now believe that a power user has many stuff at his discretion that he could configure to his liking to make extraction of juice from his pack more or less suitable with respect to his usage patterns
just my 2 cents
why fix it if it ain't broken ?

Juice defender is for noobs who don't know how to turn off sync, GPS, data or wifi.

CPU spy and better battery stats will demonstrate that this app does not cause wake locks or cause you're phone to wake to often. All juice defender is is essentially a toggle for data. And I'm apparently not the only one with a positive experience with this app. I put forth an effort to not use it because I trust most the guys in these forums especially ASD's this was just one area where personal experience out weighed others. It's a free app. Heck, test it yourself. Lol. That's the real best answer for anyone.

Anyone can turn off simple toggles. The handiest thing about JD is that it's automatic and easy to set up. I don't have to turn on and off all these various things all day. Set it and forget it.
Sent from my SAMSUNG-SGH-T989 using xda app-developers app

yeah, it would drive me crazy turning toggles on and off every single time I touched my phone to look at something. JD automates things and limits how often your phone syncs if you set it up properly.
right now I'm sitting at 18 hours up time with 72% battery left. 37 minutes of voice calls and 14 minutes with the screen on. I don't use my phone much at work because I'm in front of a computer all day, so I typically get better battery life than most people who are out-and-about all day.
I just got this phone 2 weeks ago, and I was getting about 18-24 hours total for each charge.. Now that I've got some things figured out, using my init.d scripts and JD, I'm getting about 48 hrs on a single charge.
after this charge, I'll disable JD and see how the phone does. typically at night, my phone loses less than 1% per hour. so maybe 7%-8% battery loss over 10 hours or so. before JD, it was like 15-20% loss over the same amount of time. I figure that's a pretty good test since the phone isn't being touched at all. But I'll test again, just to be sure it wasn't anything else I installed (since I had been trying different roms and apps a lot).
I haven't installed anything new since the weekend, so the phone should be pretty well settled in by now. Next charge, I'll disable JD and report back.

I just got this phone 2 weeks ago, and I was getting about 18-24 hours total for each charge.. Now that I've got some things figured out, using my init.d scripts and JD, I'm getting about 48 hrs on a single charge.
after this charge, I'll disable JD and see how the phone does. typically at night, my phone loses less than 1% per hour. so maybe 7%-8% battery loss over 10 hours or so. before JD, it was like 15-20% loss over the same amount of time. I figure that's a pretty good test since the phone isn't being touched at all. But I'll test again, just to be sure it wasn't anything else I installed (since I had been trying different roms and apps a lot).
I haven't installed anything new since the weekend, so the phone should be pretty well settled in by now. Next charge, I'll disable JD and report back.

Here's the thing. I consider myself to be a power user. Maybe I just don't know what some of these other options are. If there's a better way to do it I'm open to more education. I like to learn new things. So let's here it. What else can I use to turn off my mobile data when I turn my screen off to save battery. Something automated and easy to use.

I can tell u straight up if you're using JD to disable the internal radios and only turn them on once every 30 minutes or so you won't get as much without it to have 48 hours total time off one charge, u must be doing that, or having it switch to airplane mode inbetween certain hours. nI would also think u probably have location awareness on, and switch to WiFi at work.

[Q] Battery life poor since JB

Hi everyone,
My One X used to have brilliant battery life. I didn't turn on the screen that often throughout the day, but I was able to regularly check the news, send and receive texts, make a few calls and - crucially - keep my Wifi on for the entire day. With this setup, I was regularly getting 4 or 5 days of usage without having to charge my phone. However, as soon as JellyBean came along as an official update, I grabbed it... since then, I'm lucky if I get a day and a half out of it before I need to plug it into the wall.
I'm not running any custom ROMs: just whatever I get through official O2 OTA updates. Battery usage says that 36% of my drain is due to Android OS, with another 20% due to Maps. The rest are tiny, only 2 to 5%. Now I understand that a new version of Android might make some new demands on the hardware, but from what I heard, the update was supposed to improve battery life if anything. Even with the new Power Saver feature on, the difference is minimal, with only a few hours standby time gained overall.
Can anyone suggest anything to remedy this, or is this fairly normal? It's not world-ending and perhaps I was just really lucky to get 5 days of use in the first place, but thought I'd ask the experts before I grin and bear it. Thanks in advance for any help or advice.

19 hours and 40 minutes into this usage cycle, I've got 57% remaining. So it's shaping up to be about 40 hours of usage, down from 120 at its peak. Right now, it's also saying that Android OS has used 99% of my battery... and nothing else is on the list.
Does no-one have any idea what's going on?

Did you make an hard reset when you updated your phone?
This is why when you upgrade your phone to a newer Android version it is better if you perform a hard reset

AW: [Q] Battery life poor since JB
I suffer(ed) also under heavy drain due to maps since update to JB. But I'm convinced it's cause of Google Now. Disabled it yesterday and will check whether it gets better or not. Try disabling gnow and see if it gets better. I also had issues with gsam battery monitor in case you use this.

Would you consider rooting because custom roms like blade have great battery life

Thanks for this. Your suggestion got me checking for other people having issues with Google Now and battery life. I disabled it as you suggested and I'm definitely seeing an improvement. It's still not as good as it was, but I think I might be able to squeeze more than two days out of it now.

Do you have stock rom? Because I've just upgraded to JB yesterday and flashed a custom rom, and since then my battery is like 3 times more powerful.

You should definitely switch to a custom rom... Ever since I upgraded to JB I've seen a massive improvement in my battery life.. From barely making it through the day to almost 2days of my typical of usage.
Google Now does seem to kill battery as it polls the Google maps app a lot.. So I usually open task manager to make sure it isn't running in the morning background.

Help Battery Life

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?

last picture......
Should I just take it into Sprint and get a replacement???

I am running Macintosh 3.0 and I have power saver turned on, and I run DS Battery saver all day long. I am getting 2.5 days solid with moderate use. I am pretty sure DS Battery Saver is what is saving my battery. Let me know if you want to try the app. I have the .apk saved on my sdcard.

Also try uninstalling and reinstalling facebook. My girlfriend's phone (GS3, not a note) went from 8 hours to probably 14 hours just by using the mobile web version of facebook instead of the the app. Facebook is atrocious at making apps.
But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.

I will uninstall Facebook, and test it out. Thanks!

OP. Your problem is not your ROM or anything else. Jeeze people.
Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.

My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Ok I turned off Google Now, network-based-location, and Sprint Connection Optimizer. I have also installed DS Battery Savor Pro running in balanced mode. I dont have facebook installed anymore also. Here are the screens, still just as bad........

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

What of the borderline useless bells and whistles do you have enabled? I.e. face recognition/unlock, auto-brightness, SPen battery saver etc? Things like battery savers unsurprisingly don't help so i'd nix it as it is only wasting battery.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

I am going to try that now, going to do a wipe of everything and not install anything except the battery tools.

No face recognition/unlock, auto brightness is enabled, but with that little screen time does it really matter? No SPen battery savor. Thanks for the suggestions.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

I would get a replacement. You should not have to turn off all thr features to get decent battery that defeats the purpose of having a smartphone.

Bought Ds Battery savor. Charged phone to 100% put it in airplane mode went to bed at 11pm (phone at 100%), woke up at 7am and it was at 8% Fail! 0 screen time, 0 talking, zero everything and lost charge in a little over 8 hours! Going to use it in florida the next week, with my extra batteries and most likely going to return when i get back
Thanks All for your suggestions!

Has anyone disabled samsung push service. If not does it drain battery I have had it disabled since I bought the phone because I never use samsung chaton or other aops **** that but I want to start to use Chaton but not if push services has a big affect on battery.
