So my father recently got the GN2, but he's really disliking the battery drain compared to his old iPhone 4. He said that he could finish the day with about 70% battery leftover, whereas, Note leaves him with around 30-40%. I checked his battery usage and there's about 12-17% coming from Polaris 4.0. I already disabled it, but for some reason, it's still draining his battery. Is there anything I can do to improve his overall battery life as well as stop Polaris from being used?
Uninstall it or is it a stock app?

Stock app, unfortunately. I have no intention of rooting it since I haven't done that in a long time and I'm just not confident with messing around with someone else's phone.
Also, I know it's a problem specific to mine since other people don't root there's and they don't have this problem.
Does anyone else know a possible issue?
Try going in and force stopping the app. I noticed apps will continue to run after disabled on occasion. Then reboot and see if it fires up again. That should stop the battery drain. N2 gets great battery life.
Does your father use the app? If not go to settings/application manager select polaris. You should see a disable or uninstall updates button. If it is the updates one, select it then go back in and hit disable button after it is done. This will remove the app from the system but not the app file itself. Will keep it from ever running again until you decide to enable it again. No root needed.

Yeah, I already disabled it. I checked again today and it didn't seem to be draining battery life.
After around 12 hours of use, he only has around 60-65% left. He doesn't use the phone as much as some other people, so I'm surprised it drains as much as it does.
I'd say that's about right on stock with everything running. you could always disable everything he doesn't use and see if that helps. Also check for wake locks. I disabled fast dormancy and saw a major improvement on wake locks. Not sure if that's possible without root, but worth looking in to.

Root, install Better Battery Stats, find the culprit. If uninstalling Polaris doesn't help, it could be something else.
S-Pen detection, motion settings, smart-stay, etc are all drainers. Disable them if he doesn't use them.
Location services drain too. Try installing Autostarts and disable unnecessary startups. I get a good 2-2.5 days out of the phone with ~5+ hours of screen time after doing the above.

Good point on the S-Pen features. I disabled some. His active battery usage is quite good, but he says the standby is terrible.
Hello everyone.
Don't know if this is a known problem, but after upgrading to 4.1.2, battery doesn't last nearly as long as in ICS or GB. I need to plug the phone one or two times for a while through the day.
Besides, something is hogging the data in the background. I use Onavo Count to keep an eye on data usage, and recently an app identified as "Android OS + Others" appeared on the top list. It sucks around 5 MB a day, which isn't much, but my monthly data cap is pretty low and this never happened before 4.1.2.
Any ideas? Do you have the same issue? Thanks in advance!
Regarding battery drain I advice you to install Wakelock Detector to see which processes are using most of your CPU and battery overall.
After that, if your phone is rooted, install Greenify and freeze every app that you want to freeze when phone goes in standby.

Greenify works with system apps?
Donation version can greenify system apps.
Alternative, although a bit different, is to freeze apps via Titanium Backup.

Try doing a clean install again(wiping data)
Or disable usage and error reporting services...also disable background data(not sure if it's on jb as am on cm10)
Also if u don't use Picasa delete mediauploader.apk in System/App
Should decrease quite some battery and data use

What most people think android os is on a battery use log is wrong. For instance, write down your android os number, go watch a YouTube video through the app.. android os usage should have risen in the battery usage and data usage number. What android os is, is a catch all for apps who don't store stats for data or battery usage under their own name. YouTube comes up in data and battery usage but in tiny tiny amounts, compare it's number to even the shortest video you've watched and you'll see it doesn't match up but what's added to android os does. I use YouTube as a simple representation of multiple apps that do this. Battery usage in android devices can usually be backtracked to data usage, turn data off battery life doubles even triples sometimes.

Thanks, just did a clean install, rooted, and deleted mediauploader.apk. Will report back in a few days.
Nope. Got rid of MediaUploader.apk and the phone is still consuming a lot of data. No difference with battery life either.
I had the issue of battery drain, and phone heating up, and the phone lagging all time, for my XS. Flashed official JB, problems re-occurred after a few weeks. Now recently I again did a factory reset, and has been selectively installing apps/enabling services to locate the cause. Till now I have seen the google location reporting (not the general location settings) consumes a lot of battery. You can try disabling it (from google settings) and see the battery usage. Let me know if that was the cause for you also
Yesterday i installed CM 10.1.3 from official cyanogenmod site. First few hours i had big battery drain and i saw that the phone isn't going into DEEP SLEEP but only at 384 MHz. I thought that some app is staying on even with locked screen so i downloaded Clean Master and set it to kill apps when screen is off and also i clicked on "don't keep activities" from dev.options menu.
I discovered one bug on this rom - the NFC cannot shut down, is it possible to stay at 384 MHz just because my NFC is always on? If not, give me some suggestion please

Get rid of clean master. Get gsam and cpuspy from playstore. Sounds like you have cpuspy or something similar.....but gsam can tell you what is keeping your device awake. Then you can deal with it....or search on the app keeping device awake and find fix.
Sent from my Nexus 7 using xda app-developers app
I don't know if NFC would prevent deep sleep, or if clean master would help ( I'd uninstall it ), but I've spent a lot of time researching battery life fixes, so here's some tips:
1. Get the Better Battery Stats app - it's essential. You're most likely going to look under the Partial Wakelocks section from the dropdown. That'll help you narrow down which apps are keeping the device awake. Kernel Wakelocks are important too, but require some research into what stuff means. Select your reference point ( Boot, Unplugged, etc. ), then try to avoid using your phone for a couple of hours from that event at least before checking this app to get better results of what's causing issues.
2. After finding which apps are problematic, you can uninstall them, freeze them, or do the following if you prefer to keep using them without hurting your battery as much:
Install Greenify and hibernate the problematic apps. Hibernating an app prevents it from running unless you start it.
For extra measure, also get ROM Toolbox ( not sure if you need the pro version ), go to "Auto Start Manager", and uncheck certain things for apps ( like Facebook auto starting on location change, for example ) to lessen app wakelocks. You can also use the paid AutoStarts app in the market with the red car icon if you prefer something simpler.
**Note: disabling certain autostarts can break a function of an app, or the whole app, until you enable it again, so be wary of that**.
3. I don't believe this is even an issue anymore, but some roms had issues going into deep sleep on multi-core devices. Eugene373's CPU Sleeper should fix that. I haven't looked into this much though, so not sure whether it works or not.
4. I found this thread on the Skyrocket forums really useful when my phone was losing battery while charging: http://forum.xda-developers.com/showthread.php?t=1759541 .
Also, to save more battery, keep your screen at dimmest system brightness when you can, and turn off sync, data, & WiFi if you don't need it. GPS *should* be okay on all the time, because from what others say, GPS only wastes battery if an app is using it, so if you deal with the app, the GPS is fine.
tl:dr;
Not sure if NFC prevents sleep or if clean master helps. Use Better Battery Stats to find wakelocks. Use Greenify to hibernate problem apps. Use ROM Toolbox's "Auto Start Manager" or AutoStarts to stop problem apps from auto starting.
Oh....another long time habit I have is to reboot after you unplug from charger....every time! This used to be a common fix.....and I still do it.

I tried your trick but it didn't work
Anyway, i downloaded GSAM Battery Monitor and also Greenify. I stayed like 1 hour and after that i opened GSAM and there was information that my battery drain is caused of Media Service. "Downloads" system app is working in background and it is preventing my phone to get into Deep Sleep. I tried to add downloads system app into Greenify but for this thing i need to get paid version .. anyway, i will not pay it
What to do now, at least now i know why i cannot enter in deep sleep - because of downloads system app ^_^

Titanium backup can convert any system app to a user app. Then greenify will see them. The catch 22 may be that it only works on titanium backup pro version. LOL

My note3 also had a deep sleep lack this week. The culprit was Clean Master itself. Probably they messed up something with the last update. Beware.
Hello
I have had a massive battery drain problem on my Note 2, a couple of days after the 4.3 update. While being idle during the night it loses 25% to 30% of its battery and while using it I can literally see the percentage drop. I have tried everything that I could find on the net. EVERYTHING! Nothing worked. These included: Factory reset (twice), letting the battery frain completely and then recharging it while the phone was switched off, switching off all sync,disabling bloatware including KNOX components (the actual KNOX app is not installed), installing only a few apps after factory reset, using Gsam, Wakelock detector, Deep sleep battery saver (which could not make my phone sleep), no GPS, no 3G, wifi on only when needed and more besides.
The phone is only one year old and unrooted. On 4.1.2 it had a beastly battery performance of almost 1.5 days of normal to heavy use, with 300 apps on it. Now it cannot go for more than a few hours with the same use.
I cannot say for sure but it seems to me that the drain is the same when it is sleeping and when I am using it. Wakelock has given me a 75% awake time even though I only use it for 15-20% of the day at most nowadays. Battery settings show everything normal, or at least I think so, eg Screen 35%, Android OS 15-28%, Voice calls 10%, Android system 5-15%, Cell standby 7%, Device idle 4%, Media server 4%. The batttery chart shows a constant steep drop all the time.
The problem started one day when the Media server went mad consuming 50% of the battery. After I did the factory reset it has never again been a problem but the drain still persists.
I have also read that it's a mess up between syncing of Samsung apps and Google services, but I have no way of verifying that.
Can anyone help?
Thanks
I had the very same problem until yesterday myself but think I found a solution on the web.. Uninstall Google Search and Google Play Services and the goto the Play Store and wait for them to reinstall and that's it....! As I found that there is a bug in Google Services (Nlpwakelock and Location service)
Hope this helps...?

Thanks. I already have Wakelock Detector on. I mistakenly wrote "defender" instead of detector on the original post. It gives me Viber and Messenger as the most active wakelock apps. But they both were not installed when the problem started. Besides, on the 4.1.2 they created no problems. In essence I believe that Wakelock Detector cannot help much. Whatever this problem is , it is well hidden. Thanks for your interest and help anyway. Much appreciated.

Which kernel you are using? And also i recommend using Greenify. Widgets usually eat a lot of battery, I went from battery lasting only 8 hours to get my battery use only 30% in 8 hours.
What i did: installed wakelock detector, gsam battery monitor and better battery stats.
Monitorized the wakelocks.
Applied greenify to the apps which were waking most
Removed widgets which were waking alot
Installed Toggle 2G.
Kernel settings: 200-1600mhz | zzmoove | AFTR+LPA | Multicore power saving (SCHED_MC) = 0 | GPU = stock settings
Works like a charm for me. Hope it helps! Any question, ask!
I've read all sorts of things about this problem since I updated and got hit. I have too much app data to lose by trying the factory restore (which by all accounts shouldn't change anything anyway since you'd still be stuck with 4.3)
I finally decided to try the age old blackberry cure-all: "if in doubt, pull it out" (the battery). Since the entire issue seemed to be related to battery caused problems (ie slow charging, fast drain, etc) it made a lot of sense.
And it worked.
I think the main reason this isn't more commonly tried to fix issues on Android is the same reason I didn't try it earlier. My case is pretty serious and isn't easy to remove. I'm glad I did take the time to take the case off though or I could have ended up wiping my phone.

Thank you for the suggestion. I have already taken the battery on and off several times. It had no improvement. The phone is only a year old, that is why I don't believe the battery is the culprit. Besides, problems started only after the 4.3 update. Before that it was working perfect. Too much of a coincidence.
Sorry to hear that it didn't work for you
I'm not saying the battery is faulty in any way - however removing the battery and letting the phone power drain completely seems to stop whatever process is running under the buggy 4.3 long enough for it to work again as intended. It's basically just a more thorough way to reboot.
As I said, I've read all sorts of suggestions, many of which don't work for everyone (such as the factory reset) - this is hopefully just one more thing for people to try before they end up wiping their phone in desperation. I mainly posted here in the hopes that others with this issue that may not be forum members can get some more suggestions.
At least for me, wakelock and all the other diagnostic tools at my disposal showed nothing different to before the update. Many other people have found that the Android System is using a lot more of their battery than normal or some other apps are involved - if this is the case, it's likely to be a combination of things causing the issue (the firmware, the drivers, apps, hidden Samsung processes, etc).
Also, for what it's worth, I found that Knox supposedly wasn't installed (when I find it in the apps list, the button to install it is showing...). But it's showing in the list of apps so it must already be installed. I dug through the list of running processes (had to show the system processes too) and I discovered that several Knox and some other new Samsung processes were indeed running.
One other quick tip - If you wanted to check/tweak the 'developer options' and can't seem to find it any more, that's because it's now hidden since 4.2 - go to 'About Device' and tap 7 times on the Build Number. I tried disabling all background processes however it seems this only disables application level processes, not system level processes but if you've tried everything else, it can't hurt to try playing around with some of the options in there.

Thanks mate
I think you are right. It is probably a combination of many things. I have opened the Developer options some time back. The one thing that I do for sure in there is limit background processes to 4. Besides that I don't experiment much, exept maybe to change transition animation scale. I am actually thinking of rooting the phone and downgrading to 4.1.2. It was just fine before. I can live without the 4.3 add ons.

Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-

Wew 4.3 does have may bugs
Just a general question, i have no problem with my devices battery life during useage, but whats annoying me is how much battery life i'm losing when the device is "asleep"!
i can lose between 10 and 25% battery when the device is asleep overnight, or while i'm at work.
this isnt a one off, it seems to happen most of the time, so i'm having to charge it every couple of days, rather then once or twice a week.
is this a general problem, or do i need to do a reset.
thanks
There are many apps found out there (some need root) that can track down what's eating the battery and or preventing device sleep. Google Search app is probably one of the culprits. I disabled it long ago.
If you're not rooted, try to disable some "bloatware" apps in your device settings > applications. .... If your rooted, freeze apps from self-starting using greenify app or remove with Titanium backup app. Just backup them first
I could go on and on, but at least some pointers where to start. Good luck
Have your wifi sleep when not in use. You may have some apps hijacking your bandwidth. You should only lose a few percent overnight...

I have the 8.4, fully stock and hardly a thing installed on it (it's like my 5th tablet for use) and I think its at 50% after idling for 15 days.
only thing that beats it so far is my Nook HD+, which probably idles for 4 months, literally.
having the same problem.
i do have google search in my pages. disabled it , gonna see how it goes ...
whats a good app to recommend that i can check out what is causing my device to wake while it should be asleep?
im rooted btw
