[Q] Galaxy Note II battery drain -- Polaris constantly running

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.

OP stated he has already disabled the app but it continues to run/drain the battery.

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.

Battery Drain and "Android OS" data hog?

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

[Q] Battery drain on Note 2 after 4.3 update

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.

The only battery apps on my phone are the 3 mentioned above, so I don't know what the battery monitor that keeps my phone awake is. The drain existed before I installed these apps. I have read that Chrome could prevent the phone from going to sleep but it is disabled on my phone.

Here is detail-
Disable sync always, enable when needed.
Disable wifi always scan from settings
Display set to auto
Uninstall apps of playstore you rarely use
Use widgets on lock and homescreen as less as you can (I don't use any)
Disable motion on settings
Freeze all bloatwares by TB except allshare and samsung content agent
Install Agni kernel, from agni control app-
profile: normal
Governor: pegasusq
Scheduler: cfq
Don't touch other tweaks, hardly you can tweak sound boost.
THIS GIVES ME A SATISFIED BATTERY STATUS.

Wew 4.3 does have may bugs

Slow and overheating

I have an AT&T variant of the M8, but I've rooted it a few months ago and installed a stock HTC Sense ROM (without any AT&T bloat).
Starting this week my phone started working really slow, and also started to heat real bad. It was never like that (in the year I have it),
and it didn't start right away after I rooted and installed the new ROM. Also, I didn't install any app that could cause it, and I tried uninstall some apps anyway, as well as disabling all of my Xposed modules to see if maybe they cause this, nothing seem to work.
I'm really baffled as to why this happens, and I want to try everything I can before doing factory reset (which I'm also not sure about how to do this on a rooted device).
If anyone has any idea, I would love some help.
Much thanks!

Hi man,
Give a look at battery stats to see if there is an app that is draining battery.
I suggest you to download Gsam Battery monitor (and Gsam root companion too) from play store. It will give us more detailed informations about battery draining.

Hey thanks for the reply.
From the time I had Gsam running, I see that Google App and Sense Home are both taking most of my battery consumption. (Both at about 20%)
My phone is still unbearable to use and I have no clue why....

Can you post some screenshots of Gsam (Both main page and app usage detail), after a full battery cycle (from 100% to 10% for example)?
Also, can you download Wakelock Detector and post some screenshots of it? (WD it's an app that can help you identify If something is keeping your device awake).
Anyway, you can easily do a factory reset from recovery.

Hey, thanks again for the reply. The situation actually got fixed, sorry I didn't update.
I woke up yesterday to an update for the Google App, and since then my phone works just like it's good old self.

Battery Drain

Ever since I updated to 8.1.0 with December security patch, I've noticed my battery draining faster than normal. I was getting 4-5 hours of SOT with around 45-50% battery left. This was after being off the charger for 12-16 hours. Now I'm getting about half the SOT at similar numbers. Anyone have any ideas?

Excuse my stating the obvious, but you need to find what process or app is using the battery. You should be able to get a rough idea just using the new features under Settings>>Battery. It will identify which apps are using the most juice. Run the phone in Safe Mode to see if your battery life goes back to normal. It could also be a service like Google Play Service which sometimes wigs out and starts chewing battery. Are you rooted? If you need more detailed information there are battery drain apps available to help isolate the problem (BBS and GSam). These apps require root to give the best results.

Not rooted and currently locked. I've downloaded GSAM and have adb permissions and it simply says things like Chrome, RCS Phone and Play services. If you see from the photos below you can see what I'm talking about. Chrome currently isn't that bad, but yesterday and the past couple days it's been like 9% or more of the battery.

Two things: I've never seen phone or kernel use that much battery. On one page phone usage is 33 seconds, yet it used 9% ? I think RCS is running the background all the time. See if you can toggle it to not run in the background under Settings>>Apps>. High kernel I'm guessing is a kernel wakelock or multiple. You've probably loaded app(s) that are creating the problem, but you need to find out which one is causing the wakelocks. There is a wakelock detector "lite" app that doesn't need root but I don't know how well it works. I know the root version works well. Lastly, on the first screenshot with the battery, scroll to the bottom of the page and see which apps are listed there. I'd be willing to bet if you ran the phone in Safe Mode, your battery drain would disappear, meaning your user apps are causing it.

Well in safe mode my drain is gone so I'm not sure which app is doing it, but to directly answer your question about the RCS it is an overall app meaning it is related to several Google play services. I'll upload a photo of it. I have to reboot into normal mode.
Edit: I'm wrong about that it was the play services.. I'll have to start uninstalling the apps to determine which one is draining the battery I guess.

RCS can be a real battery hog, but I don't know why. I don't have RCS on AT&T. Do you use Messages as your primary SMS? Open Settings>>Advanced and see if you can toggle off "Enhanced Features". Open properties and check if it is using battery optimization. If it is not, set Messages to battery optimization. You can always turn these back on later if the battery drain remains.

My battery life has been restored to pretty much the same as it was with 8.0. I also noticed poor battery life after installing the 8.1 update, even though they changed the way battery life is estimated with this update (supposedly). Something just felt off, but now everything feels great! I am fairly certain what changed is installing the Greenify Magisk module and/or the Google play services doze module (this enables battery optimization on the Google play services app). Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

Not sure which one really made the difference because I installed them at the same time. However, there is definitely a major difference!!

In my experience that's really good.
Before 8.1 I noticed about 11% per hour during screen on use and about 0.33% per hour while on stand by in my pocket or a little bit better if it's just sitting on my night stand not moving while I'm sleeping (I think doze is more extreme in that situation) which seems to match what you are getting. Based on that screen shot I think that's like 8 hours screen on time over like 35 hours for a full charge. I've done a little bit better but not much. That's excellent battery life.
Since 8.1 it has dropped. Best now is maybe 7 to MAYBE 7.5 hours over maybe 26-28 hours. In my experience battery life always drops after an update but this case is far from the worst. I remember when my Nexus 5 updated from KitKat to Lollipop. The battery drop was awful and to make matters worse the battery life of the Nexus 5 was pretty bad to begin with.

So in my last reply I thought I was wrong about RCS Phone app being a conglomerate of several apps in the phone. For some reason I couldn't find the information I needed at that time. I wiped my phone and started over after posting this thread. I was trying to isolate the misbehaving app. I thought it might have been greenify actually, but no the drain has returned to a lesser extent though. Here's some photos of this RCS app from GSAM.

I'm not sure what is causing the drain at this point. I've installed Better Battery Stats to locate the wakelocks so I can ignore them through ADB.

Have you tried disabling RCS ? (Post #6). BBS is good for idle drain, active drain not so much. It's best run overnight without touching the phone for 8 hours or so. Pick the phone up in the morning and create/save a log file as quickly as possible. Post the log to the BBS thread if you need help deciphering.

I cannot disable it since it is comprised of multiple apps. You can see it in the pics on my last post.
