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.
Can an expert scheme in which is better method and why?
I removed lots of bloats apps from here and feel like my phone drain faster than live them on or disable them. Any experts?
disabling an app disables it so the system knows not to use it. uninstalling an app gets rid of it so it's not physically on the phone. If you want more space on your internal memory uninstall the apps. If your noticing more drain check your battery stats and your data states in system settings. There has to be an app or something doing it. The disabled apps shouldn't because they're disabled.

I use CPUSpy to keep an eye on if my phone is doing odd things. For example the other day my battery was draining like I was constantly using the phone. CPUSpy confirmed that to be the case ... my phone was not going in to deep sleep.
BetterBatteryStats will give you an idea of why your phone isn't sleeping properly (assuming that's your problem). In my case, it turned out to be the Google+ Camera Upload service. It was constantly holding a wakelock, so my phone wouldn't sleep. I hadn't even configured Google+ so I'm not sure WTF it was doing. I froze the app in Titanium Backup and haven't had a problem since.
Also... just IMHO - I don't remove stock apps. Freeze them in Titanium Backup. That way if something goes bad after freezing an app, you can just defrost it and resolve the issue.
I have Cpuspy check for 2 conditions. Both went to deep sleep fine. The difference is stanby time. Even phone is in deep sleep, the % battery goes down faster for Rom with all bloat s removed

Check your cell standby. How much battery is it using. If your phone has to keep looking for signal it's going to use more battery.

This is driving me nuts!!! Since a few days ago every time I'm away from home at work, I get GPS blinking notification with ongoing message of "Searching using GPS..." while it's draining my battery like crazy. I'm not a noob, My phone is very light on apps, Google Now is disabled, Google location service is disabled, only one weather app and I disabled using GPS in there. Tried using GSam Battery Monitor to see if I can narrow it down - no help. Switched from 4G to wifi, still nothing. Of course I can turn GPS off for a problem to go away since i only use GPS in the car. But the problem is that I had my Note 2 for 3+ months and never had this issue before. Plus, I haven't installed any new app in at least 2 months. No life wallpaper, no fancy widgets that drain your resource, no social medial connection what so ever. All stock, not rooted. Using Nova Prime launcher, and a few widgets like Smooth Calendar, Circle Launcher, Rings Digital Weather Clock (with weather disabled), Fast Boot widget, Widgetsoid, Zooper Widget, and Android Weaither (GPS disabled).
That all that I have. Any idea how to resolve this?
Maps. Look in my guide to minimize the drain caused by it. But the best solution is to disable gps.

Do you mean the link in your sig? and btw, where do you access Location Settings per your guide? ... never mind, found Location Setting under Maps. Just disabled "Report from this device". Maybe that will help it?

Funny that I had all that map stuff disabled, and it was still searching for GPS. But as soon as I stepped outside of the building where I work - it stopped. So something was trying to update location through GPS and could lock into the signal, thus searching and draining battery. Only happens in the building where I work. I guess the easy solution is to toggle GPS on/off. But still, would be good to find a source of which app or service is doing that pinging...

Hi! I would like to know what are some good apks for saving battery when the screen is off. I have greenify right now and it works great. I have tried deep sleep battery saver and du battery saver and dont work much for me. I have great battery life but would like to extend it more when screen is off/locked. Thanks!
Get Skyhigh Kernel (root). All the rest is placebo.
Battery life is related to usage patterns, short of underclocking; no app can help you there. Turn off WiFi, Bluetooth, NFC and all crap you don't need, and turn them on ony when you need them. Change your screen timeout, so it turns off quicker when you put it away.
My ultimate battery saving tip is power off the tablet when you don't need it.
Xposed module Unbounce for screen off battery life.
Thanks guys I use Greenpower now and it does the job. I just wanted something that would disable wifi or gps when Im not useing a certain app after 10mins.
It's mostly sync and/or location. Turn those off and your tablet will actually sleep (and wifi off when sleeping setting).

My Tab S can go weeks with just a tiny % drop. Just disable all the Google crap, there are many threads on it. No greenify or other apps will do as much for your battery life.

Thanks for the tip! Yeah I stopped useing battery saving apps since drain more of your battery. I use greenify to hibernate most of my apps and only wake up till I open it. I will look into disableing some of the google stuffs. Lol I use the bing search app instead of googles.

On my old phone (2.3.4) I used Task Manager from ES
Do I understand you right, that we need both tools you suggested, because there is no "autostart" app that also disables services ?
Could you please give us an idea/list of disabled services and autostarts

The autostarts app just disables apps you dont want on when you just turned on your tablet. They still work when you open them. But for services, there are too many.
i am having crazy active (27%) and idle (5%) battery drain. using ex kernel manager i can see different wakelocks. i hsve been screwing around with them and haven't made any real progress. is the flash 2.05 still very battery efficient? id my problem isn't solved will ex kernel manager still work for this kernel to set wakelocks, governors, etc? do you recommend another kernel manager instead. i downloaded the wake locks detector app and every time i opened it it just said "failed to complete task at this time." it had SU rights. idk whst the problem was. im having a hard time finding whats all of a sudden doing this to my battery. i did flash some launcher mods. this started right after that. last night i reflashed the developers stock launcher and things looked great. now theyre back at being bad. would a factory reset in twrp allow me to save my data and maybe fix the issue? please help
What apps can I use without wake lock dector functioning. Could I have a virus stopping it from functioning?
Check your cpu consumption. Use exkernel manager or some other tool for the same.

Here's what I'm seeing. Google photos looks to be the culprit. I need that app. What should I do? Uninstall updates and reinstall them? I cleaned the cache for the app but they still stayed at the same levels shown here. Cpu is usually running at 300MHz. It's not shown in the screen shot, but most the of the other cpu consumption is at 1.9GHz. it's like 9% or something. What do I do with google photos?

Edit: i stopped a backup of some stuff on Google photos and the drain is still the same. It's not backup causing the issue. Something else with the app is doing this.
Have you tried clearing its data and cache so you get a fresh start, so to speak?

Did last night and it didn't seem to help.
So better battery stats seems to be telling me that google photos is the problem. I use the app so this sucks. Otherwise I would have just uninstalled it. Can I use adb shell commands to disable its wake lock? If I do that, I'm guessing it will not upload pics and videos to Google drive UNLESS my screen is ON, right?
TK has this (
) YouTube video showing what I am asking. Keep in mind I actually AM rooted. I don't see any options in batter battery stats to disable wakelocks. It just detects them.
I would again ask To check cpu consumption

Here is a pic of the cpu stats. Everything above it is very small or 0% cpu seems to be where it should

Guess what!? It appears that the photos app was just trying to upload stuff to my Google drive. Since my internet is so horrible it took literally days. Once the uploads completed my battery drain returned to normal!!
Now I'm seeing this. What is going on. Seems like after every update or the littlest thing, or even out of the blue, battery drain occurs. I just flashed EX kernel 1.01,did some various updates in the playstore, and flashed some launcher mods.
I was seeing like 8% active drain and .5-.7% idle drain on EX 1.0 and only sharkie launcher mods. Now SOT sucks and so does my battery.
I had the same problem till I turned off instant tethering. Helped my battery life significantly for some reason. Doesn't really make sense.
(Settings -> Google -> Instant Tethering)

I didn't make any changes there before or after updating though. Here's what I have in my tethering settings.
I had this tethering acceleration on,but it was on when I was getting awesome battery life too.
And what about these kernel wake locks? Is there actually an app that blocks wake locks? Wake lock detector would never work for me for whatever reason. Better battery stats seems to identify wake locks but it doesnt give you any way to actually do anything about the wake locks.
By instant tethering, I didn't mean the tethering in the Network and Internet part. I attached a few images that might make it clearer. (Settings->Google->Instant Tethering). I think this helped cause I keep bluetooth on a lot.
If I recall correctly, powermanagerservice wakelock is the catch all for all the partial wakelocks, and power manager display is just however long the display has been on.
Wifi scanning and BT scanning were both back on(previously turned off) for me after the JAN update.

Thanks for the reply. I found what u we're talking about with those pictures. Instant tethering under google was not on. I want wifi scanning on but I don't want the BT scanning on, and it didn't turn back on after the January update for me.
Without wifi scanning will wifi work with only the toggle button in the notification drop down menu? I thought they both had to be on
My battery is **** since 8.1, glad I found these options thanks to you guys.
I lose 20% battery life for 1 hr of SOT, super bad. I'll let you know if it improves.
