[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 life tips/tweaks to stop battery drain

When I first got the Note 5 last week, I noticed the battery life wasn't so great. After making some tweaks I've noticed that 1) Android system isn't the number one thing eating up my battery 2) Cell standby isn't consuming more battery than my screen anymore and 3) Screen is the number one thing consuming battery and I'm getting fantastic screen on time. The first attached pic shows stats from my phone being off the charger for almost 8 hours and I was connected to my wireless earbuds via bluetooth and streaming pandora for almost 4 hours while traveling to and from the gym and during my workout (all over the network, no wifi but when I'm home or in the office, I'm always on wifi) plus I had about 1 1/2 hours of SOT. The Second pic is day 2 with 1 day and 2 hours of use with 37% still left and 3 hours of SOT. Also, I have Google Now running, Facebook, Instagram and Twitter constantly running and I maybe lose 1% battery life every hour or longer when I'm not using the phone.. I'd like to thank @rlsroufe for his debloat list because that was a big starting point.. Here's what I did:
-Disable AT&T/Samsung Bloat (Package Disabler Pro)
-Disable S Finder (Package Disabler Pro)
-Turn off motion Gestures
-Turn off S voice
-Turn off or decrease vibrations
-Turn off Google Location History (Huge battery drain, causes play service and/or Android system to go nuts)
-Turn off Android Device manager (Lock Screen and Security —> Device Admin)(Also causes play service drain)
-Disable Unnecessary Sync Service
-If you use Adguard, turn it off when you don't actually need it and just flip the switch when you do
-Turn off S pen Alerts, pen detection, and S pen sound and vibration (will still work exactly the same)
-Turn off Enhance4GLTE (basically voice over LTE, makes cell standby consume a lot of battery)
-Turn off 'Always allow scanning' under advanced wifi settings (Allows apps to serach for Wifi even when wifi is off)
Reboot and enjoy..

I think it was sarcasm.
I had posted this in another thread, but using package disabler to disable "s-finder" seemed to have made a large difference in battery for me. I (personally) usually keep location services and android device manager active, however.
One thing common with many android phones is that for the first couple of days after you first get the phone (or factory reset it), location services tends to draw more power when compared to after you've had it a while. I have nothing to confirm this (and I've been too lazy to try and verify it), but I suspect that location services keeps a cache of cell phone tower locations... so the drain would be higher while its still building up that cache.

Yeah I feel like disabling S finder helped as well.. I consider that samsung bloat as well but I'll add that to the list, thanks. I keep location service on as well but I turn off location history which is what I think was causing stuff to go nuts and def noticed a difference right away. Device manager I don't really use because I noticed if you factory reset your phone via the phone recovery, you still have to sign into your google account before you can do anything with it so that's nice.
Yeah that sounds like a logical theory and could very well be what was draining battery. But literally 2 hours after turning off Enhance4gLTE, cell standby dropped and noticed battery life was a lot better. There's been a few threads on that as well as VoLTE (tmo equivalent) that suggest that's the issue for drain as well.

Can you share your disabled list in Package Disabler Pro please?

Got this via @rlsroufe and @mcdavid
FYI - There's an Extreme (left column) and Basic (right column), I just went with the Basic one. Green Means I left it alone, Orange means I disabled it and Yellow means you can but don't have to. This is for the Tmo variant so some things wont be on this list so I just went one by one and did it just by typing in the last word of the application. Anything that I actually used I left alone but you can mix and match if you want and see what works best for you.

Okay.. So Samsung made this SUPER ambiguous.. But the "Disable Pen Detection" setting.. Are you saying that that toggle needs to be ON or OFF? What does the setting do anyways? I can't understand Samsung's wording in the settings..

Lol yeah, there was a big discussion in anther thread about that. Putting it in the 'Off' position turns it off which is what you want.. I believe it just turns off the feature when you walk away from your s pen and it warns you.. I could be wrong tho but since doing it, nothing has changed with the S pen and it all works the same exact way when I pull the s pen out

Haha, I think there's a setting for what you described (other than pen detection) but have you noticed the battery life is better when that setting is turned off? Or is it not noticeable?

I'm not 100% sure because I did everything pretty much at once. It does say it might help save battery so that was enough for me. Everything has been working great so far tho, finished charging my phone around 12 today, left it for 2 1/2 hours and didn't lose a percent even tho FB, Email, App update and Text messages were coming in so I think it's a combination of everything

Actually leaving it in on position turns off pen detection which saves battery. I am rooted, checked with SQL editor.

So what is the verdict? Off or on?

LOL says in my settings for this "turning off pen detection when the pen is attached can extend battery life".
So i turned mine OFF

My secret is leaving it charging all day, all night, all day etc. That's the only way.
Sent from my SAMSUNG-SM-N920A using XDA Free mobile app

Based on rlsroufe's SQL dump, the option should be ON which disables pen detection.
When you pull the pen out and the phone no longer 'sees' it, it uses the motion detector to see if you are walking away. If you go like 12 steps you get an alert.
Turning this option ON, disables this detection when the pen is attached to the phone.

Hey @oka1 can you please close this thread or disable the comments. I will no longer be supporting it because I no longer have this phone. Thank you

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!!

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.

Android Deep Sleep app?

I am testing a faulty app that it's being faulty during deep sleep, therefore to fasten testing I would need an app which can force the phone to enter deep sleep mode immediately.
Any idea?

As he said naptime is the better option for this?

Thanks guys!

Try disabling all power management apps ie all the toggles in Device Care are toggled off except fast charging.
Do not enable sleep for any; Developer options>stand by apps, all buckets should show as active if not power management is active.
Close apps when done with them especially ones like Brave.
The phone will automatically go into a deep sleep state at screen off unless a 3rd party apk is misbehaving.
On my 10+ running on Pie this is how it runs best and gets the best battery life.
Goggle Play Services, Gmail, Playstore, Google Backup Transport, Google Framework and Samsung cloud backup are prime offenders*.
Disable these and all Google, Samsung, carrier and apk feedback. I use Karma Firewall to find rogue apks and lock the phone down as well as a package blocker.
I also use Battery Tracker from the Galaxy Store.
Nominal battery usage is 7-10%@hour heavy usage like vids and surfing. Off screen usage with AOD on is 1%@hour.
*enable when and as needed

Try Naptime and what blackhawk says!

You'll need to play with it; what works with my configuration may not work for others.
These are my current observations. My stock AT&T 10+ variant is heavy modified and watched over. As I intend to continue to use the current Pie firmware, I continue to tweak it.
What I've observed though over the last year to my dismay is any power management interferes with functionality sometimes randomly and unpredictably. It actually ends up increasing battery usage within a few days although initially it may seem to improve it.
Apparently it causes system conflicts.
I have no power management active other than the screen is set to "optimize" in Device Care and even Device Care is package blocked then unless I wish to use it to clear the cache (which the factory load version does very well).
I toggle Google Play Services/Gmail on as needed and a few other battery hogs. Point is I know their status; no random shutdowns or apk failures... and the best battery life I've ever seen on this device.
You need to go explore, find the resource hogs one by one and find a way to tone them down.
All the shotgun get it done power management apks failed miserably for myself multiple times....
Android runs very well by its self once your rein in a couple problem apks.
Many times the factory loaded versions run better then their updated versions. Gmail, Gmaps, Device Care... may or may not be true on your load; trust nothing!

I also use Battery Tracker from the Galaxy Store.
Nominal battery usage is 7-10%@hour heavy usage like vids and surfing. Off screen usage with AOD on is 1%@hour.

When I go into standby mode in developers options each app has 3 options. Frequent, rate, working set. What should I put them on?
Also what exactly does standby mode do? Is it manually disabling that app while not in use or only when you close it? As far as closing the apps, will closing them via the recent apps screen suffice or do I need to force close them?
And my last question is what do you mean by disabling an app such as play services?

It shows the app's bucket state when power management is enabled.
Your power management is enabled... and likely wasting battery even though it's suppose to do the opposite. If power management is disabled as I suggested, all buckets are locked to active.
Right now I have GPS enabled; I disable Device Health Services com as it was constantly accessing the internet.
Usually closing the app is all that's needed.
Use Karma Firewall and Battery Tracker to help ferret out bad apps.
Depending on your model, OS/firmware load, 3rd party apks and settings configuration your system may respond differently.
I have heavily modified them on this 10+ Pie variant; it's an ongoing process. I have around 88 apks packaged disabled as well.

Samsung Galaxy S20 - Fast Battery Drain..

Hello.
I bought my S20 few days a go, with device everything is great but, my battery is terrible,
I use it every half hour to see do i have new notifications, messages, new posts on instagram and thats it.
I dont play android games or etc.
But with this minimal usage im losing 50% of battery @ work, and i use phone max 1h SOT in 7h of work time.
I tried Naptime but naptime only save my battery when phone is locked, but when im using phone im losing % very very fast.
My settings: Location , bluetooth, NFC disabled. Facebook in hibernation, and i disabled all bloatware with ADB uninstall.
And im using 120hz.
Normally with my settings on other phones i get very good battery life.
I do not want to root my phone, but is there any solution how to get more battery life on S20?
Thanks

Disable all power management except the screen setting which should be set to Optimize.
Disable all cloud apps, all device feedback, Google Transport, Goggle Transport Framework and Playstore. All autoupdates.
See my other posts on this ( good luck with that).
A package blocker is more effective for troubleshooting on the fly. I'm running Pie and Q gives you less tools to see what's going on.
Karma Firewall* is useful to lockdown Goggle Play Services* (a known serial offender) and others.
Nonetheless you need to find the troublemakers as you're burning up the battery.
Play with it... this may take a while.
*you lose its logging ability with Q I believe. A major hit if so.
**toggle on/off as needed.

I looked up every aplication, service and everything is ok, maybe device need to adapt to my usage.
*Device is 2 days old*
But, i did not fully discharged battery on my first use. Can that be the problem?
I know i had to do it but i forgot that.

I had S10+ before this device.
Im using same settings and apps. But difference in battery life is big.

Unfortunately you'll need to track it down; no one size fits all. You need to figure out which system and 3rd party apks are responsible.
Use what tools are available and ones you can find for that OS.
Even with all syncing disabled on my 10+ Goggle Play Services relentlessly connects 4 times a minute with the internet. Blocking it toned it's battery usage down.
Brave browser is a hog and will run in the background unless forced stopped; closing its window does nothing.
Fun times... Google did nothing to address this and in fact has been making troubleshooting harder with each new OS using security as a ploy.
I ran Kitkat until last year. In 6 years I've never been forced to reload due to malware... bite me Google. Yeah viruses, trojans, etc are real and can/do infect Androids but almost always it's the user's fault. Transparency is what's needed not scoped storage and more user/apk inaccessibility.

Let it settle in for a week. You shouldn't need to disable any packages to get good battery . My s20 gets 6.5-7hr sot without disabling anything and just using the 120HZ medium power saving Bixby routine trick , 5.5-6 hrs on optimized . Don't listen to those who say you have to disable a **** ton of stuff and basically cripple your phone...you absolutely don't .

Depends on the device, the firmware and what's loaded including carrier and Sammy junk.
I've tried it every which way and now have about 86 apks blocked. Some like Playstore and Galaxy updates get toggle on as needed which isn't often.
Every time with power management when it was used it seemed to work but within a few days it became the problem with excessive power consumption.
Plus and even worse it will screw up phone functionality constantly and inexplicably at times.
Android will manage power and go into deep sleep with all buckets active; no power management needed... at least on my configuration.
Because of the time and trouble invested as well as trash features like scoped storage I refuse to go to Q. This 10+ will most likely run happily on Pie and many of its factory loaded google apks.
Yes updates can and will screw things up; update one or two at a time, observe.
Having a fast, stable, predictable system that runs well with good battery life and does what you want is all that really matters with Android.
Security is very rarely an issue even on ancient software if you aren't inept.
As is I'm ready to do a full reload if needed, be back and running in 2 hours and 99% fully configured by that day with bare minimal internet connection required.

My S20 (Exynos) battery life seems to have improved since the Android 11 / UI 3.0 update.
For sure it isn't perfect but : about 4h SOT and 25% left.

Disable all power management except for screen/power mode.
Android does nicely by its self.
The only thing you should have toogled on is fast charging if you use it. Try it.
Once you got it running well be very careful of updates especially firmware. At least wait a while to see if it blows up the phones of others using it.
