[Q] Still chasing battery drain: Is it possible FingerPrint Unlock is part of it?

So having come from Verizon's Note 4 and averaging up to 24hrs on battery running pretty much the same setup as I do now on my T-Mobile Note 4 minus the "Root" & "Custom Rom" abilities. Otherwise, same apps, accounts, usage pattern, ect...
I am on an ongoing battle still after several complete wipes, different Roms including just running STOCK ANK4 and trying to figure out what is going on. Phone defect? Battery defect?
Anyhow, Ever since changing over to both the T-Mobile Note 4 & their service, my experience has been a rather miserable 14 to 18hrs MAX battery life and going from 4hrs screen on time to around 2 1/2 w/ T-Mobile.
Which now leads me yet to wonder something else. I believe I started using the "FingerPrint" security feature since switching to T-Mobile to unlock the device. Has anyone experienced a similar "Battery longevity" issue using said feature before I continue troubleshooting and chasing my own tail on this? Of course I will eventually test this theory anyhow, but figured I would throw it out there.
Also, Open to any suggestions.
Just some things I have already done along with the above mentioned:
- Utilized the App "Greenify" & donation full version to greenify many apps including "Google Play Services".
- Set up Profiles which I toggle via "PhoneWeaver" to turn off data when on Wi-Fi which consists of 90% of my day as I'm Wi-Fi connected both at home and work.
- Of course always turn off that option within Wi-Fi settings to untick "Always Scan".
- Went into "Google" app settings and turned off about everything I can find in there and it's now rather complex settings.
- Turned off most syncing of my 2 "Google" accounts to only one having anything other than Email Sync active such as the Calendar, Contacts, and Apps Sync. - Again, my 1 Google Account I only have set to sync Email and nothing else.
Sure I forgot some things I've tried but again, I am open to any/all suggestions. I admit, I bought my T-Mobile via Swappa. All seemed well as per their checklist of the obvious things to check regarding the phone's operation. Kind of stuck here now and wondering if my device is simply defective and/or the battery.
Also of note: Android System is always by far the largest contributor to my battery drain and exceeds even Screen-On time by around 10%. But then again, don't really know if that means anything or not since even before switching carriers and the transition from "JellyBean" to "KitKat" on my previous S4, Android System became a forever battery hog for me.
Just never had a top end device such as this in past years barely get me through a complete day: Work & Home time. I don't consider myself a heavy user. Barely even "Moderate" many days as I mainly text during my lunch break, otherwise phone is pretty much idle. And say 2 phone calls of aprox 20 min.s each during commute time. Yea, something just isn't right. :crying:

I have noticed 3 things that were hurting battery bad.
1.) Use the Google play services with the 030 extension. I get way better battery life on it 5% to 10% increase in battery life. Link below:
http://www.apkmirror.com/apk/google...ices-7-0-99-1809214-030-android-apk-download/
2.) If you are not using maps or other location services turn your location off. Literally a 20%+ increase in battery from this alone.
3.) Toggle your NFC. Something in Android 4.4.4 sometimes causes your NFC to wake lock. If you turn it on then turn it off one time it normally fixes is.
I attached my battery stats below.
It with about 2 hours of screen on time.

Thanks for the reply and suggestions! I just checked and I am currently running Google Play Services V 7.0.97 (1791429-030).
A couple things I have done meanwhile since my OP which have had "some" noticeable positive effects on my battery duration, yet still no where near what you have posted are:
Within "Google Settings" app:
- Account History ( I have "turned off or rather paused" ALL the Activity/Info/History settings here - All 5)
Regarding my 2nd, basically "Junk mail" Gmail Account:
- Now have ALL "Sync" turned off within, including the syncing of email, which I now simply check manually to update.
Greenify:
- Revisited, and added a bunch more apps and pretty much "Greenified" ALL Samsung related entries/services/ect...
So far I have increased to achieving up to about 3 1/2 hrs Screen time (Gained 1 hr) & a few more hours of real time battery longevity as I can now achieve close to 20hrs before needing charge.
Still feel I have some troubleshooting to go. Oh, I actually have the NFC Service "Greenified" to. So far haven't really noticed a problem with "Deep Sleep" either according to CPU SPY pro.
Yep, Have always had the Location Service to OFF, not even using the so called "Battery saving" selection with it. Such a pity to have to cripple such things but it's a trade off I guess in achieving a full day's battery vs.s using the features with this phone for some reason more-so than past devices it seems. At least in my case. :silly:

Horrible Note 4 Battery Life. Android System Draining Way Too Much Battery.

So I have a T-Mobile Samsung Galaxy Note 4, I got it back in October so yes I have "broken in" the battery. I have checked out several other posts and tried pretty much everything. I've turned off bluetooth, NFC, any and pretty much all useless Samsung features (smart stay, turn over to mute, multi-window), I've got a black wallpaper on for both my home and lock screens, I have greenify AND DU Battery Saver, I ONLY ever use data as I have unlimited data and my building has a shared wifi network which I don't trust, I have tweaked Sync in the settings menu to only sync crucial info from all my accounts (google, facebook, email, whatsapp, etc.). So far the BIGGEST battery drainer is Android System. It is always number one. I've had days where I've decided to push the screen-on time to its limits and have used it nonstop. Screen consumption only ever gets close even if I use my phone nonstop Android System is the biggest offender. I've tried keeping power saving mode on 24/7 but that has not seemed to help at all. I've disabled S Health, S Voice, and several other apps I never use like Google Play Newsstand. I am at the end of my rope I despise this phone for its claim to great battery life but its absolute GARBAGE real world performance. I consider myself lucky to get over 3.5 hours SOT. At this rate I might as well have an iPhone 5. I have no idea what to do.
Here's a list summarizing the things I've done to improve battery life:
Bluetooth off
NFC off
Multi-Window off
All email sync set to Manual
Sync for every account adjusted to isync only crucial info
Pitch Black Wallpaper
Power Saving Mode (Not Ultra Power Saving) switched on about 90% of the time
Using Greenify on all Power-Hungry apps
Closing most apps upon finishing using them
Using DU Battery Saver in order to monitor battery activity
Never use Wifi
No Multi-Window
No Touch Sensitivity
No Side Key Panel
Wifi Calling feature disabled (I never use wifi anyway)
No Download Booster
No Smart Stay
Animations switched off via the Developer Options
Tried using another battery (similar if not identical results)
I'm still getting at the very best if I'm somehow on a miraculous streak of good luck that day: 4 hours of Screen-On Time. It is ALWAYS Android System usually followed by Android OS and then an app or two before Screen (because my SOT is so pathetically terrible)
I love this phone, the display is beautiful, the camera is fantastic, it runs seamlessly (on Nova Launcher that is), BUT I despise the battery life. It has made me resent this phone and I'm seriously considering switching to the iPhone 6 Plus as that has comparable battery life and with it running iOS I doubt the OS would destroy my battery the way Android has been lately. What do you guys do to get such good battery life from this phone? I've tried everything I know!! Please can you help guys?
I'm also attaching screenshots from one of the BETTER days.

I would consider rooting and installing a custom rom, poprock I would recommend for keeping touchwiz.
I don't know.. maybe your battery is the problem.. When I was on stock I had the same issue, but i varied in a weird way. With poprock, battery life has been amazing.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

I'd already seen your thread. It wasn't too helpful for me unfortunately because I'm not rooted. Half the terms you guys were using "Odin'd, pit file, etc." I don't understand at all. I'm running Nova Launcher on this phone. Just typing this comment my battery has dipped from 78% to 74% this is ****ing ridiculous I'm sick of this **** phone I might just switch to iPhone. I'm done with battery raping Android.

I'm in the process of fixing this. I think I may have figured something out. I have been slowly working through freezing applications to figure out what is causing the battery drain. I've made some progress. I really think it is an issue with lollipop system apps.
I am now having a slight dragon from cell standby, but the Android System drain is getting capped. Been in this single charge for 17 hrs and Android system is only 7%
Once I get a bit more firm information I will post my findings.

Some suggestions: check out your Google settings first. Disable Google Now and uncheck their location monitoring settings. Also freeze Facebook (use the website instead). Finally ou can disable sync altogether for a while in case other apps are hammering away through it. Test your battery under each of those conditions. Good luck, be patient, take your time. If your battery is good eventually you'll get to the bottom of it. Use Better Battery Stats to monitor. Most people get fantastic battery life. I rarely use 40% in a day. Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Thanks I'll try some of that but my problem is that I shouldn't have to do all of this crap! God it seems like we HAVE to revert these superphones back to pre 2000 dumb phones in order to get any kind of a decent battery performance from them. Samsung just haaaaaad to make the screen 2K. If they'd kept 1080p it might've been better! I might as well just switch to the iPhone 6 plus if I want ZERO functionality from my big screen phone. God I hate this Note 4 and I'm so jealous of people who don't do anything like this and still get 5-7 hours of SOT with their Note 4's. I'm beginning to think they're full of it honestly.

Nope. Either replace the phone or wipe and start over since u not rooted very little help.

If you're not rooted do this:

If you are scared of root just stay stock rooted. Not a slight at Bacardi. He answers the questions better than us.

I am have the same issue with battery drain from Android System. I have see that issues is there when WiFi is enable the battery drains faster. When WiFi is off and using mobile data it drains normal.

Battery drain - at&t note 9

Hi guys,
Have been using my new note 9 after replacing it with my s8+. So far it's a pretty good phone. One of the primary reasons for me to get was the large battery such that it will last m even more longer. But I have been noticing poor performance everyday. At the end of the day, I am bleeding to 10%. The s8+ was given to my wife and I compared her usage vs mine and for same amount of screen time I ended up at 30% and she was at 67%. I have less amount of apps installed than hers and she is heavy user of all social media apps. I have been observing my battery performance and what seems to be draining the most is the Android system, Google play services and Android OS. They claim all together half of my battery life. I noticed that there was an update right after I setup my note 9 initially and not sure if that could have caused it. Is there any way I can reverse it to see if it was the update? I have already tried wiping out the cache and shutting down all background activities on those items and blocked notification on pretty much most of the apps. How is everyone else's experience on the battery? I forgot to capture screen shot but will do it at the end of today.

I'm chiming in because I'm currently using the Note 9 ATT variant. My battery life has been pretty decent, but it's tough because the usage and even my "all day" and your "all day" can differ so much. Are you using 1080 resolution or did you set it to the higher resolution? I'm also running the ATT update you mentioned. But I'm also using wifi calling, not sure if that hurts or helps battery life, I haven't used it on my previous unlocked international HTC devices, so I'm just starting to experiment.
Have you enabled any of the battery optimization?
You can go to settings/device maintenance and click on battery on the bottom. I have it set to off in the "presets" but at the lower part of the page you can see "app power monitor" and see the app's power usage per hour. If you've got some that are higher, you can click on just those apps to check them on the list, and then click "save power" and see if your battery life gets better.
Possibly if you're using always on display you can modify that, if it's not something you really need and have already addressed.

Thanks for your reply. I am not running any battery optimization. I wanted to try default. Yes, I looked at battery usage per app and don't find anything bothering or consuming extra battery. Resolution is set to 1080 and always on display is off. Also. Wifi calling is on at all times. I am not sure if I am expecting too much but after using s8+ for over a year I was expecting much decent battery life with less than half of the apps installed on s8+ and having a bigger battery on this beast. I will need to find out how to lower down those Android system, os and Google play services.

My device is unlocked but on AT&T's network and I'm running my screen at max resolution and close to max brightness. My screen and AOD are always one and two with the O/S running a distant third or fourth sometimes fifth. If Google Play Services is consuming that much battery it is constantly running in the background trying to sync or pull data which it's not getting. Focus on that application and you should be fine, my phone is typically at greater than 50% at the end of the day and I use it all the time.

How do you find which app or service is running in background which is trying to pull or sync data?

Just a note, I had to drop t-mobile to make a point with them for screwing with my account. Houston has good coverage but the network is congested and that is an understatement. My battery life went down on my V20 and my note4 when on ATT's network. Not that the reception was always poor, because it is very poor at my house, but speeds and latency on ATTs LTE were like going back to HSPA. Sometimes it was better to turn off LTE and just put up with the super high latency to get decent speeds on ATT.

Go into settings/apps/Google Play Services/Battery and see what it's been doing. You can restrict the app as well from there I believe, also clear the cache. As I stated I would focus on that app specifically.

My experience was rough when I first got the phone as well. I factory restored with Odin and used ADB to remove all the apps I was not going to use. I then i stalled all my apps and the battery life took a hit again. I'd come home from a 9 hour day of work and be in the 40s. I downloaded betterbatterystats and let it monitor my phone overnight. I found that com.att.iqi was running all the time and constantly causing wake locks. I downloaded package disabler pro and disabled that package. Now when I leave work I am at 75% battery for the past two days. By bed time my phone has been off the charger for 18 hours with about 4 hours screen on time and I'm between 25%-35% which is outstanding. I made a thread with my complaint comparing the battery to my iPhone X and was called a troll because android can do no wrong. In short get betterbatterystats and package disabler pro.

Thanks for this, I was wondering if betterbatterystats would work on my Note 9, but hadn't researched it yet. It's a great app specifically for targeting issues like this, but I've always used it on rooted devices so I didn't recall if it worked on unrooted devices. I'm looking forward to trying it over the next few days and slimming this thing down.

Try Wake lock detector lite. One simple adb command allows you see wakeup locks etc ..

My battery life on the ATT version has been garbage too. I was going to return it, but I missed my 14 day window. Thus far, my S9+ was a better device, but I'm hoping the little bugs get squashed in an upcoming update.

One thing I'm wondering about is Bixby. My battery life seems to be pretty decent with ATT. I don't use Bixby, although I haven't disabled the app, I don't have it set up or signed in.

I actually managed to return mine and got another note 9 thinking that I would try it without doing the first update. Unfortunately that software update thing popped up while I was using the phone and I hit continue by mistake. I am kind of thinking about returning this one and getting the s9 plus if I still have this crappy battery life.

I'm not a battery life hawk,but,there's a few things you can do without crippling your phone (some already mentioned) before throwing in the towel.
1) Go to each app in SETTINGS > APPS > MOBILE DATA & turn off ALLOW BACKGROUND DATA USAGE on apps that have this option & where you're absolutely sure this will not impact something important to your usage.
2) Package Disabler Pro was already mentioned,it's well worth the price of admission. This is where you'll likely see the biggest improvement,surely no one here uses every single feature/app on any phone,force stop & disable what you're not using.
3) Again,I'm not a battery stat ninja,I just use my phone as I see fit,but,others have suggested try using FHD instead of WQHD for screen resolution. I myself use WQHD,but,I'm content with my battery life,however,I'd give it a try if I felt the need.
4) If you have NFC on,turn it off until you need to use it,access to it is quick & easy. I myself do not use NFC,but,even if I did,I can't imagine I'd use it to the point to where I'd leave it on 24/7 for convenience of use.
What's important to your usage is in the eye of the beholder,so,that's the extent of my recommendations for battery recommendations. The few I've mentioned should net some improvement without negatively affecting your routine usage.

Yes. But it seems to stop working once the battery level reaches a certain point. I think it was somewhere below 80% , probably 60% . I installed it last night.

THX,gonna give it a go. :good:
I may drop the developer a line,since the app hasn't been updated in a while.
Perhaps there's been some changes in Android 8 that haven't been addressed.
Regardless,I'm gonna try it out.

I'm trying to ascertain which one to use. Apparently this app shows all wakelocks whereas better battery stats only shows partial wakelocks, from the small amount of research that I've done.
The dev apparently doesn't respond and has abandoned the app, again from research I've done

I am trying a rundown tomorrow with power save. Just CPU and screen brightness. I left resolution and network usage on. I don't think brightness does much. It is supposed to be -10% but I have trained my auto brightness some and I have been having to turn it up. So I think only speed limiter CPU 70% is at play.

Exynos Note 9 screen off battery drain (not entering deep sleep)

Hello!
I've owned a N960F for about 2 months now and recently I'm dealing with extremely high screen off battery drain. Looking at the stats offered by the battery tab in device care I am unable to pinpoint the cause.
Furthermore, accubattery shows very low deep sleep time. Last night it managed to achieve an incredible amount of deep sleep of 0 minutes and drain 12% in just 5h 20 minutes of screen off time.
Screen on time is not a problem, while using the phone the battery usage is normal and I am pleased by it's performance, but it is greatly affected by the screen of consumption.
Does anyone have an idea what might be causing the device to not enter deep sleep mode? Or how to find out what the problem could be that makes it use up so much juice?
Thanks in advance!
Screenshots (the accubattery is from yesterday, while the device care one I screenshot just now):

Difficult to tell, possibility is an app in the background preventing deep sleep.
When you use device care and then select battery, followed by settings you get a further screen of options, you may be aware of this.
I have used these settings, it might help.
An alternative approach is to uninstall an app to see if the phone then goes into deep sleep

I can't seem to pinpoint any app that could cause this problem and my settings were already as shown in your screenshots

i found a wierd bug recently. If you're google account has a sync error, like gmail, contacts, messages, ECT.. it will not enter deep sleep.
go to settings>accounts&backup>accounts> Google account>sync account>
Do you see anything with a circle formed by two arrows? those items can't snyc in the background for some reason. usually because the phone has put the app to sleep, optimized it, or restricted background data access. turns out my contacts arent syncing right now, glad i checked.
use this to try and help troubleshoot if you need help.

this might actually have been it, I found a weird Office account that was not syncing (I don't even remember adding it) and I removed it, I'll update if it has fixed the issue

jd14771 said:
for me, the problem was that my Contacts app was set to non-optimized ect ect... but the googlecontactsbackup app was set to optimized. I didn't even know that apps could have dependencies that show up as other apps. (i installed google contacts to replace samsung's people app).
i went from 1%-1.5% drain per hour, too .5% drain. significant change for me since im already heavily debloated.. thanks for making me look that deep lol. this is why people prefer iphones i suppose.

Are you debloat with adb and console?
Which apps disabled?
I think that Note 9 exynos have problem with consumming battery in sleep mode.
My N9 always "drain" 3-4 % in night after little debloat but A5 without debloat and with more apps consumming only 1-0% per night.

General (SOT) Leaderboard - post your longest SOT's here 👍🏻

Looking at the OnePlus 10 pro on paper, it has everything you would possibly need to achieve incredible screen on times.
The idea behind this besides some healthy competition is to whittle out the bugs and battery draining apps and habits.... in the hope that we all benefit from the knowledge learned and gathered.

Rules
---------
If you'd like to register an SOT, you will need to provide a screen shot of your battery stats using the stock battery app, clearly showing the up time and screen usage time and app list.
Your OS, kernel if different from stock (no screen shot required)
NOTE*** Without this proof, your name and score won't be added.
That's it
Good luck

Some tips for better battery life.
Change 5G to 4G
Remove Facebook use web based
Remove Facebook messenger use web based
Remove Twitter use web based
Remove any ad based apps pay for the pro version
Turn off gestures like lift to wake
Change from QHD to FHD (No difference)
Allow auto brightness
Turn off WiFi overnight
Turn all updates to manual not auto (play store)
Remove any so you don't use
Change back up to once a month (WhatsApp)
Turn off location history (Google)
Use titanium to remove any system apps you don't need
Don't allow anonymous usage statistics for any app ever.
Don't allow tracking cookies on any website
Use adaway (root needed)
Don't open web pages in Google app (I use Samsung browser)
Don't use xposed.
If you game you will not get high SOT scores, period.
Don't bother with battery saving apps or monitoring apps.
Streamline your apps, if you don't use it, remove it.
Don't allow WiFi scanning (as in letting other apps use it when it's not on)
Never allow personalised ads.
Never allow notifications from websites
Always decline cookies unless your absolutely have to allow some tracking (common sense prevails here)
Optimise as many apps as possible unless it affects performance.
Don't allow apps to remain open in the notification area.
Change your launcher, my preferred launcher is lawn chair and this did actually burn up some battery when compared to the OnePlus launcher.
Don't use live widgets (yes they look cool, but they annihilate your battery)
Live wallpaper, again very cool, but battery burners.
Again! Don't charge overnight, make a note of your percentage then see what it is in the morning, you shouldn't be losing more than 5% really, if you've done well then it'll be reflected here, the good SOT results will follow.
Turn off live read outs of network speed, RAM usage in the status bar.
Turn off NFC unless in use.
Leave location on in quick settings.
Don't overcharge your phone, IE: overnight
Don't allow your phone to fully deplete the battery.
Whatever anyone says, this does 100% damage batteries, there is no argument here and I won't entertain anyone who says otherwise, Ive seen through real life tests what this results in, bloated, inefficient, possibly dangerous lithium batteries.
Keep your phone out the sun.
Keep it out of extreme cold.
Keep your device clean and dust free.
Snapchat, Viber, house party, apps like that tend to use more battery as they don't have great dormancy periods, use them if required and get rid.
Apps like speed test by Ookla tend to have location tracking, similarly they tend to turn themselves on and off when they feel like it, my advice, install test and uninstall.
Allow a couple of battery cycles between tweaking sets, to give you an idea of how much of a difference you've made.
Use BBS to see what is being used, once you've removed problems, remove BBS.
I've just written this from the top of my head so I've probably missed some things, the general idea is to keep your device clean and fresh, remove files / apps / mods / widgets / features you don't need any more.
Keep an eye on apps that misbehave or aren't wanted, index your folders so they aren't a mess.
The more good things you do means the more potentially bad apps you can have on your phone, eg if you really need Facebook, you could keep it so long as you clean up other areas of your phone.
Hope this helps.

I'll put it up as there's none up and a believable time.

Changed over to lawnchair 2 and holy moly the difference has been amazing.
0% lost overnight 8 hours
Currently on 4 hours with normal usage, it's heading for a ridiculous screen on time.

6 hours and 2 minutes with 41% used.
Crazy

Not that I've noticed.. its just the one from the play store. I think it's 2. Could be wrong, certainly more efficient than anything else I've tried.
I'm just happy I've managed to get my phone to be dropping 0% overnight, that's how it should be.
My 8 pro used to take about 4-8% overnight

Gonna try out Lawnchair launcher and see if it helps my phone too
Most recently I now have 8 hours SOT with 12% battery left. Feels good gonna try to empty the battery to 1-2% and report back the SOT here once again.

I got 2 % drain overnight 8 hours, which is ok for me with everything I got installed (airplane mode).
I wonder whether I will try lawnchair too, but I am using Nova for years

Comparing the two I prefer lawnchair, nova is a little too flicky for my liking, I prefer smooth transitions and fluidity rather than overly quick and flicky, you'll know what I mean when you install it 2% is still 2-6% better than the 8 pro..

Tbh that's still great time you're making.

It's nuts I'm on 7+ hours with 52% left.
Haven't been doing anything special, just using my phone.

Try disabling Google play Services when not needed. It has a bunch of power sucking dependencies. I disable more Google system apps than that on my N10+, but disabling play services may be enough to tone it down especially at night.
Use manual brightness control and keep below 50%.
Social media apps should never be installed for a variety of reasons including excessive battery consumption... just saying.

I agree buddy, but I'm not sure I need to disable anything else.... At this rate I'll have 14 hours SOT..
Have a look at the second post for my idea of keeping the battery down
But then again, could always have more...
So when you disable Google play services. What method are you using?

Just literally disable it?

Agreed, it sounds optimized to me! Hell yeah.
Most Android phones need to be optimized to get best performance... just the way it is.
I go to settings>apps, search for play, then disable/enable it there. I use it 2-3 [email protected] day, sometimes less.
If the disable option is grayed out, go to security and disable Find my Device as a system Administrator.
So many big sister Gookill system apps I hate...

Just done it but getting a lot of dings every time I unlock, little annoying tbh. I'm just wondering is the call to open services actually using battery ? I dunno. Perhaps if there wasn't a load of notifications..
I'll leave it for this cycle and maybe see how it compares next time, I'm not out over the weekend so have a good location to get fault results.

On my phone it can suck up to 1+%@hr with screen on... so it adds up. No reasoning with it.
You can kill those very annoying notifications; Gmaps, Gmail, do it; disable notifications. There may be more depending on your configuration.
Leave the warning running and when you disable notifications in the right app... it will stop. Instant gratification
