How I solved my battery drain problem!
Have you tried turning off 3G?
I also had this issue battery drain was huge. It started appearing suddenly one day. Its a very slow process to figure out the culprit. I did a step by step analysis.
1. Found out that battery drain was happening only when 3G was on. Verified this by switching off data network (long press power button to deactivate).
2. Also verified abnormal data usage in my carrier page when I was not using my phone [like - 3G was on and I was watching a movie at a theater].
3. I also saw abnormal battery drain soon after I started Google Maps after a fresh reboot.
4. So I identified the culprit - Google Maps - but was not sure how to solve battery drain [Google Maps restarts, if you kill it].
5. I installed a variety of apps to identify the battery hog. Finally I went for Task Identifier.
6. Task Identifier finally showed me what programs started while my screen was off, etc. And I started noting them. Finally I figured out that Google Maps::BackgroundFriendService was running frequently.
7. A quick search on Google helped me understand that this is about Google Latitude. It searches for your friend's location every now and then - leading to battery drain!!!
8. I opened up Latitude and signed out from it [I guess the sign out option is in Menu -> Privacy].
9. Do not re-open Google Latitude after this - you will get signed in again leading to battery drain.
10. After 2-3 months of search and prodding, I finally figured out the cause of battery drain and fixed it - now I get 2 - 3 days of charge in my battery under normal usage!!
I'm happy now!!

Hi,
If you're using Froyo and can access file in your phone,
In task manager , on the tab "Summary", click on the "start monitoring" button. Let it monitor the phone over the night. The next morning, there should be 2 files created in your sdcard, one is CPUxxxxx and the other one is battxxxxxx.
The Batxxx tells you when the percentage of the battery at certain time of time. the CPUxxxx will tell you wht applications are running during that period.
When i used it first time, i notice that facebook and lattitude always running - when I stop these 2 tasks; i get a normal drain again.

while you guys are at it.
here's my "problem".
when I surf for an hour over 2g I losing about 10% batterylife and android reports that my display uses around 90% to 95% of the battery.
display is set to lowest brightness + screen filter.
is that normal? (im guessing it is not).
used dozens of different roms (stock, darky, jims, etc...), same behaviour everywhere.
i already did all the battery stat wiping and whatnot.
is it a faulty battery or display or something?

for the OP, maybe a combination of the above with this could help :

i have the same problem too after upgrading to Froyo 2.2.....what i do was turning the data connection off yand you will get 2 days with moderate usage....but oneday i had overcharged my phone (about 8 hours i think) and after that my phone can stay about a day and half with moderate use......btw i already did the 8 hours charge during my first charge long time ago.!...hope this helping

Google Now and Battery Drain

It seems Google Now is draining my battery, not really bad, but it is keep my phone awake.
Now, I guess this is just part and parcel of Google Now having to constantly check your location, but has anybody else have an issue with Google Now on the One?
My battery lasted me 12hours yday with what I consider to be heavy use. Bluetooth Streaming Music for 2hrs web surfing over 3G for 2hrs whilst on the train with varying 3G signal, web surfing over wifi for 1hr (including downloading around 6 - 7mb. 15mins of calls. Around 40 whatsapp messages received and read, about 20 emails received via gmail and read, archived. Couple of minutes video, Switching Screen on just so I can see the phone I say at least four to five times and hour.
Not very scientific, sorry didn't really capture any screen shots with BetterBatteryStat, but gives you a rough idea what the usage was, all of that with Google Now on which I assume is constantly checking my position.
I would like to leave Google Now on, but if its going to make a big difference, then I have no choice but to switch it off. I continue to have location services on, but I assume that just allows apps to use it when required. Is there anything else from Google that requires constant checking of location?

Ok, usual suspects.. switched of location reporting under latitude and the partial awakes for the NetworkLocation seems to have more or less disappeared. Hopefully I get a couple more hours with the sort of use described above. If that's the case, I'm happy with that!
Note, location services under settings is still on.

How are you getting that kind of battery life?! Check out my posts in the 'battery life' thead in the 'general' section. 12h is exactly what I'm looking for but I am getting like 9h

Well, as you know it's all depends on what you run and how you use it. So I can't really answer your question. I can tell you what apps I used though, I unplugged my phone at 7:30am and used Play Movies for a few mins, playing a video, used Gallery for a few mins, check train times using National Rail Enquiries app, used Chrome for browsing on 3G, bluetooth streaming music for 1hr on my commute into work. Used Chrome for browsing and Sky News app on WiFi for say 30mins... downloaded some files over wifi and 3G. 10 - 15 pushed emails, 40 odd whatsapp messages which involved downloading some images, blinkfeed updates probably 3 -4 times, maybe more.
10 - 15mins worth of calls and lots of switch on screen and going through some settings and homescreen navigation and Play Store navigation.
Then browsing over 3G and BT music streaming for another hour on the commute back home.
BT and WiFi was on all day.
I had Google Now on, location settings on, latitude on and the phone was at 2% around 7:30pm when I plugged it back in.
Not very scientific but hopefully you can tell if you use more power hungry apps than I do.
Then recently downloaded BetterBatteryStat and GSamBatteryMonitor and realised that Maps was keep my phone aware for not excessive periods, but throughout the day, I say about 1.5hours. So I looked into exactly what that was and it turned out to be Location Settings in Latitude and potentially google now. Set both of those off and kept location settings on under the main settings, so apps can use it on request.
The phone is now spending less time awake when screen off. There is also a Facebook refresh interval setting, I don't exactly know what that is, but that was set to every 30mins. So I have changed that to every 4hrs. Notifications from Facebook are still pushed I think.
One thing I have set is Blinkfeed to auto te on wifi only and not wifi and mobile data and that was set when I got the phone.
Being a new phone I'm using this more than I would normally, so I'm more than happy with the results. To me, the above is me using it a lot, some people may say that's actually moderate use... so it's all subjective.
Battery life is one those things where you just won't get the same result for everyone, it really depends on so many factors, so you may have done so already and you probably know exactly what you're doing (I haven't read your post unfortunately, meant to be working at the mo) but all I can say, is install those two apps I've mentioned and have a look at partial wake locks and go from there.
Hope that helps.

You can turn off use WiFi and cellular to help reduce the wakelocks or disable Google now. I never use now and it was always a horrible battery drain for me.

Do you have the App Google Settings. It came with the phone and it has a green icon. Go in there and under Maps & Latitude you'll see a load of settings.
1) Switch off Location reporting, I used "Do not update your location", however, I think you can use "Set your location".
2) I've unchecked Report from this Device.
3) Enable Location Sharing was unchecked for me by default.
4) Disable location history
5) Disable Automatic Check Ins
I also have google+ off.
Now, obviously if you like to use that stuff, then you have no choice, but I don't need to keep track of where Ive been and I don't need constant reminders about things around me and how long it takes to get home on public transport (which only includes buses btw). If I did need local information, there is plenty of other apps that does that at my request.
If they refined it and made it much more configurable then it might be good, e.g. include trains and actually let me configure when the times I want it to start checking, e.g. when I finish work, an hour before start looking at weather, train times home, any delays and whats on TV.. now that would be brilliant, one it will save power as it will only check location at specific times and two it's actually useful information at that particular time.
Thats me though. Others might need Google Now as it is..
Hope that helps.

I'm no expert, but that seems OK to me.

Google Now was an even bigger drain on my S3 ...I had to disable it on that phone. I was struggling to get past 6 hours! I deactivated all the Google Now cards and the battery life returned. The One is clearly better because even with those same cards enabled, I can easily get through the day and beyond. Google Now is clever, but power hungry.

Next thing to look at is the App Sucker in GSamBattery Monitor and set it View Time Held Awake. My top three are Kernal (Android OS) 38m 1s, Google Services 13m 37s and System (*wakelock*) at 10m 9s.
You can find a lot of info in there and you can drill down even further and usually can tell what exactly is it that's draining the batt. Kernal and System, I don't know enough about, but when there's specific Apps that show high battery consumption you can tell straight away.
E.g. yday, I started up Sky Go even though I knew it wasn't working and shut it down immediately. However, it continued to run in the background and could only tell by looking at the BetterBatteryStats and GSamBattery Monitor.

Concentrate on the top 2 mate, seems like Maps and MediaServer what ever that is keep your phone awake for over 30mins. I would set a custom ref and switch screen off and check again say 10mins.
I've also discovered something else in Kernel Wakelock. Im on wifi at home and after 5 mins of screen off, it nearly has 1min of MSM_HSIC_HOST wakelock. I think this is the modem and wonder why it needs to wakeup as all data is going via wifi. Since unplugged this is at 1hr 17mins, with only roughly 1hr away from home. Does anybody know if this sounds right?
It is something else to look into

Android system draining battery

I'm not sure what's considered high android system but mine is at 29% and looks like it's taking a toll on my battery. When I check the battery usage it's the highest thing listed. How can I lower this or fix this? Any help is greatly appreciated! I love this phone!

same problem here ... android system is at 24% with 59 minutes of CPU usage while screen was about 20% with more than 2 hours of screen on time !?! Why system is killing the cpu so much ? ... TouchWiz !!! *SMH*

Give it a week or so to even out.

This could be any app that is pulling your location. Most pull through your location through google play services, part of the android system. Not defending touchwiz usage but most likely the fault lies elsewhere.

I dont think so my location its off and still takes 29%, maybe a kernel issue. I heard they did the update we just got cause battery draining issues. maybe not fixed 100%

I get the same thing and I made sure to turn off notifications and apps that "push" and set em all to manual. I use the same apps and settings on my S5, and LG G3 and would be able to get around 6 hour screen time and total of 17-20 hours per charge. AND on those devices, the screen is usually the highest % and the android system is not even near that %
Right now I'm getting almost about the same as my S5 battery life, maybe a bit shorter...

Same problem here, about 42% on a normal usage. I did not have this problem before, on stock Rom but since I switched to cynanogenmod, my phone can't make it through the day.
What's more, I'd like to know if any of you know an xposed module or an app which can automatically turn switches on/off when starting/closing an app. Like turning GPS on when starting Google Maps and turning it back off when closing the app, for instance.

I found this was related to location services and / or google now.
I found these worked for me:
1. Turning GPS location to GPS only (i.e. not using wifi). I believe this stops passive location tracking, which in turns stops the other services always running
2. Turning off location tracking / history. As above, no detailed location, no other fancy things running all the time.
3. Turning off Google Now.
I listed the above in the order I would do it. Using just item one, you still get most of Google Now's functionality.
End of the day, what I found was there was a lot of "smart" stuff going on in the background around your location, and this is what caused most of the CPU time. If you look at your wake locks, you will see it drop off dramatically once you do the above steps.
Some people have reported turning location services back on after a while didn't result in a spike in CPU time.
This isn't a Note 4 thing, more a Android / Google Now thing in my opinion,.
Hope it helps.

thanks for the advice and suggestions, but my s4 and s5 did not have the "android system" so high in usage. i've tried the turning off gps, then back on, and then restart phone thingy, but same results. i just hope sammy would address this issue as it seem pretty widespread.

Just to clarify,Ii suggest turning location to GPS only. And leaving it off.
Turn off location reporting and history also. Then see what results you get and go from there

Good to hear.
I found I can have GPS on without any issues, as long as either Google Now or location tracking was off.

Any more info ?

I am having the same issue in tandem with weak battery signal. Do I wait for Lollipop or do I just sell my N4 and get an S6?

[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:

Poor Battery Life - HELP!

So, over the last week, I have noticed such poor battery life. My battery is not performing as it once did.
I recently downloaded Power Shade, so I decided to disable it (not uninstall it). It's not listed in the Play Store at this time.
I have noticed that Android System uses a lot of my battery, while my battery life drops like a rock while I have my screen on. I never have my screen brightness passed 25% (and it is usually less).
Please take a look at these screenshots. What is going wrong?

It says your phone has been on the battery for over 15 hours.. I don't see how that's considered bad? That's pretty much what I get.

Install BBS, grant permissions and check what is messing your battery. That is awful SOT

Well, I turned on Power Shade and left my phone untouched for one hour. My battery dropped 5%.
Then, I turned it off and left my phone alone for another hour and it went down only 2%.
So, that's the culprit?

I'm not sure if your battery drain is regarding normal usage or standby time.
If it's a standby drain, I would suggest installing Naptime app from the playstore. Grant the permissions via ADB, your standby battery life would be great.
I've experienced a really good battery mileage after installing the app.
Make sure you enable to aggressive doze option and keep the app out of power save or the sleeping apps option.
Also, try turning off Location and see if Android System percentage goes down.

Is this tough to do?
I had Location set to "High Accuracy" - I have now changed that to "Battery Saving."
Better?

The naptime app is a piece of cake if you have root access, if your phone is not rooted, the app will suggest some steps you can follow to allow it function properly. For the non-root method, you will require a computer and ADB (Android Debug Bridge) to be installed in the computer.
If you kept location service to battery saving then maybe it might help save battery juice.

I think I will stick with the Location setting change.
I'm also finding TuneUp Master Pro to be helping.
What do you think of BetterBatteryStats?
Later today, I can post screenshots.
Right now, I am at 63% battery left with 2 hours of screen time. (Note, much of this has been with super low battery brightness.)

Do you have certain settings that you think I should really have (without any repercussions) that you could screenshot me?

What do you think of these settings?
About 7 hours were not on Wi-Fi...

Hey,
I think TuneUp Master Pro might help you, I haven't actually used BetterBatteryStats.
But I saw your screenshot, one thing I noticed is that you keep bluetooth switched on (Android Wear)?, If so then I think maybe that is your issue (I'm saying this cause I have a Gear 2 connected to my Note8, when the device is connected it takes some amount of battery). Try to use your device without bluetooth for maybe 1 day and see if there is any improvement in Battery Life and Screen On Time.
I would suggest other basic options like:
1. Turning off Location when you don't need it
2. Turning off Bluetooth
3. Turning off Mobile Data (or keeping the network mode to 3G/2G)
4. Delete useless apps, if you have apps like BetterBatterStats, I think they can monitor app data and battery usage.
5. Goto Settings>Device Maintenance>Battery, scroll down till the end and select "always sleeping apps", select apps that you want only to wake up when you open the apps. Go back and remove useless or unwanted apps under the unmonitored apps section (This option is right before the always sleeping apps one).
Also try doing a cache clear from Android Recovery (Be Careful when selecting the options):
1. Turn off your phone
2. Hold the Volume Up, Bixby and Power Button simultaneously until you see the boot screen, as soon as you see that screen release your fingers from the buttons
3. Once the recovery options come, use your volume buttons to move up and down, and the power button to select an option.
4. press volume down and select the clear cache option, press the power button, use the volume down button again to select "Yes" and press the power button.
5. It will clear Cache
6. Restart your, its the first option in the menu.
This might helps the phone clear cache files and maybe fix your battery issue.
It would also be good if you install this app, after installing goto the "Personal" tab and check if your battery health is good, mine is 91%. You should also be in that range or maybe 80%. If the percentage is bad then maybe I think you would require a battery replacement. Correct me if I am wrong guys, but just a suggestion.
One more thing, is your phone rooted or having a custom rom?, if yes I suggest to try Naptime and other rooted battery saving apps like Greenify.
If not then I think you and me will have to hope that Android 9.0 Pie would have some improvement, sadly I have been a Samsung user for 4 to 5 years, this isn't usually the case with Samsung OS updates .

Based on this, I don't think I have anything rogue going on, do you?
(Notice that I didn't use my phone at all during this time, nor did I leave home.)

OK, I have attached stats for my phone from today.
Please take a look.
When not using my phone, my battery only dropped about 2% per hour, which is great. But when my screen was on, I seemed to have lost a lot of power. I can't even get 4 hours of screen on time.
What would cause tis to happen? I barely have my screen brightness at 20%.

Does this tell you more? It shows battery usage with cell phone signal.
(I was off Wi-Fi for about the last 6 hours of the day.)
Does this show a slower battery drop with a better signal?

Chrome and facebook drain lot compared to others. Are you putting them (and others) to sleep using device management? Also, 2.7% drain per hour isn't fantastic. You can drop that to approx 1% if you tame enough things on your phone.

2% per hour for rooted phone is very bad. In 10 hours you loose 20% battery, looks very bad too. If you open the 4g you loose 40%. I loose 2% every 10 hours and i have 95% kernel deep sleep. Your System have big drain in first picture. Debloat your rom and fix your bad wakelocks with amplify and with appops. Possible change your rom and your kernel if you are not rooted. If you are not rooted god bless you, or read the xda threads to learnd about the phones. All your apps have very bad wakeup issues. This apps run all the time and dont leave the phone to sleep. You use malware bytes into android.... the linux is not windows 10. You dont need this crap apps.

Should they always be sleeping?
