[DN4] My Personal Battery Optimization for Note II - Galaxy Note II General

For those using Ditto Note 4 awesome ROM, you might be aware of several reports of noticeable battery drain issues..
http://forum.xda-developers.com/showthread.php?t=2504016
The thread is full of discussion on how to optimize battery consumption (including me) and until our awesome devs confirmed whether it's a ROM or user issue, (it's not present on other ROM users) we should find our ways to find a solution
Below is my personal battery optimization, it worked for me and not sure it will work for everyone. I'm just here to share what I did and how I succeeded.
I. IDENTIFY YOUR DEVICE USAGE (expect a heavy drain if you're a heavy user).
First of all, I'm a mobile person. My lifestyle, either personal or at work greatly relies on always being online and connected.
So definitely the battery of my devices hates me, and I hate them back if they disappoint me haha
My Note 2 setup is as follows:
- Running Dn4 ROM, plus Updates 1-4
- Agni untouched (not Overclocked, not undervoldted)
- I got a Samsung Gear 2 smartwatch which is always connected via bluetooth. It also requires a standalone application on the device - Gear Manager, which installs prerequisite sub-apks for continuous communication between device and the smartwatch.
- Wifi and mobile data always on for reliable online connection (the city has a blanket wifi + I got unlimited data plan)
- Usage: moderate to heavy
- Frequently open applications: Web browser, Gmail, Viber, Skype, Clash of Clans, 9Gag, Perfect Viewer (Comic reader).
II. IDENTIFY WAKELOCKS (to see which triggers and keeps your screen and CPU awake)
1. Install Wakelock detector.
https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector
2. I recommend to do this before you sleep. Keep your phone fully charged. I suggest to reboot your device then open your frequently open applications (just to freshly start their processes).
3. Don't use your device (that's why I recommend to do this before you sleep). You may start dreaming about unicorns then. JK.
4. Expecting you wake up several hours after, you may check your Wakelcok detector results and see which apps or proccesses are keeping your device awake and how frequent it was triggered.
Note: the app shows two types of wakelocks: Screen wakelocks and CPU wakelocks. You better check them both.
II. APPREHEND YOUR BATTERY HOGGERS (based from Wakelock Detector results)
1.Uninstall those apps you think you won't need or unnecessary.
2.If they are system apps, or you think you might need them in the future, use Titanium Backup to backup them before uninstalling.
https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup
3. Greenify those apps that you prefer to get hibernated when you're not using the device.
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
For my case, I've found out that S-Health, Geo News, Facebook and Viber were the top battery hoggers.
- Saved a backup of S-health and Geo News on Titanium Backup, then uninstalled them both.
- Greenified Facebook, XDA app and 9gag as I'm always online on Desktop during my work (FB, web browsing, and playing mobile games are allowed/required on my work, how awesome is that! lol)
IV. CALIBRATE YOUR BATTERY
Note: We all know our battery deteriorates over time. This might result fake/virtual battery level of charge shown on the status bar. This battery recalibration feature helps to fix the incorrect percentage of charging level.
1. Charge your device up to 100%.
2. Once fully charged, disconnect your device and enter this code to the phone dialer: *#0228#
3. It will show your battery status, at the bottom, select "Quick Start".
4. The device will somehow "refresh" and you'll notice a battery drop from your device.
5. Plug again your device and repeat steps 1 to 4 until you don't get a battery drop (device remain 100% when your device "refresh")
Before, I need to recharge my device 2-3 times a day.
Now I'm able to use my device for a day (maybe longer if I lessen my online activities).
Hope this helps and let you maximize your battery usage.
Galaxy Note 2 with Ditto Note 4 ROM rocks!

Great share.
Just a note; You're lucky of the fact that a device running on wifi alone eats up less battery and you being able to use wifi frequently is indeed fortunate.

Indeed. I'm currently living in a wifi-friendly city.
Additional note for this optimization: I quess the smartwatch helped somehow by doing its duties: to have a quick access to my notifications.
That way I don't need to wake my device just to see the time or check the notifications.
I can even do phone calls, text messaging and monitor my calendar just using the smartwatch so maybe that helped as well.

Hi!
Great stuff! I was looking for an app like wakelock detector for a long time...
I have a little problem with the calibration... I repeated the steps yesterday for about 10 hours (20-25 times) , but I didn't get any closer to staying on 100% after pressing quick restart. Sometimes the battery level goes to 83%, 87%, sometimes it stays at 95%-93%. It seems totally random. Maybe it is because my battery is old, and can't be charged till the design levels ?
How many times did you repeat the process ?

After the device is fully charged, it only takes me 3-4 times to repeat the process. Can you try letting the device plugged-in for at least 5 minutes once it reached 100% before proceeding to step 2? Yes, there might be a possibility regarding the condition of your battery but mine is old too but the calibration went smoothly.

Attention!!!!!! Everyone with battery life issues please read this!

I think I finally found the solution to lousy battery performance on Android phones in general!
If you are using Spare Parts -or any other battery monitor app- and noticed a near 100% of awake time then,
it's as simple as that:
Go to menu, choose Settings->Applications->Development
and make sure that Stay Awake (second option) is NOT checked.
If it is checked the phone never sleeps while charging, but unfortunately, due to an android bug I guess, won't return to his regular sleep schedule after disconnecting from the charger.
Please try this and let me know! It worked for me!

Do you have Spare Parts installed?
If yes, then you can see what exactly is using your battery.
My solution applies to those who constantly have near 100% awake time.
I hope you find your culprit soon!
Timescape is the culprit.
Force close it and remove it from your home screen and watch your battery life double.
Well i'm having the 100%, so i will defenitely give it a shot. Thank you.

You speak my words absolutely right Timescape is the Main Battery sucker and nothing else. I removed it Days ago including of closing the Process in Taskmanager. my battery Life got up from 7 Hours to 16 Hours. Nothing else had effect for me even changing the Launcher to Helix or whatever.
Timescape / Mediascape is what sucks the X10 down.
No timescape on my homescreen and stay awake is not checked...still batterylife is lousy
Its fine when its not being used but as soon as i start using apps or use the phone in general, the battery drains fast.....
I reset the phone after unplugging it in the morning after a full charge, and my battery lasts a good 18 hours. Thats with Wifi on 75% of the time and 3g always on.

Wow....thats great...how did you manage that?
could you guide me through what settings you use please
cause with wifi on ....i get like half a day!
3 to 4 days with wi-fi off,3g off and gps on......................
don't twit or face though.
After being fed up with barely making it throughout the day, I decided to perform the following experiment:
1) wiped the phone clean (factory reset);
2) did NOT configure my google account with the phone to avoid needless sync with google as well as all those processes running in background no matter data connection available or not;
3) disabled data (as that line I am testing the X10 on has no data plan on it);
4) switched off location services; removed every single widget from the home screens;
5) installed HelixLauncherDONUT and left default widgets + added SE's digital clock;
6) installed startup auditor to prevent stuff like timescape from starting
7) contacts/settings/show status updates changed from all to none
Now after 24 hours and 45 minutes since unplugged phone has 88% battery left!!! There was no usage beside me checking stats every few hours. Phone is set to 3G, so switching to 2G may yield even better results.
Before this test I have done exactly the same test with the only difference of Google account being enabled on the phone (with sync disabled). No matter there was no data connection at all, phone went thru 20% of battery in just 6 hours with same usage pattern - 'no usage, just standby and checking every now and then the status of battery'. Not bad as with normal use of the phone I was been able to make it thru the day without shutting down due to battery empty.
Bottomline, I blame Google services for the excessive battery drainage in this phone. It is 1.6 'Donut' with its outdated google services 'at fault' IMO.
Hopefully with the planned Eclair update (lets hope Froyo too!) this situation will be addressed, at least to a certain degree.
Cheers!

Don't get me wrong. The experiment I've done is a "proof of concept" sort of - I am trying to figure out what is wrong with the battery usage in this phone.
If we look from your point of view, just to have the phone on standby and not using it, not Motorola V3, but a toy phone from the dollar store would suffice.

oh, i know. i just upset with SE, we're here to find some solutions
it's so sad that we buy the phone for the look & the features, too bad that SE did a very bad job. now we have to wait for months to get an update from them, & still don't know it'll fix all the issues???
What I've found out is that most battery drain comes from apps. Install an app that monitors cpu time per app and cpu speed and load. Shortly after I got the phone I was about ready to throw it from a bridge or something because of the horrible battery performance. However, one day I noticed that the cpu was running at ~1GHz most of the time even though it's supposed to throttle down and match speed to need. I found out that one app had ALOT more cpu time that all other apps/services (a widget from DMI, the Danish weather service, in case you care). Once uninstalled, my phone could go through half a day with both 3G and Wifi enable and not even drop below 90% battery capacity - although only mild usage because I was working. Before, the battery went from 100% to like 60% during a night with 6-7hrs of sleep.
Finding out how to improve battery usage has definitely made me like the phone alot more, but I still wish HTC had made the software for it.
Regards - Martin
I get a good full day with my x10. I use Timescape but set the update option to NEVER so it only updates by tapping on timescape tile; i also turn of wi-fi when not in range of my home wi-fi, bt off, gps off (unless needed for maps).
I also trained the battery. Let power off by itself and charging full 4 or 5 times.
as for the google thing id suggest going into settings then data synchronization.. click google and uncheck background data.. it even tells you it will save battery and lower data usage.. whenever you use market though it will ask you to enable it in order to use it.
hope it helps!!

To follow up on my test - 7 days, 18 hours with 3% battery left. Here is a quick video I made: http://www.youtube.com/watch?v=lt2YjrREgxg
for me i use Launcher Donut
and disable data and mms
settings > wireless controls > Mobile network settings > MMS & DATA
try it and tell me how much u will reach in the same daily using average
Removing Timescape & Mediascape totally from the home screens.
and disabling Data Sync>Gmail
battery life is showing huge improvement.

I solved my battery drain problem

I was having a problem with fast battery drain on my SGS2. I would get 15 hours if lucky from a full charge with light - moderate use. My most recent charge looks like it has doubled the time.
What did I change? I did a factory reset and manually installed all my apps, NOT using titanium backup. I had used titanium backup to restore apps only, that were from my previous phone (Nexus1). I have never used titanium backup for system settings, only apps, but it seems even that is unreliable. I've now stopped using titanium backup completely.

Can anyone verify this...
Will it matter if it's i9100 to i9100, or just any other phone to i9100?
Well... Ive done several hard resets , because I though I had a network problem , and I many of those I didnt install titanium or even root the device and the battery life was the same.
Just one opinion..

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.
Regards.
I am sure battery drain has to do with the apps we installed and the settings we use.
We are in a fortunate situation that my wife and I have both S II, hers is 2 days older from the same shop, so I assume both devices are from the same batch. Hence no hardware difference.
I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.
thx for info man.
What would happen if i turn that off? I want to try this to preserve my batt life. Thanks!

PB_2003. You had to use one phone to make a shot of another phone? Just hold down the home key and press the power key. You will be able to take shots like the attached.
I have used TV to restore many times and battery life is fine. I'm would suggest that the issue is some app you are restoring rather than TB

I wonder if having 3rd party launchers like launcher pro drains the battery quicker. I installed launcher pro without ever having really tested the battery life of the phone with the standard launcher. Has anyone here tested the difference, if any, of the battery life of standard v market app launchers?

The screen shot on the left is your phone correct? It looks like something is waking your phone up and leaving it in an awake state for far too long. Your graph represents over a day's time and I see those huge chunks of time where your screen is off but your phone is awake; I'd say some program is what do they call it *wakelock* every now and then.

it's not just the apps that was just installed. It should include apps that are updated. I had this issue on SGS I when beautiful widget was having issues with updates causing the phone to use more battery power than usual
Morel likely to be a bad app, or a bad app setting causing the app not to close properly then drain power than the mere fact you restored it via titanium.
anyone one trying while sleeping, off your packet data ?
for me i tested,
2350 @100% to 0700 @ 99% (during packet data off)
If on, it will left 70% ++ in the next morning..
why is that so?
This is my battery drain using Litening ROM 1.5
I usually make and receive 30min phone call a day, push email on 2 accounts, wi-fi at work, data always on.

Turning off data packet doesn't allow any application going on line (unless you have your wifi on) and cannot download e-mails, synchronize anything, etc..
This saves your battery a lot.

Yes, that is also what I suspect. It is just to find out what which application / settings this cause.
I found out that I have 4 apps has an "sync" account, I delete all of them (except gmail), now I got a lot better performance (1 day: still 75%).
I'll post later my picture

Of course the updates are included. There should be an app/good optimized app which will allow us to close the apps and thus Auto Sync and Background Data to off when we are not using them, especially at bed time. The in built task manager's RAM Clearance function is crap and frankly I haven't found an app which will optimize the RAM without force losing the apps/widgets. Tried 'Gemini App' but I doubt! This 'Sync' stuff is the main responsible part of high battery drain.

NEED HELP: New To Note/Android.

Before getting the Note, I've been an iphone user ever since the first one came out. I switched especially because of the nice large screen which is handy for the type of work I do.
Some questions though:
1- Battery Life: I was pretty handy on the Iphone in getting everything I didn't need (some notifications, location services on certain apps) turned off to safe battery...while keeping only the ones I wanted. I haven't figured out how exactly to do this on the Note. My battery life is poor...at least compared to what I was getting on the iphone. I typically start my day at 8:30AM, and yesterday by 6PM the battery was already at around 10% (where I can't take pictures....)
2- Must I have GMAIL app and MAIL app? For some reason the GMAIL app's emails update much quicker than the main app I use MAIL. So when a new mail notification comes in I have to manually refresh the MAIL app for it to catch up with the GMAIL app. Otherwise I would have to wait a couple of minutes of the mail to show on MAIL app.
3- On Mail App I have two email accounts. Why is it that my welcome page is the page showing my accounts rather than my "ALL MAIL" page which is where I left it originally?
Thanks for sorry for the NOOB questions.
Ad 2):
Depending on what other email account you have there colud be an specific app for that provider that also supports push email (eg. Yahoo). Or you colud configure Google Mail to poll for mails from your other accounts.
1.) try to close auto sync, bluetooth, gps and use wifi everytime its available because 3G drain much more battery. and lower the brightness on ur screen to ur lowest, that can save a lot of battery (just open them when u need to use it)
or Root your Note and use custom rom. There are many roms that help you with battery.
hope that helps.

Battery - 10% in a day??! How much were you using the phone?
Allow the phone to fully charge and discharge for a full cycles. The screen is a big consumer of power - don;t use auto-brightness and keep the screen down to the best workable level for you. Also, the more apps you have using push syncing, the worse your battery will be.
Depending on what you're using the phone for, you should easily get a full day's reasonable use out of it.
I agree with the point shaoran_ojo made about wifi - but also turn wifi off when you're not using it.
Finally, it's absolutely right that many of the custom ROMs will give you better battery life
You can check the battery usage over time, if you go to Settings menu and then About phone -> Battery usage. You will see there what eats most power (most likely, Display).
Touch the chart in the upper part of this page to expand it - see if you can relate biggest drops of battery charge to some particular activities. For example, playing Crayon Physics drains the battery extremely fast.
Do you happen to be in areas with poor cell coverage? I've had phones drain like there's no tommorow in poor coverage areas, especially when GPS is turned on since most phones are equiped with assisted GPS chips that use cell-tower triangulation in order to get a faster fix on your position.
You could root your phone and switch to custom kernels or roms for better battery life as well as performance. A few ways in which you could then save battery are by undervolting or underclocking the processor or using an app like titanium backup pro to freeze battery draining apps. Wifi is also a big battery drainer. You can set the wifi sleep policy to screen off to curb its usage or keep it off entirely when you dony need it. Gps and bluetooth can be kept off and the screen brightness can be lowered. Im sure you wont be disappointed with the note's battery life after you tweak it right.

1- Battery Life: I was pretty handy on the Iphone in getting everything I didn't need (some notifications, location services on certain apps) turned off to safe battery...while keeping only the ones I wanted. I haven't figured out how exactly to do this on the Note. My battery life is poor...at least compared to what I was getting on the iphone. I typically start my day at 8:30AM, and yesterday by 6PM the battery was already at around 10% (where I can't take pictures....)

First of all decrease the screen brightness if possible. I have my brightness set to minimum and I have Screen Filter (free in the market) installed and set to 50%. This setup works for me when I am indoors and when I am outside I just disable Screen Filter. Hopefully it will work for you too, maybe with a little tweaking of the exact percentage.
Then take notice if your phone is unusually hot when you haven't used it in the last 5 minutes. This may indicate there is an app keeping your device from sleeping. Check the battery usage (Settings -> About Phone -> Battery Usage). Tap the graph and look for unusual drops and periods when the screen is not on but the device is awake.
If you notice something, BetterBatteryStats (paid in the market) might help reveal the source of the problem. Cpu Spy (free in the market) will show you how much time has the device spent in each CPU frequency.
If you are comfortable with it just root your device and install a custom kernel. I can't begin to explain how much this can increase the battery life.
Hope this helps and is not too hard to understand despite my bad english.

[Q] Unrooted Note 3 - Battery Drain, Most Tips didn't work.

Hi Guys,
Firstly, I know there are several threads with different tips and suggestions but most of them didn't work for me.
Recently (since more than a week) , I have noticed strange drain in battery and getting hot pretty quickly. It has kitkat and I didn't get time to use it properly in the beginning. After reading different threads and forums here's what I did:
- Let it drain completely, shut off, took out battery for a couple of hrs and then charged without switching on. x2
- Rebooted after charging
- Uninstalled some apps I thought might be problematic
- Factory Reset (such a pain!)
- When attached to Kies, it prompted for Firmware update N9005XXUENC2 followed by another factory reset and hard reset.
- Cleared cache by going into recovery mode.
- Rebooting after charging
But seems like none of it made much difference, my routine use
- couple of hours on wifi
- no heavy games, only temple run, subway surf etc.
- no streaming
- no lengthy calls, not a lot of messaging
- 1, 2 hrs of music
- Syncing off, gps off, blue tooth off, Wifi mostly off, power saving on, brightness on auto, no 3g/4g data, almost no photos and video capturing, sensors, motions off except smart stay
I don't want to root the phone because of my busy schedule, with some difficulty I was able install WLD on it which resets after Rebooting. Point is, I am not a heavy user and this being a "beast" isn't quite unleashing the beasty-battery-life. I do get more than a day but that is when it's in deep sleep for 20hrs or more. I took some screenshots after reseting, updating firmware. It's past 3 battery cycles now, I will attach the latest one's to not clutter it up. I like this phone, but this battery is just not good enough. So, please helpful answers that don't require rooting.
Thank you for reading and Good day!
Is the battery drain consistant or does it happen at certain times (at home, at work, etc.)? If you are in an area where the signal changes frequently that will drain the battery because the radio is using power to maintain a connection. With wifi scanning for google services even when turned off setting make sure it is off if you dont need it. How do you charge the phone? If possible always use the charger that came with the phone, charging from a usb port from a computer is not as strong and can affect the memory of the battery and do not wait till almost dead to charge. It works best to recharge when between 35% and 45%. Look at your background services and see if anything out of the ordinary is running. And it could be possible the battery is defective and you might want to have it tested. I use my Note3 lightly and get 24 to 25 hours over two to three days (turning off at bedtime). This may not help any but this is what I have learned from others with similar situations. Good luck!

Hey MPDnnrd,
Thank you for your response.
It is sort of consistent, did you see the screen is just at 18% and the Android system at 30%? I think this is where the core problem lies - just don't know what and how to fix it.
- Signal Strength: Pretty good, hasn't been a problem
- I normally keep the wifi-scanning off and Now I turned off the location services to see the impact but then I think what's the point of premium device if you have to switch off everything.
- I prefer to use the factory-charger over usb-charging and I read it on several threads to let it completely die and then recharge, guess that didn't help.
- Background services - I don't think so, I kill all the apps as soon as I stop using them, use Greenify to hibernate other, switched off all auto-updates and notifications. Even on Playstore, I switched off the auto-updates and notifications.
- Defective Battery: Now this one, I haven't tested yet not sure how to - the phone's just 2 months old so shouldn't it be good enough?
I know they are not very helpful, but still thank you very much. :good:

I'm sorry to have to say this but I think you got a pretty normal battery drain by looking on your screens. You played almost one hour subway surf(which drains the battery pretty quick) and I guess the other hours where internet (also known to drain battery) or calls/messages. On a not rooted device with stock kernel that seems like normal battery usage to me!!!
However if you like to check these maybe u get a couple of percentages(not that much though I guess):
-Power saving mode in notification drawer makes your cpu clock go down (not sure u got it on not rooted device sry)
-check turn of pen detection in s pen settings
-put the brightness on auto or put it down manually
-if you can change the theme color in apps do so(make it black)
-check the svoice settings so it doesn't listen to your voice
-if you don't care how your phone looks buy a zerolemon battery(I think it makes your phone too big but that's preference)
-don't use a bright background keep it dark colors and no live wallpaper as well
Maybe that helps a little.
I don't see any drain either. Almost 6 hours screen on during 24 hours is excellent, additional 1.5 hour awake time for other services. Excellent battery life.
Settings - General - Applications - disable unnecessary apps
In Google Settings, opt-out interest-based ads and disable location access.
Thank you for your reponses guys - thing is it actually had much better battery life. What I don't understand is the fact that Screen % used to be on top and android os and system was below it but now it has been on top.
I have tweaked quite a few things already that 4aces suggested and the S-voice thing seems new, I'll look at it. Today it didn't even last a full day whereas I know people who even after heavy usage get easily more than a day - mine one, I don't use it this much. The Zerolemon thing is beast but then the phone is a freakin block lol so heavy and big, good travel etc. where you can't charge your phone and has a rugged case.
But there's a change that I saw today, Android System is now below the screen so I am not sure what made it do that but may the next time I charge it gets better and so on. I'll keep you guys posted after charging it today, I'll monitor what I do.
Blondasisko - I wouldn't really call it excellent, but it's sort of getting better than it was in the first 2 cycles. But how do I reduce additional awake time for other services? Moreover, you might've noticed I got till 1% to get this much time like really stretched it to get there.
Someguyfromhell - Already done, locations were off starting today.
Can anyone else comment on their daily routine of usage and the battery drainage ratio?
If I get 12 hours and 4hrs screen time I'm happy. I don't even play any games. Have a lot of accounts syncing lot of Internet and a bit on the calls, gps. I get on average 14 -16 hours
I have brightness on high. If you put it on auto it makes a big difference.

I guess I should feel lucky, I have ZERO syncing, auto brightness, no live wallpapers or gimmicky stuff on, no gps, hardly 10mins or so on phone calls and prolly 30-60mins on messaging a day.
@all others - and the Android System is back on top - what could be the possible reasons for it?
I think its because of such minimal use that the system goes on top. The system still had to operate so when you have hardly used the phone then the system will go on top. Though with that usage you've stated you should get nearer 2 days really

You're right probably, this is what I'd like to know as to what is running in the background that drains more battery? Exactly, at-least 1.5 days is what I should get with this usage. May be I should buy a new battery and see how it works.

Massive wake lock and battery drain

Hi guys,
I have been having an issue with my Motorola X Play (UK Single Sim) I have only owned it for a few months from new.... The battery is draining fast and I can see in the battery stats that it's not sleeping, otherwise the battery usage page shows nothing of interest, apart from perhaps Mobile Standby which is quite high, above the screen but the signal bar is all green...
I rooted my phone to better find out what was causing these issues, otherwise stock Marshmallow. Unfortunately Motorola now are not interested as they say my phone is rooted and now has no warranty - useless idiots!
Using GS Sam battery monitor (rooted) I can see that the following is keeping the phone awake, no other app is.
48.3% of battery consumed by Kernel (Android OS)
Keep awake over 2 hours
CPU usage 59m 53s
Number of Wake Locks: 1
Byes sent: 246.21KB
Bytes Received: 5.70MB
App UID: 0
Wakelock Detail:
Google_C2DM 0.0s (1)
I have tried safe mode but it appears to be the same, I have hardly any apps installed apart from Facebook and Facebook messenger and I have even tried it without them...
I have tried turning off/on WiFi / Location / GPS is now disabled. WiFi Scanning is off. Restarts make no difference... I have even done a factory reset about a month ago.
Any ideas, this phone is having the same battery life or less than my Nexus 5 which had a much smaller battery...
Many thanks
here's a way to avoid it http://forum.xda-developers.com/galaxy-s2/help/google-c2dm-checkin-services-t1321520
i'll update if i find anything else.
don't tell them your device is rooted. if you go to service center just re-lock the bootloader and its back to normal.[it won't get your warranty back but they don't check that much]
can you post a screenshot of gs sam.
1 - Install BetterBatteryStats (BBS) - this will give you detailed information on what is draining your battery. Get it from XDA v2.2.0.0B6 - this gives you the detailed breakdown in the UI that you are after, the google play version doesn't do it in the UI (older version).
Get baseline results (charge it full, don't touch it for 5-6 hours) I like to do this while sleeping.
2 - Install Greenify (you don't need the Xposed module if you don't want to fiddle with that yet, alto I highly recommend it) set the working mode to root. If applications are still not sleeping, add the widget and force sleep everything before you turn off your screen
Get BBS results (do the 5-6 hours while sleeping) - improved?
3 - Install Naptime from the google play store (by Fransico Franco)
Get BBS results - improved?
Getting anal about battery usage?
4- Read up on Amplify - this yielded even more results for me. But this can take a bit of work to get right. There's a lot of great threads on XDA for setting this up.
5 -Smart network - allows you to control data, networks, wifi, bluetooh, nfc, gps on/off with a ton of great features for auto. management.
I have all the above and yield a 0.4%/hr drain on stand by (see signature for phone build).
Amplify is a god sent app. It has been 4 hours now, and I have been using whatsapp on and off (about 20 seconds each time) and I still have 97% left in the tank.

Facebook app has been known to cause serious battery drain in the past. Uninstall it and test again.
In 99% of the cases it is caused by an app. Try to find out which one is causing the drain.
Hi all,
Sorry for the delay and thanks for the replies. I performed a factory reset again, after clearing the cache etc, the same as I did last time. The only difference is I then installed Android 6.0.1
The battery drain has now gone. I didn't perform a restore of apps etc, and the only apps I have installed so far in addition have been Facebook and Facebook messenger but I have found these have had no effect at all on the battery drain. I haven't even updated the stock apps (apart from the security ones).
I now get two days of use easy. It also seems to be running slightly faster. I will update apps one by one, over the course of a few days to make sure nothing causes it again...
http://forum.xda-developers.com/android/general/guide-extreme-battery-life-t3095884
I use this guide, works really great to limit wake locks.
And I don't use Fb app but use the browser instead, battery lasts easily two days of "heavy" usage !
I found the problem, or at least a major bug. Whenever you cast to Google Chromecast Audio and then stop casting completely there is a massive wakelock until you next restart the phone. My phone was awake all night and down to 20% battery life. Android OS takes a massive portion of the battery life and under keep awake stats it's 9 hours +. It seems that when it says disconnected it is not. A major bug! I'll try and report it using Google's bug reporter...

not even Doze could kill it? perhaps you could try Servicely and see if it could stop the thing from running.

Nope, Doze had no affect at all but it should be as it was sitting stationary overnight - normally the drain overnight is a few percent at the most, last night it was around 65% and I was left with 20% in the morning and this was I think the first time I had used Google Chromecast Audio since the factory reset with great battery life up to last night... I could try Servicely but I am not sure on the service to kill and I'd like to keep it 100% stock for now so I can help out Google to fix the bug (or Motorola if they bother)... What a pain as I just bought 4x Google Chromecast Audios!!
I have reported it here in the Android bug tracker, feel free to comment / star the issue to bring it to Google's attention.
https://code.google.com/p/android/issues/detail?id=208324
However I am not sure if this is a Motorola Issue or a Google Marshmallow / Chromecast issue?? Motorola support have been very unhelpful so no luck if that is the case...
If anyone else with Chromecast Audio could confirm the bug that would be great.
Thanks
Laurence
There's a post on reddit about battery drain with chromecast audio about a year ago, not sure if it's the same issue though.

maybe this help, on moto g this helped
apart from greenify and naptime...i dont think we have something like amplify yet for nougat devices, also with the governor scripts they are providing better results now
yep
