I'm opening this thread to clean up the Dev thread, since the most probable cause of battery drains are software/configuration related.
Here's my own experience with this matter.
Most of the drains I've seen are related to Location settings and Google Now. It seems Google's Location Reporting and Location History keep pinging WiFi for the location at a fairly high rate, so keeping the phone Awake and/or the WiFi running all the time. An usual indication of this is that in BetterBatteryStats you get:
1) Screen On % very low
2) WiFi On 100% of the time
3) WiFi Running 100% of the time.
4) Awake with moderate-to-high %.
To test it, here's what should be done:
1) Get BetterBatteryStats (BBS), enable Root, install it as system app (in advanced settings). Reboot.
2) Disable WiFi and GPS completely, preferably leaving Data Network also off. You may go all the way and just turn on airplane mode.
3) Leave the phone idle for at least 1h and check that there is no battery drain.
If you get any considerable drain (more than 5%/h), check Kernel Wakelocks and Partial wakelocks, or try again with 2G networks only. You may have a baseband problem. Consider this step as your "control group" as it ensures nothing in the hardware or in the ROM is wrong.
If there is no drain, enable WiFi and GPS again, but make sure all this settings are UNCHECKED:
1) Settings->WiFi-> Advanced: "Network notification", "Keep wifi on during sleep" set to "Never", "Scanning always available".
2) Settings->Location->Google Location Reporting: "Location Reporting" set to off and "Location History" set to off. Or just disable Location completely.
3) Check Settings->Security -> Device Administrators -> Disable at least Android Device Manager. If you can, disable everything else in this screen, such as Airdroid, Cerberus, etc
4) App drawer -> Google Settings -> Search -> Set Google Now to Off. You can also configure Android Device Manager here.
Leave the phone idle again for 1h and check BBS. In theory you shouldn't need to recharge completely, just enable the watchdog in BBS. Always check the wakelocks too.
You should get this on BBS:
1) Screen On % very low
2) WiFi On 100% of the time
3) WiFi Running with low % (anything less than 50% is ok, depending on Sync settings and background apps)
4) Awake with low %.
5) Deep Sleep with almost 100%
Go back enabling stuff as needed, one by one, leave the phone idle and check BBS. Rinse and repeat until you find the culprit.
One thing, make sure you do this after letting the phone sync some of the stuff. Don't do this immediately after a setting up a Google account.
Some people also reported that doing a factory reset solves the drains. It's always recommended anyway.
Any other hints are also appreciated.
For people with trouble making BBS work, Try getting the latest version, enable Root in Settings->Advanced and them System App, also in Settings-> Advanced.
Also:
1) When the phone is charging it WILL BE AWAKE WITH BOTH CORES, ALL THE TIME. Depending on the governor used, both cores may even stay at full speed (aka 1GHz). This is BY DESIGN and stock ROMs does that too. So any measurement while the phone is charging is useless.
2) Most "calibration" procedures are myths and don't have any effect. Erasing batterystats.bin also does nothing to increse battery life or remove drains (but may solve some charging issues, still unclear).
Very interesting.. Good thread and good options to test our battery drain ! thanks for the post.
I'll try this when I get home from school, thanks.
Weird thing happened last night, I thought the battery drain was gone when I recalibrated, but my phone discharged over night, weird thing is my settings show the phone didn't go to sleep once during the entire night, even though it was on airplane mode and I had already used it for like 3 or 4 hours with no apparent brain
There is a lot of battery drain only when WiFi in on. Even if the phone is idle.
I'm on:
Maclaw CM 11.0 [20131210]
I8190XXAMJ2
I'll do the exact tests and post my results.
Do you get notifications with wifi set to never during sleep?

Use the 1st step I wrote above with BBS. Check Kernel Wakelocks and Partial Wakelocks. You will be able to pinpoint exaclty what is keeping your phone awake.
I was about to start a thread on the same topic but my problem is with Carbon Rom 4.4.2 . The phone never goes into deep sleep and is awake 100% of the time. I'm attaching what I see as the culprit in B.B.S. I already disabled sync and yet the wakeclocks are sync related I hope anyone can help me with this.
i just changed to peagusq everything is fine

Notice that the Count is 0 on both GoogleServices related wakelocks. To me this seems that Chrome and something else (maybe G+?) are trying to sync (perhaps the first one?) but are not getting enough network time/bandwidth to do so. I suggest you connect to an wifi, turn on the sync, and leave the phone awake for a while (try not to use the network very much). See if that solves. If not, backup and factory reset are your friends.

I fixed my problem by switching back to dalvik and now my phone only looses about 5% battery overnight.
When I first got the phone, the first few hours of use seems great.
Then, in the past few days, "android os"is showing up as the main drain, over 50% of battery usage AND my phone is dying in about 12 of just standby. Thanks to android 4.4 and lack of safe root method, I cannot determine what is causing the problem.
Anyone got an idea? Location set to battery saving, location reporting and history off, Wi-Fi scanning off, auto sync on with only contacts calendar and Gmail syncing. Removed most apps. Only known good apps are left

Towelroot worked on my D415 to root.
Sounds like the device isn't going in to deep sleep when inactive. I usually charge my D415 over night. The past few days my device has been attached to my PC for long periods of time, thus keeping the battery charged. I went to bed the other night with the battery at 100% and woke to the battery still at 100%. In fact, two nights in a row.
I'd try a factory reset. Re-root if necessary. Then carefully uninstall whatever bloatware you don't want. If in doubt, don't uninstall something, ask first. :silly:

I had the exact same problem, did a factory reset and everything went to normal again.
I can go up to 2 full days of battery even with auto-sync and a huge amount of e-mails e calls ( max time in battery was 72h )
If I leave it on standby it basically drains nothing at all (~1% for each 4-5 hours.
I got 2 D415 (tmo US LG L90).
one have this problem, the other doesnt.
One lasts 72 hrs with 1-2 hrs screen on time. The other is having issue. Factory reset didn't help. Factory reset and no account syncing didn't help. It was fine before. Swapped battery between the two to check. didn't help. Everything seems to work fine for both phones it's just that one is having deep sleep issue. Going to try swap it out with TMO.
is towelroot safe? i dont want to jeopardize warranty. (this is my only use of root at the moment. thanks a lot google.)

Towelroot is safe to use for rooting, but rooting voids your warranty.
does the KDZ flashing (in the LG L90 General forum) remove all traces of root so I can effectively bring it back to stock? Tempted to root to fix this problem (thanks google) but afraid of losing warranty.

Hey everyone!
I got my Note5 near launch day. I love everything about it, except the battery life.
Basically, I am not satisfied. I barely make it through the day with moderate usage. The crux of my problem is idle/standby battery drain.
This has been a problem for me ever since I got my Note5 and even for some of my old phones (M8 on Lollipop).
The Issue: I'm fine with how the battery drains when I'm actively using it. I'm not going to go into much detail about that, but I'm satisfied with how fast I seem to be killing the battery while using it. The part I'm not satisfied with is how much the battery drains when I'm not using the phone. Obviously, this must be an issue with wakelocks. When you look at the screenshot below for Android OS, it is always wake for more than 2.5+ hours in a 15 hour usage period. Now, I'm not sure if that's normal anymore. I don't remember how it was on KK, nor do I know if that's what everyone else is getting.
The Issues Cont: So yeah I have massive idle drain. (I estimated that I get about 1.5-1.6% battery drain per hour. I charged my phone up to 100% and let it sit idle overnight for a span of about 8 hours or so. It went from 100 to 91 during that time). What this means for me is that, I can use my phone less and less because while it sits in my phone, it dies quickly! On GSam, it shows that my battery discharged 38% while the screen was off! Again, I don't know if this is 'normal'. What is everyone else getting?
What I tried: I tried factory resetting. Nope. I tried reflashing the firmware, factory resetting. Nope. I booted into safe mode and left it idle overnight. Still dropped to about 92% or so, IIRC. I actually had the GS6 Edge before the Note5, but I returned it because of the ****ty battery life. Then I inserted my S-pen backward and broke the sensor in the Note5, so I got a replacement. For each instance, I always got crappy battery life. So I am doubting that this is a hardware issue. I tried minimizing the apps installed so minimize wakelocks, but it didn't seem to help.
What I want: Honestly, I just want to be able to use my phone and have it not drain so much while it's in my pocket or on the desk. I want to be able to go into a lecture for a few hours and come out with maybe 1% drain, not 3% or 4%. And I want to do this without rooting. I don't want to trip Knox, and I'm tired of rooting and spending hours tinkering with my phone to get decent battery life.
Attachments: I uploaded screenshots of almost everything I thought would be pertinent. Please have a look and hopefully we can compare results and figure out whether this is normal for a Note5 or not!

I reckom its something you are downloading is doing it. Add one app at a time and see what it does.

Yes there is something keeping your device awake. Rogue app. First guess would be that Facebook messenger app. Look in settings for your running applications, try to limit those to ones you absolutely need using package disabler. If you don't know what's OK to disable, read through the debloating guidelines thread.

Never let Facebook or Games run in the background and MOST IMPORTANTLY disable location services completely. Keep it on a toggle and turn it off until you need it. Always keep it off or Google will ping your location once every minute. It literally halves battery life.

I don't have the Official Facebook app installed.. And I almost always keep location services off, but the battery still drains as it does..
Use the smart manager app to stop certain apps from running in background and restrict background data for apps that don't need it in the mobile data settings.

My battery is amazing and I can say this as I am a battery guru and have spent countless hours trying to squeeze all the juice out of my devices, which includes eliminating wake locks. If you had root you could figure it out, without root you'll have to start un installing apps 1 at a time until it get's better. Also check your exchange accounts.
I assure you something is wrong as my battery life is the best of any phone I've had.

This probably won't be helpful at all as it is a complete shot in the dark, but perhaps you have an app that is trying to get your location continually since you have it off? Maybe try leaving location on. I never turn it off and I've been getting very good battery life on my T-mobile Note 5.

I also tried leaving location on as well. I can't really see an improvement as well. I actually only recently kept location off.

I noticed my Samsung S10 T-Mobile Snapdragon would drain about 15-20% overnight while asleep (6-8 hours) since last week or so. The drain during the day is also significantly worse, but it's easier to compare the numbers when on idle. The first weeks that I had the phone, I was losing less than 5% overnight (6-8 hours). I am not sure if this was caused by the security updates, carrier updates, or a rogue application. I made no changes to the phone settings that I can recall. My phone was connected to WIFI overnight, with cellular, cellular data, and Bluetooth on. Prior to going to bed I would charge the phone to about 80% and unplug it.
I installed AccuBattery after reading some forums and it showed that my battery drain overnight was about 2-3% PER hour. AccuBattery also indicated that my phone was in deep sleep +85% of the time. The breakdown per application does not total the 15-20% so there's something else draining the battery. Eventually, I uninstalled AccuBattery to see if it was contributing to the drain, and it made no difference.
Below are most of the things that I have tried and tested overnight while I slept (6-8 hours), all of them have been UNSUCCESSFUL at solving the battery drain. I might have forgotten some other settings that I have changed. Keep in mind that this took me over a week of playing around with these settings, and checking the battery right before and after I went to sleep.
Restarted phone (There's always someone who would suggest this if not written down)
Cleared Google Services, Google, and other Apps Cache and Data
Cleared Cache Memory (Through recovery menu - Tried this about 5 times at this point)
Reset the big 3 (Reset settings, Reset network settings, Reset accessibility settings)
Enabled Airplane Mode (Cellular, WiFi, Bluetooth Off)
Disabled Location
Disabled Sync
Disabled Always on Display
Disabled ALL Motions and Gestures (e.g. Lift to Wake, Double tap to wake, Smart Stay, etc.)
Disabled Video enhancer
Disabled Game Launcher
Disabled Bixby Routines
Disabled Nearby Device Scanning
Disabled WiFi Scanning and Bluetooth Scanning (Improve Accuracy)
Disabled Show icon when screen is off (under fingerprints - from Samsung Forums)
Disabled certain Apps (AR Emoji, ARCore, Briefing, Chrome, Game Launcher, Google, Facebook, Secure Folder, etc.)
Forced Stop certain Apps (Bixby, Secure WiFi, etc. - they seem to all come back after a couple of minutes anyway)
Enabled/Disabled Adaptive Power Saving (Tried both settings, made no difference)
Enabled/Disabled Auto Optimization (Tried both settings, made no difference)
Switched between Power Modes (Optimized to Medium, made no difference)
Change lock screen and home screen to a 100% black wallpaper
Ran Safe Mode overnight with ALL of the settings above (Airplane with Location and Sync Off, etc.) Still got a 15% drain overnight.
Last night after I got fed up with playing with the countless of options, I decided to Factory Reset the phone thinking that this would solve my battery drain problem. Well, WRONG. Still got a 15% battery drain overnight with only the core apps installed, in airplane mode, location and sync disabled, and other settings disabled. I did NOT restore any backups from Samsung or Google, nor installed any additional apps that did not come with the phone.
I have complained to Samsung through their Samsung Members application under Feedback. If you guys are on the same boat, I suggest we all start complaining so that they can start taking a look at this and hopefully release a fix.
If you guys have any tips or anything has worked for you guys, please let me know.

If its still draining that much even in flight mode, then something is definitely wrong. Seems like you've tried everything. Can you not get a replacement under warranty from where you purchased it? Sounds faulty.
Sent from my [device_name] using XDA-Developers Legacy app
I have had this same issue with my S7. Hence my reply. At that time I have traced it down to a certain kernel process. The only way to resolve this was to replace the motherboard. A factory reset didnt helped either.
Later when i investigated it further it was like an Interrupt request for sleep mode. Eleminating the phone going to deep sleep. Than you will see drains like this
My advice. Get the device replaced. It was the only way to resolve the problem on my S7. Hardware replacement

I installed BetterBatteryStats and got a ~20 drain over 9 hours of standby while sleeping. The phone was untouched for 9 hours, airplane mode on, location off, sync off, and other settings off.
imgur.com/a/1zAj9LP
Also, how did you manage to get your phone replaced? By Samsung? I am past the 30 day return policy so I am not sure how easy/hard it will be for the to replace my device/motherboard. What did you say to them exactly?
Reflash firmware?
Which update are you on?
After the ASCA, but before the finger print sensor update, I had amazing battery life, less than 1% per hour on idle.
But after finger print sensor update, it's about 2% per hour on idle.
Maybe reflash ASCA without the fps update? If it's possible

Spoke to someone in Reddit and he flashed his phone to the Febraury update. It still had bad idle drain.
Additional things I have tried recently overnight with no success
Disabled fingerprint
Removed SIM Card
Cleared memory cache again
I'll wait for the April update and see if that solves things. If not, I guess I'll drop by one of their service centers/genuis bars.
What a terrible experience...
Yeah that does not seem normal.
With airplane mode drop 0.2%/hours.
Sorry you are having bad issues. I would try to install U1 firmware and see if that helps.

I'm having the same issue after the recent updates on AT&T. I used to get close to 9 hours SOT and now I barely get 4. Nothing unusual in the battery stats either so I'm not sure what's going on.
Same here. The idle drain is completely insane! It's a shame that the phone suffers from issues like this when you compare it to the price we paid for it. From what I can tell the issue stems from the kernel not being able to figure out the proper frequencies for the cores in idle which leads to **** performance. I'm gonna try to flash the asd4 firmware via odin once. If it doesn't work I'm gonna get a replacement if possible. Currently I get around 4 hours of sot no matter what I do. Doesn't matter what I do which is super weird. My s7 edge which was at least 2 years old gave me a better sot more regularly, so I'm definitely pretty irritated with this. Will update once I flash over odin.

Same here. The idle drain is completely insane! It's a shame that the phone suffers from issues like this when you compare it to the price we paid for it. From what I can tell the issue stems from the kernel not being able to figure out the proper frequencies for the cores in idle which leads to **** performance. I'm gonna try to flash the asd4 firmware via odin once. If it doesn't work I'm gonna get a replacement if possible. Currently I get around 4 hours of sot no matter what I do. Doesn't matter what I do which is super weird. My s7 edge which was at least 2 years old gave me a better sot more regularly, so I'm definitely pretty irritated with this. Will update once I flash over odin.

To all who has this issues. First thing to check is .. Does the phone ever enters deep sleep ....
I used this app on my S7..
Wakelock Detector. Can be found in google play.. Sorry cant post links due to my new status here.
Znalazłem rozwiązanie szybkiego rozładowania bateri zwłaszcza jak telefon noszony jest w kieszeni. W moim przypadku telefon przez noc zużywa jakiś 3% bateri a po włożeniu do kieszeni w 2 godziny 15% do wczoraj. A teraz Rozwiazanie . Wychodzimy w MENU - ZAAWANSOWANE FUNKCJE - RUCH I GESTY* - i odznaczamy opcję DOTKNIJ DWUKROTNIE ABY WYBUDZIĆ. następnie w MENU - EKRAN BLOKADY - ALWAYS ON DISPLAY - TRYB WYŚWIETLACZA zmieniamy opcję DOTKNIJ ABY POKAZAĆ na którąś z pozostałych lub całkowicie wyłączamy ALWAYS ON DISPLAY . To powinno rozwiązać problem z baterią w moim przypadku kończąc**pracę**z telefonem w kieszeni po 8 godzinach miałem 30% Baterii a teraz 70% .

BetterBatteryStats shows it goes to deep sleep 99% of the time overnight. No abnormal kernel wakelocks/partial wakelocks/alarms.
A couple of other things I have tried recently unsuccessfully while sleeping (6-8 hours) over the past week:
Safe Mode
Safe Mode + airplane mode
Safe Mode + airplane mode + cache wipe + Google services wipe
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaining Apps in Sleep Mode (Battery Settings>Sleeping Apps)
Safe Mode + airplane mode + cache wipe + Google services wipe + Remaning Apps in Sleep Mode + Max Battery Mode (instead of Optimized Mode)
The best idle drain I got overnight was 15% drain over ~6 hours (~2.5%/hour)
I'll try disabling the Adaptive Battery/Auto Optimization while I have all my Apps in Sleep Mode an Safe Mode. I'll also try another Factory Reset this weekend.
If that doesn't work, I'll schedule an appointment with one of their service centers.
This sucks. My 2-year old S7 Edge still has better battery life than this.
I remember reading a post on Reddit from a guy saying he had a current leak on his faulty motherboard. Maybe you got the same issue on yours.

After reading your comment, I decided to test the phone completely off overnight.
To my surprise the battery drain was still present. From 5PM to 730AM my battery went down from 87% to 60%!!! So about ~2%/hour while the S10 was COMPLETELY OFF.
I'll be taking my phone to the service center sometime this week. For anybody else having crazy drain problems, turn your device completely off and see if the drain is still present. It might be a hardware issue

Which update are you on?
After the ASCA, but before the finger print sensor update, I had amazing battery life, less than 1% per hour on idle.
But after finger print sensor update, it's about 2% per hour on idle.
Maybe reflash ASCA without the fps update? If it's possible

Oh, seems like the same with mine, the fingerprint update
Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.
i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.
Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..
battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.
Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery
Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now
i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time
After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help
i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
