Battery Drain on galaxy s8 - Samsung Galaxy S8 Questions and Answers

I have now had my galaxy s8 for over a year and i have noticed my battery life hasnt always been that great.
I have noticed that over a total day i only get 2-3 hours screen on time.
For an example when i go with the bus home for 25 min my battery often drains over 10% without even using the screen for 25 minutes.
Once i installed another rom called lightrom or something over the renovate ice rom and it got much better the first day but second day when i got more apps on it begun to be bad again.
I then went back to renovate ice rom and i was back to bad battery life again when i installed all my apps.
BUT in this case i have an app called greenify and i greenify all my apps in the background but i still have a massive standby drain
I have never found out what has caused my problem but for sure it cant last a whole day
I have this thought that it can be weak signal but i have disabled the option "Keep mobile data turned on" and followed multiple tutorials of how to make battery life better
AOD off, Location off, Wifi off, bluetooth on ( for gear s3), nfc off,
So i only use bluetooth and mobile data.
I apreciate all help

Since the problem starts when you install your apps, I would start with checking which apps are the culprit. Apps like snapchat and Facebook are notoriously known for unreasonable high battery drain in standby.

Personally I have auto sync off, no battery saver, amplify, and display set to WQHD but I also use dark themes via substratum and my average battery life is roughly about 8 hours SOT

I have deleted Facebook a couple of weeks ago and that made no huge difference. Though I think snapchat may be the one. But I often have it hibernated

Normal battery drain over night?

Hi guys,
I have SM-N900 Note 3 and was worried about the battery life.
I factory reset it and only signed in with my Gmail account.
I left it for 7 hours at night, and the battery has drained from 100% to 93%.
Is it normal? I always thought Note has much better battery life and without nothing running in the background it should drain like 1%-2% over night.
what do you think?
(running stock Samsung firmware, 4.4.2. no SD card)
Thanks
If all working well my Note 3 would drain about 2 % overnight, (thats on wifi with BT, GPS on, no power save, no blocking of any type), anything above 5% I usually start looking for the cause. But to be honest with original 4.3 I rarely had to look, since I updated to 4.42 it's all over the place from as high as 20% to as low as 2 % and I can't pinpoint the cause, which drives me insane. ATM it's running about 4-5%, which I'm not too happy about and if it get's any worse I will start deleting everything until I get this phone under control. I have couple chinese tablets, where inside the settings there is a menu where you can stop programs from start at the boot up time, I search everywhere and I can't find anything like that on the Note, but since I'm rooted I can freeze or delete stuff, maybe not the best solution but it works.

woah, so many crossed data about your %.
and yeah - since you're rooted, you can install Xposed and install BootManager module, so you can see which apps are running from the boot.

greenfiy is the best software for us
http://forum.xda-developers.com/showthread.php?t=2155737
2% overnight - 7 hours - for me. Data on, no sync at all, weather widget update every 30 minutes, KK, Faux kernel.
0% - If I turn on Powersave when Screen Off in Performance Profile(Xposed Module). It is amazing with of course a slight delay when turning it on. [Around 8hrs]
1-2% - Depending if my network is stable. Wifi-on. Zooper Widget not greenified. [Around 8hrs]

Need advice about battery drain

Hey everyone, I purchased the 6P a week ago and I really don't understand the battery in this thing.... I'm coming from LG G3 which never faced battery drain during stand by. I am not even using the 6P (still haven't migrated from the G3) because of the unreasonable battery drain during sleep, I have WiFi always on and (no I don't accept to turn it to Never during sleep) I never did this with any phone anyway, my G3 doesn't lose more than 1-2% during the whole night (7 hours).
Please take a look and tell me if this makes any sense because I'm thinking of returning the thing if it's not just a software issue:

Battery life is really hit or miss, many lose 0-3% during the night while others like yourself lose a ton. Try changing your WiFi to either 2.4GHz only or 5GHz only, as some found that helps out. Custom kernels can also control WiFi wakelocks, and I've found running Franco kernel does a great job at helping standby life.
How's the signal strength from within your home? Having a weak cell signal can assist in battery drain. However that's some serious drainage. I'm thinking you have one or more wakelocks preventing the phone to deep sleep. If you're rooted, greenify is a must. It has boosted my battery life by a ton. I would also try to get some more battery stats applications. Better battery stats was/is my favorite app but I'm not sure its working on MM

Although it is not convenient to switch between the 2 bands ( Work is on 2.4GHz and Home is on 5GHz) but I will try it to see if it helps any.
Do you think this will be fixed with software update? and is it because Android M or because 6P on Android M?

Signal strength is fine at my home ( never faced an issue with G3).
I haven't installed anything that can hog battery like that, I only set-up Email, Hangouts to Sync, I never used Greenify or any battery saving apps ( The battery should last as advertised with it's standard capacity), i'm not asking for a magical battery life, just what's expected of a 3450 mAh.
I'll post Sambatterystats results shortly.
See if WiFi scanning is turned off
Many say the battery drain issue really spiked with the update to Android 6.01. So it appears to be SW related, and not HW, FWIW.
I found my fix is as Geoff53 said above, install a custom kernel (Kylo in my case). And I use Greenify on top of it. Great battery life now.

I hope it's just the 6.0.1 .. because I really would hate to return it..
Well, I'd go as far as flashing a custom ROM if that would completely solve the problem, not just the Kernel.
I initially had bad batter drain, not now. Unplug 6:30 am and 10pm still have 45%. Use to be dead by 7pm. I found the culprits were bad apps that I thought were OK. Ebay, Amazon, Facebook, ESPN, Waze.... when I deleted these and a few more, then rebooted all was good. Haven't tried putting them back though. I leave GPS, WIFI, blue tooth... all on. Even have 3 mail apps all set to "push." I don't twitter though.
Make a back up with Titanium or MyBackup, factory wipe and reset and see if your battery improves with only basic apps and mail. Bet it's bad apps. If improves slowly add apps until you find the culprit.

In my opinion, the " Bad App" theory is getting a bit out of hand. I installed the same apps as on my G3 (never had a bad app on it) , and 6P has been factory reset and insatlled nothing at all, only logged into gmail and hangouts, and I tried with the (WiFi during sleep set to never ) then the drain is not as bad anymore but I lost realtime push notifications which is unacceptable.
Now if believe there are so many "bad apps" then we can have the Doze which is supposed to minimize app drain if not terminate it, but that's not the case here obviously, so I think it's actually specific WiFi bug on Android M and not bad apps.

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.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.
Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?
Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.
i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off
Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.
My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?
how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )
Any update. İ have the same problem

So what did you do?
Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).
I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!
I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.

my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Trying to track down cause of recent battery drain issue.

Hello all,
So I know there's various discussions all over the web about the Galaxy s10 and battery issues on both Snapdragon and Exynos variants. It seems people are experiencing a wide margin of difference in avg battery life..
So here's my situation. My wife and I both have S10+'s through AT&T. We got them the first week they came out. I looked though the forums and performed several battery optimization tweaks on both phones and since then the battery life has been really impressive... No complaints really. Until this last week.
We both recieved the March security patch and fingerprint scanner fix about a week ago. My wife's phone seems unchanged by this. Everything working as expected. My phone however has been draining battery MUCH faster both in SOT and standby time. I'm losing 2-3x more battery % overnight. In the last 20 mins of just reading through threads on the XDA forum app, I've lost about 10% battery. I'm sitting in the dark with my screen brightness very low too. (down another 5% since I started typing this!)
My wife and I have very similar phone habits. Since both our phones are optimized identically, and we used most of the same apps a play the same games, I started looking through everything different I've done in my phone since this problem started. I installed Adhell3, which seems to be setup properly and working. Mike B. from Adhell's Discord assured me that Adhell shouldn't be draining my battery. I'm mostly using it just to remove a bunch of basic bloatware and block some ads.
The update seems to have worked fine otherwise. My FP scanner is much better now, but something is definitely wrong. I've tried wiping the partition cache afterwards. I've tracked down others experiencing issues after this particular update, but cant seem to find a way to fix this problem yet. I saw something about Deep Sleep problems after the update when someone uses a VOIP service like Skype or WhatsApp, but I dont use anything like that. I can't even find a good tool to use to see more information about my battery usage, as the built-in battery monitor lacks a good deal of information. CPUspy doesn't work on my version.
If anyone has any ideas of what could be the culprit, what else I could try, or what tools I could use to try and track down what exactly is causing this sudden increase in drain, I'd really appreciate it.
Which update do you have ASBA or ASCA? This is rather weird, Battery drain can also come from restoring from backups. I lose 2% every night and my phone is on airplane mode, not connected to anything except location. I do not have adhell, and last time I tested before the fingerprint update I had 10h SoT on wifi purely. When I got the new fingerprint update I checked if the phone went to deep sleep and it does, so I really do not know what might be your issue. I have an exynos variant btw. Also I charge my phone constantly from 80 I let it drop to 40 and charge it back, I do not use fast charging options. Since unplugging my phone now on LTE fully I have lost 1% in 30 min, I have my fitbit always connected, location on, max resolution, I have a semi black wallpaper and brightness around 40-50%.
I will see today how much SoT I can get from 80% part wifi, part LTE, I will update.
clear cache helped a lot of people
Update 1
Reset all phone settings to factory. Don't do full factory reset, just all the settings, fixed my post update battery drain issues

Update 2
Hrrm. It seems I don't have ASBA or ASCA, I have ASD3. The March update.
I'm really hoping I don't end up having to factory reset and manually install everything... Because I did do a restore from backup with AT&T Transfer, because it seemed really convenient and time saving. I had no idea that so many people have had issues with restoring from various back up services (AT&T, Samsung, Google etc.)
I did the same restore from backup on my wife's S10+ too and she's had no problems. Her battery life is phenomenal. My battery issues only started after this last update.

Well that seems rather strange to be honest, you can eliminate possibilities by just testing and see what works. Last possibility can be that factory resetting and installing all new, but then again, it could be that it solves your issues or not. You should be having rather horizontal lines to prove your phone is truly going into deep sleep in my opinion, but also you can check with CPU Spy
Sorry it will be this pic
Try to log too safe mode and check the battery drain
If stopped then it was from an application that have a problem
If not I think it might be a system app or something
So. I'm starting to think that some of my problem has to do with wakelocks. Unfortunately I have limited access to wakelocks statistics since my phone is unrooted. However. Last night I fully charged my phone right before bed and then took it off the charger to see how much it would lose overnight. It dropped a whopping 10% vs the 1-2% it used to.
I looked through some of the battery info and noticed several apps running in the background for very long periods of time since last night. Chrome(2hrs) , Discord(2hrs), Google Play Services(a whopping 13hrs 30mins running in background) and Google Play store (5hrs)
Somehow Discord was responsible for draining 7.6% battery in that time!
So, could this be a wakelock issue causing my phone to lose so much battery overnight? I know that's only half the problem, because I'm also experiencing higher drain than usual while using certain apps too. But I'm trying to figure out one thing at time.

You can look at this thread and see if you can install the app without being root or not

You just need to tweak your settings more, put which apps do not run on the background or go to sleep, how many days you need to wait to put unused apps to sleep. Is all tweaking the settings.

Then I don't what you can do, either do a factory reset and so not restore anything from backups and see if that works. I usually set my phone that way, clean no restoration from any backup all apps are installed manually, and I do not even use adhell to disable most of Samsung crap apps and services.
