[Q] Please Help ! Android System Battery Drain on Nexus 5 after KitKat 4.4.2 update - Nexus 5 Q&A, Help & Troubleshooting

Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.

Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.

Not a lot that can be done without knowing the cause. Consider factory reset?

I am hoping I don have to resort to factory reset and can wait for the 4.4.3 update but I guess my patience is running out.
Thanks for your help.

My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.

having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.

You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

Restart your phone in safe mode, and see the battery drainage...maybe it can help you.

It seems good for me

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5

I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.

Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....

I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.

Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.

Update
Please refer to the OP for update. Thanks all.

battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?

It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

[Q] battery drain in standby, and Google play service problem

so I decided to charge my phone fully then leave it alone for 12 hours to see the standby drain, and This morning when I took a look and I was pretty disappointed. I attached pics, but as you can see, 12 hours of standby and 30 percent of my battery is gone. wtf? another time I did this a week ago with only 8 hours of standby, it drained 20 percent, which if scaled to 12 hours will become 30 percent. Why is the drain so high? Google play services is at the top of the list, and even with normal use it takes about 10 plus percent of my battery. my friends nexus 4, with basically the same apps I have (fb, messenger, Chrome, snapchat, bbm, etc) only had 10 percent after 12 hours. both our phones have the battery saving location enabled, radios on, but the only difference is that he wasn't connected to WiFi and I was. any suggestions? And yes I've looked around on the Internet at other people having the same problem and I still haven't found a fix
Lol sorry I forgot to add the pics in the first post
It's the WiFi. I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
Try disconnecting from WiFi and redoing your test!

oh wow, that might be my problem then. thanks a lot, I'll redo the test and see what happens, thanks
I haven't used WiFi at all today, my phone had been unplugged since 6 am and at 1pm today it's down to 57 percent. I have hardly used my phone today and the play services are killing it.
I think WiFi was my issue actually, I have kept it off all day and after 2.5ish hours I'm down to 72 percent battery, with an hour of screen on and using Google search quite a bit. the screenshot has screen and Google search at the top, Google play services hasn't been up in double digits at all

On your first screenshot Google play services consumed 34% out of 30% of your total battery loss, which is approx. 10% of your full charge. Within 12 hours this would be a 0.85% battery drain per hour because of gp services.
I did the math again for the second screenshot and Googe Play services consumed 0.7% per hour.
Doesn't feel like a big difference for me. If the time was actually less than 2.5 hours the drain could be equal.

Google Now will still function. It just will not show cards based on location. Also when you disable or semi disable location sometimes Search start's keeping you're phone awake trying to find some location information. If this happens just force stop Google search or reboot the phone.

Weather will still work you just need to input you're location into the card settings manually. I used that for a while but it consistently wakes the phone to update it which annoyed me so I use Dashclock as it only updates when I turn the screen on.
Without Locations it will still grab information from the net about your searches, sports teams, stocks etc. It will no longer show you commutes, local picture spots etc.
I've kept Google Now on mainly so I can still set and receive reminders but don't want to tolerate any unnecessary wakes when the screen is off and have accomplished that now.

Not necessary to go that extreme.
I had the same issue as you guys after upgrading. Goto Settings->App->All
Select Google play services. Stop it. And clean data (All, including cache)
Reboot. And voila, it will consume much much less battery (Dont ask me why... Probably some conflict arising on the data file after upgrade)
On a side note, without completely disabling data location, it is worth switching to the battery friendly mode (Location will be evaluated using the network and not the GPS)

I wasn't going to disable it, I was just wondering what would happen if I did
also here are my stats from today, what is android system and android os? why are they draining so much battery? also why is Swype using so much battery?
Researched this a lot, found some solutions, bad and good fixes and after trying some different twists on it after two days this is what I found to be the best, and I decided since this is just as bad as 4.0/4.1 and the mediaserver battery drain I might as well try and help at least 1 person by mass posting this reply I wrote else where to other threads, so here you go:
"Hey- I don't know if you, or anyone else has found a working solution, but here is the way I found best:
Note- I am on galaxy s4 [sgh-i337] running a 4.4 KitKat rom. I have found the following work around to work best for me:
1 Google now & Hotword detection=OFF,
2 GPS = OFF and turned on only when needed, eg maps/checkin on facebook/whatever needs location.
3 Settings-> Manage Apps -> Google Play Services -> Manage Space -> Clear All Data.
**Optional:After this [root only] I go into KT tweaker and make sure my phone cpu is set to a max of 810 Mhz when screen off.**
This fix usually works until I reset the phone. I ALWAYS follow those 3 steps when rebooting. AND always check that after I've used GPS that Google Play Services isn't keeping my phone awake. [Eg, after 30 minutes I check if the phone ever went to sleep again when the screen was off.] IF it does act up, I repeat steps 1, 2 &3. I still get notifications and all, and this is the least feature disabling way I've found that works with the cost of a little micro-management of your phone.
With this fix I can idle for an estimated 5-6days. As I take off my phone from charge at 8am and at noon with minimal usage [maybe 4 or 5 texts] I am at 97%. With WiFi on & connected.
OTHER: I personally keep NFC&Android beam&Bluetooth OFF, and turn ON when I need it on. Other- WiFi is always ON, and "Scanning Always Available" EDIT: Now is OFF, "WiFi Optimization" is checked ON for me. And for location mode when I do have it on, I keep it at EDIT: Device only. Using only gps to find my location.
All in all, I hope this gets fixed."
I can post screen shots and all if somebody wants them or if there is need for one

thanks! but wow i wish my battery would be that good. i actually did so,ething else, i turned off the location reporting like someone earlier said and google play services dont even show up anymore. using device only disables location reporting as well so they both should have similar improvements.

Nexus 5 battery life

Hi, I really did some research but I find alot of ROMs and Kernels and I always get lost. I just need a good safe way to better the battery life of my Nexus 5 and keep it's stability and all the functions it has. So I wanted to ask what you guys recommend as Kernels, apps and lastly (I dont want to change unless its worth it) ROMs.
Sorry, its been hard without a PC to do decent research.
Enviado do meu Nexus 5 através de Tapatalk
The ROM has very little to do with battery life. It's all about the kernel or the apps.
We can't recommend kernels (or roms) as this is against the rules. They will all pretty much help with battery life. Just try them all- yourself.
Apps:
Greenify
Better battery Stats
That's it. Anything else I would recommend is going through all your settings and turning off things you dont need like location reporting etc
if battery life is all you are looking for... the difference are ... not much
Just disable google apps that you do not use, then you are good to go.
Locations settings, always off, activate only when needed. uncheck all under Google Location Reporting.
Disable NFC if not needed.
If you don't have good LTE coverage, change it to 3G under mobile networks.
For maximum battery life, do NOT activate Google Now.
eg. (These are apps I've disabled)
Drive
Earth
Email
Exchange Services
Face Unlock
Gallery (I use QuickPic as alternative)
Gmail
Google Hindi input (These ones gets disabled once you uncheck them from input settings)
Google Play books
Google Play Games
Google Play Magazines
Google Play Movies & TV
Google Play Music (I use Poweramp *Paid)
Google+
Keep
Maps
News & weather
Quickoffice
Street View
Tags
TalkBack
Hangouts (I use HoverChat *Paid)

What he said ^^^^
It doesn't matter what's on your phone....you should be able to get good battery life. Its all about setup and usage.
Just gotta troubleshoot issues occasionally.
Please check the thread linked above, and read read read. . (Start on last page and read back for a bit....a lot of good info)
On my phone it certainly seems to have something to do with signal quality. At home, I can put the phone next to the bed at night with it fully charged and wake up with it at about 95 or 96%.
At work a fully charged phone just sitting on my desk drops to about 90% in only a couple of hours.
The signal quality in my building at work is pretty poor, so I'm guessing the phone is using a lot of extra energy desperately searching for a better signal .

Poor and searching for signal is probably the biggest battery drain there can be.
Get gsam. And after your at work a few hours, open and click on "phone radio". It will say how long your phone was actually searching for a signal. That's a huge battery killer.
The only cures, get on WiFi. Or go into airplane mode. Toggle off data might help, then you'd still get texts and phone calls.

I do have wifi on in both locations, so the wifi part of this doesn't help. I suspect data isn't the issue, just the cell connection. My old phone used to randomly reboot inside this building when trying to get a signal . I guess I should install gsam just to verify, but the signal is really the only difference between work and home, so I'm pretty sure that is the issue.

Usually battery drain from a low or bad signal is only a big issue while on data. On WiFi it doesn't affect the battery much , if any. Its from apps trying to sync through data on a bad or no signal. So on WiFi, that's not an issue.
At home I get fairly poor reception...sometimes only a bar...with some time spent searching for signal, but my battery times are at their best at home. On WiFi.
It could be a network issue. Some devices on networks can affect your device by spam polling your phone....might want to also get wakelock detector to see that. If the LAN is draining your battery, there will be wakelocks from it.
Try gsam and compare work results to home results. Especially good would be trying at least a few hours of total standby to see the difference at both locations. You'd have to reset gsam stats to start your standby test at all zeros though. A reboot will reset gsam.
Good luck!
Remove all google [email protected]%# ...
And disable autostart from programs like poweramp which start on boot...use romtoolbox and autostart manager
Of course, pay attention to what you're going to disable
If You will try and You have some doubt ask here
I use a lightweight aosp ROM, a minimal gapps package, stock kernel, disabled some programs from boot and run in background...and battery duration is good
Don't ask to us roms/kernel combo, please Questions like your are not allowed on xda
Always read the users feedback and make Your choice
And... My doubt..is it really needed to change the kernel ??
Give stock kernel a chance... That's all I can say...
And make sure to charge your phone the right way
Hi! Anyone knows if I can disable the processes that Viber starts every so often? Like the in-app processes, it keeps on running in the background consuming a huge chunk of my battery. I already emailed Viber about it but unfortunately they don't have a fix for it.

OK, I turned the phone off, charged it to 100%, then pretty much let it sit doing nothing after rebooting. After sitting overnight at home (where the battery doesn't drain much) the "Phone" app was way down in the list:

I think that is just the difference in signal quality. It seems to be pretty common to get degraded signal at work places due to larger structure sizes as well as more users per cell tower.
Phone Idle is from the voice network, Cell Standby is from the data connection.
Is it normal for Google Play Services to be running in the background always? The gcm and the location service is always on.

[Fixed] Standby battery drain

Hello everyone!
So this thread is for those guys that are still having the standby drain even after trying everything and got no help.
My Device Is not Rooted​Since last 2 weeks my device was having super standby drain and I couldn't help that.
First I thought that it was due to the battery wearing out. But I had this phone(exynos version) for around eight months and that is not enough time for the battery to drain out fast. So I started looking for the fixes in the xda threads but none of them had a mass effect on what i was suffering from.
Then I read about that app named the "Better Battery Stats".
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en
I used this app to monitor the usage that was being done by different apps.
Most of the battery i.e 61% was being consumed by the apps that were running in the background. And the second big consumer was the android system. So as was mentioned in most of the posts what I tried.
1) Settings> Display> Resolution> Fhd to hd
2)Settings> Device Maintenance> Battery> Save Power and All apps put into always sleeping apps.
3)Setting> Connections> Location> Google Locaation History and disabled it.
4)AOD Disabled.
5)Sync Disabled.
6)Wifi> Advenced> Keep wifi turned on while sleep and set it to never.
7) Reset> Reset network settings
8) Boot into recovery and wipe cache patition
9) Reset factory data(Wipe everything).
And after doing all these steps nothing much changed my battery life since when i after resetting my phone again updated all apps from play store and resetting battery got an SOT of around 3 hours.
Then I again started searching for the problem.
I installed the accuBattery app from play store.
https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en
And saw that phone was not entering deep sleep for hours that was causing the standby drain!
The major reasons for the drain were.
1) TOUCHWIZ HOME!
2) Google Chrome.
3) Facebook app.
To fix that I applied Lawnchair as my default launcher.
set the theme to dark. Disabled the location permission in the facebook app. And disabled google chrome.
Other settings that also helped were
Change the resolution to hd. Disable google location history.
And boom.... It worked Like a Charm....
Now to add an extra something to the battery life i switch to MID Power Saving mode. That Also helps alot when phone is not being used as it stops background data usage by apps.
Now the average sot that i get from my phone is around 6 to 7 hours.
And the phone sleeps like a baby. 5% Drain in 10h and wifi was on for the whole night. Deep sleep for 9h 41m.
PS: I use most of the time my phone for gaming and heavy usage.
Hope this will work for you guys too.
Screenshots Are attached for the proof!!
Thanks for this man
How are your notifications? I'm having a lot of trouble with delayed notifications, emails/messenger/etc just wake up when I take the phone and I don't even have to wait more than 5-10mins for what seems to be doze to kill everything.
I get whatsapp calls that I miss because the phone never receives it.
And STILL my battery life is far from great.. borderline bad I'd say. So sad
In settings go to device maintenance and hit battery you'll see an option for "always sleeping apps" enter any apps you don't want to run in the bsckground, which will probably be most of them. Saves a lot of data and a lot of battery.

Tips to For Increasing Battery Life on the Galaxy S9

Sooner or later you will find yourself looking to save some battery life. here are a few ways.
1- Disable Always-On Display
2- Put apps to sleep
3- Lower screen resolution
4- Use Dark wallpaper/ Shorten screen timeout
5- Auto Screen brightness off
6- Turn Wifi off when not in use.
The video shows how to do these if you're not familiar with the settings on the phone. Feel free to add to the list.
Honestly I don't get any better battery life when using the phone at FHD rather than QHD. If anything it seems to me that the software had become so optimized for QHD that it may actually turn out more SOT and general battery life times. But that may just be my experience, not sure

Also, never let the phone fall below 10% if you're able to control it.

Why not let it fall below 10% ?
I've yet to see any conclusive evidence that the battery life improves when you lower the resolution. Best argument I've seen for doing this is an improvement in scrolling and animations

And every year I laugh at it because every year people buy the best phone on the market and then make a list of how to disable everything and cripple it so they can squeeze another hour of battery life in.
I get it because I used to be obsessed with battery life but then I realized I have chargers, wired and wireless, everywhere.
Install BK Package Manager and disable all bloatware.
Quick tip for excellent battery life:
1. Go to wifi advanced settings and tell your phone to turn off wifi during sleep unless the phone is charging. ( helps a little)
2. Turn on data saver on your phone (so when ur phone is off it updates using ur data instead of wifi. since wifi is off during sleep if u did step 1)
3. Go into data saver settings and give unlimited data access to specific apps that you use such as Google play services( for account and data backup) messenger, gmail and any other important apps)
4. Go Into your battery settings, under unmonitored apps, remove every app sitting in there. Then go into always sleeping apps, and set everything to sleep except the apps you use the most and want to receive regular notifications for. (So of course Google play services and Samsung services if u use those to back up your data and some messaging apps and mail apps, messenger, snapchat etc)
If you do these steps you are preventing your phone from randomly syncing information. (The biggest culprits being the apps you don't really use such as the Samsung apps like AR EMOJIS, ant services, galaxy app store, etc).
this has saved me significant battery life. Averaging about 8hrs screen on time and get abt 2 days battery with relatively heavy use. (Inbox,YouTube, instagram, snapchat, bleacher report etc).
Hope this helps

Are you inside a building during most of the standby time? Or anywhere that would cause a weak signal? I found inside large building or places where cell reception is low causes a lot of battery drain during standby

No just no. Feels like i disabled every app there is. 4 hours sot. Maximum 24 hours total time. Draining 10% minimum during sleep if left unplugged for (7 hours) i put every app in sleep. Cant find samsung ar etc in (always sleeping apps tho) i set everything except for messenger. Snap.waze. bbs and spotify in always sleep. Still not sure it will work. Aod on. Auto brightness on.. maybe i shouldn't complain. But when people get 7 hours sot i feel like i need to complain. I had bad battery time with my s7 aswell.

I understand why you would be skeptical. i will try to get a screenshot the next time i have a chance.
Another thing I did notice is screen brightness is one of the biggest battery killers on the phone. Maybe try power saving mode but only use the -10% brightness option that should help a little bit or manage your brightness manually. Hope that helps
I'm pretty disappointed with the battery life on my S9+ to be honest. Today for example, with minimal usage, after unplugging at about 9:30 am I was down to 35% by noon.
I've recharged it and now left it sitting - it is consuming power at a rate of 1% per 10 minutes, just sitting on the table without me using it. I'm at home, with a strong 4G signal, WiFi router is in the same room, and Bluetooth is disabled.
I moved from an LG G6 to this phone because I was tired of the LG hanging and stumbling to do basic things, but at least the battery lasted a little longer - I could sit it on the table and I'd only lose a couple of percent over the course of a few hours.

I followed these steps yesterday. I took my phone off the charger about 11pm yesterday. Here is my battery info since that time
Ill tell you one way that brought my battery life to Awesomeness. lol Sounds like nothing But i deleted/Disabled FACEBOOK APP and right now im on
1 DAY 12hrs and 27 mins
WITH 52% battery left
Before I removed facebook it was about 30 hours or so.

Battery life considerably worse after update to 9.0

OTA update to 9.0 available a couple of days ago so I let it install. Since then, I've seen considerably quicker draining of the battery, with my usage of the phone being much the same as before. For example, when I went to sleep last night the battery was at 64%, and there were no apps running according to a swipe up from Home, but when I woke this morning, battery was down to 2%. I normally charge once a day, and previously the battery was hardly ever below 50% after 24 hours - I'm a pretty light user.
As an aside, with 9.0 there no longer appears to be possible under battery usage information in Settings to see the percentage of battery that has been used by the various apps and processes.

Ok here. 62% drop over night doing nothing suggests you have a rogue app in there. I'm assuming you have ok cellular coverage and nothing has changed there by coincidence. I would reboot and force close every app you have that's not essential overnight and try again. Swipe up from home and clearing those apps doesn't force close the apps. Greenify is an app that (in manual mode) will make it easy to select as many apps as you want and force close the lot of them. If that improves the situation you can then begin to work out which app(s) might be doing bad stuff whilst you sleep...
Battery on my P2 has significantly improved with Pie even if I didn't have any major problem with 8.1 either. Overnight drain 3-4%. After regular use after a full day I easily exceed 5h SOT. Everything stock with just Greenify in non root mode. I couldn't be happier, best Android release so far for me.

I've had my p2 installed with PIE for about 2 days now. I suggest giving it a week (which is what I'm doing) and then getting a full overview of how my battery is performing. Usually, after any major OS updates, being that apps are trying to utilize your resources and a new version of Android would try to allocate and learn your usage (in this case battery), you'd get a much better definitive idea of your overall performance.
I also think that since its now available, turn on Adaptive Battery mode. After a day of upgrading the OS, Adaptive battery at my 26 hr mark of upgrade said that one of my apps was taking in a lot of resources to be used in the background (ES File Explorer). I made AB to stop ES from taking battery resources.
So in conclusion, if it a week and then you'll be able to get a better overall understanding of whether your battery REALLY has gotten worse or better.
Hope this helps!
Interestingly, my battery was dropping really quickly too after the update to DP3, I switched off Adaptive Battery and it fixed the issue completely.
I tried it again with Android Pie and the issue resumed, so I turned it back off. Maybe try this too?

Exact same problem here after updating. Even tried a factory reset in case it was an updating issue. Same problem. My battery is currently at 43% 4 hours after a full charge. And I've barely used it. This is really poor.
No new apps installed.
My Oreo battery life was great. I'll try shutting off adaptive battery as suggested - but seems a real shame if one of the flagship battery saving features is doing the total opposite on Google's current flagship phone!
Doesn't seem to be a massively common issue so not sure if a likelihood of a patch either
Just a quick update - Google play services has now become the biggest drain on my battery, just as it was before I factory reset after the first install...
Anyone else had the same?

I had the same issue and did the same thing... until dp3 and my battery usage was terrible again even with adaptive battery turned off. I ended up turning it on again and after about a week my battery usage was back where it was before. So there doesn't seem to be a magic bullet here. FWIW app usage offered no insight as to what was causing the drain in the first place.

THIS.
I got like 8+ hours of SOT.... no mobile network though, all day wifi use only.
I have this issue. Dropped about 40% over night. I found that turning wifi off stopped the drain completely. I did not have this problem with Oreo at all so it's not the networks im connecting to. Weird thing is this did not happen when I first installed Pie. This started happening about 3 days into installing. Also, I put it in safe mode and saw the same drain with wifi on vs off.
Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
I've gone from draining 8-10% an hour (screen off) to around 2.5%/hour and from 1hr 35 total SOT to 3hrs 39 minutes with 32% left (and an hour of that was Google maps navigating, so a proper work out for the phone).
Do give it a try and let me know if it works for you.
Although there's room for improvement (idle 2.5%/h seems high to me!) and it's ludicrous that I should have spent several hours finding a fix for this on 100% stock android, I'm very happy to have a usable battery life back again...
Adam.
UPDATE: Seems like in the night I lost 40% again. Idle drain climbed it's way up to 5.6% in the night. Still an improvement from where it was before, but not quite as good as it first appeared...

@Burkules I drop 0.4 - 0.7%/hr over night with Bluetooth off/Wifi on/strong cellular signal. Much the same as it was with Oreo. Not quite sure why's there's such a big range (almost 2x) but either way it's ok for me. Did you try the technique above?

Cheers for getting back on this.
I left it on safe mode the other night and it still drained absurdly fast, which suggests to me it's a google system drain rather than rogue app, but will try again with app preview now switched off. Likewise will try greenify again and report back.

Likewise maybe app preview set to off will help me even more. If I recall correctly rogue apps can cause some google system apps to wake up, but perhaps not in safe mode...

So, switched off adaptive battery again (i'd enabled it after my short-lived miracle recovery the other day) and now I'm down to 4%/hour. Which is better but still really high for idling! Cleared cache and data in Google play services for good measure too as it still comes up super high on the list of battery drainers.
Booting into safe mode now to check the drain without adaptive there and will report back...
UPDATE: Exactly the same drain in safe mode. This is a straight up google problem....

Have you tried to force close every app you've downloaded too?

Haven't tried this - but if the battery drain is the same in safe mode (with only google/system apps running) I can't see how it will make a difference. Ill be in rehearsal for several hours today so will force close everything and will then be leaving my phone idling for a few hours anyway.
I signup up to the google play services beta yesterday, and google play services no longer appears as one of the top battery users... but the battery drain is the same and the numbers given in *all* battery apps (Gsam/accubattery/system) don't add up to anything close to the actual % drain. System battery displays 15% of usage (with 'full device usage' on show) when the battery is quite evidently at 48% from full charge. Total cluster****. So pissed off I updated.
Have you seen any improvement in yours with any of these workarounds?

Nothing to lose by trying. And as I said, Greenify makes it easy/quick to do. Force closing is almost as good as uninstalling those apps as the vast majority of installed apps won't restart or run in background until you use them for the first time again. In my experience, quiescent battery consumption (e.g. noticed over night):
Is vastly affected negatively by poor cellular signal strength. Marginal coverage can really drain the battery fast.
Gradually gets worse between reboots
Can be improved (once it degrades) if you force close all the apps you've installed, and swipe away the background apps just before you go to bed!
If quiescent consumption suddenly rises I can normally fix it by force closing all the apps (not being sure which was the one gone rogue/suddenly misbehaving)
At night I generally have excellent cellular coverage, good WiFi, and Bluetooth is off. NFC is always off
I don't enable sync on 2 of the 3 Gmail accounts I have configured
I disable notifications from any apps I don't actually need them from
Quiescent battery consumption is between, say, 0.4% and, 0.7%/hr at home, around 2 to 3%/hr when out and about which I put down to all background data being driven over 4G instead of Wifi, and variable cellular coverage
I've not noticed quiescent battery consumption change between Oreo and Pie, but this may be because I keep force closing apps at night and not giving adaptive battery (which I have on) a chance to have the same effect intelligently
Turning off app preview messages has made no practical different for me
I'm completely stock (stock launcher, not rooted, etc.)
If you can't fix it, at least a factory reset as the next experiment has the option to restore *most* of what was there before (so long as you have had the backup setting enabled). But because not everything is restored it's still a pain. And if that doesn't work it's another factory reset and test and then restore everything manually and gradually :-S. But I think you already tried that?

Hi guys,
I seem to have fixed my terrible battery life!
The below might be worth a try if you're still suffering from it.
I noticed in GSAM that RCSphone was the front runner in battery drain so did a little research and found this site.
SOLUTION: Turn off app preview messages (settings / google / app preview messages). Apparently its only function is to allow Allo messages to be received without the app. To me, totally pointless as i don't know - nor have ever met - a single person who uses it.
Thanks, just tried that as well and my battery has stayed resolutely at 68% on idle beside me for the last few hours, previously it had gone from 100% down to 69% in about 4 hours whilst similarly doing nothing.
