I have been obessing over my battery stat page and am trying to figure out what exactly "Android System" is. It is usually consuming the highest percentage of battery power. I have tried everything to figure out what action exactly makes Android System get added to the battery stats page. I have disabled everything, every radio, syncing, deleted all widgets. I hardly have any apps as it is. It just seems rather inconsistent because sometimes Ill check the page after making a call and will find that Voice calls has consumed a small percentage of battery and Android System isn't even on the list. Other times I will take it off the charger and make a 30 minute call, but when I check the stats page 70% battery was used by Android System and only 3% was Voice Calls.
Can anyone tell me exactly what triggers Android System so I can make sure I cut down on its battery usage in any way possible

I assume you are looking in the settings > about phone > battery. You can select android system also and it will tell you more info.

Did a battery calibration and now android system isn't the number 1 thing consuming battery as usual. Weird:

This seems to be more in line with what normal battery usage should look like in my opinion.

I had this problem too until I did a calibration. Now cell standby consumes over 50% of my battery regularly, with android system consuming only 2%.

Its still occurring
What would you guys do?
Android system will occasionally use CPU as well, as shown in the following screenshots. Also! My good buddy let me see his Droid x recently. He had 42% battery life left and android system had only taken up 4% of that.
I'm pretty upset about this.

If you asked me I would say all your values are a little screwy. Do you even turn the screen on, on your phone and use it? If you use your phone the Display should be by far the most used. To me it looks like you physically use your phone very little. That is why Phone idle and Android System seem to be the higher numbers.
Guessing you have many accounts syncing in the background. One of the biggies for Android System. So its not that Android System is using so much, the rest of the processes are using so little.
Oddly enough the same thing started happening with my phone recently too.
@Agoattamer
The system wouldn't eat most of the charge in less than 8 hours in normal circumstances. Also about your question concerning accounts, while I'm not seh6183, personally I only have my email account synchronizing and the very same thing happens.
Something is causing the CPU to remain awake, in my case stuck at 800MHz.
The factory reset will most likely solve it, but it'd be best to find the culprit to just try and rectify a specific anomaly rather than reinstalling the whole system.
Has recently any core Google apps been updated? Email, Maps, anything?
I do agree that in 8 hours of non physical use your battery should not be going dead. So I couldn't sleep last night and I did some google searching. Here are some things I found out.
Do you have Googles Goggles installed? Seems it may have a bug where it keeps the camera on even when the phone is supposedly asleep.
Seeing that seh6183 always has his wifi active maybe it has something to do with wifi. I found this from Juri's TechBlog
couple of days ago I finally got the eagerly awaited system upgrade to Gingerbread on my Nexus One. The update went pretty well, although some Nexus One users reported about problems with the updating process. The only thing I noticed is that Dropbox didn't work after the upgrade.
A re-install solved the issue. All-in-all Gingerbread is great. Beside UI enhancements it feels also faster than Froyo. However, after trying it for two days now, I noticed a substantial increase in battery consumption. By looking at the system battery stats (Settings -> About phone -> Battery use), Android System was listed to consume 23% of the battery .
Apparently the problem is a bug in Gingerbread version 2.3.3 (you know there is 2.4 as well) on how the system handles the Wifi adapter. If you go into your Settings -> Wireless & Networks -> Wi-Fi settings, press the menu button and click on "Advanced", you'll see a menu entry "Wi-Fi sleep policy". Gingerbread seems to have a problem when that option is set to "When screen turns off". While that may sound to be the most energy-saving option, the bug turns it into a battery killer. If you switch the option to "Never", the Android system will only consume ~3% in the battery stats.
Obviously, in addition to this, the best battery saver is to just turn Wi-Fi off when you don't need it . Caution, if one of the future updates fixes this problem (which I strongly hope), you have to set the option back again.

Something I didn't see but killed my battery on my windows mobile phone was instant messengers. Do you use any apps that are for instant messaging.
Found this thread also talking about the same bug with wifi
http://code.google.com/p/android/issues/detail?id=15057
So it seems that if you (cmdr001) also are a full time wifi user, you may be affected by the same bug. Check your wifi sleep policy and adjust your settings to "Never".
Install a battery monitor app from the market or spare parts to see what is using your battery. Install Juice Defender to stop all that excessive useage.
Excellent find!!!!!
Just switched the sleep policy to "never" (which ironically I've always used until very recently). Ill return with results after about 5 hours. The only thing is that I'm on android 2.3.5 not 3.3 so we will have to see if the bug was affecting me.
I also don't have Google goggles. And to the above poster, my phone regularly went into deep sleep so it wasn't my CPU that was staying active.
Oh and I've been using watch dog to look for rogue programs for the last 24 hours. I haven't got a single alert.
Sent from my Microwave
I guess the first question should have been what ROM were you using and to try a different one then. Needless to say it still has 2.3.3 components in it. And if you recently changed that setting then my bet is thats the issue. Goodluck.
Watchdog may alert you if you are using too much cpu at one time but I don't think it will let you know what is constantly using the cpu.
Ok there's a glitch somewhere in the battery tracking. I just checked it and android system was consuming 12% battery. I placed one 17 minute phone call and re checked it, I then had 57% android system consumption.
No way.
I'm using a cm7 nightly and I'm about to flash the stable version with a different kernel. Ill do a full wipe as well.

You could check your wakelocks.
After recharging my battery to 100% and wiping the battery stats, my android system consistently uses 2% of the battery, while the display sucks up around ~40%.
Hi,
First post here, so I hope I'm posting at the right place.
Just bought an unlocked Samsung Omnia W (Focus Flash stateside) around four days ago. I didn't notice anything about the battery life the first two days since I was using it quite heavily and felt the rapid discharge was normal (the usual rigmarole- everything turned on).
Last two days, I've started using services more selectively, and still see my battery discharging at an alarming rate. I'm talking 5-8% in an hour with barely a minute or so of the screen being on for checking texts and sending a few.
I've disabled everything- location services, ALL live tiles, WiFi, Bluetooth, even went as far as to disable 3G and switched to 2G. I switched back to 3G because where I'm at I get a full 3G signal but a very light 2G signal. I've put off all background services (Gmapps was the only one, I uninstalled it). Turned off Xbox Live connection as well. Turned off facebook chat. Removed the People Tile. Three email accounts set to sync "as mail arrives".
I noticed the battery saver screen was showing me only 3 hours on 48% charge. I then completely discharged the battery through WPBench battery test (which showed 52 minutes starting at 25% battery life). Now, I've been charging it for an hour or so, and the battery saver screen shows 22% and estimates only 1 hour as the run time.
Is my battery defective? The WPBench time of 52 minutes for 25% seemed par for the Focus Flash (Engadget gave it a run time of 3 hours 30 on WP bench I think), but this fast discharge is really baffling and makes me kind of afraid to use the phone too much. I've heard the Flash has stellar battery life, so if anyone can throw some light on the matter, that would be great.
By the way, updated to 8107 two days ago through Zune. Normal usage consists of 30-40 texts a day, an hour of calls max and maybe 10-15 minutes of browsing. Battery saver screen usually shows only 9-10 hours on a full charge, though it does last a bit longer than that (14-16 hours). I'm sure such light usage doesn't warrant such a quick discharge.
I apologize if this makes for a really long read, first time here.
Thanks.
First, battery saver gives times based on previous data so it will get more accurate with time. Second, the battery will get better after about of week of use, it takes a little time to 'break in.' Third, if you are in an area that has poor reception your phone will try to find a signal a lot more and this can drain power quite a bit. Fourth, try returning everything to normal as far as background agents, email sync, and data settings ect. but turn 'battery saver' on after a full charge. If you still have bad battery life then perhaps somethng is wrong with your battery/phone.
EDIT: if you are using 'light' as your theme you will use a lot more power since amoled screens work best with black bacgrounds since the black areas are essentally 'off'
Been using a dark tile. Let's see how it handles with time.
A lot of my friends with Android phones simply keep data off since their batteries barely last if it's on, do I need to take any such harsh measures with WP? I hope not, I like my mail to arrive immediately (I have set sync on "as mail arrives").
Push email (the "as mail arrives" setting) is actually a very substantial power-drain. Setting it to even just every few minutes (5? 15? I forget what the next level down is) will help.
I may be wrong, but won't it cost less battery if the phone was getting push mail, say, three times a day for 3 separate mails as compared to checking every hour 24 times a day?
Why would you think that? The phone doesn't magically know when email is available for it, to only wake up the email sync process and data connection then and leave them off the rest of the time. It has to maintain a continuous (or nearly - often enough that you don't notice the gap) connection to the server. Even idle, any kind of live data connection uses more power than a process which stays suspended 99.9% of the time (meaning 86.4 seconds of activity per day, which is probably a pretty good estimate actually).

I thought push email and other kind of push notifications were sent from the server to the phone, and so the phone didn't have to be constantly checking for email updates...
The phone needs to be listening for those notifications. That requires running the radio (for data) at a higher-than-minimum level. Push notifications have a similar impact to push email, in terms of battery life. It's not hugely destructive - I have two email accounts that use push, and still tend to get through the day and then a bit just fine - but it does impact the battery life.
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.

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.

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)

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...

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...

@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?

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.

Hi
I've got a brand new PH-1 and haven't yet had time to set it up properly, only started it up, let it update software and used for an hour or so before testing the idle battery drain.
I haven't installed any apps or changed any settings other than to disable the google app (to prevent it listening for or responding to "ok google"). I tried out the 360 camera, signed in to gmail and browsed a few websites, before charging back to full and restarting the phone before this test anyway.
But leaving it idle with the screen off and with phone network disabled (there's not even a SIM inserted), only wifi on with good signal, it lost 65% battery in under 22 hours. Screen on time was less than five minutes.
Is this a hardware issue I should RMA, or is it considered normal? If this is normal and there's no easy fix, I'll probably end up having to return the phone anyway for a refund, because if it can't even last a day and half in idle there's no way it would last a reasonable amount of time with normal usage.
Any ideas?
Thanks
Since there isn't a sim card installed, try going to airplane mode and then turning WIFI on.
I am getting about 1.2% drain with cell network and wifi enabled along with all my standard apps installed.
On a typical day with 1-2h SOT, I usually have 60-70% battery left at midnight. I'd try to reset the phone, and then testing again - occasionally a system update will end up doing something funny
I left it overnight with airplane mode on, so even wifi was off, and it's a little better but not by much. Screen on time was one minute.
With airplane mode on, screen off, no dodgy apps, the phone really shouldn't be doing anything to drain battery.
I'll try a full factory reset and see what happens.
Just to follow up, a full factory reset seems to have fixed the issue. Even after doing the same things I had done before (connected to wifi, updated, logged in to gmail, etc) the battery now drains at a much more sensible rate.
Very strange that a factory reset made a difference since it was new from the factory when I had the issue, but I guess something strange happened in the update like dsip suggested.
Thanks for the help!

That's ? percent normal behavior. Anytime you flash a ROM (new phone =new ROM) you need to wait a bare minimum of a charge cycle (more like three in my experience) before you get the slightest idea what your actual battery drain is going to look like. think of it like breaking in the engine on a new car.
