odd battery usage stats, poor battery life

hi
i have a new (3 months old) unrooted nexus 5 update to latest OS version which is showing some very odd stats wrt battery consumption.
first i had heavy battery drain but then i disabled the scanning options in the location menu which helped. but still even with brightness at only 18%, battery saver on 95% of the time, location & mobile data off all the time & wifi only used for short bursts it still seems to drain quite quickly.
app usage stats as reported by the inbuilt battery stats option differs quite a bit from other battery management apps (du battery saver, battery doctor, gsam battery monitor)
for eg. inbuilt battery stats doesnt even show wifi consumption in the stats even if i use it for few hours (then suddenly one time it showed up with some excessive consumption stats - 1500mah for 2 hours usage; photos attached). very often it shows gravity screen app as the biggest consumer of battery while other apps show gravity screen as consuming very little power. otoh gsam shows battery doctor as consuming the most of all the apps.
what could be the issue?
gsam shows average battery life with screen on as 3h 42m. is that ok?
was also wondering if the optimization options of the battery management apps work or are they gimmicks? for eg both du battery saver & battery doctor show 'x' number of apps consuming power in background & when you press the optimise/close apps button it shows some cool effects of shutting down those apps but you come back after a few hours & the same apps show up in the running in background.
also, the front camera is very grainy. cant believe its that bad in what was a flagship phone. is it just my phone or is that the how it is for other users?

anyone with any inputs?

You got nearly 5 days on a single charge??? Yes, your battery consumption is fine. Nearly 4 hours of SOT is fantastic.
The graininess of the camera will depend a lot on the lighting. Unless you have a light shining directly on your face, the picture is probably pretty dark. That said, it's "only" like a 3MP camera. It's well known as a sub-standard front camera (I'm not a selfie machine so I don't really care). When you think about how microscopic the light sensor is on the front camera, it's no wonder the picture is grainy.

thanks for your reply exninja
that 5 days was a one time thing where i barely touched the phone & then only to test it. i wish it were that good LOL. normally i get about 2 days with very conservative usage (brightness at only 18%, battery saver on 95% of the time, location & mobile data off all the time & wifi only used for short bursts, 0 talktime)
is 4 hrs SOT that good? i see a lot of people getting 5 to 6 hours + & that too without those conservative usage patterns.
the thing that got me worried is the strange battery usage stats reported in the stock settings.

Honestly I wouldn't worry that much about what each app says is using energy. They're each consuming very little anyways. I'm not familiar with gravity screen so I wouldn't know about it.
I haven't heard of many people getting 5-6 hours of sot, especially since lollipop. I got 4 hours on KitKat, then dropped to 3 or less on lollipop. Now it's usually around 2 hours.

First of all, just to let you know, recently Google Play Services have been acting up. Sometimes I get normal battery drain overnight when I sleep, and sometimes it drains like crazy. For now, there is nothing we can do about Google Play Services.
However, if u noticed that WiFi has been turned on the whole time via the battery history chart, despite the fact that you did not even turn on WiFi at all during that period, then this can only mean one thing. You must have enabled WiFi Scanning (the famous Scanning always available bug in Lollipop & KitKat).
To disable WiFi Scanning, go to Settings first. Then on the top of settings, there is a search bar. Type in "Scanning".
Then u will see the following options. Make sure u disable WiFi Scanning.
Having said this, there is another annoying bug. This bug is when you have left a WiFi hotspot and forgotten to turn of WiFi. So after awhile u realised it and u proceed to turn off WiFi. But hours later, u check your battery stat, and it still shows your WiFi have been active the whole time despite turning it off. For this, the only workaround is to reboot the phone. To avoid this bug, always turn off WiFi b4 u leave the WiFi hotspot area.

@pcphobic i have wifi scanning off & i always remember to turn wifi off when not using it so that second scenario is not an issue with me

The other solution that I can offer is under Location settings, go to Google Location History and make sure it is turned off.
You can still use GPS based apps with Google Location History turned off.
I suspect that if u find intermittent wifi showing up in your battery history, it could only mean that Google Location History is periodically waking up and using wifi to get an approximate location. I used to get this until I turned off Google Location History.

Stop wifi drain on standbyI

I just got an LG V20 which is good on battery when in use but sucks when not in use. The culprit is always wifi. I just discovered the root cause is Location services that is using wifi to get locations even when wifi is off.
To stop this, go to settings->location->scanning.
Uncheck wifi scanning. For good measure, uncheck bluetooth scanning.
Go to wifi menu ->advanced-> keep wifi on when screen is off
Change to never or "only when plugged in"

Hi,
thanks for your helpful tips..
So out of the 3 tips you have:
1. Uncheck wifi scanning
2. Uncheck bluetooth scanning
3. Turn wifi off when screen is off
Any idea how much does each option save (if you've quantified)?
I'm happy to follow points 1 and 2. I'd only do 3 if it really helps a lot, because most apps would use data if wifi isn't available to periodically phone home.

I have always been dissappointed with my V20 standby time.. I had all of these settings on.. so i'll see how she does now they are off.
Thanks!

My standby time is from 0-4% over 8-9hrs. I really cant complain.... but the phone is facing down.

I wasn't aware of the wifi location scanning, and the bluetooth scanning. Giving it a try as my standby time has been horrible lately.

I am also facing severe battery drain on my LG V20. Battery easily drains by 5-10% per hour even when the phone is lying idle with screen off. Major culprits are 'Phone Idle', 'Android System' and 'Android OS'.

Try what is mentioned here
Post your screen shots here and tag or quote this post

As a side note, I've found that using wifi and cell data to help location services causes maps to scan these options and slow down (maps keeps saying every 5 to 15 seconds "searching"). By using gps only, the maps app is faster and less battery drain.
Obviously if you are indoors you need the help of wifi or cell data. But in the car or outside it is unnessary.

Thanks for your tips it's very good for my life battery. :good:

I tried as suggested in the post you shared. Once the Bugreport was generated, I got a notification to click it to share. But, upon clicking nothing happened. I did not get anything (no pop-up, no options) further to share it. I tried thrice but, every time same end result.
How can I access the Bugreports generated on the phone?

- see the cpu running, userspace wakelock & screen on lines. They seem to match. Screen is on, cpu working with userspace wakelock. Close to 7pm the screen is off but the cpu is running, because you were listening to audio. I don't see a problem here. Looks normal
- you screen off discharge rate is 2.56%/h which seems a bit high. If you were streaming audio this might add to it. Do you have the second screen on when the main screen is off ?
- somewhere around 12pm you are using data for about an hour. Mobile Signal strength isn't very good, mostly yellow. What i don't understand is why your wifi is also on ? and this is in an area where wifi signal is bad. Both of these will add to drain. And in two hours your battery dropped from 70 to 40
- little after 1pm you're on wifi for a couple of hours but the signal is weak
- around 5pm you're back on data streaming audio and battery takes a nose dive here. Down 30% in like an hour. Were you moving ?
- then you charge up to 85%, doze kicks in which is good, if there was app drain doze would not come on, for the next 5h without use, you lose about 5%
- the part i don't understand is between 1am & 6am, battery drops 10% yet full doze (blue) is on. So there is some activity going on there. What ? sync ? updates ?
Not sure about the aggregated stats as you've recharged up and run down fr a second cycle so it could be your off screen drain is twice as high because of that
charge up again, go through your day and save log when you're at 5% and lets see the two screenshots from just one charge cycle

Thanks a lot! Please find my answers in sequence.
- I listen to music while going to work. But, that is, till 8:30 AM only. Yes, I have 2nd screen ON when the Main display is OFF.
- I watch stored videos during lunch (12-1pm) for around an hour but it shouldn't be using data as I am playing stored videos.
- Around 5 pm, I leave for home. Again while going home I listen to music for half an hour.
- I have no Idea of what is happening during Night because I just leave it and don't use it until morning. In fact, I have scheduled the 2nd screen to be off between 11 pm and 6 am
I will try to run a proper cycle as you have suggested and will recapture the logs.
I understand the battery dropping while I am using the phone (listening to music/watching videos/browsing/anything else). What I don't get is the battery dropping insanely when I am not using it. For example, once I reach the office, I stop the music, kill the music player and just keep the phone aside. After 1-2 hours, as I check my phone I find battery dropped by 10% or so! It's the battery drain while my phone is just lying idle that is troubling.
Also, I have noticed that once I charge my phone and then leave it (Not using it) the battery drain is minimal like 1% per hour. But, once I run some app (music/browsing etc) for a little while and then leave the phone, the idle battery drain is pretty high.

Same sequence
- When you have the second screen on, is the phone facing up or down. What i notice with that second screen is it ignores any brightness settings. If the phone is face up and pointed at a light, the second screen becomes very bright. If its facing away from the light then it dims. Depending on how your phone faces you will either have more or less drain here, without doing anything and phone just sitting there. Typical overhead with second screen on and normal brightness ie not too bright is around 1% per hour. This could be adding to your off screen drain. Why not try a couple of cycles. One with second screen off and another with second screen on. Just to see how your off screen drain rate is like.
You say you listen to music only upto 8:30AM, take a look at the audio line. Can you see audio triggering ? there's little blips there after 8:30AM which continues till 5:30PM where its solid. This is your ride back where you listen for an hour. The 5:30 audio is ok but the blips in between are not leaving aside lunch video. Each time there is an audio blip there is a wakelock. Pay attention to the duration of the audio blip, if its a few seconds it could just be notification, but if its longer, does it correspond to your use.
Now look at the top app line, try to find which apps are running when audio triggers. To do that hover over the top app line which coincides with audio when you were not listening to audio. You will see a popup screen with a list of apps. Or check History Stats - TopApplicationSummary for a table, screen shot that and post
Do you use a lot of widgets that update in the background ?
- something was using mobile data when you were watching stored videos at lunch. Take a look at the'mobile radio active' line and you see activity there around lunch. Your wifi however is off and not running. If there were any apps running they were using mobile data, this is extra drain
- take a look at the line that says 'foreground process'. it's pretty solid right through both your runs. The only time it stops is when you recharge. This is a hint something is up. If you hover above it what does the popup say ? try moving along the line and observe whether the information changes
There shouldn't a foreground process running when you're not using the phone. Maybe if you can screen shot, the table that displays under History Stats - Foreground Process Summary
Scroll down and under the graph and on the left you will see three headers with twisties, System stats, History stats & App Stats
Hold on to your bug report files and they will be useful to verify if any changes you make take effect or not
- 1% per hour corresponds to second screen on, with it off your drain would be halved. However having drain after leaving a music or browsing app isn't good. It means a wakelock was caused and its not releasing so doze can't kick in. So battery will drain. If the phone is shaking, say in your pocket as you walk around, full doze won't kick in either
Which social media apps do you use.
Stock launcher or other if so which

I've found just buying a new battery off of ebay for $10 is the the easiest way to gain back that extra hour of on screen time and extend stand by. That's why the phone was made with a removable battery. I have 3 of them and don't need to touch a charger for a week. and when the time comes to charge the batteries, just put them in the charging docks and done.

[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.

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.

Battery Drain Diagnosing

I have had a battery drain for several weeks now. It isn't to severe but the biggest issue bothering me the most is at night it is draining about 5-6% even with battery saver turned on. It used to be that in normal mode, the battery would only drop 2-3% over night. I do not charge at night.
I am fully updated and I even reset the phone to factory 2 days ago and the issue still persists. Nothing seems to stand out in the battery stats with regards to apps sucking battery %. So I think this is an issue where it is not going into Doze or Deep Doze but I dont know how to determine that.
Any suggestions how to find the problem?

(on android 10)
When you wake up in the morning...
Go into "Settings"
Then "Battery"
Then click the top right three dots
Then select "Battery Usage"
It should show you which apps used the most battery during the night.

I have done that. No apps appear to be doing anything unusual. There are no battery hogs showing up. Not even excessive google services usage or anything. That is why I think this may be a situation where it isn't going into doze or deep doze like it used to but I dont know how to check or monitor that. that info doesn't show in battery stats.

I never heard of this doze/deep doze mode - where did you see this?
I ask because I typically get 10% loss overnight with what I thought was very good because the pixel often then calculates I have 2 days of remaining battery life with that stat.

You can google it as there are tons of articles about it but here is some insight into it from the developer side: https://bignerdranch.com/blog/diving-into-doze-mode-for-developers/

OK, so it says in order to go into deep-doze, the phone:
1) Must not be charging
2) The screen is off
3) The phone is not moving
So, during the night, are all three of these conditions met?
Also, the device will come out of deep-doze if an incoming push notification is received - could one of your apps be receiving push notifications during the night?
Also, "Any process using a foreground service is exempt from Doze Mode effects, which is key for long-running applications"...do you possibly have any apps that have a foreground service?

Have you tried to switch off Bluetooth, it has a huge impact on battery even if not in use.

I've used apps before. Can't remember but gsam might be one...
It's possible to identify apps that are holding wake locks. That's the first place to check for battery drain.

I always keep WiFi, bluetooth, NFC and location off.

all the apps I can find to track wake locks seem to need ROOT. I'd rather not do that as then I lose OTA updates.
After some extreme disabling of user app, system apps, services, etc. I finally got back to 3% battery drop overnight. I'm not sure which one was the culprit yet but i'll start enabling things as I need them and keep monitoring.

I'm having heavy battery drain. I already charged to 100 and less to 30 minutes i lost 10%.
It began since last update on my case.

After you see a big drain, DON'T plug in and...
Go into "Settings"
Then "Battery"
Then click the top right three dots
Then select "Battery Usage"
It should show you which apps are to blame for the drain.

Gsam needs permissions but these can be set with USB debugging, no root needed.

So one thing I have learned is that it appears every time I reboot, gsam thinks my wifi is on even though I have it off. If i turn it on and then back off. Gsam now says wifi is off.

So i got through the night at 3% battery drain but now I am realizing that my phone will not go into deep sleep during the day. Any suggestions how to fix that?

According to the details in the link posted earlier, it will never go into deep sleep if the phone is moving.

I leave my phone sitting on a desk all day. There has to be some Android services that only operate during the day but i can't dtermine what those might be.

Was gsam able to identify which app was holding a wake lock?
Or maybe triggering frequent wakeups?
Both of those would prevent doze...

Battery Guru is good for chasing drains (with ADBs), add BBS + adbs and you can find anything using them together!

Google play services mostly. There was a large amount from "Adaptive connectiviy" but when I disabled that those went away.
