Terrible battery life probably caused by wakelocks

My battery will completely drain after <10 hours while the screen is off!
However I was able to find out thatquickgooglesearchbar is always the top app.
Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

I don't need betterbatterystats, I have battery Battery Historian, check the screenshots, It's clearly the search bar, on my other phone It isn't shown as a top app.
Also I went in the system folder /apps and there was no googlesearchbar, or in any other system apk remover tool, perhaps it was removed by another app, but it's still for some reason running.

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

Factory reset didn't do anything a few days ago, the results were exactly the same that was when my phone wasn't rooted, so I guess I should return the phone, and get a new one?

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Okay, I now have android N, and my battery life seems to be better, I will leave mobile data off. I will see tomorrow if my battery life has changed.
Do you think I should use Adaptive brightness for more battery life?

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...
What do you suggest I should do, I'm out of ideas at this point.

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.

Battery drain Oreo

I'm on Atomic and from the beginning I've got a problem with battery drain. This night I charged phone to 100% and during the night I plugged out the charger. NFC / WIFI / DATA / GPS OFF. After 1,5h from 100% battery drain to 93% !
https://imgur.com/a/kN5IO
From what I see WIFI running whole the time (even it was off) + phone is not going to deep sleep whole time but stays 518,4Mhz for long time
Any ideas what to do ?

I found that one of miui apps captures tcp dump. If you look under the /MIUI/debug_log/common you will find 2 PCAP files called tcpdump.pcap0 and tcpdump.pcap1
I think that miui findphone application creates it, because i have set disabled "find my phone" and cleared data of these app and files did not appear again

I'm not on MIUI.

So... you can have enabled "always scan" option in wifi setting.
https://www.reddit.com/r/GooglePixel/comments/5t93e4/turned_off_wifi_and_bluetooth_scanning_battery/

Ok I have disabled this option.
Lets see after some time, but I feel like something is keeping my phone awake and it is not getting to deep sleep all the time..

There is a module for magisk that force Doze.

Try turning off nfc.

I have installed crDroid and looks like drain gone. Just NFC has to be off.

Overnight standby battery drain

My pixel 3 XL has been losing close to 15-20% overnight. Didn't find any app causing the issue. Ambient display seems to be the largest user. Please see the attached screenshot.
Tried a factory reset but no change. I have an Exchange account on Gmail with auto push settings. Other than that everything else is normal.
Is this drain normal? Any suggestions to fix this will be highly appreciated.

I believe Ambient Display uses about 1% per hour, typically.

In that same screen you can use the 3-dot menu to toggle between "full device usage" and "app usage". You are on the full device side. As a baseline test try placing your phone in flip to shhh mode (setttings>>system>>gestures), and leave the phone face down overnight.

I put it on full device because app only mode doesn't show any apps at all.
Shhh mode turns on do not disturb right? I used Wind down from digital wellness and it also puts the phone on DND and greys the phone.
Still the drain is so terrible.

I tried disabling adaptive battery (interesting enough, it doesn't help to hibernate unused apps as much as it claims it would), turning off "system tracing application" in developer options too (not sure if its a big factor), left my phone on battery overnight then woke up ~7 hours later, lost 4%, unlocked for a few minutes then it dropped another 1% ---> total of 5% drain from 7 hours (0.7%/hour), overall pretty decent, with adaptive battery ON I tend to lose 1% per hour standby.

Wow that is interesting. Adaptive battery is supposed to be intelligently increase your battery life based on the usage.
It's the other way around here? ?

Default camera app battery drain

I recently bought this phone, I updated everything system, apps......the camera keeps running the background, even when I have closed the app.....
Problems does go away if I clear data of camera app...but I don't want to do this everytime.......I bought the same phone for my mum, and same thing is happening there too, on top of that in her phone chrome is consuming a lot of battery even when the phone is idle...... please help me out
Also I did try that restrict background activity but that option did nothing and the time on "while in background" kept on increasing
P.S location was off.

Never happened this problem to my European LG G7 Thinq (LMG710EM).
Anyway you have to turn off "background activity flag" to stop background activities of any app (do it for each app).
But consider also that the 7% of battery may be consumed just in that 11 minutes.
Shooting photo consumes a lot of battery...

After a week I have figured that you need to compromise on 2 features to get a good battery life ......1st obvious one was always on display, after disabling that, battery life increased a lot, but my idle battery drain was still 1-2 % per hour with wifi turned off.......2nd I disabled the double tap to wake (knock on) and hallelujah! Now on idle it barely drains 1-2% overnight.....
This is a great phone but lacks in the battery department...I mean, I don't mind disabling aod but double tap to wake is a great feature to have...too bad it drains the battery like hell

General No Deep Doze unless I disable Sim-Card

Hey guys,
I always wondered, why my phone wouldnt Deep Doze (according to Gsam). Be aware: I am not talking of the Deep Sleep (the CPU state, that is happening).
I always lost between 1,5 and 2% per hour overnight with the phone just sitting on the table, connected to the home wifi.
I disabled the Sim-Card (physical one, no e-sim) before going to bed tonight and my phone deep dozed now.
Yes, I am aware that there is this Mobile Network Standby Drain Bug. But since I disabled "Always use mobile date" in developer settings and was using WIFI during mentioned times, I dont know how that appiles to me.
Anyone has ideas?
Thanks!

Put it into airplane mode overnight and see if you get the drain. At least you'll know if it's a app or radio issue.

no offense dude, but did u read my post? see above.

What the heck is deep doze?

As stated above, it is a doze state that is being entered after the light doze. Check Gsam battery for your stats regarding deep doze.

I had the same problem, dropping 2-3% per hour over night. I turned 5G off, turned off 'mobile data always active' in developer settings and turned off adaptive connectivity.
Now im only losing .2-.5% per hour overnight.

Sounds like a bunch of hooey to me. Light doze, deep doze, medium awake doze.. come on look at your cpu stats and deep sleep when screen is off. If it's not deep sleeping overnight at least 90% then something is keeping the phone awake and you need to find it. Get BBS and look at your alarms and partial wakelocks. You have a runaway program that is constantly waking up your device. Mine was Mi Fit and I tweaked it so it's not awake all night long. Went from 1.8% / hour to 0.4% - 0.7% consistently.
@Napa7m Insta and WhatsApp shouldn't be doing it. Not sure about Telegram but I do recall some issues a year ago and I deleted it from the phone.

Either something is using up power when device should be deep sleeping, or it's just defective.
So he's right, monitor app usage and go from there. The built-in battery stats work well enough. It's how I discovered that 'mobile network standby' was consuming 20-30% over night with nothing going on.
DOn't forget to expand the 'system usage' at the very bottom of 'battery usage'.

I did and it still sounds like you're looking in the wrong place for your awake status. It's a background process that can't really be tweaked or modified on it's own. But alarms and wakelocks can that's why I said look there first. If your phone is not deep sleeping err.. deep dozing then something is keeping it awake. Find it and you're home free. What kind of deep sleep are you getting overnight?

I have about the same as you, mobile network standby around 20-25% overnight. I don't turn off 5G but I am connected to wireless with a very good signal. I have mobile data always active enabled as well as adaptive connectivity enabled. What I did to was turn off every adaptive setting in battery settings. Perhaps it's the wifi I'm connected to but I'm getting average 0.5-0.6% drain overnight. Deep sleep around 92 %. As I said, I did see some partial wakelocks and alarms when I was almost 2% / hour and either deleted the apps or figured out how to stop/slow them when not in use.

@bobby janow ok my man. first of all. a read for you, what deep/light doze is: https://www.andreasschrade.com/android-battery-optimisations
and no, its not the same as deep sleep. deep sleep is the cpu frequency.
my phone is now (out of a sudden) going into deep doze overnight, so that seems fine. also wakelocks couldnt have prevented my phone from going into deep doze, cause then, it would have also not gone into deep doze when I had my cd-card disabled (since there should be still wakelocks, when my phone is connected to wifi and all, right
since mobile standby is concerningly huge in the battery stats i assume its the usual culprit, but disabling adaptive connectivity, 5g and enabling that dev option does not help.
tho i am willing to find some wakelocks (since they seem to affect the device also a bit in terms of my standby drain). according to gsam everything is fine in that department, cant really find unusual wakelocks. does bbs show more there? im not very keen in running an adb to make it work...what does that command line do exactly?
thanks!!

@xflowy BBS needs 4 adb commands and it takes about 30 seconds to complete with a copy and paste from his thread. It has two wakelocks stats, kernel and partial. The kernel ones are meaningless to me but the partial tell a lot, you'll see. Also just as important is the alarms stat. It gives you that amount of time an app is firing i.e. wakeups. Check it out see if it helps you. Thanks for the read, but it's beer day today and that looks like it will take all my concentration. Lol.

@xflowy On first read it looks like battery optimization regulates doze mode, right? I mean that's really the only way?

It also happened to me after many tests I have managed to solve it, deactivating the sim card and esim, and restart, then activate the sims and drain solved, it already goes into deep sleep.

I have the exact same issue. I thought I'm the only one. But I'm unable to resolve with this by disabling sim n reboot method. Can anyone suggest if it's hardware fault ?
