I alrdy posted a question about this but I figured it out myself in the meantime (i think):
My phone has/had a very high battery drain and I was wondering why. So I kept watching the battery history over and over.. and yesterday I recognized that sometimes the phone doesnt seem to go into sleep mode. When you see the battery history, the "Execution" % (the thing that shows how much % of uptime the phone has been executing/running something) went up even when the phone display was turned off. This meant that some process had to be running.
So after watching the thing closer for a while I noticed that its the mediaserver process. Restarting the phone did help. But after a while the problem was back. So after some more investigation I found out that (in my case) Fruit Ninja was causing this. When I played it, afterwards the mediaserver would keep running. I tried to kill the process, both in app settings, and even in terminal mode, but without sucess. Only restarting the phone did help so far.
..
So if you having very high battery drain you could look into this. There might be other apps out that cause this too.
To see if thats the problem check battery history and note/remember the actual execution %. Then turn off display/let it lie for 5 or 10 minutes, and check the % again, if it went up this or a similar problem might cause ur drain.
--
If someone can figure out a way to restart/fix mediaserver without restarting the phone it would be awesome.
To view the process in terminal:
ps | grep media
tried killing with -15 and -9 both didnt really work, although the response was that the process was terminated/killed. So maybe there is something else wrong than the process itself.
You might be on to something.
In the last few days I have been seeing horrendous battery drainage.
I charge my phone in the evening and next morning it is at 40% left!
I also thought it must have had something to do with the phone not going to sleep.
Battery history tells me "Time without Sleep: 4d 6h", in the last 110 hours since restart!
So something is preventing it from going into sleep mode.
Thanks for sharing, I will see if I can test it a little more.
for me exactly the same,
mediaserver up and ruining in background after playing ' pocket legends', restart did help.
running on original samsung rom 2.1 jm2, just rooted.

I can confirm this problem (generated by Fruit Ninja apparently). killing the service with the terminal emulator (using root and the pid) and then restarting it seems to work, but it's not really user friendly.
Should find a way to avoid the mediaserver to loop or at least automatize the process (for example with some sort of background script that kills/restarts the mediaserver if it has 5-10%+ cpu usage for 5 minutes or more pooling every minute)
Edit: killing the process and restarting it brings it to low cpu usage, but I'm not shure the phone goes back to sleep mode as it should
Edit2: I don't really understand... I had the phone on for 2 days, then I've started fruit ninja and the mediaserver went crazy. Killed it several times and everytime I've restarted the game the problem come back (and this is all ok).
I was pretty shure the problem was in some .png in the .apk file since there are people with a similar problem caused by corrupted images or videos, so i extracted them and opened one by one: no problem at all.
Restarted the game, killed it.. and the mediaserver was ok at 0% cpu usage
I guess there is a combination of more elements here.
I tested the game, turn off, 7hrs of idle later I lost 40% battery!
The same problem here ! I need to charge my phone every night. If i leave the phone over the night it may take up to 30 % of the battery
Hoi,
My batt. drained in less than six hours, so I tried different methods to get around this. Switching 3G off and so on. But nothing helped in my case! So I went back to the store, explained the problem... The guy came with some of the usual excuses.... So finally I've dicided to buy a NEW batt. With that all my problems just went a way. I average 2 to 3 days with moderate use. Checking mail, some news,Radio for like 1 hour. About 10 min. Call time and a few other things.... So a new batt. solved my problem. Just incase a bought a spare.
But aside from this, Samsung should look into issue and handle the complaints seriously.

Trying to figure out what was causing excessive battery drain on my phone, I downloaded SystemPanel and had it log overnight. I read that when the phone is unused, none of the apps in the "Top Apps" should show over 0.2%. I left my phone on the charger all night and the "system" app sucked up 1.2% completely unused. Apparently there should also be some kind of standby app showing up, and that is nowhere to be seen. I'm running Nero v5. Anyone know what could be going on?

In my experience, System Panel is not the culprit when this happens. I've had success with getting 0% battery drain on airplane mode overnight, and always w/SP running. (It's inconsistent, though -- I actually tried it just last night, and Market ended up jacking the CPU all night, even though I had killed Market hours before bed. Don't know why this happens.) I actually leave SP Monitoring on all the time, and generally get (what I consider to be ) great standby battery life.
To the OP: what were the top apps that were running (at more than 0.0%); and were they burning CPU the whole time? If an app/process is running the whole night, it seems to also "trigger" System to burn CPU -- but the app itself is the "real" culprit. (Pls keep in mind I know none of the technical details; but I've experimented a lot w/this.)
EDIT: sorry, just read yr post more closely. To address two more points:
(a) re: the "Standby" process -- this rarely pops up for me, even on the occasions where I do get a totally placid phone overnight w/no batt. drain.
(b) re: I left my phone on the charger all night -- try it without doing this (stay off charger & use airplane mode), and see what happens. I haven't had good luck w/leaving phone on charger: I wake up to same thing -- System jacked up -- and end up needing to power-cycle phone to get System to settle down.
(By the way, I'm totally stock JI6, and so can't address Nero etc.)
The standby process ("suspend") should always be near the top of the list if your phone is truly in standby in a given 8 hour period.
notverycreative - system always uses between 1.9-2.5% for me. It's the system processes and regular apps that you should pay attention to. Once I used Titanium to freeze Media Hub, the DRM Protection Processes, WiFi Calling and some poorly coded apps, my battery life improved significantly.
Here's some screen shots from mine over night.
Alright, I'll try doing all that tonight. I just flashed Bionix V so I lost my data from last night, but I'll try to recreate it tonight. I did get rid of the DRM processes and Media Hub, as well as SNS sync. I never installed WiFi sync for that exact reason.

Just spent the night on flight mode and nothing took more than .1% battery and the battery didn't drain much at all, as the meter read 90% before and after I slept, which was about 6 or so hours. It may have something to do with flashing Bionix, but regardless I am happy thanks everyone!

Hey all, I would like to get an idea of the average/normal battery life you are all getting with the TMobile MyTouch 4G. I'm originally a proud owner of an HD2 & also own a Droid Incredible, but a family member has this new Tmobile phone & they are not having the best experience
Basically, Battery is running out, literally from 100% to 0% in approximately only 5-7 hours. What kind of use? Almost none! 3G Data On; GPS, WiFi, Bluetooth all Off. No navigation. Less than 3 hours talk-time during that time. Display on Automatic brightness, with timeout at 15 sec.
She is at work during most of this time so no heavy data usage, & I know so because she's on the 200MB plan & "MyAccount" reflects light data use.
Phone is completely Stock (no overclock, stock kernel, not rooted, etc).
So is this terrible battery life normal? Or would you all say there is something off with this particular phone?
There is a task manager installed set to kill unnecessary apps on screen off. I've gone over all settings at least 3 times. Still dies in less than 7 hours. I dont get it. So that's most of the info, anything else I forgot to clarify let me know!
Thanks!
If you turn off the mobile network and stop all synching if you don't need it the phone should last you a very long time, the data connection saps up a lot of battery.
First of all, UNINSTALL your app killer. It does more harm than good.
Second, it would be good to root your phone, and uninstall unnecessary apps. (amazon mp3, games, etc etc... all the bloatware.)
Third, install setCPU from market and set up profiles as recommended on XDA. (search)
Fourth, set USB debugging ON, stop all sync incl background data, display at auto brightness.
YOU have to remember that battery life really depends on usage, and LOCATION.
During a work week, I recharge battery before I go to bed and unplug @ 100%.
I usually get one day of battery during work inside a building with E (not H) so not so strong signal. I make ~30 min total call time with ~1 hours of web browsing, market app install, stocks, etc... I get home with ~30% left.
During the weekends, I rarely use the phone sometimes and get 2 days or more.
Currently at 1d 3hrs and still 55%.
how do you uninstall the preinstall programs? i rooted my phone.. but when i go in to manage my apps.... i can still only unintall the ones that i downloaded. the preinstalled ones still dont allow me to un install
Use Titanium, or another uninstaller from the market...
Sent from my Nexus One using XDA App
Don't uninstall system apps with titanium. Use the freeze function first. Arbitrarily uninstalling certain preinstalled apps can make your phone go wonky and titanium does not back up system apks, only data. So if you uninstall a system app, it's gone for good.

On stock you should probably be able to go a day without the phone dying, depending on usage. Good custom ROMs with SetCPU profiles can do even better.
My advice, don't fuss around with trying to figure out what can be uninstalled and what can't. It's far easier to flash a custom ROM that doesn't come with any of that crud to begin with. If you're rooted, you might as well. Just make a backup of your stock ROM in case you need to switch back to it for some reason.
If you aren't going to do that, then I agree with the above about nixing the taskiller. Get a program that lets you monitor apps on your phone. Check it after a while and see if there are any apps that are misbehaving (using more resources than they reasonably should), then you can uninstall the offending app.
Naturally, turn off wireless and GPS when not in use. You can turn of sync as well, but every now and then you should turn it on for a bit to sync your stuff with Google's servers.
I unplug my phone around 6am every weekday and usually plug it back in between 10-11pm. My daily usage consists of mostly txts, a few phone calls, web browsing and maybe a game or two.
When I plug it back in every eveing I average about 40% battery left. I leave bluetooth and gps on and have all my mail accounts sync every two hours.
Compared to my Vibrant and even my G1 that is fantastic. The last couple of days I left it unplugged overnight to use as an alarm and it lost very little of it's juice.
I have a stock (though rooted) MT4G that is about a week or so old.
I use my phone moderately, but only talk maybe 10-30 minutes on average. I use between 30-60% of my battery in a 16 hour period. Once or twice I have used 2-3 hours of talk and heavy data useage, and I don't think I went under 25% battery in 16 hours.
It sounds like something is amiss with your family member. What does your battery usage stat say?
I would guess you may have a defective battery....
I've had my MT4G for about a month, still running stock and not rooted (yet lol). I've been paying attention to battery too. Battery life seems to have decreased over the last couple of weeks. First couple of weeks I had the phone it lasted from wake-up to bedtime on a single charge. Recently, though, it is usually at 10-20% by 6pm when I get home from work. Minimal usage, a few short phone calls, some texting, regular e-mail checking, and just playing with it for an hour or so every day (customizing home screen, market browsing, web browsing etc). Used to be when I'd plug it in to charge before going to bed it would be in the 10-20% range, now it's hitting that range about 5 or 6 hours earlier. Frustrating to say the least.
Just to give you a bit of reference, when my phone was stock unrootedi would get about 12hrs on a charge. After rooting I did a few simple things and now I get between 24 and 36hrs on a charge. The things I did after root were:
1.Keep gps, bluetooth, and wifi off when not in use
2.when at home using wifi, I change the carrier mode to gsm only so the radio doesn't constantly search for cdma signals. (this eats a lot of juice).
3.keep sync off and only sync mail when I need to check it.
4 don't use feed widgets (fb, twitter, news). I use the apps for those needs.
5 keep my screen brightness at 30% unless I'm in bright sunlight. I rarely go over 60%.
6.used titanium to freeze unwanted or unused apps and widgets.
7.use setcpu to underclock when screen is off or battery is low.
8.use watchdog to monitor cpu usage of my running apps. It notifies me if an app goes over a predefined threshold.
9.I NEVER use a taskkiller.
10.I don't use live wallpapers (watchdog has confirmed that they are ALL cpu hogs)
Some of these practices you can do without root and are good habits to get into.

So after inspiron's post about the Adam battery life being pretty decent, here:
http://forum.xda-developers.com/showthread.php?t=948923
I saw some threads about how to make it better here on XDA and elsewhere.
Apparently the "Cell Standby" application takes up a decent chunk of battery life from any android tablet running it.
While I can find info about removing it on the nook color, such as the post here: http://forum.xda-developers.com/showthread.php?t=888216
I'm not sure if that'll work on the adam.
Has anyone had success in removing that process, or is any intrepid coders willing to try to find a way to remove it?
there was some information about this for the viewsonic tablet, which is closer to the adam, ill see if I can find the link to that. I'll end up messing with the adam this weekend.
There have been several posts from a luis84 over at notionaddicts.com and he indicated that he was able to shut it down using a variation of the nook script. He appears to be onto something with what he has done.
http://www.notionaddicts.com/forums/showthread.php/1437-Battery-life/page10
Here are his last couple of posts:
"adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
adb shell mv /system/app/Phone.apk /system/app/Phone.OLD
adb shell mv /system/app/TelephonyProvider.apk /system/app/TelephonyProvider.OLD
adb reboot
is the code used.
of course that did not work on my Adam so I manually navigated to the directories and renamed the target files.
Here is my results: I don't know yet. I just did it, I will post results later. After a reboot the cell standby is gone which is a good sign."
"@Flaunt after letting it standby all night it lost 3% charge. I then proceeded to watch Justin.tv (no judging) for 2 hours in Bed this morning, which is LCD at 80% brightness + Wifi for data (Justin.tv is streaming) and it lost an additional 9%. So I would confirm it is a SUBSTANTIAL IMPROVEMENT. With these results, I could theoretically watch streaming TV for 11 hours without a problem.
I am fairly impressed. I still feel it can do better, there is a ton of other crap running. I am hopeful once honeycomb comes and real support for the TEGRA 2's power management system.
I recommend everyone to immediatly remove the cell standy service. One annoying fault, mine came back after a reboot so it looks like I would have to run the above command after every reboot, since I rarely reboot Adam this is not an issue. I will try it again and see if it comes back, if it does maybe we can automate the process somehow."
Basically my understanding, if I am reading his posts correctly, is that he manually changed two files "/system/app/Phone.apk" and "/system/app/TelephonyProvider.apk" to "/system/app/Phone.OLD" and t "/system/app/TelephonyProvider.OLD" and then after a reboot, the cell standby service process was no longer running, but after a subsequent reboot, it reappeared.

You can try use RootExplorer delete these files, it should be work.
Maybe a noob question here. Would removing/renaming phone.apk also remove the 3G data connection or only voice calls, which the Adam doesn't support anyway?

The issue is that because Android up till now (pre-honeycomb) has exclusively been a phone OS - there are certain apps and processes that may be running that deal with phone features. Those apps - even if a device does not support their function - may run in the background and drain battery life. For instance, and this is hypothetical, the phone app may constantly be searching for signal or phone antenna and never find it but keep running in the background.
As of yet - no one really knows what CELL STANDBY does - however it appears that removing the app improves batt life.
i will give this a try since i dont use my tablet as a phone...{silly people} lol
i usually get a 24-29% drain through a day with minimal usage. with most of it going to cell standy...whooping ~71%!

Great Inspiron,
Can you check you still have 3G data functionality when you remove phone.apk and the other file mentioned.
I am not sure if these apps also handle part or all of the data connections (wouldn't expect them to but you never know).
Sent from my HTC Desire using XDA App
instead of seeing Cell Standby i see Phone Idle...should i be concerned? It's like consuming like 89% percentage of my battery usage after an hour.
Phone Idle - 89%
Wifi - 7%
Display - 4%
It all depends I guess... in that hour, how much did your battery go down? Going by the quoted NotionAddicts post, if they had only 3% battery loss when the adam was left on overnight, and assuming at least 6 hours, that is a total system drain of about .5% an hour. The only way to determine what your saving is to measure what battery % your losing while doing nothing with the Adam (screen off, in standby) with both the standard setup and the modified setup. I would try to do this overnight (to avoid withdrawl ) two nights in a row, keeping the time the same, and then comparing the results
If adam loses 25% after 6 hours with Cell Standby, then you can extrapolate a time of about 24 hours in standby. If the adam loses 5% after 6 hours with the Phone.apk/TelephonyProvider.apk renamed/removed, then you can extrapolate a time of about 120 hours in standby. Therefore, with those numbers, you would have 5 times the standby time with those apk's removed. (The numbers used are for illustrative purposes only)
Another thing people may want to try is removing/disabling the DRM Content service. I don't know if it would apply to the adam (as many other android phones don't have the issue), but I have a samsung epic 4g, and on the current stock rom, that is one of the biggest battery hogs because it won't let the phone sleep properly sometimes resulting in about 5-10% battery loss an hour (1500mAh battery compared to adam's 6500-7000 mAh battery (if my math is correct)). If you remove it, it may cause audio/video playback issues, but if you just disable it using Titanium Backup (by 'freezing' it) or Auto Starts (root needed for both), everything works fine.
Assuming you've enabled Market access already, you may want to make sure that everything in the market is still viewable. There were problems with the second to latest build of Nookie Froyo for the Barnes & Noble Nook Color because the dev had removed Phone and Camera APKs. Once he restored them, the apps were back for everyone.

i can't give straight numbers, but after minimal uses, my battery drain down to 72% after 10.5 hrs. i was expecting my batteries to be at like 55-64%. that's with Auto-Brightness enabled and everything else disabled. but i did connect to the internet once to check whether i got the update

On my HTC Evo with the Seidio 3500mAh battery I accidentally left it in airplane mode for 19 hours, battery loss was just under 3% also, I have not seen "cell standby" since two updates back (the one before christmas, not the one right after). Should be getting my Adam the first week of March and hope to be able to get some impressive battery life out of it. I always run my screen brightness at 12% or less indoors on my Evo, so I may spend most of my time in e-ink mode on the Adam. Since I got the wifi model, I'll be rooting and trying the afore mentioned renaming of the cell .apk's and I'm looking forward to anything else that comes up on XDA for battery improvement.
hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state) .this situation's screenshot is attached and named : Screenshot_2018_01_21_07_05_15.
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test [this situation's screenshot is attached and named : Screenshot_2018_01_21_07_49_27] )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
any help with this issue is appreciated.
.............................................................................
update 1: 1/27/2018
- flashing rom to previous stock version (v10f) was not give me any clue and it seems is not related to the problem.
- testing phone in safe mode couldn't help to decrease draining .
- turning off or on second screen doesn't solve the problem yet.
any help with this issue is appreciated.[/QUOTE]
Hi,
It's difficult to find the culprit from your screenshots. Maybe you had an app update after what it started to behave incorrectly. Maybe your google account backup or synchronization are misbehaving. There can be many different reasons for this drain.
Anyway, taking into account the actions you've done, you must be a really advanced user, so probably you should try a more advanced battery monitor application, with detailed information regarding draining. I use betterbatterystats, it helped me to find my draining culprits. Unfortunately, it's paid, but if you couldn't find the culprit by yourself from the logs, the app's xda forum will always help you. Or you can use any other detailed battery monitor, which log contains kernel, sensor, app, service, wakelock drain.

HI, this is my last night 's stats.about 8% battery drain in about 4 hours sleeping condition and the phone is in Airplane mode, by Greenify App all background apps are hibernated, second screen is off (although I set second screen to being off but morning I see it was On. I think because of scheduling daily timeout ignore setting of second screen ).
I feel that second screen when main screen is off, has a great role in draining battery.

Hi,
Well, I don't think, that your 2ND screen is the culprit. I think so, because my idle drain with 80 apps, lot of widgets, 3 different weather app, wifi-second screen-data always on, high location services, greenified almost every app excluding What'sApp-Viber-2 different mail app with push notification, so my idle is 0,7-1,0 %. Other more experienced user say, that normal drain is about 0,5-1,0%, depending on phone of course.
Unfortunately your screenshots don't contain enough information, so I can only guess. Maybe you have an SD card, which was used in Android 6.0. If yes, you should delete Android related folders from your sd card (or copy necessary data to computer, format sd card on your phone and restore your data from computer). Also a good idea to debloat your phone as much as possible (disable unnecessary apps, which were already on your phone). Quickmemo+ can possibly drain the phone, if you don't use it, maybe you could greenify it (is it possible to greenify system apps without root???). Maybe you should try to disable Google backup for awhile and see what happens. Also you can turn off Google sync you don't use.
Due to the fact, that root is no solution for you, and your phone is draining abnormally, maybe would be a good idea to factory reset it, update it via computer, and set it up as a new phone - don't restore your apps from backup, install them one by one, and see which gives you this horrible drain. If you've already done this, or don't want to waste your time with this, maybe you should visit Lg's service center, so they can find the solution.
I had some bad battery drain last week due to the app viber, took 11% in 3 hours.l,without me even opening it in weeks.
I unistalled it immediately.

Hi, thanks dear kovacszj. you kindly follow my issue.:fingers-crossed:
we have same methods in testing and solving the problem. I have considered your recommendations before. i don't have any sd card on phone and i have disabled suspicious system apps like Quickmemo+,Google apps like drive and hangout ... ,set one by one permissions of apps and take any unnecessary permissions and etc.
As I was thinking that battery drain is related to screen consuming (specially second screen), after 100% charging, over last night, attached results are obtained. as you can see 20% draining!!! Over about 8 hours sleeping condition. as you see in screen daring image ,20% attributed to off screen usage. how you explain this?
The phone was in airplane mode and all apps are greenfield using Greenify app and phone is factory reseted and all apps are updated from Google play directly.
** Second screen was On and in dark situation to decreasing screen brightness.
Another important issue is shading in main screen. by a simple search i found that many users have complained this issue too. i faced with this before but it was not so important to me because it goes away during time (may be temperature goes down).but i think we have to consider it as a sign of LCD problem if you agree ?
Unfortunately service center of LG in Iran offers very bad guaranty service and i'm not interested to waist my time with them unless any hardware replacement using guaranty situations.
In second stage I downgraded to previous stock firmware (v10f April 2017) using recommended stock KDZ files and tested it again and same results obtained. So firmware is not effective in draining of battery.Fast charging performance was good (45% charging in first 30 mins and full charging in 90 mins).

Hi,
Your very welcome, but unfortunately we still could'nt find your culprit.
For me it is kind of strange, that your trouble started with firmware update, but firmware downgrade is no cure for you. So this means, that you have a hardware problem (could be the screen or the battery or even worst the motherboard), or you still have one process or sensor running while your phone is idle (60% app drain indicates that). First of all would be great to see detailed information on 60% app drain. What information does Gsam provide on app sucker?

HI,
I did my test again with second screen was Off and same results happened. As you see in attachments in about 4 hours sleeping with fully screens Off, draining is remained. 12% draining (battery goes to 88%) exactly as it shows for off screen usage in picture. Therefore being screen on or off is not relate to draining. Unless internal motherboard current draining that I can't realize.
Now I want to restore v10g sep 2017 firmware and return to first place and go on.
One of friends recommend me to test phone with safe mode.
I either tried to root my phone to gain more stats of log files but unfortunately despite of using Santadirty instructions it not continued and I failed in step 8. I will try it again with changing my windows os.
Following you see the off screen stats.
While I was using phone I checked gsam's stats and result is amazing.
Second screen is off and main screen is on now, but it shows draining in off mode is continuing!!
Look at pictures and compare them with pervious post images. 4 hours with 12% draining for off screen and it increased to 21% while I was using phone!! :cyclops:
How off screen increased while main screen was on and second screen was off.

Your friend gave a wise advise, hopefully you could find something in safe mode. Also before changing hardware on your phone, definitely there's a reason to root it, but it is up to you. I rooted my phone according to this:
https://forum.xda-developers.com/showpost.php?p=72716640&postcount=613
In case if you have double sim variant.
I hadn't any problem with root, if you have question send me a pm.
hi again
first of all , safe mode didn't help and same draining happens.
in following you can see overnight log report representation. 24% draining !! over 8 hours without moving or using . . i'm really confused and can't find any clue why such discharging happens!
please note that
-the phone from 1:06 am to 7 am was in fully standalone condition on the table.
-after 7 am second screen because of scheduling time automatically turned on.
-after that i turned on WiFi to take log report and sending it via email and Network signal turned on too.
-as you can see there isn't any foreground app
-unfortunately discharge rate is very high between 2.3% to 5%. and averaged 3.01% /h.
-doze time is approximately normal and indicates full sleeping. according to Discharge rate figures (see attachment named this) when doze time is orange discharge rate is 0% but exactly when we are in blue dozing section discharge rate go high up to 6%/h!!!!!!!!!!.
- in Activity Manager Proc section (i highlighted in attachment named to this for 5:02 am) , there are a few system processes like:

please check yesterday charts too.
today , 20% draining in 8 hours sleeping ! again. exactly same rate as before. The more time it takes, the more battery is consumed.
beyond this report, sometimes, despite the fact that the auto brightness is active,but its action does not work by changing environment brightness! and i have to unchek and check again its checkbox via notification bar to activate this feature again.

My F800L Korean V20 also have battery drain too
Hi,
i have a F800L Korean V20 and also has battery drain too. It drains 40% overnight with WiFi, Mobile data, BT and Location all turned off. I charged it to 100% battery before going to sleep and ended up only have 60% battery in the morning after I turn the main screen on. However, if I turn on the airplane mode at night time, no battery is consumed and I get 100% in the morning. As soon as I turn the airplane off (only WiFi turn on), the battery usage is around 7 - 8 %per hour even I leave it idle. I think the battery draining issue is related highly to the radio usage by some un-identified processes/apps. I would be appreciated if anyone could point me to the right direction to this problem! Thank you!

In the idle time it is estimated not to draining exceeds 1% per one hour.so you and me have serious problem.
Please follow this istruction like me .may be we get a definite result together.

I have found the cause of the battery drain of my V20.
I simply changed my radio to G3/UMTS from LTE and the problem gone! It only drains around 1% overnight! Even I turned all data/WiFi/BT/GPS on, it consumes only 1% - 2% during the day if it left it idle.
I suspect it's due to my home is situated in a weak LTE covered location, the phone need to switch to scan / switch to different base station for connection. It might also need to switch to 3G or GSM bands for connection if the signal is too weak for connection. The process run throughout the night and consumes a lot of power!
This is definitely the culprit as I'd double checked it by switching back to LTE mode again and the drain returned !
You might try this for you V20! Good luck!

This solution seems not applicable to my issue because i have turned off network signal by ring the phone to flight mode during overnight. Unless flight mode not affect draining due to switching between opertors.! Is this ?
Hey! Just wanted to let you know there is a way to get full Gsam battery stats without root. If you Google "Gsam battery monitor without root" you'll find the instructions. All you have to do is run this ADB command:
adb -d shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS
This will allow Gsam access to full battery/power usage stats. I'm also on a unrooted H990DS with full stats. Really helps when diagnosing issues like this. Good luck!

In airplane (flight) mode, all radio (including the basic telephone voice calls) will be turned off. Your V20 should not have any battery drain overnight as a result.
If you do, you have a different cause for the battery drain!
I suggest you do a factory reset. Without installing any app, you turn on the airplane mode overnight to see if any battery drain. If you still experience battery drain, you better return it to LG for repair.
cheers.
