H990DS massive lag and Android OS battery drain - LG V20 Questions & Answers

Hi everyone.
I bought my V20 in July of this year and in the last week I have started to get big battery drain. Usually it's Android OS and Phone idle up the top of the list.
After unplugging it, the phone will be at 100% battery6 sometimes an hour with light use (eg browsing reddit or general Web search) then its a fast decline in battery life. I can usually tell it's happening because the phone gets hot in my pocket.
It's unrooted btw.

Android OS

I find that if i turn off location services and location scanning for wifi and bluetooth scanning and not use auto brightness and use comfort view i get a full day of battery.

Try Off auto sync, nfc, gps etc

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.

Really Bad Battery Life, S7 Edge Exynos Single

No Bluetooth, No Location - Yes WiFi, LTE 100% signal coverage, no downtime, overall low brightness around 25-40% I can't seem to get past a day of regular use with 2 hours and half average screen time. Using latest OTA.
I've turned off the always-on screen, several bloatware that came preinstalled, including Facebook and Whatsapp.
The first on the battery usage is always Android System followed by Cell Standby then Android OS (again???) and then Screen. Also the voice call seems to use some great amount of battery. Naming might be different since my Android is in another language.
Have turned on energy saving for most apps that runs on background. Doesn't help much since I don't have many apps that runs on background. Imagine if I did! My day ends with about 20~27% battery left, I just turned off fast charging to see if it helps anything. My Xperia Z3 with Whatsapp and a great deal of apps installed would end the day with over 50~65% with Stamina Mode. I know the screen is smaller but so is the battery.
So I thought it would get better with time but it didn't, it's the S7 Edge Exynos Single SIM, unbranded with the official Samsung rom so I could get the latest updates or I would be stuck with no updates at all since Frebuary, since my carrier usually only releases major OTAs such Android N and skips all the minor updates.
Yes I did a factory reset already hoping for the better, maybe I got a defective Galaxy S7? I'd hate to have my phone fixed and the battery changed, it wont be the same again unless they give me a new one which is unlikely.
Why is Android System and Android OS draining so much battery? Are there any tools to debug this and trace which processes are using CPU time? Or could this be due a faulty battery?
Settings, Applications, Google. Disable all the services that will cause wakelocks such as all security options. This is something 99% of folks overlook or forget. Post a screenshot of your battery stats
http://forum.xda-developers.com/showthread.php?t=1827676
Only settings marked above are "Allow remote lock and erase"
Here is an average day with:
**Few moments connected to my laptop transferring pictures from yesterday - so incidentally it took some charge on the way.
1 hour 29 minutes voice call, 3G/LTE signal is excelent, VoLTE not used, WiFi on occasionaly, Location off, Bluetooth off.
1 hour 12 minutes running Fallout Shelter with power saving on, 30 fps low resolution mode, that's the CPU time at least.
2hour 28 minutes screen time with very dim brightness​
Power saving ON all apps where available, I have absolutely nothing installed but a couple of games, Teamviewer and Microsoft Remote Desktop.
That left me with 49% battery. Not sure how great the results are considering the brightness was very low.
Since the image took the whole page, here are the links instead lol.

Dont quote me on this but I believe the Android System drain issue is a byproduct of the latest Samsung firmware update...
Someone more in the know could correct me or elaborate more

Just some heads up, in offline mode my phone went a full day with a 6% drop, half hour screen time and some minor gaming, when I turned the phone radio back on around 20:00 when it was 10:00AM it was down to 15% battery, solely on standby. No bluetooth No location - Yes Wireless Yes LTE

Try This If You're Having Battery Drain/Slow Mobile Network Issues

Was having trouble with both issues, pulled battery with phone on, waited a minute, put battery back in, both problems fixed!
isnt this bad for the phone? Im having horrible battery life so I'll try anything but just wanna make sure

You wouldn't want do it if on a regular basis but you can try turning phone off, pulling battery out, putting it back in after a minute and if that doesn't work, try my method.
I would wait until the battery is super low and then reset network settings under the reset menu. Power down, pull battery and sim wait 30 sec to a minute and replace everything. Then plug in the phone first and then reboot. Let it charge completely and for about 20 minutes more after it reaches 100. If you do a lot of rebooting I have found the phone has issues. I only reboot with the phone plugged in, otherwise it drops 2% every reboot..
Be careful, I did that with a ZTE Zmax 2 once (75% charged battery) and it sent a phone into a bootloop. The only means of fixing it was that I luckily had a 2nd Zmax2 laying around and used its battery on the bootlooped phone which remedied the problem. Both batteries work fine , I just swapped them between the two phones.

I used to worry about this too. This is my first LG product and it MAY be different but at the Sprint store the first thing they would normally do is pull the nattery to look at the ESN. They never bothered to power it doen forst so I asked a couple times and was told it will mot hurt anything. I had Samsung products for uears and have done battery pulls at all levels of charge and for many reasons, but I never had a problem as long as the battery had enough juice left to boot the phone. If not I had to charge it, LoL.
Just thought I would share, I personally wouldn't worry.
I know on my old Nexus 6 pulling the battery with phone on was only an issue with fsync disabled using a custom kernel. I think most phones have built in protection to stop this from damaging the file system.
so a battery pull is your fix? lol some ppl should be hard resetting every so often regardlessi reboot at least once a day

While I don't get extremely bad battery drain. The few times I've noticed it going down a bit faster than normal have had Android system at the top of the list or at least 2nd in place. A reboot usually fixes it for a while. This has happened in every ROM I've tried. Also I swear that stupid Wi-Fi scanning when WiFi is off option in locations settings turns itself on when it feels like it. I rarely turn my location on and I've checked a few times and that feature is on for whatever reason
Power down.
Pull battery.
Hold power button for one minute to discharge any juice that may be on the motherboard.
Let phone sit for 30 minutes.
Put battery back in.
Power up.
The motherboard and battery should now be re-calibrated. If you still have problems, try a new battery.

LG V20 Overnight Drain

Hello,
So I've had the V20 since it first came out and I'm loving it. With the stock battery, I'd charge it every night and not notice many issues. Noticed a respectable 3-4 hours of SOT, which is decent but not spectacular. Then i got the Zerolemon 10,000mAh extended battery for it and I still feel like the phone doesn't have the battery life it should. With the extended battery in, I would sometimes leave it unplugged overnight and lose 15-18% (which, in a 3x battery, correlates to almost 50% of a stock battery) in just one night. So i'm wondering, any apps/servies that just guzzle battery overnight? Any info is a help, thanks!
Good possibility that the new battery you have may be junk.
But you'll have to pop the stock battery in and do battery usage comparisons between the two.
Have you calibrated the Zero Lemon battery? Run it all the way down until it turns off the phone. Pull the battery and then put it back in turn the phone back on to make sure the battery is drained all the way.
Then recharge it without disturbing it. Recommend doing this overnight.
Also make sure you aren't switching batteries once you've got the lemon calibrated otherwise your battery gauge won't read accurately.

Yeah i might have to, i've been trying to avoid that. I honestly think that it's the phone not the battery, because when i leave it alone overnight it loses like 12-16%. Losing that even off a stock battery is ridiculous so i figured it was something with the phone that caused it to run all night without dozing. i read up on some threads about wakelocks after installing GSam and seeing that the phone is held awake quite a lot (as i type this, i'm sitting on 72%, 13h16m of usage, 3h5m SOT, and 4h28m held awake. So i honestly think it's the phone, but then again if i do drain it down then do a battery pull and it jumps up to 30-40%, then i'll know it was the battery
Also, would you recommend once the phone shuts off plugging it in and leaving it off, or turning it back on once i plug it in?

Don't think its the battery, it's highly likely the ROM you're using. I had terrible life after the last update.

I'm running bone stock on everything, no root
Update: been getting significantly better battery life after doing two things:
1. Turned off Bluetooth location scanning (I already had WiFi scanning turned off).
2. Using my phone without WiFi on (on the chance that it might be the WiFi causing wakelocks, which is something I researched a bit with the help of GSam. Wifioffdelayifnotused was the suspected culprit).
I'm not sure which one could be the bigger factor, but I'm going to leave my phone unplugged overnight with WiFi off, then after tomorrow night when i charge it fully again I'm going to see how much battery life I get with WiFi on (this way I should be able to determine if it was the Bluetooth scanning, or the WiFi.)
Any input would be appreciated. Thanks!
Had a zerolemon on my Galaxy S4 and while it was a great battery that added a lot of additional life, I never felt I got enough extra life that corresponded to the amount of mAh that the zerolemon brought. Though it wasn't anything like what you are describing. Just never felt like I got 3x the battery life even though it was like 3x the mAh amount but maybe that's just because I don't understand the whole science behind the mAh ratings on batteries.
Update part 2: turning off the Bluetooth scanning and Wifi (only yesterday, had wifi on today) has resulted in much better battery life so far. Oddly enough, early on it seemed a lot better, on pace for almost 15 hours SOT. I'm at 18% now and almost at 10, but still pretty good and better than what I was getting. I'm chalking it up to the Bluetooth scanning since I use an Android wear watch that I leave always connected. I'll do another full drain tomorrow after charging it tonight, this time leaving wifi on to see how much of a difference the Bluetooth scanning makes (3rd pic is early on when I was on pace for 15h SOT; left phone unplugged last night and stayed at 64% all night. So my 12-18% overnight drain (40-ish% on stock battery) problem is cured )

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.

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.

Thanks for your attention.
I have betterbatterystat app but as I didn't have intention to root my phone, I can't use its reports.
Any new idea will be appreciated.

Could you please post GSam's app usage drain screenshot. It was 60% on your first screenshot.
Unfortunately, I haven't used other battery monitor for unrooted device, that's way I have no idea which one is the most reliable.

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,
Your very welcome, but unfortunately we still could'nt find your culprit.

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:

Any help will be appreciated.
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.

battery life after last factory reset

Hello, when I bought the phone from the seller, the battery was good, about 2 months old. I downloaded another one, I do not remember what the region was before, and what baseband was and build number. So I installed xeu region software. I'm using the firmware for about 2 weeks, everything is fine, but now it's obvious that there is a problem with the battery life. before rebuilding the data, dropped overnight by 1 or 2 percent since I locked it, like 12h lock, after 9h not using one percent or two down but not 10. Wifi is off, the location is on (high-level mode) and increase the accuracy when wifi is off and bluetooth is off, scan automatically, as I turned on this feature in place to increase the accuracy of the location. with battery saving mode i want explain for understand humans turned in location settings wifi scanning while wifi is off and bluetooth scan when bluetooth is off too in location settings. and battery saver turned on in settings backround data and wifi while screen off when battery saver is enable. and from wifi settings while screen off turned off wifi. after these settings battery dropped down 10percent after 3hours. i full charged yesterday i unplug and non used two or 2:30 hours battery dropped from 100 to 99 thats normal. but how gonna did that? 71 ,to 60 per 3 hours???? phone is locked and no background app, location is on but dont remember or i ticket in settings location wifi and bluetooth scanning while off........ before last factory reset without battery saver mode dropped 1 or 3 percent per 8 hours of non-use .. I remembered that I turned on backround data and wifi when turn on battery saver in battery saving settings. all background apps are off. wifi off when the screen is off I changed from always to never which exteneded more battery saver. The battery has dropped down 10% over 3hours. before last factory reset without battery saver the battery dropped overnight by only 1-2 percent. i dont remember when i switch I turn location on or not . and wifi and bluetooth scanned is on when wifi is off.
after last reset from 71 to 60 battery dropped down after three hours with wifi is off when screen is off , location mode is on high level, and i cant remember was on ticket when wifi and bluetooth even is off, i mean never turned bluetooth on when i go to sleep and from battery saver mode ticket backround data and wifi to on when battery mode is on..
