Battery draining help needed!!!

I have check out by battery is in good condition.
but still i have battery drain problems.
problems started the day one i flashed a rom.
and the battery draining problem is just due to display.
without display on data connection on, and full time in proper connectivity area:
with music playback i get approx. 10hrs
or with bluetooth 6hrs
or on call i got 5 hrs
this were my battery stats.
but with display on for just 1 hr without any use idealy on homescreen itself it.
so i needed to know were will i get to change the display settings as i was using the lowest brightness of the rom.
i needed to change other features of display were are they available.
it will thankful of you if you help.

Turn your contrast down, use a conservative kernel setting and apart from that, if its still really bad (after a few battery cycles) then its f+$%ked unfortunately.

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 )

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).
testing battery drain in safe mode in done and didn't change results
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.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the LG V30's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

I've noticed that the standby uses up quite a bit of battery compared to others i've used. Its right up there with my SOT percentage wise. Still has plenty of battery left though so not a huge concern. I also have the Always on Display turned off to help it along as well.

I noticed that standby drain is increasing when you choose 4g mode but the coverage is not good, or when you are on the move it keeps switching between 4g radio and 3g radio and that drains a lot. If you don't need 4g or the coverage is hit and miss you can just switch to 3g for better battery. I get around 20 mbps with 3g and it is mostly ok.

No drain. Battery life is incredible. If you have drain, I suggest you install Wakelock Detector Lite and find the app responsible.

Disable Volte. Problem solved

LG V30 US998 ( Converted from H931)
HI,
So I converted to US998 from a stock ATT H931 using ChazzMatt process from another thread. The reason I went this way was because I could not use wifi calling on my new carrier, T-Mobile. After a fair amount of difficulty getting LGUP to behave, I now have an incredible phone.
After 48 hours off the charger, I still show 79% battery remaining. Now, I do not make or receive a lot of calls and I am not on the phone all day as I have a regular job. I also don't know if there is a battery calibration issue here. All I can say it lasts way way longer than it did with all of the AT&T bloatware installed.
Gie it a rip. I think you will find the same results.

Battery life is very good on this phone both standby and SOT. But there is a catch. There is a huge problem with doze mode and notifications not comming in time. This actually is a very common problem with all manufacturers. As I have two apps that recieve alarm notifications both from work and home systems, it is crusial for me to get this notifications on time. As it turns out this is mission impossible. I don't know if the problem is in the apps or the os, may be both. So I had to completely disable doze mode from adb with this command - adb shell dumpsys deviceidle disable
The problem is that it survives till next reboot on non rooted phones but it is still something and solves the problem. But it increases slightly standby drain.

You can exempt any apps your wish from the LG battery optimization. It's in the interface. You don't need ADB.
Go into Settings and search for Power Savings Exclusions.

Tried that first. Not working properly. Sometimes was ok sometimes I was getting notifications when I unlocked the phone.

45 hrs on standby

US998. No drain. The key to this is simple. I have my phone set to turn off Always on display from 10pm to 6am. It's too bright at night and causing the phone to lose battery needlessly for 8 hours.

Why is your phone screen on during those hours unless you're using it?

Inconsistent battery drain overnight

I've recently bought the LG G6 and while many things works very nicely to me and overall it feels like a solid device I still have problems regarding battery drain overnight. Besides a relatively high drain I also noticed it to be very inconsistent draining from 3-4% to 10%-16 in periods of 8-10 hours under about the very same conditions. I've tried to track down the causes using multiple methods so I have a lot of bugreports going thru Google's Battery Historian tool and dumpfiles from Better Battery Stats app. I can post them if it helps but so far they didn't helped much to understand the reasons for the drain and the inconsistency as well. I though it was coming from a weak WiFi signal or poor mobile signal but it's not related. My settings are: WiFi always on, Sync on, AOD off, data on, Do Not Disturb on overnight, VoLTE is always off, Location turned on (high accuracy + iZat on but wifi and BT verification off) etc. Suggestions are welcome.

Do people not leave phone on charge overnight anymore?

I used to but I don't think it's the best practice. Probably will have an impact on battery lifespan and since we have quick charge is also unnecessary I guess. Also, losing less battery while stand by provides more SOT.

It will 'cut off' once fully charged. Doesn't cause any real issues. Unless you keep the phone for 4-5 years.

Yeah but I'd still want to improve stand by drain to have a better performance during the day.

I can confirm an issue with very high overnight drain. I turn off all radios and typically use the app switcher to close all running apps. Despite this, on a couple of occasions I woke and found that battery had lost about 25% overnight. Looking at the battery drain history it was clear that the phone had entered a very low power doze state, stayed there for a few hours and then often around 3AM would kick into some kind of high power usage state wherein the battery tanked. I don't know what the cause is, but it's not something I like to see. I often use phones on backpacking trips where there's no ability to charge and managing charge is important. With reliable doze, there's no need to turn the phone off, but with this behaviour, it would be critical.

That's really worse than what I'm reporting. My device still goes into full doze after a while on light doze. My drain is significant but never over 16%. I'd suggest you to run Better Battery Stats and look for wakelocks.

How much battery does AOD drain?

Hi everyone!
In my case, AOD drains 3.2-3.6% battery per hour, and I was curious if the consumption can be lower.
How much battery does AOD drain for others, especially on stock OOS?
I'm currently using Evolution X. For the sake of experiment, I keep my system clean (pretty much no apps besides the pre-installed ones) and measure consumption overnight - just keep my phone still for 9 hours. With AOD off, the battery consumption is only 0.2% per hour. I tried turning on Airplane Mode and Idle Manager, and flashing different kernels, but the battery drain stays same.

That seems very high. Any cloud or other apps running in the background?

Nope, and the phone actually stays in deep sleep for most of time. The battery drain is related to Always-On Display.

I don't know what's normal for that phone.
The stats you're showing if on my N10+'s indicate what I said. Typically always on AOD uses >1%@hr on my devices and even better with tap on.
Maybe the firmware it's self... or maybe it got corrupted. SEUs are rare but do happen. Clear caches and/or data if possible.
If you have a tap on AOD option, try that.
