Try this. For one hour (not on wifi) put the screen brightness to its lowest setting. Take note of the battery level. Now use the phone A LOT. Send texts, whatsapps, browse Instagram, Facebook, Reddit, Wikipedia, Twitter, Snap, search Amazon and EBay, hit every app and website you normally use...just don't 4G stream any YouTube or HD content.

Now See how long it takes for your battery to go down even 1%. So far Its been 50 minutes on this train ride and I haven't gone down even 1% yet. I left my spare battery at home so I turned off Bluetooth, closed all the apps, and lowered the brightness all the way. I thought the battey wouldn't make it an hour. Didn't budge from 25% the whole time!

Shows you how good 7.0 nougat is now at maximizing battery life. The display battery thirst and your carriers network is another story but that's not on the OS. I always knew the display and LTE cellular signal is the main culprit but I never realized how little battery is used doing 90% of my usual tasks over 4G LTE.
[LG V20 Guides, News, & Discussion] @rbiter:
LTE doesn't drain battery for me. My bars are pegged at home and most places at work in the medical center. Wi-Fi uses more battery than LTE. At least that is how it has been since note 4 when power enveloping was introduced. Moto x is excellent on wifi too. Screen brightness is the killer. Too many rely on the awful automatic on v20. Gotta manual set it for each situation. Moto x works decent and so did notes if you remembered to lay phone flat a few seconds and it would readjust. The v20 will keep same high brightness even if you turn screen off and turn back on in another room. Need a mod so auto brightness works proper instead of pegging the brightness and staying there.
[LG V20 Guides, News, & Discussion] storm68:
Fluence uhd kicks it up a notch. Look for it in mods and apps ☺️

I no longer use those what I call task killer apps lol
[LG V20 Guides, News, & Discussion] RdT21:
I beg to disagree. Data usage consumes more battery imho vs. using wifi. Maybe you are using wifi and LTE at the same time that is why you are saying wifi consumes more. Try turning the other off and try for 1 hour which drains battery. Data connection sends packets of data all the time that is why they drain the battery more. Plus you will feel considerably more heat with data on rather than wifi connection only.

[LG V20 Guides, News, & Discussion] Aaren11:
Generally I'd agree, but I've been struck by how low the screen on drain with my 918 is. Compared to almost every other handset I've had, the difference between drain while browsing on wifi vs cellular data is almost negligible, in fact it makes me feel like the wifi modem in this phone is less efficient than most, even though I'm yet to exceed 12%/hr on either mode of connection.
[LG V20 Guides, News, & Discussion] RdT21:
I guess that is a hardware problem or inefficiency. hehe

That is the first time I heard wifi and data using almost same battery. Have oyu tried factory reset? That sometimes work. Sometimes....
[LG V20 Guides, News, & Discussion] Aaren11:
Wifi on this phone and it's predecessor is notoriously power hungry or slow. There's quite a few threads on here about it. Not only does it cause issues with the screen on, but it also seems to be responsible for a lot standby drain.

https://xdaforums.com/v20/help/wifi-issues-t3572706

https://xdaforums.com/v20/help/wi-fi-constantly-running-t3523357

https://xdaforums.com/v20/help/wifi-prevents-deep-sleep-t3535271

So it's likely more a software / hardware issue with the wifi module, rather than seemingly the world's most efficient cellular modem.

You can even see from this thread for the V10, that LG has I made some pretty dubious default settings for the wifi module so... that may be part of the problem.
[LG V20 Guides, News, & Discussion] @rbiter:
I hardly use wifi. In the last 3 years even. Since note4 introduced power envelope LTE has been consistently better drain wise. Tried many a rundown and compared phones, including iPhone. I am on T-Mobile and my signal is pegged. At&t LTE is barely usable and my iPhone has wifi always on.
[LG V20 Guides, News, & Discussion] Lgv20user:
Best battery life I've encountered on a phone. All on WiFi, couple hours on bt, YouTube videos, typical phone usage. Rooted, running Natf mega rom with Nss kernel.
[LG V20 Guides, News, & Discussion] RdT21:
I average about 6 hours SOT but usually wifi connectivity as well and less 3G data. Emails, text calls and some games.
[LG V20 Guides, News, & Discussion] herrzeba:
I have Asian unit for a week. About 4-5 hrs sot with WiFi and 50% brightness. 2nd display always on (it doesn't eat battery). I did 3 live cycles to calibrate battery. For qhd with such a small battery it's okay. I'd prefer S7 edge, but it's over 500 euro and you never know if you get crappy unit. I got this on ebay for 450e with shipping. I also disabled apps I don't use and Google backup. I love secondary display.

Things I don't like: so so front camera, sunlight brightness poor, camera slower than S7 edge and I have black haze just below 2ndary display that I only see on white background.
[LG V20 Guides, News, & Discussion] muzzab:
the battery is good. but i hope there will be manufacturer that will provide us with some kind of 4000+ mah battery without compromising the look of lg v20 which i mean, making the case for that battery that flushed together with the hump of the camera.. i think it's possible but maybe just me.. so far i found battery with 6000 and 10000+ battery with terrible and ugly cases.. someone please do it.. love
[LG V20 Guides, News, & Discussion] coolravsun:
I am getting really bad battery life with V20. At best just 2-3 hours of Screen On time. Major battery consumers are the following:

1. Android OS

2. Phone Idle

3. Cell Standby

4. Android System

In fact, overnight, battery drains by 25-30% even though the 2nd screen is scheduled OFF from 10:30 pm till 6 AM! I have tried the following to get a better battery life but no improvement:

1. Depleted battery to 0%. Charged it to FULL while switched off.

2. Turned-Off the phone, removed the battery and re-insert

3. Factory reset the phone and fresh re-install and setup everything (apps) from scratch

4. Even got the V20 replaced with another V20 after 2 weeks.

I have WiFi-ON, GPS-OFF, LTE-ON (in use for less than 4 Hours). The only apps I have installed are the usual Google Apps, WhatsApp, Facebook, Skype etc. What could be the issue here?
[LG V20 Guides, News, & Discussion] shazdirand:
Are you using the original battery that came with your phone or did you happen to buy a second battery? What is the cell service like where your phone is kept overnight?
[LG V20 Guides, News, & Discussion] trongnghia2411:
I have terrible battery life with V10f (H990DS Taiwan). back to 10e and everything is normal!
[LG V20 Guides, News, & Discussion] coolravsun:
Yeah, I am using the Original battery only. The cell service is fine. There are at least 3 bars at any point of time. Last night, I had the battery at around 9-10%. Before going to sleep, I activated "Battery Saver at 15%" on my LG V20. Today morning, the battery was still at 9%! Also, I have just installed AccuBattery to get better data to investigate what's actually happening with my phone battery.
[LG V20 Guides, News, & Discussion] Lgv20user:
If you're rooted, check out akt app and wake block app. Both do wonders for battery life on the v20
[LG V20 Guides, News, & Discussion] amirhosseinakb:
hi

my v20 phone battery draining was about 1% per hour before (about 7% totally ) (i think before updating firmware) 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.

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.

Hw long have you had the phone and was it new when you bought it
[LG V20 Guides, News, & Discussion] amirhosseinakb:
HI. About 11 months I had it. And yes it was new.
[LG V20 Guides, News, & Discussion] One Twelve:
Try with bbs

https://www.xda-developers.com/stop-wakelocks-android-without-root/

to see where the partial wakelocks are from

Do you have a pc that you can use adb with ?
[LG V20 Guides, News, & Discussion] amirhosseinakb:
HI, 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.20% draining!!! Over about 9 hours sleeping condition.

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. Many users have complained this issue too.

Unfortunately service center of LG in Iran offers very bad guaranty service:(

In second stage I downgraded to pervious stock firmware (v10f April 2017) and tested it again and same results obtained. So firmware is not effective in draining of battery.
[LG V20 Guides, News, & Discussion] One Twelve:
Try with safe mode overnight and post how much drain.
[LG V20 Guides, News, & Discussion] amirhosseinakb:
i put my phone to safe mode (factory reseted and no third party app installed and airplane mode is on and every service like wifi is off) and after 3 hours draining was 8% ! . 4% less than without safe mode but again it's more than past :( before , when phone was acting normal i had 8% with about 7 hours overnight with same situation .

any help please.
[LG V20 Guides, News, & Discussion] One Twelve:
Try what is mentioned

here

You don't have to run battery down to 10%, 80% should be enough

Send the bug reprt to your gmail and download it from there before uploading to the server

Post your screen shots here and let's see what is going on with your phone :)
[LG V20 Guides, News, & Discussion] Rhiozan:
Its been many years since my last visit to this forum. It feels almost as if I'm home again :D

Anyway, I have a similar issue with my LG V20. I bought it this summer. It was brand new unlocked AT&T device. The battery life was very nice so far, I could go through the day without charging it. Without disabling wifi/data during the night the phone could use less than 5% of the battery which was very pleasing. I could wake up in the morning, do my routine with playing vids on youtube and then arrive to work with around ~10% of my battery spent since waking up.

Now I know the batteries degrade over time, but the changes that happened are SUDDEN. Just a couple of weeks ago my phone has started to drain battery like crazy. It can lose like 30% overnight. And I can lose almost half the battery before I get to work! This is rather insane.

I am very careful with the apps I'm using, I disable push notifications pretty much everywhere except messengers and I haven't installed any apps recently.

The phone feels slightly warm, which means that some processing is going on. If I disable all connectivity (like before going to sleep) then I find again that phone uses less than 5% of the battery overnight.

I've used Accubattery and System Panel 2 to try and find the culprit. The System Panel 2 shows I have lots of "unaccounted" processing. Any Idea what this might be? System info and screenshots are attached. Thank you!
[LG V20 Guides, News, & Discussion] One Twelve:
Try restarting the phone. Once i noticed this kind of drop when i woke up. A restart seems to have fixed it. How often do you restart your phone ?

Battery degrades 20% after ~500 cycles. So battery should be 80% what it was when new a year and a half later. This will manifest itself with a proportionately lower run time

Don't have to disable all connectivity. You could try just disabling wifi when screen is off from Advanced Wifi in the wifi setting

Phone feeling warm is a clue its working, question is what is it doing. A warmer battery will always drain faster. Can you mention in degrees C, how warm it gets

What does it say under wakelocks ? can you screenshot that

An off screen drain of 6%/h is high. Something is going on. For how long were you streaming audio as a percentage of the battery cycle
[LG V20 Guides, News, & Discussion] amirhosseinakb:
here is the result from 10 am to 15:20 pm with about 13% draining in 5 hours! . this test will be repeated this night to gain overnight precise standalone draining and i'll put its result tomorrow morning.

-both wifi and Mobile signal strength is normal and great.

-just 2 background apps are working that both of them are battery monitoring apps.i uninstalled one and installed another one in middle of time.

- from 10:05 and to 12:30 i didn't do anything except checking battery .

-between 12:30 to 12:48 i started using wifi and installing 2 apps from google play that makes 3% draining.

-in 12:51 i exit airplane mode and signal in started.

-after that until 15:20 i didn't do any thing .

-because of changing brightness of room sometimes second screen brightness change automatically.

-after about 1:0pm about every 16 min we see 1% draining .

any analyze will be appreciated.
[LG V20 Guides, News, & Discussion] JUN10R831:
Im getting roughly 30% to 40% drain over night when the phone is on standby. In the mornings if my phone starts off at 100% by 9 oclock its down to 15% and i get up work at 6 so thats 85% of the battery gone with little to no usage. I havent rooted my phone so any apps ive tried to download so i can see what the problem is dont help at all im still at the J update so its still rootable might do it today see if i could figure out what the problem is if i cant proably just get another phone cause this is a annoying issue to have with a phine thats less than 4 months.
[LG V20 Guides, News, & Discussion] Rhiozan:
Thank you for the reply!

Some time ago I restarted it very rarely (like once in a month. There was no reason to, really. Restarting it doesn't resolve the sudden and intense battery drain

I'd disagree here. The Li-ion battery life is around 400 cycles in total. I'm not sure about the smartphone batteries in particular, however you can look at the specs for Samsung SDI or LG Chem 18650 cells and most of them normally have around ~400 charge/discharge cycles. The smartphone battery will degrade by 30-50% over the course of a year with typical use. This what smartphone manufacturers will not tell you. And the trend (and de-facto the standard) of using non-removable batteries is very annoying.

Will try that, thank you!

I've been monitoring it and the AccuBattery shows the temp to be around 22 (+/- 1) degrees Celsius most of the time.

Sure, the screens are attached.

I have Mixcloud (which is the only streaming app that I use), but I barely use it.

Should I proceed with these recommendation? https://www.xda-developers.com/stop-wakelocks-android-without-root/
[LG V20 Guides, News, & Discussion] One Twelve:
Can you screenshot , tables - History stats - foreground process summary (select)

The reason is if you look at doze line in the graph its mostly orange instead of blue, very little blue so its not sleeping properly and maybe that is because foreground process is a solid blue line.

Some app is running non stop in the foreground, see foreground process line in the graph is a solid line during this period

This is where i expect to see a line in foreground process but there is a gap in the line. This is the only time there should be a line under foreground process in the graph as you are actively using the phone in this period

Second screen drains 1% per hour. So off screen drain is 2.6% - 1 = 1.6%/hr

Since you have second screen on when main screen off, good off screen drain rate should be little over 1%/h instead of 2.6%/h

Takes about half hour to go to blue doze but it never reaches there. is phone resting on a table or in your pocket. If motion is detected phone will not enter deep sleep

Again we see foreground process line in the graph is a solid line during this period

I do not see any solid cpu lines when phone is not being used which is good, there are only the regular lines
[LG V20 Guides, News, & Discussion] amirhosseinakb:
hi again

thanks for previous analyses

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. accordig 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:

[LG V20 Guides, News, & Discussion] One Twelve:
ok, when i see that first graph i don't see any problems, user space and cpu have notches and no solid lines anywhere. No rogue process is running. But battery is draining

Second graph with screen off discharge rate/h you see the rate is jumping, it should be a straight line ideally or not shift too much. And it is happening when you have a solid blue doze line from 2:30 - 8:30. The phone should be in deep sleep and not doing anything. So something is happening and this tool isn't telling us where the problem is so have to try something else

Before doing that, turn off google location history if you have not done so already

- settings - google services - location - location services - google location history (if it is greyed out, turn on gps)- Now click google location history and see (is it on or off?) switch it off - then turn gps off

Do another test for 8 h and lets see how much drain you get

Next step, is we have to try anther tool and this requires you to have adb. For this you need a PC. Is this possible ?

---------- Post added at 06:42 PM ---------- Previous post was at 06:33 PM ----------

See post #222, whether you can install BBS and then do the adb setting
[LG V20 Guides, News, & Discussion] amirhosseinakb:
hi and thanks for your instruction .

about google location history i disabled it before these steps as you can see in attachment i paused it from google accounts website and my phone either.

Also all permissions to google services is deactivated.

Greenify app force full doze in adition of system dozing immediately after screen off.

i'm familiar with adb environment and my pc is configured for any adb actions. LGE driver is installed , adb and fastboot is installed.

i'm ready for any more instructions.;)
[LG V20 Guides, News, & Discussion] One Twelve:
yes, but can you confirm it is off on the phone ?

enable gps, then click on location history and check if it is off or on. Set it off, Then turn of gps

Do you think Greenify is helping ? i'm concerned whether it is skewing the results. Whether we can test full stock without greenify

Are there any other battery apps you have running ? whether they are interfering with each other and this is why the results make no sense

When there are no apps greenify should not be required. The phone should enter deep sleep after 30 mins on its own if it is left stationary

Good i just want the ground work to be ready before you use BBS
[LG V20 Guides, News, & Discussion] amirhosseinakb:
the service of google location history not available in Iran. when i click on "google location history" after turning on location setting , it says that this service is not available in iran. but i disabled it from website in my private google account that i set it in my phone.

i don't have any battery management app now and about Greenify app i have to say that previous results accrues while presence of Greenify app. but if you consist on uninstalling it i will do it before tonight test.

but if i uninstall greenify what is the best way to stop running apps in background? (without depending on android system standalone condition dozing) . i just know only "Battery and power saving -> battery usage -> battery use details " section .

another setting that i find now is in the "Developer Option -> Background process limit" that i'd like to set it to "No background processes" , if you agree?
