I'm having major android system battery drain. It has been sitting at the same usage percentage as my screen. I can't get 2 hrs of screen time.. I factory reset the phone and set it up new. Thinking it might be my bluetooth causing it. Anyone else use bluetooth and having similar issues?
[LG V20 Guides, News, & Discussion] koppee1:
Philippines v20 here. Barely got 3 hrs sot. First day with the v20. Hopefully it gets better. If it still sucks tomorrow, I'm installing Greenify.
[LG V20 Guides, News, & Discussion] ccjr1116:
V20 Battery is amazing compared to the v10, this thing will go all day while the v10 went half day and needed charge. Happy camper here and not looking for extra batteries! Yay
[LG V20 Guides, News, & Discussion] jay-red:
I am not having the best battery life at the moment, on my 2nd full day and by 5pm I had the 15% warning and only had 3 hours of SOT. The past 2 days has basically been the same battery life as my v10 which I was just used to charging as soon as I got home from work.

I'm hoping it will get better after a few charge cycles, looking at my usage the Android system is the biggest culprit.
[LG V20 Guides, News, & Discussion] Swizzle82:
Exact same here. I've veen workig diligently to track it down. I'll let you know what I find out..

---------- Post added at 08:26 AM ---------- Previous post was at 08:19 AM ----------

What was your set-up process? Did you copy data from your V10?
[LG V20 Guides, News, & Discussion] @rbiter:
No less than 5.5h sot here. Except the day I used a lot of GPS and speed tests and auto brightness I got 5h sot.
[LG V20 Guides, News, & Discussion] jay-red:
Nope it was a fresh setup and I manually downloaded the apps I wanted. I disabled /deleted as much bloat that I could also.
[LG V20 Guides, News, & Discussion] Swizzle82:
Okay I think we need to see what apps we have, what some of our settings are, and other comparisons.. Do you use Bluetooth? What are your advanced wifi settings? Etc..
[LG V20 Guides, News, & Discussion] jay-red:
So today I am getting the worst battery life so far! I only have 34 mins of SOT at the moment and am down to 55% with an estimated time remaining only 4 hours. I have no clue what the deal is, I have it basically setup the same way as my V10 and that at least got me till the end of the day.

Once again my biggest culprit is Android System, I am almost wondering if something is not allowing the phone to go into deep sleep. Opening the Android System shows that it contains a ton of different apps/processes, but I dont know what one is using up the battery.
[LG V20 Guides, News, & Discussion] Swizzle82:
Are you using the smaller display setting? I've narrowed mine down to two things causing android system. One is my amazon flex app the other and mainly is second screen. Go to all apps/show system apps/second screen settings/battery then compare it to what the battery info says on android system. Look at the mah of both apps and up time and see if they're very similar.
[LG V20 Guides, News, & Discussion] jay-red:
The second screen setting shows the same percent used as all the other items bundled into the "Android System"

Some of my settings:

Never use Wifi so thats off

Bluetooth is normally on all the time since I use it in my car (last 3 phones were always on also)

Screen brightness always 40% or less

Location is normally just left on, I turned it off just now hoping to make it through the day.

Was using the finger print scanner, but turned it off for now to see if that had anything to do with it

EDIT: I also just updated the Home launcher like a previous person stated

Hope I can get this sorted out soon, this phone has had the worst battery life of any phone I have ever had! And I only have the 1 USB-C cable that came with the phone, so I cannot charge on the go yet.
[LG V20 Guides, News, & Discussion] Swizzle82:
Can you please try something for me? With the display size set to the lowest dpi. Go to an app that uses auto rotate. Scroll your second screen to your app shortcuts page. Turn the phone to landscape and then rearrange your icons. I need to know if they get smaller..
[LG V20 Guides, News, & Discussion] jay-red:
Yep, they shrink a little bit once you move them around.
[LG V20 Guides, News, & Discussion] Swizzle82:
After you reboot they'll go back to normal. I had reset my phone the other night and set it back up. I got 5 hours screen time yesterday. Best I've gotten on an Lg ever. I downloaded some bs app that crashed my phone and had to reset again. Woke up today and battery issue was back. I'm thinking this might be a second screen bug causing a display glitch in the second screen causing Android system to stay awake when they aren't shrunk like they're supposed to without rearranging. Try turning off that part of second screen or just arrange them til they're all shrunk and see if your battery life improves. I'm gonna do the same.
[LG V20 Guides, News, & Discussion] Anarchaotic:
So far averaging around 4:30H SOT. To be fair that includes heavy network-only browsing, GPS, some Netflix and taking pictures. If I limited phone use I'm sure i could get the number up.
[LG V20 Guides, News, & Discussion] chavist:
Does anyone have specific settings or apps that were disabled to improve battery life
[LG V20 Guides, News, & Discussion] twistedvip:
I know disabling facebook tends to lead to more phone stability and better battery life. It did for my phone - but mine is also stock - no root nor unlocked bootloader.
[LG V20 Guides, News, & Discussion] @rbiter:
Best yet. Been getting 6h+ SOT easy except the hardest of days.
[LG V20 Guides, News, & Discussion] cbizz:
Anyone factory reset their phone when they first get it? I don't think i'm getting the battery life I should be getting
[LG V20 Guides, News, & Discussion] klsmalls1:
What theme are you using to get the dark Background?
[LG V20 Guides, News, & Discussion] jay-red:
OK so I am getting better battery today, currently at 45% with a little over 2 hours of SOT. it's not the best, but an improvement. I let my battery completely die last night and fully charged, hoping to calibrate it. Also in my usage, android system is no longer the top culprit in drainage, it's phone idle...
[LG V20 Guides, News, & Discussion] gotti109:
I guess wait a day or two and your battery will continue to improve....

Me... I usually get 5hrs+ sot.... With 20hrs+ battery usage...

Heavy use with playing real racer 3 and watching youtube all day.

---------- Post added at 08:36 PM ---------- Previous post was at 08:34 PM ----------
[LG V20 Guides, News, & Discussion] @rbiter:
There is no calibrating it. You use your phone e more at first setting it up, tweaking, honeymoon period wearing off, tweaking a little more, tweaking a lot more if you have root, then you're into a daily routine. That's the calibration.
[LG V20 Guides, News, & Discussion] chavist:
Not good
[LG V20 Guides, News, & Discussion] HwaA18:
No, there are legitimate ways to calibrate your battery: letting it fully discharge, then fully recharging it again.
[LG V20 Guides, News, & Discussion] howdyace:
That is legit terrible.

If that doesn't improve drastically then reset the phone.

If you're dead set against that, swap it out. That's bullocks.
[LG V20 Guides, News, & Discussion] nerys71:
I am getting lackluster battery performance at best. not unusable but no where near as good as my note 4.

and I lose a TON overnight. SO I am guessing one of my apps must be keeping things from dozing off. gonna have to work on that.
[LG V20 Guides, News, & Discussion] LuigiBull23:
Best SOT yet!! ??
[LG V20 Guides, News, & Discussion] johner13:
Almost 7 hours... Not sure what happened today but I usually get + or - 5hr of SOT. This reminds me of my late Note 7. Rooted running greenify and forcedoze which I had before root. Only thing I changed was freezing all the bloat.
[LG V20 Guides, News, & Discussion] Jimlo:
I like the removable battery design on LG V20, I think it is a much underestimated phone.
[LG V20 Guides, News, & Discussion] Corbitt74:
My first 4 days or so it was just OK. But now 2weeks in its great. So I'm happy so far

---------- Post added at 03:23 PM ---------- Previous post was at 03:23 PM ----------

I agree
[LG V20 Guides, News, & Discussion] @rbiter:
Enjoy that decreased lifespan of battery. I only let my battery fully discharge once. Not to calibrate, but see how accurate the battery percentage is. From there on out, I try not to go below 20%.
[LG V20 Guides, News, & Discussion] bishmaster5000:
That's crazy, this V20 has the best overnight battery performance I've ever seen. It literally dropped from 100% to 99% over a 9 hour period. Now if I use the phone heavily it seems to die quicker than my Note 7 or Note 4 do, but the idle battery performance is stellar. I love charging the phone right before bed and it's still full when I wake up.
[LG V20 Guides, News, & Discussion] chavist:
I'm wondering how many people are actually using an app like forcedoze to control battery life. It was my understanding that Nougat was supposed to be able to do this like the battery optimization in Samsung phones. The T-mobile version doesn't seem to come with a ton of bloat wear so I'm a little concerned with why my battery life sucks so bad
[LG V20 Guides, News, & Discussion] Dark Jedi:
My first day it drained fast. After the second day battery life improved. When the screen is off it hardly uses any power
[LG V20 Guides, News, & Discussion] @rbiter:
One more before I drop on charger.
[LG V20 Guides, News, & Discussion] Swizzle82:
I couldn't get force doze to take my nonroot commands. Says it's incompatible with N atm.
[LG V20 Guides, News, & Discussion] chavist:
Does anyone with great battery life keep 2nd screen on always?
[LG V20 Guides, News, & Discussion] dbornack:
I keep going back and forth on using the 2nd screen when main screen is off. Obviously if you keep it off you get better battery life, but finding the balance of the 2nd screen being worth it or not. I've discovered that it shuts off when the proximity sensor is covered (in pocket, face-down, etc.)... so I'm trying it out with the screen on, but am trying to keep it facedown and relying on the notification sound to let me know if I have anything to check, or periodically picking it up to look. Not ideal, but.. I'm trying.

I miss my Droid Turbo in that it would stay dark until I waved my hand over it, and then I could see the time, any alerts, etc. and then it would shut off again. I'm hoping if and when Verizon root happens, we can set something up like that.
[LG V20 Guides, News, & Discussion] gotti109:
Yeah I keep 2nd screen on an always get 5+ sot
[LG V20 Guides, News, & Discussion] spexwood:
Today at work, I began to feel my phone getting warm in my pocket and pulled it out to discover that it was eating battery up like crazy! Battery went from 100% to 75% in under 4 hours. This phone hasn't been giving me great battery life since the day I got it and its really irritating. Most of the time, it's just in my pocket with sync and WiFi off, no calls, no nothing except for my Moto 360 being connected.

My main battery eaters are Android OS and every now and then, Google Play Services (most likely because of my watch) and Phone Idle. Android OS has been bad last few days though!

(Btw, Google Now cards are off, so that's not the cause for Google Play Services).
[LG V20 Guides, News, & Discussion] KOLIOSIS:
It may help to turn off a few items with GOOGLE (& others) :

SETTINGS > FINGERPRINTS & SECURITY > ADVANCED SETTINGS > USAGE ACCESS >Turn off any apps listed there if you do not want to grant permission. I see no reason to grant access to any app,YMMV,but,denying such doesn't seem to negatively affect usage.

SETTINGS > PERSONAL > GOOGLE SERVICES > SECURITY > Turn off Scan Device for Security Threats.
[LG V20 Guides, News, & Discussion] porscheoscar:
Honestly I have not checked until seeing this thread because I have been so fixated with using Quick Charge 3.0 and 2.0 power bank and car chargers. It's so much faster than what the competition are offering including the Pixel. Still I don't like using just one battery. It makes carrying the power bank a must, I would much carry two very thin V20 batteries in my shirt pocket.

But compared to my Verizon V10 the battery seems to be slightly better. More or less 4 hours of screen on time and I stream about 20GBs per month. as long as I can get 3.5 hours of straight screen on time one spare battery will be more than enough.

I plan to avoid wireless charging because the slow charging creates more heat in the battery and speeds up its demise. Maybe we'll have wireless Quick Charge some day
[LG V20 Guides, News, & Discussion] spexwood:
The second part was already disabled, but the first part had a lot of stuff enabled. I think some of the apps I had enabled required Usage Access though (ill find out when I reopen the apps I guess). Google Play Services WAS enabled though.

What does Usage Access do exactly?
[LG V20 Guides, News, & Discussion] KOLIOSIS:
I'm guessing snooping on virtually everything you do on your phone,for better spam targeting ...................
[LG V20 Guides, News, & Discussion] spexwood:
... Scary!

Ill try my phone tomorrow to see if there's any improvement now. This phone has been nice, but the battery life has just been deplorable. I came from the Note7, and I was going to bed with 50% battery. Now I'm leaving work with that same amount, and going to bed with 20-30% (with a 30min charge on my way home from work ). :(
[LG V20 Guides, News, & Discussion] KOLIOSIS:
Worse case scenario is if an app isn't working, you'll likely get a pop-up telling you to turn on something/grant permissions, much like a newly downloaded app from the Google Play Store/system app used for the 1st time.
[LG V20 Guides, News, & Discussion] spexwood:
Thanks and I hope this works.

I went through the apps on the Usage Access list and opened them all and nothing has asked me for anything. One app did, but only if I activated a certain setting which I didn't want anyways.

I'll check in tomorrow night.
[LG V20 Guides, News, & Discussion] KOLIOSIS:
Even if you do get a pop-up telling you to grant access/permission,try backing out of whatever it is & try again:

I disabled Google Play Games & went to open a paid game (HOMERUN BATTLE) & was prompted to enable Google Play Games.

Since I don't play on-line,this struck me as unnecessary & I backed out to make the pop-up disappear & proceeded to play the game w/o enabling Google Play Games.......

Some things are going to rely on other apps permissions being granted to work,a good example is G-Mail needs all the permission in Google Play Services enabled to work.

However,I have Usage Access for Google Play Services turned off & everything seems to be working well.
[LG V20 Guides, News, & Discussion] lallolu:
While I totally agree that the idle time of LG phones are great, I noticed that from 99 - 100%, the calibration is wrong. You may have noticed that when the phone battery drop from 100 to 99, then the battery charge drops more rapidly.

I have an LG G4 by the way although I will like to update to the V20 at some time.
[LG V20 Guides, News, & Discussion] @rbiter:
I'm thinking it's the ay the fuel gauge is calibrated. Once it sees the battery drop to a certain voltage then it drops to 99%. I usually get about 15-20mins SOT before it drops. My best though is 50 mins SOT before it dropped.
[LG V20 Guides, News, & Discussion] spexwood:
I did notice a better battery drain today. I got home from work with 75% battery (with about 30 minutes of SOT during lunch) after a 7hr work day (a slightly short work day). So definitely a big thanks for the Usage Access suggestion!

Oh, O should note too that when I got home, I was watching YouTube for about an hour or so. That and a few phone calls brought me down to 50%.

EDIT

Spook too soon. Phone was at 40% and sitting, screen off, on my lap while watching tv. Phone suddenly got SUPER hot around the 2nd screen and the camera, and battery level dropped down to 25%. I pulled the battery and rebooted and battery was somehow at 18%. Now I'm using the phone again and battery level has been stuck at 18% for a while.

I'm starting to hate the fact that my 14 day return period is up now.
[LG V20 Guides, News, & Discussion] dbornack:
Made it 29 Hours with just over 5 hours of SOT. I'm pretty happy with that.
[LG V20 Guides, News, & Discussion] spexwood:
I did two things last night and today my battery has been pretty good. 8 hours in and I'm at 88% with phone mostly in my pocket. Android OS is only at 1% and highest drain is Phone Idle (not sure if that's good or bad though).

What I did was first disable Backup My Data under settings- Personal_ Backup and Reset- Backup My Data. (I also disabled Google Backup Transport in Apps just to be safe). The second thing I did was drain my battery until phone shut off, and then kept turning the phone on until I stopped seeing the LG icon. Then I charged to 100% with the phone off.

One of these may have helped. Knock on wood.
[LG V20 Guides, News, & Discussion] KOLIOSIS:
As long as you're not losing any desired functionality, that's the main thing, JMHO.

Just a few years ago, seemed we had to choose between the two.

Not so much anymore.

Doze seems to have taken battery life to the next level, & with the ability to exempt Doze on a per-app basis, we have the best of both worlds.

I don't make any settings choices just for the sake of battery life & functionality be damned. If a phone performs that poorly out of the box, it goes back.

My guess is those who have reported battery issues simply don't have anything wrong with their phone, other than literally having it on, screen on, non-stop use, using known crap apps such as FB & the like, & wonder why they're sitting on empty by noon. To those I say "put your phone down/in your pocket for a while & get a life/job".......
[LG V20 Guides, News, & Discussion] spexwood:
You aren't saying that I'm one of those "put your phone down" people, are you? :(

I most definitely have a job and am having issues with my battery due to something other than constant usage. (And I disabled Facebook too, lol).

I had heard too that 7.0 had battery bugs in it that plagued the Nexus phones. Any idea if these would affect us too? I'm eager for 7.1 to get released on the V20 because I suspect a bug somewhere, somehow.
[LG V20 Guides, News, & Discussion] KOLIOSIS:
No, not at all, I got that you were a phone user, but, don't literally live on your phone.

I was merely commenting on those who live on their phones non-stop & are dumbfounded when the battery gets low before the end of the day. Doing such on any phone will result in the same.

I'm glad that you could find a couple of tweaks to build on what you have without sacrificing performance or functionality.

ENJOY! :highfive:
[LG V20 Guides, News, & Discussion] Dark Jedi:
I just thought of this and wonder if anyone brought it up. I know with older phones I had and rooted devs put the double tap to wake the screen on. I know this could be a potential battery drain. Beings this phone has it stock. If you haven't disabled it. Maybe try and disable it to see if it helps with your battery drain.
[LG V20 Guides, News, & Discussion] spexwood:
I was thinking about this, but because LG embedded the knock on feature into the software, I would think that it would be optimized for the least amount of battery drain (if any). Compared to adding the feature to software that didn't originally have knock on embedded (like adding it to a Note 4 firmware or something), then I'd expect battery drain due to no optimization.

Still, maybe it adds drain nonetheless, despite optimation by LG. I'd be willing to try it since I'm not used to knock on and often forget I even have the feature.

How do you disable it?

EDIT: Nevermind. Found it under Display settings. Easy to find, lol. I'm going to try it off for a while to see if there's any dramatic difference.
[LG V20 Guides, News, & Discussion] rushless:
When the device is in sleep mode that is nominal weight of total power consumption, so doze should only make a difference if using the device for a prolonged period with no power source to charge. Normal daily use it should make little difference.
[LG V20 Guides, News, & Discussion] Dark Jedi:
This is from disabling double tap to turn screen on and turn 2nd screen off when main screen is off. Must say not bad
[LG V20 Guides, News, & Discussion] koppee1:
Have you tried uninstalling one app a time just to isolate the battery drain? Or go to mobile data and turn off background data for the ones that don't need it.

I've experienced that phone feeling hot and noticed a drop in the battery. And immediately checking the battery usage, it was always one app. Developer said they haven't done any testing on nougat yet. And suggested to give usage accessibility to keep it off. But turning it on gives a notice that they can get a lot of my data etc so I got scared and didn't do it.

Ended up downloading Greenify (which one purchased anyways previously) to auto force close the app when screen is off. Never saw the problem again.
[LG V20 Guides, News, & Discussion] spexwood:
I have the exact same apps on this phone that I had on my Note7, which never had issues like this. So I'm pretty sure it isn't an app issue. Plus, no specific app is showing up in battery stats. Its all Android OS (currently), Phone Idle, or Google Play Services (seems to have been resolved now).

I always disable background data for certain apps too, so that's done already.

I just ordered a spare battery kit. I'm thinking that I may have a bad battery.

Edit: I'm also experiencing weird battery drops when rebooting. After I reboot, the battery is 10-20% lower than it was before the reboot. This is another reason I suspect the battery. Thank God this battery is removable though. It's easy to diagnose a battery issue by swapping the actual battery rather than swapping the entire phone!
[LG V20 Guides, News, & Discussion] nicholb:
I think I finally found the app draining my battery. It was difficult pinpointing it as the usage always showed up under Android system. I've been using Greenify to kill background apps a few at a time to find the culprit. Looks like it is State Farm's "Drive Safe & Save" app. So far my battery usage since killing it has been more along the lines of what I would think is normal for the phone.

I also looked at the reviews for the app and there are several complaining about battery usage. Looks like the app constantly does Bluetooth searches for the in-car device, and lots of location checks. even when not driving. I'll see if waking it up every week or so is enough to keep the insurance discount for using the app.
[LG V20 Guides, News, & Discussion] bigboi3021:
Is there another build of Forcedoze because the description in the PlayStore explicitly says that it doesn't work on Android N.
[LG V20 Guides, News, & Discussion] spexwood:
Developer told me that he will update it once his S7 Edge updates to Nougat. I asked him some questions on his Forcedoze XDA thread.
[LG V20 Guides, News, & Discussion] hotstocks:
My only complaint once again is that sure while dozing or off battery life is fine, but as soon as you use the phone, good luck getting 3 hours of gaming or 4 hours of anything else out of it. When deciding to use an LCD instead of an AMOLED screen, they reall F#cked up. They should have made the battery at least 5000mah to cover the LCD drain, and it wouldn't have made the phone much thicker if they made the battery the whole size of the innards.
[LG V20 Guides, News, & Discussion] @rbiter:
Lol. I'm not sure about gaming but my worst battery life has been 4.5h on a rough day with various usage and mixed auto and fixed brightness and still had 28% when I got home. Best is 8h with single digits left. Usually get 6h+ with around 30% left by the time get home around 5p or go to bed at 9pm. Last weekend I had 7h SOT with 25h off charger and 29% when I put on charger finally. That was strictly LTE web browsing and a few minutes phone calls. All these times are on LTE. I get about 30% less SOT if I use wifi mostly/only. Not even rooted yet for greenify benefits and xposed.
