Get great battery life after disable gps (using network based location) and disable smart setting too.
[G4 General] 0rigin:
I have the exact same problem, haven't found the culprit yet. For the first two weeks or so I've had a great battery life, then all of a sudden, it all went downwards. Rooted & debloated.
[G4 General] Sfkn2:
Google Now or location settings?

How do you disable google now when you plug in your headphones?

Whenever I plug in the headphones, and try to put it on standby. It turns back on with google now. (Headphones with no microphone capabilities)

I looked all over google settings and the delete cards options, but couldnt find anything of the sort
[G4 General] 0rigin:
Google settings app -> search & now -> accounts & privacy -> Google account -> sign out

Never gets turned on for me. I got hotword detection turned off too, maybe that's your problem.

Also, found the culprit for my high battery drain issue - it's WiFi. If it's off, battery drain is normal, if on & connected, kernel & Android OS go berserk. Only happens on this phone. I'll reflash when I find the time and see if the problem still persists.
[G4 General] spartan268:
Thanks this worked. I went on a google crusade and none of them bothered pointing me off to there. I was originally under the impression it will sign out of EVERYTHING google related. But it didn't :)
[G4 General] greydarrah:
I just discovered this same problem on my G4. Having WiFi turned on is killing my battery. Being on limited data, I need to find a solution.
[G4 General] neflictus:
What are you people doing ? I see 5h and a half of SOT. Brightness at 10%? Watch movies ? I can't get past 3h and a half. I know all the battery tricks and tips.

On the galaxy S6 i got 6 hours of SOT every day, using the same apps.

G4 seems to just suck at battery life.

From LG H815
[G4 General] rfarrah:
I'm on wi-fi 24/7/365. No issues here at all.

You might want to double check your settings, if you haven't already. For example, under Wi-fi > Settings > Advanced, I keep "Wi-fi notifications" and "Allow Wi-fi Scanning" OFF (unchecked), and "Avoid bad Wi-fi Connections ON (checked).

HTH
[G4 General] akyp:
Same here. Either I have a really bad battery, or really bad S808, or both. I can never get more than 3h SoT over 1.5 days compared to some people here who can get >5h SoT over two full days. Did every battery saving trick in the book.
[G4 General] greydarrah:
I do have those WiFi settings as you described. One thing that seems odd to me, even with "Allow WiFi scanning" off (unchecked), I notice on the main WiFi screen that it says "Searching" every 10 seconds. Does yours do this? I don't know why it would search when it's connected to a strong network and you told it not to scan.
[G4 General] neflictus:
People getting over 5h of SOT are probably watching youtube videos at low brightness and / or are not using the phone in bright sunlight.

Over 95% of people are getting a maximum of 4h SOT. I sold my S6 to get this phone. I punched myself in the nuts.

From LG H815
[G4 General] rfarrah:
Yes, I do see mine doing that when I'm on that screen. I assume that goes off when I navigate away from there or have the screen off, but I don't really know for sure, I guess. I just know I'm not seeing the battery drain that you are experiencing.
[G4 General] juju2011:
Mine does that as well and I don't see avoid bad connections anywhere also my battery life is atrocious on WiFi but amazing on data -_-
[G4 General] zero1000100:
I have very mixed usage as I use my G4 as my primary device. I can get over 5hrs SOT and that's using my G4 any way I please. Now, there are other times that I don't get 5+hrs SOT. My settings are on page 14. You can see that I keep my Brightness on 50% at all times with Auto off. So no dim screen over here. Sometimes I have to adjust the Brightness up for short periods of time if I happen to be outside. It's never for long durations so it doesn't impact overall battery life. I also put a screenshot showing straight YouTube usage with over 5hrs SOT.

I simply turn off all the stuff(bloat) that I don't ever use. Your mileage may vary but if you adjust your settings like mine then 5hrs SOT is definitely possible.
[G4 General] KindleTester:
I'm interested in the device but the battery life concerns me, if anyone can provide a diagram of a comparison between G4 and it is competitors in the battery life department it would be great.

thanks
[G4 General] Allesa:
I've got no diagrams or anything just plain personal experience. The point is, almost all android flagship took a hit this year since lollipop. Had a z3 and m8 and the battery reduced since lollipop to 5 hours give or take . This year's flagship aren't any better too. Had htc m9 and the battery averaged around 3.5-4.5 hours (firmware 1.4xxxl) regular s6 averaged 4-5 hours. My G4 averaged 4-5.5 hours.

I jump between phones so fast, yet I stuck to g4 the longest. Battery similar or better than m9 yet having higher res screen and far better camera, and having better UI and removable battery and sdcard compared to s6.

Also the power of 818p dual sim is a no brainer for me used to having two phones that I carry around. Managed to sell my secondary phone, finally.

IMHO, make your decisions on other aspects other than battery if you want to buy this year's flagship. The market seems saturated in terms of battery life after lollipop.
[G4 General] KindleTester:
it is been always like that with every new version of android the devices that get upgraded but not initially offered with that OS will suffer from battery life issues, but i agree if I'm buying now I should consider the other aspects other than the battery life.:good:
[G4 General] neflictus:
For me it is very simple. On the S6 I got 6h of SOT every day using the same apps. Debloated everything. Tweaked everything (no gestures, no tricks).

On G4 I get 3h 30 min (same thing, debloated, no smart anything, no widgets, nova launcher etc.)

I was just stupid thinking LG G4 was better than G3 in terms of battery life. It's the same mistake I made when I sold my S5.

Not going to happen a 3rd time.

I was having terrible battery issues but now its great. Debloat list is good and also helped by turning of VoLTE. (Using Canadian H812). Thanks everyone :)

[G4 General] spartan268:
Ahh I thought so. Thanks for letting me know
[G4 General] scarboy6693:
So I got an ATT model LG G4 when it came out and I've been following this thread since but I haven't posted but I figured my experiences with it so far.

So initially I had horrendous battery life like where my phone would drain 5-10% per hour on Standby and using it I'd only get 2 hours max of SOT as well as heat up where it was hard to hold and the random update made it worse.

I gave in and did a factory reset and it solved the heat issue and I was getting about 2 1/2-3 hours of screen on time after I disabled all the ATT bloat. NFC and Location are off too since I don't use either of those. I found the main thing eating my battery was wifi during standby even though I have keep wi-fi when screen off set to off and scanning off. I ended up making a tasker Profile that shuts off wifi when the screen is turned off and now its flatlining during sleep and SOT is up to 3 1/2-4. Could probably go a little longer but I use Bluetooth Audio streaming while driving with pocket casts or spotify and I have my moto 360 connected all day long too. It is a bit annoying to have to go through a few loopholes for the battery life but now I'm pretty happy with it.

Other settings I have for reference. Brightness I set myself and usually stays between 35-50%, Bluetooth Always on. I'm running action launcher opposed to the stock one.
[G4 General] Clay330i:
You should sell the G4 and go get a S6. Seems like a simple solution to me.
[G4 General] hasaang:
Go over the S6 forums. Seems like they are having some bad battery issues there as well
[G4 General] almizilero:
I went through the first 30 pages (first reading, then crossreading) and couldn't find any lists. Searched the thread for debloating and bloatware and came up empty. Can you give me hint what to search for?

Thanks!
[G4 General] tgfols:
I've managed to eek out 4 1/2 hours SoT and 2 1/2 hours SoT at 50% yesterday on Apex Launcher by keeping brightness between 15-20%, turning off auto sync and only letting certain apps sync when I use them, keeping Deep Sleep Battery Saver on slumber mode all the time, turning off Location services until I go on a run, turning location history off as well as BT, data, and NFC when I don't need it. I primarily use Reddit, Facebook, Chrome, G+, Gmail, Hangouts, Pandora on a daily basis and take a few photos throughout the day and I haven't had to switch on the battery saving mode yet, so I'm quite happy with my usage. I'm not completely compromising my experience, and I find that a slightly dimmer screen and a few extra taps to turn on certain functions when they're needed is well worth the extended battery life.
[G4 General] brysonwong:
Would really help if there's a list too. Can't seem to find the list.
[G4 General] Allesa:
Heads up. After rooting and looked at better battery stats alarm wakelock, I figured out fast dormancy turns on everytime after reboot. Phone wake lock goes berserk after restart, and disappears after doing the turn off dormancy routine.

Any way to turn it off permanently?
[G4 General] Johnny Broccoli:
Just bought yesterday. First day battery life looking decent so far. 2.5 hours screen on time with 50% battery left. Mainly using Chrome, Tapatalk, and streaming music over network from Google Play to a Bluetooth speaker. Brightness been between 75-95% the whole day basically.

Not rooted yet and no battery saver programs running or anything.
[G4 General] kmleon@:
I've been watching weird battery behavior on the end of day around 5% of power. It goes down to 3, after couple of minutes it came back to 4 than to 3 and again to 4. Within last 3 hours it dropped only by 2% (from 5 to 3) with half an hour of SOT. It is really weird...
[G4 General] enfurno:
I go through 2 batteries a day...Battery life is terrible on the g4, I can't say if it's completely the fault of the device though. Lollipop crippled the battery life on my z3 previously and that phone was beyond stellar in this category before said update. Bottom line, I never go far from an outlet without some sort of power backup.
[G4 General] hoangel:
My experience after 2 weeks using G4 (F500s Korea). Everything is fine, smooth, perfect in some criteria. I would recommend this fone other than S6 or IP6. However the battery is on the other hand, very mediocre & i really dissapointed. Its only last 4hours SOT or some day 5hours or abit more. Compare to Ip5c i used last month, this G4 battery life is worse. Sometime i have a feeling like if i open G4 & do something, the battery drain quikly, it consume me, man :crying::crying::crying::crying::crying:
[G4 General] drtchocky:
My battery life has been hindered by one thing: GPS

So the past few days I've run an experiment. At the beginning of the day I place location in "Device Sensors Only" mode, if I don't use any GPS using apps and go to Android System in my battery stats, it doesn't even show a GPS stat. If I use maps, it shows a few seconds of GPS usage. At SOME point in the day, and it doesn't appear to correlate with the launch with any app in particular, the GPS is prompted to run willy nilly, for hours. I'll start getting that "Finding Location" notification constantly and the phone will burn through battery and I'll get maybe 2 hours SOT and 9 hours battery life... and this is all with moderate to light usage. If I use the camera a lot, or stream video for a while, it will burn out in like 6-7 hours. I am sure my G2 didn't have this issue. Also, I never set Brightness above 70 with Auto brightness.
[G4 General] ufgators232:
Not sure if this is just coincidence or not, but I went into Apps in settings and disabled LG Health agent. I also started using nova launcher. Battery life has improved dramatically from one day to the next. Phone also doesn't gets as warm. I'm not a power user like some of you guys, just posting what I've noticed.
[G4 General] lallolu:
It seems WiFi has serious battery drain issues on 5.1.1

I noticed this on my oneplus one and I thought it was a cm12.1 problem but since you guys have the same issue with G4, it is safe yo conclude that it is a lollipop problem. I usually set "keep WiFi on during sleep" to only on battery but I noticed that the WiFi is always on anyway. The solution for me is similar to yours, I used an app to turn off WiFi when the screen is off for 3 minutes.
[G4 General] rfarrah:
FWIW, I am not seeing this at all.
[G4 General] 0rigin:
Lollipoop. I actually miss Kitkat...
[G4 General] Pyrres:
After root and Greenify+debloat Im getting quite excellent battery life. I don't even remember when I left my work with 75% battery left before this. Yes I got better SOT with M8 but it was smaller screen and resolution and not as bright. Cant complain much as my average SOT since I bought the device is 3h15min and climbing every day and that is including all the time it had bloat and really bad drainage in idle.

[G4 General] AnteusFogg:
Same here. T-Mo app is utter crap. Sluggish as hell and battery killer. I wish I could at least disable it :/
[G4 General] spartan268:
Anyone else seeing unaccounted wakelocks in BBS?

I have about 1 hour and 15 min awake time, and in the wakelock section only about 20 minutes of it is accounted for. Rest it can't seem to find. Was hoping to fix all my woes with root
[G4 General] Velcorn:
Well, since yesterday my battery life has been amazing; let's see if it stays like this. With around moderate usage I'm at 5 hours SoT with 20% still left.
[G4 General] greydarrah:
Did you do something different yesterday?
[G4 General] Velcorn:
Well, I changed my homescreen layout from using purely Zooper widgets to a "casual" homescreen but in terms of usage I haven't done anything different and Zooper didn't appear to drain battery that much. I was around 3-3.5 hours of SoT most of the time. Sometimes up to 4.5 but very rarely, even before using Zooper widgets at all.

[G4 General] Icepray:
so replaced my g3 with the g4 this week.

100% Stock

GPS on, bluetooth on, wifi on and off throughout the day.

Brightness at 50% auto off.

2.5 hours of SoT

Extremely disappointed I could get 3.5 on my g3 in the same conditions and I don't see the point of rooting to get the same amount as my g3...

And I checked wake locks and android systems etc...

Either the battery sucks but reading the thread I doubt it or my battery is defective.

I thought it was my charger (not using the one in the box) so I gave it a try with the one in the box, then I thought it was my backup, so did a phone reset, cleared cache and got 2.5SoT again when i hit 15%.

Sucks cause I really really like this phone and my g3 is dead so... gonna return in and pick up a moto G while I wait for the next nexus I guess...
[G4 General] Vijet:
With a quantum HD display, the SOT is bound to go down from G3.

When I got the G4 a month back, I got SOT of 2.5 hours as well, but gradually the battery life has improved.

I debloated the phone using the debloater tool, and also disabled quite a few battery consuming apps that I didn't use.

These are the apps I disabled manually (not debloated, but disabled using application manager)

Amazon App Suite

Amazon Kindle

Amazon Music

AppStore (Amazon)

Caller Name ID (Verizon)

Cloud (Verizon)

DT Ignite

Exchange

Google play books/games/movies & TV/Newstand

LG Health Agent

NFL Mobile

QuickRemote

SmartShare.DLNA

SmartShare.MediaServer

SmartShare.Provider

I can assure you that your battery life will improve significantly if you disable the apps from the above list that you don't use.

I got a maximum SOT of 5 hours, and I easily average SOT of 4 hours after these changes.

I use Wifi whole day, data if not connected to wifi, but GPS is generally off, and bluetooth I use occasionally.

Bottom line, the battery on this phone isn't that bad after all. It's just that some apps suck power so much that it feels the battery sucks.

Try these steps and the battery life will certainly improve.

Good luck! :good:
[G4 General] Icepray:
I skimmed through the list and I got like 1/4th of them as mine is the unlocked one, i only got LG apps which i disabled the maximum I could. I don't have verizon stuff or amazon etc etc...

Seriously might just take it back tomorrow and wait for Moto X play, I prefer a slightly worse camera and better battery than the other way around but I will test it out until tomorrow evening before going back to the store.

I've had it for a week now.
[G4 General] zero1000100:
Alright, so we finally got Root which is amazing. It has definitely made a noticeable difference regarding battery life. As soon as Root was released I immediately got to work and downloaded and flashed every ROM available currently for the TMO G4. I didn't really notice a discernable difference regarding performance or battery life. That was until I flashed the Global SIM Unlocked ROM released a few days ago.

Since flashing this ROM I have noticed a difference in speed and responsiveness overall. I also saw a boost in battery life which is always a plus. The ROM is already pretty lean but I froze/uninstalled a few additional apps to my liking. I'm still anxious to get some AOSP ROMs but this one will do for now. I really wish that I knew how to cook my own ROM or help with the process of unlocking bootloaders but unfortunately I don't. So I'm patiently waiting for the good developers on XDA to whip one up for me.

I'm mostly satisfied with my G4 especially more so now that we have ROOT. I was contemplating picking up another device but nothing currently available is appealing to me so I'm here to stay for now. Once AOSP ROMs become available I think that I'm going to be very satisfied overall with the G4 so I'm going to sit back and chill for now.

I don't like running my battery down super low so haven't purposely ran it down to below 15% without in-between charges and prefer easy math, so here's some screenshots showing my battery life after running it down to 50% on a few recent, typical days at work with the phone. With Bluetooth on, streaming music from the cloud, pretty heavy web browsing, battery saving location mode on, and at least 75% brightness I'm averaging a 5 hour SOT pace.

Hi guys,

I have the tmo G4 (H811) for two weeks. Battery life was horrible. Tried numerous things including factory reset.

The only thing that worked for me was disabling WiFi scanning and disabling VoLTE. This had made the biggest difference for me.

Now the battery life is at least decent and good enough for a day.
