I upgraded 3 days ago and my battery won't last the whole day. As I am writing this (11:45am) I have around %30 left. Piece of advice if you have lg g4 (815): Do not upgrade to marshmallow.
[G4 General] ile89:
Yes, same here. I get only 1-2 SOT with marshmallow,and Phone heats a lot. Even when im not using it. I think it has something to do with mobile data/WiFi running in backround, not sure. Now back to lollipop
[G4 General] babadudu:
just wondering for those of you that says you are back to lollipop, are you just going back to stock (815) or is there a certain rom that you guys treasure ? my phone lasts me all day but that is because i don't use it that much anyways... so 2 hour screen time is fine on daily use, but when i am out and abouts weekend this battery life is really not ideal ..
[G4 General] Vseprz:
I have the H811 now on 20i marshmallow stock rom. Got 5 hours sot, 11 hours on battery today with mostly wifi and some data. Brightness was on auto. No battery tweaks.

Quite satisfied.
[G4 General] ile89:
I downgraded back to stock. IMO 2 hours or under SOT is unacceptable. Never had such bad battery life on any normally working phone. So there must be something odd going on, after updating marshmallow(2 times factory reset). not with all users, but I wasn't lucky enough. Hope that future updates will fix this big problem.
[G4 General] r27kul:
MM V20e with LGUP: 60 hours since full charge, 3:30 hours of screen and still 5% left. 30 min of talk, internet on wi-fi and 3G, GPS for Strava 2 hours, etc.

Stock rom and i can not be happier with this phone (only 3 days have almost passed, so i will still test it, but seems the best ever).
[G4 General] caezar:
Can you tell me where you found V20E image file for LGUP flashing? Thanks

[G4 General] Zenouzenou:
To me it's pretty clear, when i'm home battery life is a beast (5hrs SOT).

But on LTE or HSPA at work it's awful, less than 3hrs..

H815 V20D
[G4 General] sugarcos:
Same here..3g/4g ruins battery. Could be an operator network implementation problem. Mine heats a lot in the upper part (back and front) when using it on 3g/4g more then 10 minutes
[G4 General] DoKaTSuYa:
Exactly, same things !!! Which operator do you have ?
[G4 General] Zenouzenou:
I'm with Orange france.
[G4 General] Silvestrus:
Same experience over here. Decent battery usage on WiFi and horrible on LTE. H815 v20d
[G4 General] Bramzzz:
With mixed use of WiFi and 4G, driving with GPS and some youtube, still going strong! ?
[G4 General] lepixable:
4 hours 30 min SoT using only wifi. Im on 20d.. Not the best performance but it's ok
[G4 General] Oscar Shih:
i simply tested battery life on v20c compared to v20b. sorry about my English.

PCmark battery life is about 5 hr ~ 6hr . it sometimes reach 6hrs but sometimes 5hrs, and the temperature is about 37 degrees Celsius.

This result almost have no change from v20b.

Game playing was about 2 hrs on v20b , now it is improved to 2.5hrs on v20c . Temperature was 49 degrees Celsius and now is down to 43 at maximum.

(same game , same play mode , same 60 frame rates running)

Monitored by Resource Monitor Mini Pro . Brightness 50%.
[G4 General] zuqka10:
Confirmed! gain is 15-20%. Renamed the logd to logd.bak with root Explorer.
[G4 General] Heisenberg420:
Removing logd completely disables the logcat. Wonder why it causes so much drain in marshmallow.
[G4 General] tjsuominen:
I truly hope those MUST have fixes are delivered to "non-root" users like me through 6.x updates and rather soon. WITHOUT the need of resetting the phone...

Fingers crossed.
[G4 General] iteam:
I believe it's NOT possible to do this without root, correct?

Also, what advantages and disadvantages to expect if this was possible without root? Curious....
[G4 General] madphone:
For me battery life is unpredictable. The whole phones performance is unpredictable. I have used nexus phones before but thought OEM ROMs would be much more polished nowadays.

Sometimes i have pretty good standby on par with my nexus 6. all the sudden i have battery drain, and only 1,5h SoT a day, without having changed anything. On good days i have 3 to 3.5h (compared to 5-6h on the nexus 6). I have tried a, b, c, and d ROMs, more or less everything the same.

I have to constantly toggle GPS, Bluetooth and Wifi, otherwise, if i'm not lucky, i will end up with a dead battery after some hours. For Example, yesterday my lockscreen weather didn't refresh, thought i give it a shot enabling gps. but in the end GPS was used for 10hours, the phone didn't go to deep sleep.

I have to constantly baby the phone, to make sure it doesn't go nuts. It reminds me at the very beginnings of my android experience (galaxy s one). UI performance is also unconsistant, even simple things like pulling down the notification centre can make the phone lag like there is no tomorrow.

Marshmallow should have made android more predictable, especially with doze, preventing apps to suck battery in the background - and actually it did: on nexus phones, but not on the g4. I'm very disappointed!
[G4 General] Heisenberg420:
Correct.. If it were possible without root the only repercussions would be your device being unable to send stack traces to developers through Google Play.
[G4 General] mrjasenr:
My battery has been horrible since update. From the time i woke up. 4:18am. Went to gym, and got to work looked at phone around 8 am. Down to 83%. Sot under 30 minutes. Not pleased.
[G4 General] iteam:
very frustrating!!!
[G4 General] matood:
Battery

I got marshmallow update just few days ago from telekom, its 20d version.

Battery performance is very good indeed, almost twice as was in lp. Performance is pretty consistent and rock solid.
[G4 General] iteam:
Is it an AT&T 810 variant? those number are 5 times greater than mine after 3 days.....
[G4 General] pikachukaki:
For battery life is simple....remove the freaking FB...im getting +1H SOT....believe me i even couldn't believe it my self!!!
[G4 General] iteam:
For UN-ROOTED users try:

Going into >all settings>Storage>clear cache, then,

head into settings > about phone > and disable “Activity logs” which is causing the drain mentioned,

Then REBOOT!

I'm attempting now!
[G4 General] mrjasenr:
Look at percentage and sot. WTF
[G4 General] iteam:
That's what I say!
[G4 General] sstanton86:
Just throwing it out there, but sot is deceiving. As it doesn't take into consideration many other factors. In your example your phone was off charge for say 3hrs40m, but the sot of 30 mins doesn't take into consideration if you were streaming music, Bluetooth or the bad signal (normally the case in gyms).

Just my 2 cents obviously.
[G4 General] KarlDag:
That doesn't really mean anything. I can get close to that too, both on marshmallow and lollipop, if I use it for 5 hours straight after it's been charged...

you're not getting this on top of 20hours of standby time.

For me, MM has been very hit or miss. Sometimes I get great standby time, and sometimes I get rogue apps (including Google App!) sucking 5% of my phone within half an hour.

I upgraded for doze, but since it's not doing more for me than greenify was, I'm downgrading to lollipop and will keep enjoying viper4android.
[G4 General] iteam:
I unplug my phone after cleaning the cache and rebooting (while plugged in) then drive 45 minutes to work with my phone in my pocket the entire time and when I take it out of my pocket its warm and the battery drained 10%!!! WTF:mad::mad::mad:
[G4 General] maverick1103:
I've just recently purchased a G4 and it's my first day with the device, I had to stick my phone on charge at 1:30pm and I managed 2:30 SOT; I'm aware that it is very early days and things will improve....

Coming from an iP6s+ I knew the battery life wouldn't be as good because Apple's are Apple's and Orange's are Orange's....before my iP6s+ I had a S6 and that was near enough the same, any high usage resulted in having to charge the phone once or even twice in the day....

I will add though I still much prefer Android to iOS, the only thing iDevice's have over Android is battery life and we all know why that is.
[G4 General] iteam:
Now after 5 hours of NO use since unplugged I am at 63%, this is Unacceptable!!!! Says my screen is the highest percentage then google services and I've been on WIFI as well. Usually I get home at the end of the day and its around 55-65% with a fair amount of use before the upgrade. I don't know what to do at this point as I've been running MM for 4 days.....
[G4 General] ciprigeorgiu:
Have you done a factory reset after the upgrade?
[G4 General] leroybrute:
Be sure to uncheck wifi scanning in the advanced wifi settings. Big resource hog.
[G4 General] iteam:
No I have not. I've never had to do that for any of my many android phones ever. And never had I had a battery as bad as this after this upgrade.. It was perfect before.... It's clean and optimized as well... Now I'm at 45% after 6 1/2 hours of the phone being on..... NO USE at all. Only thing I've noticed is it only gets hot while away from WiFi.. But it still drains in WiFi connected areas just sitting there doing nothing like crazy as well...

---------- Post added at 01:15 PM ---------- Previous post was at 12:46 PM ----------

Backing up all my crap and possibly going to try a factory reset.... Not what I feel like doing LOL:eek:
[G4 General] ciprigeorgiu:
You should know that after a android version change a factory reset is recommended. I alwaus do that and never had issues.
[G4 General] iteam:
I get it.. I was a Flashaholic for a long time, so I know the drill.... I've just never experienced a battery drain even close tom this, guess I'm in denial to try LMAO, just hope it fixes any issue(s) I have in the end.... As usually newer revisions of custom or OEM roms have fixed my problems if any in the past..
[G4 General] james_007:
Im using h815 on V20a version, and battery life is terrible.

Can I now flash V20c because I read it has best battery life time?
[G4 General] DaveG46:
Just started reading this thread, giving a few of the suggestions a go, not sure how much good they are but battery doc app says these are running (pic). Think I only had Internet & settings open at the time

From this to fully flat with apps closed wifi and data off by 7:40. [emoji45] activities log turned off
[G4 General] ciprigeorgiu:
Light use over wifi in 2 days off the charger: i used facebook, 9gag, xda youtube.
[G4 General] iteam:
Impressive! Well I don't wanna jump the gun but I performed a factory reset and restored all my data and apps rebooted and did a full charge last night and my phone has been off the charger over 2 hours thismorning with 100% battery still!! So far it seems it was way worth the hassel...:good:
[G4 General] ciprigeorgiu:
Glad to hear that. Give it 2,3 cycles then judge the battery life.
[G4 General] iteam:
Will do. Thanks for the "PUSH" to do a factory reset! 3 1/2 hours of light use and still at 100% Would be at 65% or so yesterday....
[G4 General] sstanton86:
Just hit 5hrs screen on time with 5% battery left. I'm happy with that! All stock too.
[G4 General] Bramzzz:
First charge without the facebook-app and managed 30 mins more as usual! Not complaining!

Guess it works, just add a shortcut from the built in internetbrowser and you're all set. Disable Chrome too though!
[G4 General] sstanton86:
If you do it from Chrome though, you can get web based notifications just like on the app!
[G4 General] Bramzzz:
Tried Chrome, but it seems they disabled the shortcut widget after an update, so I can't make one? Any suggestions?
[G4 General] leroybrute:
Open chrome, go to your Facebook page, tap the 3 dot settings top right of browser, scroll down to " add to homescreen" and select
[G4 General] WTF?:
If you are rooted and bootloader unlocked so that you can block ads and debloat rogue system apps, and also keep junk apps like FB and FB messenger off your phone, then you would have discovered that all versions of MM get great battery life on LG G4.
[G4 General] gerhard_wa:
Fully agree on the FB crap. Clean out Chrome too and use Opera mini and you will get even more amazing battery time, much better than you could get with LP! Chrome turned out a real battery hog a week ago or so for me. Just out of the blue it would typically grab twice the amount of battery as the screen uses. Opera mini is down to about one fifth of what the screen uses.

Maybe the Chrome problem was just a thing for me, but I have never seen a web browser as light on the battery as Opera mini. Perhaps it has its limitations, but I pleased with it so far anyway.
[G4 General] WTF?:
The only Google apps I use are an old version of Maps before they ruined it, the Play Store. and the Sky Map app - all other Google apps have been removed.

For web browsers on Android, my favorites are Dolphin, Puffin, & Firefox
[G4 General] gerhard_wa:
I tried Firefox before I Installed Opera mini and that was the smoothest browser I have seen in a long time, smooth as butter! Sadly, it was almost as battery hungry as Chrome. :(
[G4 General] WTF?:
try Dolphin & Puffin - Dolphin is the best mobile browser I have ever found, when using a mobile user agent, however if I want a beautiful desktop user agent on my phone which looks identical to using a desktop, I go with Puffin - although you need to likely adjust DPI down to have a beautiful huge screen view - for LG G4 the ideal DPI is 538 (the screen's native resolution)
[G4 General] Jim84:
Hi how do you adjust the DPI?

Can't seem to find anything about DPI in setting
[G4 General] parisstc:
adding my 2 cents in this discussion,

After upgrading to marshmallow I didnt notice any improvement in battery life (I actually noticed a slight decrease in standby capability as overnight there was 2-3% drop compared to 1-2 that was before the upgrade).

I kept marshmallow for a couple of weeks without seeing any benefit and at some point I decided to give a try to a factory reset as I kept reading many people talking about benefits that I didnt see.

After the factory reset, I noticed a major improvement in battery life. Overnight the phone stays without change in battery percentage, the on screen time is at least 1h more with the exact same set of applications and kind of usage.

Currently my G4 has the same battery performance or even better than the G2 I owned previously (from which I didnt have any complain at all).
[G4 General] caiko:
So Inhave to do a reset after updating to marshmallow?Cuz my battery life is horrible after updating!
[G4 General] parisstc:
this is the first thing I would do before surrendering to crap battery life :)
[G4 General] sstanton86:
Curious whether this would apply to me. As my phone was new out the box, and just started updating all the way to mm v20d. Battery life fluctuates between 4.5-5hrs.

Will try to factory reset when I get back to see if I can squeeze anything else out of this beauty.
[G4 General] maverick1103:
Same here.
[G4 General] WTF?:
well fortunately my phone is bootloader unlocked, so I did even more than a factory reset - I did a full wipe in TWRP (everything except internal and external SD cards)

---------- Post added at 10:37 AM ---------- Previous post was at 10:30 AM ----------

I recommend the build.prop editor app - and then go to the menu in the left corner arrow and change the value of ro.sf.lcd_density from 640 to 538 and then power off phone and then power on - it should have smaller and much sharper text and much more screen real estate.

Note: you need to be rooted to do this.
[G4 General] elvirr:
Proud owner of LG G4 but...

Was using Meizu M2 note where I could easy achieve 6 hours on screen time, and decided i need more power so i bought lg.

Updated to marshmallow (v20d) and my battery was really bad. Then i did a reset to factory settings thinking it will be better, but the battery is the same, max.2.5 hours on screen time and the phone couldn't last more than 12 hours.

Then i turned off activity logs, uninstalled lg health, disabled search, voice and etc.history in google app, disabled google apps which i don't use (music, news, games, movies), deleted facebook app (leaving fb messenger), gps using only networks and voila!

I am on 60% battery left with 2 hours on screen time and 9h using the phone since i charged the phone :D

The phone is great and i like lg software but it's the apps which are making wakelocks and battery drain. I really think doze is not helping with this phone because i was using lg g3 earlier and the battery life was the same without doze.
[G4 General] Cozmos23:
Noticed the biggest gain when deactivating logs.

Most underestimated possibility.

I don't use facebook but I have often read that it sucks battery like hell.

But a big plus is that I don't see any difference when using 4G or 3G.

It doesn't effect the battery life at least for me.

With heavy mixed usage the battery lasts for 1 day with 3-4h sot and auto brightness. Used alot outside with bright enviroment and music, streaming, hotspot, GPS and browsing.

Could be better but its ok.
[G4 General] doomalikaw99:
Im currently on v20d and the last 2 nights were ver bad.my battery is draining at <20%!!I checked gsam,doze was enabled,and logd was draining the most yesterday and android system today(logd was far begind this time).Can anybody help?
[G4 General] InTents:
I would check with a logcat what logs are being generated to see if there is an app misbehaving or a permission that is being hit.

If you prefer using ADB then just type: adb logcat

Otherwise there are apps on the app store that you can use.

Keep in mind, not all apps abide by the new permission control of Marshmallow.

Another thing you can disable is activity logs.

Settings -> about phone -> disable "activity logs"
[G4 General] milan187:
Where can I deactivate logs?
[G4 General] aeron16:
the steps are right there in the post just prior to yours?
[G4 General] Cozmos23:
I meant disabling the logd process. There are some guides in this forum. Look for "disabling logd"
[G4 General] doomalikaw99:
Unfortunately ,needs root :/
[G4 General] milad2002:
It's really irritating...

I lose too much battery in M...

i also did reset factory couple of times but i get 3 hours screen time over data on ... I don't think it was the same in L...
[G4 General] milan187:
Unrelated but why do people say MM and LL when as far I know its Android M and L...

Just curiosity on where that comes from.
[G4 General] milad2002:
You're right...

Edited
[G4 General] Bramzzz:
I think this is the craziest I could get, if I keep the screen on it'll probably hit 7 hrs SOT

Removing Facebook and Fb messenger really made a big difference! ?
[G4 General] doomalikaw99:
MarshMellow ;LoLLipop
[G4 General] ObiDanKenobi:
Your kind of rude man. If you cannot/will not do what other do, that does not mean other cannot have way better battery life than you have. For instance right now I have 42%, 12h since off plug, 3:20min SOT, 20 min talk, 40 min of listening mp3. 3g on all the time, 2g when WiFi is on, sync is on, 2 emails push notifications, and whatsapp push on.

So it is possible. I do not get 6:30 regular on thia setup, rather between 5:30 and 6h SOT.
[G4 General] milan187:
48 hours of standby with WiFi and cellular on and battery is 85%, did not need the phone, screen on maybe 5min. I did not need the phone so just left it to see. Did not disable anything.

I guess thats not bad for standby, it can maybe go 10 days, but really what good is it for real world use... I guess its doze in action.
[G4 General] WAIDroid:
With my test i used Plex with my PC as a home movie server and with Lollipop i get 6hrs and 31mins of screen-on time :)

Now with gaming and such i don't know as i don't game

Please look at thread for testing and more http://xdaforums.com/g4/accessories/2-extended-batteries-test-t3320662

M

And found out that the problem is the data...

When it's on Wi-Fi there is no problem...but when it's on data it really loses battery...

It wasn't like this in L
[G4 General] TonyStark R.I.P.:
This thread is specific to Marshmallow Battery life discussion LG-G4!

Lets not make this personal.

It is impossible for any two people to get the same battery life.

While I've had mine (from the start) I too can get AMAZING battery life... When all I do is use it for messaging and 1 game, Backgammon. I'm not a heavy text guy, just with the family for the most part. My best was 4.5 days and I still had 20% when I charged it. The phone was never turned off in this time-frame.

Point is, nobody uses theirs like I do. That said I'm not hear bragging about my Amazing battery life, because I've also needed to charge it after a day with HEAVY 4g usage.

Threads like this should be closed. They are so subjective and only lead to where some have decided to bring this one.

Thread cleaned. Bring it back to a less quarrelsome thread please.
[G4 General] benjatt:
I'm so frustrated with this. At first I was losing 20% overnight on WiFi and 4g. Hard reset and all the fixes I could find and I had one good day of battery life. Now the standby drain is gone 4% on on WiFi O/N but my battery lasts about 6-8 hours with 90mins SOT. The main batter use is by Android os, Android system, play services and screen! Probably end up with another hard but come on how could the battery life get so much worse when one of the features is doze?
[G4 General] milan187:
I'm going to try stock launcher to see if its better then when I use Nova.
[G4 General] WAIDroid:
I'll try the stock launcher as well. Using a different launcher will use more battery but not that much. I wish we could replace the stock launcher but you have to be rooted :(
[G4 General] benjatt:
Help!

As you can see the android system is burning through battery. All I've done is read the news apps for 30mins.
[G4 General] ObiDanKenobi:
You read for 30 min, but Google app did his thing also. Stop it, tame it and you will have better battery life
[G4 General] milan187:
Do you mean force closing the app? I don't think that's the solution. I don't understand why some people are getting great battery life and others like me get at best 12h with minimal usage. Even tried a factory reset 3 times.
[G4 General] Cloudstrife:
Because those people know the trix to get that kind of battery life and then brag about it. They turn down the brightness to absolute minimum and turn off everything, like wifi, bluetooth, mobile data etc. etc or they do something else i don't know about. Then they have their screen on without doing much so that you get the SOT high... Normal good battery life for LG G4 is 2.5-4 hour SOT with 24'ish hour standby time. That's comfirmed for almost all reviewers that have testet the phone with normal usage. There is a difference between normal usage and getting as much battery life out of a device. One person even brag about gaming with he's phone and then getting 5-6 hour SOT hehehe.
[G4 General] caiko:
I am giving up in this phone.Battery life is pathetic.Bought a redmi note 3.
[G4 General] Cloudstrife:
¨Well... the phone has mediocre battery life as all reviewers say, but that doesen't mean it's a great phone. I use have medium usage on my phone and i at least last one day so it's like my samsung galaxy s5 and note 3... The alternative iPhone 6S is even more pathetic so I think we're ok.
[G4 General] 3mbers:
I've seen a lot of people comparing the G4 to the Note 4 in this thread. I've got both of these phones (note 4 being my 'daily driver' for the past 7 months) for the next few days and honestly there battery life is about the same (stock, no rooting etc). You're getting roughly 4 hours of SOT with both and no more than 24 hours of battery overall. I've only had this G4 since it was updated to Marshmallow but the battery performs pretty much as I'd expect it to
[G4 General] benjatt:
If only it was so simple as force closing an app. This is the first time Google app has come up so high. It just seems that the system is running through way too much battery, which stinks of a rushed product.

I did another hard rest and booted into safe mode. I'll let you make your own conclusions. See attached :
