my battery was down to 11%, so i turned my phone off and charged it for about 60 seconds through USB and now that i turned it back on it says 47%! there's no way it could have charged that quickly. this is on cm 6.1.2
i flash a lot of different roms but wipe data, cache, and dalvik before each new one. i don't run any unusual apps that would drain my battery and i have tried wiping battery stats every once in a while. ive also tried charging techniques such as charge for 8hrs, charge for another hour, etc. and nothing seems to work. my battery will drain in about 4 hours of moderate use (just web browsing and google talk while watching TV). im in an okay signal area, not using any 4g - happens with any rom.
this is a launch day evo battery but the actual phone (was 002) is replaced with my current 003 refurb.
im gonna try to wipe the whole sdcard and start from complete scratch.

i had this problem and when i checked to see what all was running i saw Google Maps was running... I didnt turn it on either but with a force stop and reboot im back to normal.
wiped sdcard completely, repartitioned, flashed latest cm 7 nightly, used for a while, charged to 50%, unplugged and in 20 minutes went from 50% down to 31%. had the same sort of behavior before on all roms. just display, cell standby, and android system using battery - not much else. maybe i need a new battery?

what pri and nv version are you on? that could be the cause.
I have admittedly only just re-flashed the ROM (full wipe beforehand) on this device and it's only been through a single charge cycle since I wiped battey stats after calibration, but I am still disappointed that after only 90 minutes of web browsing and im-ing I am down to 39% battery.
Should I expect battery life to improve in the coming days/weeks?

I'd try re-flashing the ROM again.
How would that change anything? I'm not saying it couldn't I just want to know how that could improve battery life since I would be flashing the same ROM, with the same kernel over the same radio...

I had the same problem with Cool Sensation v7 ROM. Battery drain was terrible after about a week of flashing it so I uninstalled all my apps planning to re-install them gradually, a few at a time to see which of them was draining the battery but it was still a problem after uninstalling all user apps. I then did a full wipe in recovery and reflashed the ROM, added the user apps gradually and my battery life is just great now.
Please define gradually. One app a day, or what?
Do you advise against Titanium restore of all apps and their data?
end_of_message / COMPUTOR4500
I tried re-installing about 3 apps at a time and then checking the battery drain over 24 hours. But, like I said, it turned out not to be any of the apps it was the ROM, but I can't explain why. Once I did a full wipe and reflashed the same ROM I could have just re-installed all the apps using TB anyway as it was the ROM flash that was the culprit.
What I actually did was - Full wipe > Flash ROM > Batch restore all apps that I've had for a long time using TB > Restored all newer apps (downloaded in the last 2 weeks) a couple at a time each day.
I didn't need to do the last step really because I'm convinced the problem was just a bad ROM flash.
Reflashing a ROM can help solve many problems, though I don't know the mechanics of this actual issue.
Right... Thanks man, I guess I'll just re-flash then.

This sounds about normal to me.
60% in 90 minutes isn't that bad.

Yeah I know, my phone drops 1% a minute under heavy use. That would be 90% in 90 minutes, taking into account my phone turns off at 20% you can see where I'm going with this.
As I said, its not that bad.

I'd say you need to calibrate the battery. My phone goes beyond 8% and doesn't turn off.

I use it and it has no alerts.
I've been using Insertcoin Rom, my battery just went from 90% to 75% in about an hour. I'd say 10-20 min heavy use, and the rest is just standby. I don't know if what i'm experiencing is normal or not, but right now i'm trying to find a Rom that has better battery life

How is the battery life after re-flashing the ROM?
Sadly it's still crap - I lose about 1% every 2 minutes.

Yeah it was constand web browsing for 90 minutes, just that it was over 3g/hsdpa and not wifi, but the drain is the same over wifi.
end_of_message / COMPUTOR4500
Hsdpa or rather mobile internet in general is a battery drainer. But with WiFi this is really high. With oxygen I have 10% per 30 minutes screen on using WiFi (brightness set to 25%).
I would recommend to try another rom.

It's GSam Battery Monitor, my phone drains from 100% to 95% in like 15 minutes. I found that one of the culprits was a Pansi SMS theme, and the other (the biggest one) was "Media", which drained 35% of the battery. The phone was kept awake for 7 minutes, and under included processes it says *wakelock* android.process.media.
Is there a way to stop this?

You can force stop media but that's temporally. You'll need to find which file is causing it (most likely one unreadable by your media player).
Could also be coming from your external sd card (if you have one).
Sadly sometimes the only solution is a full super wipe... did the trick for me (I needed to anyway)
Hmm...i do have an external sd card. But it's used for music video and downloads. There's no apps installed on it.
What do you mean by a super wipe? Is that different from a regular wipe? If not then I just did a cache/dalvik wipe a week ago.
How would I go about finding the file that's responsible for this?

Super wipe basically wipes everything of our internal card in other words going to TWRP and erasing data. Its basically just searching and searching on how to open the media so that's why its high.
Another option is to move all your pictures and videos and other downloads to your ext SD card. Then wipe data on the internal card and see if once you boot backup again and an hour or so of running if it isn't so high.
So I updated to Marshmallow on my LG-H815, and now my battery drain is a lot higher than on 5.1.1. I'm checking GSAM and it seems like Android System (logd) is using up the most battery.
The phone is running quite warm as a result, before, at the end of the day, my phone would be on around 60%, now it gets to 20%.
I can't seem to find much about logd, but so far I've disabled WiFi scanning, and checked to make sure Activity Logs is disabled.
Does anyone know what could help to bring Marshmallow promised battery life improvements?
Cheers.
I had a battery drain because of Bluetooth. After disabling it it's gone. It's only temporary solution because I need BT to use my SW2 smartwach. So LG do your job.

First thing is to do a factory reset after you upgrade to MM, my battery was worse until I bit the bullet and reset it. Now I get 2 days use with 5hrs screen on time, most of that on GSM data.
my experience with MM
Mine just updated to 20c (EU - Latvia) and its flawless! Had some battery drain at the beginning, now after 3 restarts it runs a lot better and battery life lasted around 15% longer! If someone have issue with processes called dex2oat as they running and eating up the battery, you will need to reset your phone to factory settings, reinstall all of the apps you had on Lollipop and restart phone few times. Mine disappeared next morning. I guess they were apps still optimizing for battery! Hope it helps!
My experiences with MM are:
1) Bluetooth drains THE **** out of our devices. If you don´t need it, disable it. No idea why, but with BT off, I have over 1 hours of screen on time time more every day.
2) Disable auto-brightness. Do it. Helped me to get from 2,5 h SoT to over 3,5 h.
3) Greenify really works for me. I know we have Doze, but Greenify affects system apps...maybe thats why. Or maybe it´s just voodo, idk.
Still, battery life could be A LOT better.
Well I've just done a factory reset, will see how tomorrow goes.

No improvement after a factory reset, may roll back to 5.1.1
In my case I did update from LL directly, battery was a disaster, disabled location services improved a lot. Found out how to do CSE installation with LG UP, reflashed the phone and disabled location services, battery is great...I end up the day with 40% with normal usage with WIFI at work.
I updated my H815p (south africa) to Marshmallow 6.0 using the LGup utility the first time I flashed I selected update only option, and I was getting unusual drain so I retried and this time opted for refurbish option which I believe is the fresh install option, and still only get 55 min screen on time. Android OS is keeping the device awake all the time. What can I try to solve this.

Factory reset, set it charge overnight, then goes to around 30% with 1 and a half hour screen on time. That's what I was getting previously. I've reverted to Lollipop.

thank you very much sir !
great solution without root !
Since getting the update my battery performance has been terrible. Its takes hours to charge the phone and when left off charge last night i lost almost 20% with thr phone doing nothing. When i use my phone the battery can be seen draining.
I have restarted the phone a number of times. Dont really want to do a hard reset though.
I have emailed LG and shall keep you all posted.
Hi,
I joined this forum just for this issue. I was all excited about the new battery improvement with MM 6.0 although my LG G4 had excellent battery life before - thought better is always a good thing.
Until I upgraded to MM 6.0 about a week ago. I thought I was just using my phone more as it kept being at 20% by 5pm when I was never less than 75% before?
So I started doing some reading and checking the battery usage and installed Greenify.
Last night I had my phone at 100%. Unplugged for 8 hours with no usage - I was asleep...
This morning battery was at 80%???
So I checked what is using the battery. The issue is that you cannot reset these items to zero but they do seem to fluctuate so this maybe a current usage? I pulled the battery for 30 seconds and the percentages are about the same.
Google Services 15% (I suspect my location services that are enabled but they were enabled under LL 5.1 and never killed the battery).
Next is a weird one com.lge.exchange 12% (I assume the exchange server I get work email on) - have always had it before as well if that is it and have not changed the sync settings which are manual so only get mail when I call for it)
Phone idle 12% - what is phone idle taking 12% for?
Cell standby 11%.
So based on a 20% drop over eight hours with ZERO usage other than standby - my LG G4 will last about 30 hours on STANDBY. No usage - just sitting in a quiet room.
Can someone help what is now sucking my battery dry all the time?
TIA

I have the same issue, after I did the V20D-JAN update a week ago. My SOT dropped from ~4h to less then one with "Android System" beeing on top of my battery history with 50%. I really wonder, what happened to my device.
I did a total of 5 factory resets, 2 full discharges (not hard, when your battery only lasts about 30min of continuous usage) and still, nothing changed. It even got to the point, where it discharged while on the wall adapter after a factory reset. I installed no apps, no root or nothing. Full stock after a reset and it dropped charge in no time.
Disabling location, logging, LG health and most other stock apps after a factory reset did not change a thing. "Andoid System" was at 40-50% battery usage in less then 15min after I booted the phone.
Anyone else had this, too?
I've reinstalled, reset, cleared cache nothing works. on 6.0.1 I would come home at the end of the day with 50/60% left. On Nougat I'm home and on the charger at 20% if I'm lucky.
I tried to downgrade to 6.0.1 but it wont let me. Any ideas? I'm lucky to get 2hrs screen on time, before I could get at least 5-6hrs
Try to disable unusefull apps, block their auto startup. As I can see in your shared pic, your gservice use a lot juice, so turn off auto ok google detection and other things what you are not use at all. I belive its possible to downgrade if this is your choice, but It requires the stock system file and Odin. And least Im happy with my screen on time, I can easily get 5 hours or more every day!
