30+ hours battery life...hoax?

So I have been searching and trying to get exceptional battery life ever since I got Android 2 years ago. I have tried so many different roms and kernel combinations and have always had "decent" battery life. But I keep seeing people claim 30+ hours of "moderate to heavy" use, and am completely baffled by how they achieve this.
An outline of my average current use
-stock Sprint battery
-CM7 GX.10
-v.0.0.5 SBC HAVS CFS Savage kernel
- conservative governor, 245 min clock 1036 max clock using built in CM7 settings
- no task killer, but I am running Auto killer memory manager (to tweak Androids built in memory management)
-minimalistic text widget updating weather every hour
- sync gmail, contacts, calendar
- gtalk running
- calendar widget
- 25% screen brightness
- wifi, 4g, & bluetooth off (I never use 4g or bluetooth, and turn wifi on for a few hours when I get home at night)
- sat on and "use location" enabled
- about 50 messages per day (gtalk + sms)
- 1 hour total of phone convo (off and on)
- 30-60 minutes web browsing and/or games
With this I can go from 7am unplug to 10pm plug in...but just barely. This is the best battery life I have gotten, and it's still nowhere close to what some others claim. I don't want to use ultimate juice as I don't want to loose gtalk and push gmail. I would LOVE to be able to switch 1x data on while the phone is sleeping, but i'm finding out the evo radio can't do this?
Am I missing something? Any special tricks to double my battery life? Any of the typical responses to improving battery life I have tried/checked. I have read way too many threads on the subject, and everyone is the basic "check away time vs up time", "wipe batt stats", "turn off radios", etc etc. I have thoroughly examined what has been using my battery and network, and can not find anything out of the ordinary. Plus this battery life has persisted through multiple roms and kernels, so I don't believe I have any type of "leak" from a rogue program.
I can not fathom a way to DOUBLE my battery life, but I see too many people claiming 30+ hours to think they are all lying.

Can't prove it but I got 34 hours using Caulkin's 1.7.7 with HTC #15 kernal and autokiller set to Optimum... then again I'm a light to moderate user
I also disable backgrounds so I am not syncing anything, using the stock battery .. people can " lie " but I was shocked to see how long it lasted

If you go to Settings, Wireless & Networks, mobile settings, Uncheck the always enable data.. what this does is turns off your 3G after 5 minutes of not being used to conserve battery even more.

This isn't an option in ASOP (as far as I know)

I've been playing around with Tasker to achieve a lot of what you're asking for. I use my phone a lot, though, so my batteries go dead on a regular basis.

maybe those who claim they get 30+ hours battery life use extended battery. i say this because i've been using the ebay extended battery and i get like 30 (real heavy use like streaming videos) -35 (moderate use) hours. i don't talk or text much.
on the stock batt, as far as I remember the best i got was like 20 hrs with very little use. that was on Myn RLS4 with net 4.2.1 kernel.

30 hours is possible. But not with heavy use and stock battery. No matter what you do
Sent from my PC36100 using XDA App

Here's what I can say:
Back before CyanogenMod 6.1, Snap 7.6 came out. During beta testing of Snap 7.6, Shift was able to get well over 36 hours on a single charge, and got the some of the highest Quadrant scores if I recall correctly.
Now, I don't particularly recommend going back to CM6.0, or Snap 7.6 for that matter. Snap v9 is in the works and is due out "soon". Until then, try just the CM7 nightlies and their kernel.
For me:
8-12 hours of battery life.
CM7 nightly
stock kernel
Gmail, GVoice, Vontacts, Calendar and Exchange mail/calendar on Push notifications.
Plume checking Twitter every 30 minutes
Automatic brightness
BT off, WiFi on for 1-2 hours
no task killer of any kind
Android Agenda widget, Plume Widget, Beautiful Widgets 4x1 home weather (updates every hour), BattStat widget, gTabSiMiClick widget, SetCPU widget
NexusKang LWP
SetCPU: 384min, 1113max, conservative. Screen off: 384-422. Battery <50%: 384-806. Battery <90%: 384-998.
Tasker running, as well as SeePU++, DSP Manager, and Prey.

It is through my gingerbread rom that is in my signature.. as for other people yes you can get 30 hours on stock battery but HIGHLY unlikely with heavy use..

hhhmmm, I've never seen that option on either CM6 or CM7, I thought it was a sense thing. Either way, I deff don't have it on CM7 GX.10
Even 24 hours of "moderate" usage would be great

30+ hrs i dont think so!!!! Personally i use netarchy's sbc, havs aggressive, cfs and i get 16+ hrs. Thats good enough for me. That 16+ hrs tho runs down to a single digit percentage.
I cant see 30+ hrs.....

with my combo (sig) i got 20 hours of moderate-medium use with 30% left. Those numbers really depend on how much standby u have. Also my battery life may get better after a lil while.
Also i noticed you keep GPS on. I keep mine off unless i need to use nav. Otherwise i let geotag/location based stuff use my data to get general locations. Itd prob save you a bit to toggle this when needed.

+2 Philly!..... 16-18 hrs.. i'm getting on Burnt Droid with SBC kernal....... i mean.. i pick up my phone off the charger at 630..i need it to last all day till 5..... and it does... and then some!!!....
my phone is rock solid dude........ oh and this is with Btooth and GPS always on~... ....4g rapes my battery...

on the stock battery, stock unrooted evo... My phone was unplugged for 24 hours and the battery was still at 34%
I'm sure I could've gotten 30 hours out of it

I use the Sprint Lover's ROM. On days of light use, I usually get a full day out of my battery. Sometimes more.

No 4g on, at home using my own WIFI. Very minimal use Stock battery btw

I would get rid of the Overclocking. Most Kernels out now perform better without it. Also run WiFi when possible and disable all background data sync. Turn GPS off until you need it. Black / Dark background and themes get better battery life.
I have not ran any CM7 ROMs, but seeing how they are all Beta still I don't think it is the best option if you are looking to improve your battery life.
The only non-sense ROM I run regularly is MIUI and I get easily 20 hours out of a single charge (usually have 15% left at 20 hours). The 20 hours consists of probably 1 hour talk time, 50+ SMS messages, light web browsing (less than 1 hour) Facebook browsing, XDA browsing. I rarely play games on my phone, but anyone who does play games regularly on their phone is not getting 30 hours of battery life on a stock battery.
The battery life you say you are getting is definitely too low for what the phone is capable of with your usage. I would try switching ROMs if you have tried everything else and are still getting poor battery life.

There is no "true" definition of "heavy user" so those 30 hour claims should be taken with a grain of salt.
The general consensus of a heavy user should be someone who's Awake Time is more than half of their Up Time.
Most of the people that claim to be a heavy user should be put in the category of moderate or even light user by a generalization standpoint.

I use my phone a lot in a business setting. Emails, calendar, facebook, and web browsing on an hourly basis usually pretty heavy for about 8 hours a day. That said using Caulkin's ROM and the stock battery I would get ~24 hours as long as I didn't play games like Angry Birds.
With the 1700mha replacement battery I can get ~36 hours now.

I find it a lot more accurate to focus on AWAKE time vrs uptime.
I can go 48 hours on a single charge if I don't use it.
I find, on average, I get 4-7 hours of actual AWAKE time, meaning I am actually using my phone, before I dip below 20% Of course, that time will vary depending on what I am doing. Just watching movies, I will get 4.5-5.5 hours.
I leave bt on always and GPS.
Running Fresh 3.5.0.1 with stock kernel.
I think anyone should expect these types of numbers if your battery is calibrated correctly.
Also when testing, make sure to fully FULLY charge your phone. Losing that first Up to 10% will really leave you disappointed.

I get 30+ hours all of the time. Here is how.
I found out that running the stock battery all the way down till the phone turns off, then recharging it all the way a bunch of times kills the life of the battery. As a result if you are having huge battery issues now, either go to a sprint store and see if you can get a new stock battery to start, or go to bby and get one of the 1750mah batteries. It is the same size as the stock battery with a little more juice.
Rom - Fresh 3.5.0.1
PRI - 1.90_003
PRL - 60675
Baseband - 2.15.00.11.19
Kernel Version - 2.6.32.17-gee557fd [email protected] #15
Hardware Version - 0003
This combination alone, Stock fresh, PRI, PRL and Radio i hear is one of the best combo's for Battery.
as far as what i run.
I use Launcher Pro as a launcher, and i have straight Text Icons for my main launcher buttons.
I have absolutly no widgets running except for a clock.
For launcher pro i have 3 homescreens and thats it.
On fresh's notification bar i have GPS turned off, Wifi turned off unless im at home, Blue tooth turned off, Data turned on, and Sound On. Thats it.
I have Enable Mobile Network Always on turned off.
I have landscape turned off.
I use RA_Amon recovery
I use Handcent and Swype, i use Google Voice for voicemail service and i turned off automatic sync'ing
I ran Autostarts to turn off anything that i didnt need to run in the background that didnt look important. (When you run this, the area i modified is the section, Run after startup) Things i turned off were mostly anything that was sprint or HTC services, Facebook, Live Profile etc etc. Play with it, it varies with what you have installed.
Once in a while ill charge to full, turn off the phone, unplug, plug back in till the light turns greeen, Unplug and Plug back in till the light turns green, about 5-10 times. but i do this once every few weeks.
I dont use any task killer or mem manager. froyo does a good enough job of managing its memory.
Hope this helps...

As seen in the graph, i didnt use the phone much, just the 6th day, used it for 5 hours installing apps in the market and draining out the last 20% juice, which could possibly add more than one day and get the full week
I have China Unicom 1.11 (Froyo 2.2.1) *Now i have China Unicom 2.10 (Froyo 2.2.2) Same results.
Edited /system/build.prop and increased value of dalvik.vm.heapsize=42m
setvsel 18-300 30-600 40-800 (Underclock starts at boot to save lots of energy)
Wireless Lan policy set to never sleep (incredible but it actually increases battery life)
With stock dialer to record calls
Removed all screen widgets
I backed up everything system/user apps with titanium backup root
then i use titanium to safely remove system apps and restore some if something fails:
Removed:
VPN Services 2.2.1
Visualization 1.0
Voice Search 2.0.2
TTS Service 2.2.1
Tilemaze
Sudoku

Messenger 6.5.0
Sinaweibo
shop4apps
QQ
News 2.2.1
News and Weather
Mobee
Maps
FOTA
Adservice
Motorola Photowidget
Landlord

I use:
Launcher Pro (instead of stock blur launcher)
OSMonitor to check which apps eats the most; and never install something that i foresee im going to use only twice times a week but starts at boot an run 24/7
BatteryMonitor widget to draw battery graphs
Setvsel to underclock
Gallery++
Rockplayer
Vplayer
Ebuddy + Mercury for msn
Sound Recorders
Colordict
SoundHound
Zedge
Etc.
None of them starts at boot and i dont use task killers,
I did some testing, the more you use the phone the more draining because of the screen 50%, radios are the next, gps, and then cpu.
The best way to afford battery is, you can't save much energy really, but the important is when you have the phone in your pocket in standby state which is most of the day, to get it to drain the less possible. When in pocket you dont need 3g, gps, or some other stuff, turning it off is good, sure there are apps in the market who does this automatically.
In my graphs its 0.5% battery every hour, in standby for 24h it drains 12%.
Other roms drains 1%-2% per hour, that is 24%-48% a day. In standby mode!!
I used barebones for a few days, and it drained 5% per hour in standby!! 5 hours in my pocket = -25% battery! or 100% in one day; I dont blame barebones, i just dont know what happened, what is sure my cpu was limited to 300mhz while screen was off. (setvsel) and i noticed no apps was draining more cpu than they should. but maybe some app avoided "deep sleep state"
1 hour duration call is 10% of battery for me with this rom. if you can minimize the drain while the phone is in the pocket, the best.
I have a theory this is possible because of the deep sleep state in this rom is working a lot better than in others. Deep Sleep = CPU shuts down for a period of time, and when some counter reaches zero (apps set up counters all the time) then cpu is awaken and it does its job.
In a Rom working well, you should get lots of this system messages (you can view then in OSMonitor.
<4>[52286.366027] Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done.
<6>[52286.393585] PM: Resume timer in 42 secs (1402077 ticks at 32768 ticks/sec.)
Widgets and annoying apps who upgrade itself every 60 secs disturbs this sleep and drains more battery.
With barebones 1.5.1 i got no sleep logs at all (i dont know to blame barebones or some rogue app disturbing the phone's deep sleep) if someone notices, please let me know.

Details please
My DEFY in standby takes about 2% battery on hour. This subject is very itresting for me.
Maybe you write some details, which rom you use, what crapy stuff you wipe? What ap. you have instaled and use?

wow 6day of using.by the way could u elaborate more on your daily usage.as my phone can last 3 day (eclair)with minimal use without play or surf.

congrats
My DEFY made it for 3 days... but I'm using it alot so I'm fine with that Had a PalmPre before and the Pres battery last for 8 h with only 2g turned on...

Almost no calls, only alarm is set, i just pick it up when i hear the notification sound for sms or emails, read them fast and i go back to my business. The last day i used it consistently downloading stuff from market and executing apps for 5 hours, to spend that last 20% (i wanted a full charge nextday) so it could have been 7-8 days.
But eclair is not as optimized as Froyo. You should upgrade to gain some more speed / battery life. And i think the most important stuff for battery life is setvsel + wireless + 2g
I first used setvsel long time ago, and noticed 24-48 hours increase between charges, and after the wireless trick, i noticed another + 12-24 hours increase in battery life. (these are aproximations because unfortunely i didn't make any test)

Automatic sync drains alot
I get my DEFY up to 3 days when I'm on roaming cause the automatic sync is deactivated. If not it lasts only 1 day with "similar" using profiles.
Does anybody know if the DEFY switches to 2G when auto sync is deactivated? I use Widgetsoid to do so.
Thanks,
hartmuna

My Defy needs charging every 24 hours - I am a low user.
My sons Defy needs charging TWICE in 24hours - he is a medium to high user.

6 days is pretty impressive but with no to little use kind of defeats the purpose of the phone. Right now, I am using jboogies liquidarc (which is sweet!), I use my phone regularly (phone calls/texting, wifi/internet, gps, games, etc).
I am 84 hours in with 30% left. When I first got the phone before I started flashing custom roms, I'd usually charge every night or at most 1 1/2 days in...now I nearly forget that I actually have to charge the dang thing

Mine has done 25% of the battery in 24 hours, it is a stock SIM free UK Defy running 2.1 and launcher pro rather than the blur launcher.
Usage over the last 24 hours is:
mobile standby 23hours 58 minutes.
phone idle 22 hours 18 minutes.
display 1 hour 39 minutes.
wifi 38 minutes.
I have used it for twitter, facebook and to collect emails over wifi only, the phone is set to 2G only. I cant recall making any calls but i have sent around 100 texts and MMS. Only widget i have running is battery monitor.

I use the app "Timeriffic" to:
-send my phone automatically in flightmode at 11pm
-deactivates flightmode and deactivates sound at 6am
-activate sound at 10am
At 10am I am awake in 99% of the cases. It deactivates flightmode at 6am so I can take a look at the LED when I wake up.
Other possibility to save energy is to deactivate vibration completely.

Very impressive
thanks for sharing
P.s
there used to be a thread where people wrote what's a must in motorola services and what can be uninstalled.

thanks very much，but it's a little unblievable

Why do you think it's "little unbelievable"? I've also managed to obtain 4 days with moderate use (around 10 hours of radio and music listening, 30-45 minutes talk-time). The secret is to undervolt your terminal using SetVsel, to remove the bloatware and set network on 2G.

He got 6 days because he only downloaded stuff in wi-fi. I've done plenty of testing, and what kills the battery is having open mobile data connection (3g more son than 2g). You can get a lot of extra juice from switching 2g/3g and much more by killing the mobile data connection. (widgetsoid switchers will help you with it).
Once I noticed this (I stayed home a whole day and had 90% of battery, thanks to wifi), I was happy to know that my phone was no different to those with super long battery life. That said, I think that as long as it goes for whole day without problems, its fine. And with setcpu and a blurless rom, thats easy to get.
Just find the right balance between battery life and features for you and enjoy your phone!

8 hours flight mode 1%

My Defy is charging every night , max battery life is 36h

With UltraJuice on, after 48 h since unplugged, this morning it still had about 30% of battery. I charged it for like half an hour not to have surprises.
Usage: about 30-40 minutes of talking, 3G with data off (probably 2-3 syncs over the day), about 30 minutes of wireless (syncing), some 30-60 minutes of Angry Birds, etc (maybe a few camera shots, a few USSD requests, looking at the clock, searching in the agenda). Ringer at 100%, vibration on, screen on auto.

Random power drain

Yesterday as I started my day, i pulled my GN from its charger (99%) and made my journey to uni. The trip takes about 50 mins. For the past month now Ive been using poweramp and have had no problems. But when i got to class i realised i had like 25% power during my trip and the back of the GN was a bit warm. I closed all programs and the power drain stopped. I was a bit concerned so a few hours later when i tried playing music again on poweramp but nothing drained the power. So maybe it was a freak occurrence?
So I went to bed last night and the phone was fine. something around 80% power. I woke up 5 hours into my sleep to check on my phone (its a bad habit) and went back to sleep for another 2-3 hours. When i woke up i found my phone had discharged a whole lot of power again randomly in that space of a few hours.
So what the hell happened in that time?! All I did was turn the screen on and turned it off. My usage patterns have not changed.
here is an screen shot of my power usage. You can see the first drop of power, thats nothing of concern as i was playing angry birds space before bed. Then you see the straight line as the phone was idle while i was sleeping. The next drop is when I woke up to check my phone and that's when the discharging happens again. Then you see it recovering when i woke up and closed all the background apps in hope that it would stop the power drain..which it did.

Anyone have some ideas as to what is causing this?
Also keep in mind that before the first instance of power drain my phone configuration had not changed a single bit besides a light flow lite update the night before.
edit: oh FYI, running stock 4.0.2 on yakju

Any apps that you updated or installed yesterday? New rom? Did you make any changes to your phone at all since yesterday?

No new apps, but some app updates. I know at least light flow was updated.
this random power discharge is really getting annoying. It happened again today.
A new symptom seems that the video doesnt load on the phone. for example, trying to load youtube or recorded videos saved on my phone.
Originally i thought my 3g was playing up but when it wouldnt load a video i recorded that was a bit unusual. in fact the gallery app froze and crashed.

Did you search the forum and install CPU Spy and Better Battery stats?
Get some data and find out what is causing wakelocks. Your phone has a lot of "wake" time.
See with CPU spy how much it is spending in Deep sleep and with Better Battery stats look what is preventing it from going into that state. If it's an app: simply remove it.

How's your signal service been lately? I get pretty stank reception at work so my gnex gets pretty warm at the top and battery life suffers. I just put it on airplane mode and reset the radio to force it to chill out for awhile

Thanks ill try that. Just installed CPU spy. Is there an alternative to better battery stats? Don't really want to fork out something to debug this.
I originally used OS monitor, and i checked what was running while the abnormal discharge was happening but nothing showed up.
You make a good point about the amount of wake time though. That long stretch where i was sleeping, my phone shouldnt be waking up that much should it? It didnt seem to affect battery life that much.

Better Battery Stats is the one I use and is recommended here a lot. It gives you insight in the wakelocks from the kernel, as well as from apps. Don't know about the alternatives. It's definately about the wakelocks. Your phone should be in Deep Sleep for 90% or so when you don't touch it (depending on your sync frequency off course).

The only account that is sync'ed is my gmail. The other two listed (twitter and dropbox) is turned off. Are there other options to turn the freq of when the phone syncs?
It's so strange because before these problems came about I had good battery life. ie: 3+hours of screen time.

You usually set it at System Settings, accounts & Synchronisation but some apps allow you to set it within the app... There are apps that allow you to make profiles so that, for instance at night, your device turns off all data. I used to use Juicedefender but that was IMHO more a placebo effect then a real improvement.
I definately think you should install the mentioned apps and after such drain re-appeared analyse what happened.

So after a little bit of troubleshooting I narrowed the problem down to Light Flow Lite.
Last night I went to bed with 100% charge. It discharged normally throughout the night until 4 hours in when I received an email. I woke up about an hour later and saw this so i suspected it was light flow. I cleared the notification and went back to sleep. I woke up about 30 mins later and was sad to see that my fears were confirmed. Battery discharge had settled down and was acting as normal. Just to be 100% sure though, i sent an email to myself to set off a notification and left it for another 30 mins, and as you can guess, the battery started draining excessively again.
Here is the screenshot. First part obviously is when im sleeping. then that dip is the email coming in. That TINY TINY dip upwards is another email coming in a min after I cleared the original email. So the battery drain continues until i wake up and clear it again. This time no more notifications came through and the battery drain settles down.
Again keep in mind that I have used Light Flow Light for 2 months now without problems.
Anyone else experience problems with Light flow or Light Flow light since it was updated on the 20th March?

I have been great with my light flow lite..I had a problem with my own battery when I updated Google chrome.. uninstalling that fixed my problem..

REALLY Poor Battery Life for 80 G9

As much as I love my Archos 80 G9, there's one thing that I truly don't love: the battery life. More accurately, the lack of battery life. Archos' web site boasts 7 hours of video playback, 10 hours of internet surfing, and a whopping 36 hours of music playback on a single charge. My experience is quite different, and I'm currently getting about 5 hours of idle time!!! That's right, just unplugging it from the charger and letting it sit there drains the battery in about 5-6 hours. Now I'm not expecting to be able to watch the "Lord of the Rings" trilogy on a single charge, but just being able to get through "Return of the King" would be a nice start!
I do run the tablet on Surdu's custom ROMs (there are just too many root features that I actually use to go back to stock), but I've had this issue since I bought the tablet back in October just running stock. Even running the "stock + root" ROM (no overclock, fancy transitions, etc.) leaves me with a dead battery in 5 hours. I use a custom Launcher (GO HD for Tablets) and a live background, but neither of these should affect battery life while idle. It could very well be background processes, but this being my first Android device I'm uncertain how to proceed and figure out what might be the problem, or even if I need to send it back to Archos for service. Any help would be appreciated!

the live wallpaper may very much have something to do with it. You need to find a battery stats app and find the rogue app that triggers the device to wake up even when in sleep. Have you tried deep sleep? (in ICS > settings > battery > check "deep sleep"
i usually have a very long battery life while on idle see this screenie

I turned off GPS and Bluetooth, and that has dramatically changed the battery drain for the better. I'm still at 68% after 7 hours at idle with about 10-15 minutes of active use. Still not ideal, but much better. I'll keep trying to find any rogue apps and quell any leeches. Lookout Labs' Ad Network Detector is good at figuring out which "free" apps use the more obnoxious ad networks; it helps to get rid of those, as well.

I'm experiencing same issue here - Archos G9 TURBO 250 HDD with latest ICS and it drains batt while off
Have you found cause of this problem?

a)disable GPS (it's enabled by default)
b)turn on Deep Sleep (settings->battery) or
c)use Hibernation instead of locking the screen only (long press Power and select Hibernation)
If device is powered on and deep sleep/hibernation is not activated it uses quite some power all the time.

a) I turned off GPS but no effect
b) Deep Sleep was turned on from begining
c) tried both hibernation and normal locking the screen - no help
This was on ICS, I'm now trying HC and see if this drains my batt too.
I even installed System Panel Task Manager and enabled monitoring but didn't find any app using too much battery only wierd thing was display - on when I didn't use device...

For me, the GPS was definitely the main culprit. I turned Bluetooth back on and my battery life was still vastly improved, even running overclocked. Beyond that, just keep looking for apps that stay running. A lot of "free" games and apps will keep calling home, even if they've never been launched! MIB3 from Gameloft does this as do many others.

I've installed HC 3.2.80 yesterday, full reset of system and storage, charged to 100% and now only 8% of battery left. I have deep sleep mode turned on, gps off, bluetooth off, tablet switched to airplane mode, in battery usage details - 100% of inactivity (14 hrs 20 min) but something ate my battery. Any ideas?

Did you install any apps after that reset?

[MM] Got Poor Battery Life? No Deep Sleep - Possible reasons, and possible fix inside

Like a lot of people I found myself with battery woes on the G4, at first my battery was comparable to my G3, if not a little bit better but over time, and certainly since MM was released, my battery life was quite frankly awful.
Long Story
I was losing power rapidly, even when I was barely touching the phone - so I finally decided to look into it. After carefully monitoring apps, wakelocks etc nothing looked out of place, everything was working normally until I installed my old faithful app - SetCPU, this is a nice basic app that just shows what your CPU has clocked too and how long it spent there in a given timescale and one thing alarmed me greatly. I was getting less than one minute of deep sleep in every 60 minutes the phone was running - now if I had been using the phone for 58 minutes of that hour I would expect this, only I hadn't!
I did more testing, and more testing and more testing but the results were the same, the phone barely entered deep sleep, and when it did it didn't stay there very long.
Now as I said, using all the other apps, and android stats, nothing looked particularly out of place and after a few days of trying everything under the sun to fix the problem I decided to go nuclear. I wiped the phone, installed no third party apps but setcpu and began testing. I left the phone for a period of 10 minutes to see what the deep sleep value was (looking for it to be somewhere between 80 and 100% of time, which it was!) and it seemed to be back to normal, working fine. So then I started to install my core apps, one by one running the same 10 minute test between each one, idea being eventually I would hit whatever app it was that caused me problems.
So I installed upwards of 30 apps, and everything was still fine, in 10 minutes of not using my phone I was getting around 9 minutes of deep sleep, which is what you would expect.
And then came facebook, now I know there are lots of reports of facebook being a bad app blah blah blah, but I have never seen facebook react like this before, and I don't know if it was marshmallow or a mixture of marshmallow and LG - but when facebook is installed my phone stopped sleeping again, at first it wasn't a huge change, but was noticeable it dropped to deep sleeping at about the 40% mark so I had 4 minutes deep sleep in my 10 minute test - force closing facebook made no difference, I tested it again and again, rebooted and again - same results.
I then installed facebook messenger, and my deep sleep dropped again, to about 20%.
I then uninstalled messenger - no change.
I then rebooted - back to 40%
I then removed facebook - no change
I then rebooted - back to 80+ %.
TLDR: The "Solution"
Now for some of you this won't be a solution as you will claim you need the apps, but there are third party alternatives out there that work pretty well without causing this issue.
Facebook (and facebook messenger) on stock MM builds (at least on the G4) causes the phone to hardly ever enter "deep sleep", this means it is always running a CPU clock, albeit the lowest setting, but it consumes far more power than it needs too especially when the phone is not in use.
After removing them my phone is now sleeping fine and my battery life is back to being very good - lost 4% in the last 8 hours (albeit idle, I was asleep), which is much better than losing 4% an hour that I was before facebook was removed.
Go give it a try, install setcpu, reset the timer close go back to your home screen then leave your phone for 10 minutes then check your deep sleep values, then try it after removing facebook (and rebooting).
Let me know how you get on.

I have used it to disable Facebook services and limit the wakelocks and alarms to every 3600 seconds. Last night I had 5hrs of deep sleep with no interruption whatsoever.

only any use if you have root

So interesting...
Can you do those tests again after disabling the Marshmallow battery optimizing for Facebook app ?

I was having these issues too after upgrading to MM. My battery life was appalling and Facebook was keeping the phone awake for hours at a time. I simply did a full factory reset, and then restored my phone from the most recent backup. My battery life is now excellent, even with Facebook and Messenger installed

There was a wakelock introduced with the new version of facebook about a week ago not sure if it is still relevant. It goes by the name of bugreporting service. Something like that. The same goes with FB messenger. I got pissed off with the official app because of this and got Metal instead

I don't run Facebook (never have) or any messaging other than Hangouts and battery is always great (2-3 days). If you don't need it...uninstall it.
Kindle app was always a great one for running constantly in the background for no reason. So I bought an actual Kindle and didn't use the app.

I totally agree with the OP, I started having the exact issues after I updated to the latest facebook and messenger apps and my phone was entering deep sleep at all. I removed them last night and its much much better now.

My girlfriend's g3 with mm gets this message lots of time

Until a few weeks ago, the Facebook app had a setting where you could choose the sync frequency and I was able to set mine to every 4 hours.
This setting appears to have disappeared now. Could this be the problem?

Nope. It's not the solution. I uninstalled Facebook but am barely getting 2+ hours of screen-on time on v20b.
A Redditor mentioned that some process called 'logd' is eating up resources and killing battery life. I used Terminal Emulator to verify it.
Sent from my LG-H815 using Tapatalk

logd is a separate issue that no one has quite worked out what is causing it - it is to do with error reporting, either from LG or Google apps.

That redditor here. Logd isn't actually logging anything when its CPU usage hits 16% (the problem). You can verify by running logcat in adb shell while watching cpu usage in terminal emulator on phone.
I removed logd by renaming the binary, it's over doubled by SOT from 1-2h to 4+h. As this is my first post on xda I can't link the thread I made on reddit about it -- but you'll find it on /r/lgg4 on the first page ("PSA: How to fix 6.0 / marshmallow logd battery drain (TWRP/root)")
