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...

[Q] Battery life - Stock, CM7, Pays

Hi there,
So I'd my Defy for a little over 2 months now and I have used the mentioned ROMs with it for at least a week each. It first had Eclair, I promptly changed that to a Pays version of Froyo and now i'm using Quarx CM7.
A lot of my friends have this phone and report battery life of over 24h. They do work in places where they can connect their phones to their laptops and car charger, and they are lighter users than me.
But I'm a med student so I get out in the morning around 6 am, unplug my phone and go to the hospital returning home around 8pm. 14h later my phone is already at 33% charge. I keep wifi turned off, 3G off and use my phone to check MedScape(a medical info repository) and e-mail/facebook 6 times a day and listen to music for 4h.
Is that a good battery life? i mean, for a new phone. I imagine that if I let my 3G i won't get to the middle of my afternoon without needing to recharge.
Around the forum I read about people with OVER 48h of battery life, HOW?
thanks in advance.
Also, as I know it will be asked. My signal reception is flawless all through my working environment.

The .sbf you flashed (for the kernel) is apparently a big factor in batterylife, which did you use under cm7 ?
Which version of cm7 are you running?
Also are you using setvsel?
My settings are 300/23, 600/33, 800/43, and i have gotten almost 5 days battery use on a single charge, with
-texting for atleast 48hr time, intervals of short(10min) periods as you would expect
-maybe 20 mins phoning
-wifi on for half the time when i forget it overnight etc(my profile disables wifi on screen off however-good for light, but battery drain if you lock phone a lot)
-Get the following: OSmonitor, Battery monitor widget.
These help to track what apps eat battery, and kill processes with minimal(1%) drain, that if you arent using then you may aswell take all the battery back that you can
What are your display settings? eg auto brightness, renderfx etc
Thanks

I'm using the latest CM7 by quarx 5.1 and for base i'm currently using 3.4.2-177 nordic Blurless.
I wasn't currently using any undervolting settings to make a baseline screening of the phone with CM7 but i'll try yours and install the apps you've mentioned.
i'm using auto-brightness because of the bugs involved in disabling them in CM7 5.1. And haven't messed with renderfx so far.

Ok firstly i have only tested on 4.0, 4.1 and 5.0 so these suggestions are very likely to work but if certain settings are different in 5.1 then they may negatively affect you- just a thought
Undervolting is actually incredible on cm7 and works a charm, its still super responsive and load times are still less than that of any 2.2 i have tested WITH overclock
Start on about 300/600/800, 30/45/50 and go down marginally-different phones may have different yields to this due to apps running, previous cpu stress etc
(Remember to untick 'start on boot')
Also, the medical database you mentioned- does it contain any 3d renders etc?
This may require you to raise the voltage a little to keep it stable for anything you may to run aswell-- all the apps i have tested such as angry birds, 3d racer games work perfectly btw
Ok, there are extra options that allow you to further change the auto brightness inside the CMsettings under >Display>Automatic backlight
You might wish to experiment if you have time (decrease sensor check-times, lower overall brightness etc), however it likely isnt worth pursuing as the new Quarx beta shows brightness fixes in the changelog already, so just wait is my advice if you are short of time
Ooh and renderfx seemed to drain my battery more on any of the n1 settings, however it may be mix/match to get it right

Hum, I've had bad experiences with undervolting in 2.2 but I'll be sure to try it.
As far as medscape goes, it's just text, no image whatsoever it's just a big list with descriptions "acetaminophen - what does it do, how, dosages and stuff" really useful though
will post back when I have more info from the apps you've mentioned. So far I had used watchdog and it hasn't barked at any of my apps

As long as you take it slowly, undervolting is no problem- also try and minimize the amount of useless apps you have, since many of them run in the background by default without a way to exit them, meaning you constantly waste resources on them and thereby limit the amount of UC/V'ing you could acheive.
Ok thats cool, i was just curious as you clearly need/use that app often
Alrighty then, hopefully you can get some better battery life out of it -good luck

i don't actually have that many apps installed
3g watchdog, only on when 3g is.

well, not that I've written it out, they are quite a few.

He probably means you should use something to kill useless apps running in the background. Look for Advanced Task Killer at the market and install it so you can kill apps that are running in the background but that you're not using.

@Behemia 5 days is awesome in my experience, and you are using your device the same way I am
could you please tell us which kernel are you using (savaged Zen maybe?) and which baseband (if you changed it)?
thanks!

im using cm7 with 3.4.3-11 kernel, undervolted to 300/18-600/30-800/45, kill apps with es task manager quite a lot, 3g or wifi is constantly on, and brightness is set to medium (for some reason auto brightness doesnt relly work for me), and i still cant get one day out of it. battery calibration helped a bit though (i recommend that app to everybody having battery life issues!). is that normal?

Report
So, I've done some of the changes proposed. Undervolted to 300/28 600/41 800/47. Installed Battery monitor Widget, OSmonitor left the phone with 3g off and wifi off when not in use(most of the time) and right now I've got 1% of battery left. That's 1d09h30min after unplug.
Below are the times in ms from the applications that I've used according to battery monitor widgets.
sms 814409
facebook 518805
contacts 355178
dialer 212996
gmail 195103

And here battery use report according to system
display 21%
phone idle 18%
stanby 17%
voice calls 15%
OS 7%
media 4%
winamp 4%
gmail 3%
facebook 2%
I'm not saying that 33h isn't good. But my use in this time has been way below my average for myself and the way below most of what I see described here. Plus I don't see any bloatware running nor I do see my apps hogging my battery. Facebook and Gmail push notifications are set to occurs over 2h apart.
Any ideas?
Also, as I finish this thread the phone finally vibrates and dies. Let's put it back to charge and look for more ideas.
thanks in advance everyone.

@lionheartpl
which kind of sim card do you own? i mean an old 64k or a brand new 128k? i upgraded mine from 64 to 128 due to a mobile operator change and my battery usage (same mod, same apps, same usage, same baseband) dropped from 2-3% hour usage to 1% in more than 1 hour. So battery usage has dropped a lot...

Running stock UK 2.1 i could get 4 days standby if i was just texting and a few calls. with the stock UK 2.2 undervolted to 300/22 600/32 1000/52 i can get 5 days easily but i cant see the point in it cos you dare not really use it, i would rather drop down to 1 or 2 days and give it some usage.

Hello everyone,
I'm getting a very good perfomance with the barebones froyo 1.5.6, check this behavior at night:

That's like 2% loss in almost 8 hours!!!
Right now I am using the version 1.5.1 because I was told it has a better perfomance than the 1.5.6. I'll post my results in a few days.
Also, I use my Defy to be connected to windows messenger network all the time. I'm trying a strategy in order to not drain battery so much:

Check it out

Even i m not getting a good battery life on CM7 RC1 V1, latest Nightly(9th Aug)
using base band switcher as i m from India
i lost around 18 to 20% every night between 12 to 8am.
over with minimum usage i can get 24 hrs thats witout any music and games, call for 30 mins
not sure what to do
some one please help

I can get about 2 days out of a charge. I am using 300/35 700/42 1000/50 and have had no problems. I recommend using battery calibration! A trick that I have learned is to let it charge to 100% do a battery calibration and then leave it plugged in for a while (30 mins). I have my wifi on all the time and run the smartass profile in settings.
good luck!

Is anyone draining at 1% per hour in sleep mode & how are you doing it?

Is anyone draining at 1% per hour in sleep mode & how are you doing it?
I've read some folks draining at less than 1% per hour sleeping. I'd be happy if I can achieve 1% per hour sleeping.
Anyone getting this or better? If so, share with us your secret!
Here's what my phone is like:
LTE version
Kang, milestone 3
Franco 16.2
max 1000, min 350
no undervolt
no solo cpu mod when sleeping
wifi off
gps on
bt on
My best performance is about 1.5% when sleeping. I charged up my phone to 100% and then unplugged it and let it sleep overnight. 7hr:45min later, woke up and it's at 88%.
I did wipe battery stats when switching ROMs, so it's fresh.

I unplugged my phone last night (100% charge) and 8 hours later this morning it was at 94%. So a little under 1% per hour.
Using stock Android 4.0.2 GSM. Wifi was on, Bluetooth off, GPS on, Sync on. Sadly no secrets to share, been pretty happy with the battery life though.

I have stock 4.0.2 and i get even lower numbers than that.. last night i charged it up to 100% and when i woke up (8 hours later) it was down to 96%.
(gsm)

where did you get the franco 16.2?? ^^

I lose about 0.5% per hour in idle. After 8 hours, I have about 96-95% battery left. This is the GSM nexus with the official 2000 mAh extended battery. Not sure if you have GSM or LTE.
Kang, milestone 3
Imoseyon's Leankernel 1.7.4
max 1200, min 350
stock undervolt that is on the kernel
Interactive X governor
wifi off
gps on
bt on
I get around 4 hours of screen on time.

Make sure anything you have syncing is doing it at a moderate level, when I set up my two email accounts they were set to push and sync every 15 minutes, both are way too much for what I need email for so I set them both to an hour.
Also, changed twitter to only manually sync being that it only takes a couple seconds to due and saves the phone from unnecessarily turning on from sleep.
Don't know if this helps but maybe try turning NFC on if you don't use it?
Disable Facebook contact sync as it doesn't work with 4.0 anyways.
If you can, disable bluetooth, same goes with GPS/Location services.
If you have fancy widgets/beautiful widgets, see how often they update location/weather.
Sorry if it seems like every other point here is just checking what is syncing and what not but when your phone is sleeping those are really the only things that will effect battery life.
Edit: Wiping battery stats has been proven to not do... Well anything.

same with me ... using stock 4.0.2 ... drain is about 1% per 2 hours

I drain 1% every 2-3 hours. So after 8 hours i'm at 96% overnight. This phone has superb idle drain. This is with wifi connected, 2 gmail accounts synced, 1 calendar, contacts and picasa, gps is on. But i do not have facebook app installed. I am stock 4.0.1 and dont have many apps installed, only what i use.

mine is great when idle but as soon as I start using it it drops precipitously any ideas or fixes?

Sadly, lower the screen resolution is probably the easiest way that will notch the best gain in battery life. These screens require a lot of power especially at their brightest settings.

Sign out of latitude...
so key to good battery life

I have the GSM Galaxy Nexus running stock 4.0.1 and I consistently lose 4-5% in 6-8 hours overnight with...
- WIFI on
- 3g/4g on
- GPS on
- bluetooth off
- NFC off
- syncing 2 emails, 2 calendars
- lightflow running LED notification for max 2 hour but on silent (not uncommon for a couple of notification go off during the night)
- beautiful widgets with 1 hour sync
- no effort taken to kill facebook or other backgroung apps.

Try out the new 4.0.4. You're standby drain will go down considerably.

OP, are you on a GSM or CDMA Nexus? Are you on 3G only or LTE/3G?

Yep. That's about the same exact thing I get on a day-to-day basis with the same settings you mentioned. In addition, I don't think I've ever turned NFC off. So pretty much everything but Bluetooth stays on for me overnight.

Sounds like you may have a wakelock check your awake time com paired to your screen on time , if its considerably more then you may have some apps waking your device. For me it was Google maps so I disabled it for now till the update. I used betterbatterystas to find the wakelock. Now I get 3.5 hours screen on time and under 1% drain per hour

you guys realized that gps and bluetooth do not drain battery unless you are using them so it doesnt matter if they are on. GPS will only turn on when an app needs a lock and bluetooth wont use power unless its transmitting to another device. im not sure about NFC but i would think it works the same way. as long as you dont have anything syncing or losing reception at night then you should only lose about 5 percent in 7-8 hours. this is the case with most android devices that i've own.

best I have got is 2% loss in 7 hours...

Bluetooth searches for devices like Wi-Fi searches for access points. You kinda missed that...

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?

Yet another LG G3 awful battery duration thread

I'm having a slight problem.. How long can your G3 stay away from the charger? And with which kind of usage?
Mine is dead after 8~10 hours with absolutely light usage (1:30 sot, checking whatsapp, but not even responding the groups, no facebook usage). Every time I turn the phone on, BBS complains about 30~50% awake time, but when I open it up, I can't for the love of God find what the heck is causing it.
Example, it says phone was with the screen off for 30 minutes, with 50% awake. And every single option (but kernel wakelocks) shows apps with about 2, 3 minutes total wakelock time.
When I first bought it, I rooted it right away and restored my TitaniumBackup, and the phone was getting hot on my pocket. I mean, HOT. Battery couldn't get past 6 hours with the usage I had on my G2, and phone was unconfortable to handle and make a call.
And about that, it seems that the battery drains slower during calls, rather than the phone idling.
I started using Greenify and added every possible app to it, but it didn't help anything.
What may be my problem? How can I find what is causing such wakelocks?
Those pictures have been taken few hours ago, when I posted it on G+, and the screen on time represents 1:05hrs.
It hit 15% with 11:53hr total with 1:50h screen on time. Estimated recharge time is around 6 hours. It sucks

Flash a new Rom...like cloudy or something that works for your phone, but don't restore apps and data with titanium bu.
Don't restore android home or anything like that either....just restore apps....then you should be ok.
You battery useage is not normal, but this should fix it.
Cheers!

I'm using CloudyG3. I feel like it was good at the beginning, but gotten worse with time.
I'm seriously thinking about flashing it fresh and not restoring anything, letting Google do its stuff.

That should work....you probably restored an appnsetting that doesn't like the Rom....that's hard to troubleshoot and easier to re flash and start from scratch

Did it. Yet no solution.
I always get 45% phone awake, on BBS. The culprit seems to be Google Play Services. I've tried greenifiying a thousand of apps, but it doesn't seem to help.
http://imgur.com/a/8QCdG
It seems to be related to location services, but I've never had such problem in my life, and G3 GPS is pretty quick to get a lock on. Phone is also getting lukewarm on my pocket for no apparent reason (warm enough to notice it in pocket, at random moments)

That's still not normal.....not sure what to say. Maybe there is hardware failure. Sorry I can't be of more assistance....that should have solved it, but if it's Google play services, you can't even attribute it to a rogue 3rd party app.

Greenified Google Play Services..
http://imgur.com/ildhKIG
So, it IS a Google Play Services problem, but what is causing it? Also, how bad is to have GPlay Services greenified?

I get a 0.4% or less drop each hour that I have no screen time and I'm in wifi (with 2 gmail and 1 exchange accounts syncing/push notifications). I can easily go over two days on a single battery charge with perhaps 30 min of screen time. That is pretty typical from what I've read. Something is wrong with your phone/apps if you are getting well less than that.

Still working on that. A full day without a charge is more than enough for me.
Google Play Services finally got out from the top 3 battery sippers, but I don't know at what cost. It's greenified.
The top 5 currently is:
Screen (29% - 1:14 sot)
Android Operating System (14% - 16m 48s Total CPU, execution time 2h 2m)
Android System (12% - 29m 15s Total CPU, 11m 43s execution time)
Google Play Services (7% - 3m 8s Total CPU, 23m 11s execution time, 1m 59s GPS)
Inactive Phone (4% - Time in use 5h 48m 29s)
Phone was supposed to be dead by now. It still has 66% left, with 19hrs remaining. That is a -HUGE- improvement.
Usage is nowhere near I had with the G2 (1:14hr sot), but it now gives margin to use it more intensively. Hope it stays cool and economic like that tomorrow, when I'll start using it as a normal smartphone to me.

This is caused by Google tracking you. You should disable location reporting and if possible network location service (GPS only). I have a Tasker profile that enables and disables network location with screen. I get about 3%/hr with pretty moderate/heavy usage.

That isn't a option for me. I've successfuly recovered my last G2 4 times from robbers using tracking tools. I can't disable GPS.
I hear GPS only gets activated when necessary, so that doesn't seem to be a big deal. There are some useless trackings, sure, such as to show where I parked my car and stuff.
I'll try disabling Location Reporting and see if I can track it back.
----------
Looks like I can! But Google Play Services consumption is already low. The "problem" now is on the screen (unsolveable, I think. And I ain't downsampling it to 1080p) and Android System/Android OS.
Waiting for the Lollipop miracle, I guess.

Heck, I have yet to go below 5 hours of screen on time with CloudyG3 1.0.. Its been 5 days, and on the first two days i got 6 hours sot.
And thats not 6 sot/6 uptime, it went 20+ hours of uptime(off charger), with that amount of screen on.
I greenified a bit, am on art, and i'm not gonna lir to you, i tend to decrease my brightness lately, why?
Because i don't want a flashlight to my face in a dimmed room, and I can still perfectly percieve everything thats on my screen even with it not being 100% at all times..

Here are my most recent screenshots.
Can't say I'm happy with deep sleep "drain", but oh well, its not that bad...

It seemingly was Google Play Services that were draining the battery like mad. I'm using CloudyG3 1.1.
I had WLD already, and CPU wakelocks were little, if I remember well. Problem was on "Wakeup Triggers".
Sunday's a slow day, and the phone was pretty much the whole time on the wireless craddle, thus keeping charge at 100%. But the moments I took it off the charger and used it for a while on the living room, it seemed OK.
I've let it off the charger during the night to see how it would fare, and it dropped 10% in 9 hours, with virtually no screen on time (I checked the clock sometimes. Bet it doesn't even sums 20 second screen on time). It's nowhere near the 0,6%/h people claim, but I think I'm a pretty heavy user (4G, wifi, bluetooth all the time, no notifications disabled etc).
Funny that the G3 seems to take a while to drop from 100%, though.
Tomorrow's a full day, I leave in the morning and only get back home at 22hrs, with heavy usage. Phone was previously dying on me @ 14hrs.
If it works, it'll be nice. Weird that I've never had a issue with Google Play Services, and it seems that greenifying it did the trick.

disable location because play services checks it as mad or download xposed module lion tamer(donation) and set when it can check (in seconds) I am guessing that the nlp.... wakelock is the biggest in google play services:laugh:

lg are optimizing this in the new versions,
I think a lot of screen

I made a day through! Yeaaaahhhh
Not with some issues, though. This phone seems to be a bit wakelock happy.
First, it was Pushbullet that seemed to be stuck doing something. Greenified it and it's OK now.
But now it seems to be some issue with "com.android.internal.telephony.ACTION_CHECK_NETSTAT".

Is it the fast dormancy thing people talk about? The signal wasn't very strong today, but is it supposed to do a wakelock?

battery issue with lg g3
hi just got my Lg G3 the battery lasted me approx 12 hours with moderate usage and full screen display.
i installed juice defender and kept the screen display on auto.
i believe by doing that the battery drain will not be much.
my phone battery drain is only 4% in the past 3 hours.
try this solution

This is what I did along with using greenify to stop the wakelocks. Haven't had any issue at all with battery or deep sleep after this.
