My friend just bought the Xperia M and he is not very happy with the battery life.
This is his battery stats, should the device be awake 24/7?
He is a very light user.

Is this supposed to be normal, his battery lasts around 1 day and 15 hours without recharging in between.

Does he have stamina mode on?

No... This is not normal. As you can see from this screenshot
the phone is awake only when the screen is on, with a couple of exceptions. You should use Greenify to find out what is keeping the phone awake

No, stamina mode is off, but he does not use mobile data, only wifi.
Although he does have low battery mode and location based wifi turned on.

Last i heard, Greenify was strictly for root users and the non-root functions were extremely limited, my friend is not willing to root the device yet.
Any way to find out what's keeping the device awake all the time?
How much total battery life do you get on one full charge?

He should install it anyway, just to find out what is keeping it awake. I can't really tell you as a use my phone a lot and so charge it every night.

Use stamina mode. I use that and I'm a light user and can easily get 1.5 days or more on battery.

Just instal wakelock detector and chceck what is waking up your phone, then simply uninstall this app... or just reboot phone - sometimes it helps. Stamina mode won't change anything, it only disable data traffic when screen is off.
The phone battery should last for many days with light use and as @Antrikos48 has shown, almost flat line when not in use.
This is an example of an XPERIA C1905 left for a day doing nothing which would mean more than 10 days battery life at that rate. (Installed applications and usage will be different for different people)
I use GSam Battery Monitor to check battery use.
Any process keeping the phone awake can be viewed from the main menu as follows:
App Usage -> View Time held Awake
But for your immediate problem Wakelock Detector-Save Battery as @iks8 has suggested is probably all you need.
If the person using the phone just uses a few applications and is aware of any problem applications(when fix is found), you could also uninstall the battery monitor applications when not needed as they use a VERY small amount of background resources/memory (the very thing you're attempting to eliminate) if they're not being used/viewed often.
Also for a few applications and light use on a non-rooted phone (now you're aware of diagnostic applications) I wouldn't be to concerned about installing battery/application management apps as in a small basic environment there's really not much to manage.
If you manage data/network use effectively yourself Stamina mode may not really provide any real benefits.
One last thing not always considered is if you are in a very poor mobile phone signal area and have 3G/HSDPA data enabled and/or even GSM the phone will use more battery in an attempt to get the best signal it can in the area it finds itself in.
The signal strength indicator ranges from green(best) to a yellow-grey(worst) colour depending on signal strength.
However, as the OP has show, this is not a problem in the location the phone is currently in as signal strength is green(very good).
Greenify's effect on deep sleep seems instantaneous, the device is not awake all the time but its still not as good as its supposed to be.
Also greenify is not showing up several apps, mostly the system apps and preinstalled ones, probably because the device is not rooted, is there anyway to take care of them without root?
Wakelock detector shows now mostly system processes and preinstalled apps causing the problem.
GSam shows screen and google services taking up the most.
I'v had him disable all the packages except for the google services framework.
Plus he has now turned off the location based wifi option just to ensure the phone doesn't takes up any juice while searching for wifi networks during night when the network is itself turned off.
Can you suggest anything else i can do about this?
Sent from my GT-S5830 using Tapatalk
In GSam Battery Monitor, there are additional options that displays the number of times a process wakes the phone up and the percentage battery/resources that processes uses while awake.
This can be found my selecting the options available from the menu at the top of the screen from within the "App Usage" display.
A process may wake the system tens of times(not always a good thing in itself), but there could be a proccess(s) that only wakes the system a couple of times but continue to use resources over a longer period of time.
I have seen the likes of Offficesuite Pro wake only once, but then never ends when attempting to index files in GingerBread 2.3
The processes you have shown would seem about right for JB 4.1.2 as there's not much you can do about Google Services, Kernel or Android OS.
In the old days, having WiFi location (GPS, Access to my Location) active then invited Google Maps to track your location if the option (Google Location Settings) was enabled. This took up a lot of battery resources.
Other things like email "polling" settings could be set to longer time periods. Use push mail when available.
Calendars can also 'poll' or updates/sync regularly too.
Just be aware that people like me on rooted XPERIA M phones, have removed half the apps in /system/app such as facebook, twitter and etc.
On non-rooted phones these applications can be frozen in settings -> Apps to better refine your overall phone environment and thus reflect your usage.
We also have CPU management tools like SetCPU and etc on rooted phones, which allow us to use different governors and IO schedulers and even profiles for when the screen is off.
These are not available in a non-rooted phone, so you will not see the higher levels of refinement available on a rooted phone when using a non-rooted phone.
Even basic things like the settings for brightness of the screen can save/use battery
The following GSMam Battery Monitor figure shows the time applications have held the phone awake and the total percentage of battery they used while phone was held awake.
This figure was take from a phone running GingerBread 2.3, but the concept is the same.
I'v cheked all the options in gsam, it seems only the system apps are now causing all the major wakeups, user apps are fine.
I know of advantages of root, been using a rooted galaxy ace for the past 3 yrs, it still gets me 18hrs battery on medium usage while running a custom 4.2.2 rom.
Well thanks a lot for all your help.

For the past 3 days my battery is dropping at an incredibly fast rate. Even if its idle it will drop about 20 % every half hour with little to no use. I rooted my phone and am now running fresh with kings kernel but no change. I an even dropping in airplane mode. What can it be? I left it at 90% connected to wifi with the sync off and when I woke up 6 hours later it was at 20%. Any solutions?
Sounds like mine, just turning on the screen drops the batter 1-2%.
Hit menu and click on settings. From there, go to About Phone and then to Battery. Note the awake time and turn the screen off for thirty seconds or so. Turn the screen back on and check the awake time again. If it's not within five to ten seconds of the time you noted before you turned the screen off, something is keeping your phone awake, which does a number on the battery.
square parts or system panel might give a better idea of what specifically is draining your battery, or preventing it from sleeping correctly.
It seems fine, about 15 seconds difference. The weird thing is this only started happening about 3 days ago, I rooted yesterday, and its still doing it.
Go for what Fachadick said. Download and install Spare Parts from the Android Market. Go to Battery History and click on the dropdown box where it says "other usage" and click on "partial wake usage". If anything is taking up one of those bars, that's your problem.
If there's nothing notable there, it could be damn near any of your applications. When you root, you lose settings for you apps (depending on how you rooted), so your autosyncs could be going crazy. Might wanna check those.

What he said Rooting won't fix battery issues. Rooting and installing a new ROM is just like reinstalling your OS. It can fix things or not depending on how it is configured. Likewise it won't fix your phone if hardware is bad.
does it drop steadily or just the first 5-10% or so? There is a well documented issue where the trickle charge stops at 100% and then shuts off so the phone actually drains a bit before it kicks in again. When you first unplug it, the reading may drop quickly until it reaches the real level.
Likewise depending on what you have installed and how it is set up, there may be something keeping your phone from sleeping. Check for partial wake use like the previous poster said and that will tell you what process/application is keeping your phone awake and draining battery.
i had this same problem about the battery before i rooted my phone. after i rooted it i got overclock widget and i get through the day with so much more battery left. i make sure my battery is full right before i go to bed, i put it on airplane mode and go to bed wake up around 7 a.m.(my battery is always at 98 when i get up in the morning so 2% in about 8 hrs) and i get home around 8:30 and my battery is at 48%. and no i dont leave it lying around with the screen off. i constantly go on, text, internet etc.
hope it works for you too!
your friend.

I am having this same problem and it started about 2 days ago. I downloaded Spare parts and looked up the partial usage (screenshots attached). I'm not sure what I'm suppose to determine from this. Mail is showing with more fill-in than any other program, when I click on it, I get the details. Can someone help?

It doesn't appear (to me anyway) that you're having any issues with partial wake time. You may have a runaway app draining your battery and cpu - system panel is invaluable for hunting those down. It will show you each running process with exacly how much cpu it's used. It gets even better and gives evenmore detail if you let it monitor your system over time.

There I go, letting my prejudices get ahead of me again, sorry about that. I think in the market it’s called systempanel – one word.
So will the free version pinpoint the problem, or would I need to do the paid version?

to be honest, I'm not sure - I don't remember what kind of detail it gives you in the free version, but the app is so useful to monitor cpu and battery, as well as for hunting down rougue apps, I would recommend the paid version as a "required" app for all rooters.
when you load it up, the default screen is essentially a taskkiller - but more importantly, you can go into settings and have it show ALL processes, and if you select one of the apps or processes from that main screen, it tells you when it was started, how much cpu it used, how much memory its used, and at least in the paid version, a historical graph of cpu usage - so you can see exactly when it used the cpu over the past 2 hours, 8 hours, 1 day, 3 days, or over the past week.

Bluetooth is off, 4g is off (when's cincinnati going live already!??! Just the heart of downtown and the mall)
Wifi is off, and I've been turning off gps now, but i always used to leave it on and made it through the day.
"Cell Standby" is next with 8%, everything else below that.
I kill everything with task manager now and it doesn't seem to help at all.
It is not possible to exaggerate how fast the battery is being drained. It drops by 1-2% each 45 seconds or so. I've done the Charge-for-8-hours-turn-off-charge-trickle-charge-unplug-trickle-charge-unplug-etc thing last night and no help. This is with no widgets installed, no live wallpaper, no music, when for months i can make it through the day with a little pandora, bluetooth while driving, a game or two, internet, maps, and several other apps throughout the day. I've stopped everything but messaging and phone calls and it still drains just as fast.
PLEASE HELP!
I don't know if this applies to anyone in this thread, but after installing a new rom sometimes I forget that the Gtalk/Gchat app resets itself to automatically sign in, and drains the battery while running in the background.
Changing it to not run automatically helps out for me, although I feel that I may have gotten slightly better battery life out of the rooted stock rom than running the King kernel I'm using right now. At least in terms of percentage drop. I never really reset my battery stats or recalibrate after installing a new rom, don't know how much that has an effect on the readings.
This is turning into a deal breaker
Its not latitude, off. Not ANYTHING as it still happens with everything off and all apps killed in task manager.
No background, no live wallpaper (even though i used to have one all day). No music (even though i used to have pandora on a couple hours a day). screen brightness is always low (even though i used to leave it above medium, and would turn it up to high to watch video or a game, and still made it most of the day before).
The phone's battery use thing swears its "Android System" thats taking by far the most, not even cell standby got larger when i unplugged it in the basement where there's no service.
i've turned off everything i could think of, no apps 'auto update' and i've put all syncing and updating and stuff to manual or off that i could find.
I don't think its a faulty battery because it is ridiculously noticeable that something has changed in that ANDROID SYSTEM is now a power hog. Why and what do to?????

Have you pulled the battery lately? Give that a shot.
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
software
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.
angry birds
battery monitor widget
chrome to phone
documents to go
dropbox
evernote
facebook
epicurious

mnote

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.

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:

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!

In the last few days, I have noticed that the process "Android OS" has been using maximum battery life (about 16-35%) and has also been consuming large amounts of data.
The only thing I have done recently is allow the facebook app to upload all pics from my mobile.
Any connection? FYI, I have not added a Samsung account.
Apologies if this has been answered earlier by I did search for it.
what version of android are you running?
what ROM? what kernel?
how long ago did you start to notice this?
is it a constant issue, or does it fix itself after a reboot or something, or with data connection turned off?
do you use google now?
if you are on the jelly bean 4.1.1 version, did you update OTA or odin? just curious, probably not related anyways...
what recovery are you using?
just trying to get some info before i help. many things in the android OS can be directly or indirectly related to each other but still have a side effect on battery life.
16-30% in general has been relatively normal on JB. (Usually between 14-18% is where it settles to)
Keep in mind that unless you are at least halfway through your batt cycle its going to be higher. If you're at 90-95% batt it can be much higher, just due to percentages and battstats being reset.
Not sure why you didn't find anything though, this has been covered a great many times in the past 6 weeks! Did you look at what the top processes are under Android System?

I had installed root66 prerooted JB rom. When I noticed the problem, I installed stock ICS through odin, updated to stock JB then rooted again but the problem continues.
I have been noticing this for about a couple of weeks. Restarting doesnt help but I havent yet tried turning off data. Will try that and let you know.

16-30% in general has been relatively normal on JB. (Usually between 14-18% is where it settles to)
Keep in mind that unless you are at least halfway through your batt cycle its going to be higher. If you're at 90-95% batt it can be much higher, just due to percentages and battstats being reset.
Not sure why you didn't find anything though, this has been covered a great many times in the past 6 weeks! Did you look at what the top processes are under Android System?

Is this something peculiar to JB? I didnt see this in ICS. The top processes currently showing in the battery stats are Android OS: 28%, Voice calls: 17%, Screen: 11%, android system: 8%...
Is there anyway to check exactly which app is using the battery and data which is showing as Android OS?

Odd... mine is usually only around 10%
Mine generally sits between 11-14% depending on use. But it can show 30+ if you check it at certain times.
For example, if you've fully charged the battstats will have reset. If you reboot the phone it will kick off the media scanner which can run for a while (this can also be the cause of it heating up for a short time). So once its complete it will have used a rather sizable chunk of the overall battery use. Since it usually doesn't run again, the percentage will steadily drop as other processes use the battery.
I know we aren't really discussing the media scanner, but I use it as an example that is pretty easy to see if you watch it.
Android system has a lot of processes which are listed under its category so depending on how each person uses their device it can vary a bit. Most screenshots of 'normal' reports that I've seen usually are around 14-18%. For me its lower, but I'm pretty sure I don't use mine the same way others do. There are times though where it can go higher for me, depending on what kinds of stuff I'm messing with or testing out.
I believe transferring large amounts of data over mtp is one thing that can cause it to go up...
Hope that makes sense.

my phone just started this last night. i took it off the charger around 11 last night (100% charged) and it woke me up at 3:30 with a low battery indicator, i checked task manager and nothing was open battery stats showed that android os was at i think 38%. i put it on the charger this morning at around 9 am because it had died fully. it's now 1 pm and it's at 95% charged, typically it takes only a couple hours to charge. my phone is fully stock running jb.

What kernel/ROM and version of recovery are you using?
You can track data consumption of Android system apps via Droidstats
You'll be able to know wether it's Google Maps or any other service that uses data
I am fairly confident I've tracked it down to the touch sounds. Sounds dumb I know, but I believe they are wake locking excessively. I have much better results with ANDROID OS drain with them turned off. Interested to see if others do too.

Hey there,
im having a similar issue with my Google Nexus 10 running stock Android 4.2.2 (fresh install of factory image and then manual update with ota update.zip).
Here are two screenshots (didnt want to include here because they are HUGE and I dont know how to resize them in forum "code"):

I havent been using it much the last days and im a little spoiled by an iPad 2 standby time so this is not very acceptable
I'll try Droidstats and see what I can make out of it.

Looks like you haven't used the tab (screen time) that much over the two days, making Android OS seem overtly guilty.
Try disabling touch sounds -- settings-sounds- touch sounds
Then let us know. I am convinced that is the culprit of the wake locks, keeping the Android OS (kernel & drivers) high and eating battery.

Sorry, forgot to mention it. I have them disabled since i own this tablet (and I checked it again).
I wanted to try DroidStats, but it seems to be an app for calls, sms and data
Can you post a link to this app (if its allowed )
EDIT:
Yesterday a friend of mine showed me the battery stats on his Galaxy S2 and had almost 40% "Android OS".... but he has never had better battery life. I start to think that (because of the percentage system) the built in battery tools are almost useless
Is 4 days a normal standby time for the Nexus 10? That would be very bad in my opinion.
I've just started seeing the same thing with my Galaxy S3 (Samsung issued ICS, rooted). Normally the battery will last around 24 hours with light use, but currently it's draining from full to warning level in about 4 hours with the screen mostly off (wi-fi, bluetooth and GPS are off at the moment). Touch sounds have been set to off from day one.
Yesterday, the culprit looked to be Beautiful Widgets (around 38%) so I turned some of that off (weather update animations, etc) but I'm still getting the same drain speed - now showing Android OS 26%, Cell standby 22%, Android System 15%, Screen 11%. Not sure if I trust the results though, the BW issue from yesterday could have been a red-herring.

[SOLVED!!]
i have this problem with my galaxy grand phone ,the battery discharges in 20hr , default OS was 4.1.2 official samsung , i changed my rom into a slim custom rom based 4.2.2 , but the battery has same problem again , Android OS battery Usage Was 80% !!!! and screen usage just was 9% !
my installed software :
Viber
WeChat
MyKet {Like Android Market}
Weather Widget
i used wifi 1-2 hour in a day ,
=================================
[SOLVE]
first go to Settings -> Developer Options -> Apps Tab -> checked Don't keep activities
set brightness to auto
then go to location services -> off access my location
then go to wifi -> advanced Wi-Fi -> keep wi-fi on during sleep -> change to Never
now go to application manager -> Running Tab -> Force stop some apps with extra ram usage like settings
my phone just uses 5% battery in 13hr sleep mode ; ENJOY!
Hello everyone!
I have a quick question: why do all the reviews talk about 6+ hours of screen on time in "real-life usage conditions" while my M8 only seems to get around half of that? I'm usually down to 10% when my screen on time is 3,5h or somewhere around that depending on what I was using it for. Do these reviewers turn all the connectivity off? Or are they in airplane mode or something? Brightness all the way down? Mine is on wifi almost 100% of the time, google now and location reporting and such enabled. I know I can turn these off to get better battery life, but can you still call it a "smart" phone, if it doesn't even know where you are? It takes away all context awareness applications.
This isn't limited to my M8, I saw this trend on all the phones I've owned, so here's the main question: do I have bad luck and are the batteries in my phones always bad ones? Or am I using them different than those reviewers? (I mostly text, use facebook messenger and browse the web)
Looking forward to hear about your answers!
Note: I know there are a lot of battery life threads, but I thought this would make more sense in it's own thread.
I'm running the latest HTC Stock firmware (5.0.2).

Google Now eats battery for breakfast. Even with syncing all my possible accounts (eMail, Google, WhatsApp, Threema, etc.) and having WiFi or 3G usage lots of times, Google Now (and especially in High accuracy-mode) is still #1 battery consumer. Did you have a look inside your battery usage using some tool like GSAM Battery Monitor?
Yes, i am regularly checking gsam, but the kernel and system apps seem to be eating the battery the most. Screenshot attached.

yes, huge parts of the location service go into the "Android System"-group. Just try setting the location accuracy a bit lower (or disable location services completely), just for one day, and compare the results.

I had good battery life on TMO Stock 4.4.4, but as soon as i went to 5, yeah not good. My battery life seems to be about 40% worse.
So much for Project Volta
Do the custom roms improve battery life?
My batt results are pretty much the same as yours. I have GPS to high accuracy and am usually on LTE (however I did turn off location services as the wakelocks were killing me).
i m getting 4.3 hours screen on time with 1% battery drain per hour on standby... stock lollipop... google services eating battery

Here is the bomb, brace yourselves:
My current setup:
Latest S.ROM (Stock Android 5.02 + Stock Kernel)
No facebook (disabled)
Wi-Fi Scanning Always On: OFF
Location mode: battery saving
No google account
Mobile Data: Always On
Brightness: Auto
Everything else: Default
I get:
7+ hours screen-on time
18 hours of usage, AND
By the end of the day, I still have 10-20% battery leftover.
It turns out Facebook is a battery parasite (, but having a google account is the true mother of all battery hogs. From my own experience, Google Services uses about 35% of my juice. After removing the google account entirely, Google Services use only 5%
Opinion:
Google services are cool, but NOT cool enough to sacrifice both my privacy and a high-quality phone experience to. I now enjoy my phone as much as I please for as long as I'm awake.

nice to know that... by the how much time your charger takes to full charge your phone?? my is taking 2.5 hours from 0 to 100... is that normal? i m using stock 1.5 A charger.. wht about u?
I honestly have no idea, but, "Overnight" should accurately account for that. It's terrible, I know.
Cheers
@shirreer how did you remove google account. Is it by disabling google services?
To remove a Google Account:
Settings -> Accounts and Sync -> Google
Tap the 3-dots menu next to your name, select remove.
You might also want to clear the data for Google+, Google Now, and Google Play Services (must deactivate ADM first).
Good luck.
everyday i got 18 hours 5 hours sot. if i use more lte during the day the sot go down to 4 hours, but i always use high brightness with auto enabled, sync activated and location on battery saver.
My phone usually charges in around 1hr30min from 5 to 100 (although Im using a 2amp charger). So seems about right. I am running stock Lollipop from the GPE (5.1). Usually I am getting around 4hrs sot. I do have Google services enabled as I do use them often and screen brightness at around 45%. The only app i have greenified is FB.
Overnight Im draining due to Nlp wakelock. Anybody experience this?
I was trying to locate a thread on a serious battery drain ptoblem caused by Android OS wakelock, could not find any references

I have tried doing partition wipe cache and disabled most apps under auto start manager, unable to figure out what is causing this issue
I have no other issues on Asus Zenfone 2 and it is probably the best Android phone I have ever used, just this battery drain issues is irritating.
Lot of Zenfone 2 users have logged this issue on Zentalk forum but Asus support seems to be clueless about it, recent firmware update also failed to address this problem.

I think it depends on wi fi...
When I'm at work ZenFone connect to various AP and the battery drain is heavy....
But when I'm at home the battery seems to be normal, I can finish the day with 20% of battery from 17 to 21.
I see the battery is longer on 3g/4g than when i'm at work on wi fi
I think Zen Motion in settings specially touch gesture is one of the causes for battery drain issue...

Probably...but when I'm on 2.17 I don't see this battery drain....and I always have gesture, double tap to wake/sleep and zenmotion all gesture.
I see the battery drain increased when Asus have changed power profile
'Wifi Scanning always available' may cause battery drain. Recommend to turn off in not needed. To do this go to Apps/Settings/WiFi Settings/Advance Settings(menu in upper right corner)/Scanning always available/ turn Off. If battery still draining, recommend updating firmware to latest version and then performing a factory data reset. Please ensure to back up all important data as this will erase all data.

Hi Frank,
Regarding the Wi-Fi always on thing... Whenever I turn it off of always turns back on automatically.... Any advice.. I already am on 2.19 BTW..
Apologize for the delayed response. Strange, it shouldn't turn back on automatically. After latest firmware is applied, recommend doing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

Frank have you heard any rumors on if asus is working on the 5.1.1 update. The issue of Android us chewing up battery is a widely known issue for lollipop 5.0 and it impacts many different devices. Every thread I have read regarding this specific issue states that lollipop 5.1.1 resolves this issue.

My battery stats still reporting WiFi use when I have turned WiFi off and disabled always scanning. I don't get it!?
Edit: just figured this mystery out. It's because I had location set to high accuracy. If you set it to high accuracy or battery saving it scans WiFi even when WiFi is off. Put location to GPS only for the last ten minutes and voilà - no WiFi use in the battery stats
Spoke to soon, WiFi came back again on battery stats!???

Do you see any major results with that application?
I read a lot about awful battery and screen on time before buying the zenfone 2. Surprisingly though with a bit of tweaking this has been one of the best phones I've owned in terms of battery life. I could have easily gotten 10 hours of screen on time i believe if I stayed in an area with stronger reception and turned off some background services like GPS. Here's some screenshots for anyone interested

hmm, Well for screen on time Underclocking should help the most. If you don't do any heavy gaming you can set it down to 1.8 without noticing a performance hit ( you could probably take it down to 1.5ghz but I haven't tested that thoroughly so there could be an impact). I use noop as the I/O scheduler but that probably doesn't make a difference. I don't use greenify but I do use servicely. I also stay far away from facebook and the messenger app as that has always caused me crazy battery drain but I know those are apps alot of people would rather not delete so its up to you. I use balance mode in power saver and also use Asus' built in auto start manager to disable most things at boot I don't need. Another thing that helps with wakelocks is to make sure you open the google settings app after you boot ( you dont have to do anything, just open and close. I don't get it either) it works for many people including myself.
Other then that I can't think of much else I do. If anything else comes to me ill be sure to let you guys know
