Stop wifi drain on standbyI - LG V20 Guides, News, & Discussion

I just got an LG V20 which is good on battery when in use but sucks when not in use. The culprit is always wifi. I just discovered the root cause is Location services that is using wifi to get locations even when wifi is off.
To stop this, go to settings->location->scanning.
Uncheck wifi scanning. For good measure, uncheck bluetooth scanning.
Go to wifi menu ->advanced-> keep wifi on when screen is off
Change to never or "only when plugged in"

Hi,
thanks for your helpful tips..
So out of the 3 tips you have:
1. Uncheck wifi scanning
2. Uncheck bluetooth scanning
3. Turn wifi off when screen is off
Any idea how much does each option save (if you've quantified)?
I'm happy to follow points 1 and 2. I'd only do 3 if it really helps a lot, because most apps would use data if wifi isn't available to periodically phone home.

I have always been dissappointed with my V20 standby time.. I had all of these settings on.. so i'll see how she does now they are off.
Thanks!

My standby time is from 0-4% over 8-9hrs. I really cant complain.... but the phone is facing down.

I wasn't aware of the wifi location scanning, and the bluetooth scanning. Giving it a try as my standby time has been horrible lately.

I am also facing severe battery drain on my LG V20. Battery easily drains by 5-10% per hour even when the phone is lying idle with screen off. Major culprits are 'Phone Idle', 'Android System' and 'Android OS'.

As a side note, I've found that using wifi and cell data to help location services causes maps to scan these options and slow down (maps keeps saying every 5 to 15 seconds "searching"). By using gps only, the maps app is faster and less battery drain.
Obviously if you are indoors you need the help of wifi or cell data. But in the car or outside it is unnessary.

Thanks for your tips it's very good for my life battery. :good:

I tried as suggested in the post you shared. Once the Bugreport was generated, I got a notification to click it to share. But, upon clicking nothing happened. I did not get anything (no pop-up, no options) further to share it. I tried thrice but, every time same end result.
How can I access the Bugreports generated on the phone?

Ah, seems like the obvious question but you can't.
I've found the most reliable way is to email them and then download them

- see the cpu running, userspace wakelock & screen on lines. They seem to match. Screen is on, cpu working with userspace wakelock. Close to 7pm the screen is off but the cpu is running, because you were listening to audio. I don't see a problem here. Looks normal
- you screen off discharge rate is 2.56%/h which seems a bit high. If you were streaming audio this might add to it. Do you have the second screen on when the main screen is off ?
- somewhere around 12pm you are using data for about an hour. Mobile Signal strength isn't very good, mostly yellow. What i don't understand is why your wifi is also on ? and this is in an area where wifi signal is bad. Both of these will add to drain. And in two hours your battery dropped from 70 to 40
- little after 1pm you're on wifi for a couple of hours but the signal is weak
- around 5pm you're back on data streaming audio and battery takes a nose dive here. Down 30% in like an hour. Were you moving ?
- then you charge up to 85%, doze kicks in which is good, if there was app drain doze would not come on, for the next 5h without use, you lose about 5%
- the part i don't understand is between 1am & 6am, battery drops 10% yet full doze (blue) is on. So there is some activity going on there. What ? sync ? updates ?
Not sure about the aggregated stats as you've recharged up and run down fr a second cycle so it could be your off screen drain is twice as high because of that
charge up again, go through your day and save log when you're at 5% and lets see the two screenshots from just one charge cycle

Thanks a lot! Please find my answers in sequence.
- I listen to music while going to work. But, that is, till 8:30 AM only. Yes, I have 2nd screen ON when the Main display is OFF.
- I watch stored videos during lunch (12-1pm) for around an hour but it shouldn't be using data as I am playing stored videos.
- Around 5 pm, I leave for home. Again while going home I listen to music for half an hour.
- I have no Idea of what is happening during Night because I just leave it and don't use it until morning. In fact, I have scheduled the 2nd screen to be off between 11 pm and 6 am
I will try to run a proper cycle as you have suggested and will recapture the logs.
I understand the battery dropping while I am using the phone (listening to music/watching videos/browsing/anything else). What I don't get is the battery dropping insanely when I am not using it. For example, once I reach the office, I stop the music, kill the music player and just keep the phone aside. After 1-2 hours, as I check my phone I find battery dropped by 10% or so! It's the battery drain while my phone is just lying idle that is troubling.
Also, I have noticed that once I charge my phone and then leave it (Not using it) the battery drain is minimal like 1% per hour. But, once I run some app (music/browsing etc) for a little while and then leave the phone, the idle battery drain is pretty high.

Same sequence
- When you have the second screen on, is the phone facing up or down. What i notice with that second screen is it ignores any brightness settings. If the phone is face up and pointed at a light, the second screen becomes very bright. If its facing away from the light then it dims. Depending on how your phone faces you will either have more or less drain here, without doing anything and phone just sitting there. Typical overhead with second screen on and normal brightness ie not too bright is around 1% per hour. This could be adding to your off screen drain. Why not try a couple of cycles. One with second screen off and another with second screen on. Just to see how your off screen drain rate is like.
You say you listen to music only upto 8:30AM, take a look at the audio line. Can you see audio triggering ? there's little blips there after 8:30AM which continues till 5:30PM where its solid. This is your ride back where you listen for an hour. The 5:30 audio is ok but the blips in between are not leaving aside lunch video. Each time there is an audio blip there is a wakelock. Pay attention to the duration of the audio blip, if its a few seconds it could just be notification, but if its longer, does it correspond to your use.
Now look at the top app line, try to find which apps are running when audio triggers. To do that hover over the top app line which coincides with audio when you were not listening to audio. You will see a popup screen with a list of apps. Or check History Stats - TopApplicationSummary for a table, screen shot that and post
Do you use a lot of widgets that update in the background ?
- something was using mobile data when you were watching stored videos at lunch. Take a look at the'mobile radio active' line and you see activity there around lunch. Your wifi however is off and not running. If there were any apps running they were using mobile data, this is extra drain
- take a look at the line that says 'foreground process'. it's pretty solid right through both your runs. The only time it stops is when you recharge. This is a hint something is up. If you hover above it what does the popup say ? try moving along the line and observe whether the information changes
There shouldn't a foreground process running when you're not using the phone. Maybe if you can screen shot, the table that displays under History Stats - Foreground Process Summary
Scroll down and under the graph and on the left you will see three headers with twisties, System stats, History stats & App Stats
Hold on to your bug report files and they will be useful to verify if any changes you make take effect or not
- 1% per hour corresponds to second screen on, with it off your drain would be halved. However having drain after leaving a music or browsing app isn't good. It means a wakelock was caused and its not releasing so doze can't kick in. So battery will drain. If the phone is shaking, say in your pocket as you walk around, full doze won't kick in either
Which social media apps do you use.
Stock launcher or other if so which

I've found just buying a new battery off of ebay for $10 is the the easiest way to gain back that extra hour of on screen time and extend stand by. That's why the phone was made with a removable battery. I have 3 of them and don't need to touch a charger for a week. and when the time comes to charge the batteries, just put them in the charging docks and done.

7 hrs of Standby = 33% of Battery?!?!

Okay so I noticed my Captivate seems to lose a lot of battery while in standby. To test this, I left it unplugged when I went to bed last night. I checked the battery level right when I went to sleep and then again when I woke up...
My battery drained from 64% to 31% in about 7 hours!!!
I know other threads discuss bad battery life. A bright screen and a 1GHZ processor can cause this so I can understand why the phone won't allow me to browse the web for 10 hours straight. But is everyone else getting an almost 5%/hour drain in battery while in standby?
Here is a little info about my setup:
-I took off an animated background and put one that is relatively dark (Screen is off during standby so I would think this doesn't matter)
-I have WiFi and Bluetooth enabled.
-I use both wireless networks and GPS for location.
-I have 1 Gmail account setup to check every hour.
-I have the Daily Briefing set up to check every 3 hours.
-I have the Slickdeals widget set to check every 2 hours.
-I have the Latitude widget running (you can't set how often it refreshes).
-I have the ESPN ScoreCenter widget running.
That's about all I did that I can think of that can possibly affect battery. I know I would get better battery with less background widgets, but all of this is in line with the amount of background services I had running on my last phone (Tilt 2) and that thing would last for several days with light use.
So, what I'm trying to find out is whether or not this is normal behavior that everyone is seeing or perhaps if one of the background widgets I'm using is known for draining a crazy amount of battery. Maybe I need to hard reset the phone? Thanks in advance for any ideas on how to lock this down.
In poor reception I could see that. But I'm good area that's too much. Like 2% every hour is good... 5 is too much....
Thanks for your reply. I had 3 bars of service where I was last night. Also, this isn't the first time I've noticed about 5%/hour for standby, just one example...
So it sounds like I'm getting worse drain than normal? Now, how to fix it?
Well...with all the email checks and having various Widgets check for updates..it will definitely drain the battery. I have been able to easily get twelve+ hours on standby without GPS on and turning off wifi when not at home or in a place with wifi.
Definitely can't go days without charging like I could with previous phones like my blackjack II buy I can get 12-16 hours with light to moderate use and 10-12 with somewhat moderate use of Facebook, wifi, various other apps.
EDIT: the Bluetooth as well will drain the battery.
Sent from my SAMSUNG-SGH-I897 using XDA App
I have very similar battery usage to use. About 5% an hour not doing anything. I am always around a wifi and leave it turned on. I have nearly an out of the box setup. Between the poor battery life and crappy GPS, I may very well be taking this thing back.
Under Settings > Wireless and Network > Wi-Fi settings > Bring up the Advanced menu and set the Wi-Fi sleep policy to "Never".
This has helped my battery life immensely, since I am around Wi-Fi most of the time. This way all your data happens over Wi-Fi instead of 3G when the screen sleeps. I disable Wi-Fi when I'm not around any APs I normally connect to.
Pulled phone off the charger at 6:00AM yesterday morning. Streamed an hour and half to 2+ hours worth of Pandora over wi-fi getting ready for work and then some in the car. Did some web surfing during the day, various other things. (No phone calls really, except a brief wrong number). 4 e-mail accounts checking every 30 minutes (one an Exchange server). Also have Touchdown running push e-mail for another Exchange mailbox along with the Touchdown widget. Played around with some GPS apps (new google maps, Places, etc for a few minutes). Battery was down to about 16% by about midnight last night.
My phone charged fully overnight (with power off). Was turned on at 7AM, it is now 11am, and am at 90%.
I do not use GPS, have nothing running, no emails or social networking status updates.. The phone is on standby on my desk. I only do a few text messages and 5 minutes of voice calls / day.
So this means I get 40hrs of standby time? That is a little ridiculous.
I chatted with AT&T tech support and they said that the AT&T stores don't have battery replacements yet, but I could get a full phone replacement since I am within the 30 days still.
But from what I am hearing, it seems most people are having the same issue if not worse, correct?
I really don't want to set everything back up AGAIN. I am coming from using a Samsung Eternity - understand it isn't a true "smartphone" - but I use it the same, and would easily go 3-4 days without needing a charge.
with GPS off, wifi off, BT off, no data sync or background data turned on, i charge it fully at night -
last 3 nights in a row, at midnight it was showing 100% and at 7:30AM it would show 97-98% remaining, and that was using the alarm, set to loud and probably ran 2 minutes before i'd hit the off button
From 7:30am-11am, I have used 4% of my battery. I have these things going on:
-Exchange sync (real time)
-Facebook sync (once every hour)
-wireless off, bluetooth off, GPS not being utilized
-Weather.com and a Google search widget
The battery use shows this:
-Cell standby: 48%
-Phone idle: 36%
-Display: 8%
-Android System: 3%
-Email: 3%
-Android OS: 2%
I've barely used my phone this morning, so I'd think 4% of use in 3.5 hours is quite acceptable. It sounds like you need to make some modifications to improve your performance.
firehazard - what modifications have you done? I have wifi/bt off, background data off, no email syncing - display brightness all the way down..
To anyone who is having very poor battery life, I suggest a factory data reset when you exhaust other options. My phone wasn't lasting me more than about 8 hours on a full charge, with light to moderate usage. After a factory reset, I just ran nearly 24 hours with similar usage.
I can't tell you what changed or what got removed, maybe it was an app that was running and draining the battery that I didn't see, but battery life is MUCH better now. Hell, everything is running much better, even the GPS.
I went from wanting to throw this phone at a wall and return it for my iPhone 4 again, to loving it in less than 24 hours.

I'm referring to him running wifi and bluetooth when he's not even using his phone. Stuff like that.
Just for recording keeping, when a phone company says their phone can last XXXHours in Standby this means, that all wireless transmitters are off. this means (for the most part) airplane mode, with bluetooth, and wifi OFF.
these continuous wireless transmitters are why you didnt get the 200Hours or what ever it is in standby mode.
I recently took my phone back to BestBuy for a replacement since my battery was trying to kill itself overnight as well. I did the full charge when I first got it and purposely ran the battery down to quickly get it to turn itself off at 0%. Did a full recharge and repeated this process about 3 times and last night my battery only went down 3% over 6 hours. Compared to the 30-40% that was draining before, I'd say the full discharge/full recharge works that people have been talking about in the battery threads works. Thanks, everyone! I use Y5 to have it automatically connect to my WiFi at home when it's in range. Not much more than the usual was left to sync (although JuiceDefender may be working to turn stuff off when my screen is off) such as Gmail, Beautiful widgets, facebook, and one rss feed.
Either that or I had a crappy battery before
Seems like some folks are having the same problem as me, while others are having much better results. Firehazard's situation and drain while not in use is pretty much in line with my expectations of the phone. With my old Tilt 2, I left WiFi and Bluetooth on all the time and still got great standby time out of the phone. When those connections weren't in use, they weren't really draining my battery in any way. I'm going to try to disable them though and see if that helps. I'll also try to monitor the battery usage screen and see how much power is going to wifi and bluetooth when I have them on.
I've been suspicious of my battery as well, tracking it casually today.
Took it off the charger approx 8:30am, immediately went to 99%.
Watching it over the last hour it appears to be losing 1% / 10 minutes.

Just using it for the past 5 minutes to write up everything running has dropped the battery almost 3%. Albeit I have terrible cell coverage where I am. It does seem that the cell and wifi receivers are a bit weak, or the meters are biased conservatively.
*edit* I want to be clear that I love this phone, I just want to try and find out what and if certain services/applications drain the battery and if not then if I have a bad battery.
Okay, so I turned OFF bluetooth and WiFi and checked the battery before bed and right when I woke up. This time, I lost 24% over 8 hours. Certainly a big improvement over 33% in 7 hours, but also no where near where my old Tilt 2 was. I would lose 2-3% overnight at the most with that phone. I checked the battery meter and the majority of the battery went to Cell Standby and Phone Idle. Those don't seem like things that can be avoided through tweaking. I was in an area with 3 bars of service (same as night before), so I don't think that was an issue.
I'm debating whether or not I should try a factory data reset. Some folks reported good results with that. I really don't feel like reconfiguring my whole device if there isn't a good chance for improvement. Maybe the GPS fix that's coming will help battery life?
Have you tried reconditioning the battery? That would be the charging/discharching cycles mentioned throughout the forum?
I have done it and my phone has been on standby for more than 24 hours and I am still at 50% battery. It's just had very light usage. Wifi on for about an hour, snapping a few pics, deleting some others. A bit of calc usage. When I first got it, my battery was dismal.
Mine hasn't been modded one bit yet, just installed some apps from the market and a weather widget.
Yes, tried that. It actually helped a little but I'm still getting poor results compared to some.
I have another theory/question. I use gmail as my only email account on my phone. Its set up through the system and it syncs to the gmail application on the phone. I also have it set up in the Samsung default email client (which I prefer). Am I wasting battery because the two apps are checking mail independently? Does the gmail account sync while the Samsung one checks at intervals (I have mine set to 1 hr)?

probably.

heavy usage drops my battery about 4-5% per hour. By heavy usage I mean playing 3D games for hours str8

[Q] Battery life not as it should be?

Hi
First of all I'm back on Android and back on the forum after four years of iOS, really enjoying Android and the forum again!
I just got my Z3 for about 2 weeks now and I'm not getting the 2days out of my single charge, when I take the charger out at about 7 in the morning, I'm left with about 30-40% at 11 a'clock at night. I'm just wonderring if these 2 days should be able to reach with heavy whatsapp usage (groups, really almost receiving a couple of messages a minute ) and moderate Facebook, Snapchat, browsing, and maybe some app downloads? Are there some settings you guys recommend to increase battery life? (already using stamina, doesn't really make a big difference).
Thanks in advance!
You can follow the battery life thread.
I have autosync, location and WiFi calling enabled and I still get 6-9 hours of screen time out of a 24 hr period with heavy usage with or without WiFi calling. At first I got no more than 5-6 Hrs screen time but as I used it and it settled/calibrated it got better.
Whats your signal strength like? It can have a big impact.
As for battery saving tips:
Try turning off or reducing the nunber of apps syncing. Facebook can also be a killer at times, I disabled, I barely use it and when I do need to I just use the mobile site.
Also turn off background WiFi scanning and set the following option -> WiFi off when screen off or on w/screen off only when connected to power.
Lastly try calibrating the battery as even Apple as you probably know reccomends for their devices:
1. Full drain
2. Full uninteruppted charge
3. Discharge with regular use to 0-1%
4. Full charge and use normally
As for stamina its not done anything for me either so I disabled it. More like placebo effect lol, I think they will fix it.

Thank you for quick response!
I've searched for a battery life thread but I couldn't find one, where can I find it?
My signal strength most of the time has all the bars, except at my house I have only one or two bars in various rooms, I didn't know about its big impact so this might indeed be a reason for my battery drain. Turned off almost all the syncing for my apps, and did the WiFi settings you mentioned, if the setting 'WiFi off when screen off" is enabled should my WiFi be of when I light up the screen without unlocking my phone or just really when the screen is off? Thanks for the tips, I hope I can get more hours out of it now!
At some time I had a short battery too and after those same steps I have 3 days battery without any problem:

The battery thread is in "General" its called "Battery Life is Insane".

[Q] Current drain in sleep measured with CurrentWidget

Hello guys, I had some battery trouble with my Nexus 5, and during my investigations I saw something strange.
I used CurrentWidget app to track my
current drain, during wake and during sleep. Settings: Update Interval = 10 sec, Log Values to file = true, Force Log in sleep mode = true.
When I viewed the log as graph I saw that during sleep the current drain never decreases to something close to 0 mA, it stays around 100 mA,
or goes down to 30-40 mA, but absolutely never less than this, as you can see in the attached screenshots.
I tested and confirmed this behavior with 4.4.4 and 5.0.1, both flashed clean with factory images, without any other apps installed besides Google apps. During the tests I kept the phone with normal usage: WiFi on, 2G network, Bluetooth on, Location Battery saving, Auto-sync on, and just some net browsing. But of course the most important information was collected during sleep with screen off. Surprisingly, by putting the phone in Airplane mode the current drain in sleep remained exactly the same, between 30-100 mA.
I also tested this on a Nexus 4 with 5.0.1 and during sleep it consumes around 2-4 mA, so there is a big difference.
Can any of you also install the CurrentWidget app, configure the logging, wait a few hours than make a screenshot of your current drain graph ?
I want to see if it's something abnormal with my phone of if it's a general thing. It would be very grateful. Thank you.
Is the widget keeping the phone out of deep sleep? A la wakelock... Just a theory.
what are your wakelocks ?
try gsam battery monitor,
i thought currentwidget drains the battery,i only used that program to check charging current and display idle, but never kept it when display was off.
or try betterbatterystats

I'm not interested in wakelocks, just current drain.
And no, I don't think it's keeping the phone from entering deep sleep, it just wakes up from time to time to log the current.
Anyway, the same app with the same settings on my Nexus 4 records 2 mA in sleep mode, so it's definitely in deep sleep.
So , please can you do this experiment on your phone and share the results ? Thank you so much.
I very rarely got below 27mA. Though I've no idea of it was in deep sleep at that time.

An even better app that can log the current drain of the phone is Battery Monitor Widget. I configured the recording interval to 10 seconds for testing and played with the Graphics window.
The first picture is from a friend's Nexus 5 (stock 5.0.1) and the second one is mine (stock 4.4.4, but same tested on 5.0.1),
As you can see the current drain even in sleep never decreases below 30 mA and the mean is around 100 mA.
This is very bad, because even the Nexus 4 with 5.0.1 has a 3 mA drain in sleep,
so why is the Nexus 5 drain from 10 to 30 times more ?
Can someone shed any light on this ?
At 100mA drain, your phone would hypothetically last 23 hours. 100mA * 23 hours = 2300mAh. I doubt that. It surely must last longer than that, if it is indeed in deep sleep and not kept awake by some application.
My hypothesis is that what you're seeing is a calibration error. The current measurement is more than likely inferred by accounting for other factors. (I doubt the current is measured directly - ie. as an ammeter). Therefore, I would suggest taking it with a grain of salt.
That being said, with all things being equal, if someone were to do the test, they would probably get similar results to you.

Can you please do the test on yours?
My results are comparable to yours, andreipaval. The current sensor was more than likely designed for limiting charging current and not for measuring sleep current. Plus, more importantly, the phone definitely has to be pulled out of deep sleep to even make a measurement. The sensor being off by less than a hundred milliamps makes little difference when one can charge at much higher rates but it will falsely report the idle drain.
Perhaps it was your Nexus 4 that was off by -100mA and falsely reported 3-4mA. It can safely assumed that the internal leakage of the battery itself is probably more significant than 3-5mA... Thus, as I previously suggested - you might want to consider taking this with a grain of salt. If you want to do a more conclusive test, see how long your phone lasts from 100% to 0% in deep sleep and airplane mode. You can get a pretty good estimate of the drainage that way. (Batt capacity divided by number of hours)

I have looked into this myself recently using software readings from Current Widget and agree with your findings. Basically once the phone enters true deep sleep the measurement intervals increase until it's the only process waking the phone and measuring higher rates than would be found without the software waking the device.

Can any of you also install the CurrentWidget app, configure the logging, wait a few hours than make a screenshot of your current drain graph ?
I want to see if it's something abnormal with my phone of if it's a general thing. It would be very grateful. Thank you.

I have made a log of power level readings with Current Widget in various forms of usage. The update interval was set to 5 seconds but you can see at the beginning when the phone was mostly idle the update interval becomes delayed and sees above average idle measurements. Compare this to after when I began to listen to music on the phone with the screen mostly off. Here we can see lower numbers while the phone is actively playing music, less so than before when the phone was said to be in deep sleep. There are periods of idle followed by various periods of screen usage following that, more details can be found in the album included below.
There's also the case of background software drains. Things like Google Now and Auto Syncs kicking in, and whatever other apps and services may be installed. These results were with Google Now off, Locations off, Hotword off, Auto syncs on, and Adaptive Brightness on set to 40%.
I took screen shots of my usage having ended the voltage measurements at the 45% mark of this charge.

You got almost 6 hours of SOT from a single charge? How did you do that?
It seems impossible to me...
Well, I get anywhere between 5 to 6 hours of SOT if I use the phone heavily (continually). If I'm working and just using the phone regularly, I get between 3-4 hours of SOT. I assume it's the moving around, changing cell towers, turning WiFi on and off and things like that. Also, web browsers are notorious for ramping up CPU frequencies, and hence power drain. I can get 5-6 hours using Tapatalk but not playing games and browsing the web.

Battery life is determined mostly by usage, settings and signal. So the apps I used, with the settings mentioned, on a strong WiFi signal.
There are ways I could increase battery life further such as lower brightness, disable auto syncs (or have them set on an automated schedule like I was forced to do on Kit Kat) or even disable Dashclock despite its minimal attributed drain. There are also always random factors such as incoming calls, texts, app updates, etc.
Generally the Nexus 5 is great on battery using WiFi, but only average when using data connection or making voice calls. This can be seen in Anandtech's review back from Dec. 2013.

[Q] About Battery Life

Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Install Gsam to see if you can gain any more insight into whats causing battery drain.

CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.

odd battery usage stats, poor battery life

hi
i have a new (3 months old) unrooted nexus 5 update to latest OS version which is showing some very odd stats wrt battery consumption.
first i had heavy battery drain but then i disabled the scanning options in the location menu which helped. but still even with brightness at only 18%, battery saver on 95% of the time, location & mobile data off all the time & wifi only used for short bursts it still seems to drain quite quickly.
app usage stats as reported by the inbuilt battery stats option differs quite a bit from other battery management apps (du battery saver, battery doctor, gsam battery monitor)
for eg. inbuilt battery stats doesnt even show wifi consumption in the stats even if i use it for few hours (then suddenly one time it showed up with some excessive consumption stats - 1500mah for 2 hours usage; photos attached). very often it shows gravity screen app as the biggest consumer of battery while other apps show gravity screen as consuming very little power. otoh gsam shows battery doctor as consuming the most of all the apps.
what could be the issue?
gsam shows average battery life with screen on as 3h 42m. is that ok?
was also wondering if the optimization options of the battery management apps work or are they gimmicks? for eg both du battery saver & battery doctor show 'x' number of apps consuming power in background & when you press the optimise/close apps button it shows some cool effects of shutting down those apps but you come back after a few hours & the same apps show up in the running in background.
also, the front camera is very grainy. cant believe its that bad in what was a flagship phone. is it just my phone or is that the how it is for other users?
anyone with any inputs?
You got nearly 5 days on a single charge??? Yes, your battery consumption is fine. Nearly 4 hours of SOT is fantastic.
The graininess of the camera will depend a lot on the lighting. Unless you have a light shining directly on your face, the picture is probably pretty dark. That said, it's "only" like a 3MP camera. It's well known as a sub-standard front camera (I'm not a selfie machine so I don't really care). When you think about how microscopic the light sensor is on the front camera, it's no wonder the picture is grainy.

thanks for your reply exninja
that 5 days was a one time thing where i barely touched the phone & then only to test it. i wish it were that good LOL. normally i get about 2 days with very conservative usage (brightness at only 18%, battery saver on 95% of the time, location & mobile data off all the time & wifi only used for short bursts, 0 talktime)
is 4 hrs SOT that good? i see a lot of people getting 5 to 6 hours + & that too without those conservative usage patterns.
the thing that got me worried is the strange battery usage stats reported in the stock settings.
Honestly I wouldn't worry that much about what each app says is using energy. They're each consuming very little anyways. I'm not familiar with gravity screen so I wouldn't know about it.
I haven't heard of many people getting 5-6 hours of sot, especially since lollipop. I got 4 hours on KitKat, then dropped to 3 or less on lollipop. Now it's usually around 2 hours.
@fguy76
First of all, just to let you know, recently Google Play Services have been acting up. Sometimes I get normal battery drain overnight when I sleep, and sometimes it drains like crazy. For now, there is nothing we can do about Google Play Services.
However, if u noticed that WiFi has been turned on the whole time via the battery history chart, despite the fact that you did not even turn on WiFi at all during that period, then this can only mean one thing. You must have enabled WiFi Scanning (the famous Scanning always available bug in Lollipop & KitKat).
To disable WiFi Scanning, go to Settings first. Then on the top of settings, there is a search bar. Type in "Scanning".
Then u will see the following options. Make sure u disable WiFi Scanning.
Having said this, there is another annoying bug. This bug is when you have left a WiFi hotspot and forgotten to turn of WiFi. So after awhile u realised it and u proceed to turn off WiFi. But hours later, u check your battery stat, and it still shows your WiFi have been active the whole time despite turning it off. For this, the only workaround is to reboot the phone. To avoid this bug, always turn off WiFi b4 u leave the WiFi hotspot area.
@pcphobic i have wifi scanning off & i always remember to turn wifi off when not using it so that second scenario is not an issue with me

The other solution that I can offer is under Location settings, go to Google Location History and make sure it is turned off.
You can still use GPS based apps with Google Location History turned off.
I suspect that if u find intermittent wifi showing up in your battery history, it could only mean that Google Location History is periodically waking up and using wifi to get an approximate location. I used to get this until I turned off Google Location History.
