Battery Life on Wifi - Outstanding!!

Basically, when I leave wi-fi on my phone has incredible battery life. If someone has already mentioned this feel free to bury this post, but to my knowledge it doesn't seem this has been posted yet.
With wi-fi off and 3g on
- Battery lost 5-6 percent per hour
Wi-fi on
- Battery lost 1-2 percent per hour (sometimes less than 1 percent depending on what your doing)
Right now after having my phone on for 34 hours my battery is still at 70 percent! I'm fairly certain this is because it disables the 3g radio altogether which apparently is a real battery hog. That or maybe my phone is just a fluke. I really don't know.
This also seems to be tied to the htc sense rom (correct me if im wrong) but if i remember correctly battery drainage increased when wifi was enabled in the stock rom. Currently, I'm using the latest htc sense rom from modaco, I'd really enjoy hearing if enabling wifi helps others extend their battery life.

your having better battery life with the Desire ROMs? that odd, my battery life with a Desire ROM was 20-30% worse compared to stock.

Actually, it's a well known fact that 3G uses more power on most (every?) phones than Wifi... so you're not alone.

Hey when you say WIFI on..do you mean WIFI and EDGE or did you completely disabled the radio?

I never would have thought having wifi on would extend battery life to such a great extent though, in most of the latest cell phone reviews and what not everyone recommends to have wifi off saves battery life but in this case just the opposite is true. I kinda knew the wifi was more efficient but I never expected such a large benefit from leaving wifi on all the time.
@ram130 I haven't actually touched the radios at all so I expect them all to be on or at the very least have edge on, I am able to receive and send calls and txt so I'm assuming at least some cell radio has to be on. All I did was use the htc sense rom and enable wifi.

The cellular radio is still on, but 3G/Edge (data) are disconnected. I don't know how Edge compares to Wifi, but 3G is a battery killer in comparison.

In other words you have "use 2G networks" checked right?
I'm gonna try this is now. I'm currently at 3hr 32m unplugged with 80% left. I have wifi enabled and on the stock rom. So I'll post back when I wake in a few a hours and see how it goes.
My only problem:
Wifi seems to disconnect alot during the hour regardless if sleep policy is set to NEVER. My wifi signal is -78dBm to -86dBm in my room and on channel 11(used wifi analyzer). Any suggestions why?

I have the same experience at home, I enable Wifi and leave the phone stay home for a couple of days and battery still 40%, when I go out and wifi is not connected, 3G kicks in and battery drops much faster.
I'm using cyanogen 5.0.4.1

Interesting. Did not know this!
I guess I won't feel so bad about leaving my phone on Wifi all day!
Also, does anyone know how much power is used by not having a radio signal and letting it constantly search? That seems to destroy my battery. But sometimes I am in an area with wifi but no radio access (deep within a building).

It's too bad this phone doesn't have UMA - that would make up for T-Mobile's lack of indoor coverage (at times), and probably improve battery life a lot in some cases.
But I have to say that on another phones I've used, especially WinMo devices, using WiFi instead of 3G seemed to always use more battery. But, it could very well be different on this phone...I'm definitely going to give this a try.

im not sure about the percentage but i agree,the battery drain is considerably more when searching for radio.im in a building most of the day and it doesnt take long.miss the UMA i had on my bberry.

I also Get. About 25% better battery on wifi

Well after 10hrs of the phone being on stand by I woke up. It was at 46%!! my god. Anyway I checked my email, read an article all taking around 15mins and guess what? I had 30% left!. I put it back to stand by for 3hrs and took a look at it and had about 16% left...
It is now charging after one hour with just 10min use of downloading apps ..Can ANYONE tell me why my battery is draining so much on wifi? When its on EDGE for the night after 10hr I would have around 70% left from a full charge. Anyone can help me out here?
I shall be getting a replacement battery for free Tuesday.
Stock android.

Did you set your phone to only use 2G networks also? If you're not charging, wifi will probably disable after not being used for a while..so it's probably rolling to 3G if you haven't disabled it.
I'm not saying it's convenient to constantly switch back and forth... but this explains why it may not be a good test of the battery life the way you're running it.

Well yes I have it on 2G only. Any thing else could be contributing to it dying so fast?

Well I found a way to use my laptop as an AP. So I connected my N1 to it and getting full bars(-41dBm) in my room now. No wifi disconnects so far!(maybe it was my linksys before ?).. So far the battery is at 86% with some 3D games, been unplug for 1hr 50min now. I'll put it to stand by now and see how it looks after 10hrs.
I'm on a stock firmware(not rooted). 2G only selected.

The way I understand it is as follows:
Phone is on STANDBY:
3g==2g* which are both more efficient then wifi (that's why the default wifi policy turns wifi off if it's not being used)**
Phone is ACTIVE:
wifi is more efficient then 2g/3g because:
1) It's waaay faster and thus causes less battery drain* and
2) The AP (router) is much closer to the phone then the cell tower so in theory it doesn't need to use as much power to talk to the router.
*http://code.google.com/events/io/2009/sessions/CodingLifeBatteryLife.html
4:45min into it there is a power usage chart and 3G/EDGE idle power usage is about the same - also somewhere else in the video they talk about wifi vs 3g usage when transferring data.

Someone needs to test this ok. ...already testing wifi

Ok I'm at 11hrs 30min on wifi and its at 67% with light usage(checking email, news for 5min)..improvement? kinda, because since turning off my laptop it switched back to getting low signal(-81dBm) from the router in the next room. Weird? I'm still thinking. anyway I'm heading out so gonna use the phone more today, lets see if it gets me through the day.
Still no where near the thread starter 30hrs!! Maybe stock really sucks? bad battery anyone??

@ram130 I'm not sure how my battery is lasting as long as it has so far. I'm up to what would be an insane number, 65 hours 36 percent left .. this battery just wont die. I haven't the slightest idea how it's lasting this long I just leave wifi on all the time and turn wifi standby off. If anyone could explain how leaving wifi on more than quadruples my battery life I'd sure love to know.

Battery Drain, almost solved. Need help from Dev.

Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

To say that i would also like this "bug" to be solved

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!

How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?
《tapatalked from galaxy s3》

If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.

I am satisfied with mine

ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!

Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.

I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.

Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.

Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."

My suggestions for better battery life

Hi,
Below you will find some tricks i use to increase standby time and force less resource consumption leading to a better battery life. I have tested all these things a number of times and my device's battery performance is upto the mark when i follow them.
1. Disable Moto tips n tricks in Settings > Motorola privacy > Uncheck Help motorola and Moto care
Everyone by now knows how to use moto apps and their added benifits so there is no need to enable those options. They use data in the background. By turning these off you not only save data but also prevent wake lock leading to better standby.
2. Use active display cleverly
I dont use the option to turn off notifications at night. But all the notifications recieved during my sleep are shown by the active display leading to battery drain even though the device itself is asleep. So, the trick here is to place the phone on its back or put the phone underneath a cushion tricking the proximity sensor into thinking its in a pocket so that active display doesnt show any notifications.
3. Disable motorola security in Settings > Security > Device admin > Motorola device privacy
By default google's android device manager is on which helps to locate device in case of theft. So there is no need to get the same benifit of android device manager by motorola. All it does is use data under google services. Again less data consumption and better standby time.
4. Google location reporting
I dont use google now. And everyone who doesnt should disable google location reporting in Setting > Location > location reporting. If you use google now then it is not a better idea to disable location reporting because it helps to provide info about places nearby but if you dont use google now unchecking location reporting helps to save data and unnecessary wake locks.
5. Retrain Ok google now
If your moto x wakes up to voices not even close to the phrase ok google now in a crowd or a noisy environment then you need to retrain the device. Speak the phrase loud and clear. This helps me to avoid unnecessary wake ups.
6. Check you ram usage under Settings > Apps > Swipe left
This is suggested everywhere but the actual thing to note is the service section. Simple apps like Aviary (photo editor) keep a service running in the background. Remove all such apps. It helps to avoid unnecessary ram use and keep the device smooth after days of use without restart.
7. Battery percentage in status bar for better Screen on time
I use Du battery saver to indicate the battery percentage on the status bar. Weirdly my device would charge slowly but provide way better screen on time. However it behaves normally if i turn of the battery indicator. I have no idea why this happens but i have tested it and this trick works on my device.
8. Turn of scanning when wifi is off
Goto Settings > wifi > in options de select avoid poor signals and scanning always available.
9. Charging with a full signal
Whenever you are charging the device be sure to charge it in a place with full signal. I have noted that when i charge the phone in a room with three signal bars or low it charges slowly as compared to full signal. Although this maybe because of different power sockets but i have tested this on two sockets located at a place where i get one maybe two signal bars and two another sockets where i get full signal. It works for me.
I will update this thread if anything else comes in my mind.

I already do all these (and a lot more actually) and i just barely make it through a day if i don't really use my Moto X (X1056). Love the phone and all but it's battery is not up to snuff at all. Just got tired of spending time babying the battery and now just use my phone. Have a Targus 6000 mAh external battery thingy i keep in my tote bag that comes in handy every now and then.
In my opinion and experience, the 2013 Moto X and great battery life are not synonymous at all. I just deal with it.

I am going to disagree with you. I think the battery performance is way above average. I have attached some screenshots. Check them.

I'll give some of these a try, the problem I usually have is my phone thinks that it is much more dead than it really is. I think this instance it was on 1% for like 8-10 hours.

I do know about the 1 percent bug but i think it to be a hardware problem rather than software. I have a similar problem with my car. The nossle that pours gas in the tank cuts off automatically even when the tank till has the capacity to get 10 litres of petrol in it. The car company told me that the sensor is placed incorrectly in my tank leading the nossle to cut off way before the limit. Similarly the battery circuit may be wired incorrectly but this is just a theory.
Adding to my list of suggestions-
1. Switch to 2g when using wifi
If you use 3g/4g in an area where signal strength is not that high the phone would constantly force its modem to not only maintain a steady signal but also to get maximum signal which causes battery drain. So if you got wifi installed in your home or office, switch to 2g and save battery. Goto Settings > More..> Mobile network > Preferred network type and toggle accordingly.
2. Google + auto back up
Photos app that is a part of google + app automatically backs up all your images on the cloud. Many people are unaware about it and the back up happens in background. This uses a lot data. To cancel this open photos app and in options goto settings and sign out of your account. Some people may use this feature but i dont because it backs up every image stored on the device - whatsapp images, screenshots, viber the list goes on.
3. Google sync
Goto settings and scroll down to your google account. Uncheck all the options which your device doesnt require syncing. Since i dont use google play books tv i keep them unchecked.

Are you running stock? I'm thinking about putting in a warranty claim on my device. I'm currently at 61% battery. 5.5 hours on battery and about an hour screen on time. did use maps for about 5 minutes, but even then, not close to what many other users are getting. I've factory reset multiple times. Don't want to unlock bootloader as it's still under warranty.
Going to call Moto today.

Yes i am running stock. Never rooted never felt the need to. Although i like to tinker devices but within the limit. Before calling in for warranty try disabling google now for a day. I am sure it wont hurt. Also check the times your device got awake in the battery section. The key here is to extend standby time. No one can magically increase on screen time of a device beyond the battery capability but what can be controlled is the standby time. If you arenot using the phone it should be figuratively dead. And seeing the information you provided i can judge your device remains awake. My average run with the battery is about 22 hrs including 4 hr screen on time.

Ill turn off Google now and see what happens. Here is a screen shot. I was an avid android user the last four years, but have been using and iPhone for the last 8 months (for work). Recently switched back to Android and thought the battery on this device would be great but haven't been happy.
Attaching a couple screen shots. Have less than a couple weeks to submit warranty so don't have a lot of time. I'll give it a day with Now off and see what happens.

After watching the screenshot i suggest you switch to 3g. Your device is getting poor 4g coverage which is the only reason for heavy battery drain.

Thanks - tried that. My only options are Automatic and 2G only. No option between 3G and 4G. I usually have better signal, but I'm in my basement working from home today. When that's the case should I switch to 2G? Signal is the same. I guess I could turn off mobile data when I'm home and on Wifi. However, if I'm on wifi, do I need to worry about that or does being on Wifi turn off mobile data? It's been awhile for me.
I really just want to make it through the day on a charge. I normally only have a couple hours screen on time, but even now, I'm lucky to get ten hours. took your advice and turned off Google Now. I'll see how the second half of the battery goes.

When i switch to 2g i never lose a signal bar. Never. So if you see yourself in a situation like today where signal is low i strongly suggest you to use 2g. Since you are connected to wifi your modem doesnt need to pull data. I get that people want atleast a day's battery life out of their phone but this hassle of 3g 4g is really what bogs down battery life. Another thing to lookout for is location reporting. Since you have turned off google now turn off location reporting as well.

Thanks for all your help. I went ahead turned mobile data off since I'm home. I'll keep an eye on signal and try to use Wifi when I can. I do have location reporting off (I only use it when I need GPS, which isn't too often).
When I switch to 2G, my signal remains the same. Does that sound right? Or is 2g just going to use less power, regardless of signal?

I definately see change in signal strength when i toggle between 3g/2g. And yes 2g uses way less power. Again i am not sure why you are getting the same signal on 2g.

Thanks again for all your help! Closer to 11 hours in and around 45%. Only lost about 15% in last 4ish hours versus 35% in first 5. Turned off Google Now and switched to 2g when on WiFi. Location is also off. Guessing guys that get 4+ hours SOT are doing the same. Bit of a pain to have to toggle between 2g and 4g. I'm guessing I can download a widget to make it easier.
Anyway, you rock.

I am going to disagree with you. I think the battery performance is way above average. I have attached some screenshots. Check them.

Whether you agree with me or disagree with me is irrelevant. At the end of the day, it is MY experience, and what I experience using MY Moto X. Is it improbable that we both have dissimilar experiences and usage scenarios?

those are some nice suggestions, but some of your paths were not found (e.g. Motorola Privacy).
regardless,
a.) there is already a battery life thread
b.) battery life is going to be what you make of it, and there are numerous variables - even within the same country or carrier
but if you are going to report your battery life experience, be sure to give full detail so that folks can make an apples-to-apples comparison. For example, below are mine for a typical weekday:
carrier: VZW (maryland)
off charger time: 16 hours (6am - 10pm)
wifi: on all the time (about 6 hours connected to wifi)
mobile data: set to Global and on all the time (about 10 hours connected to mobile data - no wifi connection)
bluetooth: on all the time (and connected to Moto 360 watch, with 1 hour total connected to my car)
location services: on all the time
touchless control: on
active display: on
google now hotword detection: on
GPS: battery saving mode
root: yes
unlocked bootloader: yes (although this REALLY shouldn't make a difference, but I have noticed worse battery life after unlocking - could be due to after a reboot, the system does not revert back???)
system partition: DALVIK
ROM: Krypton 4.4.4 or stock 4.4.4
total screen on time: ~2 hours
battery saving apps: greenify
other apps: Xposed with gravity box
prior to the 4.4.4 update, I would get 3 hours easily, now I barely hit 2. my reason for leaving everything on is that I like to have my day/life as seamless as possible. i don't want to have to worry about turning on/off wifi/bluetooth or any other features. a smartphone should be usable for at least 24 hours with at least 2 hours of SOT without having to tinker with it all day.
hope this helps.

Android OS - Keep Awake and Mobile Radio Active

Hi,
The Nexus 6P has been pretty good so far on battery. Nothing super insane, but enough to get me through a day.
Max I get is 3 hours SOT when I hit 0%...
Android OS is usually in the top 3, and in a 10 hour day, its getting 2 hours of Keep Awake time and about 30min Mobile Radio Active.
Google Play Services is also getting around 45min Mobile Radio Active as well.
Phone is bone stock, bootloader locked, unrooted. Running a handful of apps, even stopped using my Moto360 and disabled bluetooth when not in use to see if that was the culprit.
Any tips? (or apps that help me delve deeper into Android OS and why it keeps waking the thing up)

would also like to know about this, having very similar stats

Similar situation here - crazy battery drain and "Keep Awake" when I have a sim card in (TMo). 3 hours sitting on my desk - not using it - the phone gets warm/hot and Keep Awake shows 1H 16m under Android OS. When I put the same sim back into my Nexus 5 (using the adapter/converter) the N5 battery is perfectly fine.. normal.. no massive drain.
Any thoughts?

Turn off Wifi and give it a try. See if you still have the same battery drain.

Go into location & uncheck all scanning functions

Thanks. I should have mentioned that I already had wifi and bt turned off, and had turned off scanning for both under Locations. I was trying to isolate this to cell signal as best I could by disabling wifi and bt things. I also tried turning off "Enhanced LTE" - and now I'm trying it with wifi calling on (again just to narrow down different possibilities).
I think a factory reset is in my near future - may as well start from completely scratch and see if I still get the same horrible battery drain.

Just reporting back. I did a factory reset - and INITIALLY I thought I was on to something. Battery life seemed better at first, but then I soon began dropping cell signal - which apparently sends the phone off searching for signal chewing up battery.
In my case it's never ending cycle - get signal, drop, search, get signal, drop search.
Yes, I'm in a fairly weak TMo LTE service area, but my Nexus 5 and my wife's Nexus 4 have never had these sort of massive drain issues.
Also, I was in a major metro area on Sat night and the signal kept dropping as well. I couldn't toggle it back on via airplane mode or the mobile data switch. I finally had to reboot to bring it back - and then it proceeded to drop again. Meanwhile, my wife's N4 had no issues.
I went to TMo on Sunday and swapped out the sim - no change. 6P went from fully charged to completely dead overnight (roughly 1AM to 9AM).
So, at this point I'm wondering if I just have a faulty 6P. I'll be calling Google today to see about an RMA exchange :/

Maybe try activating band 12?
http://forum.xda-developers.com/nexus-6p/general/fastboot-activate-band-12-volte-t3239652

I found that my wifi network was causing doze to not work as good. I turned off wifi at night last night and got better results with just data.
My radio is accounting for 88% percent of my phones battery drain. I was down to 60 percent with about an hour of SoT. Not sure what's going on with my device either. I was about to factory reset but don't want to.
Bums me out when I see people getting 4+ hours. I want that action.

I had the mobile active bug also, very close to getting an iPhone.

I saw in another thread that apps like GasBuddy has been causing wake locks like you describe. The issue may be app related. Rooting and installing a battery monitor app should give you more insight as well as wiping and loading just your basic apps to find the culprit because something is definitely wrong.
I get 6 hr SOT without doing anything special and at night I lose 1%, sometimes none if I only sleep for 5hrs and that's with wifi on.

Phone Idle under Settings/Battery

What runs under "Phone Idle" on the V20. It's been the largest battery consumer for the last week of use that I've noticed. My wife's V20 is the same and I had my brother check his and his wife's V20.
I'm only asking because I'm not see great battery life like other have been reporting. I don't have live wallpaper, have only two widgets on the home screen. GPS is set to battery save, screen is set to auto but that doesn't even come close to chewing up the battery.
Sadly I feel like I'm still using my old 2.5 year G3 where it'll need a charge mid way through the day.

Really??
Pretty sad that needs to be done on a week old phone with minimal apps. I'm not even a heavy user.
I feel like I'm back on my old DroidX days where everything was a factory reset but never helped...

I agree with you. Although my phone is just beyond a week old and does have all my apps installed, a factory reset can't be the solution here. This is the typical "I don't know how to fix this" answer always given by manufacturers and carriers.

In the roughly 3 weeks I've had my V20 I've only seen this once where phone idle was higher than Screen. I started looking thru all running apps for 'keep awake' time being high and noticed Android OS had keep awake of over 2 hours when it's normally less than an hour after a full day use. I power cycled the phone and it stopped.
The weird thing was Android OS didn't show high battery usage even though something was triggering keep awake. Looks like the keep awake was causing phone idle to be high.
I'd look at everything in your battery usage to see if you have any high keep awake times.

Sorry did not mean to be short in my response. When you set up your phone did you restore it from another phone using the nfc bump thing? I did the same and my phone battery was the same way. Wouldn't last even half a day. After i factory reset and set everything up manually i get 18+ hrs with 7 hrs screen on time sometimes.
If this situation doesn't apply to you then maybe a reset won't help. But you have to understand your situation isn't normal.

Make sure Google now features are all turned off and not running in the background.

I'll have to go through the apps one by one like I did previously on my G3 and see. Now within the battery stats there is only a handful of apps like hangout, play music, chrome and camera. The rest is OS related so that's why I was curious what ran under Phone Idle.

No and sadly I was looking for that feature a week ago but couldn't find it so I had to individually install most of my apps I had on my previous phone...made for a long night along with the additional emails and configuration or icons and such.
I'll keep digging away at the phone...I really want to like this phone ?

Has there been a definitive resolution to "phone idle" battery drain? I just got a V20 2 weeks ago on sale for $360 and its a fantastic upgrade over the One+1 I've been rockin all these years, but I'm also suffering from mediocre life due to whatever phone idle is. Some forums (for other phones) say phone idle is related to your wireless signal. I'm still with the same carrier and frequenting the same locations and had no such battery drain with that old One+.

i finally discovered whats was goin on with me..
i had the same issue..
phone idle was topping my battery usage list
it turns google plays have this "locationmanager service " and locationwhatever" that kills your battery over wifi even with location button off

Go to locations/ 3 dots in top right corner/ turn off WiFi scan. See if that helps.

My phone has been suffering from poor battery life for quite some time now, here are the screenshots, Android OS has been this high on almost all battery cycles.
I disabled wifi scanning as suggested above and will watch the performance, does the community have any other inputs to fix this? View attachment 4212978View attachment 4212979

Phone idle is always the biggest battery draw on my phone too. I have minimal apps too. No Facebook or similar types of apps. I'm on a Verizon V20 stock with the latest security update. Is this normal V20 behavior to have phone idle consume more battery than everything else?

how about doze mode , isnt that meant to help with this sort of problem ? ( my phone is currently on a ship )

Any update. İ have the same problem

So what did you do?

Would also be grateful if anyone shared a solution.
I specifically have a SIM-unlocked Sprint model (LS997) which am using in Europe with another carrier.
Using it in LTE preferred mode drains about 10-15% overnight.
Using it in WCDMA preferred mode drains up to 5% per night (yes, wifi and cellular data OFF and many apps greenified) . So I'm really interested in how this can be fixed and achieve 0% battery drain across several hours.
Or maybe it's SIM-unlocked Sprint ROM related?? I can't root my phone since it has the Feb 2017 patch and is a ZV6.
I suspect rooting it and using another ROM would solve this + the annoying issue of not being able to send images via FB Messenger and Viber while on cellular data (I imagine the Sprint guys placed some kind of restriction to deny media transfer for these apps when using cellular data).

I have noticed this too.. wondered why "phone idle" takes most battery... any suggestions would be great!

I am also curious about the solution. Phone Idle is at top. Even without SIM card. 30% drains during a night (everything is disabled, but no airplane mode is on). I tried factory reset, reinstall older ROM, replace battery, use no app but still sucks.

hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state)
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.
