Battery drain on WIFI and 'Android System' - Galaxy S I9000 Q&A, Help & Troubleshooting

I keep reading that mobile data is supposed to consume more battery than WIFI, but whenever I have WIFI on, I drop a percent every couple of minutes. And this is unusual, because I undervolt and generally have much, much less drain on mobile data.
When I check the battery stats, its "Android System" that is taking a lot of the percentage, not the WIFI itself. I think this is because my system is set to update only on WIFI or something. Does anyone know how I would shut this off? This only happens on WIFI, not mobile data.

Hey there, what firmware are you on?

[Q] Battery usage issue: battery cronology and force close

Hi, i have an issue about battery drain here in froyo with official rom and speedmod kernel.
I notice a 4% per hour in stand-by drain.
If i check with *#*#4636#*#*, under "battery cronology", watching network usage i find something strange...
the most used application , more than email and everything else, is called "0".
When i try to click on it, watching details, i have a force close.
Is there something i can do ? i wouldn't wipe all data to check if i resolve...
Thank you
The same for me.
I have a big battery draining when the phone is on stand-by. For example this last night, i fully charged it, and in 12 hours the battery drained a 10% without using it, with juicedefender installed and configured to auto on 1 minute every 15.
I think that i dont have the gallery sensor issue, but my battery drains more than i think is normal, and i have the "0" under network usage, and get force close when clicking it.
It's the same for me as well..anyone knows what the '0' is??
I'm on JPA build.
same thing happen to me.........try to off your data plan and it will save lots of your battery juice.........unless u are really checking email on your phone of course this doesnt help!!
is it normal to lose 20% charge in standby within 4 hours? i have almost everything off and it still drain my battery like crazy. Sync is off, data is off, wifi policy is sleep when screen is off, gps off, bluetooth off. Anything you name it i have it off. I have "spare part" installed and looking a the stats i don't see anything else eating the battery life. Only thing i see under other usage. is "Running (33.9%)", "Screen on (9.3%), "Wifi on (100%)" "wifi running (61%). Could it be the wifi on at 100% eating my battery?
same problem here
if data is ON overnight, battery drain is very high, like 20% in a few hours (5-6h).
if data is OFF, battery drain is almost 0 (zero)
in iphone 4 when my data was ON overnight with 3G and PUSH turned ON, battery drain was somelike like 3 or 4%.
Something is terribly wrong.

[Q] Battery drain when Data connection on

Have anyone noticed tremendous battery drain by just letting the phone accessible to data connection? I reflashed the entire firmware, did not install a single app, neither used the phone for anything. My device drains 7% of power in an hour by just idling.
However, if I use wifi only(sleep policy:never), I will have up to 80% remaining after a day of moderate use.

Mine drains 2% within the hour. ... wifi and gps turned off.
Maybe try battery calibration...

How to tackle my Z3C battery drain issues?? I'm fed up

I'm fed up a bit for my Z3 C battery life. This is my second query regarding battery life.
Does keeping Mobile data and Whatsapp running ON even in standby mode drains the battery??
I usually get just 1 or 2 whatsapp messages in an hour or two.
My phone settings-
Always turned off my wifi/ bt/ nfc/ gps/ location tracking/ autoupdates etc. & everything you can think and suggest.
Use only stock custom wallpaper and no live stuff. No widgets. No sd card inserted. With only two hoemscreen wih just 2 shortcuts on each screen.
Have disabled apps which I dont use.
Stopped services of apps which are no longer needed.
No auto sync enabled for any app.
Display brightness is at 30% all times.
*****************************************************************************************************************************************************************
I use only these 3rd party apps-
Status bar mini
Network monitor mini
Whatsapp
Greenify
*****************************************************************************************************************************************************************
My daily Z3 routine-
At night while going to sleep I turn off mobile data, turn on airplane mode and turn on stamina mode. (12:30am - 9:30am)
When I wake up the next day battery is down by 4-5%.
During day, phone runs in normal mode without any stamina activated. (10am - 12:30am)
*****************************************************************************************************************************************************************
The Low-battery mode seems useless as it does literally nothing.
Also, as soon as the battery is 100% charged and if I use phone for even 5 mins the battery immediately drops to 99%, so is this normal??
Even if I capture 5 photos in stock auto mode the battery drops by 1% or 2.
I reboot my phone once a week or in 10 days or when need arises.
Ram utilised is always 1gb. But I dont feel any slowness for any app or my phone usage.
But again I dont watch any movies or play games fearing my battery will deplete in no time.
I use 2G/edge network as 3G isnt available for my operator in the city I reside.
Charging the phone to 100% from 14% takes 3 to 3.5 hours.
I have already repaired my phone using Sony pc companion and also did a factory reset as well but this issue has been haunting me every now and then.
Sony center says the battery doesnt need any replacement as its still healthy and so is my device.
The phones service menu also reports battery status as Good.
I dont know when is Lollipop gonna be out for Z3 but I fear updating to Lollipop as it may pose more issues than doing any good apart from usual gui tweaks & updates.
But just wish that lollipop brings in more relief to Z3 batteries.
It would be better if you also posted some screenshots with your battery usage.

EVERYTHING drains battery, literally everything. If your volume is on max it also drains more then when your volume is very low. (Just an example)
There is a controversy when it comes to WiFi vs 3G which drains more.
In the end I think that it depends on the coverage. For me 3G/4G drains my battery less then my WiFi due to the poor WiFi reception.
That your phone loses about 5% over night really isn't THAT bad, what I do before I go to bed is "Close all" to close all the aps running in the background (It won't terminate WhatsApp's service) and I let Greenify hibernate all programs that I selected.
There was also a talk about charging your phone to 100% vs 99% the first percentage drains fast for everyone so that's why it's maybe better to only charge it till 99%.
With screenshots of your battery usage we could help you more, but as far as I can see there is nothing wrong with your battery.
If you're rooted, try BetterBatteryStats to pinpoint the drain.

Well my device isnt rooted nor I use any wifi.
And also I use Greenify to shutdown all apps before sleeping and also I do manual force stop for many other apps as well.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Moto Z Force's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
Drained like crazy
Got my Z Force yesterday and decided to test standby over night. What I got was 25% drain from 100 in 8 hours. The standby drain was cell standby. I'm hoping it will settle down but that's not good.

My cell standby is very low. Hopefully yours settles down.
Mine is very low as well. Even with low signal, I'm only dropping 30% or so throughout the course of a day with mild use.
Im getting around 5% drain while sleeping. Typically 5 hours a night so roughly 1% an hour
Be sure to turn wifi scanning off in "Location" - it appears to really drain and can end up keeping your phone awake. My first few days I had really bad drain but turning that off and some days with and without the mod and it has really settled.
Also be sure to close all your apps...that does make a difference as well.
5% drain here too. Approx 7 hours sleep. WiFi and cell active, with nothing deactivated.
Set your phone to disable WiFi when sleeping:
Settings -> WiFi -> Advanced "Keep Wi-Fi on during sleep" = "Only When Plugged In"
I was experiencing similar drain overnight (approx 20%) and this brought it down to about 3%
You can also selectively disable mobile data usage for apps in the background using the application manager. Recommend doing this for anything that might be a data hog or that you really don't want updating when your phone is asleep (e.g. twitter or other social media apps, if you don't care about notifications):
App Info -> App Data Usage -> Restrict App Background Data ON
These settings made a huge difference for me. Most apps are conservative about mobile data use by default (e.g. spotify isn't going to sync huge things over mobile while your phone is sleeping) -- I haven't noticed any particular increase in data use since doing this, but the battery savings is remarkable. Wifi is a big power drain.
Something causes the phone to not go to sleep sometimes. I have Greenify set up with Doze on the Go turned on. After a while, the sleep function just stops working and the phone has to be rebooted to get it to go back into the sleep mode. Haven't been able to figure this one out. Root would help us here.
Periodic rebooting does seem to help with standby drain.
Coming from an S7e, this phone is tops in this regard. Overnight I lose 10% at most. Almost always at 50%+ after work (7a-5p). Lenovo/Moto did it again! Just as happy as I was with the Turbo. Plus the chop chop works so much better, only ~5% fail rate. Fingerprint reader is much more useful than I ever imagined.

Omg I always wondered why the heck my phone always said WiFi battery usage was high even when I was on Airplane mode with my S5!
Thanks bro! ✌?

I had this problem too until I realized that I was using the fingerprint sensor to turn the device off. Greenify has an option for this, but it doesn't seem to work with the Z Force. Greenify does work properly for me if I use the power button to turn the screen off. But it doesn't if I use the fingerprint sensor.
It's normal to Motorola. This is a fresh factory reset.

Battery drain with WiFi and Data turned on simultaneously

I Have notice that battery of note 8 drains quickly when switches for both WiFi and Data are turned on.
I turn both on for the purpose that when I am out of range of WiFi, data will turn on seamlessly, and when WiFi is available, it will switch back to it.
With both switches on, even when only WiFi is in use, the battery seems to drain quickly.
Battery life is tremendously improved when only WiFi or data Switch is on.
Any ideas as to what is the problem?
Main element to drain battery after screen is Device Idle.
Attachment: idea as to what I am talking about.

If you leave the WiFi enabled all the time. Your device will constantly scan for a network, which you are signed onto. That drains the battery. Unfortunately you need to disbaled WiFi connectivity when you are not gonna use it to preserve power.
You can disable mobile data connection while you are connected to WiFi. This is done throw developer options
