[SOLVED] Battery drain with data usage on vs. off

Hello peeps,
During the last couple of days I've read up a lot on the topic of battery drain. The reason is that a few weeks ago I could go for days without charging my phone with minimum usage with data traffic and gps turned on, display set to auto adjust the brightness etc. I basically didn't take any extreme ways to save my battery, as I simply didn't need to. But then I flashed Doc's and Stefunel's latest rom, with hardcore's kernel and all that. You know, pretty standard, nothing special. DTJP3 modem, the standard one for Australia. Was great for a start.
But then the horror began, after about a week. I've noticed that the up/download arrows are pretty much constantly glowing up there, and the battery drains in hours! I can't notice that my data usage have gone up a lot though. So I've tried that battery settings wipe thingy and some other stuff. Changed modem to JPY, which is also supposed to work in Australia (Even better from what I've heard). And sure, feels like I might have a bar or two better in reception. But the upload/download is still constantly on.
This is when I tried turning that of. I turned of data usage, gps, bluetooth, wifi, set brightness to lowest and downloaded Battery Snap. So with everything turned off, my battery dropped an average of ~0.5%/hour without usage. SWEET! Then I turned on data usage, and nothing more. It dropped 23% for the first hour, and 13 for the next half hour. Didn't think about actually checking the temp, but it was warm. Like when you use it.
This turned out to be an awful lot of text for just this question, but what could be the problem? Is there any way to check what's leaking? I've got SGS email on push only, no task killer, WiFi turned of, so those can't possibly be leaking, could it?

about 5% per hr here with data on, may be you got something in behind hog the cpu an keep sendibg data

Sounds like an app keeping data connection on. Try kill all apps, look on the services and kill the ones which are not nessesary.
I get ~ 1.5% per hour drain with mail sync every 30min with 3g on ...

Yes, 1-5% per hr is pretty much what I'm looking for, and had before. It's definitely not CPU, as I've got OSmonitor, and nothing shows up there as hogging it.
I'll try killing app after app through OSmonitor, thanks for that tip.
Oh, and btw, I turned data usage off during night. It has dropped 1% in 9 hours now

That was easy
com.seven.Z7.service is the villain here. Isn't that the SGS email client? Even though I have push? Thought that wouldn't be a problem then...

com.seven.Z7.service kept starting again, but the I went into "Settings -> Apps -> Manage Apps" and killed Social Hub. Voila! It worked. Even though I started Social Hub up again after, it worked. Weird... Or, not 100% sure yet, but so far it works. will check the battery drainage first in a few hours

Good have you have probably found it! One sidenote i have stopped using the sgs email client since i had the problem that new emails werent showing up ... i switched to k9 - you can try this if the problem stays ...

Oh, that might be an option. But, ye, we'll see if it works. If not, I'll consider K9
Thanks for helping me find the problem.

Had the same problem with my SGH-959d (Telus Fascinate). Tracked down the culprit with Droidwall and then found your post. Killed the process through manage apps like you did and same results. Pulling battery didn't work, changing sync settings either so thanks a million for this!

I had a similar problem with my battery graph nose diving. I only realised my data was going through the roof when I started getting 'your are using to much data' text from my operator.
What I found helped was going into Settings->Privacy and turn off 'Back up my data'
Now I get I can go a day without charge. Instead of and hour and a bit... would be interesting to know if it helps you?
(On XXJVO no mods)

good tip about back up... but what do we loose?

A nice tip could be turn 2g/3g on/off when need it. Its a good way of saving battery.

I too am curious as to what id lost if we turn off back up data

[SOLUTION] Found a fix for battery draining

This doesn't work. Ignore this thread please. Android OS and Wi-Fi Sharing reappeared after a few hours even though I was in bed sleeping and not using the phone.
For those who have problem with Android OS and Wi-Fi Sharing draining battery, this is for you.
I think I have found a solution. I need someone to try it out with me. So far so good. The main culprit is Kies Air. If you are not going to use it, please do not tap on that app at all. If you can, hide it. Once you tap it, it will remain running forever even if you shutdown and restart your phone. So what can we do?
First, Factory Reset the phone. Then, make sure you do not launch Kies Air after Factory Reset.
That's all. Now all you need to do is monitor the battery graph and let us all know your findings. You should not see Android OS, Android System high up in the list. Wi-Fi Sharing will no longer appear in the list that consumes battery.
I have success with this.

How long have you had it running like this?

why dont you just end the service in the settings?

I use Kies Air extensively. But it does not really keep running in the background here.
I dont keep my wifi on unless and until needed. SGS2 is very quick to get IP than my older phones, so i turn it on when needed from widget. Also you dont need wifi on before launching Kies Air. It will turn it on and off by itself.
when i close kies, it asks me if I want to disable wifi and it closes properly.
I tab of ATK and it closes on me never to turn back on by itself.
The only programs that keeps coming back are hubs and iplayer which to be honest does not seem to eat juice much. I will be getting rid of them soon enough.

now that i think of it the nexus one doesnt have kies air does it ? and it has the same android os issue?

Kies air shutdown wont help, did not even have it installed and still have android os bug

I've had both android os and wifi sharing eating battery, and I've never touched Kies. So it's not that.

not a soluton for me.. becuase i do occasionally use the wifi sharing so that i can tether over wifi.. the solution i am using which is kinda kludgy is to freeze the two wifi sharing apps with titanium backup (requires root).. works for me.. when i want to tether i will unfreeze them.. hopefully this will fix in a firmware update.

sorry guys I am late to the party.
WHAT AM I SUPPOSED to see for "Android OS" and "Android System"?
My phone right now is at 4 h 15 min (I charged it before going to bed, yes I sleep 4 hours a day). The phone did not do anything, but sounded Alarm to wake me up, and I had screen on for like 10 minutes total so far, plus the Alarm sounding and vibrating.
I have AOS at 37% up top, and AS at 3% on the bottom. This is not right?
I used Kies many times, but restarted the phone after the last time, and that was before the phone was charged last time.

my AOS is at 6% now - it was at 47% this morning... but i think that was because the screen was 0% whilst i was alseep, so yes your 37% is waaaay too high, mine was up at 15% but since i installed juice defender it has dropped to between 6-8%

Android OS / Android System percentages don't really matter that much - even if the device had a week long battery life, the percentages still have to add up to 100% - so something always has to be using battery.
The main problem seems to be the 'wifi sharing' and 'wifi sharing manager' services, which start up whenever you connect to wifi...

Out off sudden my watchdog task manager caught wifi sharing at 40%..
All these while will be only suspend, events/0 and android system. Both suspend and events/0 average on 35-40%.
Is this the reason my battery drain so much?

You mean you're connected to Kies Air and wanted to play with your phone while waiting for files being transfer? The answer is yes, press the home button and do whatever you want, it will not be disconnected.

Sorry, I meant when I finished and exit the program, something continues to run in the background (wifi share?) that drains the battery?

Damn...
Android OS @ 46% followed by Display at 21%. Android system however, at just 4%. Yeah 46 is just way too high...

Oh.. my watchdog didn't report any app misbehave after I done with Kies Air.
My wifi sharing will keep on running on background at 3% regardless of whether I connected to Kies or not. Frozen it but it still there. LOL. Weird.

Battery Drain from WiFi

I'm sure there are others who have experienced this problem. Even though I show no wake locks my phone drains at an unacceptable rate while on my Wifi at home. My phone can have a 60% battery when I go to bed, and be almost dead by the time I get up. The only clue that shows up in Android System Info or Spare Parts is network usage by '0' which is something with root access.
This is happening regardless of Rom. I've tried stock, Syndicate Frozen, Urban Fury, Bonsai, Stock Plus, and maybe another I'm forgetting. They all drain the crap out of my battery with wifi on at home so obviously this isn't a rom issue.
This leaves me to believe that either something on my network is forcing data to my phone keeping it from deep sleep, or the router itself is the cause. Turning on my phone to 3G, my battery life is spectacular overnight. It deep sleeps like it's had a case of beer with a bottle of nyquil as a chaser before bed. 1% an hour.
So, I've ordered a different router to see if that's the issue. I've googled my current router which is a D-Link DIR-655 and seems like others have had similar battery drains using that router but no one can emphatically say it for sure is the router. Guess we'll see when the new router arrives if it is indeed the DIR-655. Otherwise the next step is disconnecting everything else that is connected to my network (3 computers, 2 printers, XBox, Wii and a Blu-Ray player. I just wanted to point out to anyone else having issues with wifi and weird battery drain, that it may not be the phone that is the problem.

I too have massive battery drain when using Wifi. It doesn't matter what Wifi network I'm attached to (work/home/friends/etc), I burn about 10% + per hour on idle; whereas on 3G is burning only ~2%/hour on idle. On stock, Wifi was my battery saving grace.
I've just given up on using Wifi for daily use. I use 3G for everything now.
I hope the newest version of SFR (whatever the new one will be called) will remedy this problem I have. I haven't posted about it in the rom thread since I had a feeling it was just my phone or another bad flash in CWM.

I've been using that OS Monitor app to try and find the problem. On 3G all the network interfaces have static receive and send amounts as long as I'm not doing anything that requires data. Connected to my home wifi, there is a constant trickle of data.
When I let the phone sit overnight, there was over 4mb of data received, even if I turn off any kind of auto syncs on the phone.

wifi settings
Don't know if this will work for you but you can try. In the wifi settings click the menu button and select advanced then set the wifi to never sleep. I know it's counter intuitive but I went to sleep last night at 61% and woke to 57%. Wifi has been fine for me since changing that policy in the wifi advanced settings.

Mine has been set at never sleep since I got the Epic in September, and I double-check after each custom rom flash. Good looking out though.

Same here. Mines always been set to never sleep.
Edit: I just tested my phone on my work's wifi network. CPU Spy says it's going into deep sleep just fine. OS monitor shows a static data received/sent number once I was connected. Obviously something about my home network is the problem.

That is my general experience, too. These settings usually keep my WiFi usage low overnight.
But some nights, inexeplicably, I will wake up to find a large battery hit from WiFi. I don't think it is my WiFi router's problem, unless there is some outage duirng the night I am unaware of. Come to think of it, I had that problem last night but did not investigate early this morning before I left. When I get home, I will check with my laptop to make sure my router is running.

I have noticed this too and in particular over the past few days. I'm on the latest bonsai build which does have amazing battery life on 3G but now wifi does draithe battery much more than 3G. This never happened before. I have had my wifi set to never sleep. Any other suggestions?

Obviously haven't tested it overnight yet, but I shut down my one laptop and the constant data trickle immediately stopped. Right now it's looking like something my computer is running might be the culprit. Going to leave it sit overnight to see how it goes.

I found the cause of my drain! Narrowed it down to something from my laptop as when I shut my computer down at night, the drain would go away. The culprit was the HP Printer software for my wireless printer. Once I uninstalled it, the drain went away. Noticed in resource monitor that HPZinw12 was sending a constant stream of data from my computer. Why in the hell it would be also sending to my phone keeping it from sleeping seems pretty odd, but I recommend if anyone else who is having battery problems over wifi and happen to also have an HP printer, you might want to look into this as well.

I'd also add that my solution to getting rid of the problem and still being able to use my printer was just to uninstall the crappy HP software that came with the printer and add the printer through the control panel and let windows 7 install it. It doesn't throw on that HPZinw12 file that apparently polls the entire network constantly.

Since I have been experiencing similar symptoms intermittently and I also have a WiFi printer, I have tried to eliminate this as a potential cause. (I don't run an HP control app on my laptop, but already map the printer directly in Windows 7 like you suggest.)
In my case, I still get the excessive WiFi battery drain, and low battery level upon waking, sometimes overnight. But other nights the problem does not occur. So lately I have made sure that my laptop and printer are powered down before bedtime. And like you, a always have my WiFi sleep policy set to "never" and have a strong WiFi signal. But last night I still had the problem, and awoke to find the battery drained to 45 percent instad of its typical 90 percent.
Interestingly, I noticed not only high WiFi battery usage but also high "Cell standby" usage attributable to the well-known Time Without Signal problem -- and this despite my habitual use of the Airplane toggle workaround, which usually works.
Somehow, something caused both WiFi and cell radios to go crazy overnight.
BTW, I run a stock, unrooted Epic.

So far with SRF v1.1.1, my Wifi is back to normal.
On my work network, I've dropped 4% in 3.5hours with my work email syncing every 15mins. So that's pretty good usage given that sync interval.
I also do not have a printer at home, so the printer bit wouldn't have been a cause for me.

While the printer thing took care of the biggest problem for me, I still don't get as good of battery life overnight leaving my phone on WiFi rather than 3G. There is still something my computer is doing that wakes my phone up occasionally, but at least I'm not going to bed with a 70% battery then waking up to a dead phone. At least I have it narrowed down to one computer (total of 3 on my network), as when I shut that particular one down battery life for my phone is back to 1% an hour while sleeping. If I had to take a guess at this point, might be something with media sharing as I use that one as my primary location for music/videos to stream via Windows Media Center.

How do you know it is your computer? Have you tried just turning it all the way off?
Do you watch the services running on your phone? I routinely stop the DRM service, for example.
Except for the mysterious episodes when I experience this intermittent problem, my overnight battery usage is typically about 1 percent per hour.

I've tested over a few nights with a mostly full battery off the charger and reset the timer on CPU Spy. The nights I shut that computer completely off, I get very little battery drain and the phone is mostly in deep sleep according to CPU spy. When it's on, the phone shows a good chunk of CPU at 800mhz and more battery drain.

i have to say, the juice defender rocks, totally solve my battery problem.

actually, i still dont understand how it works. days before, i keep.complaining the bad battery, it drops 15% after one night. i turned my wifi and 3g off, it didnt work. i opened a thread to complain about this, some friend advise me to use the juice defender which really help a lot. now it use only 3 to 4% for 8 hours standby, which is much much better than before. if u are also troubled by ur battery, give it a shot. it's free from the market.

What does it shut off? Seems like it has to be something important to work. I want my email in real-time; does it mess with that?

I installed this only a few hours ago. yet to see any significant change. By the looks of it, having it on the default setting will turn data off when your screen is off, but I still get e-mail notifications in my 1hr check intervals even when my phone is sleeping.

The main feature is that it disables data most of the time (2g, 3G or wifi) and only enables it at preset intervals, like 2 minutes every 30 minutes to get your e-mails and stuff.
So basically what you lose is push / real time notifications.
It can also manage the screen brightness and CPU clock more precisely, put the phone in plane mode while you're sleeping (for example you can tell Juice defender to go in plane mode from 23:30 to 6:30 every day, except if you're still using your phone after 23:30 or start using it before 6:30), or activate wifi only when you're in a specific location.

Does anybody have issues receiving MMS picture messages with JD or any other power saving app running?
I had 'Green Power' running yesterday. A few people sent me pics which came through as blank. Stopped the app and asked them to resend and it worked.
Thanks

I tried this app too, but the battery draining when WiFi was enabled was higher than without JuiceDefender. Still trying to get through all the JD settings...

I dont think Juice Defender would work well for me as I use Whats App a lot...

I use it on my ego. One of the best apps i bought
from my phone duh

Is anyone else able to toggle the 2G/3G setting? I've paid for the Ultimate Pack (wish i hadn't now as the Plus pack is supposed to do this) but apparently JD doesn't like my ROM, the Log says: 'ROM is not compatible with AOSP helper (3G control is unavailable) - get CyanogenMod
Out of interest i was on a UK O2 branded phone so i flashed XEU KW7, then rooted, then put back the original KE7 kernel. I wonder if that's the problem?

I was messing with Juice defender, but I found the app called Battery Booster to be much, much more effective. I went from a 12 hour battery, to having between 24 and 28 hours the last 3 charges. Simply amazing, more than doubled my battery life. Using perhaps 1-2% per hour when sleeping.

1-2% per hour when sleeping is not that good, i get 3% in 8 hours when sleeping.
But juice defender does what should be built into the gingerbread and that is, it puts your wifi and 3g to sleep when your screen is off or when you are not using it.
I personaly dont use push notifications so loosing that doesnt bother me, what bothers me is when the phone is in sleep it drains because i have wifi on.
I dont want to be turning wifi on and off all the time, i want it to be automatic, when i go on the web or open an app that uses data it should turn on my wifi.
SO YES JUICE DEFENDER DOES ROCK.

Well, before battery booster it used 5 - 8% per hour sleeping, so I'm pretty darn happy with the results I'm getting now. It used to last me about 12 hours. Now it lasts usually over 24 hours, which is great. That is included with 3-4 hours of screen-on time. Android OS also dropped by 20% after getting battery booster.

no problem at all with push services.
the way juice def works is simple: it geolocalizes ur wifi router, and moving out the area of wifi, jd switches off wifi hardware until u come back home\office. it does the same with other hardware modules not in use.
wot doesnt work: ebuddy or other istant massaging apps while screen is off (I think it's unuseful to use jd with IM-draining batt-apps)

I just installed Battery Booster. Juice Defender didn't do much for me but annoy me.
Now see how this app will hold itself.

Very similar to my finding with ATK (link below). Something happened in Gingerbread with how the OS handles cached apps... to the point where some cached apps stay active and keep your device awake!

[Q] Phone doesn't go into deep sleep + wifi always stays on

This is very annoying, I have spent the whole morning trying to find a solution for this issue. The battery runs out already fast as it is, and now the phone is not
Battery drained about 20% at night by itself. Currently draining about 1-2% per 5 minutes when idle. What do I do? I have looked on various different threads for a solution, but did not find anything to fix this issue.
How do I fix this?
Thanks, in advance.

Also some details.
I had my phone at home, I prefer the phone to use WiFi networks when syncing and updating, but to have phone turn them automatically off when not using them, that is when the phone is locked and not syncing and updating anything. But apparently it doesn't do that, it has WiFi on at all times for some reason. And I don't know if its related to WiFi, it doesn't appear to go to "deep sleep"

For me, it was the last Google Maps update. Try to disable "Reporting Location" and "Location History" under Location settings on Google Settings app(the one with the green icon). I had around 25% drain over night and half of it came from this.
Try it and see if this can help you.
:fingers-crossed:

Like above say, disable location, especially if you keep wifi on.
Leaving wifi on while sleeping itself is not good for our health anyway, so if you have data switch to 2G, its at least enough to keep internet messages coming while saving battery. And if its wifi wise, apply pm.sleep_mode=1 in your build.prop. AND, scroll up a little, wifi_supplicant_can_interval(something like that, from its SHOULD BE 15 change to 300-600).
Disable unused apps and use greenify.

For me, it was the last Google Maps update. Try to disable "Reporting Location" and "Location History" under Location settings on Google Settings app(the one with the green icon). I had around 25% drain over night and half of it came from this.
Try it and see if this can help you.

Thank you for the answer, but sadly it didn't seem to do it. My WiFi is still always on, even though I have it set to turn off when phone is sleeping at WiFi advanced settings.
Although the phone entered deep sleep mode when I manually turned WiFi off, but I'm not sure if that was the case.

I understand, but I forgot to do so, I actually have an app that turns on air plane mode at certain time. But that still doesn't fix the issue that the phone doesn't enter sleep mode with WiFi on and doesn't turn it off, even though it's set to do so.
Also I did not quite understand what you were telling me there, as I got the phone last week and it's my first android phone. The app you suggested could cut it, but that means that whenever there will be an auto check for news sequence I will be downloading it with mobile data? Is there an app that could cause this?

I was about to update on this, but I just got notification about 4.3 update. :laugh:
I will update this post, if this problem still exists.
UPDATE : Of course, still the problem persists, Phone goes to sleep when I have Wi-Fi turned off. But when on, even though I have it set to turn off during sleep mode, it keeps the phone wake and drains the battery.

How is it related to my router exactly? My iPod disconnects from Wi-Fi no problem.
Thank you for trying though.

I had left my phone this night with Wi-Fi off, but mobile data and 3G was on, Lost 7% in 7Hours from 47%. Does this seem okay, or a little bit too much? By the time I answered 2 emails and made 1 short phonecall and checked on battery logs from 2 different apps, and changed my wallpaper, battery has dropped to 33%. I'm not proud.

The answer to your problem is JuiceDefender Ultimate, available from Play Store.

Unfortunately this is normal, the battery life is not the best feature of nexus 4. How many screen on time hours do you get averagely?

This fixed the Wifi always on issue for me.
Turn WiFi on: Settings, WiFi, Menu (3 dots upper right hand corner), advanced, uncheck scanning always on.
Hope this helps.
