Battery - Wi-Fi and Awake always solid blue

So I've been trying to get more life out of my battery, I get decent now, but not the 18+ hours I've seen other people getting. I think the main problem here is, if I go view the Applications -> Battery Usage screen, the "Wi-Fi" and "Awake" bars are always full blue, even when the phone hasn't been touched in a couple hours.
Does anyone know what actually causes these to now sleep? Is it push email? Or some other setting I'm missing?
Thanks

Look and find out you can start by turning off wifi if not using it post your screen shots of battery use someone may help

Try Menu/Settings/Wireless and Network/Wi-Fi Settings. Then press Menu/Advanced/Wi-Fi- sleep policy.
Play with those settings. You are probably set to "Never". Folks have actually been reporting better battery life with this setting (powering on and shutting down the wifi eats up battery) You can play around with it to get your own results.
Hit thanks if this helps!

Ah...yes, it is set to never. So leaving it on "never" gets better results, say if you're at home and always have a wifi connection? Also, if the wi-fi is on, does that mean the device can't sleep I take it, that's what's keeping the device awake with screen off?
Thanks for the tip.

I've heard both sides to this argument, and frankly I don't think most people understand why changing it does, or in other cases does not help.
I suspect that the answer to your issue isn't going to be found here. Here's the theory:
- Setting wifi policy to "Sleep - Never" results in better battery life for some; it's likely because these individuals have a fairly low 3g signal, which tends to draw more battery when periodic updates/synchronization occurs (e.g., gmail, calendar, facebook, etc.). By leaving wifi Sleep set to never, the wifi (which THEORETICALLY uses less power than 3g) can do the work instead.
- Setting wifi policy to "Sleep - When Screen is Off" can result in better battery life for a number of reasons, many of the underlying issues being hard to identify. For example, if your router tends to send a lot of 'noise' and wake up your phone, having wi-fi disabled will prevent this. Location services in the OS - which you've probably permitted to 'help locate you faster' - even when you are NOT connected to a wifi network - will periodically ping wireless networks around you to help facilitate faster geolocation. This uses battery as well.
But don't confuse the generalities that have spawned from people's anecdotal situations with what could be a very different problem.
Was your phone primarily located in one location during most of the 'awake' period? If so, then it was probably connected to the same router most of that time. If so, it really shouldn't matter what the setting was for Advanced Wifi - the phone should still sleep.
If you turn off wi-fi on the device, and the device then sleeps, then you've narrowed the issue some, but that is not a solution, because what are you going to do, not use wifi?
You've got to dig deeper; your issue may be any of the following - rogue app that keeps a wakelock, rogue app that updates too frequently, wifi modem issue, router issue, OS issue, etc.
In short, you need to figure out what's keeping the phone awake. Get CPU Spy and Better Battery Stats to help you get insight into what's keeping the device awake.

Thank you for that very informative post. My phone was on my desk all day today( worked from home ) and wi-fi is set to always on, and it never slept, not even once.
I'll try disabling wi-fi( should have done this earlier to be honest and checked ) and then I'll download those apps, I just got Badass Battery Monitor, I'll check out the two you recommended as well. Thanks for the info!

Your phone should still go into deep sleep with wifi on. If it doesn't then you have something else wakelocking your phone. However, if wifi is set to never sleep, and wifi is enabled, the bar on the battery chart will always be solid blue.

So just installed CPU Spy, it looks like IM+ is the biggest user of wakelocks. I like to always be signed in to my accounts, but not at such a huge cost of battery, does anyone know of a better multi IM client that will push updates to you? I used to have IM+ on the iPhone( yea I know, just switched two months ago, and never looking back ) and the push on it worked great. The 'push' IM+ says it has is awful, most of the time I never get my IMs sent to me at all.
Also have skype signed on all the time, not sure if that is wakelock'ing anything, I'll have to keep an eye on it, it didn't show up on CPU Spy.

Try IMO, free from the Android Market. Its a multi-IM client that combines most common clients including Skype. I've used it. It creates some wakelocks, but not sufficient to wake the phone. I don't use IM very often so I'd be curious to hear how it works for you.

So been trying IMO the past couple days. Seems much better than IM+. Haven't seen any disconnects, I get my IMs about 30sec - 1min after the computer gets them, which is fine, and the wake-locking is extremely minimal. IM+ was awful with the wake-locking.
So that clears up the Always awake issue, flashed Blazer 3.8 last night, so can't comment on battery too much yet, also calibrating today.

Thanks for the feedback, glad to hear it helped, and I now feel a little more confident leaving my IM 'on' more often.

[Q] What's best? Wifi Off when screen is off or Wifi on all of the time?

To start off with; i get good battery life; right now I'm at 1 day 3 hours and I have 39% left.
I was wondering however, does setting the Wifi to go off when the screen is off help significantly on the battery? And if so...is there some other negative issue that I'm not aware of if I set it this way?

I'm pretty sure any sort of data connection will use more of your battery than WiFi will. So if you're always around a strong WiFi connection you probably should leave it on at all times.

Oh that is funny.
I just do everything everyone else does:
1.) Screen off when not in use
2.) Screen brightness down as much as possible.
3.) Dark theme.
4.) Tasker profiles to turn off wifi when not near my house or work.
5.) Tasker profile to turn off GPS when not actively using certain apps.
6.) Tasker profile to turn off BT when not connected.
I also am probably a light user...the only thing that I do beyond normal phone use is to watch Netflix a slight bit a day and stream Spotify a bit.
I also don't play games except Words with friends.
No FB no locations, no nothing like that.

Wifi off and data off would be most helping when screen off

13% is ODD. Something is sucking up your battery.
Expand your Android system and post the Screenshot - want to look at cpu wake time.
What is your setting under - Advanced Wifi options - while asleep - wifi on or off ?

To be honest I have done so many tweaks to help with wakelocks. It is definately not an app but the standby time is sooo much worse on my Note in comparision to my HTC One S. I'll get about a day regardless of screen time. On my One S I'll get 2 days with the same screen time and with the same apps.
The only thing I can think of it being is that mdm_hsic kernel wakelock. Have no clue what to do about that though, and it's clearly a Samsung/Note 2 bug given that the HTC doesn't have this sucking away the standby time.

Do you have ebay app installed?
Try uninstalling and see if this makes a difference. The ebay process/service constantly runs in background even tho its disabled in app settings and doesn't show battery usage.
I had same problem and found that its to blame!

The thing is, I also have the ebay app on my HTC and it doesn't suffer from this problem. The HTC is 4.1.1 though so I'm guessing this is either a Samsung problem or a 4.1.2 problem.

hi,just a few pointers to think about ....?
i am on stock 4.1.2 not rooted ,and my avarage battery drain overnight (10/11 hrs +) is 2%..or ..3 %.
i also have a note8.0 and battery drain is normally 1% in standby mode overnight (10/11 hrs )also on 4.1.2
lucky ? no i don't think so .
(maybe i got my all "tweaks " right..no ?)
just a few pointers (things to think about, why others get better results and others not,in this case on 4.1.2 )
good luck

Do you have any Battery manager apps installed? I had one that constantly pulled WiFi status and since I have WiFi disabled when outside of home or work it kept on turning it on/off and drained my battery. It was my error for configuring it wrongly, I admit but still, that may happen without control.
Check Wakelock Detector, click on this:
Awake.............................Statistics since..............................Deep sleep
bar after night of rest and post statistics that you find there, The most interesting is a difference between Screen-on and awake times. If your phone is awake much longer than it has it's screen on then there are some processes that keep it awake and drain battery.

WiFi by itself will not eat battery, something has to use it to create this drain. How do you have your wifi configured?

Wifi does seem to be messed up on this phone. I find, on standby, it causes more drain than 3G does. Usually something like 10% - 15% overnight.
This is not right and something is seriously a miss with Samsung. My HTC running the exact same apps does not have this problem. You shouldn't have to turn wifi off as opposed to 3G to get better battery life.

Are you thinking about some hardware problem that causes wifi to use more memory than usual? Like higher voltage or something? Because that is not very probable. I think there is some app there that is using wifi, high power usage happens when wifi is performing scans is being turned on or actively transmiting data. Please use wakelog detector to find what app is causing kernel wakelocks and from there we can find a real culprit.
I does not have to be malicious but may be an incompatibility between hardware and some software, one that works well on HTC and not on this Samsung model.

No I don't think it's hardware.
I also don't think it is an app given what I have observed with wakelocks and deep sleep. I have made many adjustments to the phone and I'm clued up with wakelocks and the like and this doesn't seem to be a wakelock issue.
I have even assigned a static ip and made tweaks within my router but it hasn't helped. There seems to be a strange way this phone handles wifi and it is causing unnecessary drain.
In regards to Kernel wakelocks, it would appear something called mdm_hsic is causing lots of wakeups and more standby drain than it should be and this does not feature at all on my HTC. This is not related to wifi, but I'm pinning the general crappy standy drain im getting on this but there doesn't seem to be a way to get rid of it.

mdm_hsic is related to Modem part, you may try different modems (be mindfull of efs problem in newer firmwares), also try to enable/disable "fast dormancy". I think you could test that by selecting "GSM only" and observing.

I have tried different radios in the past. If that's what you mean?
I've also tested around with fast dormancy (it is currently disabled)
My network only works on 3G and has no 2G coverage. It is purely a 3G network and therefore GSM only will not work. This problem still persisted when I was on a different network though and selected gsm only fornthe majority of the time.

Yes, I was talking about radios.
Have you ever tried changing CSC file? Full, four part flash in Odin, not only PDA?
What method did you use for modifying fast dormancy setting? Because the correct one includes full factory reset when changing CSC. Anyway fast dormancy would be a problem only if you used 3G network for data.

Nope have not tried changing the CSC.
The method I used for fastdormancy was with that app in the marketplace than allows you to toggle it on and off. I'm not sure if fastdormancy is linked the mdm_hsic though, to be honest.

Battery usage much higher on 3G than WiFi

Hi,
Have you guys noticed our phones tend to drain battery much much faster on 3G than WiFi? I have yet to measure the drains accurately yet but I think the difference is huge. I can drain the entire battery in 2-3 hours with data on and active data transfer.
For example, stream some music on TuneIn on wifi and then on data (3G/H+). On data, the phone gets really hot and sometimes even with an AC charger plugged in the battery can barely hold charge (with screen also on). On Wi-Fi the phone stays cool and battery consumption seems to be much less.
I feel like it's ok for data to use a bit more power but I feel like this much of a difference is not normal. I have WCDMA preferred in mobile options, and it is displaying H+ in the status bar. I am assuming it isn't using LTE or looking for an LTE signal... How can I make sure of this? Is the LTE a different radio/chip that can be turned off separately?
I'm on CM10.1.2 with Wind Kernel 2.5.

what do u think requires more power receiving a signal from 30 meters away or a cell phone tower
having said that if your rom is pulling more than usual from data connection you can try switching to cdma only mode, also i think the stronger signal you are getting the less power it uses but im not sure on that, i think if u are in a basement or something it will pull more power.
or try switching roms
it is not the "phone" unless your phone is defective
try a differant rom if that doesn't work try a differant baseband if that doesn't work phone is probly defective or partially defective
first thing is try a stock based rom
btw i think the only time wifi will take more power than 3g/4g data is if you are sending huge amounts of data over it or have it on constantly scanning for networks, or have a rom that makes wifi stay on fullspeed while sleeping

No I haven't, I kind of just assumed it had to be normal. The phone gets hot just like when you're talking on the phone for a while so I thought it made sense.
I have some preliminary numbers (didn't let the test run long). If you want to replicate this, get Android System Tuner, and set up a widget to show "Average mA since last measure". Turn brightness to minimum and set the display to not turn off, start streaming TuneIn radio, unplug the phone (to reset "last measure), and let the battery go down at least 5%.
-360mA - wifi on streaming music, screen low brightness (20%/hour)
-760mA - 3g on streaming music, screen low brightness (note that's 41.5%/hour!)
-400mA - 3g on streaming music, screen off (22%/hour)
These preliminary numbers would suggest WiFi uses almost nothing, since the screen seems to be about 360mA, whereas the difference between WiFi and data is 400mA!

ive never had to flash my own baseband everywhere i read people say only do it if you have issues and ive never had issues, the rom/kernel i'm using is in my sig
there is a baseband archive in the developement section if it comes down to trying differant basebands although i'm not the person to talk to about that as i've never done it, i'm sure if you end up doing that asking on that thread would be your best bet as you will probably get responses from people who have done it before.
here i'll even link it:
basebands
this is a last resort and be very careful when flashing these

if it was me before i bothered with any of this i would have redownloaded and wipe/reflash rom, i just had my phone streaming music on 3g and it didn't even get warm
i don't mind helping you but please rule out the easy obvious steps first

Yeah I would have to second that, those mA are way too high. I am @ < 100 mA on H+ streaming off slacker now that is with stock, but when I was on cm10.1 I would have to say it was about the same. The ONLY time my phone gets warm is on GPS & charging, and my phone is over clocked to 1728 all the time.

Thanks. I've changed basebands before with packages from that thread. That's why I'm asking if flashing CM will override those.
What basebands are you guys on?

i'm honestly not sure if rom flashing changes baseband my gut instinct would be sometimes yes sometimes no but i'm honestly not sure, i dont even look at baseband unless i'm having problems with my radio signal and i never have.
ur problem is probly caused by you changing yours.
my baseband is: apq8060/mdm9200
have u tried what i suggested and flash a stock based rom to see if that fixes the error, then if you want to go back to cm10.1 u should be able to as long as you dont mess with basebands again
it's possible this doesn't fix the error if the stock rom doesn't flash a baseband, i'm honestly not sure if it will but it might
be careful that you don't flash one that reflashes a locked bootloader, most of the stock based roms on the developement forums have it disabled

Thanks, that's what I'll be trying today. I was on V20e (newest Bell one from that thread). Yesterday I tried V20c, V10j. All are pretty much the same in terms of power usage as I tested them yesterday. I will try a stock-ish ICS today and test there.
BTW, I tried the streaming test on a Nexus 4.
-550mA screen on lowest brightness streaming 3G (compared to -760mA for mine)
-360mA screen off streaming 3G (compared to -500mA for mine)
So the differences aren't THAT drastic, but still.

So here's some updates:
I flashed V20f mod V2 by HoNo (a stripped down and CWM flashable V20f stock image from Bell).
At first, I thought everything was fixed, as I was seeing battery use at about 500mA with screen on lowest brightness, streaming over 3G. However, I think this was due to the battery being low and the battery % dropping slower when it's under 15% (Android Tuner free uses battery % and battery capacity to estimate current draw).
I charged the phone overnight, then I flashed my CWM backup of CM10.1.2. The good thing is it kept the V20f baseband (and firmware) from flashing the V20f rom. That confirms that CM10.1.2 and CWM backups don't save/flash baseband.img and firmware.img. However, again, I was seeing 700+mA draw. There might be better idle usage with the new baseband, but it might be placebo.
I went back to a CWM restore of the V20f rom and tested again on the ICS-based stock-ish rom. Battery consumption is still high (700+mA streaming on data and screen on lowest brightness).
Could one of you guys please try running the same test I am? Here's how:
0) Ensure your battery is in the range of 50-90%
1) Download Android Tuner Free (AT)
2) Download TuneIn
3) Add a AT widget (1x1 text option) to a homescreen
4) Tap the widget, go to settings, widgets, widget content, central value, choose "avg mA since last measure"
5) Go back to AT settings, battery, calibration, battery capacity, enter 1830.
6) Start to stream music from a radiostation on TuneIn
7) Set screen timeout to 5 or 10min
8) Set brightness to minimum
9) Plug phone in
10) Unplug phone (this resets the "avg mA since last measure")
11) Watch the central value as your battery drops for 10-20minutes. Since drain is an estimate based on % dropping it will jump around a bit but level off the more time you let it run.
12) Don't do other stuff on the phone so you aren't using the CPU more than for this test

Battery drain, wifi not turning off?

I've noticed lately my battery life has plummeted. When I get to work, I turn off wifi, and even after very light use throughout the day, 9-10 hours later it will be giving me the low battery warning. I checked the Battery screen, and noticed the Wifi bar is solid blue the whole day as seen in the attached picture. If I am reading this screen correctly, wouldn't that be an indication that wifi is actually on all day? As you can also see in the screenshot, the wifi logo is not on at the top, showing I do in fact have it turned off. Do I have a problem? Does anyone else know about this issue and have a fix for it, if it is in fact a "issue"?

Go in to your WiFi settings, hit your menu button and hit advanced. Uncheck "always allow scanning"

Thanks, doing that this morning and will check the battery screen in a couple hours.

OK, that seems to have taken care of the wifi appearing to be on in the battery stats. I will wait until later today to determine if that was the cause of my battery draining quicker. I know there were a few new apps I installed around the same time, and I may have to start digging through those too.

Are u in an area that has low lte strength. If its switching between LTE and hspa+ that is tough on battery. Or location settings, or random apps running in the background. Grab BBS and see what is eating up the battery, wake locks apps etc. Their is am Xposed module that dispatches of wake locks if that is your issue. But I'm guessing its one of your apps or signal.

Actually, yes. When in my office, I get VERY low signal and it is constantly in HSPA. Also, what is the full name of BBS? I am not finding any kind of tool just searching play store for BBS.

Better battery stats is what you are looking for I believe.

Yup, found another battery thread on it. I downloaded it, but am not rooted, so not sure how helpful it will be. All the other data is greek to me on it, so someone have any pointers what to specifically look for?

Go in to your mobile network settings and change the network mode to wcdma/GSM instead of lte/wcdma/GSM if you're always switching between lte and 4g. Try that at least.

if possible grab WiFi at work, and use only that and I bet your battery significantly improves. then when u leave, hop back on normal data and see if that helps

Well, I've tried the setting the mode to not include lte, still getting pretty quick battery drain. There is no usable wifi here due to the level of security my facility enforces. Anything I can have BBS export to have you fine folks take a gander at and see if you find anything relevant?
