[Q] high android system battery usage problem related to wifi? - Verizon Samsung Galaxy S 4

Hi - Let me start of by saying I'm new to smartphones. The Galaxy S4 is my first one. Also, if I'm not posting in the right place, just let me know! Anyhow, for a while now, I've been having a problem with the "Android System" battery usage. It will be fine for a while, but then all of a sudden, it will spike up to really high levels that I know aren't right. For instance, after 12 hours after charging, with the android system around 3% or so, all of a sudden it will jump up to the 40s, 50s or even higher percentages. I would say that these spikes happen on average every 12 hours, but can be more or less frequent, though never more than a day. I've done a lot of searching around online about this, and it seems to be a fairly common problem. However, I don't really see any real solutions other than one that involves something called gsiff_daemon. I don't think that this is the cause of my problem though because when I click on "show CPU usage", it never shows up as an active process. I asked a friend of mine who is pretty knowledgeable about Android phones, and he suggested turning off the wifi for a while and see if it happens. Well I turned off my wifi and for 6 straight days the Android System never spiked. Within a few hours after I turned it back on, it spiked. (By the way, I also tried this with GPS, but it jumped high with the GPS off too.) My friend then suggested that maybe it's happening because it's constantly scanning for a wifi signal, so he said try unchecking "network notification" in the advanced menu of the wifi section. However, it appears that this option is not on Verizon S4 phones, even though it is on other provider's S4s! So at this point, we're at a loss. I want to add that I I think most of this excessive android system usage is not a true battery drain because it's impossible for it to go up so fast (within minutes) if you've already used 50% of your battery, for example. However, I do think there is a slight increase in the battery usage when this happens because it seems that way according to the info coming from the GSAM Battery Monitor that I have installed (but I don't know if that's always reliable either). I also have Better Battery Stats, and I can provide any wavelock info or anything else that might be helpful. I think I may just have to do a factory rest, but any help would be great!!

I was about to suggest a factory reset but it seems you're already considering that option... how strong is the connection to your router? If you aren't getting a good signal that could be a cause. Try to increase the signal strength of your antennas, if possible.
Have you taken the new OTA update? It's possible the new radio in the update may resolve your issue.

As it turns on, I actually got the update message about the new software this morning and installed it this afternoon. So far so good. We'll see if any spikes still occur. I thought this was the Android 4.3 update at first, but then realized that it was just a Verizon thing.
I do have a weak wifi connection at my apartment as I'm using some open free wifi in the area. But actually maybe there's something there about that that could be causing all this. This wifi connection is really weird where sometimes even though it says it's connected with a decent enough signal, the data connection is just a trickle and essentially dead and then I have to turn it off and use the regular mobile data.

Well it lasted 24 hours after the software update, but yet again, I got another spike in Android System. Maybe I'll call Verizon before I do a factory reset to see if they can be of any assistance, but I'm pretty sure they won't be, and it'll end being a waste of time and energy. However, they should know that this is happening frequently. There are probably a lot more people with this problem, but they don't even look at their battery meter to see. There's got to be a solution to this. I'm afraid though that even if I do a factory reset, it will happen again.

I just want to add that the spike happened with the wifi turned off. In fact, it often seems to spike (as it did today) as I'm driving home from work with the wifi off.

Is the "WiFi on During sleeping" Checked? Also have you tried another router? 2.4ghz or 5ghz?

I have it checked that the wifi is never on during sleep. It seemed to me to make sense to conserve the battery. Do you think it should always be on? I don't know anything about routers to be honest.

Check this
try this out...
go to settings-> connections-> wifi -> advanced (left select button) -> uncheck- " scanning always available" .
it has to work...

There is no "scanning always available" option on my phone. Maybe this is another thing that Verizon changes from other carries with the S4.
Anyhow, I discovered something a couple days ago. This may be a new "phenomenon" (lol), but now whenever I have my wifi on and I turn it off, Android System surges. When I turn it back it back on, it stops. But like clockwork, once I turn it off, it spikes once again. lol This is crazy. I'm just going to do a factory reset. I went to a Verizon store yesterday to have them look at it, and the girl there said they've never seen anything like this and that I should do a factory reset. If that doesn't work, then they'll give me a new phone. So a least I know that there is light at the end of the tunnel! lol I told her though that all you have to do is google "android system battery drain", and a whole bunch of stuff will pop up.

Enable Always on Mobile Data - Problem...

Hi all,
I seem to be having a problem with the Enable Always On Mobile Data setting. From my understanding (and certainly what happened in my previous ROM) is that if this is unchecked when the screen was off/phone not in use the G/3G/H connection was disconnected and you could see this when you turned the phone back on and it took a few seconds for the connection to be made.
Since installing VillainRom 10.3 and the latest Modaco rom this is not happening. Whenever the phone is switched on from standby the connection is still on. I have checked the awake time incase something is stopping the phone from sleeping but it seems fine. I have also been through all my apps and checked sync settings to make sure nothing is keeping the connection active but it shouldnt be.
As I have got this on two different roms I am pretty sure its not an isolated case and others must have experienced the same. Has anyone had this problem and is there a fix?
Thanks,
Michael

In my expiriences with Wifi it turns it off when the phone is asleep but the icon still remains for me at least so my guess would be it's the same for 3G etc. And it isn't like it's a huge battery drainer unless you have a weak signal
YAY! Post nr. 100 Senior member
Yeah, I think its 15 mins for WiFi but have tried leaving it for 3G and its still connected. Difference in Battery is quite substantial to be honest (weak signal area). ~3 days compared to 1 day

Hmm that sucks then... Will tell you if I find a solution There's probably an app for it
cheers, Juicedefender does a similar thing but will be another app running, using battery itself. Bit of a pain, especially when I know android cando this by itself. Anyone else having this issue?

Battery Status showing me as without signal 99% of the time.

I have had my SGS2 for just over a week now, I have noticed something odd.
if i go to Settings>about Phone>Battery usage>Cell Standby It shows "time without a signal" to be very high compared to the actual figures, some days it says 100% which I know is not true as I have been receiving email notifications etc.
the strange thing is, that i have definitely had signal most of the time as I have been using actively using the phone.
My actual time without a signal should read about 10-15% as I travel on the Underground to go to university most week days.
I haven't noticed any other problems, just seems a strange reading.
any one else had this problem?
Thanks in advanced, Mark
If you go to Settings, About phone, Status, it'll start showing it correctly from then on, until reboot.

do you know of a permanent fix?

Jellybeans wifi/battery drain workaround.

I make it short:
Yeah another wifi/ battery thread. But the only one with an actual solution for pi poor battery life after 21 update. Some people reported it helped also with the sod.
Wifi sucks battery dead.
Some people let all sorts of juice sucking bat-control apps running to find out that stock app reading is not lying: The bloody wifi never turns off even set to do so in the settings and just kills the battery of the device.
If this is your workaround you owe me a thanks . If you are an Asus employee testing poor battery issue give me credits in the fixing OTA by repairing the 'never' settings:
Go to
settings, w-lan,advanced (click on the three dots in the upper right corner, there it is), keep_wifi_on_during_sleep:
Instead of setting it to 'never', set it to 'only when plugged in'.
Now put your machine in sleep, wake it after 30min or even much less and BOOOOOOM! here we go:
You will see in the battery settings, that your wifi just has stopped pausing. Depending on how long ago the battery cycle has started you will see two shorter bricks instead of a long one as before. While waking your machine concentrate on the battery icon and you will notice the wifi-icon popping up just a second after you have woken the screen.
Of course this works also with shorter breaks but I'm not sure what is the shortest interval. Longer sleep period opens the gap in between two wifi-sessions wider. So this makes the working proof easier visible for the eye.
Sort of really a shame that Asus, Google and Nvidia have hybrid, wrongly programmed and even forgotten settings in their setup. (see my thread about the multitasking of the HTC1X http://forum.xda-developers.com/showthread.php?t=1599214 Maybe helps your multitasking issue.
But as we know, nobody is perfect .... except for xda!!
And then, many report, they don't have this problem at all. Very strange that not everybody is affected by this blind setting.
If this solution doesn't help your device,I am sorry for you. Maybe you have to stick to the bat-control app and learn how to read it, or RMA your device.
Did the job for me.
So I am ready for summer to join in, got enough juice for the IPS+ screen to stun the sun the whole day lun . Rock'n Roll
Edit 121002:
JellyBeans workaround as well.
Edit 120616:
Thank you Asus that the .28 firmware makes my workaround obsolet. Now get rid of this arm5 coding and let the bugger run !!
Edit 2:
Title changed from 'Asus you owe me a blowjob' to something less attractive for trolls.
Should be an obvious solution for everyone. But took me a hell of time to use the next best (second) obvious setting for my w-lan and get the battery saving.
Edit:
Please don't abuse my thread to flame, blame or mob your boss, retailer, dog or whomever. Only confirmation or non-confirmations welcome. If you find another or better or additional solution in the future or the past please feel free to post it. I did not have the time yet to check for the actual amount of powersafe but regarding my normal readings we are gaining the whole lost lot back and don't need to throttle down or ruin our eyes. I reckon the bat is gonna be better because now some of the ASUS optimisation hits some ground.
If you want me to fled off, I have stolen your ideas or you are an ASUS employee with no job-offer, don't PM me.
Thanks
I have been using this setting for a while and while I do get better battery life using the "when plugged in" setting than the newer "disconnect during sleep" setting, in general battery life is still worse in .21 than in previous builds and for me WiFi alone still accounts for more than 60% of my average battery usage according to the battery settings menu. For all of my other Android devices the screen is the largest single user of battery.
It does not happen to everyone. I have it on "never" and as soon as i click the power button, wifi turns off... if i wake the tablet right away (2 or 3 seconds later), i see the wifi reappearing and reconecting. So, for me, the wifi turns off instantly.
In the battery graph my wifi line is nonexistant whenever the tablet is sleeping.
I believe the wifi options are implemented correctly (sort of). But for some reason, it doesnt seem to work for some users.
Another way to save battery is to increase the wifi scanning interval... but that is for when you are using wifi.
I guess, for those experiencing the battery drain, it may be a good temporary workaround to use the solution mentioned by the OP.

another way to MAKE SURE you save battery is turn the darn thing off and shutdown and then when you need it's ready to go. I been doing this more recently and it defeats the purpose of tablet, but hey, when i need to use it, after the boot up its on. not trying to be funny.
Let's not get carried away. While a good suggestion it's far from a real solution for all the people that are encountering this issue. It's kind of like suggesting just turning off your tablet when your not using it to prevent battery drain.

Auto flight mode
I always install an auto flight mode program that will turn off the wifi when the screen turns off since most widgets prevents the system from turning it off and going into deep sleep.

Your way takes far too much time for me to act spontaneous. With my changed settings it's doing it automatically again, just as was intended the 'never' setting. Unless you charge the tablet by cord, the wifi turns off while you put the tablet asleep. I say settings are messed up.

Thanks guys for the the exchange, keep on rowing fellas ..
ill be the first one to Thank the OP as no one has. At least he is trying to help and find a solution. Even if it was something already known for the longest time. Sorry if the humor wasn't funny to you. Maybe he didn't know people already knew about this. which is totally fair.
to the OP, have you noticed that when you put wifi to stay on only when plugged in, when in sleep, that it takes a little while for wifi to come back online? meaning if you use the setting you said, then put the prime to sleep unplugged, then wake it back up, wifi doesn't connect back immediately. it takes a few seconds to come back online. that's the only thing I personally don't like about it.

yeah but personally this means to me it's working correctly. For the wifi to come back on instantly it would have to keep a connection and just not transfer data, when in deep sleep it completely turns off the wifi radio. When you wake it back up the radio turns back on, and it needs to connect to the AP all over again. This means the wifi was in a deep sleep (actually turned off the tab is in deep sleep) and it is working correctly.
I really wonder why every thread in this forum sooner or later becomes a trolling/flaming thread....
So guys, as usual (*sigh*) please stay on topic.
Trolling and flaming won't be tolerated but will be rewarded by other gifts like infractions and bans.
@OP: You might think about stoping posting in red: It usually implies a high rate of aggressivity towards other members.
Even if this might not be actually true in your case, other members still might missunderstand you.
On topic: This "fix" is really known since like, dunno, Froyo times? At least this setting is there already for ages.
Apart from that it should be obvious that turning off the Wifi drains less power.
However, you had good intentions so don't destroy them by flaming other members.
If you feel attacked by any post, just report it (obviously this goes for all members)
Thanks for clearing up, Diamondback,
What has been known since Froyo x.x is still worth mentioning. Many user have just started their android career because nowadays the hardware and the software are worth it. And once in a while talking about an old known tip is worthwhile especially since nobody else did.
@ demandarin ;-)
Edit on topic (referring to Diamondback):
This was no flame.
Asus shoot themselves in the foot, some people in my thread the same!
Obviously both the feet and so I call trolls by name,
themselves they should blame.
Right? Obviously not, which is a shame.
My only wrong the color of which I was ignorant,
shame on me!
I will change the teasing thread title
from Asus gets busted in Asus will get the game
I've been using this option since day 1. The problem is not that the wifi doesn't sleep. It's more so that it sucks way too much power when it is on.
I have an iPad2 3g as well which I received as a birthday gift so I kept it and with wifi and 3g always on, I still get 5-7 days of use.
On the Prime its dead under 2 days if always on and 3-4 days if off when asleep.
So it's most likely an optimization issue or driver issue.
Maybe the transmit power should go to low when asleep rather than staying strong.
Who knows. Regardless this can be fixed by Asus if they really look into it.

Actually the iPad has it's SW architecture on the plus side. I think the high battery drain on the TFP (and/or Android in general) is also strongly linked to the number of apps synching in background.
Maybe it can be fixed with drivers. Lowering transmit power sounds good. Could be that Asus optimized to much for the folks complaining about wifi performance....
The setting to turn off wifi while the tablet sleeps makes no sense for my use case. I mean for a wifi only device, it makes not much sense to turn it's connection to the outside off. How will I then receive notifications on gtalk, mail and so on? If I would like to safe power that way, I rather turn it completely off.
For a phone with 3g / edge data connection it might make sense. This applies for the 3g iPad as well.
I agree, it got a bit worse with .21 but for me battery life is still awesome.
Thanks anyway for bringing it to the mind of new users. Although I wouldn't call this a fix but a workaround.

Yes, I agree about the drain but isn't it probably because of the stylish casing! So nothing we can change there, but Asus could clock it down while asleep as you suggest.

My iPad2 goes ding ding ding all night. Lots of apps syncing. 3 email accounts. CNN app, and multiple other apps.
But I think iOS uses a very low power state for background sync while in sleep compared to Android.

Not sure if it's relevant because this was posted for the GS2 but it could also help with wifi drain on the prime.
from this thread: http://forum.xda-developers.com/showpost.php?p=25876666&postcount=3
"FAQ
Q: Wakelocks "wlan_rx_wake" wake up my device constantly what I can do about it?
A: The problem is neither Android nor the kernel, but the router and the (Windows7) network. In the network properties, uncheck "IPv6", disable the service "IP Helper", "Shell Hardware Detection" and "Windows Media Player Network Sharing Service", which provide ongoing Traffic. Then they scored again 98% of deep sleep."
And how you disable ipv6 on your phone/tablet is with a script but the value in the file gets recreated everytime you turn wifi on and off. So if you disable ipv6 then turn wifi off, then back on, ipv6 will be enabled again. I got around this by a tasker profile that will run every time my tablet connects to a wifi network. So it disables ipv6 right away again. You could do this in an init.d script(or in sysctl) as well but then you have the issue of it resetting itself if you turn wifi off/on
If you have tasker create a new profile for when wifi is connected, then run a shell script task, and check run as root. This is the command echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
to enable it just replace the 1 with a 0. You can also run the command in a terminal window if you just want to test it. I did it for my phone, and I just set it for my prime so I'll see if it drains less battery with it off..

I would just like to say thanks and let you know that I had SOD problems on my prime (as bad as up to once every day in frequency) for a very long time since .21 came out, after trying your work around (several weeks ago) ever since I have not had a single SOD sleep of death issue whatsoever.
I always suspected it was dock recharging causing the SOD fault but maybe it was a bum wifi stack or something, so thank you very much my tab is much more stable because the suggestion you've shared with me.
Unfortunately it does not help any flickering or GPU bugs I tend to get on occasion. I truly hate .21 it is so god awful for GPU, SOD and storage I/O.
I should just man up and downgrade but meh, sif i have the time do it
But yeah, thanks heaps, your workaround is an awesome suggestion.

I know it was disconnected because then I got 2 emails and gtalk messages that SHOULD HAVE come trough and notified me half hour prior.
I've been messing with the wifi sleep and power settings ever since, sending myself chat requests to test. it seems 20 minutes is the cutoff time before wifi drops to one bar or disconnects. this is a problem as chat messages should be pushed instantly, not when it gets around to reconnecting itself.
I've tried all different "yes no"options under keep wifi awake, power, etc etc and it seems 20 minutes either disconnects wifi or goes into some low-power wifi that is too weak to get push notifications. it seems to me it checks once every half hour for notifications if "never keep wifi from sleeping" is checked. again, this is a HUGE problem for things like chat programs, fring, anything that uses internet to communicate and not the 3g network.
again,I wasn't having thus problem for the last 2 days till I woke up this morning. This phone isn't getting secret background updates is it?? it still would need to tell me it downloaded and ask if I want to install, right??
me thinks this has to do with network scanning, for lte, as there is no connect or stay connected options for lte,I assume its gonna auto connect and disconnect to save battery like the thunderbolt did. I think its auto low-powering the wireless chip too except 3g in the same manner, unless never disconnect wifi during sleep is checked, and then it just turns it on and off. well,I have one of those weak internal-antenna routers so when it goes low-power, it can't stay connected of or moves or someone walks between me and the router. its a big problem to get chat notifications and Skype calls half hour later than they were sent because my phone is in done kind of auto-power-saving mode. I've spent the last 4 hours messing with this issue.
someone help!!
This morning my WiFi was connected without having to turn WiFi off/on again. I checked the other thread mentioned and my 'Keep Wi-Fi on during sleep' option is already set to 'Always'. I haven't rooted my phone yet so everything is stock.
For me it will show WiFi at the top as if it is connected but I try to do anything online and it won't work till I turn it off/on again. At that point I will receive any old notifications too.
I know for sure it's not my router because my Galaxy Tab continues to work just fine. I also have 3 computers connected to the WiFi with no issues.
Going to try a few more things and fiddle with the 'Best Wi-Fi Performance' option as well even though my signal shows full.
HTC!!!!! its always two steps forward, one step back!! something happened to my phone overnight because now connectivity is just jacked after the phone goes into sleep mode. no new apps installed
its true! the one X forums have way more relevant info than the evo forums have. they have a fix for this, but you have to be rooted. i also found this, which works for our evo:

How to access the hidden power save menu
Mine seems to not be staying connected when I let the phone sleep for a while. No problems while I am using it or signal dumping just when it's sleeping. I have my settings set to never. Annoying, hopefully fixed with a software update.
After setting the best wifi performance option on it seems that my notifications and wifi work better. Not sure how much this drains the battery though since I am at my desk with it charging most the time.

I've had this happen to me a few times. Even with 3g actually. Anyone else experiencing 3g disconnects/reconnects?

This started happening to me yesterday, as well as the phone rebooting when it attempts to connect to Veriz -- err, roaming data. I've also had the issue where I had to toggle WiFi to get it to connect to an AP again; these issues used to happen to my OG EVO way back when, so this has to be some sloppy software change management on HTC's part. My EVO's going back to Sprint; I don't pay to beta test.
I already posted in the other thread, but will say this.
Please call sprint and voice your issue. If/when they have enough complaints, someone at htc will look into it and it will hopefully be part of the next update.
Btw, I think one of the triggers is no wifi activity. If you're getting push email every 45-60 min, then wifi remains on. If not, then it shuts off after about an hour.
The hidden power settings applies only to when the battery is low (25 or 15% remaining). Either way, it doesn't fix the problem.
Notch another one with this issue.
I had the issue even when I turned on my phone for the first time. I connected to the wifi during setup and couldn't activate my dropbox because of lack of connection.
Once I got through setup, I turned off wifi, turned it on and it worked again.
But there has been a few other times, especially when I first enter a wifi spot, I need to turn off and turn on.
It is quite annoying. And like somebody else said, there is no way of knowing this until you try something.
this seriously is a huge problem. google voice calls don't come through, emails don't come, anything internet connection. once you on off it,I had 8 missed calls, ten work emails, etc etc. plus if it thinks its connected, shows the wifi bar, but not actually connected, it fubars your 3g data connection for a few minutes trying to connect to something. I am furious about this as I didn't have this problem my first two days with this beautiful phone. now I'm seeing the ugly side, and I don't like it. and I'm not rooted yet so I can't fix it!!!!
the google voice phone calls do NOT come through, and this is a major major problem. wtf was htc thinking??
I wonder if a suitable work around might be to use some wifi keep alive widget running that pings the router every 30-60 minutes...?
I'm not sure, someone more knowledgeable will have to let us know. I imagine it won't without being a huge battery drain. shouldn't auto sync do that anyway? I'll look and try later tonight if don't hear from any experts
I'm not sure what autosync is? I use k9 mail setup with imap/push.

[THEORY] Bluetooth(off) draining battery ?

Hi
I lately noticed that my S10 (G973F on ASH1) battery drain was noticeably higher when using bluetooth and that the drain continues even if I turn off the bluetooth (no, wifi and bluetooth scanning are not enabled). The only way to return to "normal" drain is to reboot the phone with bluetooth off and to not enable it at all.
I did some durability tests the past days with 2 scenarios:
1. Unplug the phone in the morning charged at 100%, ensure the bluetooth is off, reboot the phone and use it the whole day without touching the bluetooth
2. Unplug the phone in the morning charged at 100%, turn on bluetooth, optionally connect to a device, turn off bluetooth, and use the phone the whole day without touching the bluetooth.
My results are (with same usage, apps, conditions...) :
Scenario 1 : Average 8h SOT / 15h uptime
Scenario 2 : Average 5h30 SOT / 15h uptime
I know this is far from being scientific, that's why I call it just a theory. It's up to you to confirm or deny it ...
I totally believe it. The super interesting part to me is that turning it off doesn't affect the battery drain.
I certainly would love to know the reason why that is. Personally i haven't noticed the same thing (atleast as badly).
There's a lot of variables so I'm going to throw out a few theories/guesses (in order of my best to worst guess)
- it has to do with what kind of device you're connecting to... Probably a device that wakes up a background service of some sort (that doesn't ever sleep properly, so most likely a Samsung system service) is it something like a Samsung gear device or Galaxy buds? Anything Samsung?
- I know you already mentioned device scanning is off, i assume you're referring to the Samsung setting, but there are device scanning settings tucked away in the Google settings.
- some rogue app is glitching in the background, it sees Bluetooth is on, so keeps trying to peak at what's going on and scan for beacons or something like that. Best guess is Facebook. But it could be many others.
All in all, its almost certainly not Bluetooth itself, but rather something that's too active in the background and keeps trying to sneak a look at Bluetooth connections.
Install better battery stats, run the adb commands to set up for non-root. That should tell you what's waking your phone so often.

Your analysis is pretty logical and I fully agree with it.
I already tried BBS (rooted) and got no convincing results (nearly the same kernel wakelocks, partial wakelocks, etc).
I also sent to samsung a bug report with the dumps and logs needed and should be soon contacted by them for further collaboration if needed.
But while waiting, it will be really a good thing if more users could test the two scenarios I mentioned and post their feedback.
Hey, First thank you for the knowledge. I will try to do that and will give feedback

I posted your idea in a German Android forum. Maybe there are some testers.

Great idea. Thx :good:
Hey,
sorry your theory is not true.
On the screenshots:
"Ohne BT" meens i restarted the phone in the morning and dont use bluetooth.
"Mit BT" meens i used bluetooth for streaming for some minutes.

That's a very well done experimentation ! It's the first case contradicting the theory.
I should have done some similar screenshots before updating to latest ASH6 on which I am unable to reproduce the "bug" ...
But there are very many rely on bluetooth. In the car, smartwatch, etc
