Hey guys,
been using my X10 for a while now (2 weeks) and the battery life is one thing that tilts me a lot... I tried all the tas killer, adv task killer, task panel lite etc, and none really worked
also, juice defender just somehow seems to screw up my wifi settings. I use no 3g/ data at all so i just keep that disabled.
However from reading this forum I downloaded an app called Spare Parts. It is really good in that it tells me what is using my battery in a detailed manner. so it tells me that my battery is being drained from
Running 12%
Wifi running 12%
wifi on 99.9%!!!
Now i made sure of all my wifi settings, I have it turned to "Sleep when screen turns off" in the android menu, and "android default" under spare parts.
I uninstalled juice defender bc i found that it was just screwing up my settings, it kept changing the "Sleep when screen turns off" to "Never" which resulted in more battery drain
I dont know why my wifi is running 99.9% but i gotta think that is killing my battery.. The really annoying thing is if I goto the battery use under normal android settings and it is telling me wifi only used up 6% of my battery since last charge?
sorry for the mega long first post but any help is really appreciated
bumppppp! Im sure this must be a problem for other people too who don't know their wifi is running 100%?
Not sure what advice i can offer you mate.
Although WIFI is definately a large drain on the battery i found the source of my battery problems were down to having the "Location source and & Data use settings" enabled.
Put simply it will try to use either your wifi or data connection to determine your current location. If this is left running in the background it will seriously affect your battery.
Its better to only enable them when required.
Hi - The answer is in your question...
Wifi running 12%
wifi on 99.9%!!!
This means that your wifi is switched on for 99.9% of the time which you phone has been on, but it has only been "active" or "not sleeping" for 12% of the time.. This is fine..
I removed Ulitmate juice a while ago, but reinstalled only the Juicedefender element last week and it's definitely making a difference to my battery life - especially when I'm out and about..
Have a good look through the power usage thread - there's loads of stuff the phone does in the background that you can switch off to save juice.
Yea definately know what you mean, the only thing thats bugging me is that i am 100% sure my wifi settings were... sleep when screen turns off... so for wifi to be on 99.9%??? Shouldnt that setting ensure the widi is not on when the screen is off?
So, yesterday I noticed a sudden battery drain on my nexus 4. After checking battery it showed that AndroidOS takes over about 50% of the battery usage. It also showed that time awake was pretty much the same as the amount of time since I unplugged the phone, even though I kept my phone in sleep mode for the most of the day. After some research I downloaded better battery stats and it showed that from the moment I turn the screen off a process called suspend_backoff runs pretty much the entire time. Eventually I got it down to wifi. If I turn off wifi there are no processes running after the screen is turned off (or if there are they are 30 seconds tops), but the moment I turn wifi on suspend_backoff runs pretty much the entire time screen is off. I tried removing all of my apps, as well as doing factory reset but nothing helps. The moment I turn wifi ON this suspend_backoff consumes pretty much all the time during screen off period. Is anyone experiencing anything like this ? I have 4.2.2 on the phone and I havent' seen this extreme drain until just yesterday.
I experience the samething. Android OS would drain as much as the screen time.
I narrowed it down to the suspend_backoff. But the weird thing is that when i'm at home on my home wifi, suspend_backoff doesn't seem to drain anything at all. But when I'm at school, suspend_backoff kicks in.
Anyone help?

how did you narrow it down? Im having the same problem!
This is caused by a kernel wakelock. A bad mobile connection make battery drain worse... using WLAN nearly fixes this problem.
Thought this problem has got fixed in 4.2.2, at least battery life got improved and the wakelock reduced.
If it is appearing since yesterday, it is triggered by a app often waking the phone up using mobile data (that's why fixed with WLAN) and prevent the phone from getting into deep sleep as fast as it should.
hope i could help.
I use Greenify to hibernate every single user installed apps, then I release them one by one to see which one cause suspend backoff. But suspend backoff still occurs. So I think it's the kernel itself.

as i said before, an app needs data, so it starts callung the kernel wakelock... this one causes tje drain, not the app itself

Yeah, definitely not user apps. I did full reset on the phone to factory settings, no user apps. Even tried disabling Google Play and Google store after the reset. Still the same. The only thing that gets rid of it is disabling WiFi.

When did you start noticing this ? Has it been for a while or just recently ? I first noticed it yesterday (had the phone for a bit over a month now, didn't see any issues until just yesterday)

What is the difference between greenify and limit background apps in developers options?

Yeah, it's clear that it's the wakelock. What's not clear is why. Also it's not the msm_hsic_host that the forum link you sent refers to. I don't have a problem with msm_hsic, that one barely takes any time during the day (maybe 30 seconds during several hours of standby). The wakelock causing this particular issue is "suspend_backoff" wakelock which supposedly happens when there is a sequence of sleep/wake calls too close together so the system decides to keep it awake. I was unable to find what exactly is causing the issue, even after restoring to the factory settings I kept seeing the same problem.
Anyway, I was able to "resolve" it by installing JuiceGuard app and setting it so it disables wifi when the screen is off. wakelock is gone now and my battery usage is back to normal.
I only get the suspend backoff wake lock when I'm connected to the university Wifi. When I'm at home, everything is fine, no suspend backoff. So my guess is that the Wifi encryption at university is different and causing a succession of close "awake" and cause wake lock.
I did factory reset like 3 times and it still there.
I'll try disable Wifi on Monday and see how it goes.
Same here, when wifi disabled the wakelock doesn't occur.
I have tried almost all of the kernels and non of them seem to help.

Interesting... Maybe it is encryption. One thing with my Wifi is that it doesn't use password, but MAC list instead. It may indeed be an issue with different wifi encryption types.
OP do you have maps 6.14 on your phone? Mine kept switching on location reporting for a while and it woke my phone 344 times last night. I've been struggling with the same wake lock issues. I'm going to recharge (again) with maps disabled and see if that helps.

Check your Google account sync settings... In settings
The clowns may have left you a lovely gift there without telling you or asking any kind of permission.
The latest Maps was giving me horrible battery drain, on WiFi. I'd sleep for six hours with a fully charged phone and wake up with 10% left. it even enabled itself when. I disabled it in settings. I converted it to a user app by moving it to /data/app and greenified it. Seemed to have solved all of my issues with the suspend back off wake lock.

For some weird reason, I was also having serious battery drain suddenly since yesterday.
Turned out it was maps, and disabling Google network locations hugely increased battery life

I've had my N4 since the day it was released and the battery has been generally acceptable.....until I upgraded to 4.3 (stock, rooted).
BetterBatteryStats is indicating the suspend_backoff wakelock is rampant. WakelockDetector is showing I'm only getting 20% deep sleep on days I'm only lightly using my phone. On Android's Battery screen "Android OS" is listed as the top culprit, consuming 40% or more of the total battery.
Google/XDA searches indicate suspend_backoff is related to Chrome, but I'm convinced this is somehow a wifi connectivity problem as this wakelock ONLY happens when connected to my work wifi. On the weekends when not working my battery is fine and I don't see suspend_backoff. If I don't connect to my work wifi while at work suspend_backoff does not show up at all and I'm deep sleeping at 80%.
Unfortunately at work I don't have the capability of configuring/swapping wifi hardware/settings, so I'm limited to finding a solution on my end. Hopefully the solution isn't to have to sit on mobile data all day long instead of connecting to my work wifi.
Any suggestions?

In Settings, Wifi, Advanced Settings turn Network notification and Scanning always available off and see if it helps. Drainage can also be an issue when the Wifi signal is weak, but it can be Google Now! related among other things, Now! likes to give you fresh cards like traffic, news, nearby things and weather, turning Now! off entirely (voice search still works) could still be help. Also using other apps than Google. I know, hardly a real soluton but I replaced as many as I can.
No, wifi scanning is irrelevant since OP wants to use wifi.
What radio are you on OP? I'm assuming .84?
Yep, .84 radio, Google Now is disabled
Anybody?
rom kernel info? screenshots of the issue?
Back in the Galaxy S II days it was related to Google Chrome with the tilt scrolling. I always disable it though.
Sent from my Nexus 4 using Tapatalk
I am experiencing the same issue starting from yesterday, God knows why. The most common advice is to disable tilt-scrolling in Chrome but as far as I could see the Development Tools option has been removed from teh settings. Any other ideas?
could it be because you're using Touch Control for S2W or D2W?
Your work's wifi may have a combination of 2.4 and 5 GHz signals. I would get this wakelock if I allowed android to choose automatically which band to connect to, but if I forced either 2.4 or 5, the wakelock would let up.
Lookas a kernel bug, which has been fixed in teh latest Franco's release.
For a month or more I'm facing totally unexplainable battery drain.
As seen on the screens below, the phone is awake, but it is not detected anywhere - not by android nor by GSam. In any case the battery draws faster.
I have one observation tho - this happens after I make phone calls. Not every time, but once per 2,3 days.
Any ideas?

You have this problem
http://forum.xda-developers.com/note-4/general/explanation-horrible-note-4-battery-t3004274
I'm pretty sure that I don't have this issue. Yes, the percentage in GSam maybe high, but I don't believe this reflects what is happening.
First of all - I don't have bad battery life. Usually my over night drain is less than 1%/1h.
Second - the issue appears sporadically.
Third - in the provided thread I don't see the issue appearing in stock battery monitor, while mine appear.
At last - my battery drains faster only while the issue is present and before I restart. After that it is back to normal ...
@Spo0f
Just some suggestions maybe you're using 3g I always have that turned off and switch it on when I use it my guess is that some apps are causing your drain after a call maybe like you said if you're not fimiliar with greenify I suggest you use it to stop all those apps and system apps also uninstall all those bloatware you don't need or at least freeze them if you don't mind lower the resolution to 1080p with nomone app use power save or disable dvfs and use an app to lower and raise the CPU to save juice when not needed....
Thanks for the suggestions, but as I said - this problem appear sporadically - home when using WiFi as well as outside when using 3G.
All of the rest is done - I'm no newby

Oh sorry mate well I don't use much 3g so I can't help you there but if you're having drainage when you're using WiFi in general then maybe you should reconsider investigating the post above with the link I don't have so much drainage on connectivity with 3g or WiFi....viewing the pics you uploaded it seems suspicious.... Maybe an app? I don't know...
Use wakelock detector

My overnight drain was also very low, but that was because the faulty device on the network was asleep at night too (my desktop).
If you're not rooted, use the PC version of Wakelock Detector at the end of your day and post screenshots of your highest drainers for the various categories. In my case, the device was being woken up by something on the network and it showed.
Bear in mind that actively downloading something in the time period will also raise wifi power used but more stats will help.
The fact that you're still experiencing a lot of drain even when outside suggests it might be a rogue app
One phone call today and after it the phone stayed awake.
Because I had issue with the PC WLD the screen shots are from 11 minutes after one of the disconnects. The device was awake all of them.

I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.
Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".
So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)
The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.
Hey guys...
Just here to say that I unplugged this phone at around 5 in the morning, and around 5 hours later its already down to 74%.
What did I do? Only about 10 minutes of mobile hotspot, a 2 minute phone call, and three text messages. The rest just idling...
1/4th of my battery life for just that?
What the heck?
Everything is disabled and the screen brightness is low... Whats the matter with this phone?
Looks like something is keeping your device awake.
Can you please add some screenshots of your battery graph?
In addition, you can try to boot into safe mode. If your problem is gone in safe mode, a third party app is interfering.
If you're rooted, try installing Wakelock detector or BBS (Better Battery Stats) and check out what is waking up your device.
If you use Gas Buddy, it was known to be causing massive bluetooth wakelocks. Either uninstall it or update it to the latest version.
Set your wifi to 2.4 ghz only. On 6.0 and 6.0.1, the 5 ghz band has been causing abnormal battery drain and keeping phones from entering doze mode. Here's the issue being reported: https://code.google.com/p/android/issues/detail?id=197460
If neither of these make a big improvement, you'll have to use your battery stats (and if rooted, use Better Battery Stats or Wakelock Detector) to specifically see what's keeping the phone awake. In either of these apps, filter the view by "Alarms" or "wakeup triggers" and you'll see what the heavy hitters are.
Be sure to go into Location>Settings and turn off wifi and bluetooth scanning.
Hi.the maps app isvuding WiFi and gps even though both are disabled and I'm not using it... Any ideas?
