Hey
I am still on Marshmallow waiting for the Nougat update. Coz of battery lasting issues, I had just formatted my phone and did a factory reset. But today I can see that the phone is constantly awake! What app or method can I use to figure out the reason for this? I have installed Greenify to help me out, based on the Google searches.
Bluetooth is off all the time. Wifi is also in the on-demand state only.
Please help
My phone was being kept awake by the wifi range extender. There could be something in your wifi network keeping phone awake. Generate a bug report and run an analysis using battery historian tool.

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.

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.
Recently my note 3's wifi won't turn off while asleep. Under battery usage it shows that the wifi is on the entire time. The android os also shows as being on for more than an hour (it's also the top app on battery usage). It's lead to a battery drain. Using wake lock detector and bbs I haven't seen any app that is causing the problem. I haven't changed any setting either. The wifi is set to never be on during sleep periods. I remember seeing a post with a problem about this but I can't seem to find it anymore. I really don't feel like resetting back to factory settings. Anyone experience this or know what's causing it.
Huge battery drain when tablet is "sleeping" - probably because "bluesleep"
Hello,
I have problem on my N7 with large battery drain.
I had this issue witch Stock ROM, now I tried to root stock ROM (4.4.4) and install Greenify, but battery still dies after 2 days of no usage.
I tried to charge it fully, reboot it, cleared cache and dalvik cache, and put it to "sleep". After one night, 40% of battery was gone.
It seems that my N7 is not going to "deep sleep" for some reason.
So I tried to install numerous of apps to find what app is responsible for this. None was successfull, until I tried BBS.
In attachment, you can find BBS dumpfile. But it seems, there is some "bluesleep" kernel wakelock, which is responsible for all my troubles. Unfortunatelly, I dont know what this process is. Or am I reading dumpfile wrong and some other app/process is responsible for this huge battery drain?
I also attached screenshot from standard android battery statictics, which shows, that "Android OS" is preventing tablet from sleep.
Is there some way to fix this issue? Tablet worked normally for 1.5 year, but in last months is unusable, because it has dead battery everytime I want to use it.
Thanks for advices.
I would imagine bluesleep wakelock is related to bluetooth. Do you have BT on and/or connected to anything using BT?
If so try turning it off and see if it persists.
Yes, I use Bluetooth for my Jawbone UP24 sync. But I have this band only for a week. Extreme battery drain already was there before I have got UP24. In these times I had bluetooth turned off all time. So I dont think this is main reason.
I turned off BT. Lets see what happens in the morning.
UPDATE: You were right. It is bluetooth. When I turn it off, tablet is most time in deep sleep.
So probably rooting and installing greenify worked, but in meantime, I started using UP24 and Bluetooth on tablet.
I will try if situation is better with some AOSP based ROM. I did not wanted to flash another rom (than Stock), but I guess, there is no other way. Even clean Android on Nexus device is not usable with comfort...
I'm running stock/rooted kitkat and for the last few days I have had dramatic battery drain. I go from fully changed to 10% in less than 4 hours. Has anyone else noticed this lately?
I had this as well. I had to disable location services to get my phone to actually go to sleep.

disabling location services and trying that. thanks
I've had awful battery since i upgraded to 5.0 and Google services are killing the battery. I'll try location services. Will update.
It's definitely not a problem with Location Services. My location is completely turned off 99% (since always) of the time and I also have that topping my battery consumption. Even though, my phone has been deep sleeping without major problems. There's an unknown wakelock that is slowly draining the battery, but anyway I've been getting 4h of SOT everyday without making any sacrifices. If somebody finds out what's the root cause, keep me posted, please.
I've been occasionally getting this for a few weeks too.
If I turn off location, the problem continues for a day or so but then goes away.
This morning I took the phone off charger first thing. I restarted and didn't open screen for two hours. When I checked battery usage it was down 80% and the big consumer was Media and SDcard. Anyone see this before?
It just occurred to me that I may have a corrupt file on internal storage. I'm going to back everything up and start deleting.
Well..I did a factory reset and I still have a major battery drain. It has to be some rogue app but I haven't installed "new" apps lately. Plenty of updates though.
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?
