My 8125 is suddenly running out of batteries very fast. I suspect this is because of some activity running - if I turn the unit off, and leave it on my desk overnight, it is exhausted by morning (I, on the other hand, am exhausted by morning only if I am turned on. Sorry.)
I have checked for:
alarms and notifcations that are set to go off - there seem to be none
mail and other internet access items - there seem to be none
programs (like SPB Weather) updating themselves too frequently - there seem to be none
My energy settings are normal; sleep in one minute, backlight down, etc.
Is there anything I'm missing? Any suggestions?
wifi, bluetooth. make sure they are turned off.
That's exactly, WiFi and BT even when active in standby really drain the battery quickly.
thanks so much, but.... Wifi and Bluetooth are off - I never turn Wifi on, and I almost always keep Bluetooth off (though I wish there was a way to quickly - or even automatically - turn it on or off, ie, whenever I use it in phone mode, BT would turn on, and when I hang up, it turns off.)
any other thoughts?
Battery Gone Bad
Hey I think your battery is gone bad.
BT Off
Wifi Off
Backlight Down
Sounds to me battery is ready to go to the recycle bin lol
Also check your MSN Msnger Is not onn all the time.

maybe it is the battery. the unit is less than a month old, but I just bought a spare battery. I'll compare run-down times on both.
a related question: why would WiFi and Bluetooth consume battery power if the unit is asleep?
-thanks-
I started getting horrible life out of my battery as of last month, but then I upgraded the ROM on it and have been getting FANTASTIC battery life. Better than when I first got the device.
which Rom did you upgrade to?
Summter <sp?> 2.3 for Cingular

Did you solve your battery problme?
when i am out in the country, where i might rarely get a signal, my battery drains real fast, prob to do with the constant searching for a signal to connect to.
I came upon this thread after my 8125 began having problems with the battery life last week. I'm wondering what kind of battery life people are getting and which settings they have.
For instance, before last week, I was getting little battery drainage during a 9 hour shift at work. Then this week, I was getting close to 55% battery drainage over the same duration. Just a few moments ago, I checked my battery settings and I found out that for some reason, my phone wasn't shut off after 2 minutes of idle time as it was originally set at. Okay, I'll test my battery usage tomorrow at work, but I suspect that was the problem.
Then it got me wondering how long other people have for battery life. With Bluetooth on, wifi off, lowest brightness setting and my auto shut off set at 2 minutes, I was able to last an entire 9 hour shift on standby with only about 4 - 5% drop in battery life. Hopefully, that is what I'll have tomorrow when I test it again with the auto shut off setting in place. What are others getting for battery life (please specify your settings).
I've forgotten to charge my phone at night before, and have had no problems making it through the second day of usage, though I'll usually get a low battery warning.
I keep Bluetooth and data connection on constantly. Don't use Wi-Fi unless I need something really quickly. Backlight is at the lowest active setting. I would say I use it moderately throughout the day. I use it to take important notes and make reminders for myself, along with surfing the internet without worry.
hi
Please check out activesync which drains the max battery..
make sure that activesync is not running in backround. once after disconnecting your mini-usb cable connectivity from PC please check for the activesync status.. if running turn it off.

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.

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.
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.

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.
I have come to the very certain realization of late that WiFi is using up all of my battery, and I am trying to figure out how/why. This trouble began when I updated my wireless network and essentially added an upstairs wireless repeater, or at least that is what I think. It seems to me now that I think on it that my battery troubles began soon after I added said repeater. Anyways, 2 nights ago I fell asleep around 1:30am after my shift ended at work. I had 100% charge and at 6:30 am 5 hours later when I woke up, with wireless off, I had 98%. This is what I was used to with my phone before. I proceeded to use my phone on and off throughout the day and at about 7pm I still had like 68% charge, which is great I then turned on my wireless to connect to home network and pull down a file. I went to bed early, and left wireless on throughout the night. My phone burned through more battery without me using it and just WiFi on than it did the entire 18 hour period before. I woke up with 15%. Here is what it looks like. Anyone have any idea what may be going on?
I have an Asus router that can also be configured to be either a repeater or an access point. I am now thinking I perhaps had it setup incorrectly. I set it up now as an access point with a different ssid from my downstairs router. Should not be too difficult to switch access points when upstairs or down. I half think it was bouncing between routers before when they had the same ssid, which was causing needless wifi useage. Here's hoping this helps.

Would it be possible for you to tap on the graph so we can see the breakdown of awake time/screen time/mobile network connection uptime, etc and show us that?
I just did this now. Does not coincide with my first screen shot. Also, not sure if I am reading this right. According to this, looks like my wifi was on all night, but I know for a fact I turned it off when I went to bed, which is why I only burned through like 4-5% during the night.

In the WiFi settings on your device, hit the menu button. It should bring up the option to pull up the advanced settings for wifi. It looks like the pic. If you turn off the scanning and smart network switches, that should help some.
The problem was definitely do to the fact that I had upstairs wifi configured as access point with identical ssid to downstairs. After changing that, I am now getting killer battery life. Close to 2 days on a charge.
Well, my problem went away or seemed to, but after installing BOC4 firmware 2 days back, they seem to have returned. Here is a screens hot of last night. I turned wifi off when I woke up around 4:30 as I noticed significant night time drain when phone was idle. I went out to play a gig last night around 5, and find it interesting how my problems got better while away form home, only to rerurn when i got back. Not sure what is going on with it.
Hi,
The Nexus 6P has been pretty good so far on battery. Nothing super insane, but enough to get me through a day.
Max I get is 3 hours SOT when I hit 0%...
Android OS is usually in the top 3, and in a 10 hour day, its getting 2 hours of Keep Awake time and about 30min Mobile Radio Active.
Google Play Services is also getting around 45min Mobile Radio Active as well.
Phone is bone stock, bootloader locked, unrooted. Running a handful of apps, even stopped using my Moto360 and disabled bluetooth when not in use to see if that was the culprit.
Any tips? (or apps that help me delve deeper into Android OS and why it keeps waking the thing up)
would also like to know about this, having very similar stats
Similar situation here - crazy battery drain and "Keep Awake" when I have a sim card in (TMo). 3 hours sitting on my desk - not using it - the phone gets warm/hot and Keep Awake shows 1H 16m under Android OS. When I put the same sim back into my Nexus 5 (using the adapter/converter) the N5 battery is perfectly fine.. normal.. no massive drain.
Any thoughts?
Turn off Wifi and give it a try. See if you still have the same battery drain.

Go into location & uncheck all scanning functions
Thanks. I should have mentioned that I already had wifi and bt turned off, and had turned off scanning for both under Locations. I was trying to isolate this to cell signal as best I could by disabling wifi and bt things. I also tried turning off "Enhanced LTE" - and now I'm trying it with wifi calling on (again just to narrow down different possibilities).
I think a factory reset is in my near future - may as well start from completely scratch and see if I still get the same horrible battery drain.
Just reporting back. I did a factory reset - and INITIALLY I thought I was on to something. Battery life seemed better at first, but then I soon began dropping cell signal - which apparently sends the phone off searching for signal chewing up battery.
In my case it's never ending cycle - get signal, drop, search, get signal, drop search.
Yes, I'm in a fairly weak TMo LTE service area, but my Nexus 5 and my wife's Nexus 4 have never had these sort of massive drain issues.
Also, I was in a major metro area on Sat night and the signal kept dropping as well. I couldn't toggle it back on via airplane mode or the mobile data switch. I finally had to reboot to bring it back - and then it proceeded to drop again. Meanwhile, my wife's N4 had no issues.
I went to TMo on Sunday and swapped out the sim - no change. 6P went from fully charged to completely dead overnight (roughly 1AM to 9AM).
So, at this point I'm wondering if I just have a faulty 6P. I'll be calling Google today to see about an RMA exchange :/

Maybe try activating band 12?
http://forum.xda-developers.com/nexus-6p/general/fastboot-activate-band-12-volte-t3239652
I found that my wifi network was causing doze to not work as good. I turned off wifi at night last night and got better results with just data.
My radio is accounting for 88% percent of my phones battery drain. I was down to 60 percent with about an hour of SoT. Not sure what's going on with my device either. I was about to factory reset but don't want to.
Bums me out when I see people getting 4+ hours. I want that action.
I had the mobile active bug also, very close to getting an iPhone.
I saw in another thread that apps like GasBuddy has been causing wake locks like you describe. The issue may be app related. Rooting and installing a battery monitor app should give you more insight as well as wiping and loading just your basic apps to find the culprit because something is definitely wrong.
I get 6 hr SOT without doing anything special and at night I lose 1%, sometimes none if I only sleep for 5hrs and that's with wifi on.
