Ridiculous battery drain on standby

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.

I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Sigh, I might just have a bad battery, or preferably poorly calibrated, since another hour of use, just browsing and such, and I'm down 20% more -_- hope I don't have to RMA again

As a side question.. how hot does your tablet get under normal use? Mine has been heating up quite a bit in the battery section i think with just average on browser use :/

Nothing you've mentioned sounds even the slightest bit out of the ordinary. I know a person who thinks they are always sick is a hypochondriac so is someone who always thinks there is something wrong with their computing device a hypo-com-driac?

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3

Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.

Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.

If your not using nfc that could save battery?

I used Better Battery Stats to figure out Google Maps was causing wakelocks. I cleared data in the maps app and now my 7 idles without much battery drain at all.

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...

Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.

Smb349 wakelock?

This kept my phone awake for an hour. Anyone know what this is?

Indeed. You can see this yourself within BBS (or other similar applications) by changed the point at which you wish to view statistics. For example, set it to list all events since the device was booted and it will show up. Now change this to only view events since the device was last unplugged off the charger. Now it's no longer there and since it's only happening while the device is charging, it's nothing to worry over.
I haven't researched what this service is though, but combined with the logic of what I started and what NervGaz said (awesome name the easy), I'm certain that it isn't having any ill effect on battery like all. I started monitoring battery consumption again street the OTA KitKat update because of several complaints I read about and was trying to help then out as MANY of them were suggesting just to do a factory reset and I had jump and say something because a factory reset is a drastic last measure attempt and quite honestly told them that a reset won't help a thing since they will go back to the same habits as before, meaning installing the same battery sucking applications (*cough* Facebook) or have apps such that set to sync all the time, etc.
Even if it was an issue brought on by a bad KitKat installation, the phone can always be fixed (with the knowledge i guess) without resorting to a factory reset. I've never had to perform one on my life, even now using my unrooted replacements G2. Never got around to rooting this one and also currently using apps which require me to remain unrooted. Now, being that I'm unrooted now, there could be the small chance of a system file getting corrupted etc that I wouldn't be able to fix, but if that happened I'd just root, fix the issue, and unroot.
Kind of went of track there, most likely due to the fact that performing a factory reset is always thrown around as the first step in trying to solve any issue on the phone. In rare cases like a corrupted file in a directory you can't access and you don't want to out can't root your phone, then yes. The Verizon telephone service people (I don't like giving them a title...some are very good at what they do but...we won't go there) are famously guilty for using resets the magic portion that cures all ailments.
Anyways, the point that I was trying to make before going on that rant was those posts on the other forum was what prompted me to investigate battery concerns, because from what I thought, KitKat was supposed to improve on battery consumption by (no clue the accuracy that numbers as I don't have an official source) up to 20%.
On KitKat I've been getting around 5-6 hours of battery life. So far I'm at 37% battery left, with 4 hours and 17 minutes since being unplugged with an estimated 1 hour and 57 minutes left. Doesn't sound very good does it for the average G2 does it? Not until you realize screen on time has been 4 hours and 6 minutes, with my main activities being surfing forums and typing a LOT as well as some time dedicated to my favorite mobile game at the moment which also happens to use more battery than ant other game I've played...Avabel Online (IgN is Styrael if anyone plays - lvl 64 gunslinger)
I haven't run across anything out of the ordinary yet when it comes to battery life but kids still early. Sorry for the long post there, I think I'll get back to Avabel. I hope the 100% exp, jexp (job experience), and drop rare bonuses are still in effect.

[Q] Question about rooting my Note 3 for better battery life

I've had an AT&T Note 3 since January. The phone is great but since the update to 4.4.2 I have been experience horrendous battery life, to the point that I'm having to charge it throughout the day.
I work construction and use my phone for several hours per day, resulting in 2-3 hours of voice calls and 2-3 hours of screen time. My last Note 2 and the current Note 3 used to be able to handle my workload while being unplugged from 7AM to 10PM at night.
If I was to root my phone, could I gain back my battery life? I have never had the need for my phone to be anything other than stock but I am desperate at this point.
Thanks

Rooting your phone will not result in having better battery life. What you can do is detect apps that keep your phone awake. Another method is to flash a custom kernel with lower voltage or one on which you can undervolt yourself. Be aware that by rooting and/or flashing custom recoverys/kernels or firmwares you'll trigger the Knox counter. This will void your warranty. There is no way to revert it.
Please use the Q&A section next time you have a question. Hope I could help you a little.

I appreciate the reply. I was hoping that rooting would allow the phone to run off of custom firmware and not have the horrible battery drain many Note 3 users are experiencing after the 4.4.2 update.
I have installed GSam Battery Monitor for over a month and been monitoring it daily. I'm consistently seeing Android System and Kernel (Android OS) using 40% of my daily battery life and Media using another 15%-25%. Other than that I've been unable to determine much else. I do not play games or Facebook, I just talk and text all day.
Is the warranty on the phone one year? If so, I'm 2/3 through it and would be willing to void it for better battery life.
I have looked through all I could find before posting, but honestly am somewhat overwhelmed by all the information on XDA. This is magnified by the fact that there are many versions of the Note 3 and different carriers.
I have a N900A Note 3 and am looking to get my all day battery life back and appreciate the help.

Don't worry, it's normal to suffer infoglut the first time looking through xda. You'll get used to it =)
So you have the AT&T version of the Note III aka hlteatt or SM-N900A. You're device has a Qualcomm chip built in like most of the Note III variants out there. There's also a Note III variant which has an Exynos chip built in but I think you won't confuse Exynos firmwares with those dedicated for Qualcomm variants. The ROM threads ususally have pretty good descriptions about that. AFAIK most custom ROMs are compatible with any Qualcomm variant. E.G. any AOSP/CM ROM for the Qualcomm Note III has a unified build carried by the name "hlte". Meaning, that as long as you don't flash an image meant for the Exynos variant, you should be good.
40% for Android-System and Kernel isn't normal at all. I also use GSam Battery Monitor. Android-System and Kernel only use about 19% of the battery on my phone. Something that helped me when I had the exact same issue was to switch locating method from high accuracy to power saving. You can find this setting by long-pressing the GPS icon in the notification drawer. The location settings menue will pop up. Under "Mode" you can change to "Power saving". I'd be happy if you could report if it did work for you.
You're welcome =) Just hit the thanks button.

If I may add my own comments here:
1. you should go to note 3 ATT forum and there find proper method to root your phone, we have towelroot program that can root phone very easily without breaking knox warranty, albeit I don't know if it works on your version, it worked perfectly on mine (t-mo)
2. While it is true that root by itself won't do anything about your battery usage, many programs that really help need root
For example greenify, titanium backup or android assistant require root to disable many useless (useless for you that is) programs that drain your battery
3. I totally disagree with Nitrous that GPS is the culprit for high battery usage. It is my experience that GPS all by itself does not work at all unless the location info is requested by some other programs. Google maps for example only run GPS when screen is on, when screen is off, GPS is off also. However some badly behaving programs can keep requesting location even in the middle of night, but IMO those programs are the problem, not GPS itself. I have GPS, BT and WiFi on 24/7 and with light use my phone could last 4-5 days. If GPS was draining battery as many people think, phone would never last that long.
What you should do is go to ATT forum and find towelroot method, root your phone and freeze, or disable apps you don't use. For example I don't use Bloomberg, Yahoo, Facebook, Hangouts, indexing etc (your list may be different, since different provider) so I have them frozen (won't start up) . If I ever change my mind, I can unfreeze them later.
You can also run programs to tell you which apps use most battery, or wake the phone from sleep and then decide if you need them or not.
BTW sometimes full reset and cache clear can fix some of the problems, so maybe that should be the first step.
Once you find which program /s cause problems your phone should last whole day. I could easily get 6 or more screen hours on my Note3, unless playing some intensive games, so should you and it just took couple hours to identify and disable all the bloat and there is a lot.
I also experienced increase in battery usage after updating to KK, but I have not found a time to look over the bloat and redo my program freezing efforts yet.

I know that GPS doesn't drain battery that much. But trust me, it is very likely to cause that type of behavior. I'm in this forums since a couple of years. In most cases, when Android-system and Kernel drain unusual amounts of battery it was location services that was causing it. But not because they were using GPS, but because they kept the device awake the whole time. And there you see my point of switching locating methods. In 90% of the scenarios where people described this kind of behavior of their devices, this solved the problem. But you're right in saying that it's not a permanent solution. I agree to your first two points.

I always have GPS off and only turn it on when I need it though Android still has the higher or second highest battery usage.

I agree, root and uninstall /freeze bloatware. You'll be surprised.

Just to give quick update, after I wrote my comments here, I fully charged my phone and went to sleep. In the morning battery was down to 80% and that finally prompted me to action. I freezed some apps, cleared cache and did some "housekeeping". I don't know what did the trick, but this time overnight my phone went from 100 to 98%, 10 times better than a night before. Now, after 18 hours of some light use like few calls, couple games, light internet use etc it is still at 80%, so it's pretty much back to what I had before update. I wish I wrote down what I did to track particular culprit in my case, but it is amazing how couple bad apps can ruin battery life, but at the same time killing them turns things around so much. All in all, out of some 340 apps and services on my phone, only 21 are frozen and about 30 are stopped from starting at boot up, but are able to start later if needed.

Terrible after 23.0.1.A.5.77 Update

I have just bought Xperia Z3 Compact 6 - 7 days ago.
Battery time was more than perfect.
BUT my phone asked me to install 23.0.1.A.5.77 Update.
After update, battery life is very very bad now.
I did a factory reset, but nothing has changed.
Still the same update. Still terrible battery time.
Thanks

You didn't ask a question so I presume you'd like to revert this update...?
If so, grab FlashTool, install its drivers, and find an FTF of an older update, then flash it. It does not void your warranty and it does not harm your device.

Same problem here, specially when the screen is off.
Something is draining 15% of the juice per night.
- Stamina Mode on
- 3g on
- Whatsapp, Pushbullet and Timely in the "exclusion list"

I had similar issues. Also with tap2wake.
Solution: Reverted back to .98 with flashtool. Now its awesome again.

I had 0% drain overnight last night with this update

If you mean Diagnostics under 'About phone'. I went through all the tests, nothing crashes on mine? Or do do mean elsewhere?

Yes, I meant that, and then the second option "phone characteristic" or something like that, then you see how many times the phone crashed and what processes are involved

I too am having terriblr battery drain after updating to 23.0.1.A.5.77, I've tried everything; Factory Reset, Flashing back to previous builds. All to no avail.
I've installed Gsam Battery monitor and it tells me that 'Android System' is constantly draining and is at the top of the list.......
I really dont know what to do.

haven't noticed anything different really after the update. the battery life seems the same

I noticed battery drains on my Z3 after the .77 update so I did a clean reflash and after letting it settle in for a few days the battery is back to performing awesomely

I heard such battery issues and still went ahead to see does it really hungers your phone so did the update and I hardly notice any unusual battery drain.
My screen shows 45-61% battery usage and rest all fine. Dont know how to reduce that but its ok.
I get 2 1/2 days battery easily without any stamina mode activated so I guess it pretty awesome. :fingers-crossed::good:

Hi, I did not find a battery drain on my z3c but did find out something on my prev. phone, the z2, my phone went battery hungry after flashing update so I gave it 2 days to settle. The drain kept, driving me nuts. I than did a full wipe didnt help. After formating the sdcard away was the battery drain! Probably some corrupted file or sector on the SD kept the phone draining the batt.
Also seen on other phones that some malfunctioning simcard could disrupt the stability and power usage. Some operators use cheap cards that can just die on there own.

Nexus 6p Battery Issue

Hey Guys,
I have a nexus 6p the 64 gb version ,and its one of the greatest phones I have ever owned. Everything about it is great, unfortunately the past couple of weeks my phone battery started to drain extremely fast. My phone now doesn’t last a full day and it constantly overheats. I’m a very heavy user, I almost do anything electronically on my phone, but before the battery drain my phone didn’t overheat nor its battery drained that fast.
There is no apparent reason why this is happening, I did not change my frequency or intensity using my phone. But I think there is possible reasons:
-Google latest update
- Charging my phone BRIEFLY with a non-certified type C cable (I didn’t know there was an issue with those cable before)
- A certain application that runs in the background (phone is always warm and when on usually overheats even if just browsing)
One of the great things I admired about my Nexus was its long lasting battery life and rapid charging. I’m really disappointed, I really liked this phone and wanted to last. Please if anybody faced the same issue or have any suggestions, solutions etc, please share. I have attached a report showing my battery use.
Thanks Aalot
**my phone is not rooted or anything it’s just plain stock android

The first thing I would have pointed out, is a custom kernel, tweaked inappropriately. But you ruled that out.
Now since your device is not rooted, there are not much ways to track the drain. I certainly believe that, there is a specific app that is causing the drain.

First of all, thanks for your response.
A small percentage of the battery is consumed by apps the rest is for the screen

Do you know any application that can measure each app battery consumption. Because it will be very difficult determining which app is sucking all the juice

GSAM would, but I heard it is a battery drainer itself on the 6P.

The drain was there before Gsam actually I used it to investigate the cause of battery loss and forget about how it can measure app consumption

I just got mine last Thursday and I'm also a little disappointed with the battery life. When I set up the phone, there were 3 or 4 google updates and the phone only lasted for less than 8 hours. I'm thinking it's due to the whole set up process.
I did a hard reset due to missing wifi passwords and I'm currently monitoring the battery drain.
Coming from OnePlus One, the battery life on this is really disappointing. But then again, I always have my anker battery charger with me. I'm hoping once the apps settle, battery life should improve.

I uninstalled FB, Messenger, and a couple of other apps that were restored from initial set up, powered off and wiped cache. So far, battery is holding up. If drain continues, I will factory reset and install apps one by one

I am having some success with wifi off during sleep and turning off bluetooth.
I find my wake locks come and go - some days doze works like a charm while other's it disappoints.

Facebook messenger used to drain my last phone battery (HTC One M8) at an alarming rate. I've just used the Web browser since.

Hey guys, I removed alot of applications, and btw I never installed Facebook messenger on my phone. But the battery is still draining.
The phone is constantly warm, and sometimes hot, even if its on standby.
Any suggestions?
Its very strange that the majority is not facing this issue (it's a good thing),

This is happen to me too. No new app. It is appear that if I reboot the phone after disconnect from from the charger then it is doze normally otherwise android system will keep the phone awake. Bluetooth does not seem to matter on or off. This is happen after april ota.

Go to Settings >Battery and see what is causing it. It may be an app that you updated. Try wiping cache or uninstall/install the updated app. If still draining, you may have to factory reset from boot and install apps one at a time instead of restoring backup.

Yeah, I think the last update was the root cause, there is no other reason. I will do a factory reset soon and will update you

Same here. Tired of this sutuation already, sometimes it works properly 1-2 % even 0 on morning, but sometimes it loses 10-15 %, I didn't install any new applications in monthes, it just started.
