[Q] Weird periodic battery drain issue - Nexus 5 Q&A, Help & Troubleshooting

Hi,
Since about December (a while after updating to Lollipop), I have a weird battery drain issue, once in a while.
The battery drains very quickly – about 15% per hour. Phone gets warm (obviously) and sluggish. Killing apps doesn't help. Battery stats don't show a culprit.
A weirder symptom: if the notification bar shows I have new Gmail messages and I open Gmail (from an icon in the quick launch area, not through the notification), the Gmail icon doesn't disappear from the notification bar (as it normally does).
Also, my clock widget (HD Widgets) stops updating (I think this doesn't always happen).
A reboot helps briefly, but usually within a few hours, it starts draining again.
Then, after anywhere between ½ and 2 days, the problem disappears, only to come back 2-3 weeks later.
Any thoughts? I'm on stock, not rooted, not even unlocked. (So I can't use BetterBatteryStats or tools like that without a factory reset, and I don't have the time to deal with that right now.)
Here are my battery stats from last night:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I took my phone off the charger at about 2:40, it was draining at the time, it looks like. Rebooted at about 3:00, briefly did some reading, then went to sleep.
At about 6:00, when my phone was quietly lying on my nightstand, the drain starts again. At 7:30 I woke up, rebooted, and made those screenshots.
The first screenshot shows no obvious “offenders”. The second screenshot tells us that something is keeping the phone awake, but it's not just being awake that's the problem, because the battery drains faster, with screen off, than in a normal situation during light use (reading) with the screen on.
Any thought? Thanks in advance!

Odd tip, clear cache. But yeah read the first four posts plus last few pages of the battery sticky thread.

Awake and Screen on should pretty closely match each other. An app is keeping your phone awake.

See the battery thread as said before, and wakelock detectors pc version doesn't require root. Look into it, cause something held your phone awake solid and your battery plummeted. ?
You have a Nexus though, Root it! ?

[HELP] Battery Use App has gone mad!?!

Hi folks!
I tried to search the topic before starting a new thread but I couldn't find any.
So, here's my problem. I noticed that since I flashed the stock JQ1 Gingerbread from chainfire's thread apart from everything else being fantastic, the battery use statistics in Settings -> Status -> Battery Use I can see are stranger and stranger.
First I have noticed that my the battery usage of Display had frozen to 2%. It is completely impossible, comparing it to the Froyo before, where it often went beyond 50 or even 60% of total battery usage.
Then, I saw that the Android System was taking about 90% of the stats. At first I thought it may be the infamous Gingerbread battery drain. It is not that, however, because I do not feel the battery draining any faster than before.
Then came the realization that no matter what application I am running, it does not get reflected in the Battery Use - only Android System percentage grows bigger. The funny part is that from time to time the total of all percentage goes beyond 100%
And, finally, today I unchecked the background update of the PULSE application, because I do not really use it and checking the Battery Use again what did I see. See attachment:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Not only the display category had gone away totally, but half of the battery usage is now transferred to PULSE, which I don't use.
Please, do you have any ideas how to repair that?
I am on a European Galaxy Tab, JQ1 2.3.3 Android + CF-Root v3.3 for JQ1
Not anyone experiencing the same problem? Just a little update from me. I read half the cloud already, strange but it is the first time that I cannot really find my topic in Google.
I tried what not - no result. I wiped battery stats, which only helped to the extent that the PULSE has gone from battery use stats, and display is back but the readings are stuck at 2% no matter how much I am actually using the display.
I read somewhere that it could be the kernel, where some thing may have not been allowed or switched on??? But if that was the case I would not be the only one with the same problem, but all the people that have flashed the ROM + CF Root 3.3 from chainfire's thread????
Still no ideas?
Hey guy,
Once ago I had the same problem. I don't think that pulse realy eats your battery. But we all know that the battery statistics is incorrect. So don't worry. Do use "AntTek App Manager ☆ root" (its free) to remove the puls app and wipe the cach. Or just install the overcome rom. It's much better then the Sock Rom. Trust me Because after removing of puls, there are other false statuses. I don't remember but i think it will show you that the battery is eaten by the core apps for more then 70%.
Sorry guy... I know about my terrible english
Hey odysseus84,
don't worry about your English. I am glad that you tried to be helpful. It is not that bad. After all I understood what you mean. You are right, even without Pulse in battery stats, I am still missing statistics for practically everything.
It is interesting that the Battery Use fails to record third party apps. As you can see below, the usage for all main system processes like Idle, Standby, Bluetooth, Wi-fi, Voice Calls are there. The statistics for display usage is stuck at 2% as already mentioned, which is the most annoying part.
Another interesting thing is that everything seems to be put into Android System usage, because normally it wouldn't get more than 10% of the overall battery usage share.
May I ask for other people running Gingerbread 2.3.3 to post their battery stats here?
Look. It's just a Bug. There is "Android System"written but it means the % of the Display. There is "Display" written but it means something else. As you can see on the attached pic we have almost the same "Display" usage.
And the other thing is that the statistics nothing shows with less then 2% usage.
Finally you can just accept it or flash something else.

Battery life is is bad now. 4+ hour wake time.

So I had great battery life not too long ago but now I can barely make it a whole day. My awake times are very high and I can't pinpoint the cause. I attached some wakelock detector info. Right now I have about an hour and a half of screen on and 16% battery left.

I am having same issue with phone getting really warm. No new app installs other than things like wakelock detector. I can't figure out what is causing it and better battery stats isn't showing me anything.
Add me to the list. Never needed my third battery until yesterday. No out of the ordinary modifications.

Try freezing maps and other not needed Gapps, it solved my long wake times. I also use Tasker to hibernate all my apps then put the phone in airplane mode when the screen turns off then waken them up and turn wifi back on when the screen comes on, battery life through the roof

So what's a normal awake time?
I've had battery problems in the past with other phones but usually wake lock detector can find the offending app. Nothing is jumping out at me this time. Google seems to be using a lot but I would like to keep using those apps unaffected.

Same here I took my phone off the charger at 10pm by 1am I was down to 37% with 17 min of sot, something isn't right, I'll try to grab ss tonight. And yes the phone gets really hot
I just had my G3 replaced after my new one suddenly died on me.
I notice a couple of subtle software changes by AT&T.
Yesterday my battery was on 60%. Before I left the office.
When I got home (45 minutes) I took the phone out of the pouch and it was really hot and the battery wad won to 19%.
First time this has happened to me. Will have to monitor.
I got fed up with it all. I did a factory reset. I'm going slowly re add apps back. I certainly noticed a performance bump after the factory reset. Night and day. I didn't even realize how much it slowed until i reset it.

wake lock detector isn't really a good app for telling you exactly what the issue is. betterbatterystats is your best bet to find out exactly what the issue is - it will tell you precisely what the issue is holding your phone awake.
Sometimes, shutting down and pulling the battery out for a second is all it takes to fix the problem. rebooting doesn't always solve whatever it is...
My phone "freezes" now and again, it always has something to do with me texting, but screen off and on will fix it..and it does get warm when frozen per say...but it will normally fix itself with me interacting with it. But if your guys are not holding it when it happens I can see it draining out your battery stuck at higher clock for no reason...now wonder if I should pull logs....
When I say interact I mean I have to push the power button. Knock on won't work. Similar to the dreaded sleep of death but seems to pull out of it.

Like another user mentioned pulling battery or at least resetting the phone periodically helps with battery and helps keep things running smooth. Using Better Battery Stats and looking at Alarms and Partial Wakelocks is a good way to determine if there is a rogue app killing your battery. A couple good Xposed Modules, if you're not using them or aware of them, are Greenify to help hibernate apps that like to constantly wake the phone and NLB Unbounce module is a good one for if you want to keep your location on and keep Google Now functionality. You can set how often you want the wakelocks and alarms to trigger and with the donate you can do the same with any wakelock/alarm. Just be cautious if using the pro version as some alarms or wakelocks if disabled or tinkered with incorrectly could make the phone unstable. Just a few tips/ideas. I have the VS985 and have had pretty good battery life since getting everything set up and debloated. Usually about 17-18 hours on battery (I don't sleep much) and 4-5 hours screen on time. I like the screen on the brighter side as well, which usually I adjust with the status bar so I don't have an exact percentage for the brightness. For some other tips and apps or even maybe something you haven't thought about check out this thread: G3 Battery Tweaks :good:
Factory reset.

I noticed my phone was getting warm in the pocket too, with bad battery life. I finally figured out the phone was waking as if it thought it was getting the 'double tap' to wake. I believe you can disable the double tap in the secret menu (3845#*850#)

Z3 D6603 - Battery life is not good

Hello,
So recently i've noticed the Battery performance on my Sony Xperia Z3 has become poor, I mainly use my device for socialising etc, I don't game alot. I'm currently Running Android 4.4 Kitkat (UK)
(I'm usually at home and connected to Wi-Fi)

Check if the device is constantly awake at the detailed battery information if you click on the graph.
If that's the case, search xda for "wakelock" and how to get rid of it.
An easier attempt is, to think if it's a certain app you installed recently or a change you made to your system.

Thank you for your response,
I'll Go ahead and download a Wakelock Detector By someone who works here at XDA, and i'll see if it finds anything; But as of now my battery died again; So i left it dead for 15 minutes, and now i'm charging it back to 100% with no interruptions

You could also install the ota update for lollipop and see if that automatically solves your issue. (new versions are being created to be better)
Another option is to flash the lollipop stock rom and try if that solves it. (but that's a bit more advance)
I suddenly got a similar issue - not as bad as yours but a drop in battery life. I turned off scanning even when wifi is off and turned on location based wifi and my battery life went back to normal. I'd just had a Google Play Services update and have had this issue with various play services updates in the past on other devices which is why that was one of the first solutions I tried.
Might be worth a shot if you haven't already tried it :good:
There's always Greenify.
Repair it or flash another ftf file.
Same thing here. Since I've had this when I purchased it new I've not had any good battery life. My old z2 had way better battery life and stamina mode works.
Sent from my D6603 using Tapatalk 2
Was there any update to this matter, OP?
What brightness options are you using? (% and adaptive or not?)
Also, did you actually update it to Lollipop? Was there any problem with wakelock?
Best regards.
Network & Wake Lock
The last screenshot you posted clearly shows that the battery drain is because of your Mobile Network and a Wake Lock.
Network Signal:
As signal strength decreases, the device requires additional power resulting in battery drain.
The cost of 1 hour’s worth of calls is 150mA, assuming a strong signal
So, on a 2000mA battery, it takes 8% of total capacity (8% =150 / 2000)
This means the same 1 hour of calls could cost as much as 23% of battery life (23% = 450 / 2000)
Wake Lock:
WakeLocks are a Power Manager system Service feature, available to your applications to control the power state of the host device.
Wake Locks can be used to keep the CPU running, prevent the screen from dimming, prevent the screen from turning off, and prevent the keyboard backlight from turning off.

Help finding/fixing idle battery drain

Hi my wife bought a Note 5 two days ago (9/30). She did all setup, app restoring, etc that evening and fully charged the phone overnight. However her phone is experiencing idle drain that I need some help fixing.
Some other info: battery saver modes are off, wifi is always on (but only connected at home), bluetooth is always off.
10/1: Arrived at work with 100% battery
A little over 4 hours later, with light use, the phone was at 51% with less that 45 mins SOT

With facebook as the biggest offender I suggested she turn off the setting of pre-loading pics and videos.
When she got home she charged phone to 100%. I also changed mobile network to CDMA/LTE. Here's how the battery looked with light use before going to bed:
10/2 - Left the phone unplugged over night to see what would happen, it lost 12% sitting on the nightstand for 8 hours.
Will report back later this afternoon to see how the day is progressing.
First step for me in reducing battery drain was to disable the Facebook app. It is a battery hog and was always at the top of my list. Instead, use a browser and create a shortcut to facebook.com or install Metal from the Play Store which is a web wrapper for Facebook and so much lighter. Sometimes I still get strange battery drain from Android system (up to 35% sometimes!). But this usually gets resolved just by opening up recent apps and closing all.
Hmm, I don't have problems with Facebook app on my droid turbo

Some people want notifications.
Regardless, Facebook doesn't seem to be showing up at the top afte the setting change. I'm interested to see what she has this afternoon. Will have some updates screen shots later on. I also asked her to charge ~3pm then drive home with nav on to see what the battery looks like under heavy usage.
I need to dig into Android System to see what's going on there, any ideas? Will GSAM pro give more insight here?
Not looking good, 22% used in 2.5 hours with 20min SOT

I lied, facebook setting is "play videos automatically", I have to assume turning this off will save data/battery. Also Instagram has "use less data" setting. I thought I read that this stops pre-loading of videos/images, but I might have imagined that?
Anyway, for facebook setting hit the menu button next to the notifications icon then scroll to "App Settings" near the bottom of the screen.
After most of a work day and light use she's down to 58%. Looks like facebook is back up there, odd because it's not a problem on my phone.
Does anyone know how to troubleshoot why Android System is using so much battery?
I have a note 4 and I'm having similar issue ls

You guys have to also take in consideration the Lollipop total connection time bug. Apps open up a connection and it won't close it when it's done... For example my first charge cycle I signed into instagram and it used 40% of my battery without me ever open again. The total connection time of most apps ends up being hours when it shouldn't be. That won't be fixed untill Marshmallow comes to the Note 5. Google is aware and has fixed it. It's on multiple Lollipop devices.

Yea I've used that for a while. When I force stop an app I tend to not see it encounter that bug

If the device is rooted then you can try Greenify to hibernate the apps which are consuming the battery life.Try other simple solutions like disabling the Wifi and other tools when not using them.Sometimes Play services may cause the issue so try to fix them.There are some guides which may help you http://fixdroidbattery.net/fix-fast-battery-drain-problem-on-samsung-galaxy-note-5/
http://recomhub.com/blog/how-to-fix-samsung-galaxy-note-5-fast-battery-drain-problem/
Hope these guides will help you
The problem is ...because of the device used to be root although we flash original stock firmware it is still drain when device idle ...you can take a look in Android OS and see stay awake period ...one way is flash custom room that said deep sleep fix . Hope this comment could deal your problem

Question Huge battery drain when sleep tracking after updating to R860XXU1CUJ2

Hey there. I am noticing a big battery drain on my GW 4 40MM Bluetooth when I am going to sleep, for example last night I've gone to sleep with 83% of battery left and in the middle of the night the watch died, the same thing the night before. Normally I would get about 20-25% loss with previous firmware
This problem started after I updated to R860XXU1CUJ2. The strange thing is that I am not noticing bad battery life when I wear the watch in the day (maybe a little more draining compared to previous firmware), also note that I am just using regular sleep tracking not O2 or snore detection even though I have used this options with the previous firmware and still I had battery when I woke up.
Does anyone else has big battery drains when sleep tracking and also is there an official site where I can make a ticket?
Thanks!

I turn off Bluetooth at night and I want to try if keeping it on does anything, because as you can see from my screenshot it uses Wifi and maybe this affects the battery life at night. Do you keep Bluetooth on or off?

I would say you've got your answer. If you have enabled the option to continue receiving notifications via wifi or lte then turning off Bluetooth will inevitably use wifi all the time and result in high battery drain, most probably...
CUJ2 version as well, 28% battery drain during the night. I just left the watch on my table. No sleep tracking. No wifi. No app listed under battery usage. Nice!
Is there a way to get more details on battery consumption?

Same problem here. In this update, I think the Watch WiFi is set on when I turn the phone WiFi or data off. It's not happening before this update.

I agree with DaReDeViL. You have your answer. Why do you turn off BT and leave on wifi? Wifi uses significantly more power. I'm on newer DUJA but I saw no issues with CUJA which I ran for several weeks. I have sleep tracking on without O2 or snore detection. I don't have BT or wifi on when I sleep though. I have no desire to get notifications when I sleep, I want to sleep. I actually use bedtime mode when I sleep. I loose between 4 - 6 % of battery when I sleep (I average about 7 hours). This has remained fairly consistent with every update.
