Please help, wakelock

I'm so frustrated with my phone battery. I go to sleep at night with my battery at 99% and I wake up 4-5 hours later and find my battery drained to 30%. I use better battery state (screen shot), but I can't figure out what's keeping my phone awake...
Can someone please explain how to find the source of this problem? I appreciate it soooo much.

Btw, if it matters... This problem been stuck with me with all of the ics roms, all roms. I have like 30 apps installed... do I deleted 1 app a night and wait to see what happens? Any other way... Need your help sooooooooo bad.

You will probably get a better answer in the better battery stats app forum. Read the directions on the op, post a system dump and Chamonix is great about helping out.

Do you turn off Wifi when you go to sleep? I'm only asking because I see it's on in the SS. If you don't turn Wifi off then that's your culprit.

if it were me, I'd install gsam battery monitor (look for it in the market, free) and go to 'app sucker' and look at the "View Time Held Awake" and the "View Num Times Waking Device" to find out which app is causing your heartache.

I also had the same wakelock problem, using BBS it was "*backup*" which is a google sync I believe, just froze it with TB, and problem solved. Using BBS, just change the settings to show "partial wakelocks" and have it set to show "since unplugged"

Why don't you just charge your phone overnight? I wake up every morning and my phone is at 100% when I wake up

Thanks xda'ers
I will give all the replies a shot and report back.
Brook... I do, I'm just trying to find out what is killing my battery day & night. I remember Calks GB lasting me at least 20+ hours with light usage, now with no usage I pull my phone to find its almost dead... Sux ya know

Note 4 Always awake

Hi,
Attached are screen shots of my battery life. As you can see it is always awake.
One is on ART and the other dalvik. If I restart it will deep sleep for half a day to a day and then go on always awake.
Any thoughts on what it might be?

Looks like you have a really bad network connection which is keeping your phone awake

I disagree. My signal is worse here at the office. And my phone sleeps.
OP, I have the same problem from time to time. But I've never narrowed down what's fixed it. It's just magically gone one day. Hopefully someone has an answer.

Have you tried running stock before you install your apps? Maybe one of your apps is rogue with the system

What do you have installed? I'd look at the apps you installed as well as your location settings.

I usually keep location off and that doesn't seem to be pinging. The app I notice seems to have some correlation is Audible but I haven't played with it enough to say for sure. I don't think it is signal strength as if i just restart my phone it seems to work as intended.
Luckily it seems to keep the CPU running at the lowest setting so it hasnt destroyed my battery life but I go for 4hrs SOT of battery life with 50% remaining for a day to hitting 50% by 2-2:30 hrs SOT.

Stock OS

Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).

You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.

Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.

Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

On the off chance that you or anyone else can help me understand what's going on I ran a ~10% drain test and made a picture including information from WakeLock Detector and GSam. This drain seems very bad considering the screen was only on for a total of 16 minutes and I lost 8% power.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

Do you have any recommended settings for that app? I disabled something that I think is allowing me to enter deep sleep more, but I have to finish testing. Thanks for the help ratbags!

Oh I see what's the wrong.
Battery usage give me a wrong information.
My fire phone lasting about 5hrs turning on screen.
Very very good !!
Thank you.:good::good:

Five hours is good??

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.

Battery Drain

My 10 now is starting to drain battery real quick without doing anything. No unusual apps draining much. I used battery tester in the secret testing menu thing and it said my battery is fine but I don't think it is. Any app or something to test battery or any way to test if it's rom related?

Installing GSam battery monitor from the Play store would be a good start. You can monitor wakelocks and app usage, which can help diagnose your issue. How long does your battery usually last after a full charge, and what kind of screen on time are you getting? Also, does the phone ever get warm while you're using it?

Not sure how to read gsam battery logs but here is a screenshot and phone does not get hot. With not much use, I only get from 10am to around 2 to 3pm which is not normal for me.

From the main screen, you should have 4 icons at either the top or bottom of the screen. The second icon from the left brings up the app usage screen, and there is a drop-down menu at the top so you can view different things, like kernel wakelocks, etc.

OK I see but what am I exactly looking for? Wake locks? Not sure what's good and what's bad in terms of %s and what not

Like I said, charge your battery up to full. After a few hours off the charger, post screenshots of the main screen, app usage screen and kernel wakelock screen.
Also, press the triangle icon on the main screen and make sure "Since Last Full Charge" is selected.

I don't see anything out of the ordinary, but that doesn't mean there isn't an issue. There are a couple of things you can try. First, you can try and recalibrate your battery by turning the phone off and holding the power and both volume buttons down for approximately 2 minutes. The phone will cycle on and off a few times, which is normal. You can see how the phone works afterwards, and if that doesn't remedy it, I would RUU and start from scratch.

Cell Standby Drain - is there a fix?

Currently my phone is at 30% from 100% - 21 % of that is cell standby (mobile radio active for 16m it says), and only 18% of that is screen on (4.5 hours~). I tried turning off "keep mobile data active even on wifi" but that did nothing. Is there a known fix? I thought maybe turning off VoLTE would do it, but it just switches itself back on.

Strange. Last night for me the battery drop over 7 hours was zero. So I can't complain on standby battery drain.

Give some context to this maybe? Like how long was your phone on for? For instance, my battery is at 55% at 12hrs on battery with cell standby at the highest with 7% and my Screen using 2% with 2hrs SoT. Cause if your standby drain is over a full day, maybe you just have bad signal where you are?

Volte drains very little amount of battery. Do you have other things enabled like WiFi, NFC, Bluetooth, GPS, auto sync etc. which could keep the phone awake ? Download Devcheck from play store and check if your device is going to deep sleep.

Gps is on as well as wifi.
However as i have posted the battery usage per service. Only cell standby seems to be hogging most of the battery...
I am only left with resetting my device as a last alternative.
Checked via devcheck, it's a no go for deep sleep.

Android battery usage data can be unreliable. To check if cell standby is what actually draining battery try this-
Before you go to Bed, open Devcheck app on your phone and take a screenshot of deep sleep time after that leave your phone alone. Next morning open the app again and check the Deep sleep time. If all those hours are added to deep sleep, then cell standby is the actual cause of the battery drain. If the deep sleep time is similar to the night or only slightly different, then something else is keeping the phone awake and draining the battery.

Hey... Got it working... Thanks for ur advice but I ended up doing a hard reset of the device. And now the cell standby drain Is just 2-3 % overall.
Thanks though for ur help. I appreciate it. ?
