[Q] Who's to blame for battery drain?

My phone went from 90% batt to 0% in 5h of screen off time. Usage shows Android OS 60% and SopCast 30%.
When i locked the phone i left it on the home screen.
So who's to blame? The rom, kernel or the app?

could you please provide a bit more detail like what kernel or rom you have and also if you could upload screenshot of battery usage

Rule out your application first. I'm assuming SopCast is a podcast application? If you were streaming, that will explain it. And yes. We need more details.

Thanks, i used to have it installed, but i could never interpret any results from it since the lingo is beyond me (i.e. partial wakelocks, kernel panics...).

Well the same here lol. However if you focus a bit you'll find out some nice things. Kernel wake lock will give you the apps that keep your phone awake. For me its mostly the exchange which is email. You can take a screen shot and share if you'd like.

Anyway this is no longer related to that obscene 90% overnight bcuz i uninstalled sopcast. Now i just had 16% drain overnight (with Wi-Fi off) which is still a lot imo.

Having 18% drain overnight on JB with wi-fi off. Any ideas?

Why are turning wifi off in the first place? That is stupid if you're trying to extend battery life.
What is your cell signal like. A crappy cell signal drains battery. A crappy 3g signal that is constantly on because you turned off wifi drains even more.

i was under the impression (from gingerbread times) that wi-fi uses up more battery than 3g; this was among the tips you would find back then on android sites to extend battery life.
Anyway, i have yet to find out who is calling the AlarmManager that is keeping the device awake. Any idea how i would go about doing that?

Hi, like the other guys said that are trying to help u....
We need more information to try and help u figure it out.
What ROM?
What kernel?
Any other modes or tweaks?
Vs Nexus S 4G using Tapatalk 2

I didn't mention that info so far because the initial problem of this post is fixed (SopCast (podcast app) keeping phone in stream mode) by uninstalling the said app.
Now, i believe that the overnight drain on my current JB ROM is too high.
So, here it is: Rom is Grean Bean ( http://forum.xda-developers.com/showthread.php?t=1821478 ), kernel is Matr1x 22.5 (but the drain didnt change when i changed kernel (beladus, _thalamus, air) and the significant mods that the rom has are V6 supercharged and brainmaster's twks.

That was not the case in GB times or any times. Either you read wrong or the sites are stupid. Considering that for the most part the android sites / bloggers are still idiots today, who knows.
Anyways. WiFi uses the least battery. Less the 3g/2g. Should be used whenever possible to save battery. Phone in active use or idle you should be connected to WiFi over cellular data. Turning all radios off but enabling WiFi is the most battery efficient thing you can do and still have data but you won't have the actual phone. I do that at my buddies house where I get no service at all. Not going to use the phone for a couple hrs use airplane mode. That uses very little power if the phone is sleep. Turning the phone off and on uses more.
Also the better your signal is the less power the phone will use. You still gave no signal strength info. Frankly you're wasting your time with better battery stats and wakelocks etc when you don't fully grasp this radio stuff. Use that tool when you need to find something that keeps your phone awake when idle/not in deep sleep.

That's the situation i'm in. It seems i've solved it by figuring out which apps were calling the AlarmManager and the Media server, there were 2 actually: Latitude and Google Music Sync, that were waking too often. Now i've simply disabled them.
I didn't give any signal strength info, bcuz i didn't move and didn't change the radio. It's a jelly bean thing for sure (i have google now disabled). Many users have been complaining (in various rom threads) about this new found drain after the upgrade.

Yeah, I normally play with a new ROM bare boned to see if has a natural drain.
Then I add the apps that I have been using that I know do not drain battery life.
And the other person is dead in with the signal advice. I had a HTC hero before and it had many tweaks on fixing the signal so battery would last. Which is why I love the pull down notification bar and some ROMs have idle timers.
Good luck

[4.4.2] awful battery life post update

Hello everyone,
This is driving me nuts. I have went from good battery life under 4.4 to completly awful under 4.4.2. I am running stock 4.4.2.
Here are some screenshots. Can anyone figure out what the issue might be ? Why would my screen stay awake even though it's clearly turned off ?

Sorry, I've experienced the opposite since my upgrade. Great battery life for me. Not sure you are seeing a 4.4.2 issue.

Did you go to stock 4.4.2 from a custom rom, without wiping data?
I went from custom 4.4 to 4.4.1, dirty-flashed. When I went to 4.4.2 it *****ed at me about wiping data and then **** started to break.
After factory reset, mine's been utterly golden. 76%, 5 hours on battery and most of my use is the screen and occasional game played.
Completely stock, not even root.
Yesterday, I was at 49% after 12 hours, on wifi all day, streaming a couple of hours of audiobook via bluetooth during commute.
That's the kind of performance you should be seeing on proper stock 4.4.2. Only thing I could suggest would be to factory wipe, reinstall the base 4.4 image and update from the OTA.

I flashed stock using the factory image. I then sideloaded the 4.4.2 update. Configured the usual settings, nothing fancy or out of the ordinary.
Couldn't be more stock than this (minus the root for BBS).

I'm quite surprised by this. Got my nexus 5 yesterday, so obviously I played a lot with it today. Did the 4.4.2 update immediately after unboxing. got juice defender running on a balanced scheme and had lot of WiFi today. Navigated for a bit and got this result.

It's been garbage. I'm having notification issues also. Will most likely revert to 4.4.

bam_dmux wakelock and powermanagementservices_wakelock are the big culprits. Your wakelocks drained your battery 33% in 2 hours. Could be a radio issue.Should be the .23 baseband installed on 4.2.2.

Will people stop quoting the 3 enormous images from the original post? He knows you are responding to him as its his thread.
I see at least half of your problem is the wlan_rx_wake bug that I and many others have been experiencing. There is no fix for this so far that I have found.

just cause its constantly using your mobile data doesnt mean its pulling down big files or anything like that. something is just waking up your phone mobile data using it, and not letting your phone idle.
could be exchange. disable it for a day and find out.

It is not normal for wifi to keep a device awake when the screen is off and nothing is happening on the phone. My router keeps my phone awake for hours a day. No other phone I have ever had has had this problem. Its a Kit Kat problem.

Check the OP again he clearly does.

Thanks for the help thus far. I will flash stock image again. Root for BBS and see what happens under 4.4. If all goes well I will sideload 4.4.2 again and post the results.
Battery life was great under 4.4 for me... but I really want the improvements to the camera in 4.4.2

Flashed back to stock. Didn't update to 4.4.2. I just lost 17% in 24 minutes. I am not even rooted. I
Did not even configure anything. Just flashed, logged into my Google account and watched it drain.
Screen has been on all the time under auto brightness but it should in no way consume that much power.
Thoughts ? Thanks
(Edit) 22 minutes out of 27 using the screen. Went from 50% to 31%.
(Edit) Tried airplane mode with screen turned off. Lost 2-3% in 6-7 minutes.

Nexus 5 battery problems

Hi. I have a two-months-old Nexus 5 (stock ROM & kernel; rooted). Two days ago my battery suddenly started having some problems. First of all, it doesn't last more than 1-2 hours with normal phone usage. Then it often becomes hot, even when not charging. Last but not least, if I keep using my phone while charging, it charges incredibly slowly, or it doesn't charge at all (the charge remains stable). I'm using the stock charger. Any suggestion?

The Nexus 5 has been proven to last longer then an SGS4 which has a bigger battery, and the HTC one with the same size battery (under proper testing conditions) all while using a faster SoC. Do you troll the forums for those phones as well?
Maybe a Moto G or LG G2 would suit some people better for their increased battery life, but that doesn't mean you need to troll every thread on here with false accusations.
If you'd like any more proof on how the N5 battery lasts longer and is more efficient than competing phones of higher prices, just let me know.

I did what you said; I have attached some screenshots. I'm not an expert about this, but it seems like you were right. What shall I do?

The most important stat to look at is partial wakelocks - it lets you see which app or apps are waking.

Go into device settings > Location. Set Mode to Device only. Ensure that the Google location reporting in that same area is off.
Take another BBS log and post it.

I experience the same issues. Not charging when connected or even lose charge when connected. I am still figuring out what causes it. First of all try using the original cable and charger. Second, disconnect the charger when the screen is on, I read somewhere that can help as well.
Today I had the same issue again, but just before I started charging, the battery would lose 1% per 2 minutes and my phone became very warm.
If I find out more, I will let you know.

EntriesRefresh_wakelock (com.google.android.googlequicksearchbox.Google Search): 4 h 47 m 17 s (17237 s) Count:0 98.6%
That is the problem. That particular wakelock belongs to Google Now. I hope you don't use it, because the solution is to turn it off (from within the program). You could try force stopping and/or wiping it's data. But the fact of the matter is that it's a bug in the app.
Google Now has been this way since it was released. The only conclusion I can draw is that Google doesn't care. It's never behaved properly. And that location reporting (that you've now disabled) is completely out of control, been that way for a year now. I actually greenify the Google apps now. I'm tired of putting up with the lazy programming. Keep, Now, Chrome, Drive, Maps, I greenify all of those. I still allow them to sync, but Greenify will kill them again after they are finished.

I can confirm that I have no battery problems anymore (today after 6 hours of average usage it was still at 80%!!). Thank you all for your help!

Good to hear. If anyone else see's Android OS or Search taking up 50% or more of your battery that can be mitigated.

Take out your Battery, put it on a flat surface say a table. Try to Spin it....if it spins over 2 rounds then you need to buy a new battery.

OPO battery drops dramatically after the last OTA

After installing CM13.1-ZNH2KAS254 the battery lasts only four to five hours by merely using the phone.

- How many full cycles have you had since updating?
- Are you using the original OPO charger and USB?, aftermarket products don't offer the same charge rates so may affect battery use.
- You have a device that is 2 years old, the battery regardless of it's total charging cycles is already past its 12 month expected lifespan.
- Try clearing the cache via recovery, this is something always recommended after an update, regardless of how small as it irons out any duplicates or issues.

I bought the phone this year, I am using the original charger and cable, but I have been charging it whenever I had the chance because of my work. For example from 35% to 80%, never letting the battery drain out completely. I contacted OnePlus and they advised me to let it shut down and full charge the phone three times. I will post the resaults.

I also use tethering a lot, at home on my desktop pc. I see that while tethering is on, the phone is charging really slow, like 1-2% every 10 minutes. Could this be linked to the battery lifespan?

This is a known issue of slow charging with the latest official update. If you are rooted the device, you can switch to Custom ROM like sultanxda's which does not suffer from slow charging.
Battery life actually depends on how you use the device. If you just use the device to read, it'll last longer. If you use the device only on WiFi, it'll last longer. If you have good network coverage, it will last little longer and most important is the age of the device.
Battery drain can be because of some of the apps using the device resources(like Google Play Services etc) continuously and not allowing the device to go into deep sleep mode.
Tethering drains a lot of battery as your device acts as a router and gets the power from the battery

This is a common issue on MM roms and the OPO.
Lots of people are reporting wacko battery behavior after upgrading to MM.
In my experiments, the CM 13.1 by Sultanxda was the least offending, and possibly COS, but I don't exactly remember about COS.
Switching back to LP will correct any battery issues.

What about screen overlay which is very frustrating.

It's been almost 1.5 years since I'm using my OPO.
With the latest COS update, battery backup hasn't changed anything toward bad if not better.
6-6.5 hours SOT always based on my usage. While I get under 5.5 hours SOT with similar tweaks using SultanXDA CM e.g.
COS 13.1 is running really good for me, battery is great, and honestly, since COS 13 came out, I've literally stopped using custom ROMs while on COS 12/12.1 I was barely using the official ROM. Mostly was on Resurrection Remix.
So battery backup wise, COS is "GREAT" if you know what to tweak, and yes the phone charges from 1%-100% in 1.5 hours using the stock charger.
Do a battery calibration, complete calibration, here's what I do after every flash, drain to sub 1% when phone turns off, go to recovery and keep it there until it "completely drains itself to death", then start charging from complete zero all the way up to 100%. That works for me, can't take any guaranty for your device though.

[SOLVED]
I did what they suggested and the battery lasted a full day, 08:00 to 02:00.

S10E stand-by battery drain. Let's get on top of this.

So, I have a Exynos variant of the S10E and I'm having mixed result with battery life:
If I use my phone a lot (and I mean a lot) for example when I'm traveling i get about 6 hours of SoT which is great with a 3.100mah battery and heavy usage.
However on a regular day the phone just seems to discharge itself when in standby mode and I don't even reach 3 hours of SoT.
My setup is simple: all apps are disabled when on standby except for WhatsApp, Telegram and some e-commerce stuff and in the Battery stats "Android OS" in on top of everything (except for screen).
Are you having the same issue? Did you manage to find the cause? Let's discuss it.

This solution was posted on the S10 forum and certainly helped me.
There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.
You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.
Cheers!

Hi! Thanks for your feedback.
I have my S10E scheduled to reboot every night but this doesn't seem to fix the issue and I also don't use whatsapp/telegram voice/video calls, so I don't think is is quite the issue.
There's probably something else preventing deep sleep, but I think that waiting for an update from Samsung will be my best bet

That's interesting. There are over two dozen people on the s10 page confirming this to have solved their drain.
For how many days have you had your device? Mine took a while to understand my usage pattern
I am currently getting over 5 hours SoT over 18-20 hours now, it was ~3 hours previously.

I'm having the same issue. No video calls and still losing ~2% per hour. Restart doesn't help.

Mine too, lost 3% in under an hour sitting in my pocket doing nothing. As usual the battery stats are not much use.

There's a bug with the proximity sensor. The phone gets turned on automatically in the pocket which might cause battery drain.
BTW putting the phone on battery saver (Medium power saving) mode stops battery drain. Until we get a fix from Samsung this seems like a worthy option.

Nope. It's not only when sitting in the pocket. Basically put it on a table and the battery will drain.

There's people on the S10 forum reporting a much better battery performance after a software update (ASC8) on the Exynos S10 / S10+ (see here or here) that should fix the drain issues. Do you know if they are rolling it out also for the S10e Exynos?

It seems ASC8 has been stopped, and they are releasing ASCA. For now it has only released for Germany firmwares. Let's see what's new in this update. Regards

Same issue
I have the same problem, when phone is in use it gets great SoT of around 6 hours, but when not in use throughout the day battery still drains very quickly. I was hoping the update will fix it , but even after updating, nothing changed. Hopefully there is a solution soon.

Seems like battery drain issue was fixed in the latest update ASCA. Mine was previously draining 15% overnight. Now it only drained 4% in 8 hours!! Which is pretty amazing.

Anyone have the Hong Kong model G9700? I've noticed standby drain is quite high.

I have German ASCA version, but battery is draining awfully. I use both SIM cards and loose 25 percent half a day being in standby-mode.

Expected at least 5 hours of SOT from a phone at this price point. This is bad. Even with the second sim turned off, battery drains heavily.

I was also having pretty bad battery drain, 15% overnight. But after the ASCA update I'm getting about 5% overnight, maybe it's just my phone?

Used this guide:
https://forum.xda-developers.com/s10-plus/how-to/galaxy-s10-battery-optimisation-guide-t3911988
After i made the tweaks the standby is decent compared to my OP6

I disabled bixby on the Maine screen 4 hours ago and I do have a feeling my battery od much better. Will see...

ASDA update seems to help with drainage for me.
Using 970U1 TMB version. Attached is typical usage for me last few days. I get another 6-8 hours sot average by 15% or so and about ~5% overnight drain

Not sure why the "Android OS" always so high usage, I think in normal case, it should be lower than "Android System"..
And by using Battery Historian, I saw this kernel wake up, does anyone knows what's that?
I'm having a lot of RILJ_ACK_WL too.. Sigh.
