[Q] Battery Drain: Have To Shut Down Every App?

In a previous post I wrote about an issue I was having with battery drain, that I was somewhat able to fix. After switching over to FI03 I noticed the drain wasn't so bad but obvious. The only way I can get a full days charge on my phone is to go into task manager and close every application before I put my phone in stand by and set it down. Surely this can't be right, isn't that is what stand by is supposed to do, suspend those apps I was using until I wake the phone again? Maybe there's some other app that will do this automatically, or some fix I'm missing. I know there's a million "battery drain" threads, I'm just wondering since I've isolated issue and am able to recreate it, is there a way to fix it?

Just use the kies update FH13

UPDATE: I found again, as in my previous post I mentioned, if I remove the SD card I'm not getting the battery drain, I can even leave all those same apps running like previously. So I'm getting two different things that are solving my battery drain. How can I diagnose the issues based on the two resolutions 1) shutting down all my tasks before I click the home screen off and 2) taking my SD card? Between those 2 issues it should make it easier to figure out what the problem is. Any ideas?

Use programs like better battery stats and system panel lite to narrow down the problem. A fresh installation from scratch always helps too.

Thanks for the tips, anyone else?

Put your SD card back in your phone after backing up anything you want to keep from it, and format it. It should fix your battery issue. There is a bug with our phone (maybe other phones?) with the SD card causing battery drain.

Horrible battery drain :(

I've been having horrible battery drain recently -have no idea what it is, but I have this wake lock so I'm assuming that it's the culprit.

Wakelock detector, under wakup triggers, shows Android system (82 times) and Google services (28 times). What could this be? Good god.

It's not a permanent solution but you can install "firewall for Android" to block any communications(except phone & sms). It has a widget to quickly disable the firewall when you need it.
It might solve your battery problem until you find the real solution.

This could be kernal issue. I see that you are using dual boot option with Devil kernal. If possible try changing the kernal (you might need to move to a single boot) and check on the battery drain.

Nope, no dice Disabled everything, and still it's there.
What's weird though - I've done a clean install of ROM and flashed a different kernel, and still the problem persists. Ugh.
It just refuses to go to deep sleep - otherwise I could've assumed that it was just the battery damaged or something. Annoying the living hell out of me.

You can always try "ROM Cleaner". It will remove anything you don't choose to keep. there's a good chance it will remove the culprit in the process(make a backup first)

Rogue APPS. install GREENIFY. works so well... also if you want to find out what is waking your device. better battery stats app is also the bomb!

Ok guys im fairly advanced at this, so I've absolutely covered all bases. I've installed greenify before itself. And i even did a clean wipe and reflashed the rom. I've now restored a nandroid when there was no drain and it still stinks.
I see that this is associated with external sd damage maybe but i don't have it in at the moment.
The only thing I'm yet to do is a factory reset.

Solved it - those were of no use, finally had to do a factory reset.Gave me a torrid time
This terrible mmc1_detect wakelock draining about 3-4% per hour even with sync, wifi etc. off. And lots of searching didn't help either, and saw that many other users have had the same issue. So just creating the thread for those who've had this wakelock all of the sudden from nowhere and can't get rid of it.
From searching a lot, I saw that it's most likely caused by a corrupted external SD card - but I don't have an external SD (as for now) so if you have, format your external SD first and see if that works.
If not (and this is what happened in my case), apparently some of the files on my internal storage were corrupt, and that was causing the wakelock. So I did a factory reset and restored my previous nandroid backup. Everything works normal now
I hope this helps someone who faces this issue in future.

Okay scratch that. Didn't work at all
For crying out loud. Anyone have any ideas?

Any solution to android system battery drain?

It's killing my battery just as much as the screen is. Android os is always the 3rd culprit. I've tried uninstalling Google services erasing cache reinstalling then rebooting, that did nothing. I tried keeping GPS on in battery saver mode that helped but halfway thru the cycle it started back up again. I'm not gonna bother calling vzw because of course they'll act like they've never heard of the issue before and just tell me to do a factory reset which I've done. Oh yeah this phone is a replacement my old one died last week and also suffered from this issue also

Do you have an SD card in it? Try backing up the data and formatting it with the phone. See if that resolves it. I had insane battery drain issues on my phone, ended up removing the sd card altogether and haven't had any battery drain issues since.

The only way to really see what is going on is to use an app like GSAM battery monitor to analyze what is draining your battery. You will get much better insight when you root. I was able to identify apps that drain my system, and then either uninstall them or greenify them. For instance, I noticed that the MyFIOS app drains battery like crazy, uninstalled it. I have a Polar watch, and the companion app drains battery, so I greenified it. Also, turn off all the background synching, scanning, location etc, that helps quite a bit.

Media server Battery drain

Hey guys, im currently using the exynos variant of the note 7. I've faced significant battery drain and have already trained the clear cache and factory reset method. Getting better battery life but found out that Media Server is still draining my battery. I have tried disabling chrome, unmounting and removing the sd card, I cant find media server in my applications to force stop it. So i really have no idea what to do next, media server is still the highest running on my battery usage. Anyone else facing the same problem? Any idea what to do?
Im new here so i cant post any images or links. But its at 25% at the top.

It's trying to read your memory card. But it should go away after 15 minutes of inserting the SD card. If it keeps going then there is something in your card it has a hard time reading so it keeps trying. You may have to move your stuff out temporarily and then reformat the card with the phone. Then copy everything back.

Wow really? That's new. I think it's time for a factory reset. It will probably fix both of your issue. I know it fixed my battery drain problem. Run it for a few a few hours without installing all your apps. Install as you need them but don't restore it's data from another back up. Start from scratch.

It's possible I have some corrupted files in my SD card. Will try reformatting it and then reporting back. I've factory reset my phone too many times already.

I have an s7 and have exactly the same issue. Some people have drawn a link to chrome and browsing on media heavy websites. Which for my own use actually makes sense. Phone would stutter on XDA etc get super hot, media server would be top battery drain, then phone would crash horribly and be unresponsive. I switched to my Nexus 5x today. But after now learning it could be chrome I'm gonna give my s7 it's final shot

Same problem here. Media server sometimes draining 35% of my battery.
I've no SD card.
Heavy use of chrome.
Will try ditching chrome for a couple of days before resorting to a factory reset.

Have you guys tried greenify? Even if non root it works great. I set it with nova launcher to run greenify and lock screen and turn off when I double tap.

Hi amigo,
OK so from when I sent that original message to today, I did what I read, and stopped using chrome. I only use Samsung internet - which is actually quite good - and the issue hasn't come up once. My phone hasn't crashed, or even got hot once.
From this, and my own experience I'd be confident in saying it's an issue with the Exynos processor and chrome.

This is often caused by Google Photo's or Dropbox or any application that automatically uploads your pictures/videos/files to a cloud service. I have found that this either settles after a few days or you might have a lot of large files constantly changing.

Thanks - sounds hopeful ?

Was trying to figure out why 4 hr screen time was all I was getting. Only heavy chrome use and some streaming to Chromecast. Used to get twice as much from my note 4. Disabled chrome, started using samsung internet and surprised at how much faster it Is, amd smoother.....
Giving it some juice and will try again. Thanks for the advice.

high drain from cell standby sounds like bad reception.
last time a cell tower went down in my city all phones dropped to a standby time of 5-8 hours.(just standby, so not even turning the screen on once)

Interesting. I've always had a problem with battery life and I live in an area of bad reception...
What's the theory behind this? The phone spends power continually searching for reception?

multiple reasons.
1: the further the phone needs to send a signal, the more power it sends to its transmitter.
bad or no reception means it needs to send at full strength.
2: while trying to search for a cell tower the receiver/transmitter is constantly working overtime, drawing power similar to what it would draw in a phone call.
3: while the receiver/transmitter is busy, it's also keeping your phone's processor awake.

In 3 hours of standby I have lost 3% of battery after disabling chrome. ...now 4%. The phone is like an ice block too, yet it was always quite warm. I used to lose 7 to 10% per hour which i was putting down to the phone learning etc.

I had the same media server battery drain issues. I narrowed my issue down to chrome. Used ez package Disabler to stop Google chrome and am now using Samsung internet and my battery drain of media server is gone! It's unbelievable how much another scrolling is with Samsung internet browser over Google chrome.

Quick update: having ditched chrome my battery is behaving beautifully. Lasting all day and with five or six hours screen time.
Media server still crops up but it's using 5% rather than 35% of the battery.
Obviously I don't know for sure that chrome was to blame.

Thanks to all those who gave advice on this thread, btw.

If you want to keep using Chrome you can try rolling back to an earlier version (uninstall updates) it seems to be a recent update causing the issues.

I'd like to give Samsung Internet a go, but Chrome has all my log in info and password for websites. Is there a way I can import that info?

Battery Drain following Oreo Update, even after update to Oxygen OS Open Beta 5

I have a Oneplus 3 and I have been quite happy with it .. up until got notified for an update to Oreo a few daya ago.
Since the update, the battery drain on the phone has been pretty bad and even when I am not using the phone, the battery is draining much faster than it should or was.
Yesterday I tried searching on Oneplus forum to see how to fix it, and saw some post suggesting to update to Open Beta 31. I downloaded the update the manually updated the phone, and the battery drain still seems to be same.
Fyi, my phone is not rooted.
Please see the image below for battery drain graph..
What I can see is that even when the screen is off, and the wifi is inactive .. the phone is still awake and not seemingly going into deep sleep mode..!!
Can anybody please help how to solve this issue?
Thanks

you could try better battery stats although it is a root app to find what is keeping the phone awake, i think you can use adb to grant the permissions for it to work without root or you could factory reset that should sort it out

From the screenshot, I am able to see that you have a very patchy mobile signal which is one of the reasons for the drain .

Well, the signals have been same even before the update. The battery drain was not like this before.
In the last 8 hours, with little use the phone went to about 36%..
Now I can do a factory reset but it's an annoyance because all my data would get lost, or I'll have to backup and restore using some means.

I have noticed that with an incremental update, things get sour on OP3. The best bet without losing data would be to clean flash the full ROM after wiping system, data (excluding internal storage), Dalvik and cache. I am sure your issue would be gone.
I always clean flash and have no such issues.

100% App related. I am getting great battery life on Oreo 5.0.1 by using Greenify. Maybe 3-4% overnight.

Just because it worked before doesnt mean it will work the same after an update. Mainly with this OEM.

Hi,
I've tried clearing the cache and also deleting everything except personal data and reinstalled the update 31 multiple times. Still the same problem.
The battery is draining at about 10% every hour regardless.
Can anyone advise what else can i try?
My only doubt now is if the update 31 file is the right one to install. I'm assuming that because the file is approximately 1.5GB it is a full update rather than a incremental update.
If that's not the case, can anyone tell me which file to install as the full update?
Another problem I have noted since the update is that the Camera does not work. Not sure why though.
If nothing else works, I'd be forced to try and downgrade to android 7 though I'd prefer to have android 8 - if it works and does not drain the battery this much.

You say that you have the OP3 but the heading of this thread refers to Open Beta 5 and then you say that you clean flashed Open Beta 31. Which is correct, OP3 or OP3T, OB5 or OB31? No wonder you are facing issues.

Hi
The phone is Oneplus 3
It prompted for auto update to Oreo, which I did.
Then started battery drain issues.
After reading forums, I updated to Open Beta 31.
The battery drain is still there and I have reinstalled Open Beta 31 couple of times which includes deleting everything from the phone excluding personal data, music etc.
I have cleared cache as well.

I repeat, your mobile signal is one, if not the only, heavy drainer.
Install BBS, grant permissions through adb, run it and take an idle dump (as described in its thread) and attach it in the BBS thread. Someone there will study it and identify the culprit/s.

I've installed Bbs and here's what it shows:

It shows something named video2 is keeping the phone awake most of the time. I also found that the phone cpu is awake most of the time rather than being in deep sleep.
Looking on the internet, I can't find what video2 is!!
Any ideas?

Also just found that the YouTube app is also not working. I google'd and found many people have reported the same problem, and have been suggested to do a factory reset. So I've just done that as well and it has still not helped.

Here's another screenshot of betterbatterystat showing the same issue :

This shows that the phone is not going into deep sleep most of the time, as video2 is keeping it awake. Hence the battery drain.
Any ideas of what I can do to solve this please?

Tried a reboot? Don't use any force dozing apps or block wakelocks.

Yes, rebooted the phone and I am not using any app to restrict wakelocks or force dozing any apps - apart from what's inbuilt in the Oreo os.

It's known that Mobile Data can be a really big drainer. I easily go from 0.6% per hour on WiFi to +2% on mobile data, especially poor signal as you have shown can drain even more. You could try using Greenify with Shallow Hibernation, it doesn't kill apps it only restricts them from doing too much in the background, you could try blocking the wakelock with Bluspark's build in wakelock blocker. But I am highly against blocking things that you don't know (Can cause more wakelocks, random reboots etc).

If Video2 is similar to Video3 is then most likely camera related.
Maybe some app is using your camera and doesn't even let your device sleep. Which could make sense since even being awake all the time 10%/h drain is way to high with the screen off, so probably other hardware is being used.
Check your apps, you might even have malware installed. See what permissions was each app.
I'd recommend to backup your data, do a factory reset or even wipe system partition (although you need TWRP for that
Since you mention that YT is not working another possible option is that is some playback video related.
Same thing, backup and factory reset. Install each app with Playstore and don't restore backups.
Maybe when you backup your data into your PC run some kind of Virus Scan over all the file just to be safe.
