First of all, I am new to Xda so I am not sure if this is the right section for this post. So let me start. Bought this device from samsung last May here in the Philippines. Everything worked fine. I rooted it after a month and re-flashed the stock firmware from sammobile immediately after rooting. Nothing changed. Battery was so good. Last august 12, I flashed the first ever nougat firmware for a520f, the russian firmware. Battery was still good in the first 2 weeks but after that my phone keeps draining battery like hell while doing nothing!! I ignored it for a while coz i thought that its just a bug or the battery was not calibrated properly. But after a week, I got worried. I sleep with 100% and after I wake up, only 65% was left. It drains 5% an hour and it's pretty awful. I couldnt enjoy my phone especially after school. I go home with only 20% or below with 2 hrs SoT. Couldnt resist the problem thats why I did a full factory factory reset including the cache partition. Was excited after resetting coz i thought the problem will be fixed but unfortunately, it wasn't. I was confused and didnt know what to do thats why I flashed a different firmware. The Cyprus version of Nougat. But still, the battery drain is still killing my device. After 2days I flashed the Indian version of nougat and STILL NOTHING HAPPENED Phone still drains 5% every hour. Did everything I could. Rollbacked to marshmallow (ph firmware which was my original firmware). So im back at mm and im hoping that the drain is gone but still, it's killing me. Dont know what to do. I updated my a520f to nougat via OTA. But still nothing happened tried rooting, still nothing. I really need help. I think there is a bug in my phone's deep sleep mode that causes it to be awake even when the screen is off. Please help me guys. I did everything and the batter drain is killing me!!
Ps: i tried safemode, ultra power saving and more stuff but still the battery is drained while idle.
Note: Battery is good when im using the phone

Today I had my AT&T One X at around 40% charge when I went to sleep. After getting up the phone had shut itself down and when I try to turn it on using the power switch nothing happens. I charged it then it starts charging from 0%. I am on stock 4.04 rom and have rooted the phone. This is the third time in a month that this has happened. I am attaching the battery curve that I got after today's incident. Please Help! Thank you very much for any help in advance.

Sounds like bad wakelocks, install Better Battery Stats to find out what is draining your battery.

I have installed betterbatterystats and will update with results next time it happens..
I too am having this problem. Though it started happening after my phone drained and wouldn't restart after charging (boot loop). After I fixed that, it's been dropping dead.
I'm on a stock rom with ElementalX 3.0 kernel. Was v2.0 when it initially started.
Any luck finding information? I still get about the same use out of it (sometimes). I'm thinking that maybe the battery's level is getting reported incorrectly?
This is a known bug, whatever the hell is causing it. Just about everyone has had this happen at least once.

How often are you having this problem. I have had this happen about 3 times in the last three weeks or so. Since my post last week, I haven't had it happen to me yet. I now have the betterbatterystats app installed and will update with results the next time I have battery drain.

It happens quite often. Happened today, then three days before that. I really don't have much on this phone either. After the initial bootloop I did a factory reset and didn't really add much.
This happened to me once on stock rom and kernel. I think it has something to do with the network trying repeatedly to connect and draining the battery. But the phone is asleep and not updating the battery percentage. When the phone finally awakes, it instantly updates the batteryfrom whatever it was before to 0. It seems to happen to people in the early morning.
There is a pretty sizable thread on this already.

I have contacted AT&T and HTC. Neither knows whats up. Went to CM 10 though and haven't seen the issue. Although, the last 2 weeks with CR Dev I didn't see the issue either. It used to happen every night.

Thought I remembered seeing a thread but couldn't find it via search.
I wonder if it's a sense based issue if you haven't seen it with CM 10. Though I didn't have any issues while using the stock kernel. -edit just read flar2's post about using stock and seeing the issue
Most likely something is draining while the phone is asleep and the battery doesn't update. You can see in my history details that when the phone wakes it jumps. Especially the ending death jump lol
I know if I have fast boot enabled and then it off, it'll drain around 10%. It only loses around 3 or 4 if the phone is shut down. I've never left it on overnight, but then again I am an avid task-killer

I have a 20 day old galaxy s6 duos. It was bough new off ebay. I was functioning properly and when on holiday I dropped it onto a tiled concrete floor from a height of 2-3 feet.
Since then the battery has been draining abnormally.
I have disabled apps still no joy. Then ran the phone in safe mode with no improvement. Then did a reset using software with no improvement. Then wiped cache but still no joy. Then wiped cache and hardware reset. Finally disabled all apps and forced stopped a few more. Put the phone in airplane mode but despite that the phone is drains 10 %per hour with the phone not being used.
No apps running on the battery usage screen the only thing shown is device idle 1 %. .
I cant understand how dropping the phone can cause the battery to malfunction . Any ideas or suggestions ? Or something else I should be trying.
I wish it was easy to change the battery but that is not the case . I just wanted to see if anyone else has suggestions before I go down the route of replacing the battery.
Many thanks in advance.

Try flashing stock 5.1.1 ROM via odin.
Thanks for the reply, It is already running android 5.1.1 baseband version G920FXXU2BOFJ . I dont understand the rest.
Do you think it worth reflashing the phone still ? Happy to provide more information.
Hi guys
Just got a Galaxy S7 today, and when I first turned it on it had 61%, I started doing the setup and everything (I was out and on 4G), noticed that the phone's battery drains so fast (like 1% down every 2 minutes or less), by the time I finished the setup it was down to 40% and it was so damn hot.. I let it cool a little bit then I continued installing all my apps and doing all the updates when everything finished it was down to 20%, I said ok maybe I need to update the system software for it to be good, so I charged the device a bit while the software update gets downloaded, updated the phone and left it there for a while charging. Now it's 60% but even then when I use it just for a little bit organizing apps and getting everything ready, it drains fast and gets hot.. I have location disabled, NFC disabled, apps battery optimized, disabled all bloatware using package disabler pro..
Any solution guys? Should I just keep charging it and discharging it for a couple of days and it will get better? I don't understand since from the reviews everyone is saying that the battery life is fantastic.
thank you
Test it out for 2-3 days. If the Problem still exists try a factory reset. Good Luck

Okay I will be patient for 2 or 3 days and see of it becomes better, otherwise I'll try a factory reset.
Thank you mate
Bro i have the same problem as u you have
Did you find amy solutions its been 2nd day thanks !
Hi,
I owned a Huawei Ascend Mate 7 Gold 9 months ago, and I was very happy because I could use the phone for more than 2 days withouth charging. But recently, the battery started to drain VERY FAST .
For instance, if I go to sleep with the phone at 100%, when I wake up (8h later) , the battery is at 70% or less. With my investigation, I tried/found that:
-The problem is not caused by deep sleep mode, or at least "CPU Spy" shows that the phone is able to do it.
-I tried wipe (factory reset/partition/cache) with no results.
-I calibrated the battery but the problem persists, also I tried charging with 1A charger.
-"GSam Battery Monitor - Root" shows that 47% of the battery goes to "Android System" and another 20% goes to "Kernel (Android OS)".
The issue started at the last week, and the first thing I did was updating Lolipop (I was using it for more than 4 months) to Marshmallow 6.0 (B561). I don't know what do to now, ATM I'm underclocking the CPU, but that's a temporally solution. I always take the battery with a lot of care, I don't know why is happening this.
If someone could help me, I will be very thankfull .
-FULMI
same here
i have exactly the same situation with u and couldn't find a solution yet.
battery issues too
what firmware you running? I have an EU version of the phone, updated to 5.1.1 and it was dying fast. I then updated to 6.0 Malaysian rom from their website and it started to do the 2 day life. However the phone seems to just freeze and sometimes just switch off, so I am thinking of downgrading and then see if its the software or its a hardware failure. I have warranty
I couldn't find any solution yet, so I'm going to downgrage to the 4.X. I don't see benefits from Marshmallow update, also I can't hide the taskbar, so...
Actually I think I'm using CH version B561.
Edit: Fine, I can't find a downgrage pack for my version.
Sorry if the question has been answered before but does anyone else get a lot of battery drain due to 'phone idle'. I'm unsure whether if deep sleep not working or what but have never had this problem with any other phones I have had.

Yes, I'm definitely experiencing the same problem. I left the phone overnight and it lost almost 7% which is a lot compared to my old Z1 (only 1-2%). Other time is also similar. Sometimes, it feels like it as if actively using the phone actually uses less power than leaving it idle. Looking at the battery chart seems normal but the phone actually discharges fast on standby (sometimes I lost 25% after just 4-5 hours standby) I'm really want to know if others experience this as well and how to fix.
Yes I'm having the same problem.. Phone idle taking more drain than screen right now..
It's deffo a bug with this 7.0 update.. Hopefully it gets fixed in next update..
My battery sucks now after the Nougat update! Drains really quickly on standby. I even turned WiFi scanning off but it didn't seem to help
I am facing the same issue too
Phone idle appears at the top of the list, claiming 135 mah
While my screen states its using 49 mah
Similarly and annoyingly. Since Nougat my phone barely deep sleeps.
My phone was deep sleeping amazingly on mm. But now it barely deep sleeps. Ridiculous update which now requires me to perform a clean full wipe install of Nougat. Which currently I have no time for, hence my battery dies ridiculously fast. Annoying and not what I was expecting, this removed my excitement away from receiving the new Nougat update and instead am left with work to do to get this one back to par.
This has happened to me before on previous Sony phones when installing new ota updates. Clearly something Sony is good at.
For the OP - this is one of the best apps to determine CPU behaviour, simple and to the point. Particularly scroll to the bottom to obtain how well or not the phone deep sleeps.

Since upgrading via OTA to Nougat my device barely deep sleeps, rather it sits at 307mhz when idle. Battery gone to sh!t. Forced to do a factory reset fresh installation (when I get enough time to.)

Thanks,
It's seems the idle just stays on all the time even if the phone is being used..
Sony needs to release a patch for this asap..

Clean install, locked and unrooted, DRM in tact?
Still unfavourable deep sleep?
Then that surely is pointing to a inherent issue with Sony Nougat.
However why isn't everyone here with XZ Nougat complaining the same?
We need more input.
In the meantime I will need to bite the bullet and reset my phone as well and report back.

Been using kernel auditor to check usage. Will reset it and will use the phone as normal tomorrow and report any findings.

I got the same problem with you too, 7% after night, my old phone was Z1 to compare too. After update to 7.0 then back to 6.0.1 battery drain is less, but still more than normal.
I also Started to get huge Phone Idol drain (top of battery usage) after OTA update to Android 7 on Stock unrooted, Ive done a complete fresh start through xperia companion and still getting big drain from Phone Idol.
Got the same problems you guys are facing.
My phone did drain from 100% to 88% in just 2 hours (Display on: 35 minutes half brightness, phone calls 10 minutes) and its on WiFi not even mobile data. My girlfriends phone did drain about the same with 35 mins display on BUT calls of 45 minutes.
Oh and idle yeah on WiFi about 1% every hour and on Mobile Data 3%/hour.
This is really bad imho and it's been 2 times I've repaired the device via Xperia Companion. Funny about this is, that always on the first run I get a message "Firmware could not be repaired". Then I restart the whole process and it does just fine. Same with restoring images/videos.
I've started to notice my phone idle is near the top of battery usage. Initially after installing Nougat, battery life was great. Now I narrowly get 5hours of SOT. Currently at 70% and phone idle has used 19% of battery at 196mAh and SOT 1.5hrs with 182mAh. Not sure why the phone is not sleeping.

I upgrade to 7.0 again recently, and it only cost 1% per night, it's quite good . But battery consume while using is not much improvement like idle.
Facing the same problem, though i dont think its actually draining in my case, the phone deep sleeps fine but the drain with screen on is just appaling, since I got it I only got 4 hrs Max SoT thats with MM and N. It just seems that the battery generally sucks.
As of now, i have 84%: sot 23% 48 min - phone idle 20% (time on 4 h 35 min). By this it means i'll get about 3.5 hrs SoT which is normal in my case (though not good in my opinion)
I've just updated to the lastest .374 from .327. From what I experienced, the standby battery life have improved. I left it overnight and it only lost 2% (unlike 7% like before) which is probably ok for now.
Do you want to say.....that leaving the phone all the night....it lose 2% only???? I can't belive....normally it goes down by step of 2/3% for hours....so in 7/8 night you have to lose at least a 20%....minimum....
Well my battery result probably need more testing but it has never lost up to 20% per night. It would be outrageous if that happens. Are you sure there isn't anything that continuously running in the background of your phone? You could try a factory reset? Usually losing that much of battery per hour is only when the phone is actively being used, I think.
