Hi Guys
I'm currently on Stock Android w/ Franco Kernel, Rooted and as I was watching my battery level closer after the first few cycles, I noticed that Cell Standby was making up a huge amount of my battery consumption.
In BBS I personally don't see anything reflecting that, but as you see in the attached screenshots Cell Standby consumption is huge. I've never experienced something like that with my former phones. Could the reason be, that I have bad reception over the day?
Any sugestions what I could try to fix that?

I'm having the exact same issue. My cell standby is at 49%. I can't even go a full work day without charging it (something I didn't have to do with my nexus 4).
I've turned mobile data off for now to see what's going on. I have friends with Nexus 5s and they're getting pretty good battery life. I might even erase my phone and start over again to see what's going on.
That's weird. Have you tried reflashing the kernel? Not sure if that'll really matter or not, but it would be worth a shot.
What is your Phone Idle time showing in comparison to your screen on time and standby time? I'm just really surprised your WLAN is showing as off. I take it that's a fix related to the kernel too? Mine is always on no matter what I do (I'm running stock though).

Yes, I tried reflashing the Kernel, but I guess it's not kernel related. Tonight I fully charged it and took it off the charger, and left it there for four hours. (Screenshots attached) I have Mobile Data always on, and WLAN (as I've currently no WLAN router here) as well as Location Services always off.
Everything seems about right, just the Email-sync is a little bit off the charts in terms of wakelocks. The next things I'm going to try are disabling email sync, then switching radio, and if nothing helps, a complete restart from scratch with a Factory image.
I understand that when there is poor signal the cell standby is going to drain but this seems to be a bug. Once I return to good signal the cell standby shouldn't continue consuming battery. If I forget to put my phone into airplane mode before I go into the hospital the bug will drain it no matter if I get back into good signal area shortly after. If I get into airplane mode before the bad area and turn it the radio back on after leaving the area, my battery lasts fine the rest of the day.

I've been using the latest ota 44s rooted, but with no modifications. its probably the most stable yet. no issues apart from this. despite the battery being actually quite good, i get 6+ sot within 40+ hours. but i'm getting an issue where according to the battery monitor, it drops a few percentages in one go without me actually using the device. its still on deep sleep. no wakelocks or anything like that.
Could it be that the battery stats is not being monitored properly by the phone? where the phone is going down steadily and then it realises the battery is at a slower percentage than its already displaying?
or is it something else?
This has happened to me several times previously. though no reboots, and battery life is still good.
as you can see here it drops from 86% to 77% whilst the -mAh is at -9mAH
Use a app such as better battery stats and debug your apps. There's most likely a app causing the phone not to properly deep sleep

i used to use bbs, but then found wakelock detector easier to use. if i install v2.000b7, do i just go into the advanced setting and add debug info to logcat?
Re: Phone deep sleep battery drain
I have also come across the sudden battery drain issue this past week. My phone deep sleeps well and I can find no wakelocks. It appears to use excessive battery when idle. I have tried a fresh, blank install of CM11S 44S and that didn't resolve the issue. I have since moved to Cm11 nightlies and that slowed the battery drain but I am losing 12% battery per hr when idle and the phone is staying warm. I do not understand how this happened and why it just spontaneously began. A fresh install with no additional apps, and no problems entering deep sleep. shouldn't be doing this This phone was brilliant for battery life and I cannot work out how to resolve this.

I have checked that and it appears to be sitting at the minimum 300MHz as far as I can tell. Since posting I have tried PA 4.6 for 24 hrs, no additional apps, and now I have moved to Liquid Smooth Lollipop nightly just to see how they compare. Even changing radios doesn't appear to have any impact on the power consumption.
When using GSam battery monitor on both the CM11 and PA (both behaved similarly) my phone was using anywhere from 500mA to 800mA (minimum screen brightness) for no apparent reason. I am unsure what usage this phone should be to be honest but I think that is high.
On Lillipop, the category 'Miscellaneous' is by far the greatest usage category and is seeing 2-3 times expected mAh drain compared to its computed usage, though I am unsure how that is worked out.
The most my phone will last now is 8hrs standby, in deep sleep. I am beginning to wonder if there is something wrong with the hardware of this device now. Perhaps the power regulator... Not sure what test to do next TBH

The next thing I'd do would be a complete wipe and flashing the fastboot images. This still return the device to a completely stock state (including wiping the user data), leave it like that (don't install any apps) and test for a day or two.

Before flashing the CM11 Nightlies to see if they rectified the issue, I had downloaded and clean flashed the stock 44 image via fastboot but the issue remained. I shall re flash it though and post back...

Fresh install, data off and left to own devices for a few hours and it is deep sleeping like you would expect, but a neat linear drop in the battery of 10-12% per hour as before...
I saw the same type of behavior while running CM11 based ROM. At night, I would put device into sleep (no data/no wi-fi/no sync/etc.) - basically everything off. In the morning, it would still show 100% - but then quickly drain several percentage each minute for the first 10 or so minutes. It was like it was catching up to the correct %. I have used wakelock and BBS and nothing sticks out. I also set Google Play services to stop wake (which did help battery life a lot).
Does anyone else have the issue where android system is consuming 35+% of the battery? Looking at the stats it seems like one of the bundled services is keeping the radio on for 14/18hrs its been on.
Have the same isssue
Yeah, I'm having this issue too. Android System is consuming HUGE amounts of battery for me.
Thought I was the only one but glad that's not true! Still got good battery stats with the android system drain nonetheless.
Charged mine to full last night right before hitting the sack.
Woke up 7½ hours later and it had consumed 33% of the battery just sitting doing nothing bar getting email & polling (presumably) for Facebook updates.
And that was with Power Saving enabled. Bit disappointing, hoping when I disable auto-sync that it'll kill the drain.
There's lots of services running under Android Systems disable the ones u don't use, I have disabled some got better battery life, still testing some others...
The hardware on the phone is great, but touchwhiz drives me up the wall. I'll be happy if and when we get anything AOSP based, CM being the holy grail. Nice to know I'm not the only one getting this battery drain. I've disabled pretty much everything that's able to be disabled, as all I use is google services.
Same problem here.... Huge Android System battery drains.
I've played around with several things, and as of yet I haven't gotten it to stop other than turning off WiFi. Anyone found a fix?
Mine's more a combo of Android System and Google Services... both take up a majority of my usage... Services typically being a bit more.
Why are there two android systems? wtf...
Is there any way to reduce cell standby?

Same sh*t here. Went to bed last night fully charged, and 7-8 hours later, wake up with 23% of my battery gone.
I'm starting to wonder if moving away from the Nexus line was a mistake. I started running again and the N6 was just too big to lug along with me, on arm or in a waste band, so I decided to try Samsung.
Just got my S6 and I noticed this right away. Last charge I had 2:42 of SOT and "Android Systems" used 47% of the battery. I was just watching Netflix and YouTube mostly. My overnight drain is also quite high, about 1% every 30-40 minutes of standby.
Is that normal for most S6 owners?
To all:
Turn off VoLTE, turn off WiFi calling, install CPU Spy, ensure your phone is going into deep sleep. If it isn't, flash the stock recovery with Flashify, wipe the cache with it, then flash TWRP back with Flashify.
Post your results.

This is for everyone. If you haven't flash TWRP, then simply wipe the cache with stock recovery.
I just assumed most people would have TWRP flashed, my bad.
I am guessing that that this is an Android problem as the Galaxy S6 Edge has the same problem with battery drains.

I'm not rooted and I don't plan on doing so. I'm not sure of any other options. I unplugged it last night an let it sleep. Android system used about 14% of the battery. And I lost 20% charge. Cpu run time was 38 minutes too. and I never even woke it up post unplugging it.
I believe this Battery Drain Issue is a Lollipop issue. Was haing it with my One Plus One, I fixed it by going into privacy Guard, and going to Google Play Services and not allowing it to stay awake, and start by itself.
Ill find the actual thread and post it, same issues happening with a lot of phones using lollipop
Battery drain on a new device = bad flash (very common on android devices, first run)
1 wipe the devices and start it again from factory problem should go away. (at least the excessive drain anyway)
2 Ensure you have updated the Samsung Services app (this was responsible for most if not all battery drain issues if you reset your device)
3. Turn the bloody Screen brightness down and turn off Adaptive display (way way way too much battery drain using them)
4. LTE off and Cell data off if you on wifi, your wasting battery power communicating with cell sites you arnt using, the weaker the signal the more power you will drain for no benefit
6. GPS / Loc data off unless you need it even then wifi / AGPS is usually more than accurate, remember GPS + poor sky visibility = more power used to get a loc.
5 NEVER measure battery life for the first 24 hours way too much stuff syncing and updating to measure with any accuracy.
I get a solid 2 days out of the S6 with mixed use and a screen on time of 2:30 could get that upto 3 hours but i have a hearthstone addiction
As mentioned above, I highly recommend wiping the cache, even when not rooted.
Also, worst comes to worse, i'd completely redo the phone from scratch via the Smart Switch software samsung provide.
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.)

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.

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.
Hi guys. I have a problem regarding heat with my g930f. After updating to Nougat the phone started to heat in the area of power button. It doesn't matter what app I am using it randomly starts to heat. The device is rooted and now running Superman rom with super stock kernel. The battery is draining like hell when the heat occurs. Installed BBS and monitor what is causing the drain. In most of the cases says Android system and/or wifi. What I noticed is that I can't fully turn off the wifi. It doesn't matter what the icon shows - off or on, BBS says that the wifi is 100% of the time on. Besides the device goes to deep sleep normally and when is in that state the battery drain is very low - 2% for 8 hours. The SOT is no more than 2 hours which is very bad. Tried stock rom, superman rom there is no difference with heating. The most interesting thing to me is that the heating problem occurs randomly - scrolling browser, watching youtube, playing games, listening music - sometimes it happens sometimes not. Still didn't tried to rollback to MM but frankly I don't want to. I just like Nougat. Any suggestions or ideas what to do will be appreciated. Cheers
Wifi might be locked on due to location services. Connections->Location->Improve accuracy.
Otherwise the low SOT suggests somethings hogging the CPU. Did you factory reset when you upgraded? Have you tried seeing if this happens in Safe Mode?

The location services is set to device only. Yes, I did wiped everything couple of times before and after install. And yes did happens in Safe Mode
No one has any ideas?!
If it doesn't stop even after a full wipe and firmware flash then it might be hardware damage? The heatpipe is in the right of the device, so that could be damaged maybe? It doesn't explain the battery drain though.

I read heat can make these batteries discharge faster when it gets to a certain level, don't know any details though. Maybe it's worth checking out.
