Battery drain overnight (8 hrs, 12-15%) - Samsung Galaxy S7 Questions and Answers

Hey!
I'm experiencing high (imho) battery drain on my S7 flat (Exynos), when the device is in standby.
The problem is, i can't find any reason for this. The only thing i see, is that my phone is active very often during night. But i can't find the app/service thats causing this.
S7 Exynos variant
Android 6.0.1
SupermanROM 1.6.5
2G only, WiFi off (2nd period of the night)
Here a few screenshots:
721 Wakelocks?
went to bed at 0, woke up at about 3 to disable wifi, then woked up again at 10. About 15% battery lost. Why are there so many lines under "Aktiv / active"?
Can someone provide me any infos? Or is it just "normal" for the S7?
Thanks in advance!

Same here but i always get 4hrs+ of SOT so i don't bother with this

I get 4hrs too, maximum 4,5 .. i don't care about that, it's okay for me. But the standby drain is really bad compared my S5 (1% per 2 hours drain, nothing disabled to save battery)
Maybe i found another problem (had this with stock rom, too)
rpmd (relay protected memory block?) tries to start every 4-5 seconds, and fails:

Battery Problem

Hey Guys
i have a strange Problem
my last one plus one had a good battery life time but the sound buttons get brocken , so one plus change my mobile.
1 wekk ago i get my new phone, everything is working but the battery drain was very fast.
i decided to install blisspop with bueffola kernel tweaked it a little bit for battery saving and install BBS for wakelock detections.
I elimenate all the wakelocks that cause a fast battery drain and since that te battery drain in idle is minimal but when my mobile phone is on the battery drains 3% in 1 hour.
That's weird cause as i say i eliminate all the wakelocks that causes fast drains and use the phone most time for spotify and whatsapp.
And if i start to browse on the Internet the battery life drops even faster
So what can i do?
Am i do something wrong
or is the battery of this new phone crap and i'm so luckily to get a phone with a failiure battery?
Any suggestions would be nice and sorry for my bad english.
German or russian is better
on 50% battery i have something like 2h of screentime so i thing till 0% battery i will have 4h SOT and this is nothing (don't use the Phone much a saing above only whatsapp and spotify)
Well, to be honest, 13% in 4:30h is not "very fast" considering you had 30 minutes of screen time. Mine loses about 10% per 30 minutes of using the device, going by that there are only 3% unaccounted for which easily fit the 4h standby your device was in.
Anyway. In 4:20h of tracked time, you have 1h awake time of which you had 35min of screen time. The remaining 25 minutes can be split up in roughly 15min of AudioOutput and 10min for several wakelocks such as the proximity sensor doing stuff for 3 minutes, the phone doing stuff for 4 minutes, basically everything is accounted for. All in order I'd say.
What I spotted:
You are on Lollipop. Did you wipe after/before upgrading to Lollipop or did you dirty flash from CM11s?
Do you have the new Lollipop-compatible firmwares (they come with CM12) installed? Not sure they come with Blisspop.
BetterBatteryStats has the CPU sitting on 1500MHz for half an hour. Check whether you configured your system to stay at 1500MHz with screen on which of course would be crap, the CPU should idle at around 300MHz.
It seems you had the device shut-down and then booted. Booting up the device eats massive amounts of juice.
Android reckons 3 days of usage like that, what's not ok with that?
1. Yes i wiped it and don't dirty flash the rom befor i was going to lollipop
2. Not sure have the latest bissplop
3 Where can i check what i configured to stay at 1500MHZ , in the kernel settings?
4. i know i rebootet it once
5. The reckons of the 3 days is not true , it only affects if my device is staying in standy cause i lost nearly nothing (as you will see in the logs i posted in the spoiler.)
The first BBS log shows the Device fully charged at 100% with wifi and Mobile Data on. I left the Phone in standby for the night (8h) and i didn't lose any precent.
So after 8h standby i still have 100%
After 11 o'clock till now i used the Phone mostly for spotify , a few times Whatsapp and something like 30-50min for internet.
In the second BBS log you will see that i lost Bat.: -35%(88% to 53%) [4,5%/h] although the SOT time is only at something like 2h.
The SOT time of 4h would be total normally for me if my reckon of android would be 3 days cause this is the case on my lg g2.
Because i use the phone most of the really only for spotify.
So the main problem of my device is not the idle drain but the drain if the screen is on or spotify works in the background with screen of.
I hope that the BBS logs in the Attachment and the 3 pictures can help you.
Thanks for your help
Don't go by the sudden drop of battery percentage after staying in standby for a long time, eg. over night. The very subtle decline of the voltage over the course of the night is smoothed out and reported as 0% lost. Once you start using the device, and the change in voltage gets more noticeable, the situation is re-evaluated and the previous drop of 0% gets counted in and a sudden drop of several % over a short amount of time will occur. This is physics and by design.
As for the rest, I'm by no means a pro in reading BBS Logs but from what I see, yes you are on Lollipop firmwares/baseband so we're good. The device enters deep sleep just fine, excellent in fact. No major or irregular wakelocks seem to occur, perfect.
As for the daily usage log, I see 7:45h. Of which 4:10h in deep sleep and 3:35h awake, of which ~2h screen on and ~30min phone on. You lost 35% in that time, averages 4.5% per hour. This seems perfectly ok. This would translate to 7h awake time with 4h screen time. I seem to fail to see your problem.
Interestingly the frequency tops now at 1500MHz. Did you change something?
To take myself as an example, on my way to work, I lost 19% in roughly 45-50 minutes of playing ingress. I had about 45 minutes of screen time, GPS constantly active and of course constant data traffic. I arrived 2h ago, barely touched my device in those 2h and lost another 2%. This is more or less in line with your usage, 1-2% when sleeping, 4% when awake with screen off, ~20% with screen on. You're not happy? You reckon you had more on your previous device?
Thanks for reply and help
My goal is to have a few days with android e.g 2-3 days
SOT is not so important.
Important is that there is not hudge battery drain wenn i hear spotify cause it dosn't mather if the screen is on or off it drains hard
On my lg g2 it's not so hard
And no didn't change anything about 1500MHZ
Any suggestion ?
Greetings

Try turning off the Always Scanning for WiFi option. Also, change the Sync settings for apps you don't need to be synced at all times. And Location setting to Battery Saver.

When im at home i can pull close to 4hrs screen on . If im not on wifi the phone idle is terrible. I probably drain 6% or more per hr idling. Its hard coming from a note 4 , but i guess it is what it is.

Draining at 6% per hour is not good & unusual. But for Android 5.0.2, it seems about right, unfortunately. My N5 drained at that rate before the 5.1 update.
On my S4 with its 2-yr old battery, I drain at 3 to 3.5% per hour on idle with both WiFi & LTE turned off.
On my N5 with a new battery & 5.1, I idle drain at 0.7 to 1.5% per hour.
I'll add my battery drain rate once I get my S6E tomorrow.

This is mine on light usage. I noticed etter after a factory reset. Heavy usage is between 6 and 8 depending on wifi
I'm debating going to get one of these... My Note 2 keeps not charging and the stock battery died in 1:10 (from 50% to 1%) during a run yesterday. I was using spotify and mapmyrun.
Today is my first day after first full charge and my battery drains at ~3.5% hour, per GSAM.
I have screen brightness at little bit below the half-way mark with Auto Brightness checked.
I disconnected my phone at 6 AM and right now, it has been on 16 hrs 30 mins. I have gotten 2 hrs 30 mins SOT with 45% left.
Wifi active for 6 hrs, LTE for about 1 hr.
Screen has used 52% of my battery, Wifi 15% (5.0.2 shortcoming), Bluetooth (2%), Held Awake (0%), Phone (0%), Phone Radio (0%), App Usage (31%).
So far, the S6E is outperforming my Nexus 5 on 5.1 with a brand-new battery I swapped in on 4/1/2015.
Happy with the S6E's battery life, especially considering it's only 2600mah.
a little over 6hrs and it went from 100% to 14%. Granted 56%-23% were on a 1:43 run using Bluetooth headphones + spotify and mapmyrun mapping my way. Oddly, when I look at the battery usage, OneDrive is at 18%!
18 hrs & 37 mins off the charger with 4 hrs 8 mins of SOT. 17% battery left. I'm very happy with this. Update to 5.1 should improve it a lot more as it did on my Nexus 5.
Android System & Kernel battery usage is pretty decent. Those two on my N5 on 5.1 drains way more battery than it does on my S6 Edge.
When I'm not actively using my phone, the idle battery drain rate is pretty good - 1.9%/hour (similar to my N5, with the N5 being a bit better).
13 hrs & 9 mins off the charger with 2 hrs 20 mins SOT --> 52% battery left.
All this is without Root and my usual battery-saving Root programs.
Once 5.1 rolls out and if I decide to Root the phone and add battery-saving Root apps, I'm expecting to achieve 6-7 hrs SOT.​

Ive noticed that turning off location and disabling google now has helped my battery life a lot.
I love this phone, but the battery life is the one terrible thing. 7-10 hours seems to be the max. I might have to return it and suffer the summer until the note 5.
i'm surprised to hear about all the negative battery life issues on this phone. on my GS3, i'd lose 3-4% battery just driving to work - now I get there and still have 100%. maybe i'm just not as heavy a user, but the other day my phone was off the charger for 16 hours and I still had 43% when I got home - and that included using Google Maps for 20 minutes, texting throughout the day, and using a bunch of apps. when idle, I generally only get 1% battery drain. my only complaint about the phone is some of the UI that I can't customize, but it's only a matter of time before custom ROMs are available...
I lose 10% or more battery on the phone regardless if I'm using it or it is sitting with the screen off. When I drive the 45 minutes to work, the battery is at 89%-93%.
A 1hr run with it on my arm playing spotify/mapmyrun seems to use about 26%.
Basically, I'm always worried now about the battery dying when I'm using it.
at the end of next month, I have a 14hr+ a day for 4 days music festival where I can only charge it at night. 7-10hr battery isn't going to work for me. It seems bizarre to me that they made the best phone ever, but skimped on the battery.
drive to work today with the phone just sitting beside me, 100% to 86%.

Is your location on? I had to disable google now. Turned off nfc, advanced wifi scanning.
my battery sucks too :/
i live by the charger even more
with all the same activities that got 7-10 hours on my Edge, the Note 4 is getting 14-24hrs.
Battery is beyond horrible!
Wifi is off
NFC is off
What else can I turn off? I can't even get half day out of this POS.

I think you actually want Wi-Fi to be on. I find that on any android device I burn more battery when using cellular networks.

S8+ normal battery drain

Hello,
I would just like to ask the normal battery consumption of the S8+ when idle(overnight when at sleep around 8hrs -10hrs). I'm getting 1% drain per hour. And having a 1%drain per 3-5mins when LTE is on and doing some web browsing/messenger/fb. Is this normal?
I've been downloading some video torrents lately and i'm not quite sure if idownloaded something that may affect some apps that causes faster battery drain.

Install a batter and data monitor.
Torrents, as you know, are not very safe. So it's a small chance that you have downloaded either bloatware or even a crypto-miner working in the background that is mining on your hardware.

Overnight, 8-10 hours my T-Mobile S8+ only drains 2%, my Note 8 on the other hand drains around 10%. I'm presently trying a new app, Naptime X - Super Doze, by Francisco Franco to see if it helps with the Note 8.
https://play.google.com/store/apps/details?id=com.franco.doze.x&hl=en
Last night I slept 12 hours and the drain was only of 3%. Cellular signal and wi fi have been on.
I'd say less than 1% per hour, maybe 3-4% for the whole night (7-8 hours)

New Galaxy S7 Edge overheating and rapidly discharging.

BIG PROBLEM
A brand new, fresh out of the box Galaxy S7 Edge [Exynos] (came pre-loaded with Oreo 8.0), merely 5 days in use is overheating (gets to 41°C) and draining its battery strangeley fast (about 1% every 4 mins whilst on 3G or LTE). No apps have been downloaded from the app store and there are only a few screenshots on the phone, other than that it's empty!
I first ignored the overheating when I set it up as by default it had been charging via fast charge so it was understandable. The first day the battery consumption was "ok" since it was just idle and i was bareley using it. The following day I connected to the wi-fi and I noticed it was draining the battery pretty quickly..almost 1 % every 7 mins even tho the screen was dimmed and most apps had been "optimised". I was also worried about the "cell standby" drain which was about 2% every 1.5hrs.
But things began to get out of hand when I began using the 3G connection to watch youtube videos, after just 8 minutes the phone became scorching hot to the point where I couldn't use it for a while. The battery percentage was falling ridiculously by around 1% every 3 to 4 mins, with the display on 40% brightness, apps optimised, background apps limited and all the other tweaks to save battery life being utilised. Location, BT, Wi-fi, NFC and auto-updates(GooglePlay) were all of and it was still getting hot.
Then I allowed it to drain completley to 0% but before that I disabled "fast charge" , it took 8 hrs from 2AM to around 10:14 AM to reach 100%...but this did not help the battery drainage as it was still the same as before.The cell standby reported 3% use in 12 hrs which is abnormal since other S7E( Nougat) users only got a hit 1% in 8HRS. I then came on XDA and saw that many other S7/Edge users that are running Oreo 8.0 were experiencing the same issue with no resolve... I have tried ALL of the following with not a single positive result:
1. Soft reset and wipe data cache partition. 》no difference made
2. Enabling "mid power save mode" to limit CPU speed and background apps . 》 still overheats and drains battery as before
3. Factory reset the phone (there was not much user data on it aside from 5 screenshots). 》did nothing to remedy the situation
4. Disabling any apps that might have been responsible for the overheating and battery drain uaing the Apps manager and the "app power monitor". 》no noticeable change
5. using the "Optimisine apps" option in the App manager
none of the above helped as the phone still gets very hot (when it is on 3G/4G data) and drains its battery much quicker than S7 Edges that were running Nougat a few years back.
AT THIS POINT I'M ALL OUT OF IDEAS AND YOU HELP WOULD BE GREATLEY APPRECIATED.

I recommend to update / flash latest firmware available.
Then install a battery stats app like Better battery stats (BBS), record an idle dump and post it in the BBS thread (https://forum.xda-developers.com/t/app-2-2-05-oct-v2-4-betterbatterystats.1179809/)
There are some experts analyzing your stats and giving advices how to optimize your system to gain better battery life.

Help needed : Too Much Battery Draining And Heating

So I recently bought a note 20 ultra exynos version , the battery is draining too quickly and the phone gets very warm even on normal tasks like browsing, youtube ( lets not even get too camera and gaming usage), there are no third party apps and no of apps itself is very low, also I use it on 30 % brightness most of the time.
What is the problem ? What should I do ?
It's always like that for the first week until it learns your usage patterns. I was about to return it when I first got it but I waited as everyone told me. Now I have one hour screen on time for every 10% of battery life so theoretically I can have almost 10 hours SOT. For standby drain It's like 0.5% per hour with wifi on.
Don't forget to disable the apps you don't need. Uninstalling bloatware with the ADB helps as well.
My N20U is exynos too
