Rubbish battery life? - Samsung Galaxy S7 Questions and Answers

I got an S7 G930F yesterday, first full charge last night, I haven't it even properly set up yet, haven't got most of my apps installed yet. I took it of the charger this morning at 8am its now at 50% at 2pm, 45 mins screen on time with the biggest battery drain being android system 20%.
I have hardly used the phone today as I'm off work, at this rate it'll be dead long before bedtime with me doing nothing.
Any ideas?

Hard to expect getting the best of it at first. It took me a good week to figure out how to optimized battery without having to use it like a 2G phone. I suggest you do factory reset. Observe how it goes that way. For the first time, a handful of things run in the background; syncing, location, whatsoever so I bet it'll take a while to really adapt and I can assure you based on experience, it's like that as it was like for me.

Always takes a few full charge cycles to get the best out of a new battery I find, fully charge and fully discharge 4-5 times, calibrates the phone too to know what 0% and 100% are iirc
But you're always going to see high battery usage setting up a new phone, installing apps, screen on constantly, playing about with it more than you will once you've had it a while

The are wide reports today of crazy bad battery life. Some people are tying it the latest Oculus update.

I'd like to believe that but I didn't have this issue on my Nexus 5X with a smaller battery or Huawei P9 Lite, in fact the P9 Lite also has a 3000mAh battery and I could make it last 2 full days, this won't last 1.

Getting the phone yesterday, you've hardly given it a chance, with heavy usage I get just over a day with mine, with medium, 2 days
Same phone, same OS, same battery
See how you get on in a week or two, or return it and get the Edge, 3600mAh
Check the package disabler pro threads, disable the battery draining bloatware (no root needed)

Yep thats the usage I got with my P9 Lite with the same size battery. I was sitting this morning look at the phones always on display. 30mins of the charger it was at 94% and that's with me not even touching it.

It's crap for the first few days
Whenever I first got my phone or when I factory reset or when I install new rom, the battery life is usually crap. But after a few days when battery optimization kicks in (power saving on apps not used in past few days) battery gets tremendously better.

Posting back to confirm that Oculus update shat on a lot of phones.
Oculus home process kept trying to install and uninstall. This demolished battery life, increased heat, etc.
Once I uninstalled Oculus, all problems went away. I will reinstall after fix.

This may be caused by either the oculus app or good lock app they have been reports on the Internet about these two particular apps
Also when setting the phone for the first time it will drain battery in the first few days

Confirmed about Oculus draining battery

Definitely was, my phone overheated and shut down over night when the update came through. I literally couldn't charge it it with fast charger. it would just sit at the same % it was burning through the battery so quickly. uninstalled sammy vr and oculus apps everything fine now.

I don't have anything oculus related installed. The is day 2, second full charge last night. Of the charger now 1 hour, its got flight mode on with wifi calling enabled. I am currently at 90% with 1 min screen on time. Android services again the biggest hog but it contains IPSec services which does the Wifi Calling part.

I was about to remove Occulus when I received an occulus update, about one hour ago, and it seems that the problem is fixed. The battery looks ok, and the phone is not hot any more. I'm waiting a little bit more to be sure...

Right guys I have found the culprit of my drain issue. Wifi calling. I happened to turn it off and I have gone from 10% drain in an hour to 1%

That's more like it, never used WiFi calling so wouldn't know if it causes drain
EDIT - Not available with my model / carrier

There's a debloat script back in the Development Section which will remove all those trash that came with the phone, as for battery optimaztion This Ultimate Battery Guide is one of the best here in XDA and is a must see for anyone with an android phone basically
Goodluck

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.
At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.
I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..
I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.
I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.
I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.
mine's was better actually. but i didnt stayon it for long
My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.
Not here, seems the same to me
Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.
Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.
I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.
I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.
It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

Very curious quirk On Android Open Kang Project ROM... Near Unlimited Battery!!!!

hi all...
soo after my comments over a week ago on the aokp website for this build, i decided afterall to take the plunge and update. i was on b26, so subsequently had to flash b27 and then this. everything has gone absolutely swimmingly with no issues at all so far....
HOWEVER>>>>>
I am faced with a very puzzling quirk. its by nooooo means a problem at all, infact it quite the opposite!!! let me explain.
i've started charging my phone in the evening these days for some stupid reason and then, when charged taking it off and going to bed. After getting this milestone on, my battery has been killed over night, draining to around 15%. Normally, it would drain to around 70% and be flat by the end of the day ready for charging again.
This continued for a few days when i decided to root out the cause of the massive overnite idle drain. I installed a fantastic free app called Badass Battery Monitor (which i highly recommend btw!), and over a period of a couple of days the offending app was weeded out. It was Nova Launcher. This had never happened to me before and couldn't understand it. So, as part of my diagnostics, I decided to confirm the findings by removing it and just using stock.
Over a couple of days monitoring, with exactly the same charging method, my battery levels returned to normal drainage with around 75% battery left by the morning. Fantastic. I had found the problem fixed it and got back to normal. Soooo where is the quirk i here you say!!!? lol Well......
On average, from everything i've read in forums, battery drain overnight while phone in standby is around 20/30%, so mine WAS right up there with the majority of you.
Last night, i decided to charge to full and then wipe battery stats. Which i did. Now, bare in mind here that I ONLY have the standard battery that is supplied with the Galaxy Nexus. I got up this morning, and to my utter amazement, my battery had only drained 2%
Now been incredibly realisting here based on average overnight drains, i was 100% sure that this was deffo an error. I have done everything from restarting the phone, taking the battery out, but still the level in my battery was saying the same.
As I sit here writing this, I have been streaming a radio station via wifi on the phone for the last 2 hrs, and atm my battery is telling me that it is STILL 85% full.
I am DEFFO not complaining, but i'm sure now, you can see why the hell i am so puzzled! HOW THE HELL IS THIS HAPPENING, because i can genuinely find no explanation at all for it
as a follow up, it is now more or less 5 hrs since my orginal post, and my battery is reporting that it is 75% full
Jeesh, 20 to 30 idle drain overnight? My phone drains about 3 to 5 overnight which is typically 8 hours of sleep.

Interesting quirk. Are you a heavy or a light user? It'd be nice to see how it drains after a full drain and recharge.

well, to see if what was been reported was correct, i've been an absolute heavy user today. i have wifi on, ive streamed radio via internet for around 3 hrs, ive been playing all sorts of games and watched a few youtube vids. and my battery is atm reporting 74% life left
so here i am, STILL very very puzzled..
my battery life is just going and going with no signs of running flat... have a look at these screenshots and give me an explanation as to why i suddenly have a super battery!
MAYBE you really have a super battery or your mobile is glitched and shows the battery like that due to laG?
I'm on miui and I lose 0% overnight. It just depends on the ROM, but 20-30% is ridiculous!

Your states do not seem super impressive. On most phones the screen is the biggest drain. You show 49% battery with a screen on of only 1 hour. After 33 hours you've only used your phone for 1 hour screen on. Thats VERY little.
I usually get 2.5-3 hours of screen on time for my galaxy nexus.

Thanks for the app recommendation! Been looking for something like it all day.
This will depend on ROM/Radio/Kernel user installed programs/sync etc but 2-6% is normal drain over night anyone with 20% needs to seriously look @ battery stats and work out what's causing wake locks.
Also not forgetting most phones need to bed in after a flash which can take 2-3 days before we see real battery info.

Bad Battery life or Bad Battery on Nexus 5 with 5.1

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.
Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).
As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause
bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.
I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.

SERIOUS Battery Drain

i know there are a lot of other threads out there, but I haven't found one that talked about the problem deeper and has a fix. anyways, I'm experiencing a serious battery drain where I charge my phone up to 100, unplug it in the morning, go to school and leave it in my pocket for 2 hours, and it ends up being 70-80% and the screen on time isn't even on the battery stats because I've barely used my phone to have it show up. As im typing this on my phone, ive even lost 2%. Is anyone experiencing something similar and is there a fix for this? At 33% now, according to the battery usage, cell standby is at the top of the list with 10% and screen on time is 25 minutes . Thanks so much
Please post some screenshots of battery stats and someone may be able to help

My phone is the same way. Even with the latest update that made cell standby way better where it sits at 1-3% my phone drains like crazy. It's been off the charger for 3 hours and 1 hour of screen on time and it's at 57%. They need a bigger battery in the s7.
Check to see if you have a VPN app installed, Firefox, Candy Crush (or other King app), or a weather app. Many use mdnsd that eats power. King apps send data all the time. And there may be some adware that you have that is eating power. Hope this helps...

Battery Drain
I have had the same problem. With the earlier update I had the issue with (what I consider) excessive drain caused by cell phone standby. With the latest update cell phone standby has taken a back seat to Android System. Here is a screenshot from today. As you can see Android System has more than twice the percentage of anything else. I reset the phone a couple of days ago but that had absolutely no effect. Went to a local Verizon store to complain which naturally went nowhere.

I did a factory reset in recovery wiped cache twice and rebooted I have had much better battery. 20-30% higher when I leave work. I also kept WiFi calling turned off not sure if that was the drainer.

Weird problem with battery on unrooted phone

I bought my phone new when the Galaxy S6 first came out and have not rooted it.
For while now my battery life has been bad but consistent, or I would say acceptable given what is running in the background. With normal usage, including connecting to a bluetooth watch, LTE, and location services on, my phone battery would drop from around 100% starting at 7am to around 70% by noon. On weekends when I'm just at home and have it on Wifi instead and no bluetooth, it takes until around 6pm to drain to 70%. These numbers have been consistent, give or take 5% for over a year.
The problem started recently when I received an OS update. I can't remember if I was already on Android 7.0 before this update and it was just a minor update for something else, or if this updated me to 7.0 from 6.x
The first week after the update the battery was great. With no change in the way I use my phone I was able to go the entire day without recharging. By noon I was still at 85-90% and by around 7pm it showed 60-70%. So I was able to go the entire day without recharging for almost 2 weeks after the update.
The problem started 3 days ago when suddenly the battery is draining like crazy, and it seems like there's something weird with the battery indicator and the way it's charging. Again, nothing has changed in the way I use my phone.
Now, when I use it, the battery will go down by 1% every minute. And even when I don't use it, it will be down to 70% by 8am and 20% by noon. The stranger thing is when I try to charge it.
Before, with normal use, it will take around 1 hour to charge my every night. Also, the indicator showing how much time is remaining is pretty accurate as well. Now, when I charge it, it seems to take a lot longer. The time indicator will sometimes fluctuate. It may show a realistic time like 45mins remaining, then change to 10mins, then back to 45mins. Also, the times seem to be incorrect. For example, before if I'm at 85% it might take another 15-20mins to reach 100%. Now, it will be at 85%, say it will take 40mins, but after 40mins it's still only showing 90%.
I tried restarting my phone normally, and resetting it by pressing the the vol down and power buttons. I also tried other power saving methods like forcing apps to sleep when I'm not using them. But for some reason, the battery is still draining like crazy.
At this point, given what is going on when I charge the battery, I'm wondering if the real problem is the OS update screwed up the way the phone is reading the battery's power and not that the battery is actually being drained. Maybe the battery in fact is still at 70% by noon even though it says 20%.
Sorry for the long post, I just wanted to be as detailed as possible given that this seems to be different from some of the other battery related problems I've read about on the forums.
Any help or insight will be appreciated.
