Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?
battery life
I've had my phone off the charger for less than one hour and I'm already down to 90%. There's definitely something wrong because stock lollipop unroot was giving me much better battery life and performance.
Mine lasts about a day and tbh for a device with the specs of a low end PC with a HD display and constant internet connection thats about what id expect

When your battery lasts less than HALF the time of what it used to all because of one update, something is seriously wrong.

well mine lasts a day now and it did then. so either you need to factory wipe, or you need to look at apps you've installed thats not quite optimised for lollipop
Yup, factory reset solves battery drain after LP update, I was up to day 3 without charging this morning with still 18% battery left, but had to charge up as I was going out, reckon it would have lasted the rest of the day though

Got a reply off the Samsung Twitter team to do this, so now going to give it a go. Hopefully it'll sort it because the drain is driving me nuts
Without losing root?

Factory reset will lose root more than likely, almost certainly
It happened with me but after 2 days everything settled and battery lasts at least 12 hours but still less than kitkat.
I installed the update to lollipop..... After that indeed a horrible battery life. So I installed lollipop again using kies software......
Had same experience wipe and reload greatly helped. Supposed to be addressed in 5.1.
To add yet another subjective and anecdotal experience with the new S5 Lollipop update (on Verizon, in my case), I was seeing constant Wi-Fi disconnects (~5/minute) AND battery-life that went from ~15 hours to < 5 hours, until I turned off the "Smart Network Switch". Seems all the network switching was killing the battery as well. Did a FDR and it made no difference. As long as that feature is turned on, my Wi-Fi drops constantly and the phone heats up and the battery dies in a few hours, even without use.
Would be nice to know what I'm missing now that my phone is, apparently, using the Dumb Network Switch instead.

All you're missing now the phone is using the dumb network switch, is bad battery life, constant wifi disconnects, and headaches
I turned it off a while ago, and so have many more people I read about each day - it's supposed to keep you connected to the strongest signal, but in reality, it does the opposite, plus most people only have 1 wifi connection, so it's not necessary to smart switch - and even without it enabled, it will still connect to Data when it goes out of range of WiFi, so that switch is completely pointless to start with

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?
Oh well.

You could set up your two APs with the same SSID / Encryption key and have the phone switch seamlessly between them without smart network switch enabled

But yea, it seems that there are quite a few overlooked bugs with lollipop, 5.0.2 and 5.1 apparently address a lot of them, but when we get that update is anyones guess

Wrong section, all questions go in Q&A. Not general.
please note that there are some apps are working without permission like google music i think ,
I recommend you to stay in KitKat until Samsung Lollipop 5.1 firmware arrives. At the moment I'm using XtreStoLite ROM with Toiiki kernel and I'm getting am awesome battery life, about 8 hours of screen on, cheers.
My S5 is G900H and I have the same problem. I did not like lollypop
Hello everyone!
So I have been having these battery issues since April security patch. the phone gets really warm to the touch even by doing the simplest of things like browsing and watching youtube. Android OS keeps the phone awake 80% of the time and I am only getting 2-3 hours of use throughout the day. Restored the phone to factory settings(fresh start, nothing restored) three days ago and still the same issue. Android OS drains the battery life even though I made sure that only google apps are installed on the phone.
But today things got even weirder. I disabled Google Now and location services as a test and the battery drain and heat issues were gone temporarily. I was getting a great battery performance from morning to afternoon. I check my battery stats and I notice that Google services mysteriously drained 17% of my battery life and that it's been running for 21 days straight? That's impossible since I just did a fresh reset to the phone three days ago. I rebooted the phone and that "Google services" drain changed to WiFi instead?! That's crazy!
I contacted Google store support team and they have been really helpful so far. They offered to replace the phone with a refurbished unit, but I don't think I am ready to give up on this phone just yet.
Thank you!

I hate to recommend this, but sometimes things go out of wack after a SW update, so a hard reset would probably be needed. I would try that (just start from zero) before jumping into a refurbished phone that might have some other kind of issues. Have you tried a hard reset yet? I see that you did a fresh reset. Did you go through the recovery though? Not just the regular UI. I think it's better to clear cache, and every thing through the recovery (custom or stock).

I did it through recovery. I have cleared the cache and rebooted the phone several times the past few days. Nothing seems to help at all.

Wow. Maybe a custom ROM might help? Have you tried that? That's the last thing I would do. Good luck!
Not recommended but I just flashed January vendor and ROM and that has helped my battery life. I. Believe it is the security updates that kill our battery.

Is it a widespread issue? Like I said in my post, I saw the decline ever since I got the April security update. The May patch actually managed to make things worse. There seems to be something hidden in the OS that it's draining the battery and causing the awake issues. I haven't tried rooting the device because I lack the experience to do so. I will probably look into it on these forums, but at this point I have tried everything.
Disabling Google now helped a lot and it exposed some sort of a glitch with the stock battery monitoring app. I am not sure if it's hardware or software, but it's certainly not normal. I am tempted to just replace it, but I am afraid that this issue will just plague the new one from Google. I am really disappointed How Google handles updates on this device. I always thought that stock android is most stable version of android, but the software on my old Xperia Z is actually more stable than this. It never had battery drain issues and standby battery life was always great. The battery life on Nexus 6P is actually worse than the Xperia Z even though that phone is 3 years old.

I've seen a lot of posts over the months with people having the same problem we are. I came from a mid range LG stylo with a snapdragon 610. I would have 8 hours screen on time daily. Its sad that goggle cant get the same out of their own hardware. Also I have seen that the Note 5 and S7 Edge both get better battery life as opposed to our stock phones. For as much as people praise stock and look down on Touchwiz, they are doing something right over there.
But it doesn't affect everyone and that what puzzles me. Only certain phones are hit by these issues, while other people are getting excellent battery life. I have seen plenty of people post screenshots of 6 hours+ of on screen time. I am lucky to get 3 hours. I think Google should really invest in creating a better power management system into Android. Companies like Sony and Samsung built their own and the battery life on their devices always perform predictably relative to what I am seeing on this phone. I have never witnessed The doze feature kick in since I have bought this phone. Sony had stamina mode since 2013 and it actually worked.

Most of those people posting those outrageous number root and do kernel tweaks. I've gotten at most 6 hours SOT on stock without root. You are right our phones do all react differently to certain circumstances. I don't know if it's feasible to you ,but you should try rooting and trying out a few Roms some help others don't. If you aren't into Roms and decide to root try earlier vendors and stock roms and see it those work. I'm not an expert by any means just my suggestions.

Well, the fact that you are having great battery life proves my point. It's either that the quality control of the batteries used on these phones are terrible, or that the software or kernel are corrupted from factory causing these issues. There is no way to fix them by hard reseting the phone so far. I am going to try to flash a stock rom on this device and see what happens. Thanks by the way.
1) Are you rooted? If not, at least do that and install BBS in order to track down what's eating your battery.
2) Probably we'll run into a common problem / bug the last two months.
After unplugging the phone, it seems that the wakelock *backup* runs constantly, does not let phone get into sleep, and runs in the background while using your phone causin battery to drain faster.
3) About battery life. Comparing battery results between two users it has no point, unless you really now his usage pattern. Not only the setup, but which apps of them used most etc.
For example Facebook app is real battery eater. I've seen an hour more SOT without this app.
I can give several examples like this.

Hello,
I dont really found centralized information about Oreo and feedbacks regarding battery life.
So please, people from Korea and North America, can you provide some feedback about Oreo update, especially about the battery life ?
I heard some negative opinion from this video : https://www.youtube.com/watch?v=m5hH0TQY6Jg
Before he was at 5-6h SoT, after update 3-4h
Thanks !
It was entirely predictable and expected that there would be no improvement in battery life or performance with Oreo despite all the anticipation.
I have literally NEVER seen a major operating system upgrade actually speed up performance of identical apps on the same device. Sometimes there might be a non-significant decline, but never an improvement.
Each Android upgrade promises some new trick to improve battery life like wakelocks etc, but it's only theoretical and perhaps applies only to brand new hardware.
Otherwise the progressive process of bloating in updated apps and system software use more power and more resources which more than compensate for the supposed improvements in efficiency
I think the few reports that have mentioned improvement are just the random variation that people get, even with Nougat, or even day to day on the same device.
Sometimes I get 1% standby drain per hour and sometimes 3% with no change in use or settings. I have found no consistent way to control this, including trying all of the tips mentioned (except for wiping my phone and starting from scratch).
So far the video reviews that I have seen of Oreo on the G6 are pointedly unexciting and confirm my predictions. As far as I am concerned the only reason to update is for the security patches. I am hesitant to update given that going backwards is difficult on a unrooted device.

maybe some little improvements are made, sure, nothing big to say its a major update, NO!
is almost only a Android version bump and a security patch. PERIOD...
The features this new version introduced is low and people who update the phone dont will see a big change, i already see some videos of update in youtube and didnt see too much difference.
Of course is a good thing LG doing it but isnt night and day,is more like some hours of difference.
Lets see with time to time the Doze mode and power savings features step in and see some change in battery life, i trust LG make something to improve it, again nothing special but for me that already make a difference.

2 remarks :
From my experience, I never saw an android update improve battery life too. But that was a long time ago, with "cheap" phones (expect nexus 4, so disappointed). But recently, a friend bought a Nokia 8, and after the Oreo update, the battery has become so amazing, I was really really suprised and so jealous! So now I still have a little hope ...
However concerning standby drain, for me it's pretty ok. In airplane mode lost 0 or 1% for all night, and with data or wifi, it stays "normal".
You guys have something else going on.like the first post said it depends on day to day and other factors like many apps running in back ground.My phone and battery have 0 issues.on full charge it stays at 100 for about 10min on heavy internet use and then drops about 2percent per hour.I only charge my phone every 3 days.I also found phone much faster after oreo and less studder.I suppose because part of the update is to have less apps running in background.I wouldnt really listen to some users because the change log for oreo is huge.Soooooo many changes under the hood.people should read the change log before giving false facts(and they are false)Always gonna have some dude complaing about something

Did you make some improvements like disabling logs and reducing resolution ? Any reset after oreo ?
I disabled event logs yes.kept screen on large size and no resolution change.Yes I did a factory reset immediately after.I think alot of people are having issues with battery because they dont calibrate it first when new out of the box.As a rule of thumb no matter what electronics i buy i always charge to 100 percent and literally let it drain to 0 percent then full chage again.Do this step twice in a row and i can pretty much guarantee you wont have issues with battery that are out of the ordinary.LOVE MY G6

There are people that mainly use the phone under a wifi connection, and others that use it under a mobile network, this is just an example to give you an idea of why there is much difference between users
Y kllua but people are complaining regardless of wifi or mobile network. My package includes 6gb of network per month every month i spend 4gb etc...
And lots of people i see have bluetooth, nfc ( if they even thats in or what it even is. ) and then comes some1 like you and says ooo wifi on. What im gonna use at home ? Data ? To consump battery and empty my month data, and what im gonna use on streets, work, free time outside house etc. Mobile fking data. You think wifi is all around us

Well, my G6's battery sucks because at work the phone switches every couple of minutes to all the networks, and so I'm not able to reach home after 9-10 hours with 1-2 of SOT without charging a 20-30% during lunch, besides in weekends where I'm almost everyday under a wifi connection I easily reach 4-5 hours of SOT with gaming in a full day usage.
Also yes, there are many other parameters, like BT, NFC, GPS, Apps ecc...
So finally got Oreo thanks to LG Brigde.
The battery stock app seems really... broken ? Please see screenshots.
The message says : "2 days ago , 1h27min left the conversation."
PS : I made a factory reset after the oreo update.
Mine has actually improved! I'm getting like 30 minutes more (the improvement came after I drained the battery almost completely and charged it back like 3 times and after a factory reset). Not much but I can't complain. I'm actually happy for the improvements in fast charge speed, it's even faster now.
Third day with Oreo now.
Battery life is great, at least as good as before. I have 3.5h of screen on time right now and I'm at 43% battery at the end of a full work day with traveling etc.
And that's with Nova Launcher, Gesture Control [root], Always on Display and Pixel live wallpaper enabled.
Very happy with the G6 at the moment. Of course battery life always depends on your personal use and different phones provide better battery life for different people... G6 seems to work well for me and definitely better than the Huawei P9 I had before.
For people with battery life issues I suggest this: Battery life guide (I keep resolution at max because it messes with AOD and camera)
and also if you don't use google voice assistant try disabling the google app and use the chrome search widget instead. And keep location services on battery saving mode if you don't need GPS all the time.

can i ask where you got the browser? ive been trying to find it in play store with no success, thanks
After the Oreo update, my s7 active has really sucked. A lot. It overheats, battery drain is through the roof, it lags constantly, the camera takes a solid 20 seconds to respond at times, and it just generally sucks. The problems sometimes seem to be heat related, as it slows down even more when on charge. I'd seen on another forum that flashing the older CP file would fix the heat issue. Anyone have any luck with this? I haven't done much android modding since the days of ICS/JB/KK, before knox and all of that. Would doing this brick me or trip knox? Any alternate suggestions besides ditching the awful carrier AT&T is in favor of a lesser evil that allows me to use a third party phone with WiFi calling or VoLTE support? That's all that's keeping me with ATT branded phones now, as where I live has little 3g reception for an urban area, so having to drop down on calls without VoLTE is a no-go for me.
Thanks guys!
Have you tried doing a hard reset on the phone first? It sounds like you updated to Oreo with all of your junk on it. No wonder it caused so many problems!
There isn't a way to downgrade from Oreo.
No way to downgrade from nougat but as I understand it, isn't it just the boot loader that can't be rolled back?
I'm not sure if what you're proposing is actually compatible but you could always check.
Best way to keep all your bits and pieces in my opinion is Samsung backup.
Just did it myself and I am getting better battery and cell signal than I ever have! On a two+ year old phone!!
I just got 4 God damn days of light use between charges!

Sorry, been away for a few days. I have done a reset and it works alright for a day or two then back to total suckage. I managed to drop 55% battery in a matter of two hours this afternoon with moderate use. Bright side, it was cold outside, so I got a nice hand warmer. What did you try? Flashing the older CP/CSC?
I was under the impression that the older OS wouldn't work with newer bootloader.

Before doing anything drastic like attempting to flash CSC from a previous version, have you tried clean flashing the following rom in latest modified Odin including all relevant wipes?
G891AUCS4CRJ1_CL13639069_QB20030093_REV02_user_low_ship_MULTI_CERT_meta
My original comments were more towards the fact that radio behaviour on this rom has been totally different for me than every other version I've had on the device, as a result I seem to be getting much better battery life. I'm not sure what CSC it comes with, but it is certainly acting in a different fashion to all previous versions: Lots more time with 4G icon, less with LTE. Far more readily jumping over to 3G when the signal is stronger etc.
After charging my device is still getting hot, but not during general use. I think my battery is just dying a slow death - it only has 3000mah capacity now. A real shame that it isn't replaceable without defeating the waterproofing.
If the Sonim XP8 were a little bit better specced I would buy one in a heartbeat.
Nice, I'll give that one a shot. I was going to flash a clean install of CRJ1 tomorrow after it downloaded. Don't have very fast internet here. I appreciate the input!!!
If it weren't for AT&T restricting VoLTE to their branded phones, I'd jump ship to oneplus or anything in the pixel lineup. Or the LG g7. Or literally any third party phone that wouldn't force botched updates and bloatware down my throat constantly and re-enable crap I've disabled with every update. But where I work has great LTE signal, very very little 3g/HSPA+, so not having VoLTE isn't an option. Same for wifi calling where my parents live, poor signal so no use having the phone when I visit if I can't use wifi for calls/texts.
Currently using my old g5. Whew. I forgot that this thing would fry eggs with light use. But at least the battery is replaceable. Tried replacing my aging S7 active battery on my first one. Four days later the bottom half of the screen died. Oops.
HELP!!!
I picked up an H918 for my wife to use on T-mobile USA. Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

When I bought my wife's phone it had a battery drain/overheat and wakelock issue as well. I fixed it and haven't had an issue since. Here's what I did to fix it:

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
