Samsung S7 Exynos Overheating or bad battery? - Samsung Galaxy S7 Questions and Answers

Basically my galaxy for some reason when I play certain games or use the phone normally the upper center part of the phone heats up a bit and the battery just goes from 90% to 80% in like 10 or 15 mins. I've been thinking about changing the battery but I'm not sure if it's the battery or the phone that has overheating problems because I dropped it over the years and the phone deteriorated.

Hi! After the latest update I noticed that too, that something is wrong with how battery is going down so fast, but I have my phone for 1,5 year, so I will change for LineageOS 16.0 soon when I find some time.

There's one thing that makes me nervous, my phone heats up quite a bit and everytime it heats up the battery just goes that's why I'm confused.

I don't feel heating in mine, so I can't say much about it, maybe it is a clearly OS problem... I had that in my Ace 2 long time ago that after one update phone started to heat, so I downgraded it and everything went back to normal.

I installed lightrom custom ROM and its a bit better but still does the same, I'm praying it's just a bad battery

Batteries only last around 500 charging cycles after that they often cause issues, discharging faster which in turn makes it hot and batteries don't like heat, so essentially the batt is killing itself just as its designed to do.
It doesn't matter which firmware your running if the battery is going haywire and degrading, new batt or new phone is the only solution. AND of course no phone is built to last cause Sammy wants you to keep them in business.

That makes sense, thanks for helping me, actually my phone has 3 years, I didn't know it was so old because I bought it from a friend and I asked him a few days ago when he got the phone and he told me exactly when he bought it. I'm just concerned as why my phone heats up more than normal, I've seen people with s7 and they say when they play games the phone stays relatively cool but when I play games my phone goes to like 37C° and I know it might not be that hot but it's a bit unusual for me since I've never experienced a phone get so hot, I have a lot of old and new phones and no phone goes as hot as this one

Just had a thought about battery life

Ok. I was responding to a thread about my phone and no reboot's. I notice that some else posted they charge there phone with it off. When i first got my phone I charged it with it off the very first time. Has anyone else done this and not had problems or done this and it still bad battery life? I have had mine unplugged since about 5:30 am and at 7:08 at 38 percent in the staus menu.

ive done the full dead to full charge (plus one hour of charge time)
i get 14 hours of use usually and thats heavy use
people need to realize this is a DUAL core phone its gonna eat battery (especially with stock drivers/software)
dont like it go back to your razor......

Hey sorry for the confusion but it was not a helpful tip. I was just stating my specific way i charged my device, but your right it is a dual core phone. I hear the thunderbolt has pretty bad battery life LOL

Unfortunately, as far as I know dual core is supposed to mean better battery management.
So there's that.

I agree, especially after reading Chris Soyars' post about the battery driver. Not only does that mean our reading of the battery is directly affected, but it also leads us to believe that other drivers on the G2X could be poorly coded as well.
The battery life is ridiculous
Honestly I"m coming from a Sony Erisson w810i dumb phone due to lost of my Samsung Eternity 6 months ago. And I have to admit that it was worth waiting for this phone back when they announced at CTIA. I was so close to jumping onto the mt4g, but this unbelievable phone totally held me back. After waiting and suffering for 4 months from my dumb phone I finally got my hand not only on my first android phone, but also a dual core phone. Man this phone is blazing fast without any lag, going from apps to apps. Once I got it out of the box, I noticed the battery life was around 30%. After playing with it for about 30 minutes, it completely die out. I charged it while I was doing the factory reset. After the reset, I turned off my phone and left it charged 8 hrs while it's off with the battery charging screen. Waking up at 9:00am, it was 100% completely fully charged. Left the house to school and at 12:30p.m, it was down to 5%. It's been only 3 hours and 30 minutes! Before the battery started to drain I had wifi, syn emil, bluetooth and even brightness on low. Also, I had GSM/WCDMA on Auto, so that wasn't the cause either. My second attempt charging cycle to full battery, well see how it goes. If the battery doesn't last me over 6 hrs, I'm definitely going to return it for another new one. I'm having a bad impression on my first smartphone and I will do anything I can to get it the way it should be. It just unacceptable and ridiculous. Oh by the way, my phone is not yet rooted or done anything with it beside downloaded few apps and games. ^__^
i had this issue last night when I plugged in my phone it showed charging and 38%. woke up this morning 8 hours later and it still showed charging and 38%, I'm thinking what the f, this never happened with my nexus one. so I plugged the phone into another outlet and used a different charger and left it for an hour and it still showed the same thing. It wasn't until I restarted the phone that it showed 100%, but I find that odd. don't have the slightest clue why this happened.

I took my friend to a T-Mobile corporate store to show him the G2x I bought. I bought mine through TMO Loyalty so I had to wait for it to ship.
Anyhow, there was an LG rep there trying to showcase the G2x and G-Slate and I asked him how the battery life is for the G2x. He told me 6 days on standby and about 5-6 hours of continuous talk time.
I'll check to see if he's still there and take a PTO if I need to, to be there with him and call my office and let them put me on hold and see if the phone has enough juice to make it for 5 continuous hours.
Unfortunately tmo decided to add some apps that run by themselves....after I deleted them I havnt had any apps open without me opening them.....I get about 20 hours wth a lot of use. This is the best battery life I have gotten on any android phone

I don't see how to get 20 hours out of that battery! Are you on edge? any live wallpapers? Account syncing?

Battery life is plunging from 80% to zero

Hey all,
About three weeks ago I had a strange problem. I noticed that in two straight charge cycles, my battery life plummeted from about 80% to zero in just a few hours. I'm not sure what the issue was. I hadn't changed settings, installed new apps, etc. My first screenshot shows an example of what happened. 4G and data were off during the entire time.
Since then, things have been okay. I typically get 3 days standby with 4G on and light use, or 4 days with 4G off. That's mostly standby with maybe an hour or so of talking and minimal use.
After those strange battery plummets, I installed and used GSam Battery Monitor to get more details about what processes were running on my phone in case I noticed the sharp drop happening again. Everything had been fine for over two weeks, with me getting expected battery life before this issue and not experiencing any odd, sudden drops (maybe 5 or 6 charge cycles). This lends me to conclude that my battery's charge capacity is okay, and calibration also shouldn't be an issue.
However, the problem arose once again a couple days ago. Went from 75% to nothing in just a few hours. 4G was off during that time. The third and fourth screenshots show the same issue. Charged my phone, and this morning the same thing happened yet again. At about 90% the plummet began, and within an hour or so I was at 75%. At this point I took screenshots of Android's battery status, and I also did the same for GSam to show what apps and processes were running. The phone's temperature seemed fine.
The GSam screenshots taken when the phone was at 75% and dropping are in the next post, since I'm limited to four images in this one. I have no idea what's causing this massive, sudden battery drain. The only thing I can think of is that I've done Verizon's OTA updates, but otherwise pretty much all my settings, apps, and usage are the same. Plus, for two weeks I had normal battery behavior, so I'm completely baffled.
I also know that cell standby is incorrectly reported in the GS3 battery screen, and I'm getting a good signal where I live so that shouldn't be a problem. I forgot to get screen time for the first case (first two images), but it shouldn't be more than 10-15 min there since most of the charge was lost due to the freak plummet.
If anyone may have an idea of what's going on, or if there are some tools/tests I may use to figure this out, I'd really appreciate it. I turned off my phone after taking the screenshots at 75%, so if I need to turn it on and check something for you I can probably do that. Thanks a lot.
FYI, here are GSam screenshots from when the battery was in the process of plummeting this morning.
i think you built in battery status settings are off. i barely get 12 hrs with medium use, so what i think it happens is that the battery monitor is not showing the proper discharge, and then all of a sudden it catches up to the discharge rate.
are you on stock rom, rooted, unlocked bootloader?

I am stock rom. No rooting, no unlocking.
These plunges are definitely an anomaly. Truly, with me barely using the phone and turning off mobile data, I get a few days of standby. I've had the phone since July, and the aberration in battery behavior has been the steep plunges I've shown.
In between these instance of steep plunges, I've had normal use. I really don't think it's an issue of calibration. Please believe me when I say that my normal, light use during the past four months gets me anywhere from 3-5 days with me barely using the phone. When I say barely using it, I mean not even touching it for an entire day if nobody calls me. But now, a sudden plunge in battery life is happening at 80% with no apparent reason.
I think it might be some kind of software or hardware glitch, but it's impossible for this to be normal given the battery life I typically get. Just looking at that steep drop, it's crazy and just happens out of nowhere.
But please trust me when I say that these sudden plunges that have happened a total of 4 or 5 times, causing the battery to drain completely in a few hours when I'm not touching it, are quite a drastic aberration from the normal standby life I get. Something is definitely wrong here, I just don't know what.
And one more thing to add is that after this sudden plunge and rapid drain, charging the battery still takes the normal time it does when I'm not having this issue. That is, about 2.5-3 hours to reach a full charge (and I charge with the phone 'off'). The battery is being completely drained. But this happened twice, then didn't happen for maybe 5-6 charge cycles, then happened again twice.
Before the first instance, I remember an OTA Verizon update around 10/5. My phone was okay for 2-3 charge cycles after that. Then two rapid drains. Then 5-6 normal cycles. Then two more rapid drains. There was a second Verizon OTA update somewhere in there but I can't remember.
and you said it only started once you did the OTA update from verizon right? well you could either try to go back to the stock verizon rom pre-update and see what happens there, or contact verizon and let them know what happens with the new OTA update. they could replace your phone, or it could be a bug of the new OTA update. i am on stock rom and rooted and deleted the apk that kept on trying to push the update. just unlocked by bootloader and so far my battery life has improved compared to previous locked bootloader.
i would take it to a verizon store and show them. They might give you a new battery.
I may have to do that. I'm just not really sure what the issue is.
- The battery can still hold a full charge.
- Based on running services, nothing is causing high CPU usage.
- The sudden plummet almost seems kind of random.
- Since there have been normal charge cycles, it's not an issue of calibration.
I'm not sure if this is a hardware issue or software issue. I'm trying to wrap my brain around what could cause the battery to drain so suddenly and sharply. Could the charge somehow be "leaking"? But in that case I'd expect it to happen all the time. If there's an underlying software issue, is there any other tool I might be able to use to figure it out?

Not from what I can tell. Note that the first couple plummet drains were overnight.
But today I caught it before noon. The phone wasn't hot, and the GSam screenshots show no CPU stress.
Maybe you can do a factory reset and se if that helps. They will probably do one if you bring it to verizon anyways. It sure sound like a hardware problem. You'd think if the processors are working that hard that the phone would get hot, I know mine gets pretty hot sometimes under heavy use.
Sent from my SCH-I535 using xda app-developers app
Thing is, all indications show the CPU isn't working hard, and the phone wasn't hot.
I'm stumped.
This is a noobish question, but I presume the only way to go back to stock is to factory reset? One thing I might wait for is the Jelly Bean update, presuming this random drain holds off until then.
But yea, I dread going into VZW because they're just going to try to pass this off onto me doing something wrong, or me not knowing how to calibrate the battery, etc. The information I've provided in my OP and in the screenshots would fly over their heads. Maybe I can just do an online chat and tell VZ to send me another battery?
The only other thing I can think of is that sometime before these plummets happened, I went online to MyVerizon and turned off the Backup Assistant for movies/music/etc. so I wouldn't get all those notifications. I don't think this could be the issue, since the plummet happens when data is off. Plus, GSam would show that Backup Assistant is hogging the CPU or forcing a signal.
I doubt swapping batteries will fix it, though. I'm thinking my internal hardware might have a serious problem.

Before the update, was everything normal?
Is the update with the HE base/baseband?
It probably isn't a hardware problem, just a bad base.
I've noticed after updating my GS3 to the HE base and the battery life was just horrid.
It's said that the new HE baseband uses up more battery also

I turned on the phone and within 10 min or so the battery life went down by 2-3% without me doing anything. As a test I've put it into Airplane mode, and it's decreased by about 2% in 45 min.
Now I'm wondering if I have a faulty antenna or something.
Yup ive had it drain 90% overnight many times for no reason. Called verizon and my new battery should be here today.

HE is the baseband version and the build number. For example I have: Android Version: 4.0.4

which is the version before the update.
Like everybody else said, call Verizon or go to a store and let them know about the battery issues and they should send you a new one. Or even call Samsung and tell them you bought an S3 through Verizon and you are having battery hardware issues.

[Q] Battery Problens!!

Ive had my htc one x for maybe 5-6 months which is almost the longest ive ever been on one phone and i love(d) it, but its always been doing something very strange and aggravating that seems to be getting worse. Battery drain has always been a problem for me with this phone but ehh i can deal with it, but once my phone gets down to about 14% which is does often because of the draining it starts acting real funny with its power and sometimes goes from 14 down to 5 in an instant literally out of no where and as soon as i plug up itll go right back to 13, or itll shut down entirely at 14% but i can just cut it back on, or itll shut down in the middle of me doing something and i have to charge it for about 5-10 minutes before itll even come back on. The latter happened last night btw. No matter what combination of roms/kernels i try this always seems to be a problem. I really cant deal with this anymore and its to the point where i wanna throw my phone into a wall and just buy another one, which im seriously thinking about doing at this point. If such thing has happened to anyone before or you have insight on this can you please help before i just give up hope completely.
What you have described is normal for our device. Remember that the battery percentage is just an estimate of your actual charge. In addition, you find your phone shutting off around the lower percentages as a result of the device attempting to prevent damage to the battery. That is what the HOXl was designed to do.

Last night when it did it, as it has before, i was still on 21%.... thats not normal. And this isnt my first android nor first htc, never happened before. Even on my aunts old one s it didnt happen
Do you allow full charges after these "forced shutdowns" occur? This should cause your battery to recalibrate.

The battery behavior on this phone has been interesting. I have the battery last over two weeks on airplane mode and I've had the battery last just a couple of hours with just a stock setup. There are so many factors that play into this. I work in an area with very little to no signal reception and my battery life goes crazy and the phone can get really hot while I'm there so I've seen the best and worst.
What I do to counteract this bad behavior:
1. Charge prior to 40% (I've had the phone go from 40% to zero instantly before)
2. Consider your signal reception and either try out different radios or use airplane mode to reduce erratic battery drain
3. Install a 3rd party app like batterycalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en) and use that when things get hairy (I calibrate every two weeks or so and that does the trick for me.
My phone has been like this since I pulled it out of the box. With a little management, it is just fine. You have seen it before but I'll say it again, you have to get through a few charge cycles when flashing a new Rom to get back to normal.
Hope this helps. It works for me and I work in a cell phone reception hell.

When a new ROM or kernel is flashed you need to let battery settle for at least 48hrs before you get super worried about battery. If possible during that time let device fully discharge then charge up to 100. Please use a battery monitoring app and then see what's causing the issues. With proper config hoxl will get good battery life. There is always the chance its hardware issue but doubtful as battery prolly would of completely failed by now. Also check your screen brightness settings. Hope this helps

The battery behaviour you described is completely normal if you understand how a battery of this type works, and if you understand how the software (especially the display of battery percentage) works in conjunction with it.

So youre telling me having the phone get to 22% and instantly drop to zero and power down is normal? Makes no sense at all. Also i cant get it to charge too 100% for anything. So if theres no fix to this, anybody want a one x with a troublesome battery?
What I'm saying is the battery percentage displayed by the software is never exact, it's only an estimate based on the voltage level of your battery. Your battery sounds like its long term life (capacity) has been decreased over time and possibly bad treatment (allowing the device to discharge too much too many times).

Depends on what you define as "normal". Such behavior is certainly not unheard of (although you particular collection of symptoms may point to a more serious issue, which I'll get to later). Couple things you have to remember: the battery meter is far from accurate. Being off by 10% or more is not unusual (completely normal). So jumping from 5 to 13% as you mentioned is not out of the question. The battery voltage is not actually jumping around, just the % battery number that the phone is assigning to various voltage readings. Reading errors happen, and if a jump is noticed, its just the meter correcting itself.
Which brings us to the other point that should be kept in mind: the battery % is not a "real" measurement. Its just a number assigned to various voltages to give the average person a sense of how much battery is left. Its a completely fabricated and artificial measure that just gives some relative sense of when a user should charge their battery. Phone makers just decided to use a system that average people would understand, like the fuel gauge on a car. Zero doesn't really mean zero (or anywhere close), but reporting in voltages would make no sense for most folks. Also, as we all well know, just because (for example) it took you 12 hours to drain the phone to 50%, does not necessarily mean the phone will last another 12 hours to drain the remaining 50%. It all depends on what you are doing with the phone during that time. Which leaves the question: What does the % battery really mean? Really, not a heck of a lot.
On the other hand, the battery failing to charge to 100% is troublesome, as is the apparent frequency of the meter drops and the fact that the issue remains after various ROM flashes. Leads me to believe there may be some hardware issue going on.
The short answer: IMO while some of the individual symptoms are not unusual, the seeming frequency (you haven't exactly quantified this, but it seems relative frequent just based on your descriptions) may suggest a larger issue, but its not certain.
Thanks it explained a lot but it happened again today, went to the store with ~36% on the meter and walked out, haven't touched it at all, phone was completely dead. Tried to charge and it went to 6% and stopped charging, all signs showed it was charging but it was stuck on 6. Then it started climbing again and reached about 16% and actually started losing charge while on the charger. Switched over to my portable battery charger i just got and it held the charge at about 5% for ~30 minutes, which is what it was when i plugged it in and started to charge, then it stopped againand during the whole process the phone was getting very hot. Yea im getting a new phone :/

New phone battery life

Hi!
I am new to the nexus 5 community and I just got my nexus 5 about 2 days ago
After fully charging it I started using it , I have heard that nexus 5 has battery issues and that's why I only want you people to help me tell how the battery life of my phone is for a brand new device by seeing the screenshots of my usage.
Here are the screenshots:
Looks normal to me. What's ingress? A game?

Not bad. I would disable Wi-Fi always scanning available (even if Wi-Fi is off), location to start. That's not bad though and is about what I get, but you might be able to get better SOT.
the nexus 5 does not have battery issues, at all. it stupid people that themselves have issues, not the phone.
Seems normal to me ,I bought mine month ago
There are no issues with battery on nexus 5. I charge mine usually once in 3 days, my record without charge is about a week.
It really depends on how you use it. Under constant 100% load I think battery can be depleted under 5 hours, as in every other device.
i can use my phone very heavily, and deplete my battery in 6-8 hours. but ill still get 5+ hours screen on time.

Have you tried running the phone down till it switches off? I know it's not good practice to do that often but I like to do it with a new phone relatively early as it makes sure it's calibrated - sometimes phones can either switch off at 5% or, conversely, run on 1% for hours...

You don't ever need to do that as it calibrates every time you charge the phone. Also he just got the phone and isn't having any battery issues.

He means to break in a LIon battery the first three times you kill the battery and then don't take it below 20% after that.

That's not helpful and does more harm than good. Li-Po never needs to be user calibrated in any way.
Thanks!
Thanks a lot guys for taking your time and helping me , nexus 5 is truly an amazing phone.
@Ben36 yes , ingress is a game and its a location based so it keeps running in the background and uses location services.
Guys , I have some questions relating to the vibration motor , is it fine if I ask here or am I supposed to make a new thread?
Thaks a lot once again

I was just about to start a thread about something then I read this. So here's the deal. I agree that it's almost always user error and/or over expectation when it comes to battery. Stupid people are here to stay. I'm neither stupid nor expecting too much from my battery.
I've always been intrigued by how some experienced users get great battery and some get not so great. Has to be user error I always thought. I thought this because I was one of the experienced users getting great battery life. I mean GREAT. Way over 7 SOT all the time.
So a few weeks ago my first phone had an audio port issue that I had RMA'd. I received the new phone and set it up. It had crap battery. I'm talking less then 2 hours SOT. Same ROM, same kernel, same apps, same coverage for mobile and data, same usage. I set about looking for wakelocks and they all where the same as the first phone. Nothing was wrong on my end. I spent over a week troubleshooting. CPU frequencies and time in state where normal. Temps where normal. CPU benching was the same. Awake vs screen on was almost identical. The phone is sleeping like a baby when not in use.
So, using Occam"s razor, it would lead me to believe that not all batteries in the N5 are created equal. After getting off the phone with a google support supervisor a few hours ago he agreed. Another RMA process has been set up and I was promised this phone would make it's way back to LG so they can actually analyze the battery.
Like I said, I used to think the same way you do. Now I'm not so sure.

oh, no, I 100% agree with you. just like our devices, that all aren't equal, that are all assembled in differing places, that all have smaller parts that are made in more different factories.. the batteries themselves will differ as well. it'll even probably fall onto a bell curve, where most are near the center, and less with better or worse. but 100% they vary.

Well I feel that there are always some exceptions , some phones may have a manufacturing defect and maybe the phone you are talking about did have one , but these manufacturing defects are mostly really rare.
You should be good to go...just keep an eye on it! Happy Flashing

I was just explaining what he said. The rumor is (supposedly backed up) that you kill the battery 3 times in a row but never take it close to dying after that and you get the best battery life possible because the battery works best if you only charge it between 20 and 80%. I think there may be something to it because new phones only last like half a day on the first charge but after a week last a day or longer for me. I won't derail this thread though as that's a debate that always loves to go on and I've never found hard proof either way but people who just write websites who supposedly sound smart and can word it quite eloquently.
That being said, I didn't necessarily agree with it, but I was clarifying what was said.

Thanks for clarifying. Keeping the battery between 20% and 80% is said to help with battery degradation, which after a year or two might affect how much one could get out of a full charge. Most won't find it practical to limit them self to only 60% of their total available battery pool though.
Even hitting 0% isn't as big of a problem as some may think as there is a reserve charge for protection. For instance, mine has full died on me twice due to a power outage (I even attempted a boot up) and I always full charge with no noticeable degradation after 8 months.

Battery life greatly getting worse

Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.
Thanks!

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine
