Battery life greatly getting worse - Samsung Galaxy S7 Questions and Answers

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.

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

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?
Does the phone get hot?

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.

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

Sorry, I don't know what you mean by "HE" base/baseband.
But yea, this problem didn't come up until after an OTA update.
Check your baseband version under Settings -> About and paste it here

It's I535VRLHE
Kernel version: 3.0.8-1092717
Build number IMM76D.I535VRALHE
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.
1+ day on battery and only 11 minutes of screen time?!?

HE is the baseband version and the build number. For example I have: Android Version: 4.0.4
Baseband: I535VRLG7
Build: IM76D.I535VRALG7
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.

Well, no calls made or received during that time. No data being used.

Note 3 battery drain...

Ok so i've seen a few threads between here and other websites regarding the Note 3s battery issues but felt the need to make my own as I still haven't found any kind of solution.
I purchased my Note 3 N9005 (I live in the UK) around a month ago and ever since my battery has been terrible ever since. I am basing this on the fact that I have owned a Note 3 twice previously (I managed to get one just after they came out for a reasonable price second hand and also owned one around 6 months ago for a while) and battery life on those two devices were fantastic.
Around a week and a half ago I decided to root and try a couple of roms to see if it would make any difference after making sure it wasn't my SD card causing the problem and couldn't really try anything else. After going from the CMRemix, CM11 and Echoe 5.0 not a great deal changed on each after using each one for a couple of days, every day my battery gets hammered by 'android system' and 'android os'. After seeing a post about it I have gone back to stock touchwiz using the 4.4.2 Nordic firmware. This made no difference either.
I have posted some pictures of my battery life since getting up this morning. I always have sync turned off and my screen is always just above the minimum brightness. Im on Wifi a lot between work and home which in theory should use less power. I've been playing contest of champions quite a bit recently which I would expect to be a battery drainer but it is still beaten by my screen and this android system and OS combo. I also don't get why battery dropped around 18% (30 something to the 15% warning) in around 20 minutes which is the red line on the battery graph. Last Friday I went to sleep with my battery on around 78%, when I woke up it had dropped to 42% with no apps left running.
I'm literally out of ideas. I've tried everything i've seen on forums and it hasn't worked. I've owned an S5, m8 and z2 but ended up coming back to a note because they are simply fantastic phones. I am however seriously considering selling this and getting a different phone if I don't figure this out soon though. Can anyone help or is this simply an unsolvable problem caused by horrendous software implementation, or am I being stupid and should be content with 13 hours irregular battery life???

Thats just not normal, try to use app wakelock detector (from playstore) to see what apps are currently running, you can also go to the device app manager and then go to "running apps" and then see what apps are running on backround, that would give you a general idea of where are the battery draining apps. Then all you have to do is to disable/freeze them , using the inbuilt disable option under the app settings or using a third party program like app quarantine (from playstore). Note that i also recommend you disabling apps you dont use , like for example samsung apps etc.

Thanks for the advice. I even ordered a new battery from samsung which arrived this morning but that doesn't seem to have made much difference either. If I hadn't seen similar cases to mine i'd think my phone was broken but honestly I'm starting to think that is down to samsung software and won't ever be fixed. It's a shame because the Note 3 is the best phone i've owned but ill be steering clear of samsung devices in the future

Use Greenify to hibernate apps..it will save ur battery..
Greenify is a big help. Also use Titanium Backup to freeze or uninstall anything with the word 'Samsung' in it that you don't need (they're terrible, in my experience).
Some other things that can help are turning off GPS and Bluetooth when you don't need them, raising your wi-fi scan interval if you typically leave wi-fi on in areas you're not connected, using an app like AutoStarts to control what apps wake up when, and you should check what apps you have auto-syncing, and how often. If you don't need gmail and facebook to sync every 5 minutes (just an example), then change the interval. And unless you spent a good bit of time playing it before you took those screenshots, I would highly recommend ditching that Champions game.
Aside from that, another thing you might want to consider is trying a different kernel. Some kernels are just bad on battery life.
I'm on my original, stock battery, and I get 22-26 hours typically, with moderate usage, and anywhere from 6-10+ hours of screen on time. Right now I'm sitting at 18h5m29s with 5h26m3s screen on, with 27% battery left.

Trying a custom kernel is something else I'd though about. It's crazy that you've got those battery stats. My brightness is always near minimum and I only get 4 hours on a good day. Judging from posts I've read those android os and system percentages are accurate for the note 3 nowadays. I never have sync turned on so that can't be the issue. I've got this phone on ebay now so if I don't sort this out in the next couple of days I'll be moving on unfortunately, bit sad as this is the best phone I've owned

I'm in the same boat. Stock 4.3 with tons of apps frozen, greenify doing its thing and Google Play Services tamed as it was draining the battery. To me everything looks ok in WLD but I have noticed that something called 1013 which is always at the top with most amount of wakes, is that system audio? I also have screen brightness on minimum, powersaving mode on, bluetooth and gps off, sync on and most of the time usually on wifi networks.
I have managed 6hrs screen on before but when using device moderately over 2 days I get 4 hrs screen on time at best, usually 3 or 2.5 hrs.
The 6 hrs was managed when I watched 3 movies in a row, it seems sleep takes more than it should? Wake ups are a problem?

Yeah something has definitely gone wrong at the core of the phones software, especially when different roms and stock firmware builds are making no difference at all. I flashed AEL kernel yesterday so i'm seeing how that goes today. I'll post screenshots when i get home from work, so far my batteries only dropped 10% in 3 hours but thats with 30mins screen on time.
Had similar battery draining issues, I froze Unified Daemon (EUR) this appears to have fixed it.
I have faced this issue after my phone got the last update.
Even the android system was consuming more than the screen.
I removed Google account and put it back again but this time i limited the Google features that do the sync to the required only, gave a full recharge, the second day the android system consumption decrease a bit.
I gave it a full recharge cycle each day for the next 3 days and later it came back to normal.
I hope that helps.

I had the same problem. for months and no solution anywhere. what I did was to downgrade back to jellybean. this is the only thing that seemed to stop the drain. though I still believe my battery was much better on the initial jellybean.

Battery life has suddenly become much shorter

Having been really impressive so far, my battery life appears to have dropped drastically over the last couple of weeks. Previously my battery would comfortably last the whole day, I could leave the house at the start of the day at about 60% and be confident it would easily last the whole day, now I leave the house on 100% and I'm down to about 20% by the time I'm home from work. In particular, whenever I'm down to 14% my phone seems to drop pretty much instantly to 8% .
I can't think of anything I'm doing differently, only thing that comes to mind is I updated my phone via my computer a few weeks ago but no idea if that's connected to the problem. I installed GSAM for a week ago and haven't really been able to pinpoint where all my battery is going, my phone has continued to show a lot less battery capacity than before and also seems to be taking longer than usual to charge.
As expected Screen and App Usage are the main drain on the battery both tend to be somewhere in the 40%-55% region. The only thing which surprised me is that Facebook (which I don't excessively use) is pretty much always at the top of my app usage, often at about 20%-30% of the app usage. So I can uninstall and reinstall this as it may be partly to blame but it doesn't really account for why my battery is dying so much quicker than before. I could also dim the screen a bit to help but I kind of don't feel like I should have to as I've never changed it the whole time I've had the phone so it shouldn't be a cause of why my battery has suddenly got worse.
Any ideas?
I think you have to perform hard reset for your Z3 (maybe some app "eat" your battery), or boot your device in a safe mode and try to recognize what application make battery so quick discharge. Try to use stamina mode.
Did you often charge your phone? After hard reset I recommend you train your battery couple times (3-4 times), for this you should discharge your phone to 1-2% and charge it up to 100% without disconnecting. I hope it will help you in your trouble.
How much screen on time do you get?
I recommend Better Battery Stats to see what's causing your drain(maybe you can attach some screenshots). And yeah FB drains a lot.
Unfortunately I am a new user of this forum and can't post outside links but if you will enter this "These apps are draining most of your data and battery life" words into the google search you will get very interesting article about battery usage of facebook and another very famous apps.

I'm currently having the exact problem. Without making any special changes. My battery has gone from the announced 2 day levels to just surging away in the background.
Here's some pics. https://drive.google.com/folderview?id=0B7QU-WxZhNG0SnZ3ZDV6eVM3WFk&usp=sharing
First is from 26th of February (Named 0226). This was the only picture I had from an earlier date. The rest is from today.

You know, with my old Xperia Z was the same think after update with computer and after I had performed hard reset everything has been ok with the battery. So If you will not try - you will not know. But be careful all what you will do is on you own risk.
I think it has to do with the latest google app update. My battery life has gone down hill this past week after that.
Same here mate!

Phew! Thought it was just me who had the problem. I thought it might be some apps I recently installed. I tried uninstalling them but the battery life seemed to have gone down regardless. Its not the same as it was about 2 months ago. I used to easily end the day with over 45-50% but now i need to recharge it around 9pm when its at 10-15%. It could be the new updates that are rolling in for the various apps i already had installed will install battery stats and wait for a better picture.

Does anyone of you use Spotify? It seems to be the culprit for me. Today I have 0,7%/h drain instead of 3-4% compared to yesturday. Haven't started it at all. Seems to be the problem. It was also updated this week in the possible range for when I noticed the problem

[Q] How do I fix my terrible S6 battery life?

Hi guys. I just created an account to these forums. I've used them before when rooting a previous phone. I have a problem with my new S6. I got it about three weeks ago, and I love it. The only problem I have is the incredibly short battery life. There has to be a problem with my phone, because I'll have a battery life of about 5 hours on a good day, but usually 2 or 3. The phone will get mildly hot, and all battery will drain rapidly. I will regularly lose ~40-50% in an hour after it starts heating up. I've been simply dealing with it for a while, after a failed attempt to find a solution on Google. I regularly close my apps, and I even have powersaver on at all times now. Last night, I closed all apps, then restarted my phone. It was at 98 when I fell asleep. I woke up 9 hours later and it was dead. I have checked the battery info a couple times, but I don't ever see anything rapidly draining battery. Could this be a hardware problem?
I have a Verizon S6 regular. Model number SM-G920V
Try to calibrate your battery first.
I suggest reinstalling the software using Samsung's smart manager and updating to 5.1.1, I never had your issues but noticed a big improvement with battery life. I'm sure you have a rogue app somewhere running havoc. There's also a lot of things you can do to improve battery life after reset, like disabling background data on certain apps that you need need constantly connecting and using data like Facebook when it's not even in use. Just play around with your phone to know the ins and outs

Thanks for the suggestion. Where is the Smart Manager? I Googled it, and found a thread saying
It is included on the phone, however there is no way to access it that I've found. You can find it under Application Manager - ALL. Scroll down to Smart Manager and select it, you will find that the app is running but we are cannot access it and the DISABLE button is grayed out. My guess is that Verizon wants us to use their My Verizon Mobile app instead of Smart Manager. I heard that AT&T did the same thing.

My bad it's actually called smart switch. I just got brainwashed seeing it that widget all the time on my homescreen.
https://youtu.be/y8AZyalTf5Y Here's a video (tutorial)
Follow the Link Of the Video if you can't find the link for the Smart Switch download. Hope this helps
I suggest wiping the cache. I was experiencing a similar issue. After wiping the cache, consumption return to normal.

98% gone during 9 hours of sleeping? wow...
1) Do the factory reset, full wipe and see if its gonna get any better.
2) If still the same problem, then download latest firmware for your model from sammobile.com http://www.sammobile.com/firmwares/database/SM-G920V/ and flash it via Odin / Download mode
If still the same issue, then contact samsung for the warranty :X

You might try a Sprint fix since your Verizon S6 has CDMA too. Since you've got a Verizon phone, this setting may be somewhat different. On my Sprint S6, I changed the setting under 'Mobile Network', then 'Network Mode' to LTE/CDMA' instead of 'Automatic'. That made my battery life much better. I think I remember a friend with a Verizon S6 and it had 'Global' instead of 'Automatic'. So change it out of 'Global' mode and see what happens.

Having headaches with my battery life

So I'm getting pretty bad battery life on my Spring Galaxy S6 Edge. I got the S6 last week and I can still return it to Sprint and get a different phone. (I'm looking at the G4 right now). I've been reading almost every battery thread on XDA and reddit and I just can't figure out how to get better battery life. I'm running the latest stock software. I am not rooted. I've already tried a factory reset and disabled all unnecessary apps.
Right to the point, I get around 2~2.5 SOT on my phone usually with only Wifi on, low brightness, and location set to battery saving. Now, I'm happy with how the phone drains when I'm actively using it. I got about 50 minutes SOT of reddit, instagram, facebook, etc and it drained about 15%.
What I'm not happy about is the idle battery drain/screen off drain. On multiple occasions, I charged my phone to 100% and let it sit over night. I would almost always wake up around 90 or 91% with around 8-10 hours of sleep. Other times, the battery just drains at a crazy 5%/hour. How do I minimize idle battery drain? It's driving me crazy. I don't think this is a problem with the S6 specifically, as I had this problem with my M8 running lollipop before.
I look at CPUspy and it looks like my phone is going to deep sleep around 60% of the time. I'm would like that number to be higher, but I'm entirely sure if 60% is good or not.
On GSam, I always notice that Android System and Kernel are top of the list. Not sure how to tame those. Other apps seem to be doing okay.
So I'm looking for tips and advice on how to make sure I'm getting the best idle drain without going into airplane mode. I know that if I get get idle drain down, then this phone or really any phone can last me all day and get 5-6 SOT. I also read somewhere that reflashing the firmware might help, but I'm trying to see all of my available options before I do so.
Thanks everyone!
EDIT: I'll also try to add screen shots after using it for a few hours!
You may have a defective battery. Return your S6 back to Samsung for warranty replacement.

Disable Location service when you don't need it, it drained lots of battery and install the above ver of Google Services will help battery. A new battery will take at least two weeks to completely optimize the battery.

Sorry, I don't buy that it takes two weeks to fully optimize the battery. I'm not going to take the chance and wait it up and hope it gets better when I can go back to the store and get a new phone.
