Hello,
I'm a first time poster looking for a little help. I've had my Verizon SIII for about a week now and almost everything about the phone I have loved with the exception of the battery life. Given the 2100mah battery I was expecting much more. I tend to be a fairly light user throughout the day at work, I have the screen brightness turned down, all data is off, and I really only am using it for texting, maybe a little bit of gaming. I have found that if I unplug at about 8am by about 6 or 7pm the battery will be nearly completely drained.
Noticing that this seemed to be a fairly common problem I started doing some research to determine the source of this. First, by looking at the battery stats I observed the same problem that many others observe, a heavy drain in standby mode.

So going off of this I started trying to determine the cause of this drain in standby mode. I should also mention that at times the phone does seem to get warm in the bottom left region of the back of the phone. I had read one tutorial explaining about wakelocks so I decided to check that out. I downloaded GSam Battery and CPU Spy to see if something was preventing my phone from entering standby mode properly. However my phone was entering deep sleep as shown below, so this confused me a bit. But clearly there is some issue visible in the standby mode of my phone, sometimes the battery will drain ridiculously fast (as high as 1% every 5 - 10 minutes). And keep in mind that this is while virtually everything, data included, is disabled. So that eliminates the possibility of it simply having to search for a signal in a weak area.

Basically I'm having a tough time getting to the root cause of this problem. I feel like there's some little software issue in there that is draining it. But I've been pretty smart about the apps that I've downloaded, I've stuck with only very common and popular ones. So would anybody have any clue to how I could identify and address the source of my battery drain?
Thanks

You don't have to thank me there is a button for that
Download and try Watchdog Lite. It's a really good monitor for finding out which apps are acting up.
This doesn't exactly answer your question, but can help with your problem. There are programs that can help to drastically improve battery life by turning off data (3g\4g) while the screen is off. This can double your battery life or more, especially for lite/moderate users. Most of these programs work by turning on the data 1 minute out of every 15 the screen is off. That way you still get email, and notifications. You still get txt and phone real time, as they do not rely on data. When you turn the screen on data is turned on, when you actually would want to use it. Especially in 4g areas this really saves battery, as 4g is a battery hog.
Battery Defender is my favorite. I feel like I should be paid for this advertisement...
Do you have BATTERY SAVER option ENABLED in settings? That makes a huge difference for me.
It sounds like you are still stock, but I used the Root66 image and after that started having huge battery drain. I did a factory reset to no avail, so then moved to Synergy Rom. Since then, I've had outstanding battery life! not sure if you were thinking about going this route, but it has worked for me. Synergy is debloated so I assumed Verizon crap to be the culprit.
The images I saw were all at 100% battery. Those are not very helpful. A shot of your battery stats at the end of the day would be a lot more useful.
Please note that Cell Standby reports incorrectly at the moment on the S3. Unless you do the fix linked above, it will nearly always be at the top, but it does not actually drain that much battery, it is simply a reporting issue.
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

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.
So, wasn't really using the phone during that time...
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 :/
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 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

Hello all, so the original battery on my Google pixel, almost 3 years old, went to complete hell. It turns off in about a minute once unplugged, despite 100% battery life. So I went and replaced it with two Amazon bought batteries. The first one (definitely not OEM) had the same issue but my pixel would at least last about 10 minutes of regular use, unplugged, before shutting down. So I thought it might be the battery but the second one has the exact same issue. The second one at least looked like OEM with the exterior but since it came from Amazon, it's not 100% certain.
The problem is that the phone charges very fast, like 100% in less than 15 minutes and then discharges 10-20% in just a few minutes. If I last below 70% that would be out of the ordinary.
Is it possible that it's not a battery issue but maybe a different issue? A friendly person on another forum suggested that my core or graphics IC is overheating, attempting to throttle down; and then just shutting down when it looses the battle. Which makes absolute sense since the phone mostly shuts down when I'm playing games on my phone and usually turns off just under 80%.
I also found out that a recent google play store version was found to be the culprit for the extensive battery loss for other folks. Could this also be reason?
Are there any tests I could do to further determine the actual cause?
Thank you.
Two ideas:
- Deactivate Play Store app in Settings -> Apps & Notifications -> All -> Play Store -> Deactivate
- To rule out a damaged third party app as a cause for the battery drain (which actually is quite unlikely in your case), you can reboot into safe mode. For that, long-press the power button and then long-press 'shut down', confirm with OK. At the reboot, all non-system apps are freezed. Then you can check if the battery behaves differently.
Did you try charging your phone for about two hours longer, even if it says it is already at 100%? Maybe just the battery percentage measurement system is somehow damaged.
But you already tried that I guess. So maybe somebody else got another tip for you.
do you try flashing stock image? maybe the battery cache is in trouble
Similar to OP, my Pixel XL had started to have some odd issues beginning almost a year ago. It got REALLY bad in just the last six weeks or so when it would shut down at relatively respectable battery percentages (something like 23% - 57%, randomly).

Thanks for these ideas, BenjyTec.
When I deactivated ("Disabled" in my settings), there was no change in behavior. In fact, I had forgot I did that until giving things about a week and had forgotten when the phone behaved the same way, LOL (I just now re-enabled it).
I also tried the Safe Mode (which I had not previously known about - thanks!), and the phone still died out pretty quickly from a "full" charge.

I had also done this several times. The really odd thing is many times I will have it on the charger all night or for several hours, and when I take it off it is only at a very low percentage - from 1% to 16%. !!! Of course more often than not it does get to a higher percentage.

Thanks, gonzakennyn - I have not done a "stock" image, but have factory reset the phone, with no joy. This was actually one of the things I did months ago even before it got really bad, because I wondered if maybe the battery cache or something at the kernel level had deeper issues.
Hopefully the OP might have had better luck or found something...
All these complaints sound like power supply issues.
Use the phone while it's in the charger, and there's no overheating/throttling/shutdown, right?

Unfortunately, I did not find a solution. After replacing the battery twice I pretty much resigned to my fate. I'm going to hold out until Pixel 4 comes out.
Once fully charged, I could use my phone for browsing or watching videos for about an hour before I get to around 30-40%. Then I could leave it unplugged all night and wake up to my battery at 1%. It actually stays that way for a bit.
However, if I use my phone to play any games, I could only use it unplugged for about 10 minutes. My phone will power down without fail at 80% or below only when I play games. Weird thing is, whenever I power it back up, my phone will be 1% but despite that it could last quite a while.
As post-mortem mentioned, I could use my phone while charging without issues so maybe it is a power supply issue, in which case, I have no idea what I could do.
When it's not plugged in to a charger, the only power supply is the battery. Hence, I feel that even your "new" battery is not new.
So a little update all. I updated my phone to the latest Android 10 patch and the battery life has gotten significantly better. It's still not enough to last all day but it can last probably 6-8 hours with minimal use. If I use it constantly, it might last two hours.
I am no longer tethered to my charger when playing games, which is really good news and all the prior issues with the phone shutting down ~80% is gone.
Perhaps the previous Android patches contained faulty code?
I would do fresh install and see if problem resolves. Fresh install fixes all sorts of software issues.
So my battery woes aren't as bad as yours but I did get to the point where I had the battery replaced. I went to uBreakiFix and I have no idea what battery they put in but the bottom line is a brand new battery didn't help much. I got a little better battery life but not as much as I had hoped. I'm assuming that it's either due to the apps I have installed and my usage or the phone is getting old and something is drawing a little more power than it used to. I have not gone to the trouble of factory resetting to see if that would help yet.

Factory resets didn't help my old issue. Updating to the latest Android os helped immensely. As stated above I no longer have the initial issues. I estimate I now have about 70-80% capacity, which is not bad at all considering I bought my battery through Amazon for around $20.
I thought if you got your battery replaced at ubreakifix, then they are obligated to fix your issue or refund you your money.
