Hey guys, I'm new here. I've had my phone for nearly a month now and have constantly read the forums but never posted. I tried finding a thread like this, but I couldn't. Sorry if this is repeated.
This is the second captivate I've had. The first one completely bricked after doing an OTA update. Anyways, after getting a replacement model, I've noticed that the new phone has horrible battery life. Sent about 15 text messages and my battery died 10%. With my old one, I was so amazed at how well the battery lasted.
Is it a well known thing that battery life varies between captivates?
EDIT:
Here's some background on my two captivates (if for some reason it can aid in figuring out why my second captivate's battery life sucks):
With my first captivate, I did an OTA update for JH7 and had amazing battery life. This was when I had "new phone syndrome" and played with every app I could find throughout the day and was always amazed at how the battery wasn't dying quickly (so I'm sure it wasn't my imagination that the battery life was better). I spend nights where I purposely tried draining my battery after coming home from work so I could do a full charge.
Then I installed Cognition, but liked the stock version so I switched back using Odin. After restoring it to JF6, I did another OTA update for JH7. The update froze and then bricked the phone.
Once I had my phone replaced, I used Kies to update to JH7 instead. And for some reason, this phone's battery life is substantially different than my original one
I just notice that Launcher Pro drain the battery faster than TouchWiz.

Check your cell standby. I find that sometimes my standby time shows twice as long as my phone has actually been unplugged. During these times, my battery life is much worse. Not really sure what causes it as it does not always happen... I have not noticed a relationship to Launcher Pro. When the standby weirdness is not an issue I get great battery life with Launcher Pro. I have not used touchwiz in a long time, but I find it hard to imagine that I would be getting better than 18 or so hours with it.

Standby shows the same time as the time that its been unplugged. I started off this morning with 98%. Sending 20 texts plus 2 levels of angry birds dropped it to 81%.
My original captivate had ridiculously good battery life compared to this one. I used it consistently and by the end of the day, still had at least 50%. I doubt its the battery because when they replaced my phone, they put the same battery I had into the new one.
Have you guys experienced any differences between the battery life of two different captivates?

Thanks, I've read that before when I was lurking the forums. I instantly thought it was my imagination but that's not the case.
Also tried the battery draining. Used it until the phone shut off. Charged it to 100%, shut it off, charged it at 100% again. Turned it on, shut it off and charged it...no change.
Att is sending a new battery so I'll see if its the battery that's causing this poor battery life.
So far though, I really doubt its the battery and something in the system. I got so annoyed with the battery life that I did a factory reset in-case there was some app that was draining it, but that didn't help either.
Just a tip. I was using latitude and wasnt getting the normal battery life i usually was when i wasnt using it.
I didnt know it was effecting it though cause you dont see it in task manager but you will in applications/running services. Anyways i signed out of latitude and battery life is back to normal.
It wont be remarkably better but it was noticeable to me. Just a tip.

I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.
Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!
Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.
I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.
I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.
Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S
All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help

Yeah I set it to WCDMA Only. Battery life has been awesome lately.
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
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.

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

Ive done all three methods youve mentioned before and still same thing. Also im on 3/4 bars with lte 90% of the time so no reception issues here. And with my current setup ive been running it for about 2 weeks.

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

Ive always let the rom settle in and i constantly maintain the brightness on around mid level (mirror screen protector so i cant go too low) but its not just one rom or a few, its with every rom i flash ad that consists of most roms available for this device
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 :/
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.
