"Cell standby" suddenly draining the battery

I only noticed this problem after using BeastMOD for a couple weeks. One day, my battery was almost dead by the time I left work in the evening, and this is not normal at all. I noticed that in the battery history, Cell standby was the main culprit, taking up around 30-40%. I have never seen Cell standby taking up so much power until now.
After having some issue with BeastMOD, I installed Juggernaut about a week ago. It was fine at first, but now I'm seeing the same problem with Juggs too! Does anyone know why this suddenly starts happening, and if there is a permanent solution?
I tried to take a screenshot with Juggs, but something isn't working. Time without a signal is 0%, but this reading often doesn't even show up.

This can occur if you are in a place of low signal coverage for a while. The lower the signal quality, the harder the radios try to maintain a signal.

It could be because of the applications running in the background that takes up the battery while the phone is idle.

Correct. Specially if your radio is constantly switching from WCDMA to GSM due to poor reception. Generally if you're on GSM and you don't have great signal then you wont see a dramatic effect on the battery but its the complete opposite when on WCDMA.

This has nothing to do with cell standby.

Yeah, that's how I understand it. What doesn't make sense is that this would happen suddenly, and then not let up. The phone would be running fine for a week or two, then suddenly the cell standby shoots up. I'm not visiting new areas that I don't normally go to. This is only at home and at work - two places I spend the most time at. And both of these areas have good coverage from T-mobile.
When it shows it, Cell standby will show 0% for "time without a signal".
I disabled Juice Defender, and I'll see if that makes a difference in the next couple days. So far, it doesn't look like it. Cell standby is at 29% right now - much higher than normal.

Do you use your phone at all during work and home? I leave my phone on standby in school and it is normal for me because I do nothing else at school with my phone. When I get home and start using my phone, Cell Standby disappears. And the percentage next to the process is the percentage of how much of the battery lost it is responsible for. If your battery is at 80%, and Cell Standby says 40%, it is responsible for 40% of the 20% drop in battery, though I'm sure you know that already. I have never seen a case like yours, though. From what I can figure from the screenie, Cell Standby is a huge problem because it is at 10% battery from 100% in 10 hours and 39 minutes and that is really short for standby only. The apps that I see that take up battery are the same system apps on my phone when on standby. Try replacing your battery, and if the problem consists, then I suggest you UNROOT it and exchange it. If they charge you, argue because after all, it isn't your fault. Your drainage is extreme though, because at 10 hours on standby, my phone would have at least 60% battery left.

I use the phone at work, though typically pretty lightly. I don't see how this could be a problem with the battery. The battery isn't telling the phone to do anything, just supplying it with juice. It's very inconsistent, though now I've experienced the problem with two different ROMs.
I've plenty of references to the flight mode "trick", where you turn on flight mode for a few minutes, then turn it back off. I don't know what this is supposed to do to the system. I had tried this before with no luck, so this morning I put the phone in flight mode for half an hour. Currently cell standby is only at 12-13%... we'll see if the problem comes back.
I bought the phone from wirefly, and it was back in October. I don't know if I can exchange it anymore... RMA with Samsung, maybe...

Yeah. Samsung is your best bet since you didn't buy it directly from TMO. I also had the same problem except that the culprit was IMS Service. I uninstalled that, but I'm not sure about your case. IMS wasn't essential. Cell Standby is and I don't think you can even uninstall it.

Are you on an actual ICS ROM? That might be the problem, since we don't have our own KERNEL for it. Try flashing Bombaridier if you are on ICS. GB might fix the problem. Or flash EasyDoesIt which is also an ICS ROM, though I haven't let the battery settle for a couple of days. For the most part, it was normal for me.

I know this is a pain-in-the-ass suggestion, but you might want to try reflash back to stock 2.3.5, do the OTA upgrade to 2.3.6 (which should reflash your modem), and then see if the problem persists. This would completely rule out any kind of software/firmware issue.
I still think it's likely a signal quality issue, though. Not all signals are equal. Just because your phone a strong signal doesn't necessarily mean it has a strong 3G/4G signal. The signal icon can be very misleading and will often display the "4G" signal even when it really is only connected to 3G bands. The radios will constantly try to "step" up to the next band by testing the signal. This process consumes excess battery power. Have you tried setting your phone into 2G only mode and determining whether the problem still occurs? I'd also go ahead and turn off Bluetooth, WiFi, and GPS radios while you are at it.

I just might have to try going back to 2.3.5. I did flash the 2.3.6 stock ROM and was using that for a long time before trying out Beast and Juggernaut, though. Does that not flash the modem?
The reason why I flashed 2.3.6 instead of doing the OTA update was that after I un-rooted and went back to stock 2.3.5, I didn't get the OTA update message and Kies wouldn't update me either.
How do I selectively turn off 3/4G? I only see the "Use packet data" option.

As I understand it, flashing a 2.3.6 ROM does not update the modem. It's the same reason a nandroid backup won't backup/restore your modem. You should be able to find out pretty quick by going to Settings > About > Baseband version. It should be T989UVKL1 for the stock 2.3.6 Hercules modem.

My baseband version is T989UVKL1, so apparently I'm using the 2.3.6 modem.
The problem isn't happening today. Cell standby is at 10% at the moment. I turned off packet data this morning for a few hours, and turned it back on around noon. If the issue comes up again I'll try switching to GSM only and see if that does anything.

The problem came back a couple days ago while I was at work. Around noon, I noticed that Cell standby was taking up over 30% of my battery life, and the battery was draining much faster than normal. I turned off Wifi and left it like that for the rest of the day. I checked the battery usage periodically, and the Cell standby percentage steadily dropped till it was in the low 20's. That was a couple days ago, and I've left Wifi off since then.
Today, Cell standby is at 11% and the battery usage seems relatively normal. I'm at 63% after almost 6 hours.
This makes very little sense to me, but I'm putting it out there anyway. I know there's a problem with one of the wireless routers at work when PCs connect to it, so maybe my phone is having issues with it too. Still, though, I don't know why that would affect the cell radio. There are several different wireless access points at my work, so I'll try those out too.

Do you have wifi calling enabled? If your wireless router has signal problems, this could cause the same effect as cellular signal problems... it could be constantly switching from wireless calling to network calling and never letting the cellular radios enter their sleep states.

Let's not spread false info, our device is not 4G at all. LTE is 4G period.
To the |OP|, 1st off get rid of that juice defender crap. I have ran both ROMS you have named in an area that gets horrible service coverage. I have no problems with cell stand by even with wifi, GPS, data, & sync enabled. I was still pulling about 23-24 hours with moderate use. Enable wifi calling to curb the modem changes when you are in wifi range. Wipe cache, davlik and battery stats. If that persists try the new blaze radio in the dev section. I wouldn't recommend going to stock and OTA to anything. All the stock roms have a bunch of bloat that eat battery and data. Report back your findings and we will see how to help you further if this doesn't fix the issue.

I don't have wifi calling enabled. I tried it a few times when I first upgraded to 2.3.6, but it didn't work very well for me. The sound was scratchy and noisy, so I disabled it and never looked back.
For the last couple days I shut off wifi completely, both at home and at work, and this has improved the battery life. Yesterday, after about 14 hours, I was still around 40-something % (I wanted to take a screenshot, but screenshots aren't working with Juggernaut on my phone). I have been using the phone pretty lightly the past couple days. Cell standby was in the low 20% range.
I will try another wifi hotspot at work to see if that helps. Just curious, what do you have your Wi-Fi sleep policy set to?
Edit: I have had Juice Defender disabled for a while now. It didn't seem to be the source of the problem.

Save Your battery

Well folks, I took time to study our G2 battery to really see what is killing it. After testing it on different roms i have come out with something that can save your battery for a while before you think of replacing it.
On a general scope these are the main factors that really drain your battery:
1.3G data connection
2.Screen brightness
3.Rom type(mostly sense roms)
On 3g, if the user has a wireless network nearby i suggest you connect to that for your browsing and all that, there is no need using hspa when you have a WI-fi network working great, 3g networks drains the battery faster than you think i tried it and i saw that the WI-fi use was very slow in draining the battery up to the point i switch to 3g. IF your thing is voice calls i still don't see how good and different 3g is from 2g "it's not like you are recording an album over the phone to need such voice clarity" remember a good battery life affects your phones performance in a great way. these photos tell the whole story..

i used the wi-fi for about 12 hours and when i switched to 3g it drained in 2 hours
For screen brightness you will notice that every time you check battery usage your screen always has the biggest share of the consumption. You have to reduce your screen brightness to 30% or lower or put it on auto-brightness that's about all you can do about it.
Also your rom and the kernel it comes with are a huge factor in battery consumption. On a general scale i have noticed that sense roms are the big killers of all just see
in 51 mins of no use at all just screen off the battery drops to 81% i have never had above 9 hours of use with any sense rom
Other things like gps also drain your battery, so if you are not on "MAPS" just switch it off to save your battery. Also keeping your cpu clock speed at high points drain the battery a lot try to use apps like setcpu to control the clock speed and set profile like screen off to keep your cpu down when you are not using it, and use cpu governors like smatass, ondemand, conservative etc
Also the trick of draining your battery completely and then recharging it in intervals of 3 months or more help enhance battery life,
do not leave lots of apps running in the back ground they also drain you battery alot :good:
Any body who knows something that can help pls add cos there are a lot of guys who still don't know these stuff....
and a lot of guys like me who still want to enjoy their G2 for a looooong time....so big boys...yes it's needed......

photos missing.......................................................................................................

About the sense roms, even though i agree it consumes more battery than AOSP, they are not as bad as u say (at least not all of them). I use a sense 3.5 rom and with regular use i get about a day and a half before it hits 20% (80% consumed) (This is on 2g, with wifi on... when with data on, i still get at least 22 hours). I know it comes down to settings and usage, but just saying, its possible to get a lot of battery endurance with sense.
If anyone is interested in more detalied information on my settings and usage, feel free to ask me (through pm if possible)
Nice review though, thanks for sharing!

This is impossible if you havent got a problem with the rom. I have been using all kinds of roms with my Desire Z. The battery life is not that much different on sense and aosp roms.
I am using GenY Beta5 right now for example. On standby mode (only gps is disabled) it can go more than 2 days! A stock optimized 2.1 Sense rom can go even more than that.
For battery life problems I suggest using an app like Better Battery Stats and see what is causing your phone to stay awake. It is easy to see what eats your battery.
Other than that as you said, whatever rom you use Screen will eat your battery the most. Overclocking will obviously eat more battery too. Using 3G instead of 2G will use more battery. COnstant Wi-fi activity and gps are battery killers too as you may guess.
The rest is how the user uses his/her phone.

All you are saying are basic stuff everyone knows about power consumption, and all that you have been testing are YOUR results, what you are saying now are absolutely no facts, and some are wrong. You're saying sense takes more juice? Well since IceCreamSandwich it doesn't really matter. Are you sure your battery is properly calibrated?
After installing a rom you shouldn't put the phone on a charger, but just use/leave it till the battery has 10% left. then charge till its full. By prefer you should do it another time and then it should be calibrated.
Also you forgot to add the radio. The radio is also important, if you got a proper radio for your provider/rom, you can easily get more power out of your phone. If you have the wrong one, drains can be high. The extremest example I can take is my old HD2. Which had a radio not compatible with the version of android and the battery drained from 100 - 10 in 3 hours.
Now look at my stats of my DesireZ, running Gen.Y RC1(Which seems to be using more battery then the B5). I attached a screenshot. The battery is totally stock and not an extended one. I used it yesterday at home when I was busy with my car(whatsapp, mail, google), at the evening I played some games. Before I went to bed my battery stats was 60%, when I got out of bed this morning it was 59%.
Also I think the topic should be in "general" since its talking about everything, and I can't see how this is rom development.

Thanks for adding up guys,but I am sure your batteries are quite fresh that's why you have very good batteries,people like me with aging ones who still want to use it for a while. I had to wipe my battery stats a few times to calibrate it. And if your read things very well this was meant for guys who really don't know the does and donts about battery usage yes it's basic but people still ask these questions in dev sections. I did not add radio because that thing does not work well for everyone and it's still an easy way to brick your phone most of these radios were made with USA service providers in mind ,people have complained about having serious issues with battery and connectivity when they Change their radio and if any one is even reading this then I don't think that person even knows what the radio is so why not do the basics than brick your phone in an attempt to go high .....to the big boys who know all.... you have to know that there are still guys out there without rooted phones facing these problems so radio is the last option......

If their phone is not rooted, how can they have a custom rom then lol. I think if you want to use a custom rom on your phone you should read everything and not blindly start everything. Also flashing a radio has risks, but not really something to worry about if you do it right. Its quite easy and as long as you stay on the right path you are fine. If you want to make a proper thread about battery consumption you should include the radio thing. And also post it in a place where it belongs. You are right that newbies don't know everything, but if we should do everything for them, you get even more newbie questions. They need to put some effort in it like we do.

also you have not added the tricks like changing the advanced wifi to always wifi when screen off....

[Q] Battery Drain

Is anyone experiencing battery drain? I'm getting through a whole day on light to moderate use but I believe it should be better. It's seems to be draining during times when I'm not using it. I turned off the connection optimizer and got about 7 to 10 percent back but I'm still seeing drain that I shouldn't. I'm not using many apps beyond stock. Power Screen says most of my power is in "Android System" usually in the 25 to 30 percent range. Problem is android system is like 30 services. I may just root and start freezin stuff with titanium until I find the culprit. I'm just curious if anyone else has noticed worse than expected battery life

Yeah I've seen android system at the top of the usage list everyday and don't know why. I get about 5 hours screen time but feel like it could be better if there wasn't drain somewhere from android system
I plan to root today and see if I can narrow it down as well

There's suppose to be a system update that will pushed to our phones that has the battery fix. T-Mobile guys already have it...no clue when we will see it

Yea I'm waiting on that update and keep checking. There's nothing wrong with the battery life I just feel I should be getting more. Seeing people get 5hrs of on screen time and I'm only getting 2-3hrs and when I get home I have like half my battery life doesn't seem right. I feel like my battery should be giving me more than that if I'm barely using my phone while at work.

Very huge possibility as my receptions suck in here and I use wifi connection (also WiFi calling profile update message notification is constantly popup up even if profile is updated). Other thing is also I heard sprint should release software update for battery fix on note 4. Last things is battery should hit several cycles before it hits it's maximum and I just got mine last night.

Has anyone seen anything from sprint on whether they're going to push out the battery life hotfix anytime soon?

Sprint Forums are very active with people complaining about battery life and battery heating up issues.
Although sprint doesn't seem to want to acknowledge that samsung has released fixes for the battery.
https://community.sprint.com/baw/message/873447#873447
Here's the link to all the complaints:
https://community.sprint.com/baw/thread/175655?start=0&tstart=0

This is apparently the firmware version that the fixes are in:
Note 4 Firmware Update XXU1ANJ4

Talked to samsung they claim there are no firmware updates for the Sprint Note 4 and no plans to provide any for anything relating to battery drain.

After playing around turning lots of things off I can now get through one day with very light use. The two biggest helps for me were turning off the connection optimizer and turning off the wifi. The primary reason I think the battery is draining is that while the wifi is on if your not connected to any wifi networks it scans for networks every 10 seconds. Even if you are connected to wifi it scans for networks every 10 seconds. I don't know if this is the primary reason my battery is draining but like I stated in previous posts I'm stock, I've got very few apps installed. I was barely able to make it through a day with this monster 3220 mA battery. Pretty disappointing for the cost of the phone. Both sprint and samsung are completely useless to talk to. They suggest all the same sh?t that I've been doing for years to improve battery life. I will they'd release the firmware that was released for t-mobile and a number of the international versions. It's been done on like 6 versions that I could tell last I looked.

While it's far from guaranteeing an update, it is disingenuous by Samsung to claim that they have "no plans to provide" as the NJ4 rdf is up on the Sprint website (albeit unpopulated). NIE and NJ4 are the only two RDFs I've been able to find, which indicates Sprint at least has been provided the NJ4 patch. Only time will tell if Sprint actually decides to push it to our devices.

I'm not bragging but I'm getting excellent battery life. Couldn't be happier with it. I'm not rooted, yet. Most days I'm getting 8-9 hours of screen on with what I consider to be moderate to heavy usage and 18-22 hours between charges so it is possible and I'm not turning everything off to get it. I'm using my phone the way I want to.
I text and use WhatsApp. Lots of XDA and YouTube. I play some games, though usually not ones that really tax the phone. Constantly looking at Business Calendar Pro. Using the finger scanner to unlock the phone frequently. Using the pedometer, the SpO2 sensor sometimes. Connections Optimizer is on. I leave WiFi on all the time whether I'm connected or not because I use it to trigger my Tasker profiles though I am connected to WiFi almost all the time most days. Brightness is turned almost all the way down when I'm home which is most of the time and when I'm out I have auto-brightness on. No Bluetooth. No NFC. Mobile data off when I'm home on WiFi. I use Greenify to hibernate apps like Facebook but since I'm not yet rooted it doesn't do it automatically. I hit the hibernation widget when I think of it which is only occasionally.
Anyway I'm not sure why I get such great battery life and others are having so much trouble. One thing I probably do differently than most people is something I learned to do on my S3. I noticed when I first got it that if I unplugged it soon after it hit 100% charged the charge would drop somewhat quickly. I've been using Battery Monitor Widget for years so I started paying more attention to it and found that even after the phone said it was 100% charged and I should unplug it, it was still charging at a decent rate. I started leaving it plugged in until it dropped to receiving 1-2 mA. After doing that I noticed a significant improvement in battery life. I got a ZeroLemon extended battery for the S3 and continued charging it the same way. This worked especially well with the ZeroLemon and I actually found it to be extremely necessary because if I didn't let it charge that extra time the battery would lose 15% in about 10-15 minutes, screen on or off!
I tested unplugging the Note 4 soon after it hit 100% when I first got it and the charge dropped somewhat quickly. Switched to my old go to method of letting it charge until it says it's only getting 2mA and I started regularly getting 7.5-9 hours of screen on. I don't believe this to be a placebo effect because it worked on the S3 with the stock battery and the ZeroLemon and now the Note 4 stock battery. It works for me! Anyone having problems with battery life might want to try it. For my Note 4, this usually means charging it for about 1 hour and 40 minutes after it hits 100%. I realize a lot of people may not have the time to do that.
Oh and I also noticed that if the phone is left plugged in for hours after it hits 100%, such as charging overnight or even just charging for a few hours after hitting 100%, the charge drops fairly quickly so there seems to be a sweet spot, IMO. I charge it just about an hour and 40 minutes after it hits 100% and it does great.
Apologies for the ridiculous length of this post. LOL Hope it helps someone!

Does leaving mobile data off when in Wi-Fi really make a difference? I would think that since you're connected to a Wi-Fi network you're only using that and battery should reflect that accordingly.

If you're referring to what I said in my post about turning mobile data off when I'm home on WiFi, I honestly don't know if it makes a difference. I live in a bad spot where my phone jumps between 2 towers constantly and there is LTE but I'm on the very edge of it so in the house, off WiFi, it goes between a lousy 3G connection on two different towers and then occasionally connects to LTE for a few seconds then back to 3G. I just thought it would be better to turn it off since I'm not using it. I'll test it on my next battery cycle or two and see if there's any difference because I really don't know. I was also thinking that with the connections optimizer it might be helpful to have data turned off. I've always done that. I'll test it though because it's a good question.

I was.
I did leave my mobile data off overnight and was getting notifications from textra that it couldn't download an MMS and it took me a few mins before I remembered that I had toggled mobile data off. I thought MMS could download over just WiFi? If not this doesn't seem like a viable option for me during non sleeping hours.

Cm11 may have a battery drain issue with wifi and cell standby.

I flashed cm11.
It seems good.
But, my fire phone use 50% of battery with wifi and cell standby.
I tried to wipe and install 5 times over, but battery drains yet.
Do you have a solution with the problem?
Thank you . :crying:

Never had a battery problem with any of the builds. Going 2 - 4 days with full charge, depending on usage. I guess that's because I treat my battery like a ? .

My battery's been very efficient. In fact, right now I'm just letting cm11 handle it without greenify and amplify because I think its doing a pretty good job all by itself. Are you sure you're reading it right? 50% seems like a big number but if you're checking it right after you flash the ROM its not gonna give you really useful info. Try using something like better battery stats to give you a detailed explanation and wait a few days so you can really see what's going on. In the mean time you can look into your apps to see if any of them are waking up excessively and causing drain. Facebook used to be a killer but I can't say if that's improved because I don't have it installed right now.

I was going to save this for a few more days when the testing was complete, but I figured I can give you all a sneak peek....
I have 2 Fire phones currently running on the T-mobile network. These are my wife's and my backup phones, so I've had the luxury of doing the following:
Her Phone - FireOS 4.6.1 with Google Play and Google Play Services (and the two other needed files) installed.
My Phone - ggow's CM11 (7/25 Build) with pico GAPPS.
Phones were both charged to 100% and placed side by side with cell network and wifi on, mobile data off. No social media apps installed. Only thing syncing in the background is emails (and my wife and I receive a similar amount). Phones have been left alone with just the occasional screen on to peek at the progress.
4 days and 21 hours into the experiment, the FireOS phone is at 23% battery remaining, while the CM11 phone is at 45%. At this rate, the FireOS phone will probably conk out just short of 7 days, while the CM11 phone should last ~9 days.
ggow has given us a beautiful gift.

When you have collected some data with "Better Battery Stats", feel free to post some screenshots.
I used GSam Battery Monitor in the past to get an in depth view.
Example screenshots from Kernel Adiutor & Gsam (Everything's fine, deep sleep state, not too many wakelocks, etc.):

I've found the fire to have the best battery of any Android device I've owned and I'm still on fire os with a different launcher. I put this down to the less deep integration of gapps when sideloaded. Most wake locks seem to be Google related for me.

And the final tally....
I forgot to post the final tallys. For those interested...
Phone with FireOS gave up the ghost at 6 days 15 hours
Phone with CM11 lasted almost exactly 2 days longer at 8 days 15 hours
Granted this is with no use, but it is indicative of how much juice the core OS uses just to keep the motor running. Thanks again, ggow.

Weird. I am using mine without a sim chip, airplane mode, and getting cell standby battery drainage. Didn't even last overnight with no usage at all from 100%. That'd with airplane mode and wifi enabled, by the way. 57% cell standby. Anything to disable service wise?
Would you mind running an overnight test without a sim in it?

You're in luck. I have a 3rd Fire phone I have running on CM11 that I have no SIM in with Airplane mode on and WiFi on. I walked over to check and the phone just happened to be at 1% remaining....checked battery time. 10 days 20 hours. (battery stats report 100% phone idle battery usage).

Aargh! So what am I doing wrong? Is it an app, perhaps, causing the phone to get activated? I'll make a new rom slot and flash it again without adding my Google account and see how that goes. Is there a way to see what apps are causing things to get activated?
Do you have just cm11 loaded, or cm11 and the minimal google apps stuff?
Thanks!
(Though honestly this is just for nerd fun - having Google apps and fireos with the now launcher pretty much meets my needs, but I gotta know! )

- You can use Betterbatterystats to see what is causing wakelocks. http://forum.xda-developers.com/showthread.php?t=1179809
- Minimal Google Apps installed

So I created a new SafeStrap location, and loaded JUST CM11 8/10 build, and with Wifi On (or in Airplane Mode), I get about 7.5%/hr battery drain according to Betterbatterystats.
Says No Data Connection 75% and No or unknown signal 75% of the time. I'm not really educated on reading the BBS results, so anyone know of a pointer? Like 7% of the time it is at 2.15 GHz, and 91% deep sleep - that normal when it's idling?
Strange - doesn't do this in FireOS. Is this partially BECAUSE Google Apps aren't loaded just yet? My other slot has the Google Apps, and it happens as well.
Thanks!

They ain't paying attention. WHY???

Yep missed that requirement. Trying. In a non flashable state after wiping stock. Will try again tonight. Not sure why the slot would affect battery usage but I'll give it a go.

well, bang me upside the head. Hope my pain is the world's gain, but yeah, looks like if you actually follow the instructions, you don't get the battery drain. Had to wipe the stock install, then left with nothing on the device, couldn't boot, couldn't mount over USB to transfer the file, device manager was grumpy about the phone, but after sorting that out, figuring out how to adb sideload, all is working again. Whew!

Just confirming - after I deleted the weather channel app (taking 30% of the battery), I experienced about 1-2% battery drain overnight. REALLY remarkable, actually. This is without email syncing, wifi disabled on sleep, etc. Nice. Really makes the fire phone a good usable device. Or at least and ipod replacement for the kids.

Battery problem (sudden drop below ~30%) even with new battery

Hey Guys!
I have a problem with my GT-I9195. I bougth it from second hand because my last phone's MB has died.
My battery was fine if charged over 30-35%, but nearly that point it drops by 1% every 4-5 seconds.
I bought a new battery because I thought it's just simply the battery. No. The problem persists.
With another charger, it persists too. I have stock rom, rooted and installed TWRP.
Mainly using root just to integrate system apps' updates.
I went to a service guy, who said it can be a processor problem, since the processor controls the charging.
My thoughts are the following after reading n+1 topics on xda about this:
Clean fresh stock ROM install - I don't think it will help me out.
Custom ROM - I think it will be worse.
Custom (maybe just fixed) kernel - ??? (I think could be viable.)
Changing mainboard, because processor controls charing and it may be failing. - I dont think so......
Changing this part in the phone:
Picture
Any suggestions, please?
Thanks in advance!

I have the same problem ... except that the battery will drop really quick when it hits 15% and die within a few minutes. As long as I keep the battery charged above 15%, all is fine.
I have tried the following:
1. "Re-calibrating" the battery - Let battery fully discharge till phone shuts off. Then charge till full, and restart phone. Rationale for this is that the phone may have an incorrect battery stats file, and thought the battery has more charge than actual, so even if the phone said battery is 15% (or whatever), the battery is actually dead.
This did not help me.
2. Install "Better Battery Stat" app, and monitor battery usage, in case a bad app is draining the battery. I did not detect any abnormal battery usage .
3. Clean install ROM. I was on stock, and I installed CM13. This did not solved the battery dying at 15% problem, but extended my phone's battery life. (I can routinely run 36 hrs or so with light usage before hitting 15%.) I presume this is due to getting rid of all the Samsung bloat ware. <Or maybe there was a bad app in the prev installation.>
I am now on Lineage 14.1 (Android 7.1.1). This ROM gives me ~10% improvement on battery life (compared to CM13), which I presume is due to improved Doze mode.
ATM I am getting good enough battery life out of the phone (~3 hr total screen on time, and up to 2 days of light/ mod use), so I have not pursue this further. I am simply treating this as phone not reading battery level properly and work around the limitations.
If you haven't, I would try the re-calibration trick. Didn't work for me, but may work for you. I have good luck going with custom rom (Lineage 14.1 by Arco is what I would suggest.) It extended the battery life of the phone to the point that I don't mind losing 15% capacity. <Might not work for you at 30% ....> I have seen some custom kernels that are supposed to give you faster charging (presumably by altering the charge rate algorithm). I don't think this would help as the problem appears to be problem of phone battery discharge / or the phone reading battery level correctly. <And messing with the charging algorithm is likely going to shorten battery longevity.>
Good luck. If you find a solution, please share!

I think most likely is that both your batteries are old, as the sudden drop is typical of old batteries. Even though you got a new one there are lots of dodgy batteries, according to many sources, sold on ebay etc so I suspect you have one got a bad one.

I did a clean install using TWRP recovery. I downloaded the zip files for Lineage (from xda thread) , and OpenGapps (ARM, 7.1, micro) from http://opengapps.org/ (both to my SD card). From TWRP, I did a factory reset, then the install option. I selected both the files and hit (swipe) install. Worked like a charm. <Also did aroma as well, and that worked too.>
You are supposed to be able to first install the ram, then install OpenGapps at a later date. However, I had problem with the 2 step approach with my HTC One, so always installed both zips together since.

Hello guys!
The battery drop problem is a common failure with this i9195 phone. I did a research but you have to help me as well by providing IMEI S/N (located under the battery) in PM to me!
New battery doesn't helps!
My current research: If your phone made in Vietnam in the 1-line ~2013, then you will have a dead motherboard soon, before that battery issue is occuring.
So please give me your details and I will look after it.
Do anyone know when they stopped producing i9195 and i9195i ? I need to buy the latest version, because my i9195 was made in 2013 and have that battery drain issue even with new batteries...
Thanks.

Good, should be OK then, but keep in mind it's quite possible fake Samsung branded or genuine Samsung batteries that have been "reconditioned" find their way into shops.

Very interesting! I've thought for a long time there must be a bad batch that had a memory problem given the number of bricks on the S4 Mini thread. Though I did wonder if it was more likely the actual memory chip.
I've not seen anyone link the battery issue with the memory problem before, though it's possible, was there something that confirms this or just an educated guess? (edit: it has been suggested before that a low battery level could cause a memory corruption, though that seemed to be as the phone was shutting down not just losing charge quickly)
No, I don't know when they stopped mfg.

I flashed yesterday with these TWRP 2.7.1.0, worked like a charm.

I had some problem soon: From 100%@2AM it discharged to 0%@10AM.
I did not even touched the phone... Kinda weird.

When I plugged in the charger, it said 15%....

I think the problem could be that 2.6.x.x cannot do this.
I flashed yesterday with these TWRP 2.7.1.0, worked like a charm.

I had some problem soon: From 100%@2AM it discharged to 0%@10AM.
I did not even touched the phone... Kinda weird.

I used the latest TWRP (3.0.2.1) to flash mine.
Can't say why you have that big drain at night. Perhaps an app updating? <And after a fresh install, many app will try to sync, etc.> Had that happen to me before - app tried to update overnight and killed the phone. <Bed room have patchy internet, and the constant reconnecting of a shaky internet signal drains the battery fast on my phone. <Now, I only allow update when phone is plugged in.>

that screen shot suggests it must be an app as 63% is very high if the phone was not used overnight, also if that was over night while you were sleeping then screen on time is high also. I would use apps to investigate wake locks and an app that shows cpu use for the app (unless your battery app shows each app)
But I still think there is something amiss with your battery as it shouldn't shut down suddenly from over 30% even using power at that rate with a good battery

You also may to try to download 'Repair battery life' from Play Store and it is free... After fully charged battery you may try also to calibrate your battery if you your phone is rooted and there are also few free calibrating apps on the Play Store with instructions how to do it...
Succes !!!
