after having AccuBattery running for a day or two I decided to do a full charge so that it can get more accurate readings out of the battery, specifically in the Health section. after the readings said that the battery was at 100% I disconnected the charger and that's when weird things started happening. The first one was, I wasn't able to make a call outside to a specific number but I can make calls to other numbers. The other issue was the battery reading kept jumping up and down within 4% of each other - it will drop from 100% to 97% and then go back to 100%. The calling issue and the battery reading issue both persisted even after two to three reboots. as a turning off the phone and leaving it off for about a minute I turned it back on and phone calls or back to normal but the battery reading still is not as it keeps jumping back and forth. has anyone seen this before?

Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
Hi. I searched for an answer to this weird problem but couldn't seem to find a similar issue. So here it goes.
When my phone is off and I plug it to recharge the battery, after a due amount of time (or even the whole night) the indicator shows a full green battery and states 100%: fine. But ... as soon as I turn the phone on, the percentage indicator in the top right every time shows a figure between 82-84%. So I need to plug the charger back on again (this time while the phone is on) and after a while I get the 100% on the indicator.
This has happened since I bought the device and with both my (new) batteries. Pointless to say, I did try to reset the battery stats a number of times to correct the issue. No joy.
Am I the only one experiencing this? Any clue on how to fix this discrepancy? Granted it's not a big deal, but still a little annoying.
Thanks
Mike

What might be happening is that your device uses a lot of power in order to boot up. 16% of battery life seems a bit strange though.
The other thing that might occur is that the threshold for the green light to be lit is at about 84-86% (meaning: if the battery is more than 84% or something charged, show the green light).
What I suggest doing is just leave your phone on all the time and perhaps reboot it only when necessary.
As far as I know, there aren't really any solutions, but maybe you should try contacting support from the manufacturer of your device. Perhaps they know more about the subject.
Thanks exenia121,
It's definitely a weird thing. And i was more curious to know if I was the only one to report this. There must be probably a strange surge on boot up. In fact after the recharge of the phone (while being on) was completed (100%) I turned it off. But when I powered it after a couple of hours I was back at 84%. Hmmm ....
I bought my phone new when the Galaxy S6 first came out and have not rooted it.
For while now my battery life has been bad but consistent, or I would say acceptable given what is running in the background. With normal usage, including connecting to a bluetooth watch, LTE, and location services on, my phone battery would drop from around 100% starting at 7am to around 70% by noon. On weekends when I'm just at home and have it on Wifi instead and no bluetooth, it takes until around 6pm to drain to 70%. These numbers have been consistent, give or take 5% for over a year.
The problem started recently when I received an OS update. I can't remember if I was already on Android 7.0 before this update and it was just a minor update for something else, or if this updated me to 7.0 from 6.x
The first week after the update the battery was great. With no change in the way I use my phone I was able to go the entire day without recharging. By noon I was still at 85-90% and by around 7pm it showed 60-70%. So I was able to go the entire day without recharging for almost 2 weeks after the update.
The problem started 3 days ago when suddenly the battery is draining like crazy, and it seems like there's something weird with the battery indicator and the way it's charging. Again, nothing has changed in the way I use my phone.
Now, when I use it, the battery will go down by 1% every minute. And even when I don't use it, it will be down to 70% by 8am and 20% by noon. The stranger thing is when I try to charge it.
Before, with normal use, it will take around 1 hour to charge my every night. Also, the indicator showing how much time is remaining is pretty accurate as well. Now, when I charge it, it seems to take a lot longer. The time indicator will sometimes fluctuate. It may show a realistic time like 45mins remaining, then change to 10mins, then back to 45mins. Also, the times seem to be incorrect. For example, before if I'm at 85% it might take another 15-20mins to reach 100%. Now, it will be at 85%, say it will take 40mins, but after 40mins it's still only showing 90%.
I tried restarting my phone normally, and resetting it by pressing the the vol down and power buttons. I also tried other power saving methods like forcing apps to sleep when I'm not using them. But for some reason, the battery is still draining like crazy.
At this point, given what is going on when I charge the battery, I'm wondering if the real problem is the OS update screwed up the way the phone is reading the battery's power and not that the battery is actually being drained. Maybe the battery in fact is still at 70% by noon even though it says 20%.
Sorry for the long post, I just wanted to be as detailed as possible given that this seems to be different from some of the other battery related problems I've read about on the forums.
Any help or insight will be appreciated.
replace the internal battery
I came here because I have a severe battery drain issue. Sometimes I can fix the issue by rebooting the phone and then not using it. This issue has been coming and going I think since android 10 but it may have occurred in android 9. I had this issue a few months ago and the issue stopped on its own. To workaround the issue I was rebooting the phone when I noticed the severe drain and then tried to avoid using the phone.
For example I charged my phone (pixel 1 XL) before I went to sleep. I charged it to about 85% at 11pm. I took it off charge and went to sleep. At 530am I woke and checked the phone to check the time. The battery was at 15% and in power saver mode.. Usually I get 1 day usage (6am to 6pm, with streaming music to my headphones at the gym and messaging throughout the day) and get home with 65% battery. This issue has come back again now that I am traveling abroad.
I reset the phone to factory yesterday and only installed webex teams and whatsapp. The issue persisted yesterday. At lunch, we spent around half an hour eating and the phone was screen off and on the table and the phone dropped from 65% to 55%. I decided to remove webex teams and reboot the phone. The battery remained at 53% for approx 2 hours. I thought eurika, webex teams is the culprit. But unfortunately last night the same battery drain issue occurred and I had to charge the phone again at 5am.
I dont know that the issue is occurring until it is occurring.
The battery usage shows no usage by apps during this issue, and same when I show all device usage - for example I'll have say webex teams using 1% and screen using 1% but the device has dropped 60% of battery and there is no indication of where.
I dont mind to install a custom rom but I have not done any custom installs on this phone at all at this point.
Also I never used NFC until a few months ago for the banking app which I used to have. I just realised NFC was on yesterday and I've just switched it off. I just wont know if this helps until later today when the battery is dropping quickly. Although it just dropped 2% while typing this so I dont think it has helped. I just turned on data saver and battery saver and will see.
I am at a bit of a loss - has anyone else had this problem and found the culprit or a fix?
Update - battery saver and data saver does not stop the battery drain. 2% drop in 20 minutes with phone on the desk with screen off.
I decided to give up, re-install webex teams and go for breakfast; while leaving nfc off, battery saver on and data saver on. At breakfast, the battery did not drop at all. Uptime is 9 hours 50 minutes (cant remember if I rebooted before breakfast) So almost 10 hours later and I have been using the phone over wifi on occasions and a few phone calls and whatsapp. The battery level is now 55% so it appears that the issue has gone away at the moment.
It's driving me nuts as I cannot work out a trigger. It almost seems like something within the android system is doing something and it's being hidden from the systems battery usage calculation. 3rd party apps also do not show any battery drain but the battery drains. If the battery was faulty then I would expect this issue to not get fixed after reboot (or even by itself). I have reset the phone 2 or 3 times now and the issue is still present afterwards.
Tried to google for answers and didnt really find anything apart from one guy saying his phone was draining and getting hot at the same time. Mine does not get hot.
I suspected malware or something like that but I dont see how it can be possible that malware is there after factory reset.
OK I think I have made some progress - although can't be sure because this issue does go away and then comes back! However, this time I am refusing to reboot my phone so I can work on it. I am flying back tomorrow at 4am and so I need battery to last as long as possible. I have installed all of my important apps that I need to use. Given the issue is there when I have only 2 apps, the issue cannot be related to the apps I removed so I installed all of the important ones.
What I have done now:
1. turned off dark mode
2. opened the app permissions for the "google" app and changed the location permission from "always" to "only while using the app".
GPS Location is always off unless I am using google maps anyway but it did not stop battery drain previously!
As soon as I changed the permission app for point 2 above, the severe battery drain stopped. Take a look at the screenshot. You can see the severe drain on the left of the graph. Then the very severe drain was when I Was actively using the phone during the issue. Then I charged the phone. Then I changed the permission and you can see the graph have a flat horizontal line which is showing next to zero battery drain! I do not have battery saver or data saver turned on anymore. And I have been using the phone a fair amount.
Touch wood and fingers crossed. May be this will also stop google from emailing me every month with a google map breadcrumb trail of where I have been going.
EDIT - uptime of the phone is 28 hours and counting. Although you can see the charging points in the screenshot.
I have the same issue. My battery was just recently replaced too. I'm going to try the suggestions in your latter posts and see if anything improves.
Hey fourm, sorry for the long read but if anyone is technically savvy with batteries or voltages/electrical components please read! this might not be specific to a Fold but any device may suffer from what my device is suffering from.
I have recently had issues with my Galaxy Fold Z2 and it unexpectedly dropping to 0% charge, the first time this happened yesterday i was in an application and was switching from the larger display into the smaller one, upon closing the display the phone shut down and i wasn't able to get anylife out of the phone except a vibration when holding the power button, but nothing on the screen. I had about 35% battery at the time but all of a sudden it was at 0, after putting it on the charger it spring back into life. Today however i experienced an even worse problem... My battery was around 55% and i was connecting my phone to my cars bluetooth and importing contacts to the cars console, suddenly the battery went from 55% down to 9% instantly! i was shocked and took a screenshot of the battery graph showing its gradual decline from 100% to 55% but not to 9% to highlight the sudden drop, the battery status on the top of the notification bar was showing 9% all of a sudden but the graph wasnt just to actually see the drop! after that drop in battery it only took about a 30 seconds for that 9% of battery to jump down to 1% again in an instant fashion, following this only a few seconds later it shut down.I was thinking it could just be a dodgy battery for whatever reason but after trying to charge my phone after this sudden crash from 55%-9%-Flat i was unable to charge it up. The phone would signify that it was charging but not giving me a percentage, it would show the charging animation (the animation you get when phone is off and charging) but would only last for around 3-5 seconds before shutting off again and showing the charging icon again, and then shutting off again and rinse and repeat on a loop without charging but attempting too and resetting every few seconds! So for about an hour i couldnt get it to boot/charger properly and i almost gave up, but i decided to try a different charger, i was using the 25w supplied charger but i switched to a 15w older one and the phone ran the charge animation again however this time it identified the battery was charged at 55% rather that it not showing any charge level and resetting and trying again as it did before, this time it went right to 55% and from here the phone booted up and is working normally again!
Im really not sure whats wrong, im starting a process to send the phone back but i really wish to know whats wrong with my device! if anyone has any clue to this strange behaviour please let me know!
