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!

So I've had my Samsung Galaxy S 4G for over a year now. Rooted it many times with no issues. Until recently, my phone's battery meter seems to be messed up. Sometimes when I charge it to 100%, I use it for maybe an hour and it reaches up to 60%. Then, it randomly shuts off as if the battery is dead. I reboot it and it tells me to Connect my charger because the battery is 0% which is weird because it just said it was 60%. It shuts off again immediately and I wait for like 10 minutes later, then reboot it, only to see it say I have 40%ish left. I have already used Battery Calibration because it has worked in the past but now something seems to be wrong. I even use the Doubletwist Music app and it seems to be draining my battery life significantly more than usual as well (1 hour would take up about 25% of my battery) and the random shut-off because of "low battery" life occurs. Is this a battery problem ?
Try the one click gremlin remover, or flash another ROM. You can also try wiping cache, dalvik, and battery stats if you haven't. If the problem persists then you're probably looking at a bad battery.
Check your battery physically, if is bloated/swollen, then it is defective and needs replacement. but if not, then try going back to stock GB and see if the problem persists.
Take it out, put it on a flat smooth surface. Spin it on both sides. If at least 1 side spins like more than one or two circles, it's broken.
Thanks guys. I never thought a battery would get bloated but when I took it out, I immediately noticed this and haha in regards to the post on top, I thought you were only joking but you were right ! Anyways, I just ordered the same model number of the battery on Amazon (http://www.amazon.com/gp/product/B0...ils?ie=UTF8&me=&qid=1348188495&seller=&sr=1-1), in hopes that my battery life is back to normal !
Just a note, any recommendations/advice/tips on what you should/shouldn't do in terms of charging a battery. What I usually do is charge my phone every night and unplug it once I wake up. Maybe that contributed to the bloating.
Heat and deep discharge kill Li ion batteries, so your approach is good. Topping it off during the day won't hurt either.

I got a new bat last year and it's already puffy.
I guess that's why I am having worse battery on CM9 then already reported.
Yeah when the battery is bloated around the middle it means you need a new one. Battery life is not that bad on cm9 with a new battery. The old batteries thats been through a billion flashes and possibly overclocking with overheating and cooling are bound to suffer on cm9. Anyways their cheap on Amazon like $7 bucks for OEM.
I am prob gonna get a new extended slim one.
So, I have a Verizon Samsung Galaxy S 3 that I got around the time they first came out. It's never gotten wet or really had any problems until the past few months. The first thing that happened was the power button broke and it was stuck down for quite a while before I figured out how to "fix" that. A little carefully applied WD-40 around the power button did the trick. I got a new battery and everything seemed fine.
Lately, however, the charging is not working correctly at all. I'm using the same charger that came with the phone and it will seem to work fine most of the time, but it has problems once unplugged. For example, I'll charge it overnight and wake up to it being at 50-80% battery. Other times, I'll charge it overnight, it will then show 100%, but after unplugging it, it will very quickly, like a few minutes, drop to the ~85%. What happened today though was the final straw. I turned it off and let it charge for about 4 hours until it said it was full. I then took the battery out for 5 minutes before putting it back in and plugging it in again. It then said it was at ~15% battery. I turned it on and, yes, 13% after ~4 hours of charging. I still occasionally have problems with the power button getting stuck and causing a rapid discharge, but I can fix that now and I carry two batteries usually. Not being to charge them though isn't going to work.
I currently live in Taiwan and use Chunghwa Telecom. I constantly have a little notification that says "This SIM card is from an unknown source", but I didn't have problems until months after moving here.
Any thoughts on what could be causing the charging to malfunction and how to fix it? I love my phone and would hate to part with it.
Recently had to replace battery.
Phone was shutting almost immediately after it was disconnected from charger. Charging status when not switched on showed the battery kinda going in reverse. Phone was really odd as it would suggest the battery had 100% charge and then within minutes of disconnecting it was shutting down.
I tried a factory reset/refresh with no change. So I ordered a Genuine replacement battery off flea bay and installed that last Thursday.
Initially phone seemed ok, then wen a bit weird and shut down even though charge was like at 70% or so. Wouldn't restart until plugged in and then in shutdown mode the battery/charging indicator would show 0% and then very quickly showed 70%. Good bit though was it was going up and not down like before.
Fully charged phone overnight. It then seemed really good and lasted until Tuesday with 66% charge still showing. I had not installed FB or Twitter which made a huge difference. Then yesterday it just shutdown again. When plugged in showed 0%, within minutes back to 70% and then charged to 100% in the space of an hour or so.
So I am looking for any advice. Is this just calibration issues that the phone needs to get past. Is it possible the phone has corruption int he ROM.
I appreciate it might be a hardware fault but seems weird that the replacement battery is clearly showing a big improvement suggesting battery was EOL after 2 years use.
TIA

Same problem here i will try to install the oficial rom of xt890 if works i back here if not i don't know what to do
Sooo............issue is still present. Odd thing which I am unable to confirm, due to rnadomness of shutdowns, it that I think it is slowly learning the state of the battery as it originally was shutting down at 70% after 2-3 days on standby. then 66% hen 56%. I did a clear cache partition and a fresh install but still the issue was present.
Clearly the new battery is lasting longer than the old one, just the phone does not seem to know to reduce the charge indicator all the way to 0%.
Anyone any idea why this might be happening.
TIA

Just to add i'm having the same problem.
Symptoms started last week running the stock kitkat rom so i ordered and a fitted a new battery. Initially everything looked good phone said 100% left it over night and noticed it had shut off when i came back to it. Plugged it in to the charger and it said 0% so i charged back to 100%, booted up android and almost immediately it begins discharging rapidly, i would say within 15 minutes its back down to 0%.. I've done this a few times now even left it on charge overnight for 8 hours but its still discharging rapidly everytime. The craziest thing is even if it says 0% in android i can still boot in to recovery and flash away so clearly there is charge in the battery its just android thats out of sync.
What i've tried so far:
Different wall chargers/USB leads/Outlets
Wiped everything in TWRP and flashed CM11
Factory Reset several times
Various battery calibration apps
My next step is going to be trying RSD to flash the stock ROM but beyond that i dont know what to do.
I'm experiencing EXACTLY THE SAME ISSUE with my Razr i, replaced the battery and it's still discharging very fast
Eventually managed to resolve my new battery issue simply by fully charging and discharging several times. It started to hold charge after the 7th charge and after several more discharges it's now up to full capacity.
Hey guys, As title says, So the story on this thing lol Bought it new I believe 1.5-2 years ago, battery got bad, so this spring in february I replaced the battery my self, I had ordered 2, Both certainly a genuine battery, I had a S7 so I wanted a spare for mine when IT came time. After battery replacement phone was great again, good as new! then as of 3 days ago random shut offs. battery reads 80% shut off, Then I noticed If I left it off for a few hours or all night and turn it on in the am 0%! Tried charging and It's not taking a charge really, It went to 9% and stayed there for ever and was getting hot so I didn't want to risk it. ok so bad battery, this morning I swapped in my OTHER spare new battery, and Let it run up to 100% before turning on for first time, All seemed good! then all the sudden after 6 hours (before it was like every 10 minutes it'd shut off.) It started doing it again, Same thing battery is dead it figures, But it can't be.
Thinking perhaps the board it's self or something just ain't right? :\ Any thing to check or tips/tricks? I tried googling and came up empty handed.

It's likely the batteries you have are not genuine. Fake copies don't have a control chip which interfaces with the device. Your phone is shutting down to protect itself from overheating and other problems caused by copies.
There are some great copies out there but trust me they're still copies.

Yeah that's for sure on the copies, I had looked at how to compare what I had VS the fake ones and they seemed to be genuine? The batteries came from 2 seperate sources as well so hard to say, if the first one I put in was a copy then it did last a while but surprised then that my 2nd one never made it more than a few hours and the same issue. But you just never know. Everybody claims your buying a genuine battery but I'd assume the listing prices are tell tale of a fake/copy lol
Monitoring the battery and either the voltage sensor is bad or the battery, it'll chwrge and say it's full but yet voltage goes to 3.4v, then if I plug it in again it'll go up to 4.2v, once I unplug it, it drops of course, I was using a battery burn program and Itll drop from r. 2 to 3.4 right away, I got it to run for 15 mins one time then it dropped off, otherwise another time from 4.2v it dropped to 3.0 then shut off after starting th test in like 20 seconds, reports battery immediately as 17% after re booting.
This battery sat for a while so will try a 3rd fresh battery and hopefully genuine, though I suspect my past 2 were genuine.
Wanted to update this for anybody who may find this thread off google. I got the same replacement battery again Which was the fix, Asked the seller and they said they'd shoot me a new battery, Again whether genuine or not... Well they claim genuine. I let the phone charge to full and Performed the battery draw test by running the 2 apps to bog the phone down and make everything run to 100%. ran like that 0 issues for about 2 hours, Voltage was very stable the whole way through, before It would maybe hold for a few mins then shoot right down from 4.0 to ~3.2V. Even now after a hour It was still well above 3.7V. My old s7 battery was exactly that, sat unused on my shelf for ~2 years because it was mis-placed and even installed it was no good either.
I have a lot of trouble with the battery on my S7. Shortly after updating to LOS 18.1, it started behaving very strangely. The battery degradation happened over a couple of weeks, so it rapidly got worse.
At the beginning it shut down at anywhere between 15 and 20 percent, most of the time with the 15% warning. It got worse over time, then at some point it switched to being stuck at 80+ percent for almost the whole day, draining very little battery and then it just went black in the evening, like if the battery was pulled out.
I started slow charging the battery, which made things a bit better again. Now the percentage seems to be somewhat accurate again, but battery is draining so fast, I have to charge it twice a day to keep it running. It even drains battery while off, like yesterday I turned it off at 35% and this morning I couldn't even turn it on. Sometimes it also jumps from 100% to 60% after a reboot.
I made a backup and tried resetting the system, which didn't work, same behaviour. I could try to go back to stock, but as it also drains battery while off, I'm not too confident that it will actually make a difference.
As I have another disassembled S7 still in my repair drawer, I could try to change the battery, but my glass is a bit shattered at the bottom of the touch screen, so I'm afraid I'll completely break it this way.
I don't think there is much I can actually do, but I wanted to ask you people for any advice.
Edit: I have successfully transplanted the battery from my other S7 and it works great again. No battery problems at all, so the culprit was a faulty battery.
