Few days ago my battery went completely empty (0%) and the phone (LG Optimus 4x HD) turned off. I barely managed to turn it on again: every time I'd turned it on, it would display garbled screen, usually green or purple. I left it on charger during night, and it finally started. Same thing happened yesterday, but now the problem is that battery wont charge. This morning it was ~50%, I try to start it, but it caught a boot loop (known problem of the rom I'm using) and as I restarted it in TWRP, battery was on 2%. I put it on charger again, but it seems like battery is discharging! Now it's on 0% again! Also, last night when room was quiet I could hear high pitched noises and squeaking sounds from a CPU, and phone was hot. Is it normal for cpu to work when phone is turned off but charger plugged in? Now I don't know what to do, I left it charging again. If someone had similar situation, please help. Is my battery dying or this is a hardware failure?
Hi there,
I'm pretty sure that your battery is damaged. Try other one and see if something changed.

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!
Hey folks,
I'm sitting here with a very stylish paperweight. Can't charge it. No LED, not even the blinking red one. Just nothing.
Here is what happened:
My phone started to get pretty hot, so I decided to turn it off, just for safety. It had around 90% battery left at this time. When I turned it back on an hour later, the battery percentage was at about 18-19%. I used the phone as usual. No strange behavior, no sign of malfunction. After using it for quite a bit, the phone shut down as expected. The battery percentage fell in an usual matter. It went off normally.
Now, when I try to charge it, it doesn't seem to show any vital signs.
Here is what I tried:
- charging it for 2 hours with HTC Wallcharger, also tried out 2 other chargers
- Power + VOL UP
- Power + VOL DOWN
- both with a bright light pointed at the sensor
Still nothing. Connecting it to PC won't do anything good atm.
Is the battery dead, or is it just terribly drained? Did I even manage to fry the MB? Is there anything I could do?
Turning it in for warranty repair won't be an option, since it's (you guessed it) rooted and therefore unlocked. I flashed CM11 nightly about a week ago, had Codename Lungo before.
This is quite a bummer. I hope, you good people might be able to help me.
Thanks in advance,

Hi there. Ive looked all over the net to figure out this problem i have with a samsung i9505.
Phone appears to be running fine . My concern is when i charge the phone it seems to charge properly, but when it gets to %100 it just keeps going going and more going for hrs and the green light wont come on saying its finished charging remove the charger. Ive done resets updated to lolipop tried different chargers and battery.
It red light just stays on at %100 with the battery charging icon still saying its charging
Turn the phone off and plugged the charger in and it juzt sits on %99
Im fairly sure its probly not charging but just wondering why it wont say green light finishef charging please remove charger
Any ideas?
After last night i tried something, it was sitting on %100 for ages showing its charging, so went to bed with it on and it took like 5 hrs for it to go green. im thinking yay
But no, i wiped the cache did a full reset and even in aeroplane mode with everything off and nothing installed after the reset the battery is still going down really fast in standby mode like %10 per hr..
Seems like the phone hasnt got the right info about the battery or something its just all haywire

Hello everyone,
I've bought an used Z3 dual couple days ago,and after having it for some days now I noticed that the battery jumps around,for example from 88% to 50% then 32% then goes back to 88%..
That usually happens when I'm running heavy apps,like camera which caused a phone overheating as far as I noticed.
Anyways,Yestrday I fully charged the phone and when I plug it from the charger it does down to 50%,it stayed at that level for almost 24hours.Few hours ago the phone suddenly the phone turn off (while the battery was still 50%).But After putting the phone in the charger,the phone keep showing "charging icon" and turning off.It was like this for 30min and it is not charging at all..
Have anyone been in the same situation before ? What could be the problem ? and how would I solve it ?
Waiting your kind replies..
That sounds like the phone battery is literally dying.
Don't think that it is a software problem you could solve on your own.
You could try this though, doesn't hurt if you do the Method 1:

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!
