Hi All, my wifes s6 (using xtrestolite rom) has stopped taking a charge. Im trying to figure out what the issue is. Unfortunately im travelling for the next month so have limited trouble shooting options.
Background
- wife has been complaining that her phone battery dies quickly. I kind of dimissed her assuming it was in her head. she said it loses 10percent in standby mode in 1hr roughly. Shes been complaining about this for a week.
- yesterday at the airport her battery was at 12% and when we plugged it in to charge it wouldnt take a charge. Bolt icon did not come up and still said "connect charger" on the screen. Normally when connected the red Led comes on, but now it doesnt.
-our normal chsrging method is using and aukey 3port charger as fast charging mode.
Troubleshooting/diagnosis
- i have an s6 as well so i tested all the cables and chargers on my phone and it works. We even had the official samsung charger and cable but same issue.
- after the phone was completely dead, if you plug in the charging cable the charging bolt icon comes on for a few sec, the top left says "kernel is on seandroid enforcing" for a sec and then everything goes blank. Red charging led doesnt come on. So it seems like it detects the cable but wont charge enough to boot up.
- i was able to boot into twrp recovery but where its supposed to have a battery level its completely blank. Originally i was able to do this without any canles but then it wouldnt. My guess is that i orginally had a bit of juice and then it was completely dead.
-after leaving it plugged in for a sec, im able to turn it on where it boots and i can see it says 0% battery. It stays on for 5sec before turning off itself.
- i also tried plugging it into laptop, but laptop does not detect it. The phone does detect the power though and does the same as above but this time bolt charging icon stayes on for 1-2min before going off and seeing the "kernel is on seandroid icon". Once the seanadroid goes away nothing seems to happen. After doing this i was able to turn it on and it showed 1%. I thought this was promising but after trying this a few times ive never been able to get to 1percent again.
- with the brief charge thst i guess its getting, i was able to go i to twrp recovery and do a factory reset. This was with cable plugged in the whole time. Without cable in i dont think it would complete the action.
That about summarizes whats happened.
Ive concluded the following:
- charger and cables are ok and not the issue
- it is not the charging port since the phone does seem to be getting some juice bacause charging icon comes on for 2sec whenever cable is plugged in.
- its not a software/app issue since it wont charge even in recovery mode. Also factory reset was done and no luck.
My best guess is that the battery can only hold a 0-1% charge which is enough to register it being plugged in but not enough to do anything else. But if everything else is ok shouldnt it work when if the cable is just left in. This makes me think theres something else going on.
Any suggestions or theories would be much appreciated trying to decide if i should pay to get battery replaced.
Sorry for the long post. Figured it is best to give all info.
Thanks in advance!
Update June 3:
Hey everyone, just a correction on the above. It looks like it is able to charge in recovery (slowly). I realized that although there is no battery level during recovery, no charging led, and not booting up after being charged for a bit, maybe its just going slowly.
So i went into recovery and left it overnight on the non-fast charging and woke up after 8hrs and it was at 78percent!!!
Im not sure why it didnt go to 100% in 8hrs.
The phone still doesnt charge regularly when plugged in, so still need to fix that.
Do you guys think its a rom issue (only factory reset done before) ? I will see if i can get a rom for flashing.
Update 2:
Reflashed xtrestolite rom but still no luck. It wont charge.
Seems like a dead battery.

Bump.
Went to the phone store and they said its probably not the battery but the ic chip for charging? This will cost 150, but doesnt include the screen if they break it...
Does this make sense since i can charge in recovery.
Thanks. Any direction or input is much appreciated.
Go on the local store and change your battery (if isn't in warranty)
Hi all, just wanted to update the post that the issue is semi-fixed.
I brought it into a repair shop who offered to diagnose the problem for free before paying to replace the battery.
He told me there was nothing wrong with it and not sure what my issue was. Plugs in the charger and lo and behold it was charging. He said he didnt do anytning to it except blow some compressed air on the port.
Im guessing the comporessed air cleaned out a short? So now it charges properly.
The issue remaining is that the pc doesnt detect the phone. It shows as charging on the phone but no conmection. Tried to install the latest samung driver (1.5.4xxx?) but no luck. On occation sometimes it says "usb port has malfunctioned" but other times nothing.
My s6 does actually connect, so definitely my wife's s6 itself and not comp. Im tempted to buy some comlressed air and give it ankther blow, but dont want to risk messing it up again. im pretty happy that it at least charges up.
Hope this helps others that might have similar issue.

I was away from home for 2 days and forgot my charger. Naturally the battery died.
I came home and charged the phone (plugged in the USB cable), left it for an hour or so and tried to turn it on. I got a "spinning" black and white wheel (which is actually frozen). Next comes the grey image of an empty battery which doesnt show charging (filling with green) even when the phone is plugged in. The home, back, etc. etc. buttons flash white for a moment and the phone turns off. Try again, same thing.
I thought maybe the USB wast connecting or charging so i took the battery out and charged it on an external charger which shows that it is full. Put it in, same thing.
Tried hard reset but cant complete it because samsung logo screen doesnt come on, only "empty battery" image.
Phone doesnt show up on my mac. etc. etc.
I am out of ideas...
btw no kind of water contact or dropping.
I really hope someone has another suggestion or can point me in the right direction.
Thanks for reading.
oops didnt read full post
Try going to att and use a charged battery there. Your battery may just be dead from over discharging.

thanks. i plugged it in and will let it sit for a while. i did try to turn it on as soon as i plugged it in and still saw the battery which didnt appear to be charging, but i know from previous experiance that when a phone is really dead the battery wont start it immediately even when plugged in.
thanks for the advice. my fingers are crossed
edit: ok. i'll try that also. if i can get away with just replacing the battery thats fine
this happened to me several times as well. My fix was easy.
Plug it in and forget about it for an hour. Unplug it, power it up, plug back in as soon as you see it start to boot. Should boot and charge.
I don't know why, but when its DEAD dead DEAD, it won't boot while its plugged in, nor will it show charging.
I hope that helps!
hopeful...

Thank you for the advice. I am happy to know someones dealt with this before and I am not the only one.
I just want to be sure. When you say that it starts to boot up, do you mean the samsung logo or the b/w wheel with empty (grey) battery image?
I tried to plug in the USB when the empty batt. was showing but it didnt seem to respond. Also I am wondering, when it finally connects do you still just let it charge or do you fully boot it up? Also does the battery show that it was keeping a charge from the first hour you left idle or does it only start to keep the charge after youve done this process?
Sorry for all the questions. This is just a bit for me....
update: OMG! just plugged it and instead of an empty batt. it was 90% green! phone still shut off again but i am very hopeful something is going on. I am going to keep messing around
update2: thank you so so much. This finally worked. saved me a considerable amount of money and untold grief. Basically I followed your directions in hyper mode. Power on, USB (in/out/in/out/in/out), phone shuts off, immediately power on again, etc., etc., until it worked.
Thank you.
FYI, a proper charger (instead of a PC's USB port) will cause the device to go into a higher-current charging mode that MIGHT have behaved better.
You can only charge your phone when its off on stock. Being in a rom it will reboot hence your frozen spinner and grey battery. Try it now that your battery is fully charged a d it will just reboot.

just had the same problem tonight, but when I pulled out the battery it had a fried electronics smell in the battery
Same thing happened to me driving home from Thanksgiving break. I've come to the conclusion that if you flash a non Samsung from then you have to have the infuse on to charge. Even with a dead battery I managed to get the infuse on, then immediately shut the screen off for about 30 sec before proceeding to quickly turn setcpu into power save mode before shutting screen off and leaving it off for a few hours. Should veeerryyy slowly but surely charge (stupid samsung ..... takes forever to charge and there are times when the battery goes down in heavy CPU apps or when on 4g, I noe its safer that way but its not like I'm going to have that phone for the next 5 years)

So glad I found this. My wife's "Infused" Infuse was "acting weird" according to her. Said there was a weird "DOS" like screen for a second, then the dead/grey battery logo. Take bat out and put back in. Nothing. Plug in and start up and it either goes from the Samsung logo to off, and repeat that, or show the Dead/Grey battery thing again. Well, tried the turn on while unplugged, and immediately plug in, and it started up. Even said the batt was 96% charged! Really confusing. So are there any other ROMs usable on this thing? Infused is OK, but man, just not nearly as good as my N1 running CM7.
Thanx again for the tip!

everything in development is.... obviously. Also, do make sure your read everything first lol it can really help you and other people at the end.
I got the infuse for me and the wife in early December. After the initial charge she used hers for about a day and half then tried to charge it.
Nada.
Tried different USB cables, swapped batteries. Turned out the USB port died. Talk about a PIA!!!
Best buy swapped it out no problem and let me keep all the stuff in the old box.
Got an Infuse 4G from my neighbor ( He switched from ATT to Verizon knew I needed a phone so he was kind enough to give it to me) and now the phone doesn't charge. What can I do?
Chances are, you have a bad charger or a bad battery.
Either that or a broken usb port. You could be surprise on how many galaxy phones get no charge because of the usb charging port. Its very sensitive and it can be broken quite easily. But if you give more details maybe we can help. Does it responds when you connect it or it wont do anything at all?

can you plug into the computer and it stays connected with no issues or problems...if yes, then your port on the phone should be good
batteries do have a life span...and they are cheap on ebay...I got 2 2000 with charge for less than $20 bucks...great deal
prob is your battery if you wanna stay oem battery same thing you can get them at good prices on eBay and Amazon

Infuse Wont stay on or charge
Hello, maybe someone can help me here. My infuse suddenly won't charge or turn on at all. When I plug in the USB cable from my computer or the wall the battery icon comes on with the animated loading circle thing then goes off after about a second of doing that. When I do a hard reset with or without the battery in it and with or without the charger plugged in, the same thing happens.
Its been several days since this has been happening and after trying again today, it actually turned on and booted to the OS and was charging for about 5 mins before it stopped recognizing the charger. I pulled the battery and it since will not turn on. The battery has some charge on it but will not turn the phone on, just does the weird battery thing as described above.
I have tried several different charging cables, but have no other battery to try. Any suggestions?
Hello i had the same problem awhile back. When my phone was not rooted(Infuse) i had to go to recovery mode and wipe cache after that the charger recognized right away on the phone.
Another time After i rooted i flashed a bad rom and i could not get my phone to charge while it was off. It could only charge with the phone on....SO maybe try flashing a newer better ROM i recommend CM10.
Another thing i had to do was switch this old charger i had it would recognize for 5 min then Stop. It was just a bad wire connection.

The problem is I cannot get it to turn on at all. I was running CM10 and have tried 4 different charger/usb cables.
Sadly, the connection of this device is a known weak spot.. if its not doing anything when connected to some form of current.. all signs point to a dead port..
Hopefully that isn't the case..

I also went through this issue and i discovered that it will keep going through a battery icon and then off loop so the way to deal with this is as soon as you see the battery picture just hold the power button for like 2 or 3 seconds and then you should see the battery green indicator with the botton dots animation and it will Charge.
I am having the same issue as xtz as well. I cant get it to turn on. I flashed the Paranoid Android rom and it all went downhill from there. I flashed it and it had 10% battery left, by the end of the night it was at 1%. I went to bed and woke up with it only at 5%. I went back to stock then re-rooted it. I installed CWM but it wouldn't let me go into CWM recovery, only the Android recovery. Now the phone won't turn on at all, I have swapped batteries and USB cords with no luck. This is a brand new unit less than a week old, the battery is also less than 2 weeks old. Any help here? It won't turn on at all It does the same little ritual that xtz's does.

I had the same thing with mine when I first got it (used), I plugged it into the wall with a 2amp charger, left it overnight, and in the morning it was on and charged.

I already tried that and it seems to have messed up one of the batteries. The little loading circle will come on for a split second then it will go away, come back a few seconds later and it just loops. I plugged in the USB while holding the volume keys to try and get it into download mode but I'll get a warning message saying something about installing a different OS being dangerous, again, for a split second, and shuts off. It seems like the phone can't have any power go through it for more than a split second.
I'm having a similar issue with the phone not charging. But the phone won't PC or wall charger. But check this out I have a jigg for putting device in download mode when I connect it to phone. The phones goes in to download now when powered on. So what do guys think is wrong?

From the info you provided: the phone is not charging but the jig works.
Do I need a new battery or does it sound like the USB port shot?
Same thing happened to my daughters galaxy s2. Usb port is shot. I got her a battery wall charger and a couple spare batteries. Charged the battery, popped it in and turned right on.

Thanks for the helpful information.
Ok so I plugged my phone in last night and charged it like normal. Woke up everything was good full charge and ready to roll. Worked my lunch and dinner shift at work, got home went to plug it in and got the slow charge message. No biggie have gotten that before adjusted my charger and boom nothing no charging at all. Changed chargers, and nothing. Completely factory reset back to stock d801G via kdz which means my port is good because I can access download and flash new firmware. Its currently plugged into my computer screen lit up with charging logo, and the led lit up too, but no real evidence that charging is happening. Any ideas on whats going on with the phone? Any ideas on fixing it if it isn't actually charging?
Let me lay down the story first:
It all started when I tried out multiROM for the LG G3. I was running cm12 perfectly fine, unlocked and everything. Amazing battery life. But MultiROM barely worked, even though I followed the instructions exactly, I had many errors trying to get anything to boot properly. I got help with it, but ended up getting rid of multirom via internal storage (where it was) and flashing a normal, non modified TWRP 2.8.4.0. This is where stuff starts getting weird.
After getting rid of multiROM and flashing cm12 again from backup, I noticed my phone wouldn't take a charge at all. It was booted up and running at about 30% battery. My PC wouldnt do anything when I plugged it into my computer, too. I thought it was just Cyan being weird, so I rebooted into twrp and tried plugging in. No buzz, still wouldn't take a charge. For some reason, turning the phone off and plugging in the charger while it was off actually turned it on. So the charging port has to be working, the phones just being weird... but then I decided to smell the charging port. Smells like pure burning electronics. I rebooted the phone with the cable plugged in, and it boots up and charges. This is odd, because i can no longer plug the cable in while the phone is on, i have to reboot it with the cable in now in order to get it to charge. I tried flashing back to stock ROM, and same exact issue happens. Not only that, but the battery no longer holds a charge for more than a day on one full charge. It lasts about 3-4 hours now.
Please, xdaers, help a brotha out. I'm really pissed about whatever the hell is happening to my G3. It still works fine, I just have to reboot it with the cable in in order to get it to charge at all and the battery life sucks on top of that.
Note: One time after all this happened, the phone died fully. Plugging the charger in, the battery logo was flashing on and off. I tried multiple cables and chargers with the same problem. I pulled out the battery with the cable still in, and the battery logo actually stayed on the screen and once I put the battery back in, it charged again. THIS IS MAJORLY CONFUSING and hard to explain so I will clarify my issue if you are confused with my post.
Also, the phone likes to get really hot and die fast by itself even without the charger plugged in now.
thanks guys

Good luck!
So you flashtooled back to stock? And still persists? If so you next option is to buy both a battery and a charging port and do some trouble shooting.

Don't know about the charging port, but as far as battery life I'm getting the same thing, except mine lasts about 2 hours, I've decided I'm selling the phone while its still worth a bit of money, probably getting a Note 2 or Xperia Z2, I've been very unhappy with this phone, also my battery cover is falling apart and cracking,

I get 13+ hours with 4 to 5 hours screen on time and 1to 2 hours of talk time. So I don't think your battery issue is normal for this phone. You have either a defective battery or phone or an app that is misbehaving.
I'm having the exact same problem with LG G3.
Can only charge when rebooted. And even then the charge indicator does not show charging.
I have to go into setting->battery where it shows 'charging'
I have tried new battery and cleaning port.
Anyone figure this out...?
My battery drained very fast before too after backed up to stock, but after I upgraded to 5.0, my phone can lives up to next morning!

Hello,
I went out last Friday and came home late. My phone is out of battery and dead. I plugged it in and woke up the next day with a dead phone. Apparently, there is a bug with the OPO. If the battery is too low, it won't even charge after you plug it in for charging. I have tried all tricks and even contact the OPO Tech Support Team. This thread describes how horrible they are:
http://forum.xda-developers.com/oneplus-one/general/tech-support-onepluse-one-horrible-t3084022
I am at my wit's end. I have tried all the the tricks. This is a thread that I found that seems to have the same problem as I have.
http://forum.xda-developers.com/oneplus-one/help/oneplusone-phone-dead-t3079256
The only choice I have left is to open the phone, disconnect the battery connection and reconnection it again. Hoping it will recharge. However, there is a warranty sticker and I don't want OPO to deny my warranty. I am not new to Android and I have fixed phones before. I also think of buying a new OPO battery and switch it with the factory one. Since the new battery will be charged, I think that will work in fixing it. But, doing that is much more complicate and it requires me to remove more components. If you have a good working solution for my problem, please help.
NOTE: please don't ask me to check my charger or use a different one. I check it 1000 times already. The original charger works, the cable works. I use different chargers and cables. Same result.
Thank you for your help.
Have you rooted and unlocked? I had the same problem when I got mine at first. It would show charging but never fully charge. 73% was all it would do. So after rooting and flashing a custom kernel the problem went away. Now I can go back to stock and the problem has never comeback. Maybe just a small software glitch or something. I'm just happy it's gone!

The phone is unlocked and rooted. The issue is not fully charged or not. The issue here is the phone does not charge after the battery die. The phone is dead because I let the battery run to 0. When I plug it to recharge, the low battery screen does not even come up. The phone is dead and refuse to recharge. There is no issue with the charger or the charging cable. I have checked it several time already. I am very frustrated with OPO Tech Support right now.
I see. Only other thing I can think of is try holding the power button for 60 seconds while it's plugged in. That does suck man.
I had similar issue, my conclusion is the bootloader charging function is broken.
Basically I would start the charging, it would charge for about 10 seconds or so, and then stop. I thought my battery was dead.
I couldnt boot the os as wasnt enough charge.
So eventually I just kept repeating the process, 10 seconds charge at a time, and eventually had enough juice to boot android and after that point it charged to full ok.
Never had this issue on any of my samsung phones.
Also to point out when it went dead it was plugged into my pc usb at the time with twrp loaded.
