try leaving it on the charger a while... but I'm sorry to say that it sounds like a brick. If it won't take a charge, you won't be able to odin anything. I had a similar issue and the battery would get real hot on the charger but it wouldn't charge so I couldn't flash anything.
good luck my friend

I'm hoping its not a brick, i left it on the charger and was getting warm. This sucks how did it even brick

guys help me.

what the hell do you want help with? Find a way to way to charge your battery and Odin something.

Need more details than "my battery died".
Are you rooted, what rom, kernel and recovery? What did you do leading up to this point? What have you done to try to remedy the problem?
Cover the basics and you might get an answer

There could be two possible problem
1.Battery is not charged - maybe usb cable is bad. Try charge with another cable
2.Battery is bad or dead - replace the battery.
To test couple of things, try to use different battery if you can find. If phone boots up, then you don't need to worry about the brick.

Yes I am rooted. My rom is MIJJz BLEND ICS 2.5 and Im using Rogue FC18. I was at work and texted my dad that I was off and at that time my battery was at 1%, well it died and ever since then it hasnt turned on. I have flashed anything since the 18th

If you were in my situation you'd be desperate for help

Im not sure if our phones are even capable of doing this but take out the battery and plug the charger into the phone without the battery essentially bypassing the battery. Its strange that the phone would just brick, it sounds like something more than that.

I tried that and it didnt work this sucks bro

Take out the SD Card if you have one. And I assume you have tried accessing the recovery menu while plugged in?

That was the first thing I did, I can get into Odin but it says my battery is to low

How long are you leaving it on the charger? I know with some devices like ipod touches and stuff if they are really dead they need to sit on the charger for a while so they can gain enough power to boot up. However I will say my epic has gone dead over night before too and when I plug it in it goes right on. I would definitely take it to a sprint store. Make sure they have a repair center though otherwise they will want to mail it to samsung and then you will be without a phone for at least a week or two.

I have had batteries/phones in the past where they would only accept trickle charge after they were fully drained. My theory is since these batteries take more current as they get more depleted, they are refusing to charge because the current is higher than expected.
I have no idea if that is what is happening here, but you may want to try low current charging sources .5 amp or less.

You can try an external battery charger....if you have one. If not, find an extra charger and strip the end. Take the battery out of the phone and put the bare wire ends on the appropriate terminals on the battery and reinsert it, now you will be directly charging the battery. Its not very safe if you dont know what your doing, but I have done it before....I actually have a charger set up for this. Another option would be to tape the wire ends to the terminals.

Ok so I just tried to boot without battery on my device while plugged into the wall. It doesnt power nor do any lights come on. I think it may be your battery brother. I would suggest order a cheap one off ebay and have it ship as fast as possible just to check it for a solution. Or go to your sprint store with the battery only and tell them that it is not working and that you want to replace it and see what they say.

Sounds like a bad battery to me. I would try what the guy above me suggested. Get a extra battery from Ebay. Or take it to Sprint..

This happened to me. It was a bad recovery/kernel.
Find a way to charge your battery, boot into download mode, Odin a stock ROM from sfhub and start over.

FIXED [Q] Gnex Charging issue

Hey all im having a charging issue with my gnex, It will fully charge, however the issue is when I unplug the phone it says that its still charging then it will say its discharging(like normal) however a few seconds later it does the same thing and keeps doing this until the battery hits about 85% then it will act normally. What bothers me the most is the screen will come on and stay on and im worried of LCD burns. I have odined to stock tried multiple different ROMs and Kernels and to no avail. Any help would be greatly appreciated. Thank you all in advance

Have you cleared the battery stats? Also try the EZ battery calibration app from play store that helped me tremdously good luck

Charging issue
I was having the issue with my Gnex. when i plugged it to the charger it would charger but when i unplugged it it will say that its charging. just like yours mine would fix itself. at first i though it was s/w so i factory reset and even flashed another rom or same rom. i did notice something this only happened when i plugged it to a certain charger which was a Samsung charger but not the original. i stop using that cable and never had the issue again

I can adore you that neither one helped you. You just so happened to fix the problem independently at about the same time. In a nutshell, you're equating correlation with causation.
Batterystats.bin has absolutely nothing to do with battery charge. The only info contained in that file is a list of apps that have operated on battery since the last full charge- nothing more. The file is automatically cleared each time you unplug the phone after a full charge. The wives' tale of that affecting battery charge or the reported charge level was officially debunked by a member of. Google's Android team early this year.
It is for this same reason that apps that claim to calibrate your battery are 100% snake oil.

It would seem that your USB port may be shorted or, less likely, you have a defective battery.

Had this same issue, had to get a replacement on my insurance =[

Clearing Batterystats.bin is a busted myth.

Ok so i fixed it (and it was rather simple too)
i plugged the phone into the wall and popped out the battery and left it plugged it for a min or two. then i unplugged it put the battery back in and let it show the charging then popped out the battery again then the usb. Put the battery back in and powered on and its working normally now.

[Q] Captivate Glide battery draining issue?

Within a second my Captivate Glide will suddenly go to 0% power then slowly charge back up over time..or if I charge it, it jumps back up to about where it left off. And it happens pretty much every time I turn my phone on for more then 5 mins. It seems to happen while sending or receiving text? Any ideas what could be causing this or a solution?
I keep my data off, and theres 3 apps (Stock SMS Messenger, Handcent SMS, and the Contacts+ App) that can handle SMS on my phone, and I have locker pro that displays my notifications. And I also use the Nova Launcher, but thats the only app's I keep running. Maybe a conflict with the apps or a bug with one of the apps? I don't see how that'd effect the battery that much but possibly?
I've also changed my ROM a few times, but right now I'm back on the newest ICS update and I've rooted it. Maybe I need to change it again? I can't remember if this problem started happening before I did my last change.
Or maybe just a bad battery? I don't know much about batteries but I haven't had this phone long, I don't think it'd be the battery.
If you have any more questions feel free to ask and I appreciate any help!

I had about the same problem, with it working fine with a decent charge (anywhere between 30-80%), and all of the sudden it would say "battery critically low" and shut down. Putting it on the charger would often get the charge to show what it was before it freaked out.
I noticed that the battery was starting to bulge and get somewhat "mushy"....which told me the battery was probably going to explode or leak if I didn't replace it soon
I have had the phone for a year and four days, and this just showed up in the last few days...fortunately I bought an extended warranty and they will pay for the replacement battery I just picked up today.
FYI, the battery should be totally flat on both sides. Mine would wobble if I set it on a table.

Ok, TL1170, Thanks!
I already narrowed it down to my battery by the time you posted that because I factory reset my phone multiple times and changed the ROM once to see if that'd help, and it didn't..I was running out of stuff to blame it on ..
But yeah, my battery is pretty badly deformed and I just ordered a new one.

Thanks, mine is doing the same thing - about once every 2 days or so. I can see in the battery life plot that it sometimes goes from 90% almost completely vertically to 0% and then right back up to 90%. I don't see any obvious bulges or "mushiness" to it, but it doesn't seem to be completely flat when put on a table. I'll see if I can get a replacement battery, this phone was not used by it's previous owner for maybe a year or so before I bought it, maybe that might have been part of the problem.

Any time a battery is misshaped it can do the oddest things.

Pull out and visually inspect your battery. If there are any visible cracks or bulges, dispose of it carefully. Damaged lithium ion batteries are incredibly dangerous; a properly pissed off LIon will produce a sizable fireball.
If your battery looks fine, fully charge it (until your phone says "100%" or "Charged"), then fully discharge it (don't connect to the charger again until your phone shuts off for lack of power). This is to calibrate the charge estimator chip in the battery itself. Don't bother with batterystats.bin, it's completely unrelated.
If the above doesn't work, you need a new battery. If the new battery behaves the same way, you need a new phone

Happening to us too
It's been happening to my phone for a while now, but I'm usually using it while at a desk so I can keep it charging. However, it just started happening to my wife's Captivate Glide also. I checked my battery and don't notice any bulging or non-flatness... but it happens about once or twice a day now - Pretty much anytime I do anything more than make a call with the battery indicator saying it's somewhere less than maybe 90% charged. I've taken to using a portable backup battery when I'm out.
If you view the battery usage screens, you can see the cliffs where it drops from 80-90% down to zero and right back up. We've only had them for about a year, so I'm going to take it to AT&T and see if they can do anything for it... probably not.

If you're really desperate to get those particular batteries working, you could try cleaning the contacts, both on the battery and in the phone, with rubbing alcohol and Q-tips. But most likely you will need new batteries.

Battery( low power) Shut Down Issue Fixed
I also was having the "critical powerl level" shut down issue over the past two weeks. My phone is about two years old, and there was a few occasions in the past two weeks where i pulled it out of my pocket and it was off. Then this past week the phone (on a full charge) would go anywhere from around 90% sometimes %40, and then all of a sudden say "battery low" and shut off. It would turn back on, but would only stay on for a few minutes.And a few times it also got really hot. It wasnt doing this when plugged into the wall so i examined my battery and there was NO visible flaws or bulging of any kind, it looked fine. But as we all know just because it looks good certainly doesnt mean it is so i odered one on ebay for about $10. It arrived 2-3 days later and instantly fixed my problem. The phone is fine now and hasnt done anything wierd. It was the battery. These batteries have a limited life span, and very often the phone may say the battery is 76% charged but the capacity of the battery under load can still draw it down to 0%. You cant always trust the level the phone says its at. So if anyone else out there is having this power issue it really isnt expensive to find a good battery out there. The one i got was $9.98 and it is a Samsung battery identical to the one that came with the phone. Except the new one has a fresh date of 2013 on it. Very happy to have my phone back. Ive never been a part of any sites like this, but im posting here now because there seems to be a lot of people having this issue, and often someone will put a very complex procedure on these sites to fix an issue when its not always necessary. If you have the power/shut off issue like i've described here and your phone does the same as mine was its probably the battery, and for the price of a new one like i got, its worth trying.

[Q] Heavy battery drain after SOD

Hi Xperia users,
I am the owner of a Xperia Arc S ICS .587 rooted that gave me satisfaction until some months ago ...
I was driving in my car with Google Maps and then the phone suddenly shut down. It was a SOD : I tried several times to reboot the phone, I removed the battery several times as well, but nothing. Finally the phone could reboot after 2 hours ... And since this date the phone has a VERY VERY heavy battery drain. It means that when I leave it on a table with a 100% charge without using it, the autonomy doesn't last more than 24 hours. Even when the phone is turned off, there is a battery drain of ~5%/hours.
I tried these solutions without success :
- Purchase of a new battery
- Wipe battery stats, then discharge and charge
- Wipe data/cache/factory reset (without the SD on which there is my apps with Link2sd), and then installation of a new ROM (Ultimate HD)
The day I was driving, I wasn't doing modifications on my phone of course ... just charging and screen active for 2 hours that makes it warm. If the battery or the ROM didn't change anything, I think it's maybe a component that burn/melt.
And some weeks ago, the white band on the side of the battery became red. The white band in the small hole on the back of the phone as well. What does it mean ? (you can see the pics)
I am looking for people who got the same problem ... or who can find what is happening exactly
Thank you

If you let it discharge and turn off, pull the battery out and reinsert it, does the phone turn on?

Well, it doesn't matter.
If it's a hardware problem, best to bring it to a repair shop and get it checked.
P.S The white band near the battery seems to be a fuse of some sort. Strongly suggest to get it checked.

Hmmm, I had the same problem with other phones but for different reasons.
My Nokia 5610 had a piece of paper attached to the battery compartment. When it turned red, it meant that the motherboard had been corroded.
For my friend's Motorola Razr, there is a fuse inside the phone that will blow if he unlocks the bootloader. There is no indication by visual inspection but it will show under detailed inspection.
I think your case may be hardware failure, since you got the red band after your phone got SOD.

The phone is working perfectly, except the autonomy. I think a damaged motherboard would cause bigger problems.
Even if I have a custom ROM, I didn't unlock my bootloader. And the battery became red about 2-3 weeks ago, my SOD was 5 months ago. Maybe the battery begins to suffer from the high consumption.

(SOLVED) Pixel 2 XL charging stuck at 99% all of a sudden

My 2 XL is only a month old. There is no complain about charging before. It was normal. Hit 100% everytime. Until several days ago, I woke up in the morning and my phone does stuck at 99% with charging rapidly status. I've tried to drain the battery and fully charge, try to flash factory image, but the problem still exist. The phone does charge normally to 90%, then getting slow and more slow when hit 95%, it takes very long time to get to 99, then it stuck for hours. I'm using app called AccuBattery, just want to monitor the charge speed. And there it is, the phone stop the charging at 99%, charging speed shows -1 , so basically the phone cut the power input when hitting 99% although the status still not fully charged. Until I rebooted the phone then it will hit 100%.
So what happened to my phone? I'm using original charger from the box. Is it software or hardware issue? Thank you
The first image is when stucked on 99% and the charge speed show -1. After that I rebooted the phone then charge speed increasing, not -1 anymore at 99%. The second image is when the phone says fully charged at 100% and charge speed back to -1, which is normal if the phone already fully charged.
EDIT:
Solved - see my post below

What is it at though? But on all my previous rmas, I had sometimes great issues in from charging past 98%.. I would have to turn it off for it to register that it's actually charged to 100% and more than likely it would drop to 99 as soon as I unplugged it.

Yeah, I'm planning to do that. I'm just uncomfortable with my phone acting weird, it supposed to hit 100% everytime normally like before. And a little afraid that this issue would make any affect in the future, broken battery or worse. If there's an explanation how this is happened and it's safe, then I might not make any complain anymore.

I had the same issue with my Oct 18 2 XL.
Download Accubattery and "calibrate" your battery.
It removes a file (.bin or something) that resets the batter charge percentage.
I really think the 99% thing is harmless, but if it bugs you (I get it) Accubattery will remove the file that resets it.
Good luck!

I currently using AccuBattery as shown on my post attachment and I didn't found any "calibrate" menu inside the app.
I've done so many methods, like drain the battery to 0% and charge it or re-flash factory image but seems none worked. So I search on the internet about delete the .bin file under root/data folder, but I didn't found any folder called data on /root (currently running android 10). I'm stucked.
So I'm thinking how if pull the battery out and put it back maybe it will reset something, but it seems impossible to do with myself. Until I found a method to hard reboot the phone with press power button + vol down for maybe 10sec. My phone was 75% at that time, after hard reboot my battery increased to 78%. Then I tried to charge the phone and voila, hit 100% normally, didn't need to unplug and replug to hit 100% anymore. It's been 3 days my phone is act normal again. Hope it will lasts forever.
So my conclusion is, seems the hard reboot method somehow force cut the power from the battery to the phone just like we pull out battery then put it back and maybe it's reset something maybe like batterystats or anything. Idk. But I'm glad nothing happened and it was just software error.

I currently using AccuBattery as shown on my post attachment and I didn't found any "calibrate" menu inside the app.
I've done so many methods, like drain the battery to 0% and charge it or re-flash factory image but seems none worked. So I search on the internet about delete the .bin file under root/data folder, but I didn't found any folder called data on /root (currently running android 10). I'm stucked.

When you download Accubattery, open it, it automatically 'calibrates' your battery (see pic)

Oh, I just realized that. Thank you. But I think it didn't work for me. Nvm, my phone is normal now :laugh:

I had somewhat of the same issue with my phone too. Would sit around 98% then after taking it off the charger overnight, my battery would drop like a rock to around 85%. No idea if I was just imagining things but I don't remember that much battery life wasted away like that overnight when not in use at all.
I also sent mine in for RMA last Thursday and get it back later on today so hopefully the issue will be resolved.

I have also been experiencing the same issue since upgrading to Pie last year. Once it returned to normal for 1 month only and then went back to 98% charging issue until today

I would assume broken battery. Never experienced drain so much like that when not in use. My phone normally about 1-2% drop overnight (always on display off). It's great you got replacement, but check twice for screen, 2 XL known for defective screen.

Yeah I am content with the RMA replacement it's just fine, no issues thus far. Just annoying the update breaks charging sound file and lockscreen lock/unlock sounds. But I eventually got those issues fixed too.
