My SGH-S730m (no device forum for this phone yet) battery percentage was at around 80% when I turned it off. It was placed in a pocket with another device. I can 100% confirm it was off for a complete 4 hours.
When I turned it on, the battery level was at 5%.
The battery still charges, the phone still works. The battery has not exploded yet, and is currently at 45% charge. I am using samsungs OEM battery (it came in the box with the phone). I have had this phone for just more than 2 months now.
What the heck happened? Is my fuel guage messed up?
Have you ever tried battery calibration?
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times
I also is same...

That might be a fix, but im looking for the reason behind this problem.
Does anybody know what went wrong? My phone still works (if that even means anything).
Sometimes it happens that the chip goes mad. It happens with every android phone. You're lucky that you have removal battery. Some devices is difficult to do the above trick. I think when you do a full charge and disconnect the battery from the phone for 5 minutes it will be good again. I'm not kind of advice let battery go to 0 because you can ruin li ion battery with a full discharge.

How long did you have this phone?
Can't you get it exchange for a new one in case the phone has a problem?
I don't know where you from but in Europe you have 6 months for battery and 2 years for phone.

What I meant was, if it's still within it's warranty period you should get it exchanged.
If not, swap your battery with someone and see if it's your phone or the battery.
Indeed.

I won this phone for $7 at a stack-em machine. I doubt it has warrenty.
Sorry pal I can not answer that. But try the exchange battery suggestion from the other user. And try mine for calibration.

Is this a one time only issue or did you get that a lot?
One time only can be from a stuck process in your phone
If you get that a lot => try the warranty

One time issue. I noticed that the phone was getting really hot (even though it was off).

Nope, you can't. It reads 0% while actually it's voltage is way above 0mV (actually somewhere above 3V) and that's a preventive so that you can never discharge it even close to full discharge because going over 0.5V below the nominal voltage would ruin most Li-Ion batteries so it simply doesn't even allow you to do that. And besides, from where do you think it draws the juice to blink the LED when you try to turn the phone on after a "full discharge"?

You should buy a replacement battery then ASAP, they're pretty cheap these days. You don't want Li-Ion packs overheating and the liquid inside them catching on fire.
Li-ion battery are intended to work between 40 and 100 working below that is in most cases the ruin of a battery. And experts say even 98 % slhould be optimal full charge not evem full.

Can you please quote some sources and prove that this is not just a speculation by yourself? I understand the physics of electricity and the foundations of marketing and economy well enough to say that what you wrote is utter nonsense.
Just read the thread from gokhanmoral from here. On galaxy s3 original development thread.

I already know what the problem is. What I want to know is "what" happened to the battery.
Why, would the battery die so quickly when the phone was off? Why, was my li-ion battery discarging the energy as heat? (which would expain the heat while it was off). Why, does my phone still work?
Years ago, I fried a pocket pc by using a 10A charger instead of the usb 0.5A standard (is it 0.5mA? - I cant remember anymore). The battery didnt actually explode, but it got HOT! Really hot. I came back 10 minutes later to discover that my battery was discharging while plugged in..
I fried my fuel guage hardware. Tried to save it, but there was no way. Even after unplugging the 1 pound beast from the charger, the phone was discharging around %4 every 30 seconds. I learned my lesson from that horrific event (I loved that phone so much).
Now, who "actually" knows what happened to my battery? Anyone? I dont need a fix - so dont bother posting if your going to tell me to buy, sell, or repair, and not tell me why.
Hello.
I have Samsung Galaxy Note I GT-N7000 I have problem... serious. I was watching Netflix and recharging my phone. Then i got warning of low battery and it turned off after 5 minutes and it was "charging" Well then i leaved and next day, i but it to charge. Battery image appeared to screen and was there about 10 seconds. After 2 hours of waiting i tried to start the phone but it didn't. Now i tested the voltage of the battery and how ever (-0.00 V) No life in whole battery Then my dad told me to take out the battery from phone and leave it to table for an hour and check does it work.
Does anyone else have/had problem where Battery has died?
Can it be fix'd?
I tried cleaning Micro-USB port!
Thanks.

How long have you had the battery? They don't have a very long lifespan and die quite dramatically. If you put it on a flat surface can you see its bloated and spins easily? If so it's definitely gone and needs replacing.

I have found in the last couple days my nexus 5's battery % to go UP when idling off the charger. I have no idea why this happens, anyone else seeing this? Look at the last part of my battery graph and note that it was not charging at any point. It's only 1-2% usually, but it always catches me off guard

Yes it happens to everyone, at least it happens in every N5 battery screen I've seen. It seems it's recalibrated by the graphic, most probably just a software problem and not a hardware one.
My GS3 and GS4 were the same.
Hi all
I will be getting my nexus 5 tomorrow and was just curious if there are ant does and donts with regards to charging the battery. The reason i ask is i currently have a HTC sensation and after 18 months the battery had to be replaced as it was simply not holding its charge. My routine was to charge it overnight every night and use it during the day.
Does charging it through the night cause damage? im just a little bit more concerned as i will not be able to replace the battery with it being sealed.
Thanks for any tips
Chris
Hi,
Take a look here: http://forum.xda-developers.com/showthread.php?t=2511647...
I used to do the same thing with my HTC Incredible... I learned that it can damage the battery over time by not allowing it to hold a charge. Now, when I get home (depending on remaining %) I charge my phone, and unplug it during the night.
If for some reason the battery dramatically drains overnight, I'll charge it when I'm getting ready to leave in the AM.
That is just my method, but I have had great results with it for my usage.
Plug it in...

Thanks i read the link ...and i also think i probably wont charge mine overnight, im convinced that had a hand to play in my battery going
I have had this phone since it was announced. I plug it in every night when I go to bed and leave it plugged in till I wake up. My battery is fine. I have done the same with my note 2 also. Never had any problems

Same here
It's not hard to pop the back cover off and replace the battery when it goes bad. I just dont worry about it and charge whenever and take it off the charger whenever.

I have Cataclysm Rom.
and lately I have a problem with my Nexus 5 Battery.
every time I charge my nexus 5 to Full and keep it without using it drops to 90% or 85% without any using.
and lately i charged the phone and then i shutdown my phone and in the morning i powered on my phone and I found my battery 79%
and don't know why.
but I think my battery life has gone. and I'm sure that there is no app using my battery.
Thank you in advance.
Sounds to me like it is time to change the battery. My battery was about 2 years old and also dropped quickly when just navigating the phone settings.
Swapped it for a 1 year old battery from another phone and now it is fine.

thanks for replying. I think I should replace my battery
Replacing the battery would be the cheapest solution unless you have some other way to testing the phone to see if it really is the battery that is defective.
