Defective S3 died 2 days after i bought it!!

Hey Guys,
I have been following this thread since a while and finally took the plunge with the S3.
it was a blue s3 and i loved it.
All stock, not rooted nothing..
So i was downloading my games and apps the first day all went well
the second night, i bought NOVA 3, and put it for charge while downloading the 1.7 gb data for the game over wifi.
i woke up in the morning and the phone is dead, it shows a yellow connect it to kies message.
I dont know what happened?
took it to the service center, they tried re-installing the firmware, but no avail. finally told me they have to replace the motherboard it was fried.
I fought with them and managed to get a replacement unit which im gonna get on monday.
The ordeal aside, i want to know, is it possible this happened because i downloaded too many games(6 actually)
each with about 400 mb data.
can a phone get bricked if i download nova 3's data of 1.6 gb
cause i am going to get all my games again.
so help with the solution!!

probably a 1 off defective unit.

You left it charging overnight right, have you considered a power surge may have fried it?
It's better to wake up early in the morning and put it on charge than to leave it overnight.
Sorry about your loss though.

Not true. Modern mobile batteries like s3' have overcharge guard

To answer your question, you just had a defective unit that's all.

I think heating was the problem... I remember few guys with sgs2 with same problem reporting..

I don't think the game's could do anything wrong to you while downloading.
Btw while playing games on SIII take care as the Phone's temperature reaches the sky and literally i have to close down the game because the phone becomes too hot.

power surge and over charge are totally different things. over charge protection would not prevent a power surge.

Most probably just a defective unit.
I left my HTC Sensation charging overnight once, and somehow there was an app running continuously and when I woke up the phone was scalding hot to touch. I freaked out and pulled the battery and let the whole thing cool before I booted it up again. Might not be relevant but just goes to show that our phones can take more heat than we think.

Well I have been charging my handsets overnight for at least 6 years now and I have never had a fried nokia, hero, desire, sgs2 or sgs3 ever.
Charging overnight is safe

Use it...... Charge it often... try not to discharge the battery to zero. Calibration is not needed... This is a newer phone with new battery technology.

thanks I thought to calibrate it you had to discharge it fully then recharge
Sent from my Nexus 4 using xda app-developers app

Yeah just use it like normal. Don't worry about the battery bar too much.

Calibration is a myth
Sent from my Nexus 4 using xda premium

It is a good idea to charge for solid 8 hours and discharge to around 10% the first 2-3 cycles of the battery to condition it. But after that, use as you please, no memory effect or calibration or the like.
Only thing I would add, do not drain completely flat (0%) as it can negatively effect battery capacity, tho modern batteries usually have guards to prevent full discharge, for that reason
Calibration (full discharge) was for Ni-MH battery technology, and is actually a bad thing to do with Li-Ion/Li-Pol batteries

There is no memory effect any more. Just avoid killing the battery fully or leaving it charged for extended sessions, because the heat hurts the battery.

The thing about discharging to zero damaging the battery is another myth. The phone will report the battery at zero well before it reaches the "real zero". So there's an inbuilt safety margin that means you don't have to worry.

Calibrate the battery by running it down to 0% and charge it fully.
You can also root the phone and flash a custom kernel that offers great battery life.
Other things you can do...
Turn off sync, turn off GPS, turn off Google now, and lower brightness level to a minimum.

Yeah i was more talking about calibration. Is Just one discharge cycle enough ?
Sent from my Blade S using xda app-developers app

There's no such thing as battery calibration. Just use your phone normally, charging it when you want to.

Don't calibrate now.. your phone will already have the best calibrated battery settings.
Calibrate when you flash a custom Rom and that too,if you face battery problems. Otherwise no need. You'll do more damage otherwise. No need to calibrate if you flash a kernel over stock either.

You dont calibrate li ion battery.

And you should never purposely run it down to 0%.

It is a bit of a misnomer as the phone is calibrating the battery scale to match the discharge of the battery. It isn't that there is no such thing, it just isn't what people think.

Get the latest Franco kernel on it. That is all.

Weird battery charging graph

One of the strangest charging profile I've seen.

That is weird. Miscalibrated battery, maybe? Try a full discharge, then recharge.

It's not recommended to do often, but discharging has been known to solve issues with improper calibration.
Besides, you can't tell me you've never used your shiny Nexus 4 to 0% before ;P

Did you restart your phone while it was charging? I've seen strange dips and spikes in the battery graph on my Nexus S when rebooting while its charging. I haven't seen anything like your graph on my N4 yet but I don't check the graph much plus I've only had the phone about a week and a half.

Note 3 Battery Problem

I have a galaxy note 3 N9005 and the battery life is not what it should be. I've owned this phone for about 5 days. I always have power saving mode on with all the smart and air features disabled. I charged my device to 100%. Does anyone know how to fix this?
Thanks

Wow, that's some horrible battery life. I'm not seeing anything like that on my device though.
Did you condition the battery probably?
And of over 3 hour screen on time.
My advice: try to recondition your battery
As in, let it die, recharge to full from wall outlet. Do that about 3 to 5 times. Don't force it to die just use it normally so the battery will discharge power properly this will causes it to hold more charge.
If you do that and the battery still doesn't hold charge then your battery is good as dead.

Wow you get amazing battery life! Thanks for your help

Is your screen brightness set to 100%? And was what you're doing over excessively white? Because that might account for some of it.
Did you unplug it last at 100% battery, or somewhere halfway? Because from the look of that table, you unplugged it around 50%...

You have defective battery plain and simple. All this talk of calibration is for birds. This lithium batteries don't need that.

I would just to head off a Pandora box of ish. I pretty sure it's battery but why not just get new device get a second unboxing feeling plus the sooner you do it less attached you are to current device. Then pimp out new device with DynamicNotification. My 3 cents

I have been having some issues as well
its getting better since last Thursday since i got it but its still not 1 day.
it used to be 5 hours from 100% to 20% brightness in auto
Do we have to "train" the battery to achieve max capacity?
is it battery defect or phone?
