I had the phone on and in my hand when it just flickered off. I was in a 3d game but had only been running it for a couple minutes. The battery was reading about 90% before I fired up the game and it was plugged in to a factory samsung charger at the time. The game sort of stuttered a second or so before it shut down, then blank screen and it looked dead. It was slightly warm at the time, but nothing near overheating.

I held down the power button, nothing.
Tried power/volume combinations with no result.
Pried it out of the otterbox case it has been in since I got it and pulled the battery and put it back in, still nothing.
Pulled MicroSD and sim card.
Tried both volumes and plugging it in to USB with and without a battery, nada.
Left it alone and researched online for a bit, battery back in and nothing.
Plugged into a different charger and still nothing.
Seems no matter what I try, no response at all.
Both the phone and battery are cooled off at this point.

Could this be dead battery? Am I going about trying to force it to at least light up without a battery correctly?

At this point I'm at a loss. I can check the local AT&T store and see if they can at least let me test a different battery.

Last night I did flash the latest SHOstock 5.4 ROM, up from his 5.2. The phone ran fine afterward and I shut it down once since the flash without issues. This phone has been rock solid since day one, never dropped, no water damage, always in a case, pristine condition physically. Nothing to cause any trauma. Never even overclocked, but did have it running .25v undervolted at all speeds for a while.

I bought this last November, so it is less than a year old. Insurance is being paid but it is also within one year of purchase. So warranty should still be in effect? However, if it is this dead I can't flash it back to stock for warranty return, so what are my options there? Call it in as a warranty claim and hope for the best?

Edit: just tested the battery with a voltmeter. It is reading 4.1V, not sure if that is too high for a battery that is rated 3.7V or not. I'd guess no, so bad battery theory is likely out, unless it cooked the phone.
<edit> and I'm so frazzled from my beloved phone dying that I posted this to general instead of Q&A. argh.

I wouldn't rule out battery failure. Batteries don't power devices with voltage, and that voltage will only be discernible as an indicator for a very short period of time before it actually dies. You'll need a battery tester to check its actual amperage output, and I'd recommend looking up what it should be, along with its amp hour rating. Wish I had more to offer, but I work with dc backup powered systems, and they're a pain in the ass to catch with a voltmeter.

I777 gets it done, gnex just for fun

Yeah I know what you mean. I once had a car battery fail, read about 12V just fine but didn't put out enough miliamps to power even the dome light.

Taking lunch right now and headed to the retail store in town to see if they have a battery I can swap to test. More worried that I can't return to stock, really can't afford a $400 bill to replace this sucker if they catch that I've flashed it.

Had to drive an hour to the AT&T Device Support Center but its replaced now. I think the tech there was a bit surprised at how dead it was. He was figuring to just run his recovery tools and fix it right up, but got nothing.
Oh well, at least I'm not stuck on my old Tilt 2 running WinMo anymore. Though I do miss my keyboard a little bit. ;)

Why has this been happening to the S2's a lot? It seems like it anyway. Mine went through something crazy a couple of days ago where it wouldn't turn on and it was soft bricked.

After I got EnergyROM on my Tokyo the software worked as well as could be expected for WinMo. I also had a pretty much fully functional Froyo Android running off the SD card. The microphone finally died on it though, and the cost to replace out of warranty was more than I spent on the GS2.

I forgot how nice having a keyboard was though. Faster and more accurate typing plus you can still see the whole screen. Maybe that captivate glide wouldn't be so bad after all... Lol
