[Q] Mytouch 4G Slide bricked while using

I'm no expert, but it unfortunately sounds bricked to me.

Similar thing happened on my 1st MT4GS after like a week of owning it. We were on vacation and I was playing fruit ninja, slashing happily away as the phone was plugged in for bedtime. All of a sudden it turns off. I'm like WTF, it was charging! But it apparently wasn't, and similar symptoms to you. No other lights/charge/indication of anything working. Just the dim red light in the track pad I could get to go on and off. Since it was just over a month old after I got back from vacation, I wound up having to ship to HTC rather than walk out with a new one from t-mobile, but they sent me a replacement I've been using since.

So sorry I don't have better news, but it sounds like what happened to me, and it was dead and had to be replaced.

Hi,
This has happened to me two or three times but thankfully I have a few other devices so I needn't worry much.
When this happens I take out sim, SD and battery for a week or so. Upon reinserting battery all was good each time.
If you have a spare try it, I can't say for sure if we are on the same boat but its worth a shot before throwing it away.

Edit
Here is a link that I and a few other discussed our issues, none the same but all similar.

Also there are plenty of other threads I seen on this as well, search around a bit and hopefully you'll find an answer
Best of luck!

So there's some threads I just shouldn't read ...

After coming across this today my phone has started turning off by itself (doing routine things, like pressing the "Read" button on an SMS). There's gotta be a weird coincidence there (I had an underclock issue where the screen wouldn't come on a couple months ago while earlier that day I was reading the post on how to replace a bad LCD panel - so I get to overreact like that).

I think my issue is more about battery as I have been tracking it the past several hours (three shutdowns in a row at 60% battery, and then one ten minutes ago at 20%) but it continues to work itself out (with some weird stuff like notification panel crashing on me on one of the last reboots).

I have what I presume is a cheap 1900mAh battery (EZOPower) that is starting to show it's wrinkles. I have dropped the max processor speed a notch according to a recommendation in this post:

...hopefully that was the issue. I nandroid'd my device just in case something goes wrong. If it continues, I'll swap batteries and see.

I'm hesitant to shell out for a couple Ankers because I currently have my eye on the LG Optimus F3Q (although getting one would be three months away, I gotta have priorities).
