iOS devices "shutting down"

[Gios]

Something weird happened in the last couple of days: last Saturday my brother's iPhone (4 on 5.1.1) somehow "died", he asked for my help. It wouldn't turn on, had to force DFU mode and restore it. His power button has kind of gone bad, and I blamed it plus my brother's incompentence.
The reason I'm creating this thread is that the same thing happened today to my iPad (3rd gen, running iOS 6 b2). I thought I didn't charge it tonight but it wouldn't work even while charging, I tried DFU and restore and the battery is in fact fully charged.

Is this happening to anyone else or just a weird coincidence?

My iPhone 4 died on Thursday. I couldn't get the iTunes screen or anything when I held the sleep/home button while plugging it in. Then on Friday evening I plugged it in and said battery was dead. Let it charge and now I'm good. Thought it was weird. It was the only problem I've ever had with my iPhone. Don't know what happened but I'm all good now.

I had the same thing and it turned out to be a totally dead battery. Once plugged in, after a minute or so, I got the red battery. Couple hours later on the charger, all normal.

I couldn't figure out why it went dead because I charge it every night. However, I discovered the charger wasn't pushed all the way into the wall outlet.

Same thing happened to me. Loose connection on the power cord.

As I said I'm sure it's not a simple battery charging issue because once restored the iPad was fully charged, in fact I'm still using the same charge since then and it's still 63% (thumbs up for iPads battery life !!).
