Heh, this is a $20 dumbphone from AT&T (Huawei U2800A). It is probably a hardware feature, PC RTC wakeup style. Not sure if the various appphones can wake up at a time, though there ought to be apps or settings to shut down at a time.

On Android I doubt you can completely shut the phone down and wake it up again, but you can certainly kill the network on timers.

There are the more complicated battery saving apps that do stuff like kill 3G while your screen is off and overnight.

I do nearly the same thing, just with flight-mode from 1am to 7am. N900 event editor.

However, I agree with the parent to some extent; I could live just fine without tech for as long as required, but on the other hand the information super-firehose is fun and stimulating in ways a walk in the park just isn't. Keyword: moderation.

My 3-year-old Japanese dumb phone does that. It's a pretty common feature.
